  1. I talked to an alpinist once about my amateur experience climbing the most simple rocky slopes. He told me just one thing: "When your fear tells you to stop, then stop and make your way back, on all four, if necessary.". Best advice I ever got. There is no room for error on a mountain and if you don't have the experience to do it safely, then don't do it at all.

  2. Unmarried young men... that's what you get when the rich guy has four wives and three poor ones have none.

  3. The essential failure point here was the mind of the company owner. Every event thereafter was just part of a long causal chain.

  4. The US rust belt could be revitalized just as nicely as the German Ruhrgebiet has been. All it takes is political will. That, unfortunately, is lacking.

  5.  @mewfortwo  I didn't mean to make a joke, actually. I apologize for the smiley. I automatically put that at the end of almost all of my posts. It has become a bad habit, but I agree that it is not appropriate in this case. It's simply a fact that people on minimum wage who don't have a support network (like parents or a partner who has a better paying job) have to work two jobs in one way or another. Realistically I can't see how else one can survive in the US. I also agree with you that working oneself to an early grave should be a thing of the past, but it is not. There would be ways for society to solve this even while maintaining minimum wage work, which is important for some sections of the economy... e.g. by providing affordable housing, healthcare and education to give people at least a fighting chance at upward mobility. At least that is what I think... but you can be sure that nobody takes me seriously around here. I am a humanist, after all, which is worse than being a communist.

  6.  @BennJordan  I can read the description all day long and his point still remains valid. ;-)

  7. Yes, October 7 was completely unnecessary. So was hiding behind the grandchildren. These people are acting irresponsibly.

  8. Folks, you can easily simulate this with a circuit simulation program like LTSpice. When you do, you will learn that electricity does not flow inside wires. The energy flows in the electromagnetic field outside the wires, hence the potential change at the switch will immediately start propagating along the wires at the effective speed of light along the transmission line formed by the two parallel wires, hence anything that has to do with the speed of light in vacuum is already ruled out by the existence of a dielectric between them (which is needed to keep them separated). Look up the theory of a transmission line pulser and you will have your correct answer.

  12. Because politicians have to cater to stupid voters, kid. China's EVs won't make it to the US any more than China's ICE cars did. It's simply much cheaper to produce a car to Chinese regulatory requirements than it is to US requirements. By the time a Chinese manufacturer adjusts designs for the US market the cost advantage is mostly gone and then they would have to build a sales network (the US dealership requirements are arcane, just ask Tesla) and a brand. There is hardly a business case to be made for either investment. OTOH building solar panels in the US is basically a no-no. The cheapest Chinese panels are the cost optimum.

  14. What does Israel need diplomacy for? It's executing a simple police action against murderers. It does not have to ask other nations for permission. The Arab world needs to grow up.
    19
  15. Companies aren't lying about it. You can look up the employment numbers of larger corporations on the internet. You can look at hundreds of thousands of job requirement postings. They aren't putting those up for the fun of it. There are people who are lying to you about this (whoever promises you the sky for two weeks of way overpriced boot camps), but it's not "the industry". The industry is, if anything, offering you a very bleak outlook on your future IF you care to read their actual publications on the topic. Which you don't. You still believe that this is a get rich quick scheme. It's not. It's a mature industry that offers bleak career prospects and endless amounts of unpaid overtime to every low EQ kid who wants them. ;-)

  16.  @lollius88  Because cursing won't help her. It's a bad habit without any upside for her life. She should be doing things that would make a difference... like teaching her children that hate is not a solution.

  17.  @Samb0o0o0  At least they were hiding behind his grandchildren and not the grandchildren of innocents. I guess that counts for something. Well, they are all martyrs now, right? How does Allah treat the little ones in heaven? Same as the adults? Lots of personal servants? What does the Quran say?

  18. Taiwan has three major industries: semiconductors, the exploitation of mainland Chinese workers and bubble tea. :-)

  21.  @pauladamson9459  Because in that case the electrical energy is flowing into the wire instead of along it. If wires get hot, then we aren't using them correctly. The proper use of conductors is as boundary conditions for electromagnetic fields. An ideal conductor will keep the electric and magnetic components of the em field outside of its volume. In a non-ideal conductor the field can penetrate into the conductor but it is exponentially dampened. This is called skin effect and the skin depth goes with the inverse of the square root of the frequency. For DC currents the skin depth is infinite, which means that the field has penetrated the conductor completely. In that case the Poynting vector (cross product between electric and magnetic field) is non-zero inside the conductor and some or all of the electrical energy gets deposited inside the conductor.

  22. Yes, and the entire shebang used to be available as a commercial product that was called "cable pulser". I used to have one. They are great at making flat-top pulses in the ns-range.

  23. That's because the headline is not even true. If you are trying to design a CNC router, then bending is to be avoided at almost all cost, otherwise your machine will only do three things: 1) destroy your workpiece, 2) destroy your tools and 3) destroy itself. If you don't understand why, then you still have a lot to learn, "mechanical engineering student". Engineers who are designing bridges and railways and pipelines, however, have learned centuries ago that compliance against thermal stress, etc. is absolutely required to prevent failure. You just don't know what you don't know.

  24.  @brontehauptmann4217  What is "scientism"? A word you made up to feel better about having failed high school science class? :-)

  26.  @humeanrgmnt7367  Challenger didn't blow up on the pad, but it is a good example of where faith based reasoning "Nothing ever went wrong too badly, so we have faith that nothing will ever go wrong in the future, either!" gets you. Faith is an accident bound to happen.

  27. The assumption that Israel will eventually leave Gaza is unrealistic. It's much more likely that they will empty it out.

  30. People didn't have a lot of kids back in the day because it was their wish. It was simply a necessity because of very high infant and childhood mortality. The overall growth rate of the human population was in the low percent range for millennia despite families that had half a dozen or even a dozen births. Children didn't stay on the farm because they wanted to, either. They simply weren't afforded economic opportunities elsewhere or, worse, they were bound to a Lord and couldn't leave even if they wanted to. Women were either married off or they were considered parasites in their own families. The second, third etc. born son had no chance of inheriting the father's property and was either cheap labor for the first born or he had to look for work elsewhere. That often involved becoming a soldier, a monk or, worse, a criminal. So, in effect, living in the past was a miserable affair for almost everybody except maybe a lucky few who were born into the richest and most influential families.

  31.  @Pulikaeshi  There are alternatives to Canadian softwood? Are you growing a forest in your back yard by any chance? ;-)
    12
  32. There is no debate about that. A world with one billion people living happy, healthy lives would be far better than what we are having now.

  33. This matches the experience of my family members with wildtype, delta and omicron, except that it often lasted up to 14 days and one person still has long COVID-19 symptoms.

  36. Spinoza couldn't afford to be a hard atheist. The people of his time didn't look gently on those folks and he wasn't rich enough not to care. Free choice of religion didn't exist in Spinoza's world, yet. To look at it any other way is to be completely blind to historical reality.
    10
  37. @ There has NEVER been a historical parallel to what is happening now. Nobody knows what to do with five or six billion people who have next to no economic value (too young, too old, too sick to work or not educated enough to produce significant value). It's unlikely that it will lead to a reduction in world population because we can produce enough food and housing etc., but the economics of it is still an unknown.
    10
  38. A nation has entered terminal decline when it starts celebrating royal weddings. Exhibit one: Great Britain. Russia's goose is cooked.

  39. Experience is learning. It's just learning that you can't do in school. It's one thing to learn to configure a Raspberry Pi as a server and it's a completely different one to upload a new bare metal search algorithm on a million Google servers. Google will trust you with the latter... AFTER you have acquired the necessary experience to do it safely. Why would they let a rookie crash a hundred billion dollar search business? :-)

  40. Yes, you were pawns of Iran. Israel will stop that for you for a little while. What you do with that freedom afterwards is up to you... but I am not holding by breath. Your past performance was less than stellar.

  48.  @LiveType  At 300,000 km length the lightbulb will never turn on because you don't have unobtainium as conductor. That doesn't mean that there is no signal. Of course there is... a lightbulb is just not the right detector. You are basically asking "What happens when I demonstrate my failed physics/EE education?". If you put that on the internet, I will give you the obvious answer: "You will become a troll.".

  49. It's not looking good for Hamas.

  55. Fewer drugs, Dude, fewer drugs.

  56. At this point it's not even clear anymore how many have been killed. I would put this down as another Hamas lie.

  57.  @LiveType  Yes, you do misunderstand what is going on just as much as Veritasium does. This is a simple transmission line problem with, if you want, a mismatched load. So, basically, instead of trying to understand the real physics of it, you are merely debugging/defending a bad electrical engineering design. :-)

  58.  @SR-pr2xz  Yes, we regulate droughts all the time... with reservoirs. What other kindergarten level knowledge can I help you out with? ;-)

  68.  @UsefulCharts  Neither was there a garden with a talking snake or a flood or a guy inside a whale. What there was, though, was the misery described in Psalms. That is where history really is showing through, in the obvious PTSD of the psalmists. These are people under enormous distress, which historically will result in a crescendo of death and destruction all the way to the year 70AD and then again 135AD. And those in the Roman empire who adopted the apocalyptic religion of a new prophet were even more desperate and wished for nothing more than death because life was hell on Earth for a Roman slave of the 1st and 2nd and 3d centuries. So, yeah, what we Christians call "the good book" is really a horror story in disguise, we are just not taught to read it for what it is.

  70. I have been on them a couple of times. The trains were crowded, there wasn't enough space to stow luggage and people were smoking near the doors at every opportunity. The train rides were boring as hell, getting on and off the trains in mega stations the size of large international airports was stressful and the cab rides to and from the train stations were the worst. The experience of going at 270km/h wears off very quickly for those who are used to going at 700km/h in a plane. My small local airport is a much more pleasant experience and it connects me reliably to a large one that has international flights to everywhere.

  71. There is a difference between wanting and achieving. The same happened to Japan half a century ago. It's not that they didn't want it. They were simply not able to do it, despite best efforts.

  76. 1000 casualties a day for the 400,000 Russian men means that basically all of them are on the block within a year. They can either avoid to be sent to the frontlines by whatever schemes they can come up with or they are almost guaranteed to become KIAs or WIAs.

  82.  @iPlayDotaReligiously  Most machine tools are made for highly rigid tooling processes. If the tool is allowed to move in the direction in which it "bites", then we get a destructive positive mechanical feedback where the machine gets deflected ever farther into the wrong direction. The way to counteract that is with rigidity and mass. "Soft" machining can be done, of course and it's highly useful. That's how optical manufacturing processes work, for instance. Grinding and polishing can produce near atomic precision with machines that are all but precise and are completely floppy at the scale of the final precision. I find that absolutely fascinating in its own right. A stone mason is, if you want, also a "soft manufacturing process". He constantly compares the shape of the stone he has with the shape he wants. The tradeoff is time... soft processes take much longer than a rigid process. So yeah, there are plenty of applications, but one has to chose wisely.

  83. China needs to stop behaving like a hurt little boy. It's not becoming to a great nation. The proper response should have been "We are disappointed that the US has decided to withdraw its diplomatic support to its athletes but we we are continuing to invite the entire world to these games. Thank you.".

  84. Fauci and the CDC did no such thing. Their communications were almost all immunology 101 textbook facts. Those facts are not convenient, for sure. Beats dying on the respirator, though, as millions of people could tell you if they were still alive. What "sexual books" did state boards add? Sexual books like Marquis de Sade's "Justine"? Desclos' "Story of O"? Nin's "Delta of Venus"? THESE are "sexual" books worth reading. I very much doubt you will find any of those in school libraries. You probably won't even find them in the fiction section of many actual libraries. I am delighted to report that mine has them, which I find surprising. Maybe the US is not quite as intellectually corrupt, yet, as I thought. ;-)

  87.  @SR-pr2xz  They had a drought in the Western US for the past ten years or so and the golf courses are still as green as ever... thanks to... reservoirs! Another technology to mitigate climate change brought to you by the federal government. :-)

  88. It doesn't change the albedo of the land all that much. 20% of the light absorbed in the panels flows out in form of electricity (or is stored in the batteries) and during the night the panels are radiating IR very efficiently, cooling the air around them stronger than the original surface would have. Overall it's probably mostly a wash. In agricultural applications the shade of the panels reduces evaporation, leading to longer growth periods in spring and summer and allowing species that are less adapted to arid conditions to thrive. Solar shading in agriculture will probably go a long way to offset the effects of global warming on farming.
    6
  89. Education is accessible. When was the last time you went to the library and looked at a book on molecular spectroscopy? Never, right? The problem is not that education isn't accessible. The problem is that educating yourself is extremely hard work. Very few people are willing to put that much work in.

  96. It is not a logical game because logic only applies to classical objects, whereas what we are tracking here is energy. Energy does not follow the laws of logic, which happens to be a commutative algebra. Energy in quantum mechanics is subject to the rules of non-commutative algebras (the commutators between linear operators can be non-zero, i.e. non-commutive). What quantum mysticism like this does is to expose the casual viewer to a very naive understanding (or, better, non-understanding) of the theory, which causes unnecessary confusion. That mechanics is somehow non-commutative has already been known since the early 19th century, when the Hamilton formalism was developed. The classical equivalents of these commutators (Lie-brackets) are already showing signs of these internal mathematical structures in the theory.

  100.  @SpaceMan-f6d  The floor is accelerating in the inertial system of test masses on which no forces are acting. You need to pay very close attention to how force is defined here. Gravity is not a force. Never has been, never will be. Even Newton knew that. :-)

  101. Maybe not. The typical construction seems to have taken five to ten years, well within the strategic time frames of a typical monarch. They were also often not built individually but as part of a centralized military planning effort. There is one more component that nobody seems to think about: work creation programs. Unemployment was a politically sensitive issue even back then. Unemployed starving people do stupid things (crime and revolution), while employed people are well under control. They have something to lose, a home, a wife, daily meals, respect by the community etc.. Political leaders were no less aware of these issues in antiquity and the Middle Ages than they are today. And what would you like better? A guy building a castle for you or the same guy plotting against you because he is desperate?

  102.  @motivationmonster596  People misunderstand physics. Physics treats nature like an onion, with many layers. We can use different approximations for different layers of phenomena. Classical electrons are fine for many applications, so are quasi-static fields. And then there are some things for which they don't work. That's when we deploy Maxwell's equations, quantum mechanics and quantum field theory. If you want to build LHC, then you have to understand the latter. If all you want to do is to explain water electrolysis in 10th grade, or so, then none of that complexity is necessary. Or, as my first theory professor remarked at the beginning of his first lecture: "Ladies and gentlemen! Pay attention. Physics is the art of the approximation. If you can't deal with that notion, then there is the door. Take the path across the campus to the philosophy department. That's where they will teach you to think in absolutes. We will have none of that here.". Everybody laughed, nobody left.

  105. The more important implication is this: if Ukraine asked for the service, that means the US government is not giving Ukraine access to its own space based military communications channels. If one is a little more primed towards conspiracy theories, then this may actually be viewed as a misdirection... and Ukraine may actually have US support in this area, but the US government wants to have plausible deniability and the story is basically the cover for what is really happening. I am leaning towards the non-conspiracy version. The US is not interested in direct Ukrainian access to its space assets. It opens up too much of a security loophole, especially if the Russians manage to get their hands on the necessary hardware because one of the drone ships fails without exploding. Having said that, it's at most a temporary setback for Ukraine. The ultimate goal for all nations, Ukraine included, are perfectly stealthy autonomous drones that do not rely on any outside connectivity, not even GPS. This is not nearly as hard as people might think. It has already been demonstrated by university students in PhD theses. Ukraine just has to tweak that research a little bit to develop reliable enough solutions for its drone fleet.

  112.  @Irrazzo  One can easily carry out Schroedinger's cat as a real experiment. Even at home. It will be just as pointless as it is as a Gedankenexperiment. The problem isn't Schroedinger.

Everybody is focused on intellectual debris from the 1930s instead on handing out the correct explanations.

  123. I had a colleague in the city who told me that he wanted to have bigger bedrooms and a large yard for his children. He quit and moved to a small community some 20 or 30 miles from Denver, I believe, where he got it all. Large lot, large house, good schools and a better job title at a smaller company. He didn't get any more money, but he was much happier with the new arrangements than with his cramped and expensive lifestyle in the city.

  129.  @Brianboy9494  Approximations are meant to make our lives easier. They have to be "good enough to be useful", which means that only the practitioner in a field can develop a good feeling for the range of applicability of an approximation. You are of course correct that physicists are usually able to smell an approximation from miles away while the layman is, at best, guessing what it is that he is looking at. That's a serious problem in science communications and not just in physics. That is my reason for pointing them out wherever I see somebody misusing them.

  134. The floor of the elevator is constantly accelerating with 1g upwards. There is a so called "waterfall interpretation" of general relativity that thinks of spacetime as constantly falling into the center of a gravitating mass distribution. The floor that you are standing on therefor has to cause a constant upward acceleration in this "waterfall" inertial system to keep you at a constant radial distance.

  140.  @christianlibertarian5488  That proves that consumerism was the main economic driver in the US first. It does not prove that "nothing" was being made anywhere else. Indeed, luxury car manufacturing at that time was dominated by foreign companies like Mercedes, Rolls Royce and Italian sports coupe makers, not by American ones and beautiful consumer goods design was mostly a German and Italian past-time. And let's not even talk about the rise of the Japanese in the consumer electronics space of the 1960s. Sony transistor radios were a true innovation, followed by the Sony Walkman. If anything, it took Americans two decades to catch up with Japanese electronics design after Sony and Phillips invented the CD. We also completely lost the tv space to Japan and South Korea. On the American side it was Steve Jobs who brought good design back to the US almost single handedly. ;-)

  152. He doesn't talk about gender. He talks about sexual reproduction. Listen to what he says in detail. He says that gamete size is a binary. Gametes are our reproductive cells. Sexually I am a man because I can only make small sperm cells. Women have ovaries to make large egg cells. I don't have those. Woman don't have sperm. For all practical purposes that's a binary. According to Wikipedia the number of people worldwide who have been reported with ovotesticular syndrome (true hermaphrodites) is on the order of 500, which makes me assume that there are certainly no more than a few thousand (less than one in a million) people around who have the ability to produce both types of gametes at once. That has nothing to do with the gender fluidity discussion that is real and important for a very large number of humans (potentially several percent of the population). I would not try to mistake one for the other. Biology is NOT the right tool to have this discussion and Dawkins is NOT the right person to ask. He will answer correctly, but the question he answers is not the question that was asked.

  153. It's much easier to work with a patient who has been given a diagnosis. It doesn't matter whether it's spot on or not. What matters is that the patient has to agree, intellectually, that something in their life isn't going right. That's an absolute necessity for therapy and it becomes much easier if that "whatever is going wrong" has a name. You can't get anybody to submit to a process that is literally mind-altering without agreeing to the need to alter their minds. How are you going to get to that point if you aren't even willing to put a name on it? We can talk about whether we are over-diagnosing and over-treating, but that is a completely independent question.

Fact: in 2016 the federal government collected $35 billion in customs revenue. This year it is collecting approx. $100 billion. The increase began under Trump. By the end of Trump's second term the federal customs revenue might be at $120 or $150 billion and ALL of it comes out of YOUR pocket. It's just a hidden tax on the poor. :-) If you think that Trump caused the government to shrink, then think again. He greatly expanded it in the tariffs area and now the feds are addicted for that money. It's much, much easier to raise than with taxes which people will notice right away. :-)

  175. Energy conservation requires (through Noether's theorem) that the universe is time-translation invariant. We can see that the universe is not time-translation invariant, hence there is no globally conserved quantity called energy.

  180. You got it. The theory is, indeed, about the flow of energy between systems. "Wave function collapse" is simply a very, very poor choice of words for the irreversible transfer of one quantum of energy from the original, isolated quantum system to the measurement system. Energy never had paths, not even in quantum mechanics. It doesn't have "location", either. The potential energy in a spring is not somehow concentrated in the center of mass of the spring. The kinetic energy of an object is not in the object. It's a function of the relative motion of the object to a rest system. A quantum is, indeed, simply the amount of energy that two systems are exchanging. It's not a particle, it's not an object. It's just work that system A performs on system B.

  199. It doesn't. All "the computer" (by which I mean the CPU) can do is to manipulate words of bits. The eight bit word 0100001 can mean different things, depending on which code it represents. It's could mean "a" in ASCII, it could mean the integer 65 in binary code or the integer 41 in BCD code. Which code is assigned to a binary word is implicit in the way we use it in software. There is no "switch" on most CPUs that tells the hardware what a binary word means (even though some historical computers had facilities like that and a few differences , like the difference between signed and unsigned numbers, are encoded in the instruction set to make software development easier and to increase performance of common arithmetic functions). That's the difference between data and its representation and it can lead to some very nasty bugs if you are not careful, especially if you are compiling a program for a different architecture than the one that it was originally written for. Most modern languages are trying to take care of most of that for you, though.

So now you have to ask yourself if you really want to "silence" mankind about completely formal solutions to in practice unsolvable equations. What good does that do, actually?

  207. There isn't. A random coin flip predicts the weather in many regions of the world with 50% accuracy or slightly better. A trivial stochastic model that knows nothing about atmospheric physics can probably do 60-70%. No amount of computing power we have thrown at that problem, so far, gets much past 80-90% as far as I know. In general computation we even have hard, theoretically provable limits like the halting problem. What AI has proven, so far, is that some problems that were deemed hard, like the generation of appealing images, are actually "quite easy". That's a statement about the average human taste, it's not so much a statement about the difficulty of general AI.

  208. It's not a matter of technological barriers, at least not in the sense of e.g. LIGO. It's a matter of new theoretical ideas with regards to the question if there could be non-classical effects of gravity that are strong enough to cause a detectable signal. Personally I don't think so. Experiments of this kind are often based on some unusual physical assumptions. An entanglement experiment, for instance, is not sufficient for quantum gravity because classical gravity entangles systems just fine. Entanglement per se is not a quantum effect. A quantum effect detection requires quantized energy exchanges and those are just so far down the rabbit hole that it's not even fun talking about them.

  211. One should probably point out that life in basically every country in the Middle East is dominated by "a constant fear of persecution and death". It's not particularly limited to Israel, Gaza or the West Bank. That fear might be less in the rich Gulf states than in Syria or Lebanon or Iran, but it is there. It's a design element of autocratic governments that dominate the region. No individual is ever completely safe if they decide not to conform.

  212. We have very little historical evidence that monogamy is a particularly strong feature of our species. Some birds are far more monogamous than human beings are. It's also not clear why small human populations should want to be monogamous. If all you have to work with is a gene pool of 150 people (the typical population size of native tribes), of which maybe one third are actually fertile (the other two thirds are either young children or elderly), then that's a very, very small genetic margin with respect to inbreeding. One can also kind of argue that in such settings it was quite normal to experience "other people's intimate acts". Where, exactly, would a couple go to be intimate? That situation did not really change until the modern day and age. Reasonably sound proof bedrooms are kind of a newfangled invention. So is the idea that nobody in the village or small town knew who was frequenting that special "house" in town at night. It seems to me that much of this discussion isn't actually happening in an anthropologically defensible context. It's still English Puritanism dictating a base floor that has never existed, not before, not during and not after they heydays of Puritanism.

  265. It depends. If there are modifications of gravity at short macroscopic ranges, then we might learn something. The Washington group has been using conventional methods in the search for post-Newtonian gravity for decades and that is very important research in my opinion. It might be possible that there is a regime where the new experimental techniques can push these limits further down. Unfortunately, at some scale electrostatic effects will invariable swamp the gravitational interaction, so nature may not let us see what is really going on in that regime.

  266. Penrose has no clue about high energy physics either. He is a relativist. The two sub-fields are about as related as pharmacology and psychiatry are.

  310.  @skhi7658  IMHO it's the way we teach introductory quantum mechanics. I was completely lost after my own QM 101 class. I understood the math, of course, that's easy enough, but I had no idea what it actually meant. I didn't develop a working intuition until after I got into experimental high energy physics, had to read the CERN detector design documents and began to work on actual detector hardware. After that it became clear very quickly that all we are ever measuring are energy, momentum, angular momentum and charge. It was really that "hands on" experimental work that clarified the concepts for me. The textbooks, however, are usually being written by theorists and are staying close to the original "particle" language from the early days, which, unfortunately, is misleading. So, yeah, we have a century's worth of quantum mechanics textbooks that should be rewritten... same math but emphasizing that we are looking at energy that is distributed in a quantum field.
    3
  311.  @skhi7658  I agree. Here is the thing, though: I can not compete with Sean Carrol and Michio Kaku... I don't have the hair and the kind of face that people want to see. Neither am I willing to lie to people to make things "more interesting". That means nobody is ever going to listen to my technically correct explanation that are about as interesting as watching paint dry.

  312. Why is Times Radio interviewing the irrelevant man who has never done anything constructive in his life? ;-)

  313.  @AbleAnderson  His historical perspective is completely wrong. There is literally a mountain of scientific publications about the foundations of quantum mechanics out there. It's not that we haven't tried hard to find out something new about the principles behind it... the simple fact is that we haven't been successful. That is intimately tied to the success of quantum field theory and its great failure to go beyond the standard model, even though it is conventionally not seen that way. Also, his idea that we haven't made a new discovery since the 1970s or 1980s is completely wrong. Like most theorists he seems to be little impressed with neutrino masses. As far as "Gosh, who ordered that????" goes, neutrino masses are the size of a supernova, even if, to the theorist, their incorporation amounts to something like a simple three by three matrix in the standard model.

  325. The economics of a self-driving cab is not as good as at sounds. First of all, you have to buy it. If it cost's $30k and you are making 30 cents a mile (which is kind of what Elon seems to be promising here), that means it has to drive around for at least 100,000 miles before it even amortizes itself. Now, what happens if that thing causes a pedestrian fatality? Then you are in for a very expensive bill and you will most likely go to jail. Is that really worth it? Please note that a cab operator does not have that problem because his cab driver goes to jail instead. I believe Elon forgot to tell you these little "problems" with the business model.

China, like all totalitarian nations, is a collection of egotists who put their own well being above everything else because the nation is not putting their well-being first. This, by the way, is no different from China before communism. It's a 3500 year long history in which the state had to be constantly afraid of its citizens because it has never managed to gain their trust.

I recognized him immediately, even though I have a very poor memory for faces. There was no mistaking him. I looked at his face. It was a face that said clearly "Please respect my privacy. I am not here to entertain you personally. It is not my mission to give autographs on the street. Please leave me walking my own path while you are walking yours.". I did. Yes, I could have forced a much greater man than I am to interact with me for a few seconds. But why would I have? He had his dignity and I had mine. I recognized him and then I deliberately walked past him. That moment that we didn't have, that will always stay with me as one of the best decisions of my life.

  357. And they went out of business. The end. Well, yeah, I agree, though. A well thought out assembly library is a great tool. You also have a point about the slog. "The slog" has been created, in my opinion, by two effects: everything that is server centric requires an incredible amount of plumbing over leaky pipes (many of which contain mostly sewage and deliberately toxic substances) and everybody wants to log the movements of the little toes of the user because they are worth a billion dollars (or so the advertising industry claims). So the same business process that once could be done with 16k of assembly on an eight bit CPU now requires a GByte of frontend, middleware and backend code. Use OOP in addition and you are up to 10GBytes. :-)

  379. Battery storage is for rapid high load demand. That's the current problem that needs to be solved to stabilize the grids because solar and wind can show intermittencies at the minute time scale. The next longer time scale is four to six hours in summer as AC demand continues even after sunset in states that have warm climates. There is also a mismatch between demand and supply in the early morning hours as businesses are opening before solar has sufficient production capacity. This intra-day storage can be easily met with batteries. The much harder part will be to cover weekly and seasonal supply-demand mismatches, especially for heating.

  388. The Tesla factory receives spodumene (LiAlSi2O6), i.e. a mineral with a very high lithium content from the port of Corpus Christi and chemically removes the lithium, leaving aluminum silicates as a by-product. Tesla claims to do this without needing a large amount of acid (which probably just means that the acid is recycled in a closed chemical process). What these guys are talking about is about enriching water soluble lithium brines at the mining site. I suspect that to Tesla what matters is the availability of lithium rather than the total cost of production. They can absorb prices above the market price because they are making vehicles with very high margins. What they can not tolerate is to not have enough lithium in the market to keep making as many vehicles as they can sell. Supply risk management is a totally different goal than cost optimization, so the economics is potentially very different for Tesla. There may also be other reasons like quality control... if their process produces either "better" lithium than what they can buy or "good enough" lithium at a lower cost, then that's a winning strategy as well. Tesla did describe their chemistry in a video, by the way. The main advantage seems to be that they don't have to buy expensive sulfuric acid and they don't end up with byproducts that are expensive to dispose. If I understand this correctly, this is like 19th century inorganic chemistry. You could do this at home with a chemistry kit and maybe a somewhat higher temperature burner. It's a different matter doing it at large scale, of course, but in principle this is, as far as chemical factories go, kindergarten level.

  393. Most people are factually stupid. Sometimes this has consequences and often it doesn't, but that doesn't change the fact. It's also not important. I have a physics PhD but I am absolutely stupid about American football. I don't even know the rules. All I ever see when I watch a game is a cloud of athletic people running around randomly on a green field with lines painted on it. Why am I stupid about the game? Because I never had the intellectual curiosity to learn more about it. That is MY fault and has nothing to do with the game. The same applies to quantum mechanics and most people. They just didn't take the time to learn about it. What is important is that you don't try to appear knowledgeable about things which you never took the time to learn.

  394. ​ @SteveKelly1  The particle language goes back to Einstein's 1905 paper on the photoelectric effect. In that paper he gives a congenial explanation for the macroscopic photoelectric data in terms of the quantization of the electromagnetic field. But at the same time he commits his actual biggest blunder. After having identified quanta of energy, he immediately concludes in a single sentence that these quanta have to have location properties like Newtonian corpuscles. That conclusion isn't backed up by any observational detail of the photoelectric effect. It doesn't match the well known definition of energy as a system property. It's also completely unnecessary for the remainder of the paper. It's a completely unforced slip of Einstein's mind. Unfortunately other authors after Einstein have picked up this mistake and they kept building on it (to this day). What physicists mean by "a particle" is actually a quantum of energy, momentum, angular momentum and charge. Neither of these properties refers to a "small, localized object". They are all system properties. The theory does not describe particles. It describes changes in the energy of systems. You can find this clearly expressed in Heisenberg's matrix mechanics paper where initial and final energy was used as index into the matrices. That's the correct interpretation except that it's not just energy but the quad of energy/momentum/angular momentum and charges. Why these? Because these are the only locally conserved quantities in nature. Everything else changes, but these quantities get transferred from system to system. We have language for property exchanges. Energy FLOWS. It does NOT take a path. The entire concept of path makes no sense because systems are random subdivisions of nature. They don't even have to be some continuous regions of spacetime. Even in classical mechanics the energy of a spring is not localized, for instance. It's in the entire spring. The kinetic energy of an extended object is not in the center of mass of that object, either. We never had this illusion that energy etc. has to be focused in some tiny region of spacetime. That is purely an invention (and not a good one) of non-relativistic quantum mechanics. In quantum field theory it's even worse. the only well defined states are the plane waves of the (interaction) free theory. Everything else is a jumbled mess without any known physical interpretation. Whatever happens in the interaction volume can only be described with classical quantities if we look at it from infinitely far away. In other words: the closer we look, the blurrier nature gets. It doesn't get more "point-like". So, no, not only do particles not travel along paths, there simply are no particles. There are initial and final system states and they are characterized by changes in energy, momentum, angular momentum and charge. That is a fundamentally different (and 100% correct) way of looking at the world.

  396. Russia has a very effective choice here. It can, literally, do nothing. Holding Russian ground is costly to Ukraine and has next to no strategic value if Russia thinks that it can take this area back later, potentially without military conflict, if it manages to force Ukraine to capitulate. In practice it may not work like that, of course, because Ukraine could use their positions on Russian soil to position their artillery systems closer and closer to sensitive Russian targets. Getting air defense systems in there may also eliminate large safe zones for Russian aviation and the longer range HIMARS systems may even reach Moscow... or, at the very least, the outer ring of Moscow's air defense systems and other valuable military targets. On some level this seems to be a chess move designed to shorten the necessary attack distance to Russia's soft underbelly.

If you want to teach your students something useful, how about you teach them physics like the inner photoelectric effect that allows us to make solar electricity cheaper than electricity from coal fired powerplants. Or how about you teach them chemistry and why producing natural gas is much better for people above ground and below? Coal mining was a necessity in the 19th century because we couldn't do better, yet. In the 21st century it's merely an anachronism and a liability.

  411. That's the definition of the authors. A more rational person would have called this "Quantum mechanical cardboard insertion tester" because all it does is to determine if a piece of cardboard has been inserted into one of the paths of the interferometer. In technical terms the authors are comparing two different experiments with each other. In one experiment the light path is open, in the other one it is blocked. Technically that is neither classical physics nor quantum mechanics. Imagine you did this in classical mechanics e.g. by looking at the motion of a block on an inclined plane... and you calculate the problem once with an inclined plane and once without. Without the inclined plane the block simply drops down straight. Would you find that particularly interesting or strange? If not, then why is this scenario any different? We are simply comparing apples and oranges here. I think the authors were mostly confused by their own attempt to look smart.

  412. The problem with quantum fluctuations as the source of the cosmological constant is a misunderstanding of quantum fluctuations. They don't exist in the way they are being portrayed in the press. You can look up into the night sky and you can see objects that are millions of light years away (the Andromeda galaxy) with your own eyes and over 40 billion light years with instruments (the CMB). That light was not disturbed by quantum fluctuations, at all. If the universe was "grainy" or "foggy" the way the usual mental model suggests, then this light would have never made it undisturbed and we would probably not even be able to see as far as our own toes. In quantum field theory higher order terms cause changes in energy levels of bound states because these bound states select a distance (size) scale themselves, hence the integrals over contributions at higher energy are cut-off at that scale and they don't average out to zero. These, however, are not simple random terms and they all go to zero at the scale of the universe. At most you can get something like a 1/R_cosmological dependence, which would be important during inflation but can either be neglected today or would, at most, lead to an asymptotically free universe. If an actual cosmological constant exists, then it is not caused by effects that are consequences of the background geometry. It exists as part of the layer of physics that causes the background geometry, to begin with.

  419. In actual science history Copenhagen went out the window before Bohm even wrote his paper. There is no need for it in relativistic quantum field theory. Even the term "Copenhagen interpretation" seems to have been coined long after it had become more or less obsolete for fundamental physics. The reason why we still teach non-relativistic quantum mechanics to students is because the relativistic theory is mathematically extremely demanding and it is not well suited for the analysis of bound states, which occur far more frequently in the non-relativistic regime (unless one is interested in the structure of proton, neutron and pions). So it's kind of a weird ghost that just doesn't want to die, even though its time has been up since the 1930s.

  421. ​ @morphixnm  The modern measurements for that were made with radar reflection on Venus. Shapiro did those at Arecibo in the late 1960s, early 1970s. The physically relevant measurement there is the excess time delay, which is a much more precise measurement than the angular deflection can ever be. Phys Rev. Letters Vol. 26, NUM 18 has one of the papers. The max. delay was approx. 180us during the superior conjunction with error bars of approx. 20us per data point. 20us, that's a distance uncertainty of 6km or so, probably dominated by plasma interactions and a bit of topography.

If you read his actual paper, you will find a few sentences at the end where he makes exactly that remark. He already knew that his paper was useless because there was a much, much tighter bound on these correlations, which happens to be exactly what standard quantum mechanics predicts. The universe is either relativistic and then Bell is unnecessary or it's not relativistic. The latter does, of course, have catastrophic consequences for everything else in physics.

  438. @califdad4 I didn't say that one has to change the framing. That's not necessary. The problem is the OSB sheathing. Replace it with cement board and nothing will burn. Seriously. I tried it myself a dozen years ago. One can literally direct a blowtorch at cement board and the wood behind it will not burn. Actually, the other side of cement board stays cool to the touch for a minute or so while the torched side glows red hot. It's like a cheap version of space shuttle tiles. It used to be slightly more expensive than OSB but now it's actually cheaper, I believe, because wood prices have increased so much. The argument that something that is highly flammable hasn't burned in 60 years is ridiculous, by the way. Wood doesn't get less flammable with age. Many SoCal homes have a pool, by the way. That's plenty of water for an external sprinkler system. You can find videos on the internet showing just how effective it is to install a low flow sprinkler on the roof. It won't put out a fire, but it will put out embers that can start a fire. Solar is also your friend. Guess what solar panels don't do? They don't burn. They are made of glass, silicon and aluminum.

  452. Quantum mechanics is not a statistical theory. It is, however, a non-commutative solution to Kolmogorov's axioms. Statistics/probability theory is a commutative solution to the same axioms and that is the reason for a number of very strong similarities. It is a curiosum of science history that von Neumann published the non-commutative theory in his 1932 book about quantum mechanics one year before Kolmogorov published his axiomatization of probability theory in 1933.

  460.  @filosofiadetalhista  Where am I attacking you? You are trivially wrong on a number of things and I am merely pointing that out. I would suggest that you leave your hurt ego at home. It has no use in science. There is no such thing as wave function collapse. A wave function is an abstract description of a quantum mechanical ensemble (i.e. a hypothetical infinite repetition of the same experiment). Just like a probability distribution a construction that depends on an average over an infinite number of hypothetical events isn't being changed by a single actual event. Copenhagen doesn't talk about collapse anywhere. It talks about the reversible dynamics of a completely isolated unitary ensemble of one system (as described by the Schroedinger equation) and the irreversible energy exchange between the first and an ADDITIONAL second system that performs "the measurement" (that's the function of the Born Rule). The entire "collapse" language is simply nonsense that you have picked up on the internet. It is, as far as I know, not even defined in textbooks. One system IS NOT EQUAL to two systems, hence there is a need for a second formula. Reversible dynamics IS NOT EQUAL to irreversible dynamics, hence there is, again, a need for a second formula. That's why the Born rule has to exist in one form or another. From a logical perspective all of this is crystal clear. What is not obvious is why our education system does such a poor job explaining these otherwise trivial facts almost 120 years after they were first properly identified. There is an incredible amount of confusion and very little clarity about the ontological connection between reality and the theory going on, both at the layman and the professional level. That confusion has to stop. With regards to your second point... the wave function approach does not lead to ultra-precise physics. It's a remnant of the initial non-relativistic phase of quantum mechanics. It explains some trivial systems (particle in a box, hydrogen atom) with reasonable precision and completely falls apart on pretty much everything else (it's almost useless on scattering problems like in high energy physics). One can not do quantum field theory with normalized wave functions and we don't. Reality IS NOT like the non-relativistic Schroedinger equation suggests. It just happens that the step up in mathematical difficulty between the non-relativistic case that has ontological problems and the relativistic field theory case that doesn't have them is enormous. It's far too much for most students to absorb. It also doesn't buy the practitioner anything to learn a theory that has very little predictive power at low energies where effective potential theories suffice and are much, much easier to use (like in solid state physics).

  465. Visible photons are typically detected with photomultiplier tubes. Less common are bolometers. At higher energy other types of detectors can be used. There are, as far as I know, no reliable direct detection methods below microwave frequencies, one can, however, pull a few tricks from the atomic and nuclear spin spectroscopy repertoire and excite atoms (and their nuclear spins) into semi-stable excited states, which can then absorb a low energy photon (in the range of MHz or potentially even kHz), which transitions them out of the semi-stable state into one that decays rapidly by emitting a visible photon, which can then be detected with a photomultiplier, again. That's a very fun experiment that I did in university once. It's quite amazing how much "gain" a single atom can produce under the right circumstances (on the order of 9 orders of magnitude or more).

  481. That is correct. What vaccines actually do is to reduce the number of infections that turn a person into an effective vector, therefor they reduce the ability of the microorganism to multiply effectively. Ideally the disease dies out once the entire population has been vaccinated. A natural infection, however, is the very process that generates the vector, hence it enhances the ability of the microorganism to spread. What happens inside the body in either case is completely irrelevant from an epidemiological standpoint. The only question of interest is whether the organism can spread or not. With vaccination it can't, with "natural immunity" (which does not exist to begin with), it can and does.
    2
  482. ​ @OhAncientOne  Exactly. THAT is the the problem. ;-) Or, more precisely, the problem is to translate that question into an experiment or observation to which nature would give us a relevant answer. We don't have the means to perform such an experiment or observation. At least not yet.

  483.  @kaushalsuvarna5156  It tells us absolutely nothing because light doesn't take classical paths. Classical paths are an approximation. Even in classical wave theory it's the replacement of (almost straight) wave fronts by their local geometric normals that we call rays. That's a good approximation for plane waves in the free wave propagation problem. It breaks down as soon as we have interaction with surfaces that are changing rapidly at the spatial scale of the wavelength. Then we have to use the full wave theory. In quantum mechanics the validity of these approximations breaks down even further because we are never looking at just one particular system. We are always looking at all possible physical variations of the system (that's called "the quantum mechanical ensemble"). The point I was trying to make is that there is a solid mathematical reason behind all of this "weirdness", but at the end of the day it all breaks down to having to give up the wrong mental models. The world is NOT made of material objects that are flying around on Newtonian trajectories. It is made of energy flow between systems. That energy flow obeys different rules than Newtonian objects (which don't exist except as approximations) would.

You have immunity after infection for half a year, maybe a year, then your antibody count is down and the virus has mutated and you are vulnerable, again. Just how hard is that to understand?

Do you imagine that some god of literature criticism five hundred years from now will write "The best author of the 21st century was X. X had exactly three readers, including himself.". That isn't going to happen. Shakespeare is still popular because he has gone through many transformations by many directors and actors. Peter Greenaway's movie based on The Tempest is just as enjoyable as the original. That's because Shakespeare talks to US. He doesn't talk to himself. He has opened his material to interpretation by others. He wasn't afraid to fail by showing it to people who were going to criticize it and change it, if appropriate. OK, I admit, that takes some serious stones.

  511.  @eljcd  The initial calculation by Feynman? It is not naive. It's actually quite congenial and it works, with some difficulties. What is certain is that we haven't found anything better for over 70 years, which tells us that it's not all bad. Is it the best possible model for how quantum fields work? Certainly not. I am highly skeptical that the real/virtual particle picture is the best way to describe quantum fields myself. That, however, has absolutely nothing to do with the multiverse question. QFT tells us how to calculate with quantum fields and which kinds of quantum fields can exist, at all, but it does not tell us which kinds of quantum fields should actually exist. I am not aware that there were a whole lot of complaints about that in the past. If we were to put the same "prediction" criteria for the universe on plain QFT that we are putting on string theory, then we would have to conclude that it predicts an infinite number of possible universes. Instead we accept that it can't predict any. It can only describe the one we see. What happened with the introduction of string theory is that people had overblown hopes that it would reduce the number of possible quantum field theories to one. It didn't do that. It seemingly reduced it to a very, very large number. Unfortunately, so far nobody seems to have found the actual solution to the universe inside string theory, either. It may be in there, it may not be. And with that a serious philosophical mistake crept into the discussion: since string theory (which effectively has done nothing for physics proper so far) predicts a very large number of possible low energy universes, then maybe there have to be a large number of low energy universes. That is total nonsense, of course. The situation on the ground has simply not changed: we can describe the low energy universe very well, but we still can't predict it. We are still roughly where we were in the 1970s, when the SM was more or less finalized structurally. That is not a very long stretch of stagnation in physics. It was much worse in the 19th century when we had a more or less spotless (if inaccurate) theory of motion of matter without having any theory of matter, at all. So take the "discussion" with a grain of salt. It is far more about egos of different groups of people, neither of whom has a solution, than it is about the actual state of physics. Physics is just fine, it simply didn't make as much progress as some elderly physicist would like to have seen. Will Susskind be able to die in peace, having seen the holy land at least from afar? No. He can talk to Moses and Newton and Einstein about that experience when he gets to heaven. :-)

  512.  @eljcd  I think there are a number of attempts to use more or less plain QFT to work around the gravity problem. There is the double copy group which says that basically two copies of the color force can produce gravity. I have yet to understand how that is supposed to work even even at the kindergarten level, so I can't comment. Then there is an attempt at making gravity a massive field, which could possibly explain dark energy, but the model seems to suffer from cosmological stability problems... quantum gravity seems a bit like playing Whack-a-mole, whenever a model is successful in one area, it has serious, if not deadly problems in another. My perspective as an experimentalist is a bit more focused on observations, right now. I don't believe that we will get the funding/develop technology to get beyond the 1TeV accelerator barrier within my remaining lifetime. So that leaves astronomical and cosmological observations. If you have been watching the success of gravitational wave astronomy and radio astronomy to image black holes, then it becomes somewhat evident that building new (space based?) observatories for gravitational, optical and radio-astronomy is the way to go. Nature has given us such a beautiful laboratory of absolutely monstrous extreme systems in the universe. We can never hope to replicate the conditions near and inside those objects in the lab, but we can harvest much of this information from a distance. That is where the near term progress of physics lies, IMHO.

  516. I like entropic gravity, too, but Verlinde doesn't seem to have made a whole lot of progress with the idea after the original publication. It's a cute bunny until one puts it under the microscope and then it seems to come with a lot of fleas that are not easy to get rid off, either. MOND and its different variations are not much better, of course. I would go with Einstein for now plus something else that we just don't know. That's the safe bet.

They were meant to illuminate "reality" aspects of quantum mechanics. As such they basically just confirm what we have already known about QM since 1927: outcomes are NOT compatible with classical objects with classical state that are moving along classical paths. That some people were misrepresenting the facts about these experiments to make a quick buck with trolling on the internet and that the YouTube algorithm is helping them to do that is a problem YouTube has to deal with. It's not a problem of physics proper.

  539.  @Franksmoney  You were asking how to apply OOP in the real world. That is what OOP is good for: it produces documentation about the structure of the software. All of the class stuff is being stripped out by the compiler, anyway, to produce a flat executable. In C++ it was stripped out before the compilation, actually. That's what the pre-processor does (or did in the initial implementation). Secondly OOP takes a Turing-complete language and reduces it to an incomplete language. This is done to reduce programming errors, but it's doubtful that it actually does that. The real effect is that you, the application programmer, are being limited to whatever the architect decides to be "allowed". I hope this is not the first time that you are hearing this trivial stuff about OOP that nobody wants to tell you. ;-)

I have NEVER met anybody without a degree on the job.

  546. If it allows them to calculate the low energy string spectrum, then yes. It does not necessarily lead to a practical result because of the string landscape. Unless it allows us to pick one specific version of the theory out of the 10^500 (or whatever) possible ones, the spectrum is still not uniquely determined. That problem will most likely not go away anymore than the equivalent problem in quantum field theory. Why is the low energy spectrum in QFT U(1)xSU(2)xSU(3) and not something else? We don't know. Well, actually, it's not even that if you are precise. You, as in your body, are a peak in the low energy spectrum of QFT. So is a water molecule, a goat, third avenue in New York and the star Beta Orionis. "Every possible thing" in physics is such a peak. We aren't calculating any of these solutions from first principles. We are happy to stop at the em field, electrons, muons, neutrinos, quarks etc., so we are basically cutting ourselves off at one massless and one solution that is a fraction of an eV (the neutrinos). And technically we can't calculate the locations of any of these peaks in QFT, either. We a simply fitting measurements to them. So it's not like that string theory can't so something that QFT can. They are pretty much equally "powerless" at the moment, it just gets misrepresented in the public discussion. (And no, I don't think string theory is the correct approach, either, I am just trying to qualify a little better what "theory" means in this sector.).

  547.  @Spiderboydk  That is true, but thankfully I don't have to care about that. I care more about memory layout and this lets me retain full control. The technique is very useful in embedded system projects where memory is often a serious concern. Like I said, I would not recommend it for teams and large software projects. Having said that, I am not sure how much the average software engineer actually knows and cares about effects like cache misses. My feeling is that they know little and don't care at all.

  548. Yes, it so good that you can buy these under the name "cable pulser" commercially. I had a very old one a long time ago. I think it used a mercury switch. It made extremely clean sub-ns risetime pulses. Pulse length was controlled by attaching your own transmission line externally. If you wanted longer pulses, you just put a longer cable on. :-)

Neither man nor machine can beat mathematics.

  562. Technically the Nobel Prize doesn't work for physics, either. Nobel wanted it to be given for discoveries of value to the human race... and few relevant physics discoveries are falling in that category. Einstein didn't get it for the discovery of relativity, even though that is the centerpiece of physics. He got it for the explanation of the photoelectric effect, which is of enormous economic importance in form of solar energy (but they could not and did not know that back then)... but Einstein didn't discover it. He merely explained how it works.

  584. You still have "deflation" in the tech sector. The price per pixel on large screen tvs and the price per display area are still dropping nearly exponentially. That's not deflation, though. That's technological progress. In reality the price for many commodities, when adjusted for inflation, is nearly flat. The price of sand and gravel for construction, for instance, has stayed within a 20% band in the last 50 years or so, if I am not mistaken. That won't change, unless somebody invents an anti-gravity drone that can ship tons of bulk material directly from the quarry to your construction site.

  626. Not quite. The holographic idea is based on a mathematical equivalence, however there is a physical equivalence that is very similar and that is well known to all of us: what we are seeing are surfaces. There is a one to one correspondence between the image of a surface in our eyes and the light that is being reflected by a surface if and only if the space between the surface and our eyes is empty. One can use this to construct physical holograms that seem to show three dimensional scenes using a flat piece of holographic film. The reason why this works is because there never was any three dimensional information to begin with. The surfaces we were looking at were always two dimensional, they were just not flat. The hologram encodes this "non-flatness" in addition to the reflectivity of the surfaces. The idea behind the holographic principle is similar, it just uses more complicated "surfaces" and "images of surfaces", but it works for the same reason: there is effectively less physical information in a three dimensional volume than there seems to be.

Our schools are set up to get children to think logically, but the problem is that many children simply can't do that. They are, most likely genetically, predominantly right-brained individuals. In such people emotions can easily override logical thinking. These children are not doing well in school when it comes to science and mathematics, which creates an educational trauma. In adults that trauma manifests in different ways, from indifference towards science all the way to denialism.

  632.  @lurkmoar9066  I am afraid of people who can't think straight. They are dangerous. ;-)
    2
  633. Physics is all about reality. We simply compartmentalize reality into smaller, easier to describe pieces. That's why we are the most successful intellectual discipline of all times. ;-)
    2
  634. ​ @moskitoh2651 My first theoretical physics teacher said this in the first few minutes of the first lecture: "Gentlemen. Physics is the art of approximation. Those of you who are not comfortable with the fact that physics uses increasingly more refined and accurate models of reality should leave this lecture now. The philosophy department is across campus. There you will learn the absolute truths about the universe... and they will all be completely false.". Big laughs, nobody got up to become a philosopher. You would, obviously, have been the exception. If you are looking for absolutes, that's philosophy and religion. Both are absolute bullshit. ;-)
    2
  635. Congrats. You are one in thousands who actually understands what is really going in.
    2
  636. There is no need to. We don't care about infections. We care about hospitalizations and deaths.
    2
  637. What you don't know is that the Obama administration is most likely responsible for Russia being blind on the battlefield, right now. They just made nice with Russia, but behind everyone's back they sabotaged the Russian space capabilities to the point where almost none are left. Putin was very upset about that from what I have seen. :-)
    2
  638. If a conversation gets boring that means one of you isn't into it or both of you are losers. Cut your losses and end it right there. ;-)
    2
  639. Like when they told you that you failed to earn your high school diploma? That wasn't misinformation by the government. You simply didn't pass. ;-)
    2
  640. Look, Ma! There is the guy who can do dumb stuff while he does literally nothing. ;-)
    2
  641. There are no viable consumers in North Korea. North Korea is a third world country suffering from famine. It would be a major economic drag on South Korea for decades to come. We have lessons from the German reunification which was economically much less of a problem because of the relatively smaller population size of East Germany.
    2
  642. A photon is a little bit of energy. Asking for its size is like asking "How big is a kWh?". If the latter doesn't make sense to you (and I hope that it doesn't), then asking for the size of a photon does not make sense, either.
    2
  643.  @waynelast1685  A visible photon is a few eV in energy. So, if that energy has a size, then how big is a kWh? :-)
    2
  644.  @waynelast1685  I know exactly what you are thinking. :-)
    2
  645.  @waynelast1685  I wasn't wasting your time. I made it pretty clear that I think that you are nothing but a poorly performing troll, didn't I? :-)
    2
  646.  @waynelast1685 See my first post. :-)
    2
  647. Yes, it's about half as expensive as Uranium and the cost of Uranium is completely irrelevant for any of the current reactors.
    2
  648. All you need to know is that we don't have inflation, right now. We have a serious supply-demand problem. A lot of people walked away from their jobs and some goods are simply not available because they take a long time to produce (like semiconductors). The response of the major economic players will be more automation, to become less dependent on the workforce.
    2
  649. This is all very cool, but where is the genetic data to back this up? If up to a quarter of the Roman population even in Britain was of African origin, then it should have left plenty of genetic markers.
    2
  650.  @UICeinnselaig  Then I would call the evidence rather thin.
    2
  651. Because a measurement is an irreversible energy transfer and an ideal beam splitter is reversible. A real beam splitter does absorb a little energy (because it has finite mass), but in practice that's very hard to measure and for most cases irrelevant.
    2
  652. It doesn't. Tidal forces can not be eliminated by freefall.
    2
  653. I am tired of your eternal pointless complaining as well. I think we are even. ;-)
    2
  654. You bought and read a book... sound of one hand clapping. ;-)
    2
  655. No serious designer would make human ureters so narrow that kidney stones could get stuck in them. Such a design would never pass the plumbing department's minimal technical requirements. ;-)
    2
  656. There is no massive loss of jobs. There is a massive undersupply of labor force, right now. The Great Depression was caused by a failed monetary policy that was exactly the opposite of what we are doing today. It simply can't happen again. Kitty, you need to stop being a fearful individual who repeats all the stupid hearsay on the internet. It doesn't work for you and it doesn't make the internet better, either, to have people like you repeat all this bullshit endlessly.
    2
  657. There is no evidence of our technological civilization in terms of radio emissions, either. People simply don't understand that a radio station that was meant to broadcast a couple hundred miles, at most, doesn't reach very far against the background noise of the solar system (emissions from the sun and plasma). It doesn't matter how big the antennas are. The signal to noise ratio is just not there. We have gone ever more radio-silent since the invention of the internet, anyway. Almost all of our RF communications are now low power directional links that barely reach beyond ten miles. The only way to communicate to another star system is by actively building the necessary transmitter and receiver infrastructure, which we haven't done, yet.
    2
  658.  @Lia-zw1ls7tz7o  Yes, the signals will reach the entire accessible universe, eventually, but they are too weak compared to the radio emissions of the sun and the plasma surrounding us. That's a lot of background noise. Imagine you want to talk from one end of a football stadium to the other with tens of thousands of people shouting. That won't work, either. The only way to achieve communication is by building strongly directional transmitter and receiver antennas.
    2
  659. Knowledge is neither finite nor infinite. It's simply hard work. We call those who are not willing to do that hard work "intellectually lazy". ;-)
    2
  660. They probably had fifteen minutes to half an hour of advance notice. Cruise missiles don't fly very fast (these ones are subsonic, so the "travel times" are similar to those of passenger jets). The real embarrassment is that they didn't clear the building and got everybody into the bunker. They were simply completely full of themselves. ;-)
    2
  661. Yeah, but Elon Musk is special. He made billionaire. No real scientist has ever achieved that. They do, on average, get into lower middle class.

  662. I am pretty sure Cuba would love to have Wolff as a permanent resident. Curiously... he's not leaving. Somebody should ask him why.

  663. A creationist is a chess playing pigeon. You can never get through.
    2
  664. I very much doubt Hitler and Stalin were seeing themselves as implementing Hegel's ideas. They were simply installing themselves as dictators.
    2
  665. Yes, that's complete bullshit. ;-)
    2
  666. Tesla lawyers probably had a nice chat with Rivian lawyers and resolved the licensing issues peacefully.
    2
  667. Ah, so you don't understand the climate problem, either, but you felt strongly that you needed to leave a nonsensical comment about it. Well, it is the internet, after all. :-)
    2
  668.  @farrier2708  Yes, responding with a lengthy logical argument to an average internet troll's bullshit would be far more nonsensical. :-)
    2
  669.  @farrier2708  Exactly. Pointing out that you are talking bullshit is all I am going to do. :-)
    2
  670.  @anteeko  Intellectually speaking it would be so much better for you if you were just an attention troll than if you actually believed that bullshit. ;-)

  671. All teens are arguing with their dads and they always take the opposite opinion. Sound of one hand clapping. ;-)

  672. Chances of DK effect are rising exponentially the further a person is straying from her area of expertise. Sabine Hossenfelder needs to be careful here.
    2
  673. That sounds about right, but please have your keyboard fixed.
    2
  674.  @anywallsocket  I thought we are talking about fundamental physics? The most fundamental physics we have right now is QFT. QFT tells you from first principles what can be measured "exactly" and it ain't much: scattering amplitudes. That's it. Everything else is an approximation based on semi-classical averages. Now, if you want to put philosophical bullshit on top of, that's fine with me. I will simply call it philosophical bullshit and move on.
    2
  675. Look, Ma! FUD at its finest. ;-)
    2
  676.  @Larkinchance  All I am saying is that you either didn't have proper math education in school or you weren't paying attention. Math is NOT the same as computation. I have not calculated a single sine or cosine to six decimals in my entire life by hand and I am physics PhD. I know what sine and cosine functions are good for but I leave their calculation to my CPUs.

  677. Less alcohol will help. ;-)

  678. Or... you could have read the Python documentation. Oh, wait, you are a real engineer, right? The kind that doesn't read the frelling manuals but rather gets second hand information on YouTube. ;-)
    2
  679. Exactly. That's a good example for a free will algorithm that can not have a predetermined outcome that depends on our mind. Unless someone is a solipsist, of course. In that case the coin is just a figment of our imagination and it shows whatever side we have (unconsciously) chosen, already. Now we are in the deep end of human psyche, though.

  680. Europe is a match for Putin but it will probably have to engage actively in the war eventually. There is only so much in weapons systems that Europe can donate, right now.

  684. Calm down.
    2
  685. We can imagine a lot, but reality will be much more mundane. Absolutely nothing interesting will show up.

  687. I hope you are not betting, your picks are awful. ;-)

  688. Not at a real company. You won't even survive the first round of interviews with that attitude.
    2
  689.  @theoutlet9300  Since I am my own single developer (hardware engineer, test engineer, mechanical engineer, assembler, sales person and tech support) I try to catch all bugs before I ship the product to the end user... I can't afford product recalls. ;-) I wasn't talking about bugs but about attitude. If you try to offload buggy code to your fellow developers, you will pay a hefty price. At the very least all of you will have to work even more unpaid overtime.

  690. Yes, we noticed that the Russians can't hide. So did the Russians. ;-)

  693. Those machines were safer with holes in them than the Russian product is fresh from the factory. ;-)
    2
  694. The least useful theory is the theory of everything. I don't know why people are so desperate for it. Most people are not even willing to learn the properties of the most trivial theories like Newtonian mechanics. What use would a ToE be for them????
    2
  695. Even that only works if you know the computer architecture better than the compiler does, which is true for approx. 0.01% of software developers.

  697. Most billionaires seem to care about one thing only: how to make another billion. They don't give a frell about politics.
    2
  698. The detector detects a quantum of energy, not a particle. If there is not enough energy in the field, then the detector can not detect anything. However, emission and absorption processes are all quantized, so one can never emit "less" energy than can be detected.
    2
  699. Academia hasn't been toxic towards women for a long time and even if that was so, it's not the reason why Sabine Hossenfelder lack success in physics. She is just not good enough. You can easily see that by reading her publications.
    2
  700. Apart from the fact that this isn't science but just math, you check for self-consistence. Twistor theory does not seem to lead to physical theories, at least not in a naive version.

  701. Ukraine doesn't need soldiers. They have more than enough. It needs more weapons systems.

  708. There is a school of thought that suggests that the single best thing you can do for your software quality is to get rid of the architect. On can even find very rational reasons for that idea. The major argument is that an architect is not god. He or she can't predict the future, but by locking you into the architect's initial (and most likely false) solution for the unexplored problem you are preventing your coders to modify their approach as the really crucial elements of the task are being discovered during actual software development. Being open to change is generally better than having planned everything (the wrong way) right at the beginning. It's the same problem with socialism and capitalism. Socialism is theoretically better because it starts with a grand plan, but in reality capitalism outperforms vastly because it's not locked into the false grand plans.

  713. Why are you threatening people who don't care about you? ;-)

  714. In many countries in Europe higher education is free or almost free. If you can afford the cost of housing, food and books, then you can spend the 4-12 years that it takes to get a degree of higher learning. I have. It was totally worth it.
    2
  715.  @mac_mcleod  I know. It's ridiculous. A nation depends on the best of its best. That means we have to try and get everybody to be the best they can be, not just in K-12 but also beyond. To load that with an almost impossible financial cost is self-destructive behavior.
    2
  716. Science is always looking for the unexpected. The problem in high energy physics is that most of what pops up these days is not. The last really unexpected finding were neutrino masses.

  720. Awh, you are so cute when you are begging for attention. ;-)
    2
  721. Tacitus writes: "Christus, from whom the name had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus...". He clearly uses Christus as the name of a person, not as a title. What's your point? Tacitus may not have known the name of Jesus, but he clearly accepted the historicity of the person. Is that proof of something? Yes, it is proof that Tacitus accepted the historicity of a Jesus/Christ person. That is all it is proof of. It tells us exactly nothing about Jesus.
    2
  722. So basically you are the most antisocial person at work. :-)
    2
  723. The problem with these explanations is that they are focusing on the wrong scenario. There is no non-causal behavior in the rest system of the two endpoints A and B or the ship S that traverses the distance between them at v>c. The problem occurs when an external observer tries to establish causality from a rest system that moves at a non-zero velocity relative to A and B. FTL brakes the causal consistency conditions, i.e. an outside observer could see you being alive before your grandfather was and they could see the timeline between the two of you running backwards.

  724. Which religion? We invented so many... one more stupid than the next.

  726. What do you not like about what he is saying, exactly? Please be precise.

  727. Functional programming is when you can't read your own program 45 seconds after you wrote it. Object oriented programming is when your programming style is driven by hype rather than by actual problem analysis.

  728.  @ggzibugg  Neoliberalism is not anti-science. Neoliberal business people know exactly that they can't operate without academics. What you are seeing here is not neoliberalism. It's not even fascism. The Nazis were absolutely enamored with science and technology. They just didn't like the fact that Jewish scientists were the leaders in their fields.

  731.  @pauladamson9459  You are welcome.
    2
  732.  @Neehize  Yes, it is. The impedance of the cable is in the range of maybe 150-200Ohms. The load is maybe 1Ohm. That means the actually interesting physics (pulse propagation along a transmission line) is hidden from the casual observer. What does that tell you? It tells you that Veritasium is not good at either physics or electrical engineering. :-)
    2
  733.  @marijnvangeest  We don't need any electrons to make electrical energy flow. That's why we have wireless communications. That's what light does. It's the physical vacuum that transfers the energy. What the electrons do is to "tell" the physical vacuum where it should transfer the energy to. They form the boundary conditions for the energy flow. That a few electrons are flowing along the wire is just a side effect. In the case of AC they aren't even doing that. See transformers... there is no physical connection between the primary and the secondary coils.

  736. He could move to a much smaller house if he wanted to make an actual difference.
    2
  737. There is no such thing as a gravitational force to begin with and forces in quantum mechanics are not "fuzzy". The evolution of the quantum mechanical ensemble is completely smooth, even though special relativity forces the individual system to exchange energy, momentum, angular momentum and charges in discrete quantities, which in a certain semi-classical limit would make reality feel "shaky", but that's a problem with the special choice of that limit.
    2
  738. He is mostly saying that he doesn't understand quantum mechanics. :-)
    2
  739. It does not break down like that. Atoms and "particles" are mesoscopic effects. The only fundamental physics consists of reversible and irreversible energy, momentum, angular momentum and charge exchanges. These are changes in properties of systems, not atomistic constituents.

  741. WuXi is, at best, a medium size biotech company. It's a supplier of biologics and services. That's nowhere close to the big bucks that the large pharmaceutical companies are making. There is nothing to beat here.
    2
  742. ​ @pettypractice7872  What about "It's a supplier of biologics and services." did you not understand just now? The point I was making is that WuXi is NOT a competition to the large American companies and it is not even a competition to small biotechs, either. If you want to be specific about CDMOs, then WuXi still ranges behind Samsung Biologics and Lonza. Is the p*ing match over now? ;-)
    2
  743. You sound jealous. :-)

  744. There is nothing interesting about MWI. Everett simply didn't understand what quantum mechanics is. He mistook the (admittedly misleading language) for gospel and created a piece of poetry in motion.

    2
  748. Yes, Chris, there are a lot of better looking internet trolls than you. ;-)
    2
  749. Because that's the "natural motion" in general relativity. With gravity the simple rectangular coordinate grid of your teenage years goes out the window and you have to learn some fairly heavy math called "differential geometry" to catch up with reality. Nature really didn't make this one easy for us. Not one bit.
    2
  750.  @keppela1  Physics is a description of observed reality. What we observe is that without gravitating bodies close by two objects are moving in a linear fashion relative to each other (as long as there are no forces acting between them). With a gravitating body they don't even do that. That's it. That's "all" physics has to describe. If that's not enough for you I can only offer you poetry, philosophy or religion as outlets. Science doesn't care about anything else but the description of the linear (without gravity) and non-linear (with gravity) motion. But since I am neither in the literature, philosophy or the theology departments I can't tell you what those other guys will be saying about the situation. Physics, OTOH, got its part all covered with Einstein's equations. ;-)
    2
  751.  @keppela1  Yes, you can look out the window and you will get a totally wrong impression about the world. Don't worry. That's pretty much what happened to everybody before physicists figured out how it really works. That's why we are the smartest of the smart, after all. :-)
    2

    2
  763.  @HealthyDev  I did it only once... while I was looking for a new job. The project I was on wasn't even bad and neither were the colleagues or the boss, but I had personal reasons. My next company was like family. I loved it there. I have heard horror stories, though, from someone who was in a large company that is best known for its databases. The restrooms seem to have been crowded. :-)

  764. No.

  765. You should talk to my eight antivaxxer relatives who had COVID-19 for the second time, already. They were all sick for two weeks, again. They didn't have "mild symptoms", either, neither the first nor the second time. And then there is the couple that had it for the third time... he has long COVID-19 symptoms in addition. So much for "natural immunity". Immunity after infection lasts until the antibody counts are too low to protect you. It's that simple.
    2
  766.  @Frillar  This is not "anecdotal" to the folks I know. To them it is dead serious. Either way, as long as people get re-infected, the disease stays around. We have countries where it has already claimed one in two hundred lives. When is enough? One in a hundred? One in fifty? One in ten? What, exactly, are you waiting for? A miracle? God's angels appearing in the sky and inoculating people with god-rays? How did that work out for leprosy and smallpox? Those were cured by us. Smallpox was completely eradicated.

  767. No, it isn't true because the electric force depends on an electric charge, which is not related to mass.

  777. Light is a quantum mechanical phenomenon, so you are doing QM here whether you like it or not. It just happens that the uncertainty principle has nothing to do with quantum mechanics. It's a general property of functions and linear operators, no matter what they are describing. Something like a Gaussian does, of course, have a unique parametrization and we can define "the center" in a unique way. That is simply not the case for arbitrary functions. Where is the center of a plane wave, for instance? The entire notion of it having a beginning, a center and an end is useless. What's the physical meaning of the center of a hollow sphere? There is no physical interaction at "the center", it's empty. All the physical interaction would be with the shell, even in classical physics. One simply has to learn to live with the fact that "center of mass" is a very, very limited concept for a very limited class of problems, classical or not.

  780. Complex numbers in quantum mechanics represent rotations. Of course we can represent rotations without complex numbers. Matrices work just fine. The paper is complete nonsense, anyway. We know where rotations and hence complex numbers come into play from first principles. The entire structure of quantum mechanics can be derived from a few trivial axioms with like half a dozen pages of high school level math and has been repeatedly by several authors over the years. The papers in which this was done are about as interesting as watching paint dry.

  788. There is nothing to put back. Manufacturing is a mere 15% of GDP in the EU. In developed countries manufacturing always becomes an afterthought, economically speaking. In China it's still 28% and falling. By the time China catches up (40 years from now), its manufacturing sector will probably also end up being in the low teens. That's just how it goes.

You need to stop the binge drinking. ;-) Why does the pattern form with ensembles of independent quanta? Because the slit is always the same. It's the matter of the slit that provides the necessary "memory". Did I say that you have to stop the binge drinking? Look what it's doing to your brain, Dude! You have no analytic abilities left. :-)

  805. Neither quantum mechanics nor relativity seem to be approximations. If we break relativity, then all of physics collapses. Quantum mechanics, at the end of the day, is a local consequence of relativity, so one can't even say that one is wrong if the other is correct. What is not clear is what remains of "global" physics because relativity PLUS the equivalence principle are causing some major havoc on ideas like "energy" and "angular momentum" and not just in the quantum sector.

  814. No, she doesn't. The trouble with MWI is so large that somebody has collected a list of like 60 major arguments against it, if I remember correctly. It doesn't matter, though. MWI is both physical and philosophical bullshit made up by a failed physicist and popularized by people who know that bullshit sells better than reality. It is really pointless to waste any time on it. What really matters is that people understand why Copenhagen, which is being decried as "incomplete" and worse is actually the physically correct description... within its very limited range of applicability (non-relativistic quantum mechanics is not a good theory and we should really not be teaching it as if it was). I think you will see a change in physics education, both at the high school and the university levels, that will correct the 19th century misconceptions that are still being taught. Be the end of the 21st century every kid will be given the tools to understand 20th century physics. :-)

  825. It simply means that there is an irreducible amount of angular momentum that comes from the measurement systems. No matter how we interpret the process, it does not result in a "classical" view that quanta are "objects" that carry all their properties with them. Of course quanta were never supposed to be objects in the first place. That's was always a misunderstanding of nature.

  827.  @Muhahahahaz  I have a felling that might be the catch. The verification of that process might be harder than the original proof. Maybe my intuition here is wrong, but the constructions seems to classify all theorems and proofs into an infinite set of equivalence classes. What we are given is the equivalence class but not which particular proof in that class it is. Since the number of proofs in each equivalence class is infinite, knowing the class is useless.

  848. @ During most of the Indian Wars (certainly a euphemism), the word "terrorism" was actually used for "state terror", so the terrorist would have been the US government. One could argue that both sides engaged in massacres that did not spare civilians, women and children. One could also ask native Americans the obvious questions: "How did that war work out for you?" and "How's life on the reservation?". The Palestinians may want to listen to the answers and maybe even learn from them.
    2
  849. @ If the Palestinians are trying to tough it out in Gaza there might not be any Palestinians left in Gaza, either. Something to think about. But then what am I saying? Thinking and Palestinian doesn't really fit into a sane sentence.
    2
  850.  @Jiggly_WigglyPuff  Except that that's not how quantum mechanics works at all. The only thing in superposition is an abstract called "the wave function" and whether it's in superposition or not is simply a matter of choice of base functions. The same wave function can be in a pure state with regards to one base and it will be in a superposition of states with regards to other bases. The entire mental construction of "superposition" as a physical effect is completely false.
    2
  851. It's more than just education. I have a PhD in physics but I am far from being middle class. My parents started with literally NOTHING and so all I ever had was my education. Since I didn't care about working in the financial industries or similar high income positions, I had to make do with fairly mediocre salaries all my life. That's OK if you don't have children as you say and you don't want to leave them a better life than you had. Then you can be flexible and just enjoy, like I did, without running after the money. If you want more than that, then you have to go where the money is and do whatever it takes. Will it result in happiness? Not for the people I know who went that way. They have more money than I do, but I don't particularly envy them because I know how much they had to work for it.

    2
  855. Because JWST development began in 1996 and Elon Musk didn't start SpaceX until 2002. If they wanted to achieve the same science goals today, they would plan for launch on a Starship and the design would be completely different, have a much lower complexity and a much lower risk and cost. It would probably look a lot more like a supersized Hubble.
    2
  856.  @polymathpark  “Prediction is very difficult, especially if it's about the future!”. Having said that, I would agree that the JWST is a typical product of the less healthy side of government/private industry relations. It is congress spending money for spending's sake rather than as a result of careful deliberations. It has taken a lot of money away from other science programs that would probably have been just as, if not more important. That's just my two cents.

  857. Yes, that was a lot of bullshit. ;-)

    2
  864.  @TroyIII  You don't "change the momentum of a particle" because there are no particles. Quanta are small amounts of energy, momentum, angular momentum and charges that physical systems exchange between each other. They are properties, not things. In the phrase "red car" the word "car" represents an object, while "red" represents a property of that object. "quantum" is like "red". It's not like "car".

  904. It's never l/c. This is a transmission line problem. What really happens is that there is an instantaneous current flow that is V/Z_tl, where Z_tl is the transmission line impedance of roughly100-200Ohm. That will, of course, not light up a 1Ohm light bulb, but it is still the zeroth order effect. As the electric field spreads along the transmission line, the Ohmic and skin effect losses will increase until, after only a few kilometers, these losses effectively take up all of the energy that we are pumping into the line. It is entirely irrelevant how long this thing goes on after that initial lossy section.

  912. The will of Nobel states that the price shall go to those who made the greatest positive impact on mankind during the previous year. It's very hard to argue that the general theory of relativity made any impact on the lives of people in 1915. It does now through the GPS system, but that wasn't invented by Einstein.
    2
  913. You mean everybody who wants to make nuclear weapons on the cheap? Sure, what could go wrong? ;-)
    2
  914. That's kind of doubtful at this point. It looks more like the Chinese economy is having a hard time making the transition from concrete and steel to higher end goods. This is not unique to the Chinese experience, of course. It happened in Europe and the US with serious social disruption that still reverberates. China's problem is, of course, almost an order of magnitude larger. Xi simply doesn't know how to wind these industries down, so he artificially props them up. That's a poor bet. Economics always wins, no matter how desperately the government tries to fight it.
    2

    2
  918. Let's put it this way, it doesn't take much to have systems that satisfy reasonable criteria for life like the ability to reproduce and to adapt to environmental changes. Some of the classical criteria like "metabolism" are trivially dictated by thermodynamics anyway. Adaptation and, slightly more specific, homeostasis are basically already satisfied by something as trivial as a chemical buffer system, so it's not like we are defining life as something overly complex to begin with.
    2
  919.  @elormyaw6183  These are also the wrong definitions, because what is alive is not a human being or a tree. It takes the entire planet to form life and to sustain life and it takes the entire universe to make the planet. The true "requirements" are much, much more stringent than what the biologists are usually talking about. The universe is simply capable of high levels of local organization. Biological life is most likely just one of these emergent local phenomena.
    2
  920. Thousands of unvaccinated people are dying of COVID-19 right now because Q and Trump told them that fish tank cleaner and horse-dewormer are the medicines to take and the vaccines are poisonous.

  931.  @christianlibertarian5488  No offense, but the people driving Cadillacs and Lincolns were always low class with more money than taste and today you see mostly the (really) elderly in those ships. And then there are certain gold chained ornamented "musicians" who are "expressing" themselves through that car sub-culture, probably because trucks are already taken by another class of "hard working white", coal-rolling, folk music listening folks with indoor sunburn. I know... it's such a cliche... until you watch the "which rifle is the best for you" and the "gangsta with 50lbs of fake gold chain" videos on YouTube and you realize that there are seriously Americans who find either of that nonsense "cool". The elderly lady who drives that 20 foot long faded brown car from the past when 25 cents would buy you a tank full of gas and a streak dinner lives in the corner apartment on the floor above mine. :-)

No offense, but did all of you stop growing intellectually in kindergarten? I mean we can agree that they couldn't know the reason why the universe isn't deterministic (because of relativity) in the 18th and 19th centuries when this concept was the color of the season, but that it was always a horrible color is trivial to spot, isn't it? ;-)

  943. No, they can't pass the bar. If you try to get any information about science from any current AI you will discover very serious problems very easily... assuming that you know the correct answers. Where it gets way worse is in areas in which there are no known correct answers, like economics. I just ran a search for economics data on catalytic converter sales. Not only did Google return way too many "industry reports" (there are not that many reputable companies that have the analysts who can write such reports), but the sales numbers varied widely and almost all of these reports (ostensibly written in 2024!) were predicting catalytic converter market growth of 7-15% annually! Can you tell me how the catalytic converter market can grow so rapidly in a world that is switching over to electric cars? No, of course not. That's all just AI making these numbers up after having been trained on reports from past years and decades during which the catalytic converter market was growing rapidly. The AIs can, however, not identify the actual economic realities of EV sales.

  949. The linker will tell you. It's a bit more complicated than that, of course, because not every program on a multi-tasking machine can have the same memory sections mapped to the same hardware address, so what the linker actually tells you is a symbolic address that merely points to the entry in the memory management unit, which then translates that to the physical hardware address that the CPU puts onto the address bus. Even that is a multi-stage process on modern CPUs because the L1 and L2 caches are still between your program and the actual memory. So instead of grabbing the data from the main memory, the machine will try to get it from L1 first, if that fails from L2 and if that fails it will reload the caches from the main memory. Word to the wise: you really, really, really don't want that to happen because your 5.3GHz racer then basically falls back to the speed of an 80 MHz CPU or so... because the CAS latency on DDR4 is still on the order of 12.5ns! I used to have faster (but much, much smaller) memory than that on one of my boards in 1995... so we have been basically standing still with regards to board level memory access times for like 30 years now. Chip level memory is orders of magnitude faster now, of course, so try to write your program in such a way that it doesn't jump around in memory too much so that the multi-level caching strategy can actually perform its miracles.

  970. The proper experiment to study the question whether spin projections (not spin) are intrinsic properties are multiple Stern-Gerlach magnets in series that are rotated by 90 degrees relative to the previous one. Such a setup will split one beam in two, then four, then eight etc.. No matter how many times we are performing the experiment, each beam will split again and again and again. We can therefore only conclude that there is no intrinsic spin projection property that is being carried around OR that each quantum has known since the beginning of the universe which of the exponentially many pathways it would take. The latter nonsense is known as "superdeterminism" and it's completely unnecessary.

  973. The only physics courses worth going to in college\university are those for physicists. Forget about "Physics 101 for x", where x is in {engineers, mathematicians, chemists, egyptologists, dentists, podiatrists, pre-school teachers,...}. I had desperate students from other faculties come to me because they couldn't understand the material. They showed it to me... and I couldn't understand it THAT WAY, either. Physics can not be abbreviated. There is a reason why physicists take an entire semester just for something fairly straight forward like classical mechanics... and in reality it would have to be two to get to any substantial level. So, yeah, it's not "you". It's the way they are trying to teach it to you.

We won't be of any real interest to "them" until we try to leave whatever space has been assigned to us. If we know one thing, then it's that "property rights" are an extremely sensitive matter. We don't have any reason to believe that this changes at the galactic scale. Right now we are living in the nursery. Eventually we will move into the children's bedroom. We will even leave the house. The neighbor won't make himself known, though, until we try to enter his lot... and that's when "they" will tell us that we are overstepping our boundaries. It will, hopefully, come in form of a diplomatic invitation rather than a warning... but it will come.

  982.  @tTtt-ho3tq  Of course it does. One can derive special relativity in a couple of pages of K-12 algebra from the relativity principle. The latter goes back to Galileo in 1630. ;-)
    2
  983.  @tTtt-ho3tq  Science historically you are correct. We discovered Maxwell first, then we noticed that it was Lorentz and not Galileo invariant. That caused a lot of confusion and eventually Einstein sorted it out by showing that one could build a Lorentz invariant version of classical mechanics. It was only discovered in hindsight that all of this had basically been sitting on a few pages of algebra right in front of out eyes all along. I did, of course, not claim that a high schooler can solve this puzzle with nothing more than the algebraic tools that we teach in K-12. It took hundreds of physicists between Galileo and Einstein to put the pieces together, both experimentally as well as logically. All I am saying is that today, in hindsight, a smart student can understand all of this with nothing more than K-12 algebra and a bit of calculus and the concepts we teach about space, time and with the usual definitions for physical quantities like distance, duration, velocity etc.. Will this ever be easy to "grok" for a human being who is used to a world that looks Galilean? Probably not, at least not to ordinary humans who have been trained in our current public school system that is still very much based on 19th century thought patterns. The world is a little more complicated at the core than it appears on the surface. That's just a fact. We need to start teaching children this lesson earlier than we do today and then they will have an easier time to adjust to the actual scientific realities.

  984.  @titusfx  You are correct. It is not different. The problem with these examples is that some semi-smart physicist inserts a complicated Rube-Goldberg device into a simple problem. The analysis is just as trivial as you said. Whether a bomb explodes or not is a CLASSICAL event. No amount of QM intermediary mechanism can make this into a linear superposition of an |exploded> + |non-exploded> bomb. Such a thing does not exist. The device can also not guarantee that the bomb never explodes in the test because it is not interaction-free. What can guarantee that the bomb never explodes is a bit of black tape over its photosensor. That's 100% safe and effective. It's also 100% classical. :-)

  1026. The standard model is pretty constrained by math. There is not much about it that doesn't follow logically from special relativity and quantum mechanics as far as I know. And it's not like we didn't try tons of the possible variations. Pretty much everything that we keep discovering fits right in. What it is not, of course, is a TEO. It is entirely descriptive, with no deeper principle behind it other than a choice of symmetry groups. If anything, I would go the other way and say that there is nothing special about the three forces that we know about other than that they are close to a stability point. There can be a large hierarchy of other fields (or vacuum excitations, if you like that better), which are spurious and just not all that easy to detect because they are far away from the stable energy range and are therefor strongly suppressed in the 1TeV range. One can equally assume that our stability point is not actually the lowest one and that there may be an infinity number of (potentially self-similar) repetition at much lower energies. That would solve a lot of of the cosmological riddle, too. It would, of course, remove the last bastion of anthropocentrism by eliminating the human scale as something special.
    2
  1027. That's a very cute description of the introductory computer science class that I was teaching as a TA at my university.

  1028. Psychology is not natural science to begin with.

  1035. That free will as defined by philosophers is rubbish follows trivially from the definition. It's simply not consistent with reality. Free will requires that if you are being given the same choice multiple times then you can change it up. That's simply not possible because we can't replicate you and the environment perfectly, so neither "you" nor "the choice" are exactly the same every time we try to repeat such an experiment. Let's say I offer you the choice between chocolate and vanilla ice cream. The first time you don't know how either will taste, so you try either one of them. The second time you will be curious about the other, so your choice is already not free. Then you will develop a preference for one of the flavors and in the future you will be more likely to chose the one you like better over the other. Your choices are therefor never free. In the first iteration they are random, at best, since you lack criteria. In the second one it's more or less determined that you should switch and in all following ones it becomes memory dependent.

Of course you can't see progress if you are looking in the wrong place.

  1068. It is usually called a constant, but it is really an arbitrary function of cosmological time that one can put into Einstein's equations without destroying their meaning and that modifies the solutions of those equations. When we fit the parameters of the equations to what we observe, the fit is better if we use a finite value for this additional term. We can make the fit even better if we use a custom function. That, of course, is just a continuation of epicycles. It doesn't teach us anything. Mathematically these kinds of terms usually point to a physical mechanism in the microscopic derivation of the equations, so we know that there is, most likely, some real physics going on. We simply don't know what that physics is. Sabine Hossenfelder points out that one should not try to fill that gap with speculative thermodynamic models that do not behave, at all, like the universe at large.

  1076.  @Thomas-gk42  Energy, by definition, is a scalar quantity. It just doesn't transform like a "Lorentz scalar" because it is actually one component of a four-vector and the components don't transform properly. You could say "energy-momentum is a four-vector". That would be the correct way of talking about all of this.

  1084. The problem does not occur in Earth's reference frame. It occurs in SOME reference frame moving relative to Earth. As long as all causality is restricted to speed <c, all observers will agree that event A happened before event B if A happens before B in the reference frame of A and B. If the causality is connecting these events at >c, however, there is a reference frame in which B will come before A, i.e. in case of the grandfather paradox some observer will see you being born before your grandfather. I didn't think this through entirely, but intuitively one might expect time to flow in the opposite direction on the FTL ship itself (apart from the fact that it acquires an imaginary component which makes the system unstable). I Might be wrong about the last part, but the general lore about tachyonic systems is that they are always unstable. Now, all of this only holds if nature is actually relative. If it is not, then one can construct systems which have different energy bands, just like phonons and charge carriers in semiconductors. We would be in one of these bands and tachyons in another. There would be a gap between the two. By supplying enough energy one can "jump" the gap and then the new state would be in the higher band. We have accelerated protons to roughly 7TeV so far without observing this energy gap and "jump". We have been able to observe much, much higher energy cosmic rays (I believe by a factor of a million) and they still didn't become tachyonic, so if such a band exists, then it's at energies above the highest energy cosmic ray that has been observed. It would be completely useless for either communication or travel.

  1093. Nothing stops developers from shipping a game as a bootable bare metal software... except for sanity. The operating system abstracts all hardware differences away... so either a bare metal solution requires one specific set of hardware components OR it has to ship with all possible drivers (or load them from the internet, which is very similar to an operating system install). Good luck with the latter strategy. On dedicated hardware, however, bare metal is often a win.

So not only won't LHC data tell us anything about string theory, it won't tell us anything about ANY model of quantum gravity, unless that model is really, really wrong. But if LHC data or ANY data that we can generate today can't tell us anything about any model of quantum gravity, then why should string theory be given up, especially since it keeps teaching us new mathematical tools that can be applied elsewhere as well? Please explain in great length and detail how you get to such strange opinions. Having said that, I am not going to hold my breath.

  1113. There are neither particles nor waves here. There are only quanta of energy. Quanta give rise to a number of phenomena. A large number of quanta of the FREE theory (free as in free of self interaction) can give rise to mean field theories that look a lot like classical waves. Individual charged quanta can undergo annihilation processes but those are NOT part of the free theory. In an annihilation process we have at least two quantum fields (the charged fermionic field and an uncharged bosonic field) that are interacting with each other. Totally different physics.

  1121.  @NyscanRohid  Yes, there is a problem with people like Sabine who don't read the literature and who don't care about telling you the facts about quantum mechanics. There is no problem with quantum mechanics itself. You can find papers that derive its basic structure mostly from Kolmogorov's axioms in a few pages of mostly high school level algebra. So why won't you find that on social media? Because the reality of it is about as interesting as watching paint dry. Nobody would click on these videos if these social media influencers would tell you the truth.

  1122.  @berserk9085  Compare with the stretch from the early 19th century when spectral lines were discovered and the early 20th century when we finally found a quantitative explanation for them in quantum mechanics. This is nothing new and keeps repeating. We have seen this before... there were something like 80 years between Kepler and Newton, for instance and quite a bit longer between Copernicus and Newton. Atomism took 2000 years to make a breakthrough... so what's another 100 or 150 years? Most people simply don't understand quantum mechanics. People fear what they don't understand. It's irrational caveman psychology.

  1125. Hard determinism was a feature of Newtonian physics, or at least 18th and 19th century physicists and philosophers thought so. You are absolutely correct, chaos and more generally, non-integrability destroys that idea very quickly even in the Newtonian case. There are only a dozen systems in classical mechanics that are long-term predictable. Every other (of an infinite number of) such system(s) is not predictable. As soon as we are getting into relativistic physics it gets worse, because now the local future depends on the state of the universe that currently resided in spacelike separated regions of spacetime. The state of those regions is fundamentally unknowable until a signal from there reaches us as the speed of light. What this boils down to is that the future is generally NOT predictable. Any notion of determinism is therefor limited to special cases in which we already know the state of the volume of influence on our local future and even that is severely limited to highly symmetric systems (weather is not one of those systems). The problem is therefor more complex than the usual false dichotomy of determinism/indeterminism. The philosophical discussion has, unfortunately, not even caught up with the state of physics at the turn of the 20th century.

  1155.  @post_metro  And that is, indeed, the billion dollar question. "Time" only exists if there is an energy flow mechanism that allows us to "keep time" and to synchronize clocks. In other words, "time" is only a good order parameter in a relativistic universe in which there is no "absolute" matter background that blocks the flow of energy. Thankfully at the surface of last scattering the universe would have been transparent for both neutrinos and gravitational waves, already, so the universe could actually "keep time". Now, if we go back a little further the universe becomes opaque for neutrinos, but it's still transparent for gravitational waves. But what happens if we go back even further than that? Is there ever a state for which even gravitational waves can't travel freely? If there is, then the conventional definition of time breaks down and then, I believe, we need a new mental model for what spacetime means.

  1170. It's the same assumption as in ordinary probability theory, i.e. that all the experiments in our statistical ensemble stay in the ensemble, i.e. if we roll the dice a thousand times, then we divide the frequencies for the different outcomes by a thousand. Technically quantum mechanics and probability theory derive from the exact same mathematical axioms that are usually named after Kolmogorov. The central axiom is that P(x) + P(x̄) = 1, i.e. the probabilities of a set of events x and the complementary set x̄ add up to one. In probability theory we satisfy this with an algebraic equation p + (1-p) =1. In quantum mechanics we use the geometric relationship sin^2(phi) + cos^2(phi) = 1. With a little bit of algebraic manipulation this turns into a scalar product between vectors and from there we are in no time at the quantum mechanical Hilbert Space. This is not a big secret, we just don't teach it in most undergrad physics courses on quantum mechanics.

  1171. I agree but I didn't sense any animus by him against the political party itself. Instead he emphasized that the pacifist position of the German government is a necessity for a peaceful Europe, which is basically the core position of the German left. I think it is pretty obvious that absolutely nobody in Europe disagrees with the Germans on that point, either. A strong Germany is a serious threat. OTOH, Germany and Japan are both being dragged back into reality by their irresponsibly acting neighbors. They can not afford to be fundamentally pacifist any longer. They have to start carrying a big stick, potentially even a nuclear tipped one.

  1200. What is weird is that an endless number of authors have been trying to find "paths" for a quantity that doesn't have one. Photons are small amounts of energy. They are system properties. System properties never had any location or any path. They belong either to one system or the other. Quantum mechanics doesn't change anything about that.

  1201.  @skhi7658  Yeah, I actually got interested in the cosmological equivalent of the "mapmaker's problem". Unfortunately a search through dozens of math textbooks on differential geometry eventually turned up a bunch of theorems that showed that one needs at least six dimensions to have a "correct" embedding of a flat metric and ten for more complex cases. At that point I kind of gave up on ever understanding the true geometry of reality... my eyes don't work so well in six and ten dimensions... There are more misleading analogies like that. The "virtual particle" explanation for quantum mechanical uncertainty is completely wrong and all the "vacuum fluctuation" language that laymen are being sold is just plain nonsensical. If the vacuum was "fluctuating", then it would be glowing brightly and one could not possible see all the way to the beginning of the big bang. I have no idea why otherwise highly capable theorists keep pushing these false analogies that would fail undergrad students in oral exams.

That's your problem. :-) A worker owned cooperative is simply not socialism. It's a form of capitalism where the workers are the shareholders and active manages of the company. You can set up any LLC that way, your only limitation is with LLCs taxed as S corps, where you can't have more than 100 shareholders, I believe. You will, of course, run into the usual problems with early vs. late investors and the question how you re-distribute growth. Whatever you do, somebody will be screwed and there will be a lot of bad blood in the company because of that. Professional shareholders who do investments as a business can deal with that problem a bit more rationally than inexperienced individuals, but I, personally would not want to work in a cooperative for that reason, alone.

There is no universal algorithm that can solve an arbitrary optimization problem faster than full search. The entire premise of cryptography is the assumption that a good cryptographic algorithm can not be broken faster than by random guessing.

The role of the publishing house is NOT that of a go-between between the author and the printer. The publishing house has resources for research that the individual author does not have. Editing is not a mindless exercise in grammar. It's done to check factual correctness and/or improve literary quality of the work.

  1246. No, not really. It was Moore's law that put an end to custom machines. I was working on a high energy physics project in the early 1990s that used field programmable gate arrays for performance reasons (we had GByte/s data coming in at packet rates of 60MHz). By the time we were done it would have been easier and cheaper to implement the entire crate of electronics on standard CPU boards. It also would have made it a lot easier to program. Today I could write the entire algorithm stack in C or C++ in a couple weeks and run it at 10x required speed on the GPU of my laptop. Back then it took a dozen physicists and EEs to build the hardware and write the VHDL code.

  1249.  @Andreas-yt9wv  It doesn't matter what Penrose believes about Schroedinger's cat. You can read Schroedinger's own works and they demonstrate that he was utterly confused about the meaning behind quantum mechanics. This is a common phenomenon among "the founders". Einstein made a huge mistake in his 1905 paper on the photoelectric effect. Heisenberg has moments of enormous clarity but then he backtracked and kept preaching the wrong solutions for the rest of his life. To some extent the history of quantum mechanics is a comedy of errors. We can laugh about it, in hindsight. Back then they were just utterly confused. They still got it right, though, which is amazing. You just have to learn to pick out the pieces they got right and learn to ignore the nonsense like Schroedinger's cat.

  1280. The problem with the "there is no multiverse" terminology is that it makes a statement about unmeasurable things. We know that special relativity and general relativity restrict large volumes of the universe to "unobservable" status. We can, for instance, not know what is happening on Mars, right this moment. It takes roughly 3-22 minutes for a signal from Mars to us and vice versa. Reality on Mars during those delays is "off-limits" to us. Does that mean that nothing is happening on Mars? Of course not. It simply means we have to accept these limitations in knowledge. The universe "outside" of the observable universe falls into the same category. It could be doing a lot of things and we can't know. We can model, we can extrapolate, but we can't know. Not this way and not that. The real function of the responsible educator is to teach people to cope with these kinds of limitations in a rational manner. With regards to religion... to compare multiverse models (which are based on speculative but precise reasoning) to religion gives too much credit to religion. There is nothing in religion that comes even close to the level of detail and care that theoretical physicists are using.

  1284. It probably depends on how you count. If you take a tightly packed rooftop array that has no additional land requirements, then it does. If we compare a typical reactor site with a typical large scale solar farm, but without externalized cost for the reactor (like impact on cooling water resources etc.), then nuclear probably has a leg up. It doesn't matter, though, because solar electricity is cheaper by the kWh.

  1285. It's not defeatism but rational analysis. You can go at it from an entirely different angle and using the tools of an entirely different profession. Ask a real estate agent what they think about buying lots on Greenland, the Moon and Mars? What do you think will they say about value? Location! Location! Location! There is simply no market for Greenland real estate and that is, at least, accessible without risking your life for it. So why would there be a market for lunar and Martian plots?

  1303. They are not determined only locally. There is a component that comes with the free field, but then there is another component that comes from the measurement system. The real problem here is that the free field and the field that makes the measurement system are actually the same field. It's only the physicist's divide-and-conquer mindset that tries to distinguish between the two. In quantum field theory we are completely giving up on that concept and we are merely distinguishing between interacting fields (at short distance) and non-interacting ones (at long distance). That's a much more natural way of looking at nature than the two systems approach.
    2
  1304. I know. One can say a lot of things about quantum mechanics but not that it is not confusing the heck out of a lot of people. To me the most surprising thing about it is that we managed to figure it out at all. The problem is compounded by the fact that "local" in a relativistic world carries a very different set of consequences than in a Newtonian (Galilean) world. Relativity is the real reason why there can be no local variables to begin with, but that is rarely discussed at the level of introductions to QM. That is a shame because many of the perceived problems with QM are going away once we start looking at it through the relativistic lens. We are trading those ontological solutions in for a very large number of highly complicated mathematical detail problems in quantum field theory, which explains why almost nobody dares to touch on the intersection of relativity and quantum mechanics at this level.
    2
  1305. I have managed to sort it out nicely in my own mind over the years, mostly by trying to explain it to other people over and over, again. The first few hundred times I was talking complete nonsense, of course, just like everybody else. Eventually it clicked and now I have a number of actually workable analogies and examples, but yeah, it took a decade or two to get there. Feynman really didn't do the the world a service with that statement, if it is by him, that is. Of course he was joking, but most people seem to take it at face value, which is a pity because then it becomes an anti-intellectual statement that defends intellectual laziness. I learned that quantum mechanics can not be treated with logic when I saw that the operator algebras in quantum mechanics are non-commutative while Boolean logic is a commutative algebra. So that's really a hard mathematical fact. We should be teaching these non-commutative structures much sooner, preferably at the middle school level when we teach children "ordinary" algebra. I think it would make student's minds much more open to "unusual" and "unintuitive" ideas if we would show them examples of "what else is out there" early and often.

  1308. Well, there is not much difference between those two desolate places...
    2
  1309. Because the definition of force does not include gravity. Newton called ONE effect that causes relative motion right, he didn't call ALL such effects correctly. The problem for most people is that we don't teach it like that in school. Instead we are pretending that Newtonian gravity is the correct solution and that everything is fine. They already knew better at the time of Newton, we just didn't have the observational data to go beyond what we knew could not have been entirely correct. Now we do and it would be better to teach forces as one thing and Newtonian gravity as a completely different one right from the beginning.

  1310. No offense, but this is not how people were living 300 years ago. Amish homes have modern materials like glass, stainless steel and plastics everywhere. People are wearing shoes made in China and they have modern glasses. Not even the kings of that time had such luxury items. They were simply not available. Many Amish farmers use GMO seeds and they do make use of modern medicine, even the vaccination rate is not that much lower than that of the general population. It is therefor not true that the Amish are living "in the past". They have a "selective" lifestyle but they are reasonably practical people. Whatever we may think about these choices, a modern Amish community could not exist in the current form without being embedded in the remainder of the world economy. And there is nothing wrong with that.

  1314. You can find dozens of quantum mechanics textbooks for free on the internet. If you want to know where all of this is going once you get really into it, that can be explained with a single sentence: "Quantum mechanics is the theory of the unitary representations of the Poincare group.". Unless his book would take you there on page one, it wouldn't be any better than the rest.

  1317. Einstein was one of the physicists who pointed out its existence. What he failed to understand (or so we think) is that it was caused by relativity. It is, of course, possible that he did understand it, but if he did, then I just don't know where and how he communicated that to his peers. I didn't read all of Einstein's writings, though, so I might be missing something.
    2
  1318. Yes he will. They just like to play political theatre to the last minute.

  1319. Wait... why did you guys not put in the long hours in high school and college or university to become engineers? Did you really think that you would get a cushy life on the assembly line at 50 dollars an hour? Unbelievable.

  1320.  @tylerhunt7552  What you want and what your labor is worth are two pairs of shoes. Manual labor had a lot of value before automation. Now it has almost none. Now the work of the automation engineer has more value. Why don't you cry some more? Maybe that will help? :-)

  1321. @ There is no multiverse. There is simply a misunderstanding about the structure of the theory. In the lab we measure individual quanta of energy. When and where these quanta of energy show up in our detectors is not predictable. What is predictable are their average frequencies when we repeat the same experiment often enough. And that is the only thing the theory predicts: average outcome frequencies under multiple repetitions. The universe is not a repeatable experiment, but people who want to assign a wave function to it treat it like as if it were repeatable. That NAIVE extrapolation is what creates the multiple universes in MWI. It's simply shoddy thinking that can't distinguish reality from theory.

  1322. Interference is not an effect. It's a consequence of the absence of an effect. It only occurs in linear systems that have no self-interaction. We try to teach this in high school using a wave pool or a wave machine. Unfortunately it's a rather subtle learning unit and most students do not understand what it is that we are trying to teach them. Why is quantum mechanics linear? Because individual quantum events are statistically independent. It's baked into Kolmogorov's axioms and it follows from the observation of conditional probabilities, but you would have to develop a solid intuition for probability theory, first, to understand why quantum mechanics follows the same rules and how that leads to linearity of the formalism.

  1324.  @macschomo  No, but it's not caused by quantum fluctuations, either, we just don't have a good language to talk about these things. We can see the problem already in the ground state energy, which ought to be enormous, according to the usual calculation methodology. Instead the effective ground state energy is tiny. So that tells us that something at the interface of quantum mechanics of fields and the underlying geometry of spacetime is broken. It's probably the same technicality that makes it so hard to deal with gravity in a quantum mechanical way. So where does this problem come from? For one thing, it comes from our definition of "physical event", which is classical and point-like. That, already, would cause an infinite energy term in the most naive formulation, right? We can not even implement a single "point" in spacetime with a proper physical system without running into the infinity problem, but our theory then happily goes on to integrate over an infinite number of four dimensional spacetime integrals to get to a finite result (with some very heavy lifting in the symmetries department that offset some infinities against others). Moreover, the ground state energy was infinite in classical mechanics, already, if you remember... if we integrate the energy density of a point charge all the way to r=0, then we end up with a divergent integral, so the problem is not even quantum mechanical, it is a general conceptual difficulty with the infinitely "small". Nature does not have that problem. It simply does not "start" with spacetime, at all. It does not seem to care about the "infinitely small". It only cares about whatever scale is of relevance based on the total energy in the system. Instead, spacetime "is" what "stays behind" in an abstract way (that can, as I said, not implemented with physical systems) once we strip all matter and radiation out of the actual physical solutions. Now, if I could tell you how to implement this with a mathematical model, then I would be in line for the physics Nobel. As far as I know nobody can do this, yet, but we can still point to where the problem originates: from dragging the classical mechanics picture too far into quantum mechanics.

  1329. Westinghouse and GE NEVER funded astronomy or high energy physics. If you take the government funding out of academia (which no sane nation will do, and we can argue whether the US is still one of those), then you would simply lose all of your PhDs and MDs. The US makes way too few PhDs and MDs, by the way. Both of my cardiologists are from India and when I worked in DOE government labs myself we had roughly 40% foreign PhDs. Today it's more likely closer to 50% in those places.

  1334. The King David Hotel is an interesting example of selective historical amnesia. The perpetrators gave ample warning that an explosion would occur, yet the hotel was not evacuated by the authorities in charge. Anybody who doesn't mention that has an obvious agenda that does not shy away from falsifying history. As far as Israel's actions now are concerned... they make perfect sense. The Israeli state has a responsibility to keep its citizens safe, even at the expense of the lives of those who threaten them. That is the standard definition of the powers of the sovereign state. It can respond with absolute and even unreasonable violence (that's the standard definition of war, if you like) to protect itself and those who form it. We may wish to live in a world where such arrangements are unnecessary, but recent events (not just in Gaza) have proven beyond any doubt that we don't.

  1338. That still requires artillery shells. What the West has said with the F-16 training for Ukrainian pilots is this: we will support Ukraine for at least one more year at ever increasing weapons system efficiency. To Russian soldiers this means another cold winter in trenches without food and ammunition and under constant threat of drone and precision artillery strikes. Russia's military has nothing to contest either. By next summer its air defense systems will be so depleted that the F-16s will rule the sky and the ground. At the current level of hostilities Crimea will be cut off by then. If Russia decides to make a last stand there, its entire army in Crimea will be destroyed and captured. Senior officers know what that will mean to them, so all the fighting in Crimea will be left to junior officers and common soldier. ;-)

  1339. That is exactly what Sabine is doing, though. She simply lies about it with a fake authoritative tone of voice. There is no there there once you dig through her crap.

  1340.  @ashedtogether  Nobody gives a shit about her personal experience. The world does not evolve around Sabine. She needs to grow up. Of course academia is brutal in the sense that somebody is always better than you. It is also paid for by TAXPAYER money, which means that a scientist is RESPONSIBLE for using it wisely. That takes a lot of hard work. Let me spell this out for you in bold, even though I hate screaming on the internet: THIS IS NOT A GAME. We don't get to do this exclusively for personal enjoyment. This is serious business and if you want the money, then you have to deliver.
    2
  1341.  @ashedtogether  Yes, that's a lie. I have been involved in the grant money process and there was nothing junk about it. It was the hard work of dozens, hundreds and in one case thousands of professors, lab scientists and PhD students. If you think it is easy to get some money from a funding agency with some bullshit, then you are not thinking. That, exactly, was Sabine's problem. She wasn't getting enough grants because she was pushing bullshit. You can see it in her own publications. She just doesn't have it.

  1345. Is that what Russian state tv keeps saying? ;-)

  1358.  @FreeKekistann  One could imagine panels that are actually cooling the land by reflecting most of the IR radiation and by having an emission peak for IR wavelength that correspond to the Planck peak at 300K. That would reduce heat load by 30% or so. It does come with some efficiency loss and the production is more expensive, of course. Other possible combinations involve solar and thermal desalination.

  1366. That's correct. There is still strong migratory pressure as people from the countryside are moving into mega-cities. IMHO the rich will mostly move out of the cities and the poor will move in.

Like Forth it's a bit of a brain-frell syntactically, but tastes differ and if you only had a choice between assembly language and Lisp, Lisp might still be the better choice for most applications. Of course, if you are given the choice between Python and Lisp, then Lisp goes out the window fast (at least for people who have more than 30% sanity left).

  1389.  @JohnSkeel  No harm no foul. I used to call it a bronze age religion myself... until I looked up the timeline for metal cultures. To my surprise the first confirmed dates of OT texts barely fell into the last century of the iron age... which tells us that people were far better with metal working than with their belief systems. I think we should give them that much credit. The smart ones were smarter earlier than the dumb ones were really dumb. ;-)

That's the modern form that is in use by most theorists today if I am not mistake (I am not a theorists, just talking to some on occasion). In general most of the "interesting" things in theoretical physics are happening at the level of group representations, Lie-algebras and now even topology. There has been quite a bit of shift in physics from more or less "point and shoot" calculations to mathematically well founded formal structures.

Moreover, China's population is declining, which means that all of its GDP growth has to come from an increase in GDP per capita, which will make China less and less competitive in the global markets. China's goose is cooked. Or, better, it's Peking Duck is broiled. :-)

  1399. Photons don't travel at all. That's just a failed mental model that shows its weakness in situations like this where it makes no sense whatsoever. What you are noticing here is not a problem with the quantum mechanical description of light in solids but a problem with the semi-classical notion of photons as tiny moving particles of light. One can, unfortunately, not even use the simple quantum mechanical picture of a photon as an irreversible energy transfer. That only works for emission and absorption phenomena and optical refraction is neither. At the quantum level refraction is a very complex multi-quantum phenomenon that requires us to analyze the solid as a series of coupled harmonic oscillators. It can be done and it has been done, but it's usually a bridge too far, both for laymen and undergrad physics students. I have a book about the topic somewhere. I gave up reading it after the first dozen pages (I am a high energy physicist by training), the theoretical details are that boring and tedious.

You don't sound like the kind that works hard. ;-)

  1404. I looked at her publication record and it is pretty lame for the most part, at least recently. She publishes fluff pieces about the foundations of quantum mechanics, which really nobody cares about and "yet another dark matter model" kind of stuff. In other words... she does exactly what she accuses other theoretical physicists of doing. I don't blame her for that... she doesn't have the data, either. She is basically spinning her wheels until a group of experimentalists will find the next big clue.

  1406. The only problem with string theory, as with many other quantum gravity models, is that it doesn't connect to reality in an accessible energy range. That is much more likely a problem with gravity in general than with string theory in particular.
    2
  1407. Neither do the guys who came up with this hypothetical experiment that doesn't work like that in reality. :-) In all honesty, It's just a Rube Goldberg version of the double slit with one slit covered up and slightly improved detection odds.

  1410. Mathematics is not a model. It's an abstract extrapolation. We find five stones on the beach and we learn to count them. Then we count a bag full of rice and it's boring like heck. We say "F it!" and postulate that no matter how big the sack would be, we could always assign a number to its contents. THAT is how math is born. At some point you just give up looking at the real world and you say to yourself that you have enough evidence to just go with a simple rule. The intuitionist, however, goes one step further and says that "We don't know unless we do.". The little problem with that is that every time we do, we find that the intuitionist was just a drunken guy who was full of it and we could have saved us a lot of work because nature ALWAYS gives the result that ordinary logic predicts. In other words, that drunken a-hole made us run around for nothing. ;-)
    2
  1411. You are kind of close there. A "hard" search problem has exactly one global optimum (or, at most, a finite number of equivalent optima) but an exponentially increasing search space. So basically guessing the solution is unlikely to deliver a result for large problems. One can show that the hardest of these problems are equally hard for classical computers and for quantum computers. They are generally unsolvable even with the resources of the entire universe for suitably large problem size. If, however, we reduce the requirement from "perfect solution at any size" to "good enough for some size", then classical algorithms and quantum algorithms have different performance. It's that difference that QC might be able to exploit.

  1412. One of you favorite science communicators told you a lot of nonsense about physics. The only reason why you can't tell is because you don't know physics to begin with. :-)

  1427. What we "have learned" is brand new. We are generating tons of new data at LHC and other facilities, neutrino and dark matter experiment etc. that was not available in the past. It just happens that we had the basics already figured out in the late 1920s to the 1960s. That's what happens when your theoretical physicists know how to do their jobs... they are ahead of the experiments by decades. It's a sign of success, not failure. ;-)
    2
  1428. A measurement is an irreversible energy exchange. It does not have to be a macroscopic body that captures this energy. Even the loss of energy towards infinity (e.g. escaping electromagnetic radiation) is "a measurement". Technically that's the only measurement we need in quantum field theory (outgoing plane waves) but since we are impatient we usually put a thick piece of matter in the way of that outgoing radiation and we give it a fancy name like "detector". :-)

  1429.  @Roescoe  Functional programming is impractical. That's not a matter of when and if. It sounds good on paper using trivial examples with functions of primitive types. In reality, however, the concept falls apart as soon as complex data is in play. That's the difference between academia and reality. That doesn't mean you should never use functional concepts like filters and maps, it simply means that not everything can be practically reduced to the paradigm.

  1433.  @Langkowski  Photons don't have paths. That's one of the grand misunderstandings of quantum mechanics. Quanta are small amounts of energy. Energy doesn't have a location and it doesn't have a path. It's not a classical object with center of mass coordinates. Even in classical mechanics energy is a system property. It "flows" from one system to another, which reflects local energy conservation as an accounting principle, but it was never meant to pretend that energy can be localized below the system level.

  1434. Yes, I have been on Chinese transportation systems, too. The trains are an awful waste of time compared to flying and buses are so full that one can't go anywhere during rush hour. China has not been able to solve its transportation problems. An increase in personal car use will do only one thing: clog China's inner cities completely.

I don't give up easily on people, but when I do it's very hard to reverse that decision for me. I need to see some serious proof of sincere remorse. Let me know when the Palestinian people can show that emotion. I am certainly not impressed by their PR. I wasn't in '72 and it hasn't gotten any better.

  1441. A neutron is a long lived baryon (i.e. a state of three bound quarks). Why is it that? Because nature makes quark states with two or more quarks. The only stable bound quark state is the proton (or, at least, it has extremely long lifetime). The free neutron state lives for approx. 900 seconds before it decays into a proton and an electron plus an anti-electron neutrino. In nuclei neutrons can be stabilized for very long time.

  1457. Yes, you are thinking about it in the right way. OOP was originally invented to allow automatic code reuse by the compiler on machines with very small memory (typically 16kWords). The chosen granularity at the function level does, however, lead to the opposite. If a child class wants to change just one line of a hundred in the parent's member function, it has to either fork the entire function (welcome to code duplication debugging hell!) or it has to decompose the original member function at the level of the parent into three parts (beginning, middle, end) to change the line in middle(). Sounds like a fun game a rational programmer will play, doesn't it? Just kidding. ;-)

I learned some of my core physics intuition from mathematicians. Having said that, you can see the actual difference in the experimental physics lab section. All those gadgets cost a lot of money. The most a mathematician will ever need beyond an office, pen, paper, a whiteboard, a laptop and the library is supercomputer time. Physicists need equipment worth tens of billions of dollars. That creates a very different level of accountability to the taxpayer.

  1480. First of all, there are no particles. What we are detecting in quantum mechanics are quanta of energy. Quantum mechanics only concerns itself with energy conserving system, hence the total probability of detecting the energy in a quantum experiment is always 1. The distribution of that energy depends on the details of the system. In systems that show tunneling energy can even be detected in regions for which the equivalent classical experiment would not have a non-zero energy density.

  1487. Scholars don't believe that these texts are "inspired". They know that they were written for a purpose which was often political. Try to read the Torah as a political manifest similar to the The Palestinian National Charter and you will immediately understand much more of what is really going on in the Abrahamic religions: a struggle for independence by Jews and, seven centuries later, a desperate wish for release from their earthly misery by Roman slaves. So, no, the books don't talk as much about legends or myths or magical tales as they talk about the real suffering of millions of people over almost an entire millennium. Can you find god in there? No, of course not. You will find plenty of misery, hate and PTSD, instead.

  1491.  @ChuckCreagerJr  I agree. Some people do awful things to other people. Being dumped or even cheated on is, however, one of the less awful ones. Domestic violence and other forms of abuse, sometimes for economic gain, are far, far worse. One of my best human experiences was a dinner at the house of a female co-worker. Also present were her teenage daughter, her current boyfriend and her daughter's father and former husband. The four were having the most pleasant intellectual conversations and they genuinely seemed to get along with each other just fine. I was informed that this dinner was a weekly ritual. I asked her about her divorce later and she told me that she and her former husband had both come to the conclusion that they had made a mistake when they got married, that they both loved their daughter equally and that they did not want to let their failure to be a couple come between either of them and the child. The result of that thinking process was a terrific arrangement as far as I can tell. At the opposite end of a spectrum I once made the mistake of wanting to drop off a donation at a women's shelter. I walked up to the front door and rang the doorbell. The result was frantic shuffling behind the door and a threat to call the police immediately if I didn't leave. The situation was only rectified by one of the employees who knew me personally. Why was I being greeted with such a response? Because the shelter had been receiving violent threats from the husband of one of the sheltered women. They were genuinely afraid that the guy might show up to commit an act of violence. So, yes, human relations can be traumatic, but they don't have to be. It's all about what we make of them.

  1492. If you think that string theory is physics, then it only shows that you don't know anything about physics. Physics is what they do at CERN and other laboratories. Did you ever take the time to visit one of those? I can guarantee that you won't see any strings there when you do.

  1493. Time has a direction because time is that which clocks measure. A clock is simply a system with a local energy source that slowly and steadily releases that energy towards infinity. Why does a clock only run one way? Because there is more volume out at "infinity" than there is near the clock and energy has a tendency to spread out. So what "time" is, is just the precise measurement of the tendency of energy to take in as much space as possible. Now, why does energy spread out? Well, it doesn't always spread out. In a system in thermodynamic equilibrium energy doesn't spread out and such a system is static. It doesn't even make sense to define time for such a system. So what is missing from this puzzle? A microscopic understanding of "volume". We don't know what causes spacetime to be geometric on our scale and we don't know if it stays geometric on all scales. The microscopic explanation for both time and energy are therefor at the scale where geometry emerges from "something else". It is this "something else" that we are really missing.

  1498. You can learn to "code properly" in any language, even Malbolge. If your employer wants you to use Rust, then learn to use it. Do I see a need to learn it if no such requirement exists? No. The problems I have in my daily life can be solved perfectly fine with a combination of Python and C (not even C++). So what do I need another language for?
    2
  1499. One does not have to lower the pressure in a tunnel for a car. The aerodynamic resistance is the least of the problems there. The problem is the absence of a track. Cars colliding with walls at high speed are not such a good idea. Electronic track guidance works, until it doesn't. There has to be a passive failsafe to prevent the worst kinds of accidents in high speed tunnels. I think that is probably some that Tesla and Boring still have to work out... a vehicle platform that has enough safety margin to allow high speed underground transportation. Having said this, high speed is not necessary for tunnels to be useful. The core problem for cities is that major roads are blocked during peak hours and the transportation capacity collapses. What we really need are low speed bypasses that retain the ability of a city to function even during peak hours. Getting across Manhattan or L.A. at 35mph is a lot better than at 1.5mph in stop and go traffic.

  1502. Yes, that's not how quantum mechanics works. ;-)
    2
  1503. That is true for classical waves. The energy density is proportional to the square of the classical amplitude. In quantum mechanics these classical waves don't exist, so one can't take the squares of their amplitudes. We can, however, recover them for the case of electromagnetism by using a theory of positive definite energy transfers alone. These small amounts of energy are called "photons". This is a special case, though. Other quanta (like electrons) do NOT lead to a relatively simple classical mean field theory like electromagnetism.
    2
  1504. Do you know what the philosophy department calls "training on inference"? Philosophy. You can justify any nonsense with that because you can start from an arbitrary set of false assumptions. Now, you can ground all of that in facts, but for that you have to do science, which means that you have to let your AI go into the lab and do hands on research. Do you know anybody who does that? ;-)
    2
  1505. Yep, that's 100% false. :-)
    2
  1506. Yes, the key word there is "believe", which only idiots will use in conjunction with science and mathematics. String theory is quite well defined in its function, it just didn't lead to the kind of structural breakthrough in science that some people were hoping for. We had situations like this before, e.g. with Bohr's model of the atom. It was a step in the right direction, but it didn't quite get us there.

  1509. What is happening here is that the compiler moves some stuff that you would do without OOP at runtime (like type checking) into the compile time domain. That can occasionally save you a few bytes of executable and a few ten ns of execution time. Other than that you are buying a world of hurt, which you won't notice until you are working on a large OOP project. At the end of the day you have to understand that there is no such thing as an OOP executable. By the time the compiler is done, absolutely everything that you wrote in OOP style has disappeared. In other words... OOP is basically just a documentation style.
    2
  1510. One can update objects at any time with a call to an object method just like one can update the value in a loop variable with a simple assignment. Writing a loop and an assignment makes the code readable for absolutely everybody with even the slightest amount of knowledge about procedural programming languages. Using send() will make 99% of programmers scratch their heads (including the ones who know what it does) and ask what kind of idiot will use such a construct. Guess who they mean by "idiot". They mean you. And that, by the way, includes yourself. You will call yourself an idiot for using this construct the first time you have to read your own code six months later. Simple is beautiful. Keep it simple.

  1512.  @user-bf8jl1mj2k  I only had one job and it was related to my field, so I could actually learn on the job. That experience turned out to be quite helpful later. I never felt that having to work came between me and my studies. Of course I was younger and my stress tolerance was significantly higher, so there's that. The only time I was totally broke was at the end of my thesis. I even had a job lined up at the time... but I had to ask the employer for a plane ticket and stay with friends for a few weeks until I got my first paycheck. I never needed a loan since, so I can't complain about the value of my education.

  1513. Copenhagen doesn't make any assumptions about the observer. All it requires is irreversibility. There are trivial quantum processes that are irreversible without any classical observer system. This follows directly from special relativity which separates the world sharply in forward and backward light cones. The problem that you have in non_relativistic single particle quantum theory is that you have so over-simplified the world that you are losing the very effects that cause classical states to appear in the first place. This problem doesn't exist in relativistic quantum field theory and that's why "interpretations" are not required in high energy physics at all. Nature separates local reversible dynamics and global irreversibly dynamics for us automatically. All exact observables are simply living at infinity and any and all attempts to "zoom in" trivially results in a non-classical "smeared out" description of the world. People who have experience with a regular light microscope are familiar with that: no matter how good the objective lenses are, at higher magnification the "images" are always blurry. That's not an engineering limitation. That's nature showing us that reality is locally simply "not in focus".

  1516. That's exactly the delusion here. Middle class were always wealthy and comfortable. They were just not wealthy in the sense of an aristocratic landowner who had tens to hundreds of thousands of acres of land and a few (ten) villages under his control. Today's middle class have annual incomes of a million to tens of millions of dollars and they own one or several high quality properties free and clear. You would have to be extremely generous with the definition to extend it to someone who makes half a million a year, but that's probably as low as it goes for the "poor relatives" of the middle class.

  1520. The entire military industrial complex of the US is centrally planned. It is, most likely, by size the largest centrally planned economy in history. Works pretty well, for all I can tell. The US R&D system, which I was part of as an employee of the national labs, works extremely well. I have rarely seen organizations that were so efficient and well equipped to get the job done with lots of highly motivated and extremely intelligent people.

  1521. The problem with your argument is that string theory actually follows directly from Galileo's work. Even though this was known before him, Galileo was the first to give a modern description of relativity. It took almost 300 years to extract a mathematically precise physical theory from that description. That was Einstein's theory of special relativity. Einstein then upgraded that to a version that also includes classical relativity. In parallel we learned how to formulate all of matter and radiation with a relativistic theory that is called quantum field theory. If we try to include gravity into the quantum field theory framework, then we end up with string theory as one possible solution. So, yeah, string theory was implicitly already present in Galileo's work, he just didn't know how to tease it out.

Newton's third law does not apply to it, for instance, (at least not without some serious fudging) and physicists were always aware of that. The definition of "force" works very nicely for contact forces, but it has serious problems for fields and it completely breaks down for metric effects like gravity.

    2
  1537. That's a common misunderstanding, already. There is a classical object called a string (like a violin string) that has a certain elastic property in a narrow range of stress acting on it (beyond which it brakes). Its idealized physical description (without the possibility of breaking) is given by a physical action that has very interesting and desirable properties for certain physical applications. String theorists take that ideal action and use it as one of the entry points into the theory, but they are not literally talking about physical objects that have string shape.

  1562. I can certainly not find much in von Neumann's book that would support the idea that he didn't understand quantum mechanics. I used to think that it was the formal character of his writing that caused a lot of the confusion and the "shut up and calculate" attitude, but then I read chapter 6 and he has some really healthy intuition in there. Wigner, however, seems to have been as confused as Schroedinger about the fundamentals. I would have to check his science writing, though, to see if the hearsay about him is correct. That Schroedinger was confused is fairly obvious from his own publications.

  1563. I have a Macbook from 2011 that runs just fine on an old version of OS X and a PC from 2013 that runs WIndows 10 that can't be upgraded to 11. I do all my engineering design work on that machine. There are ZERO problems with using either computer. You are talking absolute nonsense. If you don't know how to make emergency repair discs and backups for old Windows computers that can be use to replace installations after a hard drive failure, then you are the last person on Earth who should be meddling with people's computers. If you have much older hardware than that, then it's more than likely that the decoupling caps around the CPU will fail soon, anyway, which results in a dead motherboard that you won't be able to repair, either.

  1570. You are correct. The difference between Western countries and Asia is that Western countries can grow through immigration. The Japanese, Koreans and to lesser extent also the Chinese are cultural isolationists. The US in particular, already has a Mexican manufacturing belt on its Southern border. In my opinion both the US and Mexico would greatly profit from making parts of that manufacturing belt a free trade zone. We could move the border fence into Mexico and create a safe zone for working class families from Mexico and Central and South American families who are trying to escape the criminal and political violence in their countries. It would solve the US immigration problem and stabilize Mexico and Central and South America.
    2
  1571.  @TheMightyAbs  The unfortunate side effect of it is that the US and other well developed countries have been depleting economically less developed countries of educated people. This has been happening for a long time, of course. One can see the devastating effects even in some smaller European countries that are struggling and that have been moving to the political right of the spectrum. What else can be expected if we are removing young, left leaning middle class voters? Poland, Hungary and the former Eastern part of Germany are good examples of the political consequences of this migration. Of course this doesn't spell impending doom for China, but it means that the country is changing very quickly. China did try to mitigate the consequences of their one-child policies, but there is only so much it can do. I went to visit some time ago and I saw plenty of young people from rural areas in the big cities. The problem is that most of these young people were working low end jobs in hotels and restaurants. They weren't building a future for themselves by moving up the socioeconomic ladder. China's last young generations are now depleting the villages without actually adding all that much to the country's GDP. At the upper end the country has created millions of young employees with four year higher education or better, many of whom are now unemployed, so the growth in technological, service and administrative positions has not even kept up with the successful part of China's educational efforts.

What is possible is for NATO to support Ukraine until Russia is out of viable military options and withdraws. After that single NATO states can give security guarantees to Ukraine and the process of full NATO integration can begin. Russia will, of course, try to keep the conflict alive indefinitely to prevent a formal membership. What does that buy Russia? And endless war that it can't win. ;-)

  1591. This video has a very skewed definition of "intelligence". On some level it sounds like it mistakes "skill" for "intelligence".

Having an even more specialized skill does not make a person even more intelligent.

We need to replace it with something else because it causes endless grief. I generally like to use the word "uncertainty" instead because that is what it is. Energy, momentum, angular momentum and charge are fully conserved, there is simply always another system out of our reach which is entangled with our local measurement. The important thing to understand is that this lack of knowledge is fundamental. It is NOT just a technical limitation of our equipment. It follows directly from special relativity.

  1601.  @ewallt  Quantum mechanics requires the existence of an ensemble, i.e. the ability to repeat the same experiment many times. The universe does not satisfy that requirement. It is popular to talk about e.g. the wave function of the universe (Wheeler in particular made a hobby of it), but it's complete intellectual nonsense. The universe is simply not an ensemble experiment.

  1602. How protected you are from covid is mostly a function of your immune system. Every person has a different immune repertoire. We can only draw on these individual repertoires in response to an immune system challenge, including a vaccination and a booster. Unfortunately this means that if your personal immune system is poorly matched to the virus, then no vaccine can protect you. If it is well matched and you have a strong response, then you don't even need a vaccine to only develop light disease. What average quantities like the antibody count tell us is how well the average of the population may be protected. That is very important for epidemiological purposes, but it is close to meaningless for you individually. To rely on these averages for your personal protection is therefor a dangerous scientific misunderstanding. You should always minimize exposure to the virus because that is the only reliable way of keeping yourself safe. To say this in a different way: vaccination campaigns are tools to keep the population as a whole safe (which includes you as it removes the source of infection), but they are not designed to assure your individual survival in an absolute way. This is the reason why it is much more important to vaccinate everybody than to vaccinate only individuals who are seeking personal protection.
    2
  1603. It's not the electrons that are causing this phenomenon, at least not directly. It's a collective excitation of the crystal lattice which gets polarized. The correct theoretical explanation is, unfortunately, much more complex on the quantum level than e.g. the conductivity of metals or semiconductors and if we really wanted to take this on correctly, then we would also see effects like Raman spectra and solid state laser theory drop out of the math. That's why we usually simplify this problem to the classical level, which for most optical and materials applications is perfectly sufficient. In terms of math this brings us from coupled quantum mechanical linear oscillators to classical polarization.

  1606.  @jonblaze4244  You don't have to believe all the bullshit you are hearing on the internet. Amazon is now profitable enough to pay corporate income tax. All of its employees are paying personal income tax and social security tax and medicare taxes, all of which come directly out of Amazon's revenue. Then there is the additional sales tax that Amazon generates by increasing personal consumption. Amazon has been building very expensive facilities and operates a large international fleet of delivery vehicles. All of these economic activities generate tax revenue at Amazon's suppliers. That rich folks don't pay taxes is bullshit. They may not pay income tax, but at the very least they are paying capital gains tax. If they have people working for them, then they are also funding personal income tax and social security tax payments, yet again.

What will happen, of course, is that the arid and semi-arid areas will be moving North very quickly. We will lose large parts of the European and North American forests. We will have to change our agricultural methods in addition to use less water, which will mean more production under foil and in greenhouses. Solar architecture offers perfectly viable solutions that can grow more produce on smaller land areas with less water while producing endless amounts of energy. It could be done today, if necessary.

  1613.  @YannickIgten  It would be better if none of this became necessary, of course. I am not saying that technology is a panacea. We will have to change our ways, but that's normal. It's a far smaller change than during the 19th century when we replaced human labor on fields with machines, anyway. And cities... well, some will innovate to provide shade and cooling and others will become unpleasant hellholes. Ask your city to start planting some really tall trees from the African Savanah... you children will be thankful.

A professor of mine used to say that you will be forgiven for being wrong by an order of magnitude. It's factors of 2 and pi that are unforgivable because then you got your calculation wrong for sure. We had lively discussions about how insecure Einstein must have felt when 8pi dropped out in general relativity. :-)

  1620.  @TieTo-s4g  I think there is a common misconception here. The goal is not to send Russia packing quickly. The goal is to destroy it completely and once and for all. This will also send a message to other players like North Korea and China that war doesn't pay. While this may extract a slightly heavier toll on Ukraine than would be necessary if Russia was defeated quickly, it will assure lasting peace. The measures taken by the US and other allies of Ukraine will ensure that Russia will never attack anybody else, again.

  1630. Thank you! You did me an enormous favor. I went back to the paper by Heisenberg which supposedly contains the first mention of "collapse of the wavefunction" and I found an incredibly insightful passage. Heisenberg muses about the transition from atomic electron orbitals to classical orbits and he writes: "Ich glaube, dass man die Entstehung der klassischen „Bahn" praegnant so formulieren kann: Die „Bahn" entsteht erst dadurch, dass wir sie beobachten.". In my translation this means "I believe that we can formulate the emergence of a classical "path" most significantly in this way: The "path" emerges only because we are observing it." He then proceeds to give a physical picture of what observation may do to an atom in a highly excited state (a so called "Rydberg atom"). In other words, intuitively Heisenberg already understood that the classical world is the result of continuous weak observation of quantum systems, something that Mott will explain with mathematical precision just a couple years later (1929) for alpha particle tracks in high energy particle detectors. This is still widely unknow and poorly taught in QM 101 classes, despite its almost 100 year history. I couldn't find anything in that paper that talks about "collapse of the wave function", so far. I need to read it, again.
    2
  1631.  @xiupsilon876  Yes, there has been a lot of theoretical research in that area and even Sabine Hossenfelder has recently published an article about a different type of "hidden variable" approach if I am not mistaken. There are a couple of problems with a phrase like "quantum mechanics is incomplete". What do we mean by that? Incomplete because we can not know position and momentum with arbitrary precision at the same time? That's not a quantum mechanical property to begin with. It's a general mathematical property of functions with L2-norm (that's what the mathematicians call "energy"). It's just as valid for water waves as it is for classical electromagnetic waves as it is for quark and gluon quantum fields. Wifi routers have a protocol that uses time-energy uncertainty to shape radio-wave packets in a certain way. Our engineers are using this principle in mechanical, electrical and information systems daily. This can never be "undone" because it runs into a fundamental mathematical property of continuous functions. If Einstein would have wanted that, then he didn't even realize that the classical world had exactly the same limitations as soon as continua were involved. Incomplete because photons, electrons etc. do not behave like classical particles? Absolutely nothing in the universe behaves like a classical particle. A classical particle in physics was always an abstraction to simplify problems like the Kepler problem to the level where it can be (almost) solved in closed mathematical form. All it ever meant was that we reduce the dynamics of an extended classical body to the dynamics of its center of mass, i.e. we neglect rotations and internal degrees of freedom. As it turns out, there are approx. one dozen single particle Hamiltonians that are integrable (that have general closed form solutions) and some of them (like the three dimensional Kepler problem and the four dimensional harmonic oscillator) are mathematically equivalent. Every other "particle problem" does not have a closed form solution and we can not predict its motion for arbitrary long times. If we connect three or four masses with rigid sticks and ask what the general rotation of these masses are, then it takes about a thousand pages of mathematics and physical discussion to sort out the possible modes of rotation of such systems under symmetry conditions and there is no solution for a completely asymmetric rotator, at all. That system is already completely chaotic. So what, exactly, are we losing in quantum mechanics compared to classical systems? If anything, the hydrogen atom is a much better behaved system than a general Newtonian rotator ever was. Finally, quantum mechanics the way Einstein saw it was not a physical theory. It was more like thermodynamics, a framework that connects different types of physical properties with each other but that does not say anything, at all, about a specific physical system. The physical theory that makes solid statements about nature is quantum field theory. It builds on what Einstein knew, but it goes far beyond it. Even Heisenberg mentions in that paper I just read that he does not believe (this is in 1925, I believe) that a quantum mechanical theory of the electromagnetic field is even possible. Feynman and others gave us such a theory in the 1948 to mid 1950's time frame, i.e. we went from knowing nothing about quantum fields to a complete (if unexplored) theory in another 30 years. That theory happens to be the one that has the best numerical match between theoretical prediction and experiment of all of our theories, to date. It's better than Newtonian mechanics/general relativity in the solar system by a factor of 100 or so, if I am not mistaken. So, then what does it take to make quantum theory complete? A predictive formula of when the next photon will appear in a photon detector? Do we have such a formula for the lottery numbers? The roulette wheels in Las Vegas? When two cars will collide the next time at any given intersection? Whether it will rain at 3:12pm next Thursday? If we do not have those predictors, then why does it bother us so much that they also do not exist for photons? Just my two cents.

  1636. That's correct. That's why the cosmological constant was mostly a curiosity outside of the steady state crowd which needed it to create a steady state model. Steady state doesn't agree with basically any observation that has been made on the universe, so the cosmological constant is kind of useless until you get to the precision cosmology stage, which really didn't happen until the 1990s. :-)

That's why one can't learn anything new about gravity by looking at that phenomenon. It only tells us what we already know.
    2
  1641. Yes, some people who do not know physics will say nonsense like that. People who do know physics will say the following "A monochromatic electromagnetic wave of frequency 𝜈 exchanges energy with an external system in quanta of energy 𝐸=ℎ𝜈.". No particles needed. Just used the correct definition for "quantum": "Quanta are small amounts of energy.". Yes, the energy of waves is NOT quantized. What is quantized are angular momentum and charges.

So while you may have tried to make a joke, you actually got it exactly right. The provably correct representation of software like a word processor would most likely really take an entire data center full of nearly random gibberish looking logical specifications. It's also completely irrelevant. You simply give the thing to the user and ask for feedback. That's the only practical way to test software.

  1646. If dark energy keeps increasing, then black hole lifetime is probably dominated by the increase and could be as short as tens of billions of years, if I remember some older papers correctly. Black holes gets "dissolved" by the ever higher negative energy density of dark energy, so to speak. If dark energy is really just a cosmological constant or zero, then black hole lifetime is really very, very long.

They will immediately feel that your company doesn't care about their concerns if you can't tell them a proper solution to their problems. If you want to work in an Indian call center, then BBA is probably fine.

  1660. You can find the ten dimensions mentioned in math books about Riemannian geometry. It's the number of dimensions needed to construct an embedding of a general metric in general relativity. It already seems to take at least six to make an embedding of a flat metric. These numbers are not surprising if you know a modicum about differential geometry. Why quantum mechanics should put away with them is not clear to me... since even the mean field theory requires this many.

  1662. While technically Sabine Hossenfelder's remarks are true, they miss the point about ITER. ITER is being advertised as an experimental plasma physics facility, not as an actual reactor. They write this on their own website: "ITER will not capture the energy it produces as electricity, but—as first of all fusion experiments in history to produce net energy gain—it will prepare the way for the machine that can." Also "The experimental campaign that will be carried out at ITER is crucial to advancing fusion science and preparing the way for the fusion power plants of tomorrow. " and "Harnessing fusion's power is the goal of ITER, which has been designed as the key experimental step between today's fusion research machines and tomorrow's fusion power plants." Nowhere does the ITER collaboration claim that they can make electrical energy. ITER is a science experiment that collects engineering data for future designs. That's it. Will there be future designs? Probably not using ITER's approach of bigger is better. That is economically simply not feasible. Future machines will have to operate with small plasma volumes at much higher fields (probably around twice of ITER's 12T field). Talking about that would have made for a much more interesting physics piece.
    2
  1663.  @eljcd  And they define for you what they mean by "net energy". They mean Q_plasma. Nowhere do they claim that they mean net electrical energy. So basically the ITER collaboration's true statements are presented as a false claim. That is insincere in itself. Now, maybe you are emotionally disappointed that eighty years of plasma physics research have not resulted in a working reactor... but that is your emotional problem. It is not a problem that the ITER collaboration has to solve with a giant magnet around a donut shaped vacuum chamber.

  1664. Sorry to hear that. Your experience matches that of my relatives. They caught a pre-alpha in 2020 and some of them described it as the worst experience of their lives. They got omicron a couple of months ago and everybody was really sick for about two weeks. It's nothing like a flu or a mild cold. One of them has long COVID symptoms in addition. He went from being healthy and fit (he did a 100km bike ride just shortly before he got infected) to having constant fatigue and pain. I wish you the best!

  1665.  @mightyblues7  I know a young medical doctor who had a case of a "mild" delta infection, but he caught it at work. I would assume that he took all the antivirals as soon as he tested positive, which would have been hours, if not days sooner than the average person. The young (in their early 20s) family members in my family complained about it being a horrible experience. The only really "mild" case for us was a less than one year old infant who had slight fewer for a couple of days. Yeah, sorry... the myth that "it's just a flu" doesn't want to go away, no matter how many people know better.

  1668. It's worse than that, actually. If you ask AI what the CAGR (compound annual growth rate) of automotive catalytic converter sales is, then you can get answers in the single digit and low teens percentage range. It should be obvious from the rapid growth of the EV market and falling ICE sales (they peaked in 2018, I believe) that this can not possibly be correct. So where does AI get these numbers from? It was trained on past sales data and commercial market reports that all showed positive growth and it is simply hallucinating continued positive growth based on that (nor irrelevant) data.

  1687. What is "forced conscription" supposed to be??? Military service is mandatory in many (if not most) countries. I have been in the military myself. Was it fun? No, of course not, but it was a necessary civic duty. Today I am looking back at the experience as something useful. It gave me an idea of "the other side of life". Even though the "fighting experience" was only simulated, sitting in the forest for hours waiting for a potential "attack" was nerve wrecking. I knew that had it been real, my life would have been on the line. A single shot by a sniper could have meant the end. Once you have that experience, paying taxes for an effective military feels a lot less of a waste than it might otherwise. The state and the men and women who are choosing to be in the military are putting their lives on the line so that everybody else can live in peace. They deserve the best weapons, the best protection, the best intelligence money can buy. Speak softly and carry a big stick is now more important than ever. We will need a much bigger stick in the future and many more soldiers. OK, champ?

  1688. This isn't news. It was obvious from the start that China didn't actually care about repayment. The main interest of the CCP was to keep the heavy industries of China going, even after the internal demand for steel and concrete began decreasing. They can slowly reduce them as workers and employees in these industries retire, but they need to close that decline-retirement gap to prevent tensions in their "harmonious society". Whether it will work is another question.

  1690.  @TheProf42  You can find ten dimensions on the level of pure differential geometry. It's the minimum number of flat embedding dimensions to describe a general metric. If anything then this makes string theory consistent with classical geometry/mean field theories of gravity. If that is what upsets you, then you just haven't read into the literature about Riemann manifolds deep enough. The reason why string theory doesn't connect to experiments are the experiments. We can't get beyond the 1TeV scale right now. That difficulty is the same no matter what quantum gravity model you prefer. Gravity is simply too weak at the 1TeV scale to make any measurable difference.
    2
  1691.  @TheProf42  We aren't living in four dimensions. We are living in three dimensions. Time is not a dimension. Never was, never will be. We treat time as a pseudo-dimension in special and general relativity because of the geometric relationship that governs free energy flow, which is what defines causality. The higher dimensions are occurring in these theories for mathematical reasons. They are not (and never were) believed to be observed physical dimensions. There are flavors of these models in which these could become real dimensions, but for that to happen we would have to see modifications to Newtonian gravity at short distances. We have done experiments at the mm and sub-mm post-Newtonian gravity scale that are ruling these models out. None of this is a problem except in your imagination. There are valid criticisms of string theory, but what you are listing here is just a misunderstanding of reality.

  1697. Energy is a scalar, it's just not a Lorentz scalar. Its the first component of a four-vector. The relativistic momentum are the other three components.
    2
  1698. Quantum mechanics is not about particles. It's about quanta of energy. It's a common misunderstanding based on poor language choices by the founders of quantum mechanics, but you can't base any criticism of QM on it. All it shows is that you don't understand quantum mechanics. Strings don't do away with geometry, at least not in any version of string theory that I am aware of. If anything that's a solid indication that string theory is, at most, a mesoscopic approach to gravity and spacetime in general.
    2
  1699.  @mikeanderson8158  The conserved properties of the vacuum are energy, momentum, angular momentum and charge. This is the combination of system properties that we call "quanta" and an event in quantum mechanics is the exchange of such a quantum between two systems. That such an exchange event has a duration is experimentally verifiable because it expresses itself in time-energy uncertainty. We can produce ultra-short pulses of light and the quanta in such pulses have a finite energy distribution that is inverse proportional to the duration of these pulses. The length of the time aperture of our energy measurement does influence the measured amount of energy. If we want perfect energy resolution, then we have to make that time window infinitely long. The same is true for momentum resolution. If we want to reduce the uncertainty in momentum to zero, then our detector system has to be infinitely large. None of this changes in string theory, as far as I can tell. String theory adds internal degrees of freedom to the physical vacuum that behave like compactified dimensions (at least that's the naive interpretation for some versions of it), but the structure of reality stay the same as in ordinary quantum mechanics, at least in the free field limit (which implies flat spacetime). It's not clear to me what field states in string theory mean for the strong field case, but that problem already exists in general relativity. Even classical energy density seems to lose its original meaning in strongly curved spacetime, so if the classical theory has that complication, then it will likely persist in any quantum model just as well.

  1700.  @LateNightRadioe  It is not even for Mark Zuckerberg to fix. This is exactly what government is for. We do not delegate social regulation functions to our industries. I think we can agree that setting limits is not an easy thing to do, but the majority of our citizens can probably agree on workable principles. Even staunch defenders of the right to free speech are rarely opposed to limiting the right to yell "Fire!" in crowded rooms in which no fire rages. If we can expand the definition of "room" to virtual rooms, then we will have made a significant amount of progress. Take care!

  1744.  @marcdb9974  It is not expanding into anything. The "volume" of space is simply not a constant. Why would it be? There is absolutely no identifiable physical reason for space to have a constant volume. That was always just an ad-hoc assumption based on local observation of solid matter at 300K. Does the universe behave like solid matter? No, it doesn't. There is no real mystery here, just old fashioned 19th century mechanistic thinking. Is it hard to overcome that kind of thought mechanism? Yes, absolutely, but a discussion of these old human habits belongs into the arts and humanities and maybe psychology. It is useless in physics. In physics when A does not behave like B, then the laws for A are not the same as the laws for B. Yes, it is that simple.

  1750. Superposition doesn't have a physical reality, it's just a mathematical property of the theory. What does have a physical reality is that qbits don't have any state at all until measured. It is NOT true that they have a classical state that just hasn't been revealed, yet. This is nothing special, by the way. Dice have the same property. Dice have a well defined state in the set of outcome states only while they are resting on the table. As soon as we are giving them non-zero kinetic energy in the rest system of the table their motion can not be described with one of the six outcome states anymore. So even dice don't have a state while they are still rolling. The situation gets worse in quantum mechanics because quantum mechanical systems are relativistic and their future depends on physics that in the present is happening in spacelike separated regions of spacetime. That physics is simply not defined in the here and now.

I am not sure it's all that effective against trenches, either, otherwise the US would not have signed Protocol III. We did, after all, also not sign the treaty against the use of cluster munities, which most likely means that our research suggest that cluster munitions provide much more bang for the buck.

He wants to leave his mark on the world, just like Putin. Let's hope he won't.

  1768. That is utter uneducated bullshit... which is common in the FOSS community. Technically neither Windows, OS X, Linux or Android are operating systems. They are all a mix of operating systems, file systems and higher level APIs, including graphics windowing systems. Things like file systems and graphics have absolutely nothing to do with OS services and one can even argue that an OS should not even be defined by its scheduler or its threading implementation. A "pure" OS simply gives access to machine resources to user programs that request them. It is, at the core, just a hardware arbiter that abstracts the actual hardware driver level away. This definition works well for mainframes and for microcontrollers, but it doesn't do much for desktop systems. To the average user and even to the application programmer a "pure" operating system is completely useless. It is far too low level an abstraction to be even borderline functional. What is therefor commonly referred to as an operating system is a whole slew of higher level functions that are sufficient to develop complex applications. One of the problems with Linux is that it packs too much higher level functionality into the kernel while it concurrently fails to provide a well designed and high performance set of APIs to the application programmer. It therefor satisfies neither the academic nor the popular definition of an operating system.

Iranians are master politicians. They know how to play everybody but they don't want a war that they can't win.

  1779. Nuclear weapons are not as hard to make and maintain as you think. Once you have the base technologies it's rather easy. So, yes, they do work. Maybe not all of them, but you still don't want to see a war with even 1000 working Russian nukes.

  1780. A sex worker is not a substitute for what most people are actually looking for, which is love and company. I used to live next to the red light district in a European city for years. I was addressed a couple of times by one of the women on the street (which was an unlawful act at the time in that country). No matter how lonely I felt, I never even thought about soliciting their services. If anything, I found the idea extremely off-putting.

  1782. This is not a free market problem. This is a drug development cost problem. If you look at the actual margins of drug companies, you will notice that they are in the low percent to low teens range. It's a very hard business model. How do you know? You aren't making any. If anybody could make drugs like housewives are making candles and soap, then you would, too.

  1783. Not sure what you mean by that. What has affected your life is the choice of people that you let into it. It's not their fantasies or the industrial exploitation thereof. Just because somebody gets aroused by a blue painted pig in sunglasses does not mean that they will act on that. If anything, the internet has become a formulaic depiction of rather boring tropes about human fantasies, just like Hollywood and its superhero movies. Do you know why? Because depicting real human intimacy is extremely difficult. Only the best of the best writers can even come up with a believable and arousing dialog between two people. Only the best actors can make such a dialog work. It is almost impossible to act it out in a horizontal position. Just to give you my experience with the subject: the most loving thing anybody ever told me were exactly five words. Those five words, spoken at the right time, have kept me warm and happy for a lifetime. What matters, and this is the only thing that matters, is that you can find the one person who can utter YOUR handful of magic words in the right moment. Everything else from there is easy, no matter how many petabytes of poor examples of human intimacy you can find on the internet.

  1796.  @Redflowers9  The basics of evolution haven't changed, either. We understand the genetic component that leads to the variability of a species better, but the natural selection part which drives adaptation and speciation is virtually the same. The beauty of Darwin's idea is that it doesn't require a microscopic understanding of the underlying biological mechanisms. He could predict the existence of a moth with a very long proboscis just by finding an orchid species with a very deep nectary. That moth was discovered just recently if I remember correctly.

  1797.  @BloggerMusicMan  A government that makes its own currency can not run out of money. It may run out of good uses for that money, but the money itself can never be a problem. Compare that to governments that are not in control of their own currencies like Greece. You want to emulate that sh*t show? Why?

  1798. Conservatives need to get a life and vote these clowns out. If whoever is running in your district is anything but an up-right adult, sit out the election. Just don't vote for a person who hates their country. It's that simple. Until you do that, the GOP will never change.

  1800. Not in the past. They expected a WW II style "Aufmarsch" of a massive tank army with a week long "Blitzkrieg" and that is exactly what Russia tried to do. It failed completely because this isn't WW II any longer. Today every monkey on the battle field carries an anti-tank weapon with a very high success rate. Running armor against a well trained and armed infantry is suicide. Tens of thousands of Russians literally burned because of their foolish choices. The tree line conflict only emerged as a fallback solution because any level of material concentration is basically just a pair of firing coordinates coming directly from a satellite to an artillerist. BOOM... :-) So what is the solution? For Ukraine it's the development of an air force of drones that can be used to eliminate soldiers at the individual level cheaply. Small "boom" and soldier is still kaput. :-)

  1801. Talent is nice and well... but if the man it's attached to is burned out, then the talent usually goes away rather quickly and is replaced with increasingly more bizarre decision making processes. One has to accept that Musk's flame, which shone oh so brightly, might be coming to an end.

  1810. That's the misunderstanding. The box symbolizes the complete isolation of the free quantum system. What's in it is entirely irrelevant. It's still being described by a quantum mechanical equation WITHOUT outcome. The outcome always requires a system that is OPEN to a measurement device. I don't believe Schroedinger understood this and his cat doesn't make it any easier to "grok".
    2
  1811. One can easily make a source that can only emit a single photon: trap one atom in a Penning trap. Excite it to one of its optically unstable states and let it decay into the ground state. Voila. Exactly one photon. Having said that, your problem is that you simply don't understand why the number of photons in such an experiment is completely irrelevant (because of linearity).
    2
  1812. Don't know about a couple of months, but eight of my relatives had it twice in about a year and a half and another couple had it for the third time now (he has long COVID in addition), so whatever immunity people get from an infection, it doesn't seem to last significantly longer than for e.g. the flu or the common cold.

  1814.  @Orlandofurioso95  But what makes you think that this is "the right thing to do" in the first place? Every time somebody gives you a recipe for success they a) limit your options to find a better solution and b) hand you a recipe for disaster, if you fail to apply the assumptions that make it a potentially good solution for SOME problems.

  1818. There are no particles in quantum mechanics. There are only quanta of energy. We are trying to teach this in high school, but most people aren't listening. So what is a quantum? It's the amount of energy that gets absorbed by the detector. Without that absorption process there simply is no quantum. This paper is part deception (the definition of a bomb implies that an active one is an absorber, but an inactive one is transparent), part quantum mysticism (quanta are endpoints, they don't have paths) and part interesting (it gives a simple example for weak measurement ). I would take the last part and forget about the first two.

  1819. I had mononucleosis as an adult (I sipped from the wrong cup at a party... I didn't even get it through a kiss...). Boy, that was a rough year. I had to take unpaid time off from work because I was basically useless in the office. I had a good employer at the time who was willing to pay me for the hours I was in... but that was not fun.
    2
  1820. Vaccines work two ways: they reduce mortality in those who get them (and that worked nicely) and ideally the disease can't spread in a fully vaccinated population. The last thing didn't work because too many people are not getting the vaccine. Of course it's those who didn't get the vaccines who are dying now... karma is a you know what.

  1831. It sounds like complete nonsense because it is complete nonsense. Everett simply didn't understand that quantum mechanics is an ensemble theory, i.e. it describes frequentist averages of infinite repetitions of the same experiment. In practice there are no ensembles. All our measurements are finite. Moreover, we usually do not build more than one copy of the same experiment. We simply reuse the same setup over and over, again, hoping that it shows no "memory" effect, which would require the use of different formulas than those in quantum mechanics.
    2
  1832. @ If it looks like that it doesn't make sense then it is because it doesn't make sense. The universe does not have a wave function and there is only one universe. The wave function is a mathematical abstract that gets created by a divide and conquer methodology that assumes that experiments are infinitely repeatable AND that all of the repeats are independent. That assumption simply does not hold for the universe. It's actually worse than that: the universe is not even a system, so almost none of the assumptions used in physics are valid.

  1835. This is not overproduction. This is a jokester who wanted to know if the journal will publish completely random rubbish... and the journal did, probably without even checking if the authors actually exist. It's a pretty trivial test for a journal. If this gets published, then you can forget about the entire journal content because ANYTHING will get published.

  1836.  @gammakeraulophon  If it looks like a joke, then it is a joke. No theoretical physicist will write nonsense like this, at least not if they didn't have a stroke or have taken a mixture of LSD, meth and cocaine with a good dose of horse tranquilizer for dessert. ;-)

  1837. Marxism has failed. The end.
    2
  1838. @ayy lmao Let's make this simple, kid. Let's use the conventional definition of Marxism as a method of socioeconomic analysis that uses a materialist interpretation of historical development, better known as historical materialism, to understand class relations and social conflict as well as a dialectical perspective to view social transformation. As such it has made predictions about the future from the perspective of the 19th century, correct? All of those predictions have failed. Now, we can discuss why predictions, especially of the future, are difficult. What we can not discuss is that Marx and Engels were simply wrong. The dominating forces of the 20th and 21st century are certainly not those of historical materialism. They are mechanization and automation (devaluing manual labor of the kind that Marx saw as a dominant form of influence), information technology, nuclear energy (in form of nuclear weapons), the aging of the world's populations and, soon enough, artificial intelligence. Marxism was completely blindsided by all of these. The end.
    2
  1839. Why are you telling us that you don't understand physics? ;-) Tsiolkovsky, Oberth and Goddard did their work before and during the development of quantum mechanics, by the way. Even your science history is wrong. Spaceflight appears in fiction (e.g. Jules Verne) way, way before quantum mechanics was even considered theoretically. :-)

  1841. People have been growing up with substitute parents since we came down from the trees. In the deep past Dad went hunting and Mom was gathering all day long. Then they were both slaving away (literally) on the fields that belonged to a rich man. Since the industrial revolution both had to work in factories etc. to make a living. My substitute parents were books, the radio and the tv set. I turned out OK. My parents only have high school diplomas, I have a PhD in physics. Whatever these people are telling you about kids not being able to cope with Mom and Dad not being there all the time is utter bullshit.

  1851.  @ruthlessoptimism1106  Whenever somebody says that the wave function collapses you can stop listening. That person doesn't understand physics. The wave function is an ensemble average, like a probability distribution. When you roll dice their probability distribution stays exactly the same, no matter the outcome. The same applies to the wave function of a quantum mechanical ensemble. It's always the same and completely unalterable.
    1
  1852.  @ruthlessoptimism1106  A photon is the quantum of energy that a detector absorbs from the electromagnetic field. There is no such thing as a photon without that absorption process... so, yeah, if you pay attention in high school when they teach the photoelectric effect, then you won't be surprised about such a triviality. It's basically the definition of "photon". :-)
    1
  1853.  @ruthlessoptimism1106  There is no assumption of randomness in quantum mechanics. The assumption behind the math is independence. Whether a series of measurements is independent is easily testable with well known statistical tests like correlation functions.
    1
  1854.  @ruthlessoptimism1106  There are no particles in quantum mechanics. There are only quanta of energy. You aren't listening. ;-) A series of measurements are independent if the (n+1)th measurement is not correlated with the previous n. You were clearly not paying any attention in high school math, either, when they explained trivial statistics to you. ;-)
    1
  1855.  @ruthlessoptimism1106  You calculate the correlation function. If it's zero, then the measurements are independent. A typical example would be radioactive decay. You won't be able to predict when the next nucleus decays from the previous n decays. If you were to measure the arrival times of photons from a laser, however, then you would find them highly correlated. In that case using a one-quantum wave function is simply not enough to characterize the laser's system. These are not assumption. They are experimentally testable properties of series of observations.

    1
  1858.  @ruthlessoptimism1106  That is correct. A photon is ONE outcome. Just like the number "3" is one outcome of a dice roll. What is the deep question here? :-) Or are you under the impression that quantum mechanics predicts single photons? No, of course not. Nothing can predict a single photon. That follows trivially from relativity. :-)
    1
  1859.  @ruthlessoptimism1106  If you are measuring a double slit pattern you are not measuring one photon. You are measuring many photons. It seems to me that you are also having trouble distinguishing between "one" and "many". There is an episode of Sesame Street where Ernie and cookie monster are demonstrating the difference between one large cookie and many small cookies. Might be worth re-watching to get the basics about the difference between "one" and "many" grounded. ;-)

  1867. Then we should be debating the merit of tenure (which I am critical of myself), but what does that have to do with Sabine's false explanations about quantum mechanics, special relativity and string theory? Now, let's say you remove tenure, how does that change the dependence of students on their advisors? The advisor is the person who brought the grants in to do the research. If a grant approves X, then the advisor is required to have a student do something that is at least closely related to X. You can't just take that TAXPAYER money and do with it whatever you want just because the student feels like doing something else. Unless, of course, you will require students to bring their own grant money and lab equipment. Now that will be interesting, won't it... then only the 100 times millionaire and billionaire kids will ever get a PhD. ;-)

  1873. How many versions of the same product are you going to release? 18? In that case you need reuse. If you don't, then reuse is of absolutely no concern. It will weigh you down and you will never ship a product. Separation of concerns has to do with the structure of your problem (data entry, data storage, filters, search, output generation). Can it be factored into the completely independent solution of partial problem? Modularity is an implementation strategy. Even if your problem factors, the single solution may still require too much code to be implemented monolithically and you have to break it up into loosely coupled modules.

  1878. Huawei stock is registered to an internal organization within the company, not to individual shareholders. That's a very common scam in China. Companies force employees to buy their own shares, but they are not actually given ownership of those shares, instead one person (usually one of the managers of the company), keeps the shares locked up under his name. The actual employee never gets to exercise those shares. Anybody who tried that scheme in the US would immediately go to jail for securities fraud.

  1879. Testing was never important. What is important is the number of people that have to be hospitalized. What testing can do, at most, is to produce a one to two week prediction for the number of hospitalizations, but it won't reduce it, nor will it change the idiotic minds of most politicians. Once a government decides that it doesn't care about the breakdown of the healthcare system, testing is all but irrelevant. China has given up on rational measures, hence it does not have to test people.

  1884. The Twitter acquisition was certainly a grand mistake. I am pretty sure even Musk feels that way by now. Based on the news he was actually trying to wiggle out of it, in the end, but he had signed the contract, already. That's a real problem if you are operating under American laws. Unless you can prove that you were under the influence when you signed a US contract is like god and it shows no mercy. With regards to Ukraine... I kind of doubt that SpaceX does anything without the direct support/supervision of the State Department and the Pentagon. Again... the US has a very strong legal regime in place for the kinds of assets that SpaceX has.

  1898. Russia has nothing to do with it. SpaceX is legally forbidden from supporting foreign governments without explicit permission of the US government. What Elon Musk wants or doesn't want is completely irrelevant here. What they can and can not do is all covered by US laws.

  1899. Free will is just another bullshit concept that philosophers came up with. In a religious context it's just a failed attempt to solve theodicy. No child has to die in a cancer ward to make sure that I can pick between chocolate and vanilla. Try again. This time using intelligence. ;-)

  1900. In my family the statistical evidence is as follows: everybody who has been vaccinated with Moderna or Pfizer didn't have COVID-19 even once. The eight antivaxxers in the family had it twice and a couple who were vaccinated with sinovax had it three times, already. One person has long COVID-19 symptoms.

  1907. Yes, just not in such quantities and probably at a significantly higher cost.

  1908.  @Cooe.  Intel can't sell chips "at cost". Intel has to make chips at a profit. Dude... Intel and TMSC revenue are similar, but Intel sells considerably more expensive products, hence it doesn't need as much fab capacity. By EUV lithography machine count TSMC seems to be leading by a factor of two.

  1909. In theory, yes, but in practice they are the first ones to be destroyed in case of a revolution. The political instability of Russia is the result of the total destruction of its middle class during the Russian Revolution and following decades. There simply are no serious, level headed political stakeholders left in Russia. There are only psychopaths and their victims. You can see similar trajectories in Mexico, South America and Africa.

  1925.  @Qvcpvc909  Unlike you I am not a sucker for idiocies, so why would I take a bet that I am guaranteed to lose? Would you like a Pascal's wager with that? Better start praying to the FSM or you will have to spend eternity as a meat ball. :-)

  1933.  @NerdyEngineer  Because of immigration. Immigrants are paying into the system and taking the least out of it. It's the old middle class people who are the takers, i.e. the baby boomers right now. They are the sole cause of the budget shortfalls. And that's OK. We are humanists. We don't abandon our old folks in the desert to die alone so that we don't have to take care of them. :-)

  1945. You are absolutely right except for one thing: photons don't hit your eyes, they are the amounts of energy that get absorbed by your eyes. The may sound like a trivial difference, but it's the key to actually understanding quantum mechanics. There are no photons in the free field. Quanta are not atomistic phenomena.

  1959.  @metalpuppet5798  This is what really upsets me. The same people who have a lifetime of experience with flu and the common cold, neither of which humans have any level of "natural immunity" to, are claiming that this respiratory disease has to be magically different and disappear on its own. There is absolutely nothing in any of the data that we have seen that would indicate that COVID-19 won't cost millions of lives every year going forward, unless we actively prevent it from killing us.

  1961. Congress isn't funding untested arms here. The new fleet of spy satellites that is being launched by the US government is choke full of technology that has been financed by Congress and tested over the last 30 years. The concept of flying large constellations of cheap satellites has been sufficiently demonstrated by SpaceX. Did you ever spend a waking minute on asking the question what the US government needs a 150ton LEO payload capable, rapidly reusable rocket for? It is, for sure, not to launch another weather satellite to monitor global warming. The motives here are much, much more sinister and they have to do with a credible replacement for the aging nuclear bomber and ICBM fleets. We are building a space based nuclear deterrent system right now, for those who can't complete the thought that I have just outlined.

  1964. If you are simplifying aspects of the real world you end up with non-working software. You first definition is already total garbage. Encapsulation doesn't have to mean data and methods. In any case that exists only on the code level. It does not exist any longer at the machine level, your compiler strips all that bullshit out of your code anyway. If you want to truly encapsulate at the machine level, then you have to write very specific boundary checking code. Inheritance is interface reuse, not code reuse. Integers, floating point numbers and complex numbers have the exact same algebraic operations (methods), but the formulas for these methods are vastly different. Your compiler can't know that. Only children who have never seen a floating point library before floating point hardware became standard in CPUs don't know this.
    1
  1965.  @TonyTigerTonyTiger  No, kid, that is not what an abstraction is. The whole numbers are an abstraction. They don't simplify the real world in which there are only countable items. Instead they remove the limitation of countability completely and are opening up reasoning to abstract processes like infinite limits. Computer science is simply full of people who have absolutely no clue about either the world or the structure of intellectual thought, not even at the high school level.
    1
  1966.  @TonyTigerTonyTiger  I am not writing OOP at all. I don't have to, since I am the only developer on my own projects. I don't have a need for that kind of documentation. My software design starts with an interface definition. THAT is the world the code lives in. Your rental care company software doesn't know what "car" is. You can call it "tree" or "thing" or "AA", like in the good old times of 8K BASIC with its two character limit on variable names. What you are really doing with classes for "car" and "truck" and "vehicle" is to make it nearly impossible for your user to describe something that your architect hasn't foreseen in his infinite wisdom (he is god, after all, at least in his own mind). So every time that something comes up that architect god didn't anticipate your developer team is screwed. Now all of you have to refactor the hell out of it OR you have to completely ignore what the "car" class was supposed to mean and you write a "reservationForCustomerFlightNumber" method into "car", which links the "car" database to the global airline industry. Damn, doesn't that feel good? :-)

You can easily train an LLM on data the says the Tuesday is only half as long as Monday and that the sky is green on December 12th, but only if the cat had four kittens in May and the LLM will reproduce these "facts" perfectly. They are thus perfectly designed to spread fake news. :-)

Tough luck for the previous renters.

  2036. They were no better in the 1950s and 1960s and the Russians still beat the US to space and they had a reliable nuclear arsenal back then as well. The corruption and incompetence card only gets you this far. It does not win you the game. Would Russia lose in a direct conventional confrontation? Absolutely. But this one isn't. Even if only 1% of the ICBMs targeting the US could deliver a working warhead we would have tens of millions of casualties in the US.

  2040.  @nickmontanaro9638  "Particle physics" is a misnomer. It's properly characterized as "high energy physics" because it is all about energy. There are no particles there whatsoever. How do I know? I used to measure that energy. I have NEVER measured even a single particle. ;-)

  2042. The difference is not in a single bit/qbit. It's in how the total number of operations scales with the number of bits/qbits. If n is the number of bits/qbits, then the machine state/number of operations the machine can do goes with O(n) for a classical computer, but O(exp(n)) for a quantum computer.

  2045. There is no big difference. OOP is basically a syntactically nicer form of typedef for structures that also contain function pointers. Much of what you can do with one you can also do with the other. The compiler will handle name spaces and access rights for you, which leads to a perception of more "security" in statically typed languages. In dynamic languages like Python you don't even get that.

  2048. Do what university students do: learn in a group. Chances of finding somebody who already has a particular concept figured out are fairly high in a group. That student can explain it to the others and other students will know other stuff in return. That way you are all learning together how to explain these concepts better to yourself and others. Sharing also makes it easier to remember the material.
    1
  2049. I have never seen "multiple possible timelines" in QFT. Where did you get that from? There is no detector problem. "Detection" or "observation" is merely an irreversible energy transfer from the quantum system to an external system. There is absolutely nothing difficult about it, either philosophically or from a physicist's point of view. A good detector for photons has to be "black" in the spectral range of interest or it will simply not absorb the photons. A good detector for electrons might be shielded with a dedicated field grid that prevents them from leaving the collection anode. Physicists deliberately engineer detectors to be close to ideal thermodynamic absorbers, i.e. we know what we are trying to achieve at the level of experimentalists. No additional theory needed.
    1
  2050.  @jth4242  Feynman diagrams are not representing physical processes in a spatial representation. That's just a trivializing explanation for the masses. The physics is in the sum of an infinite number of these diagrams, most of which will actually cancel out in well defined quantum field theories. Either way there is only one "timeline" in these diagrams because we are working in a single (relativistic) frame. Nature does not do any of what is going on in these diagrams, to begin with. They are an artifact of a quantization procedure (path integrals) that doesn't give us many good options to actually calculate theories with interaction terms. The infinite nested integrals that result from it can only be solved in closed for for gaussian wave packets, i.e. non-interacting systems. The interesting case requires a perturbation procedure which leads to non-physical "virtual particles", none of which can ever be observed in nature. I believe that they have found some interesting internal symmetries of this mathematical problem lately that allows shortcuts for these calculations in some cases (see "amplituhedron"). That may get us finally going in the right direction to understanding what the actual physical structure of quantum fields are.

  2051.  @jth4242  I didn't say that it's impossible to derive actual physical "elementary processes". What I said is that Feynman diagrams are not equivalent to these processes. That does not mean that there are no other representations of the behavior of quantum fields that can yield a much better interpretation. Personally I strongly suspect that there are and I gave you an example of recent theoretical insight into one possible such avenue. The problem with Feynman diagrams is simply that they weren't derived from physical insight but they are a purely mathematical necessity to get through the calculations in a naive way, at all. Why are Feynman diagrams like that? Because the path integral formulation of quantum mechanics, which is a quantization procedure, basically assumes that one can describe the world in terms of quanta, which are irreversible energy exchanges at the boundary of a quantum field. By pushing this irreversibility (that does not exist there) into the volume, we are opening up a whole slew of mathematical problems, which we then have to solve with more or less ad-hoc methods. Even our best solutions have remnants of trouble (like an extremely high calculated vacuum self-energy term) that do not exist in nature. In nature quantum fields behave like extremely smooth objects all the way across the universe (if they didn't, then we couldn't see all the way back to the beginning of time with telescopes). There are no dizzying virtual particles popping in and out of existence all over the place as poor visualizations of spacetime want to make you believe. Atoms in the ground state remain in the grounds state until actively excited etc... all of this tells you that something in our math is wrong. It's good enough to calculate a lot of things, but it's still not good enough to be satisfied with it. And we aren't. That's why very smart people are still thinking about the problem. QFT with Feynman diagrams is, by far, not the last word, neither mathematically nor in terms of physical interpretation.

  2052.  @jth4242  Religion is the occupation that tells you about events that didn't happen. Physics tells you about physical dynamics that can not be described in terms of classical events. I don't think you should rely on Sabine Hossenfelder too much in this area. She seems to have fallen into a rabbit hole about quantum mechanics herself.

  2053.  @jth4242  I am an experimentalist. A theory has only one function: it has to describe everything that is experimentally and observationally accessible within its range of application. If it does that, it's all good. I do not need a philosophical layer with imagined additional requirements of beauty, "realism" or whatever fancy ideas philosophers who have never set foot in a lab may assert to insert themselves into my ballgame. That's the same "attitude" that you will find in NFL coaches and players with regards to armchair coaching. Either you are willing to play or you are not. Either you take the daily punches of the game or you don't. If you don't, then please stay away from the field. That's not a statement about you personally. It's a statement about "philosophy" in science.

  2054.  @jth4242  Does the accreditation of the author decide about the quality of a paper? No. In physics the experiments and observations decide. If you don't like that rule, then physics and science in general are not the right games for you.

  2055.  @jth4242  Where did I introduce an argument of authority? Nature is the only authority in science. Either a scientist can correctly describe nature or he/she can't. Everything else is silliness. At this point I think you need to go back to basics.

  2058. @Imjust Observing Nature doesn't know about systems. The physicist defines them at will. We simply have to verify that they behave like the way we say they do. You are correct, the entire universe is just one quantum field, but much of it behaves classically for the purposes of physics. The trick is to know when, where and why.
    1
  2059. @Imjust Observing Violation of any of the conservation laws. I don't know if you guys are aware of this (it does not seem you are), but an atom has to be brought into an excited state to release a photon. That means that a mixed state between exited and ground-state is simply some of the ensemble being in the excited state and some of it being in the ground state. The same atom, however, can never be in both states at the same time because that energy will, eventually, have to be released. Energy that is not in the system can not be released. Energy that is in the system can not stay in it forever because of the decay time constant. Goodness, gracious, kids. This ain't rocket science. One simply has to be able to distinguish between ensemble properties and individual system properties. What QM can't tell us for mixed states is which of the actual states one particular atom is in, that's all. This does have severe consequences for the phase space of systems that have many degrees of freedom, but even for those the total energy is the total energy, no matter how much it spreads out over the mix. You can make the same argument for any conserved quantity. Momentum, angular momentum, spin, charge, lepton number, whatever. These conservation laws are not just being obeyed in the average. They are being obeyed by any one of the samples in the ensemble. To think otherwise is unphysical. Maybe you really need to take a few lab classes in the atomic physics department to remind yourself how nature actually works. That is the problem with all this double slit nonsense and Schroedinger's cat etc. These toy examples do not force you to think about real physics. They all gloss over all the stuff that is of actual importance in real world experiments. Do you really think we would build a multi-billion dollar 17km circumference accelerator if protons would be equally likely in all possible momentum states????? Seriously? End rant.
    1
  2060. @Imjust Observing Single protons don't have any uncertainty. We have to measure the momentum of many protons to calculate an uncertainty.
    1
  2061. @Imjust Observing Rationalism in science means that you describe what you measure. I, for one, have never measured a wave function and certainly not on a single system. When I measure a single photon, I get one energy value, one momentum value and one spin value. That's it. That is rational. Whatever else you think there is to it is entirely a construct of your mind. It does not have an equivalent in an experimental setup.
    1
  2062. @Imjust Observing There are no operators in nature. That's formalism. In nature you can measure a few physical quantities at a time on quanta. Which quantities those are is given by the symmetries of spacetime (or, if you make e.g. 2d systems in solid state experiments by those local symmetries). When you measure photons you get energy, momentum and spin. An electron throws a a non-zero electric charge and a lepton number in there for you. Have you ever done actual measurements on quantum systems? There are no operators involved. It's all metal, vacuum, electric fields etc..

  2063. @Imjust Observing With regards to "collapse"... can you give me the experimental apparatus design to measure collapse? I have never seen a "collapsor" in my life. Not at CERN, not at atomic physics labs. It wasn't shown to me in my lectures on quantum mechanics, either. It must be a very rare apparatus, indeed, because no physicist I know personally has ever seen one, either. It's almost like the Santa Claus sled of physics. :-)

  2091. I don't know how much experience you have with relationships, but an adult male in a working adult relationship does NOT crave intimate experiences the way a teenager does. This doesn't mean that we aren't craving intimacy. We are. What we are NOT craving, however, is the enormous amount of emotional (and sometimes physical) effort that is required to have a truly good intimate relationships. And THAT Is the actual reason why infidelity is not a problem for "happy" couples. We know that the fantasy of a quick in and quick out does not exist in the real world. Why do we know that? Because it may have taken us many days, weeks, months or even years of work to build a truly intimate relationship with our life partners. A real partner is the biggest investment you will ever make in your entire life. If you don't know that, yet, then you didn't have a real partner, yet. Words like "entitlement" are therefor pointless. They lead into the void, not just in practice, but also in theory. "For better or for worse", as trite as it is, is a much, much better way of thinking about this. Somebody who can't swallow the "for worse" part is, at the end of the day, not a suitable choice of a partner.

The wavelength of these flavor changes varies with energy.

The world is, indeed, structured as if it was made of absolutely nothing.

If the answer is negative, then you should leave, but it doesn't have to be tomorrow. Give it a couple months. 3) Am I making enough money? If the answer is no but you aren't starving and you are happy and you have growth opportunities then maybe you shouldn't leave because you might find that the next place will have negative answers to questions 1) and 2).

  2111. The universe is, by definition, the one and only collection of all systems. Energy is only conserved in systems that have time translation symmetry. Spacetime does not have this property at large scales. The only reason why energy conservation is so appealing to you is because we drilled it into you in high school without explaining the details properly. It was a lie of mercy to a teenager who wasn't ready for the truth, if you like. If you want to understand "the real universe", then you have to learn the details and you have to let go of the "energy conservation" holy cow. The world simply doesn't work like that IN GENERAL, even if it does work like that when you have to pay your electricity bill.

  2115. @ We most likely had the correct theory since at least 1630, latest. That's when Galileo formulated a modern example of the relativity principle in form of Galileo's ship. The relativity principle spawns both quantum mechanics and general relativity in a mathematically pretty stringent way. It simply took over 300 years for us to develop the necessary mathematical tools to see that. What it does not do, is to prescribe exactly one solution for the universe. We can derive the "current solution" from anthropic principles (and have been doing that since the 19th century, even in classical mechanics), but we are still lacking at least one theoretical ingredient to select the current solution among the possible ones. So what we are lacking, right now, is not the unifying principle. That's the most trivial thing of all (and that's why it gets overlooked by virtually everybody, layman or specialist). We are lacking the mathematical tools to further explore the consequences of relativity and we are lacking empirical data. What you, personally, are "missing" is simply the education that would make all of this crystal clear to you.
    1
  2116. @ BTW, what makes general relativity "incompatible" with quantum mechanics are two fundamentally flawed assumptions: 1) The equivalence principle is simply false. It is only a good approximation in the absence of forces. As soon as the tiniest bit of electromagnetism rears its ugly head matter does NOT behave independently of its chemical and nuclear composition. This is the reason why microscopic gravity measurements are so incredibly difficult. Electromagnetism completely swamps gravity. 2) That general relativity is a well verified theory. It isn't. General relativity is an effective classical field theory, which is completely unverified except in the approximation of large distances (compared to the electromagnetic, electroweak and color scale). It may or may not hold below roughly 0.1mm and even at the scale of 1m we only have tests for its Newtonian approximation. The smallest known weak field test case for general relativity is roughly the scale of Earth. If you had taken some time to study physics all of this would be obvious to you.

  2200. Measurement isn't probabilistic, either. It's uncertain. One can simply not predict the result of the next measurement locally. This is caused by relativity. The second component that determines the physical structure of the theory is cause by angular momentum and charge quantization, which are also caused by relativity, but I am not aware of a simple intuitive argument for how one can understand either.

  2233. These local heat effects are not completely trivial, but they are not responsible for the majority of the warming. Local evaporation does not remove heating from the atmosphere. It actually makes things worse because water vapor is a strong greenhouse gas. That's easily experienced by comparing humid and dry environments of equal temperature. In a strongly humid atmosphere infrared radiation is coming from all directions and not just the direction of the sun because humidity in the infrared acts like a thick fog. That is one of the reasons why dry heat is easier to bear than humid conditions.
    1
  2234.  @jpp9876  That's a common misconception coming from biology. From a physical perspective a completely dry body will still receive more infrared radiation from the surrounding water vapor in a humid atmosphere than in a dry atmosphere. The role of the atmosphere for radiation transport is poorly understood by most people. We are not teaching this correctly (if at all) in school.
    1
  2235.  @jpp9876  What does radiation transport have to do with statistics? It's basic physics. I would suggest you look for papers about "radiative sky cooling", which is an engineering topic completely unrelated to climate science. That should take the political bias out of the equation. Here is one: "Radiative cooling resource maps for the contiguous United States" J. Renewable Sustainable Energy 11, 036501 (2019). You can find plenty of other resources like that with diagrams and formulae for the dependence of radiative cooling on atmospheric humidity.

  2244. I don't agree with most of the things philosophers are saying, but Sabine's stance is neither representative for physicists in general nor does it agree with natural observations. Indeed, one of the prerequisites of doing science at all is that we can relatively freely choose what to observe, when, where and with what tools and techniques. We need the freedom to compare and discuss such observations amongst ourselves and we need the ability to change our minds if we encounter better arguments or data than our own. Take any of that away and science can't function.

  2245. Maybe, but you were simply too young to understand that many of those stories were actually motivated by the politics of the day. That doesn't make them any more true, of course, but still, they are not simple confabulations. Many of them were probably very carefully devised religious-political statements. That did, of course, not stop the Romans from razing Jerusalem, anyway. The only political statements the Romans were listening to were the ones that were pinned to a Roman legion's banners. The Jewish folks were simply out of luck... they didn't have anything that could stop a Roman legion. Stories about a vengeful god certainly didn't give the Romans more than a loud laugh.

  2258.  @ascohn  I am simply pointing out that mentioning physics and philosophy in one sentence is a poor mental habit of the past. If that is similar to your position, then we are in full agreement. It is, of course, a historically common phenomenon. Planck, Einstein, and even Heisenberg who should have known better (and based on his own scientific writing actually did know better when he was young) and numerous others have been setting the public perception of science back over and over again be referencing completely unnecessary philosophical ideas that have nothing to do with proper scientific reasoning. My attitude is not pointless. We have known what drives quantum mechanics for almost a hundred years now but the way we are teaching this absolutely trivial subject surrounds it with an almost occult aura of deliberate obfuscation. This has to stop. This isn't religion. Everything here can be deduced logically from very simple first principles (ultimately it all follows from Galileo's relativity principle published in 1630!) and nature happens to agree with the result of that reasoning with absolutely astonishing precision.

  2327. Cool topic and I admit that I didn't think about it like that, either... but I always arrange my data in arrays if I can. That includes the way I define objects. If "some thing" has to do the same function a lot of times, I allocate arrays for the data. The main reason why I do this is memory layout. By pre-allocating a fixed memory block and checking range all kinds of nasty dynamic bugs can be avoided because the system always knows how much memory it has left.

  2329.  @RobertoLopez-nn8ty  Well, the US has three quarters of an ounce of gold in storage for us per person. Currently that's worth about $1500, right? So what happens a week from now, when that gold runs out? :-)

  2330.  @RobertoLopez-nn8ty  So what you are really saying is that you were foolish enough to buy some gold when it was sky high and now you need a stupid monetary scheme that will never happen to bail you out. :-)

  2331.  @RobertoLopez-nn8ty  Gold is a dense, soft, yellow metal with limited technological uses. It costs $400-1200 per ounce to mine. That plus 15% profit for the miner/refiner is the target price for a rational user of gold.

  2333. A measurement in physics is an irreversible energy transfer. You weren't paying attention in undergrad physics. It's usually defined that way in thermodynamics/statistical mechanic courses when thermal noise is being discussed. Admittedly, my professor may not have spent more than fifteen minutes and one or two classroom exercise problems on it, but why would he have? It's the most trivial piece of physics there is. If you can't figure this out on your own, then science is not a good match for you. Superposition is a CONSTRUCTED mathematical property of the theory. It follows trivially from the requirements that members of the quantum mechanical ensemble are statistically independent. That's also something you should have been able to figure out on your own even if nobody ever told you about it. Where else would perfect linearity come from in nature???? It has to be a mathematical rather than a physical property.

  2338. This is more about finding ways of describing unitary dynamics of black holes than anything else. That all "real" physical systems are losing information (energy, momentum, angular momentum and charge) towards infinity is well known. That's just thermodynamics at work. It does not change if we replace classical mechanics with quantum mechanics. We just end up with infinitely larger phase space (which many theorists ignore conveniently) but the basic upshot is the same: systems radiate and that radiation contains "the information loss". Take an ice cube. Leave it on the table for a couple of hours. It exchanges heat with the environment (that's the information loss mechanism) and what's left is a puddle. The shape of the puddle tells us nothing about the shape of the original ice cube. What theorists are trying to do here is basically just that: extract information about the black hole from the distribution of its Hawking radiation. In practice impossible. In theory, however, there is a formula (that one simply can not solve) that should be doing just that. There are actually two of these: the classical one that has one Hamiltonian phase space and a quantum mechanical one that has an infinite number of copies of that phase space in it. The two differ in their results. Surprise. Quantum mechanics IS NOT classical mechanics. Or better... it's STILL NOT the same, not even with gravity in the mix.

  2339. It is not in the past from the viewpoint of the ship. It is in the past from the viewpoint of Earth. In relativity the finite speed of light is simply a consistency criterion that assures that causality is guaranteed for ALL observers and not just for some. Of course you can always pick observers even in the FTL scenario that won't see a causality violation, but that's not the case for ALL observers. There will always be some who will see unphysical effects that simply do not happen in nature.

  2343. That is exactly what an MRI machine does. "The measurement problem" is a naive confusion by theorists with little to no physical intuition. Because of angular momentum conservation a spin up here means that somewhere something needs to have a spin down. The only question is "where that something is".
    1
  2344. You don't need complex numbers for any of these things. Matrices do just fine. Complex numbers are just a convenience for the case of two dimensional rotations. Quaternions are a convenience for three dimensions. After that it's all matrix algebras anyway. There is no point in trying to push the hypercomplex algebras any further. They have their limited uses and after that the classic algebraic approach is more or less dead.

At the last private company that I worked at everybody was responsible for their own workstation.

If your company doesn't work that way, then you need to go to a better company.

    1
  2370. @ Probability waves don't exist, either. There are no particles and neither do probabilities appear in quantum mechanics. These are all just horrible scientific misnomers that we have to get rid off. What does exist in reality are quanta of energy and histograms of their relative frequencies sorted by energy, momentum, angular momentum and charge and, if we want spatial resolution, by detector channel (which is a proxy for spatial volume/time slice). That's "real". Quantum mechanics allows us to estimate the frequencies in those histograms using abstract mathematical quantities that only exist on paper... like wave functions and projection operators. I don't know why any of this seems to be so hard to understand. If any of you had done a half day experimental physics lab with a gamma counter and an Excel spreadsheet to plot the results, then the not so fine line between "reality" and "abstract mathematical quantities used to describe reality" would be about as wide as the Amazon river near its estuary. :-)

    1
  2372. Because it is an automatic property of the theory. It follows directly from statistical independence of measurements. For systems for which this independence is not true (plenty of examples for that), the naive linear formalism can not be used and we need to use formulas for conditional probabilities, instead. A very famous example is the Mott problem and you will generally encounter the need for conditional probabilities whenever you are trying to calculate the quantum-classical transition realistically. All the derivations that use pure ensemble formulas are wrong by design.

It is an offspring of string theory that actually seems to make a physical prediction that is testable, a kind of gravitational background noise that deforms light waves... and that prediction is wrong by many orders of magnitude. There is skepticism about the derivation of that predication as well as some of the experiments/observations that have been performed in that direction, but either way it's obvious that either the string theory folks don't know what they are doing and/or nature doesn't give a frell about the whole thing. I suspect the latter.

  2459. I can't do math and if my life depended on it and I still have a PhD in physics. If you ask me about quantum mechanics I can explain it better to you than most theoretical physicists (even though I can't calculate a thing with it). That is not the problem. The problem is that hard sciences and engineering are very different from the simplistic ideas that people have about them in high school. I am quite good at EE in addition to experimental physics, but I would not have survived the sheer monotonicity of a EE university course. Being good at something in practice and actually being proficient at it at the university exam level are simply two pairs of boots and one is much, much heavier than the other. That liberal arts colleges let so many people pass is, by the way, just part of the business model. You can't tell a liberal arts student that he/she has absolutely no artistic talent and that they are wasting their time. If you did that, then almost nobody would graduate. It's an entirely different game in e.g. medicine (where it's important) and classical music (where nobody wants to hear you butcher Chopin for four years or more).

  2460. The actual problem you have with theoretical physics is that you are too lazy to learn about it. ;-)
    1
  2461.  @angelmujahid2233  Why does a fact suddenly become an ad hominem attack? How much time did you spend on learning theoretical physics? Among physicists eight years 24/7 is considered the theoretical minimum. An experienced theorist will have 20-30 years of full time experience or more. ;-)

  2462. Not much difference for a physicist. A measurement is just an observation that has also has useful estimates for measurement errors. To nature it's all the same.

  2463.  @artinweddings  Dude, why are you telling me that you have no clue about physics? I don't care. I am an experimental high energy physics PhD, by the way. We are doing a lot of things, but we aren't slamming baseballs together, kid. ;-)

  2465.  @artinweddings  Physics is not a matter of belief. It's a matter of knowing how nature behaves, which means that you have to spend time with nature. That's usually done in the physics lab and you haven't done that. I have. At CERN and a couple of US national laboratories. I have designed machines that have made trillions of quantum measurements. In none of them did nature behave the way you think it does. Call me again when you are past childish beliefs and you actually care about LEARNING. ;-)

  2472.  @vitulus_  You can find Everett's mistake in the second sentence of his thesis. He simply didn't understand quantum mechanics. Oh, wait, you never read it and you don't understand quantum mechanics, either. ;-) Where did you get the idea from that nature is deterministic in the first place? It's a trivial fact that anybody can tell you last week's lottery numbers but nobody (including Everett) can tell you next week's. That alone rules out that nature is deterministic. This is a kindergarten level science observation, so I have to ask: why did you stop paying attention in kindergarten? ;-)

  2473.  @vitulus_  The modern interpretation makes exactly the same mistake. Can you name it? I can. :-) Copenhagen doesn't contain that mistake. Copenhagen tells you exactly what happens in nature. All you have to do is to listen. ;-)

  2482. There can be no non-locality. Non-locality automatically violates relativity. The main ontological problem here is that wave functions are not even physical properties. Most people, many quantum mystics included, don't seem to realize that.
    1
  2483.  @Morberticus  Yes, what people call non-locality is non-separability of certain states. Non-locality simply doesn't exist, non-separability is an absolute necessity. One can't satisfy any of the conservation laws without it. It is only subtle for people who never got further than their first introductory quantum mechanics class into the subject. Everybody else will recognize this to be part of the trivial preliminaries to real physics.

  2484. There is no such thing as a measurement problem. There are only people who didn't read von Neumann's 1932 book, chapter five or six, if I remember correctly.

  2499. OOP doesn't make sense in Python. It's just a bolt-on for the diehards. It doesn't make sense in any dynamic language. It doesn't give memory footprint or performance advantages and it does not enforce types and interfaces, either, which means that code isn't safer against compile-time checkable bugs as it would be in strongly typed static languages. So that leaves only one function: documentation. Since you are unlikely to code large systems in Python (if you are, then you are an idiot to begin with), that kind of documentation isn't needed. :-)
    1
  2500.  @charg1nmalaz0r51  All of that can be encapsulated in libraries and has been in the past, even when people were still sacrificing to the gods of Fortran and Algol. We simply don't teach how that's done in a rational fashion much.... which is a pity. OOP is, on some level, just automated namespace management for dummies. Don't be a dummy. Think before you write. The problem with OOP is that it manages all these things in one particular way, which is often not useful for problems that require different techniques. What happens when you apply the wrong solution to a problem without thinking, however, is that you are making it worse. Enters the dragon of endless re-factoring.

  2504. They are Protestants. It doesn't seem like their beliefs are all that different from those of other Protestant denominations. There seems, at least to an external viewer, a closer relationship between beliefs and actual behavior than among the general Protestant (and Catholic) population, where beliefs and actual behavior usually diverge wildly.

  2505. Some numbers (the finite integers) can be implemented as cardinality of sets. Negative numbers can't. They can still be found in the differences between sets, which is a well defined concept (as a physical operation). You just described how it works. One set of apples has more members than the other. The one that has less can be assigned a differential cardinality relative to the other and that will be denoted by a negative number.

  2508. I recently went into the nearest public library. There was not a single physics textbook in the physics section. Honest to god, not one. I would have expected at the very least one or two college level textbooks about classical mechanics, electrodynamics, quantum mechanics and optics. I wasn't even hoping to see an atomic, nuclear physics or general relativity textbook... but there was NOTHING. All I could find were nonsensical things like Hawking's layman's books and stuff like it. Not even Weinberg's "The First Three Minutes" was there, even though that's at least a somewhat useful classic. Not even one copy of Heisenberg's "Physics and Philosophy" or Feynman's "QED" for historical reference (the content of both books is questionable from a modern point of view, but you as a librarian are neither required nor expected to judge that). This is NOT a problem with academia. In comparison, the physics section of the university library closest to me has something like 15,000 physics textbooks and a hundred journals (with many more online), if I remember correctly. So, if you want to talk about a real crisis here, it's a crisis of the public library system.

  2519.  @Outspoken.Humanist  I am a Catholic. I can tell you that Christianity is not following Yahweh. We aren't even living by his law. I eat a lot of pork, for instance, and shellfish. Yahweh doesn't like that, the Christian holy spirit, whatever it might be, doesn't give a frell. Not even close. Would you like a good serving of Saints with that?
    1
  2520.  @StonesSticksBones  God, son of god, holy spirit, Maria, goblet full of saints.... that's not what monotheism looks like. And let's not forget the devil... just for good measure.
    1
  2521.  @StonesSticksBones  I did. No priest could ever explain to me what the holy spirit is and what it's good for. It is, of course, not good for anything. Somebody put a third bullet point on an ancient power point that only had two. That's all that happened. Theologically there is no need for either the son or the holy spirit, which explains why Judaism is still around. The Jewish folks never bought into this bullshit.
    1
  2522.  @Outspoken.Humanist  Catholicism is not quite as bad as Mormons in the adhesion department. They can even convert you after death, it seems. Catholics do not believe in Yahweh, though. The Catholic god is a completely new entity. Technically they don't need any of the OT, really. Christians, in general, only retain it because of a few references that are supposedly predicting the coming Messiah, which is highly dubious. :-)

  2525.  @StonesSticksBones  I am calling myself a Catholic because I was sprinkled with Catholic miracle water as a baby.

Now please excuse me, as a Catholic I am allowed to cook a goat in his mother's milk, which is what I am going to do, Yahweh and his law be damned. :-)

  2526.  @Outspoken.Humanist  Christians do worship more than three gods. I don't know why people don't get that. Have you ever been in a Catholic Church with a lineup of saints on each side? Every atheist can see that very clearly. Why do we even have to discuss that triviality?

  2535.  @barneyhall2753  The same as we do. Nature doesn't change just because somebody else is looking at it. If somebody wants a balmy place in the solar system, Mercury would be it. Plenty of solar energy and heavy elements through the roof. The lower surface gravity makes spaceflight way, way easier. Anybody who wants water will go to the icy moons of Jupiter or Saturn or directly to Pluto. 11km/s escape velocity is a giant pain in the bum, at any level of technological development. Super-earths with two or three times the escape velocity are far worse, still, but are likely to have plenty of water and dense atmospheres for life... while being outright hostile to a space fairing civilization. Earth is close to the limits for spaceflight. Any more mass and getting in and out of the gravity well is getting enormously expensive. So why would AGIs go through all that pain when they can live better almost anywhere else?

  2550.  @RandoCommando24  Complexity is not the sign of great art. Art is entertainment. Of course War and Peace was good entertainment for its time. I would never argue with that. So are Beethoven's Sonatas for people who didn't have radio and tv but who had access to a piano. That entertainment, however, can quickly turn to torture if you force it on people who are used to different forms of entertainment and who don't suffer from boredom. If something is no fun any longer, then that's just a fact of life. So, no, art is not timeless. It lives in and dies with its own time. If you don't believe me... then I have a museum full of religious paintings in Milan for you. It's a large three or four floor building with nothing else than picture of Madonna, little Jesus and Jesus on and off the cross for you. Go there and let's see if you really find that enjoyable. They are all medieval masterpieces. No doubt about that. I have seen it and I will rather watch Madonna's "Cherish" video a hundred times in a row than see it again. The mermaids are hilarious. ;-)

  2575.  @ylvaseason  Most mathematicians are rather normal people, they are just very specialized. I am a physicist but out of fun I went to a mathematical colloquium once. There were half a dozen mathematicians and half a dozen students there (in the physics colloquium at my university it was five to ten times as many). The speaker came from an entire different subfield of math then the people in the audience. He put up the basic definitions of his field on the first slide or two, then he began talking about his current work. After about ten minutes of total silence of the audience one of the professors raised his hand and asked "Would you mind putting the first slide up, again. I think you lost all of us at the definitions.". Big laughs because it was true. Absolutely nobody could follow what the speaker was talking about. I had a similar experience in a math seminar about quantum groups. After about an hour everybody in the seminar agreed that they had absolutely no idea what this stuff was about, not even the guy who was giving the seminar. I still don't know what a quantum group is... some 30 years later. ;-)

  2581.  @richardchapman1592  Particles are simply a misnomer. A precise quantum measurement takes an infinite amount of time, as you can easily see from the time-energy uncertainty. That alone tells you that the measurement process has to involve the entire field volume and not just a tiny "particle" volume.
    1
  2582.  @TimoBlacks  Wow, you just said something intelligent and then you have follow it up right away with total garbage. When did we ever teach you something about "points of energy"? Did you come up with that bullshit on your own? :-) A quantum of energy IS field energy that gets transferred to the measurement system. No energy transfer, no measurement. The quantum only "exists" as a consequence of the measurement process and after that process has happened that energy is lost to the field.

  2586.  @richardchapman1592  An AI can only tell you the bullshit that it has been trained on. Since quantum mechanics is a wonderful theory with the most awful (and outright deceptive) language layer and AI works exclusively at the language level, it's a case where AI can not but get it all wrong. Your problem is also that you are taking all of these terms literally and they are literally all wrong. How "quantum mechanics" talk about nature is not how nature actually behaves. We have had a century of poor teaching habits and this nonsense has entrenched itself so deep in the physics community that it's hard to exorcize. I have met only a couple of excellent theorists in my life who actually understand this educational problem. Most are still in denial that we will have to rewrite the textbooks.
    1
  2587.  @richardchapman1592  There are no particles. What would "observing an infinitely small speck" mean, anyway? That's just nonsense. So what are we observing? We are observing energy changing from one system to another. That's why it is called "quantum mechanics" and not "particle mechanics". Quanta are small amounts of energy. Energy is the ability of a system to perform work on another system. It's a system property. We teach this in high school. We never teach that energy has size. We never teach that energy has position. We never teach that energy moves. Energy can flow from one system to another and it can change from one form to another (e.g. kinetic to potential). Forget about "particles" as fast as you can. It's a completely useless concept that causes nothing but problems and the math of the theory says absolutely nothing about it. The math starts with energy, momentum, angular momentum and charges and ends with an estimation of event frequencies. At no point can you tickle "particles" out of it. And what about waves? Waves are a perfectly classical phenomenon. Water has waves. Air has waves. Do water and air have to be quantized to explain waves? No, of course not. Waves are also representations of the Poincare group. The only requirement to get waves are a) linearity (check) and b) translation symmetry (check). All of this is high school level physics, by the way. We are teaching all of it correctly... right until people hit QM 101 and then intellectual hell breaks lose because the confusion that the founders felt is still lingering around in language like "particles"... for absolutely no reason. In reality all of this was perfectly understood by 1932, latest.

  2588.  @richardchapman1592  Nobody has ever observed the molecules in water waves as far as I know and it's not necessary to understand the microscopic structure of water to model these waves mathematically. We are teaching in high school that waves are phenomena that obey a simple functional equation like f(x) = f(x+a), where a is the period of the wave. Where in the world do you see water molecules in that? Where does Planck's constant show up? :-)

  2589.  @richardchapman1592  Brownian motion is not waves. There is no periodicity at that level. Neither is there exact periodicity at the quantum level. In order to get "smooth" wave functions we have to average out over an infinite number of systems in the quantum mechanical ensemble. That's an abstraction. It doesn't exist in nature. Once we do this abstract averaging, however, we are at risk to lose effects that are distinct to quantum mechanics (like angular momentum quantization). You won't see any of that in mean field theory experiments like that infamous double slit. You are merely reproducing the translation symmetry of spacetime that you can just as well test with water waves. If you want to know "what is ultimately behind ALL of this", then I can give you a simple answer: the relativity principle. One can derive absolutely all of known physics from an insight that Galileo formulated in 1630 in a short paragraph known as "Galileo's ship". Quantum mechanics follows just as easily from it as classical waves... but it doesn't follow the same way and that is one of those things they are not telling you in school. It's not hard to figure out, but until you do all of this will look utterly confusing.

  2590. ​@richardchapman1592 There are no particles. There are only students who aren't paying attention in high school when we explain to them that quanta are small amounts of energy.

  2642. The photon IS the energy that we are absorbing in the measurement system. One can not absorb half a photon. This is forbidden by angular momentum quantization. The explanation with Gaussians for the double slit is incorrect, even in the classical case. A single slit has sinc (sin(x)/x) functions in the Frauenhofer approximation as scattering amplitudes. That function still has minima, they are just not as easily visible as those of the double slit. The cause for the sharp minima has nothing to do with physics. It's a feature of the Fourier transformation. As a rule of thumb, if the original function has "sharp edges", then the Fourier transform can contain these first order zeros. The details when these zeros are occurring are complicated, though, if I am not mistaken. Anyway, if you want a nice Gaussian diffraction pattern, then you have to have a smooth, Gaussian slit response.

  2643.  @jamesbra4410  There is no such thing as a wave function collapse. That's a word that you won't even find in well written quantum mechanics textbooks like Sakurai. It's online. Go look it up and do a search in the pdf. Energy also doesn't have a path. It never had a path. It never even had a location. We never taught you that nonsense in high school. Energy is the ability of a system to perform work on another system. It's a SYSTEM property. A system is an arbitrary partition of nature by the physicist. Depending on how YOU chose your system partitions you will find the energy in there... with a probability that depends on YOUR choices. Dude, all of this is easily understandable by students who are actually listening in high school... which none of you did. ;-)

  2648.  @FizzleFX  Not sure about that, either. Schroedinger had a very weird style. Of the five papers that lead up to the Schroedinger equation only the SE paper is even borderline intelligible for my taste. It is clear what he was trying to achieve with Schroedinger's cat, of course, but he picked a really poor example and he failed to analyze it properly. It's a little bit like Einstein and EPR and the later Heisenberg. They all came so close to understanding quantum mechanics properly and then something in their minds reverted back to semi-classical thinking. Very strange, indeed. Hindsight is 20-20, of course. For us it's much easier to stand on the shoulders of these giants than it was for them to give us this view.

Most people have simply not caught up with the state of the art from 90 years ago.

  2670.  @OhAncientOne  Let me put it this way... nothing is "supposed to be this way or another" in science. Science is no a p***ng match with nature. We observe, we describe.

It's not an actual statement about nature. ;-)

  2671. No, quanta, which are energy, don't "exist" in spacetime. They exist in what physicists might call "system space", but it's not really a space. There is a bit of a complication here in that quantum theory relies on energy being conserved exactly, while that is not the case in general relativity because the universe is not time-translation invariant. The violation is subtle, though. I don't know of a case that could be made how it would significantly change the structure of QM.

That was plenty of time to move away from Gaza and to start news lives in countries of their choice where they could have given their children an education and plenty of economic opportunities. After three or now almost four generations they could be living healthy, happy and often prosperous lives in their host countries. Instead they chose endless conflict, often using their women and children as shields in a war that they can't win. Morally every Palestinian who still lives in Gaza is complete bankrupt. And now they are also economically bankrupt without having achieved anything. What was all of this good for?

Every actor in it is acting rationally (the Pharisees are trying to protect their people from the Romans and the Romans are their usual cruel selves), expect for the fool who draws the short stick, but then he is a crazy apocalyptic preacher, so he is acting like you would expect him to. The persecution of Jesus and the inevitable conclusion are probably the most realistic parts of the gospels. It's easy to tell when they are lying (about the miracles and the resurrection), but there seems very little lying going on about the end of his life. He was a liability for the people of Jerusalem and the real-politicians on both sides decided that getting rid of the man was the thing to do. It was the correct decision, by the way, because it prevented a genocide for another 35 years, which only came in 70AD.

  2702.  @clayfoster8234  I don't have to because it doesn't matter. All I am saying is that the story checks out, just not the way it is being sold to to Christians. The good boys in the story are the guys who got this rebellious preacher buried because he was about to burn the place down.
    1
  2703.  @benjalucian1515  You are looking at all the wrong details. All of that is made up or based on Chinese whispers. The people who wrote the gospels weren't there when it happened. The important part of the story is that the Jewish people had been living under occupation for six centuries, similar to the Palestinians today. They were losing hope and some of them were, literally, losing it. There would have been the equivalent of an Intifada movement which was waiting for the one guy to shout "Now!". The temple, which was the one somewhat unifying political force among the Jewish people knew this. The Romans knew this. The Romans had told the temple priests what would happen once that guy made that noise and the temple priests understood that the Romans didn't just talk bloodbath. They meant bloodbath. And then Jesus shows up and keeps saying "I am not saying it's now... I am not saying it's now... I am not saying I am the guy.... but I am the guy.". What would you have done to save the lives of your family if you had been in the temple? Let the guy walk around with his "I am not saying it's now..." story or feed him to the Romans? Exactly. They fed him to the Romans. It bought them 35 years before they eventually ran out of time because some other guys were shouting "Now!". You just have to get past all the irrelevant details. Nobody cares what the colors of the lamp posts on Jerusalem's High Street were and if any of the Evangelists got it right. What matters is that there was a massacre in Jerusalem in 70AD and THAT is the true background of the Jesus story.

  2704.  @benjalucian1515  What is an assumption? That the temple had to make arrangements with the Romans? Of course they had to. Paid good money for what little freedoms they could buy, too.

Still think that the right lie whispered into the ears of dumb people can't cause harm? I don't know where you are getting that weird timeline from. The Jewish people hadn't been free for like 600 years at the time of Jesus. All of modern Judaism was basically created in captivity and under the authority of or while in constant conflict with external forces. It's a slave religion of a small people who were hoping for salvation. Maybe you should read the OT, again, this time with an eye on politics. The book is choke full of it.

  2713. Everybody knew this. But what, exactly, do you expect? If teacher performance is not measured by relative student improvement, which is the best any teacher can ever do, but by a stupidly low absolute standard that the average kid from a poor household will still fail, then the only response teachers have left is to lower standards for everybody and to teach useless but dead simple algorithms to every kid. That brings the gifted student from a rich household to his knees, but raises the poor student just enough so that the teachers in poor school districts continue to be employed. That's a political problem, not an educational one.

  2720. The US has been and is still supporting Ukraine with its most important assets: space intelligence. Why do you think did the Ukrainians shoot down the Russian radar planes? Because Russia is short on space intelligence. At most they are getting it from China, right now. I wouldn't be surprised that one of Biden's last acts will be to covertly shut down Chinese spy satellites before he leaves office. We have the means. We have been doing it to the Russians for decades. It was an open secret in the Russian aerospace community that Russia has been blind for a long time. That wasn't just because of blunders in their space programs. We never left the cold war... you could see it in Putin's increasing frustration with the West. His country was under attack, he just couldn't admit that they were losing the cold war. His childish reaction was to start a hot war, which he is losing right now. If the Chinese get too involved we will do the same to them that we did to Russia and they won't even be able to admit it that we are behind their failing infrastructure.

  2725. Good question. I don't know, but when it comes to Feynman I would be careful. He does, as Maudlin say, give a lot of beautiful intuitive explanations, but it turns out that many of them are wrong and while they seem to lead to short term insight, they are doing an enormous amount of damage in the long term because they are "just not so". Maudlin's own explanation of the twin paradox is wrong, by the way. It's not the motion of the clocks that changes the clocks. Clocks never change. Clocks are simply ways to measure causality between different physical systems. If you want to understand the twin paradox, then you have to go back to the actual observations. What really happens if a clock is moving relative to us? It gets redshifted when it moves away and blueshifted when it moves towards us. It also gets delayed when it is at a distance from us. These are the actual physical effects that are related to relative motion and displacement. So when the traveling twin starts his journey, the clock of the stationary twin gets redshifted for him (and the traveler's clock gets redshifted by the exact same amount for the stationary observer). The "magic" happens when the traveler turns around: he experiences the change in the stationary observer's clock right away: it turns from red to blue. For the stationary observer, however, that event only happens a long time after the traveler has turned around because he keeps receiving the traveler's redshifted signals even while the traveler is already on his way back. That's caused by the inevitable signal delay between distant systems. We are always seeing the past of a system that isn't where we are. We can never see its "present", i.e. its actual physical state. This means we are seeing the redshifted past of the traveler longer than we are seeing his blueshifted past and that is the self-consistency reason why the traveler has aged less than we have. One could argue that the concept of "proper time" describes this phenomenon in another way, but there is a problem with that: it requires "god mode", i.e. in order for us to know the "current proper time" of a system in motion we would need to know where it is right now... but in reality we only know where it was a considerable time ago. In that sense Einstein's formulation of special relativity breaks with its very own principles that we should only care about what is and not what we imagine should be.
    1
  2726.  @alexanderkohler6439  You can't see those "fundamental metric properties". They are only in your mind. The only thing that you can see are Doppler effect and signal delay. That's what I mean by "god mode": even the conventional formulation of special relativity only "works" if you assume that, like god, you know everything, everywhere, all at once. In reality you don't. That's the reason why special relativity can't do acceleration. Acceleration does not get signaled to a remote observer right away. It is subject to signal delay. So, yes, you have a "fundamental explanation", but to get there you have to break reality and replace it with a convenient fantasy... one that only works for a single special case: for two systems that have been in constant relative motion against each other for eternity. It's not wrong, of course, but it suggests a level of knowledge about the world that the actual relativistic observer does not have. To pretend that we can know the eigentime of a system in arbitrary motion is simply not physical.

  2727.  @alexanderkohler6439  I can't know most of the physics that will change my future 1 second from now. I would suggest that you take a good look at a spacetime diagram.

  2728. Classical? Not particularly useful because they are using too much energy compared to electronic machines and light doesn't scale all that well. The wavelength of visible light is already much larger than the feature size of silicon. For quantum computers... don't know. It might become a viable technology with the never integrated optics and better optical materials. With macroscopic lenses and mirrors... probably not.
    1
  2729. It's the other way around. All of mathematics was originally an abstraction of physical observations. We didn't "invent" numbers. They dropped on us because classical objects can form collections that behave like sets. Set theory is literally an abstract extension of "fruits in baskets". One can say the same thing about the real and complex numbers, groups, Riemannian manifolds etc.. There is, of course, a "backreaction". Some deeper properties like the topological properties have non-trivial and not easily accessible consequences for physics, which wasn't understood until relatively lately (as in the last fifty years, roughly) and we are still working very hard on exploring these connections.

  2730.  @worldnotworld  I didn't say that these things are not real. What I am saying is that all these ideas came from real things and real world problems. Mathematics, at the core, is physics that has been liberated of its experimental and observational basis. We can discuss whether things like the axiom of choice have any relevance to practical applications of set theory in science (I don't believe so), but these are, IMHO, fringe problems, even for most mathematicians. What will hit the mathematicians really hard in a short amount of time (less than a century) is the fact that physicists have already liberated themselves from the idea of objects with the advent of quantum theory. Sets are simply not what underlies nature. Implementations of sets in form of classical objects in classical baskets are merely an emergent property of nature. There has, as far as I can tell, not been any serious work in mathematics on the idea that maybe one should start math not with sets and formal logic but with a generalized version of quantum mechanics. Quantum math (which is NOT the same as the math of quantum mechanics but much, much more general) simply does not exist, yet, but eventually it will.

  2735. The adult industry is not quite as innocent as you want to portray it, either. The real problem is this: our laws cover professionally produced pornography. As long as producers verify the age of the actors, have them sign wavers and store those with an attorney, almost anything goes. If a husband and wife make love and film themselves, posting it becomes a legal liability because they don't have the required documents and legal representation. It's a liability for the couple, it's a liability for the hosting sites, which are not allowing "amateur videos" that reflect human sexuality better than any of the produced stuff because they can't make credit card transactions if they get sued for breach of privacy. So now only "verified" material can be hosted. But verified material is expensive to produce, so it has to make money, hence producers feel a need to film the sexual equivalent of circus acts.

  2736. Nothing ever collapses. That is just a very unfortunate choice of words that is stuck in the heads of people who don't understand physics. We are explaining this correctly in high school when we teach the photoelectric effect. There students learn that "photons are small amounts of energy". Energy can only be used once. If we observe a photon at one of the slits, than that energy can not be observed a second time at the screen. There is no need to use language like "collapse". It's simply absorption. Light hits a detector, gets absorbed and the energy gets converted in heat.

  2744.  @marcozec5019  One has to understand measurement as a real, hands on, expensive lab hardware kind of process. It is not some "esoterical, mathematical, philosophical" abstract. A typical quantum mechanical measurement apparatus is like a spectrometer, which consists of an aperture/grating system that separates different wavelengths of light, followed by a detector, which could be a photodiode, a CCD camera, a photomultiplier tube or just the unaided human eye. It turns out that we can build many different kinds of spectrometers of this kind, that select different properties of the light. The most simple grating is a single slit, which detects if light is coming through one particular spatial region. The next kind is a lens followed by a single slit, which detects if light is coming from a certain direction. The first kind of measurement is a position measurement, the lens makes it a momentum measurement. With an input slit and a fine physical grating we arrive at a true spectrometer that measures the energy distribution in the incoming light. We can add a "temporal aperture" and then get time dependent distributions as well. What never changes is the actual detector, which always removes energy from the electromagnetic field. What the math of the theory describes (in an abstract way) is the particular physical effect of our physical apertures/lenses/gratings etc.. This is almost never mentioned in theory textbooks. For that you have to study experimental physics textbooks which explain "how" a particular measurement can be done with actual physical means. There is, unfortunately, no trivial correspondence between experimental hardware and the operator calculus that we can find in theory books. There simply can't be because there are no "ideal" experiments. A quantum mechanical "measurement operator" can, at most, be crudely approximated with actual lab hardware and there is a lot of art and hard work to that experimental process. Most of the "fundamental problems" in quantum mechanics stem from the different kinds of approximations that we have to make to get from real hardware to the operator calculus. They exist in the theory but they don't exist in reality because the limits of the theory that cause the perceived problems are being made obsolete by the actual physical processes that are happening in an actual measurement. One can learn some fundamental insight from that, as well, but they are usually lost in the theoretical literature which suffers a little bit from naval gazing. If all you do all day long is to look at the structure of the ideal theory, all you will ever find are the problems with the theory, whether they are actually present in reality or not. Most of them are not.

  2778. QFT is local in the sense that the Hamiltonian is local, which can be expressed as commutation between the Hamiltonian and all other operators at different spacetime locations (I am not a theorist, so don't nail me to the precise conditions). It is strongly "non-local" in the sense that multi-particle states are always symmetric or anti-symmetric, which leads to the entanglement of states due to these symmetries. I have heard opinions that this should better be called something else, like "inseparable" and I would agree with that since non-locality in classical physics was defined differently. Having said this, the language of QFT is (for historical reasons) a big mess, anyway. There are, most notably, no particles in QFT, even though textbooks and physicists call quanta particles all the time, which is one of the worst misnomers of all times in physics. So, essentially, you just have to get used to the language idiosyncrasies and do mental substitutions for poorly chosen terms all the time. So what shall we call this, then? QFT is a "local but inseparable theory", maybe?

  2813. The decay of a nucleus is described in quantum mechanics by a superposition of states. One state is the intact nucleus times the empty space state. The other states are the decayed nucleus and the ejected photon/electron/alpha state. The latter is a continuum of free particle states that fill the entire volume around the nucleus. If we can make a completely closed, perfectly reflective box around the nucleus (like imagined by Schroedinger's cat), then the decay is never complete, i.e. there is a finite (but small) probability to find the nucleus in its non-decayed state at all times, even long after many decay time constants have elapsed. If we make this shell very close to the nucleus, then it will basically never decay. How could it? The decay energy has nowhere to go. The effective binding energy of the nucleus has been altered by the reflective potential of the box and it is no longer unstable.

He constantly kept trying to classicize the world, even though that's a pointless exercise (a classical world can not contain any matter) .

  2822. Some ideas in Rust are good, but some seem total garbage. State handling in types is one of the stranger choices that do not compute with me. We have to be careful with state because state blows up the test space. It doesn't matter if we leave exponentially growing state to the compiler or not... it's still not testable. The underlying assumption behind this feature seems "safe by design". No such thing exists.

  2826.  @ИльяАнфимов-ъ7н  It means that Dirac had the wrong intuition about quantum mechanics, or that he was using problematic language, at the very least. The individual system does not have a state before measured, which means it can't "jump into it" as consequence of the measurement. All the quantities in your math are ensemble quantities. They aren't making ANY statement about individual systems. It is not the math that is wrong here, but the interpretation of the math. We know what quantum mechanics is. It is a geometric partition of unity that happens to satisfy relativity. The "unit" in this partition is the unitary totality of all events in the quantum mechanical ensemble. That is how the theory was constructed from day one. It differs in nothing from probability theory in that regard.

  2828. There is no right to get what you claim you need. Investment firms are typically not buying single family homes. It's not a business model they can make money on. Neither can you typically convert private homes into commercial real estate in the US. The local zoning laws usually don't permit that. That's part of the problem. Single family zoned areas can not be converted into multi-level condos that provide more living space for people. We have plenty of suburbs with a density of half a dozen people per acre or less. That's a total waste of what is essentially urban area.

  2838. Salam is a working theorist for all I can tell. He has recent publications (with others and first author) on arxiv. Sabine used to be one but she worked herself out of the field by publishing meaningless drivel papers. There is no there, there, for all I can tell. Ekeberg is just an author. No trail of papers on arxiv and I don't care to look elsewhere. It's not worth my time. There is a consensus in the community: we need data. What nobody can tell you is where that data is supposed to come from. We lack workable accelerator technology options that would reduce the price/TeV by at least one or two orders of magnitude and we can't solve the problem by throwing a trillion dollars at it using current technology. This isn't rocket science, but it's very similar to rocket science: the field is mature. Elon Musk can build a rocket that is a tad larger and more capable than the Saturn V was, but not much more than that. Nobody will be building a direct to orbit fusion drive torch ship that can travel to Jupiter in two weeks anytime soon, but that fantasy is exactly the equivalent of the kind of accelerator that high energy physics might need to take the next (serious) step. Should we shut the field down because of that? Of course not. That's just Karen's, forgive me, Sabine's wet dream.

  2852.  @gsmollin2  Why would quantum mechanics require that? MWI is simply the proof that Everett didn't understand quantum mechanics, either. So that makes three of you now: Einstein, Everett and now you. ;-) Of course the strange state of public understanding of quantum mechanics enrages me. We are teaching in high school that "quanta are small amounts of energy", which is basically all you need to know to derive the theory from, but nobody seems to be paying any attention. Are these six words a joke to you guys? :-)
    1
  2853.  @gsmollin2  Except that Einstein didn't believe his own explanation. Read his paper and you will find a sentence in there in which he immediately identifies those quanta of energy with Newtonian corpuscles that have position and path. That sentence is 100% wrong. It is also 100% unmotivated by the actual experimental evidence. Most importantly it is unnecessary. Nowhere does the photoelectric effect require that photons have position and path properties. It's complete intellectual nonsense but Einstein never managed to get rid of this unnecessary assumption in his own mental models as far as I can tell. Every time he talks about quanta he refers to them as if they were Newtonian corpuscles. To this day most people can't let go of that nonsense. MWI doesn't follow from Copenhagen. It's a complete misunderstanding of Copenhagen. Copenhagen simply tells you the facts on the ground: quantum mechanics is a theory of independent ensembles (because individual experimental outcomes are not predictable) and it requires two of those: the ensemble of the free quantum system and the ensemble of the quantum system plus the measurement system because the actual physically measured outcomes depend on the spectral absorption function of the measurement system. Everett didn't understand either of those statements. Einstein may have come close to understanding the ensemble character, but I kind of doubt he ever understood where that came from (hint: it comes from special relativity!). End of story. ;-)

  2881. Wheeler had a few serious misconceptions about quantum mechanics. He was a great relativist, though, except when it came to understanding that quantum mechanics is a direct consequence of relativity. He had that in common with Einstein, it seems. It's a bit of a professional blindness. Having said that, observationally "the past" is all of that which has left a permanent record. More generally, "reality" is that which leaves a permanent record. This is a very important principle that one has to learn to embrace, especially when dealing with quantum mechanics.

  2882. I don't know what the "decay rate of Earth's magnetic field" is supposed to be. The field doesn't decay. It changes polarity and loses most of its dipole moment more or less periodically. That has nothing to do with radioactive decay. We are, by the way, NOT measuring the decay rate of long lived radioactive isotopes in a short amount of time. We are measuring the ratio between the number of observed decays vs. the total number of nuclei. If the decay rates were significantly non-constant, then the isotope ratios in old samples would be wrong, but they aren't. The world is consistent with constant decay rates.

  2914. For one thing... nobody has ever seen either a particle or a pilot wave. Physics is not religion. It's not in the business of inventing invisible, unknowable entities. All physics has to do is to describe what can be observed, preferably with as little effort as possible. Standard quantum mechanics does just that. At a somewhat deeper level it turns out that the physical vacuum is not made of single-particle states. Quite the contrary. It is not made of particles at all, but of a non-trivial number of quantum fields that interact strongly with each other. As "elegant" as pilot waves may look for the trivial case, trying to describe actual high energy interactions with them would be a horrible mess.

  2961.  @augustinemmuogbana3382  Absence of observation means that science can't say anything definitive about whatever is absent. Science is the description of what can and has been observed. That doesn't mean we can't make predictions of what should be observable to tailor our next experimental or observational hardware or strategy to it. Of course we can and we do. That's called hypothesis building and we do it all the time. There is no such thing as a theoretical observation. An observation is always a physical observation. There are theoretical predictions. Theory doesn't predict virtual particles in any meaningful form. It doesn't even predict real particles. Quite the contrary. Theory DESCRIBES real quanta, which are IRREVERSIBLE energy measurements at the field/external system boundary. It does not even predict quanta inside the field because there are no irreversible processes inside the field and there are no such boundaries, either.
    1
  2962.  @augustinemmuogbana3382  That's the definition of "observation" in science. It always refers to a physical event. Like I said, we can use hypotheses to predict phenomena that should be observable according to the hypotheses. Unless they are being actually observed, however, we can't assign "reality" to them. I can, for instance, calculate the exponential function of the number of hydrogen atoms in the universe. Does this mean that there is a physical observation that corresponds to this very large number? No. There is, as far as I can tell, no natural phenomenon that counts hydrogen atoms and then somehow implements their exponential function. Hence I will never claim that exp(n_Hydrogen) is a physical phenomenon. In the same way I can't claim that virtual particles are a physical phenomenon. They are an intermediate result in a calculation procedure that can, with enormous difficulty, be used to make SOME predictions about quantum fields. We can't even claim that it makes only correct predictions. The vacuum ground state energy prediction, for instance, is wrong by many orders of magnitude, which proves that something is fundamentally wrong with the calculation to begin with.

The physicist is simplifying life by realizing that one does not have to recalculate everything from scratch every time because some systems are sufficiently similar that one can treat them once and then reuse the results. That does not mean that we can't differentiate the actual physical systems. Of course we can. It makes a hell of a difference whether you get crushed by a giant pendulum or electrocuted by a resonant LC circuit. ;-)

  3021.  @NicholasLatipi  The underlying theory can be tested just fine. There is no requirement in science that every prediction of a theory has to be testable. Classical mechanics predicts the Poincare recurrence theorem. It's untestable. Does that invalidate classical mechanics as the right tool to fly to Mars with?
    1
  3022.  @NicholasLatipi  Nobody is trying to test a theory of quantum gravity here. We are simply asking the question which properties ALL viable theories of quantum gravity have to have in common. You can compare that to the Planck radiation phase of quantum mechanics. People had no clue in 1900 that they would eventually end up with U(1)xSU(2)xSU(3), but the Planck curve is still perfectly valid.
    1
  3023.  @NicholasLatipi  Youi can't know if something testable will jump out of the equations until you solve them. I am not sure what you are suggesting here? Arbitrary barriers what scientists are and are not allowed to think about? I am completely agreeing with you that the likelihood of testability remains low for ALL versions of quantum gravity. There might be tabletop experiments that can identify individual gravitons similar to how the Millikan experiment identified individual electrons... but Millikan didn't tell us anything about the electron-proton scattering cross section at 17.9GeV... so there. Testability is NOT the end of all means. It's just a tiny fraction of what physicists do. Beyond testability we are still required to think about both high level structural question of models and theories AND we need much more detailed experiments that go beyond yes/no answers. As critical as I am about this kind of "not even false" work myself, it has to be done by someone.

In other words, unless you can get tens or even hundreds of MW of waste heat from somewhere it's very inefficient. Since the storage and retrieval are intermittent, it's also not a good use of the waste heat source, unless you are using it to increase the thermodynamic efficiency of a peaker plant. That, of course, is not an actual storage solution. This is more of a technology looking for an application than an actual solution strategy.

She says what everybody knows: high energy physics is in a desert and cosmology keeps surprising us. Neither can be helped and we should call ourselves lucky that we haven't hit a desert in both areas, otherwise we would have a real crisis in physics. As is, however, we are not in the desert. We are having some of the best, most interesting times, ever. Well, maybe not if you are a high energy physicist, like she is. She made the wrong career choice. That's all.
    1
  3041.  @jefferyzielke7665  You would be boring her if you tried asking her about the stuff she does for a living. That was my point. I don't study quantum gravity. I used to do experimental physics, which means I can differentiate between where the theorists would like us to be and where we really are. We are nowhere close to the parameter ranges that they are talking about, please trust me on that. It's like a snail talking about flying to Pluto squared... that's roughly the size of the parametric desert between current experiments and quantum gravity. Baring a technological miracle that gap will simply not close in anybody's lifetime, probably not even in the entire 21st century. I wouldn't suggest any career for Dr. Hossenfelder. She has made her choices. If you are a young physicists in your first couple semesters in university, right now, I would suggest that you stay far away from high energy physics, especially anything that uses an accelerator facility. It's not that there aren't interesting detail problems there, but the next big breakthroughs won't be happening for decades, well outside your likely career horizon. Astronomy, on the other hand, is going through a technological revolution, right now. There will be amazing new instruments for fifty years to come (especially space based, long baseline interferometers). The amount of data that's in the sky is absolutely astonishing and it's ripe for the taking. That's the much safer bet. Having said that, most physicists end up in other fields, anyway. Solid state physics and material sciences always offer solid employment opportunities in industry, if that is what somebody is interested in. Positions in astronomy are rare and hard to get and that won't change... so unless you are top of your field... tough luck.

  3060.  @wdavid3116  Refactoring doesn't make poor code better. It's a completely algorithmic operation at the lowest level of code comprehension. All it does is to untangle poor architectural choices that were made without an understanding of actual dependencies. The reason why it's needed in OOP is the OOP workflow itself, which requires the architect to have god-like foresight because he is tasked to create ultra-strong dependencies through inheritance. And because OOP boxes the coders in very strongly very early on, the team ends up in all the wrong boxes. The only way out is frequent refactoring. For sufficiently large systems refactoring necessarily breaks more than it fixes in addition. That's the problem with strongly coupled systems. Good architecture avoids strong coupling.

  3074. @ Yes, that's my point. The popular explanations are all wrong. As soon as you have a probability, you need to have an ensemble, i.e. an infinite repetition of the same experiment. What would "a path" mean in an infinite repetition of these experiments??? A path is a classical quantity that describes the motion of ONE classical body. There is, of course, a way to get to paths in quantum mechanics, but it is NOT given by the standard formalism. You can read e.g. Mott's 1929 paper about the wave mechanics of alpha ray tracks. He derives in there how classical paths follow from repeated weak measurements on the system through an application of conditional probabilities. Those simply don't exist in the standard formalism.

  3084.  @susanperry9311  Eight of my relatives had omicron a couple months ago (that was the second time they got COVID-19). They reported loss of taste, cough, difficulty breathing, fever and malaise that lasted up to two weeks. All of them tested positive for COVID-19. Thanks for the reassurances, but I got all the data I need. The general assessment in my family is that COVID-19 is far worse than the flu. The fist time they got it some family members said it was the worst they had ever felt in their lives. One couple had it three times now and one person has long COVID-19 on top. Thankfully we didn't have any fatalities, yet, but I won't count on it for the future.
    1
  3085.  @susanperry9311  First time they had it was wildtype or pre-alpha or whatever you want to call it. The second time was already in the omicron wave, but you are correct, it may have been delta. The couple that had it three times had a wildtype and most likely a delta... so that kind of makes the third infection likely an omicron variant. Be that as it may, none of them ever said that it was "light". I only know one person with a light infection: a doctor who got it at work. The other people I know never had it... but then, they are fully vaccinated and boosted. The "sick" group in my family consists of antivaxxers and the couple that had it three times only had access to sinovac. They may as well have been given saline, IMHO. The other obvious division in my family is socioeconomics: everybody who got COVID was among the less affluent family members without higher education. Those who didn't were more affluent and better educated, i.e. they took far better care of themselves with masking and social distancing.
    1
  3086.  @susanperry9311  In my family bad choices all boil down to poor education. Don't get me wrong, these are awfully nice people. I like them. They are not malicious or anything. They simply don't have a working bullshit meter and they have been told all kinds of nonsense about vaccination on the internet. Their go-to phrase about COVID was "We are in god's hands now.", to which the remainder of the family responded with "And god was giving with both hands!" when they got infected for the second time. The simple fact is that one can't talk sense into people who don't have it already.

  3089. The age difference between the two twins is caused by Doppler Effect and signal delay. Most explanation you keep hearing are simply wrong.
    1
  3090.  @alexanderkohler6439  My point is that the actual physical effects that are observable and "physically real" (whether we are exchanging time keeping signals or not) are Doppler effect and signal delay. The signal delay is, indeed, a function of the spatial separation and thus "path length dependent". What we are teaching, instead, are unphysical coordinate transformations. A local observer does not observe Lorentz transformations, which are independent of the direction of motion. The local observer sees Doppler, which has blueshift for approaching and redshift for retreating objects. He sees an immediate change in the flow of time of external clocks whenever he changes his velocity whereas the remote observer watching a velocity change will only experience this after a finite signal delay. These are the actual physical effects that lead to the twin paradox, it is not caused by abstract Lorentz transformations.
    1
  3091.  @alexanderkohler6439  Did you notice that the metric framework is a little ambivalent, if not outright schizophrenic about spacetime? For any two reference systems we insist that we can only measure relative velocity against a second material reference point (which is experimentally correct), but then we immediately abandon this very strong physical requirement by claiming that once we have this we can interpolate an arbitrary number of intermediate points with GM air hooks anyway and everything is an abstract integral. For me, as an experimentalist, that's a very strong claim and in some sense a little dishonest. I rather argue with continuously observable physical effects alone. Those are Doppler and signal delay and everybody who has a two-way radio and a clock can verify both at all times locally. No GM air hooks needed. It's also how NASA navigates the solar system, by the way. They don't unroll extra long tape measures between the planets as the spacecraft are flying out there. It's all done with Doppler and clocks.

  3092.  @alexanderkohler6439  That Riemannian manifold only exist on paper and in your mind. So do real numbers, of course. I find that theoretical guys often have religious beliefs about their structures. They are not real, kids. Nobody has ever seen a manifold. What you are seeing in the night sky are stars aka giant balls of hot plasma. They are not mathematical symbols. Those are only used to describe the motions of stars.

  3093.  @alexanderkohler6439  A clock is a local energy reservoir and a mechanism that disperses this energy in small, usually equal amounts towards infinity (nuclear clocks do it in unequal amounts as their energy reservoir is decaying exponentially). It is that in classical physics, relativity, general relativity and even in the jewelry store that sells hand made swiss watches for the rich stupid guy who doesn't know what to do with his money but can't get himself to donate it to hungry children. Dude... what a clock is has ABSOLUTELY NOTHING to do with how energy flows in space with/without gravity. All good clocks behave the same. Unless we work for NIST and are in the business of designing the world's most precise clocks we do not care whatsoever how a clock works and what it does. It is of no interest to physics proper. Have you ever taken even one experimental physics class? You are utterly confused about the issues here. ;-)

That's the only class I ever got an A+ grade in... so I must have been very interested in the subject at one point. That was a very long time ago, though. ;-) Both books are standing about six feet from me in my bookshelf, right now. That was approx. $300 for textbooks, back then. Few students bought them because they were so expensive. But I am sure you have your own personal copies as well? Did you at least seem them from afar in the physics library? ;-)

  3110.  @TravisMedia  There are rational countries, e.g. in Europe, where higher education is (basically) free. I got a physics PhD from one of the world's best universities and I didn't pay a thing. In the end they paid me more than I ever spent on books and other costs for my masters degree by providing me with several years of a nice teaching assistant salary.

  3111.  @TravisMedia  My parents did with their taxes. That's no different from them paying for roads, hospitals and the police force, which are all public services that the civilized world needs. The delusion that higher education has to be for the rich only or for people who are willing to get into debt works exclusively in a country like the US which gets most of its educated workforce by immigration. I used to work at a US national lab in the past. On the introductory tour our tour guide pointed out that we would meet scientists from all over the world... half the PhDs in that lab were foreigners at that time. What does that tell you? :-)

  3112. The chemical scale can be understood as being "set" by a couple of things: the speed of light, Planck's constant, epsilon_zero, the electron charge, the electron mass. None of that really matters as the values of these constants depend on our choices of physical units. They are only "uneven" numbers in SI units, which are really engineering choices. Set c=1, h=1, m_e=1 etc. and you will find that the only "constant" that remains is the fine structure constant which is the famous 1/137. That is the only "unexplained" mystery here. What sets that? We don't know. We don't know what sets the ratios between electron and proton masses, either, because for that we would have to know what sets the interaction strength of quantum-chromodynamics. There are, in total, something like 21 such ratios in the current standard model of high energy physics and if supersymmetry exists, then there could be dozens, if not hundreds more of such free parameters in the low energy effective field theory.

  3116.  @shariffliasa1961  Oh, there are a lot of natural resources in Afghanistan. The problem is that having a mineral deposit is not the same as having a profitable mining operation. Opening a mine today costs hundreds of millions, often billions of dollars and it usually takes decades to make it profitable. Afghani people have neither the treasure nor the necessary peace to afford either. Now, they could hope for China to come in and do it for them and China might be foolish enough to try, but then... if you do business with China, then usually China keeps the money and you are looking at nothing.

  3122. The universe can not have a wave function. A wave function requires an ensemble of quantum systems. One can not make copies of the universe and it's not even a system. Wheeler was peddling the "wave function of the universe" idea without actually thinking about the implications. I suggest you try to do better.

  3123.  @philweight3480  That Wheeler was a big fan of the "universal wave function" can be checked easily in his papers about it. Why are you telling me that you don't know the literature? I don't care about all the things that you don't know about. :-) That we don't have a means to recreate infinite copies of the universe is about as hard a fact as they come. ;-) That the universe is not a system follows from the definition that physical systems can exchange energy, momentum, angular momentum and charges between each other. The universe can, also by definition, not do any of that. OK, kindergarten science is over. Please report to Mommy for feeding, bathing and bedtime. ;-)

  3168. No, that's not how it works. For starters you don't have particles. You have systems that do or do not have quanta of energy. In case of an entangled photon pair the system is the physical vacuum and there are two quanta worth of energy in there. There is no difference between the two. To nature they are completely indistinguishable. So if one of these quanta get measured, i.e. the energy gets removed from the field, the there is one more quantum of energy left. Because of angular momentum conservation the total angular momentum of those two quanta has to add up to zero, which causes a correlation between the two measurements.

  3169.  @KenMac-ui2vb  A big name in theoretical physics would be Edward Witten. You won't see him around here. He doesn't give a frell. Sean MWI Carroll, Sabine Trollenfelder etc. are completely irrelevant "personalities" in the field of physics.

  3170.  @Neohedra  Sean Carroll is preaching, nay evangelizing MWI. Sorry to say, but that makes him a total nutcase. That doesn't mean he can't do math. I am sure he can, but physics is more than just math. It requires you to know what the math means. Sean Carroll obviously does not. With regards to textbooks on quantum mechanics... the overwhelming majority of current texts on quantum mechanics are explaining it wrong. The math is all correct (maybe with exception of one little thing and the usual typo/honest mistake), but if you think that you can learn "what quantum mechanic is and means" from undergrad textbooks about quantum mechanics, then you are in for a rude awakening. Almost every text out there teaches you the how but not the why. That's what they mean by "shut up and calculate". It's a perfectly fine strategy for creating undergrads who will never have to understand fundamental issues, of course, but it's NOT fine if that leads to a physicist telling the public that the world keeps splitting at every corner. It isn't. It's much, much more simple than that. Also extremely boring.

  3174. The "length" of a trip isn't zero. It's would just take zero Eigentime. The two are not the same. Even light "knows" that by counting wavelengths. Since the number of wavelengths between two points is a scalar, it's the same for all observers. So while light doesn't have time, it has length.

  3183. You don't. OOP is a documentation technique for your architect. It's also the short leash that he puts you, the programmer, on. So if you don't have an architect and you are a single developer, then OOP does very little for you, especially since it has very few natural use cases. Only academics like to pretend that the world is organized into classes. Most of the world is actually organized into actors and state that is being acted on. That's a far better way of thinking about most complex applications, especially ones that require concurrency.
    1
  3184.  @Franksmoney  OOP is an absolute "must" because it is an industry standard religion. One can't get around it if one wants to work in the industry, but I think it's still a good idea to get a different perspective on it. Don't get me wrong... a large team with a good architect can produce a quality solution with OOP. It's just not obvious that it's the OOP that mainly contributes to the success and not the quality of the team. I would think it's usually the latter. A poorly chosen team with an inexperienced architect will falter and fail no matter what strategy, engineering principles or patterns it follows. Programming is a creative profession that requires, first and foremost, experience. One can't replace that with canned solutions. Software for autonomous cars is certainly a special case because it requires extremely high fault tolerance. We are probably talking about one error per billion hours or less. The problem there, in my opinion, is test coverage. You can see that in Tesla's problems. They are testing on user data from their own vehicles... which is why autopilot likes to run into walls: that case is simply not part of a user generated test bench. People do a lot of shit on the road daily, but they are not driving into walls. ;-)

Why in the world would I not be? I am an immigrant myself. Twice, actually. I was a kid when my parents got out from behind the Iron Curtain. That allowed me to study physics in Western Europe. When I was done with my PhD I came to the US. This entire "Immigrants are taking our jobs" argument is total bullshit. When I came to the US 40% of the PhDs in those national labs were foreigners. The US simply doesn't make enough PhDs. It also doesn't make enough strawberry pickers. We need millions of people who will come here to make a better life for their children. Those children will go to school, then college. They will become doctors, lawyers and executives. THAT is how you make a country successful. With education, not with hate.

  3229. You are absolutely correct. I am usually going even one step further. I keep all state in a single global struct called s. That way I always know when I manipulate state because in the code it reads s. or s->. Local variables don't start with s. While I would not advocate for this in multi-person teams, for code developed by a single developer making scope explicit this way is very handy. I always know when I am doing something dangerous or possibly plain stupid, even years after I wrote the code.

  3233.  @BlackEyedGhost0  There is literally nothing to split. Structurally the phenomenology of this universe is fully understood. It's worthwhile to point out that Galileo might already have had the Theory of Everything around 1630, when he basically gave an equivalent of Einstein's Elevator to express that relativity was an important property of nature. He could not have known just how important it was, but it took us 400 years to go from his relativity principle to a fully worked out theoretical framework that can elaborate the consequences of relativity systematically. It took this long because one can not just sit down with pen and paper and guess ones way through these equations, even though in hindsight the math is pretty obvious. We always need observations and experiments to guide us step by step. That is why it is so unfortunate that the public discussion is driven by pen and paper theorists rather than the people who are actually designing experiments (they are busy and don't care about public outreach). The public thinks that physics is very esoteric. In reality everything that happens at places like CERN is rather hands-on and professional. Critics like Sabine are, at best, driven by their frustration with the slow progress at the experimental front... but that's a matter of technology and investment. One can't go from Galileo's telescope (which was worse than the worst ten bucks binoculars are today) to JWST in a generation. One can't go from his fall experiments to LHC without centuries of effort by millions of people. That's just the price of knowledge.

  3247. It's not who but what. What does the measurement? Infinity does. It adds an infinite amount of phase space, which freezes the quantum state to one possible outcome (the one measured at infinity). You can find this explained in textbooks as early as 1932 (Probably earlier, but von Neumann's book on quantum mechanics from that years is the earliest literature that I have seen on the topic. The relevant explanation is in chapter five or six if I remember correctly. I haven't read the book in many years.). What causes your agency (we don't have free will otherwise I could wish for world peace right now an all the idiots would put their weapons down)? Relativity does. That you won't find explained in any textbook because physicists don't care about the source of philosophical terms, but you can easily see it in every spacetime diagram. Look at the causal dependence of your local future and your forward light cone. If you think about it long enough, it will come to you why this allows for agency. :-)

  3248. You are not allowed to access the contents of the box. That is what "isolated" means in physics. Chemistry is also of no use here because it is always focused on the statistical mechanics average, which is a short term approximation (short compared to the age of the universe, but long compared to the molecular vibration and collision time scale). The actual physics here happens on the Poincare recurrence time scale, which is much, much, much longer than the age of the universe.

  3250. This has nothing to do with theory. Gravity simply doesn't behave like all other forces do.

  3251. It's much more simple than that. The entire story is made up. If we believe Wikipedia, the high speed camera was operating at 1ms shutter speed. An object moving at 66km/s would have been spread out over a 66m distance in that exposure, making it most likely invisible. If the cover was clearly visible on any film of that time, it was going a lot slower. That is also necessitated by the acceleration mechanics which works exactly like the deceleration mechanism in the atmosphere. The shock wave of the explosion did not go at 20 times the speed of sound in the iron or it would have completely dispersed this object within the bore hole, already. So would any radiative ablation based acceleration mechanism. One can imagine that the object was accelerated to a few km/s, in which case it would have survived its journey just fine. If it was never found, then it already got destroyed during the explosion.

Without the last two conditions all we are getting are tons of by-products that don't contain the actual physical information we are after.

  3307. Superposition does not "exist" at all in a physical sense. It's a property of the theory, not a property of nature. You have seen this phenomenon before, by the way. Superposition in quantum mechanics is EXACTLY like the description of vectors as linear combinations of base vectors. What linear combination we need to make a given physical vector depends on the choice of the base (and we can determine the coefficients with a simple "projection" procedure by taking a scalar product between the base vectors and the physical vector). In the exact same way the "superposition" of the wave function is a linear combination of base states. Which base states we chose is irrelevant and nature does not know anything about our choices.

  3331.  @2tehnik  No, QFT doesn't use measurement in the sense of non-relativistic QM. The only relevant quantities in QFT are scattering matrix elements and those have a perfectly natural interpretation in terms of plane waves coming in from infinity being scattered back to plane waves that are going out towards infinity... which is exactly the same as what our eyes do... plane waves from a light source illuminate an object, which then scatters the light back and we look at it and can tell by the colors and shapes what that object is. Turns out that nature behaves the same at the deepest level as it does in everyday life. All the QM measurement stuff was always just decoration on top of what nature prescribes herself.
    1
  3332.  @2tehnik  All the measurement bullshit comes from people who didn't study relativistic quantum field theory or, if they did, lack the intuition to connect it to the fundamental questions of "reality" in quantum mechanics. Historically the study of quantum mechanical systems basically split at the end of the 1920s, shortly after the more or less final version of non-relativistic quantum mechanics was agreed upon. A number of physicists who were interested in low energy systems like solid matter and atomic and molecular spectra kept working with the non-relativistic theory, which can achieve reasonable accuracy for a number of problems but suffers from (mostly imaginary) interpretation issues because it is not a good theory of the world in general. It just happens to work if we squint and don't care too much about certain details. That's exactly how classical mechanics works in comparison to relativity. It's conceptually false but still good enough for many simple problems. The more serious faction of physicists like Dirac, however, realized immediately that non-relativistic QM was both insufficient and a kluge. They began to construct relativistic versions of the theory, initially very much in the style of the Schroedinger equation. These early attempts produced enormous mathematical problems and were very hard to work with. More importantly, they did not reproduce the plethora of ever higher energy physics data that came from ever more energetic accelerators easily. It took these physicists twenty years (all the way towards the late 1940s) to develop mathematical methods that could tackle non-trivial problems (like Feynman's path integrals and Feynman diagrams). It took another twenty years (bringing us closer to the 1970s) to tackle divergence problems and to develop what is called gauge theory that is the backbone of the standard model of physics. As a by-product of these mathematically very challenging problems the comparatively trivial issues of quantum mechanical measurement etc. are falling by the wayside completely. It is trivial to explain the source of uncertainty in a relativistic worldview and it is just as trivial to explain why the world seems to reduce to classical physics on its own without somebody staring at it all the time. So why are there still people who just can't take the relativistic quantum field theory "yes" for an answer? Beats me. Some people just don't want to get out of their Schroedinger comfort zone, I guess, no matter how poorly it matches to actual reality.
    1
  3333.  @2tehnik  The uncertainty simply stems from the fact that in relativity outgoing waves can't return. A local phenomenon that sets off a wave that propagates at the speed of light is automatically entangled with something that is irreversible and the state of which is therefor unknowable. Classically speaking one can't catch a light wave in any coordinate system (because light waves always move at the speed of light), hence whatever energy, momentum, angular momentum was transferred to that field is lost forever. It's not much of a mystery, really.

Did you ever believe that they really paid that much for a coffee maker? OK, so if you are smart enough not to believe that, then can you imagine that something similar has been going on with the Apollo, Shuttle, ISS and now Artemis programs? You are simply looking at the real cost of a cold war that has never stopped and that currently is on the brink of becoming a hot nuclear war.

  3372. Because of the strange way they define a dud... as basically transparent. No such duds exist in the real world, of course. The simple fact is that these folks were too smart for their own good. They tried to manufacture a quantum mechanical system out of a classical one with a slightly weird definition. IMHO it doesn't work because the system doesn't ever become quantum mechanical (no system does in which Planck's constant doesn't show up somewhere). The bomb explodes whenever it absorbs field energy and it doesn't when it doesn't. That's no different from a match (which lights when you rub on it or it doesn't when you don't) or a piece of black cardboard that is either inserted in the light path or it isn't. The fact that it's a bomb is simply show. It has absolutely no physical significance. We can build as much interferometer around such a classical absorptive system as we want, it never becomes the equivalent of a quantum mechanical system like an atom, which can not only absorb field energy by undergoing an optical absorption event but then also give that field energy back by a symmetrical emission event. That is the true physical difference between the bomb scenario and an actual quantum mechanical object like an atom.

At a slightly deeper level you can understand quantum mechanics as a direct consequence of special relativity, which means that a classical property of a classical background already carries (almost) all the information about the quantum world in it. The structure of the quantum theory is fully determined by SR, the only remaining degrees of freedom seem to be the choices of effective symmetries at low energies (aka as the QFT and string landscapes).

  3408.  @Tense  I have given this explanation a million times before. There are no particles for starters. People are simply not paying attention when we explain to them that "Quanta are small amounts of energy." in high school. How hard is it to remember six words? Moreover, that energy comes at you at the speed of light (all quantum fields are relativistic), which means that nature can not give any warning about when and where that energy will be. That is the trivial reason why quantum mechanics is uncertain (i.e. unpredictable). That's not even quantum mechanics. This happens in classical scenarios as well.
    1
  3409.  @Tense  Dude, you could have learned these things in high school, IF you had been paying attention. That's not an ad hominem but a fact. And, yes, physicists are pulling a horrible educational con-job on you by calling quanta "particles". It makes understanding quantum mechanics nearly impossible. That is the central sin of modern physics. It still tries to use 19th century concepts and language for phenomena that are simply not adequately described by either. You have to let go of materialism completely here. Physics is all about system properties. The four locally conserved system properties are energy, momentum (relativistically it's really one four-vector), angular momentum and charges (electric, leptonic, baryonic etc.). None of this has anything to do with brains, working or non-working. It's all just consequences of symmetries.

  3411.  @Tense  I am not an educator. I used to be an experimental physicist, so I have actually "seen" trillions of quanta myself. I have zero interest in teaching, the authoring of textbooks or the editing of YouTube videos. I am simply telling you what reality looks like because I have actual experience with it. As part of that I can tell you why your high school teacher would actually have been your best bet to understand quantum mechanics at the fundamental level and what went wrong historically with the teaching of quantum mechanics at the university level. Why is this important to me? Because I am one of the victims of that failed teaching strategy. You can't even imagine how confused I was after my own introductory QM 101 class. Not about the math, that's easy enough, but about what the math means. That confusion lifts after you become an experimentalist with an interest in the topic, but one should not have to spend years in high energy physics labs measuring energy, momentum, angular momentum and charge transfers between systems to arrive at the conclusion that the six word "Quanta are small amounts of energy." high school level description opens up all of quantum mechanics to a completely trivial understanding by absolutely everybody who remembers the 13 word high school definition of energy (Energy is the ability of a system to perform work on another system.). Yes. Physics is THAT simple but we are complicating it with endless numbers of useless layman books and videos about it. ;-)

  3412.  @Tense  Why are you confused about a total of 19 words? Would you like me to summarize it for you in a way that everybody can remember?

From that it follows that a quantum is that which allows us to carry a tiny piano to the fourth floor of a very small building. :-)

  3437.  @wrathofcorn  Dude, if you know QFT, then you know that nature is NOT non-local. You will know that there are no particles and that the theory is all about energy transfer, that you don't need Bell and his nonsense and that it all follows nearly trivially from special relativity. Maudlin doesn't know any of that. ;-) You clearly feel a need to defend Maudlin. And I feel a need to feed a lonely person on the internet. ;-)

  3452.  @Langkowski  Light isn't "made" of photons. That's a false semi-classical mental model that tries to apply the principles of classical atomism to a purely quantum mechanical system. Photons are quanta of energy. They only "exist" as irreversible energy exchanges between the source and the electromagnetic field in emission and the electromagnetic field and an absorber in absorption processes. There are, however, no photons in the free em field. The theory does not pretend that there are, either.

  3462. You are correct, except that you are also completely wrong. Paradigms like OOP and FP are NOT EVEN slight advances. They were never relevant to the actual problems of software ENGINEERING, which is to a) get it done, b) get it done on budget and c) get it done on time. All of these "prescriptions" are are indeed steps backwards because they restrict the software engineer from finding the actually best engineering solution to a problem (i.e. the one that gets it done, gets it done on budget and gets it done on time).

  3463. No, the majority of data input is not wrong, but when it is wrong, it is usually spectacularly wrong because then we are dealing with data that has been curated by humans who themselves can not admit and correct mistakes. That is not the actual problem, though. The problem is that LLMs separate learning from transforming. It is not possible to teach an LLM to "forget" wrong responses and to correct its learned data set.

  3470. Banking is an exceptionally low risk business. Technically there are zero bank failures in most years. The assets are fully protected and they are merely being taken over by a bank with better management. The only "problem" we have is the unwillingness of the government to insure more than $250,000 through the FDIC program. While that amount is sufficient to cover most private savings accounts, it is already insufficient to cover e.g. payroll accounts of anything but the smallest companies. THAT is a problem, but it's a problem made by people with your mindset. All we have to do is to raise the amount to e.g. a billion and this problem goes away completely.

  3497. Technically "charges" do not matter in optical media for visible light. What matters is bulk polarization.
    1
  3498.  @destroya3303  Why not? Optical properties are usually not caused by free charges. They are caused by the polarizability of the medium. The more polarizable a medium is, the higher the epsilon_r and the lower the effective speed of light in that medium. Frequency dependent polarizability leads to chromatic effects (like the very pretty "fire" of diamonds, but it's bad thing if we want to make lenses for optical instruments). There are rare cases of natural materials where free charges do, indeed, play a role. Have you seen fluorescing diamonds? They have a pretty blue hue when exposed to UV light. (even though this fluorescence lowers the value for jewelry because it reduces the visibility of the actually desired chromatic effect). If I remember correctly it's caused by a so called color center, which is an electron that is trapped at the site of a nitrogen dopant atom in the diamond's carbon lattice. Other examples where free charges matter for optical materials are LCDs. There the free charges on the electrodes in the screen cause an electric field that re-orients the chiral molecules of the liquid crystals.

  3500. It's simply an expression of the fact that it's never the language that is unsafe. It's always the programmer who is unsafe. Every correctly implemented language does exactly what the programmer was asking for. The problem always rests in the fact that what the programmer actually wanted was not what he was asking for. The "bug" originates in the disconnect between what we think will happen and what actually happens. That is a non-solvable problem in Turing complete languages: there is no program that can prove that an arbitrary Turing complete program is correct. Such a prover simply does not satisfy the halt problem.

  3527. The electromagnetic field is massless (or at the very least has extremely low mass) and is almost perfectly linear at the frequencies of the optical spectrum, i.e. it does not have any noticeable self-interaction. That's why it can propagate almost unchanged through the entire observable universe.

  3528. That people become jaded has nothing to do with the media. It's a necessary human adaptation to bad news. A person who dwells on bad news has no emotional energy left to deal with reality, so we simply learn to screen it. 95% of the house burning down is, by the way, the evolutionary normal for every species, not just humans. 5% remaining is perfectly enough to rebuild. The human population was approx. 400 million in the 16th century... that was without modern medicine. With modern medicine we could replenish ourselves within a few hundred years. Not that we should, if it ever came to such a collapse. We need higher quality, not more quantity.

What Ukraine needs isn't dumb shells, anyway. It needs cheap smart shells. Eventually they will produce them themselves.

There is nobody to talk to. Russia was betting on a three day war that would have taken Kiev, eliminated the government of Ukraine and replaced it with their own henchmen. After that didn't work they didn't have plan B. They still don't have a plan B. The curious thing is that the US was basically telling Russia and the entire world "Stop this bullshit. We can see you.". That was the only viable off-ramp Russia ever had. After that they had to go all in and they are discovering that they never had a winning hand.

    1
  3576.  @GravemindHD  Will I? I am fully vaccinated and boosted, I am wearing high quality masks and I don't go close to people. You don't get diseases just from looking at people across the room, you know. The disease relies on you to do shit. And you did. It only takes one time. :-) And did you notice how the Chinese eradicated it in twelve weeks by locking people in? Social distancing works... (collective) you are just not intelligent enough to use it right. :-)

  3577. Why are you telling us that you have been the crazy aunt for years? We don't need to know that your family has disowned you. ;-)

  3578. So you are basically just telling us that you don't know the actual definition. OK.

  3579. China is always close to making a fool of itself. ;-)

  3580. Space isn't propagating through anything at all. Space doesn't have a velocity to begin with. Why? Because nobody has invented GE space hooks, yet. ;-)

  3581. That's actually a good point. In the theory that's called "preparation". Schroedinger assumes that we can prepare a classical state. I kind of doubt that we can, but we can prepare a density matrix of a classical state, which is probably good enough for most applications in physics.

  3597.  @billjones8950  1000 years ago? What happened 1000 years ago? You mean the crusades? Dude... only a crazy person uses those as an excuse for anything. ;-) The first crusade was 1096-1099, by the way, so it hasn't even been a thousand years, yet. :-)

  3602. There are no Israeli war crimes because there is no war here. Nobody has declared war on Israel or vice versa. You need to get a life. This is going to be a large scale policing action. If you are obstructing the work of the police, you can be punished. That's at least how it works where I live. We have law and order here.

  3607. @ The problem with housing is size and density. You have to put the same size roof on a mega mansion as is required for a six story, 12 or 18 apartment rental building or condo. Both types of buildings require the same amount of land but one houses ten times more people at a fraction of the cost per person. Of course housing becomes more expensive with that kind of splurge. In the past people had two pairs of shoes, if they were lucky and some had none. Today we have five or ten or twenty. We are throwing perfectly good clothing away because of fashion requirements. In the past a textile would have gone through half a dozen different uses (and owners) before it ended up as a rag doll or a washcloth. Why? Because it was a very expensive and hard to come by item. The use patterns that dominate the modern world have been enabled by cheap mass manufacturing. They are not typical human behavior. Can they be reversed? Unlikely... at least not without an economic collapse.

  3608. Except that those are not Linux devices. They are Apple devices and Google devices. What makes them work is not Linux code but the billions of dollars of R&D that were put in by large corporations. Let's stick to the facts.

  3612. That's cool, kid, but dirty dishes are not the source of COVID-19 infections. People are. :-) My antivaxxer relatives had COVID-19 for the first time around mid-2019 and they had it again a couple of months ago. This shows you that "natural immunity" may last 18 months or so, so if you aren't vaccinated and boosted, your chances of getting it again are growing exponentially, right now. Just give it time.

  3617. What anxiety is that? You don't move your car every five minutes. You drive to work and your car is standing in the parking lot for 8h. You drive home and your car is in the garage for 12h. You drive to the mall and you are shopping for 30 minutes or two hours. What's there to be anxious about?
    1
  3618. And you are saying this despite the fact that you don't even know where sin is defined in the bible.

  3619.  @pravoslavie123  You are welcome to get your bible and check this: the word sin is not even mentioned in Genesis 3. Whoever told you that sin is from Adam and Eve lied to you.

  3632. Lock them up! Lock them up! Lock them up! :-)
    1
  3633. I am sure that sounded really grand inside your head. On the outside it sounds like somebody who is desperately looking for attention. That's no different from Hamas, which was also looking for attention. That neither of you like the kind of attention that you are getting... well... that's just too bad.
    1
  3634.  @lukesimas  And there is the silly person who is threatening everybody on the internet with his invisible friend. Dude, are you for real? :-)
    1
  3635. Exactly. Pure functions are useless except as a tool to reuse code snippets. An entire program can NEVER be a pure function because it would always return nothing (since it is not allowed to change the state of the world even at the end of the computation).
    1
  3636. I agree. Battery electric backhoes are probably not a good idea. ;-)

  3640. Can you give us that citation for a 2005 study that 85% of physics papers are either fakes or very poorly done? See, physics is the only thing that Sabine has been trained in. She knows squat about anything else and I can tell that even within physics she doesn't know all that much.

  3645. We need way more men than we have, actually. The problem is not that. The problem is that most boys don't grow up these days. They always stay spoiled children. That is, of course, the fault of women... your Mom's did a horrible, horrible job not raising you. ;-)

  3646. I never voted for you to lose your mind. That's probably inherited. ;-)

  3647. An NDA is a legal document that defines a "reasonableness" standard for the safekeeping of trade secrets. It prevents both sides from bringing nonsense lawsuits. If you are ever exposed to somebody's trade secret without having a written NDA in place, be very careful. It might backfire if you are dealing with a possessive personality. With an NDA all you have to do is to keep their trade secrets as safe as you would your own, i.e. they can't require you to pay damages for accidental leaks if you abide by the low standards of the document, which are usually trivial. If you are used to keeping your own trade secrets in a file folder in a locked office and you have employment agreements that require your employees to keep their knowledge about your company and its operations to themselves, then you are done implementing security measures for your partner as well. They can't sue you for not keeping their documents in a safe inside a vault inside a military installation with double fences and armed guard towers. ;-)
    1
  3648. Because people make it sound like that. Entanglement is essentially just momentum and angular momentum conservation. You have seen mechanical examples of it in school, you were just not told that some people would call the same boring thing "entanglement" when you got a bit older. ;-)

  3649. And what would that change?
    1
  3650. And there is the troll bot that lies about energy storage efficiency. ;-)
    1
  3651.  @Robert-xs2mv One can achieve efficiencies well over 50% with solar, if required. It's just not cost efficient. What's the point? Physical efficiency is not the goal. Cost efficiency is. At this point the levelized cost of solar energy is on the order of 5 cents per kWh and it will probably fall further to half that much. In combination with agriculture solar energy might actually achieve zero or even negative cost in some regions. Going below that is absolutely pointless.
    1
  3652.  @Robert-xs2mv  Why don't you tell me about how the Earth is flat in addition. Maybe then I will be giving you more attention. ;-)

  3657. There is no need for major breakthroughs as long as Ukraine can destroy 500-1000 Russian soldiers and 50 pieces of heavy armor and artillery a day. It's all just a slow burn.
    1
  3658.  @JoeyBlogs007  They are doing it right now. Ukraine can keep this up indefinitely as long as the West is supporting them with arms. Not a problem. Well... it is a big problem for Russia, of course.
    1
  3659.  @JoeyBlogs007  We can kill at least a billion people in less than an hour with "the better technology". Let's not go there. Let's do this the old fashioned way with small pieces of lead and explosives.

    1
  3664.  @zidaneabderahim7131  Physics isn't theory. Physics is experiments like those at CERN. If theory would work, then the Greek philosophers would have solved the problem a long time ago. They didn't. That you don't understand what the SE does is because you haven't been in the lab. I have talked to plenty of real, very gifted theoretical physicists who didn't understand it and you are definitely not even one of those.
    1
  3665.  @zidaneabderahim7131  If theory would work, then the Greek philosophers would have solved this a long time ago. They didn't. That's why we need experimental facilities like CERN. What you said about this is total nonsense. Please try to educate yourself. I can't do that for you. That is YOUR responsibility.
    1
  3666. Nature is not a theory journal. Phys Rev D used to contain a lot of theory, but there are theoretical journals like "Classical and Quantum Gravity" that would probably be better places for ToE kind of work.

  3675. Hyperloop didn't kill California high speed rail. If anything it has led to a healthy discussion about what can and can not be done with rail systems, even if we assume that we can go to the outer limits of technological feasibility. One can say the same thing about spaceflight. SpaceX is demonstrating that the Saturn V was not the last word and neither was the Space Shuttle. There is a lot of life left in the field and we have people who want to explore that. Having said that, the reason why there is funding for these things is rather mundane and the same why there was funding for the Apollo program: we are in a new cold war (which is the extension of the old cold war, with China replacing Russia). There is a side of Musk that is irrational, but it's got nothing to do with this particular topic. Here he is basically just executing a new phase of clandestine technology buildup for the US government, similar to what another crazy billionaire did in the past.

  3679. Nobody can get out of Gaza right now. Israel will probably eventually filter everybody who wants to get out... but I suspect that men will have a hard time proving that they were not Hamas affiliated.
    1
  3680.  @philips3352  That's my point... the only people we know about who didn't participate in the atrocities are women and children. Will Israel let the men go easily? Probably not. It might take years to process them. Israel has all the time in the world... it is possible that many men will die of old age in one of the camps that will be erected before they will be able to prove their innocence.

The difference is that I don't have to pay for what I don't use. The only reason why banks etc.. are using IBM mainframes are reliability and security. People who aren't running that kind of business process don't need it.

  3709.  @canelo1728  KSA is building nuclear weapons, mate. That takes tens of billions of dollars in funding. "Neom" is the money laundering operation to divert the necessary funding from their internal wealth fund. The project may also be the construction site of the bunkers needed tor the enrichment, weapons manufacturing and ultimately, the hardened delivery system bunkers since neither strategic bombers nor nuclear submarines are an option for second strike capabilities. :-)

  3710. In general NSAIDs have damaging effects on mucosal linings. The mechanisms seem to be different in the stomach than in the small intestine, but they seem to be roughly equally frequent. More water intake might help and constipation can be relieved effectively in plenty of different ways, both with dietary changes and over the counter medications. The potential damage to the small intestine, however, is more worrying.

  3711. And she didn't say that the universe was infinite. She said that Einstein's theory treats it as infinite. Even that is a bit of an overstatement because that is only the case for flat and hyperbolic spaces. One can construct closed universes within Einstein's theory, but even then such a closed universe would be bigger, possibly much bigger, than the visible universe. Which of these cases is realized in nature is not known and may never be known with certainty.

  3715.  @GiuseppeBertini  The folks of the international boxing association who published that press release. Assuming that you transcribed it properly. That would be a horrible PR strategy, especially for boxing, which is conscious of physical differences between athletes. That's why it has weight classes. They would never let a heavyweight punch a tiny guy in the ring, right? It would be irresponsible and counterproductive for the sport to arrange fights between athletes who are not physically at least somewhat similar.
    1
  3716.  @GiuseppeBertini  Genetically "male" is well defined. Males have an XY chromosome pair, females are XX. There are genetic abnormalities with additional chromosomes, like XYY (Jacob's syndrome) and XXX. Triple X females can have a very tall, rather unique (and in my personal opinion masculine) build, so they might have a physical advantage in some athletic disciplines, even though they are "more" female than regular females. Having said that, athletic performance seems associated with more than 200 known genes (and there are probably many more beyond that), so counting chromosomes is a very, very crude tool at the biological level. Of course athletic performance measurement is, on some level, genetic discrimination. Some people are born more athletic than others. A genetic handicap is impossible to overcome with any amount of training in the world.

  3717.  @GiuseppeBertini  All I am saying is that sports is "unfair" one way or another. This particular case may or may not be any more egregious than many others where the difference is not one of gamete production.

  3718.  @GiuseppeBertini  So that validates Dawkins and is pretty much the end of the story. Why a trans athlete would do that kind of thing to him/herself is another question, though. To me it's really not much different from doping. If you can't win without cheating, then don't compete. There isn't much else to it.

  3719.  @GiuseppeBertini  Swyer syndrome? That's one in 100,000 females and there are two cases in parallel? No offense, but that is statistically somewhat unlikely... and of course nobody on the teams knew about it. Sure, sure. ;-)

  3725. Integration is a necessary engineering strategy to save cost while adding features. A car from the 1950s would have killed its passengers in most serious accidents and people were contempt with that. Then we implemented ever more safety features and cars were killing ever fewer people. This makes car design harder and more expensive. Designers have to find cost savings to make up for the price of safety.

  3729.  @martinko4086  Yes, I do not have a clue because I actually know that there is no "one China" any more than there is "one America". There are highly developed Chinas and Americas with enormous financial and industrial capabilities and then there are back-country Chinas and Americas that are utterly forgettable in terms of development. Unlike you I am not blessed with the ability to take averages and to believe religiously that that's sufficient to describe reality. I am so stupid. Or maybe you are. Yeah. I think we go with the latter. Take care.

They would be obliterated within days if they tried to attack NATO militarily. NATO's contributions to Ukraine's intelligence is what has neutralized most of the Russian moves. They are under 24/7 surveillance and NATO is giving Ukraine real time targeting information. Russia is learning the hard way that it can not pound itself out of that kind of strategic situation.

  3773. I had a Linux PC running in our physics lab for over a year around 1995. The machine was only interrupted by a power outage, so one can probably say that the OS and the hardware were not the problem. I have a RPi that ran continuosly for a little less than a year before I had to move it to a different place. None of those machines were or are safe against hacks, of course, so "uptime" is pretty meaningless. It simply means that the OS background processes won't terminate and none of the drivers will crash. Once loaded with crappy applications the picture is probably not all that pretty any longer. Run Skype and you have to reboot your machines anyway to solve audio/video driver issues. The feature that mainframes used to have that never existed on the PC platform is that one could keep data loaded into main memory while unloading/reloading/updating software. That requires a completely different memory and OS architecture. Unless you are running a bank or an insurance company, that's a rather useless feature to have, though.

  3775. Is it possible to get hired? Not by a quality employer whose name will look good on your resume. For that you need at least four years of college (and you must have written a thesis). Even better would be PhD in CS. Will some small Mom and Pop show that needs a website pay you a couple hundred bucks? Maybe, if you are lucky. But is that really what you want to do with your life? Seriously? Now, we can have a discussion about why it's irrational for countries like the US to charge for college, but that's politics that won't change for a generation or longer, so that's not going to help you. Take a deep breath, get somebody to pay your education for you and do the four hard years (8-12 if you want a PhD). Millions have done it before you and you can, too. Don't believe for a moment that you are special. You aren't. At most you are a high performing fool for believing that life will give you something for free that others have to pay for.

  3787. Why not? Interference is the result of the absence of interaction. All it says is that electromagnetic waves are extremely linear phenomena.
    1
  3788.  @kennethgee2004  Yes, that things add up in a linear fashion is the absence of interaction. I know that it is counterintuitive, but if you think about that for a little bit, then it will sink in, eventually. Just look at the wave equation. You can see that there are absolutely no mixing products coming out of there. In a self-interacting non-linear field two wave packets with frequencies f1 and f2 will produce mixing products which have the frequencies (f1+f2) and (f1-f2). If electromagnetism were like that, then we would be looking at a totally foggy world with all kinds of weird halo effects wherever two beams pass trough each other. I know what they say about single photons in the double slit experiment, but that's simply total nonsense. Photons only exist in two locations in this experiment: at the light source and at the detector. There are no photons anywhere in the free space between. That's why the double slit is not even a quantum experiment. There is, unfortunately, a long history of Chinse whispers about this experiment that get repeated by pretty much everybody who hasn't spent any time on actually thinking about this.

  3789.  @kennethgee2004  Linear is linear, my friend. Think about it some more. As of now you are very confused about what "interaction" means.
    1
  3790.  @kennethgee2004  The classical wave intensity is simply the average photon density in this case. Photons are energy and energy is the square of the amplitude. Amplitudes add up in a linear fashion, but energy is zero at all times in those minima. There is simply no field at all where you can't find a photon. Your ontological problem stems from the fact that you have been schooled to be a physical realist for classical waves, i.e. you think that classical amplitudes actually exist in nature. QFT proves that they don't. They are just as un-real as the wave function is in quantum mechanics.

  3822.  @moskitoh2651  My teacher knew that science is not religion. Having said that, the mathematical structure of quantum mechanics is inescapable. It's based on the same assumptions (independence) that probability theory is based on. Independence of measurements can be tested. If an experiment violates it, then it will show up in the data, so we can tell empirically if the formalism of quantum mechanics is applicable or not. In many cases it is not and then we can use arguments that deviate from the formalism but are still returning the correct answer. An important, albeit virtually unknown problem of this kind is the Mott problem. Your problem is that you don't know any of this. You are currently just waving a giant foam hand around that has absolutely nothing to do with either physics in general or quantum mechanics specifically. I call that "the poetry of intellectual laziness". ;-)

  3823. Yes, that works great for the survivors. It doesn't work at all for the dead. ;-)

  3824. You are halfway there with that, but the failure doesn't lie with theoretical physics. It lies with experimental physics. What the theorists are talking about today is experimentally simply not accessible. Does that invalidate how we do theory? No. It does remove it from the realm of the testable, though. So instead of calling this theoretical physics, maybe one should call it mathematical physics. As such it is perfectly fine.

  3825.  @davidmoulton1991  The people who are calling "the academic establishment corrupt" are usually those who weren't successful in becoming academic establishment. That's an empty accusation with zero actual evidence. I did work with "the academic establishment". I went to lunch with these people. I didn't sense any "corruption". Nothing they said or did met any standard of moral failure in my eyes. Like you said... some problems are just hard and they can't be solved right now. The century between the discovery of spectral lines and the development of quantum mechanics was such a period. Today I can explain the physics behind atomic spectra to a smart high school student but back then not even the smartest people in the world could solve it. Your last remark is also correct. Loop quantum gravity is just as unverifiable as string theory. It is a tautology that ANY possible theory of quantum gravity would be unverifiable right now because quantum gravity simply doesn't leave any experimentally accessible signatures for the time being. This may change sooner or later because there are some mighty skilled experimentalists who are working on those experiments right as we speak.

  3857. The spin projection we measure is the only spin projection there is. The system doesn't have a spin projection before the measurement takes place.
    1
  3858.  @atklm1  Let me repeat this, again. There is no spin projection before the measurement. The only "reality" in quantum mechanics is the reality created by measurements. That is no different from classical mechanics, by the way, except that there it doesn't matter if we pretend that things that have never been seen "exist" or not. That logical error has no lasting consequences in classical mechanics. In quantum mechanics it leads to contradictions. The result of a measurement is NOT random. We know what happens when we introduce random variables in physical systems: they create dissipative phenomena and they destroy energy and momentum conservation. None of that happens in quantum systems, which means that it can NOT be random. The result of a measurement is instead correlated (entangled) with the state of the measurement system. We can not know precisely what that state is because that would require another measurement and so forth ad infinitum. The microscopic explanation for why this can't be any other way can be found in relativity: every quantum system is entangled with the future, which means that the "local, present state" is necessarily uncertain unless all of the future is known. I think we have plenty of evidence that the future is not knowable.

  3867. What is the objective of building empty suburbs that don't even have shopping opportunities? I have been in one of these. I went out and wanted to buy some supplies. I couldn't find a single store. A Chinese man came towards me with shopping bags, so I asked him where the supermarket was. He said it was 40 minutes on the bus to the next store. So, these are not for living and they are not for profit. Then what, exactly, are they for? Please explain.

Apart from the numerical libraries that are being shared and a few fairly basic OS components for scheduling all the code on a supercomputer is pretty much tailored to the user's needs. That's also a lot more interesting that full stack design, where every programmer basically reinvents the same old boring user interface, database and backend code over and over, again.

  3875. Loans China has given to other countries were mostly loans to China. All the belt and road initiative loans went back into the pockets of Chinese companies. It's a hidden Chinese debt problem. On the other hand, at $6000 per capita China's internal loan problem seems manageable. I am not sure if that includes the loans of local governments, which seem to be higher and not covered by revenue.

  3883.  @wesjohnson6833  The problem with quantum mechanics is that it does not obey the point-in-space-point-in-time-rinse-repeat event ontology of classical mechanics in several different ways. For one thing we can't do a rinse-repeat. Once we make a quantum measurement we have changed the system irreversibly. More troubling is that "a measurement" is not actually an event but a process of at least finite length for the mentioned reason. Even worse, in my opinion is that we teach QM ontology exclusively in the non-relativistic case where "A makes a measurement before B" seems to have a unique well defined meaning. Except, of course, that we live in a relativistic universe and "Who's first?" in general becomes an observer dependent question. The relativistic version of QM only has to keep the causality of relativistic spacetime alive, which is different from that of Galilean spacetime. So, yeah... combine all of that and try to form a really solid intuition for the phenomenology. I have not been able to achieve that in four decades of thinking about it. I am not saying it can't be done... but I still can't do it myself.
    1
  3884.  @wesjohnson6833  Exactly. In some respect we are worse off than they are, though. Experimental data and observations that were made during that period eventually allowed the next generation to break the seals of nature wide open. Today we lack the next series of key observations and they seem nearly impossible to make in areas like high energy physics (if there is really a great energy desert to the GUT level) and quantum gravity. There is bewildering stuff, of course, like dark matter. Now, it may turn out to be very weakly interacting fields, after all... but if we can't find those, oh boy, then we are in real trouble.

  3886. Every professional programmer has occasionally used "tricks like these", at least if he ever grew past an entry level job function. There is nothing particularly unsavory about them. If you know how to use pointers, you can get creative with them. Technically speaking pointers are nothing other than your CPUs indirect addressing modes in a somewhat higher level language construct. Why are they there to begin with? Because CPU instruction sets without them is a half-step towards an insane language like Malbolge: they are almost completely useless in practice except for the most trivial programs.

  3894. There are two sources of discreteness in quantum mechanics. One is the measurement process. A measurement is an irreversible change of field energy. By that we mean that no matter what happens in detail, there is a long term (more precisely infinitely long) change in the energy distribution between the system under measurement and the measuring system. The "result" of that change, per special relativity, is a change of energy and momentum, but it can also involve angular momentum/spin, electric charge and other conserved (or nearly conserved) quantities. Logic necessitates that such a one time change has to have a discrete (single value) property. That, of course, is merely the source of discrete measurements. It is not the source of quantization of the fields. For that we also need the quantization of angular momentum/spin. I don't have a really good fundamental reason for that, even though I know that theorists have tried to derive it from deeper principles. It may be due to symmetries of spacetime. It may have to do with the partition properties of physical systems that require a theory that obeys something like the law of conditional probabilities, which can be used to derive the linear structure of quantum mechanics. It may be the intersection of both or something physically deeper, still.

  3911.  @damon2550  Not really. It's a sad state of affairs, actually. We have known since the late 1920s, early 1930s latest, how quantum mechanics works and we have still been teaching it all wrong right from the beginning. The very people who figured it out did their worst to make learning quantum mechanics as hard as it can be by surrounding it with language constructs that give everybody all the wrong mental images about it. I did experiments with different AIs and they all stick to the language in the textbooks that they were trained on. That language is, unfortunately, false. By that I don't mean that the textbooks are false. All the formulas, the derivations, the results are all correct. It's the meaning of the formulas that is not at all what the textbooks claim. Their authors have simply been repeating the same mistakes from the early days again and again. Even the newest textbooks are containing 100 year old ontological errors. It's not a big deal if this happens to such a specialty as quantum mechanics... but I am sure it's not an isolated phenomenon. You will discover the exact same phenomenon in all walks of life. AI is an echo chamber amplifier. It doesn't correct human mistakes. It spreads them out over all of mankind. If people learn to rely on it, then AI will cause a decline of human intellectual effort and it will cement past mistakes for all eternity... or at least until AI learns to correct them for us. I am not sure I am less worried about the latter....

  3930. It's worse than that. Hidden variables were never alive. The tragedy is that what looks like "hidden variables" is an obvious consequence or relativity and Einstein himself couldn't see it. He should have been the first one to point out that the structure of QM follows immediately from the causality structure of relativistic space-time. Worse, Nathan Rosen was a young but very advanced relativist. Even if Einstein didn't notice because of his age and emotional closeness with the matter, Rosen should have seen it in a split second.

  3942.  @chadkincham  Matter isn't made of energy. Energy is a property. We teach that in high school, but it doesn't seem to stick. Maybe you can remember this: If you have a "red car", then "red" is a property of the car, but it's not made out of red. That's in contrast to a "clay brick", where the brick is, indeed, made out of clay. The way physicists use the word "energy" is the way "red" is being used in "red car", not the way "clay" is being used in "clay brick". Yes, photons are energy, they are not corporal objects. Quanta in general are not corporal objects. An electron isn't an object, either. It's a property of the physical vacuum that denotes a combination of energy, momentum, spin, electric charge and lepton number. Until that combination passes from one system (emerging from the physical vacuum) to another system (also emerging from the physical vacuum), "an electron" doesn't exist. If you can remember that, then you will be able to cut through mountains of bullshit about quantum mechanics.

  3943.  @chadkincham  You are not very good as an amateur physicist, I am afraid. :-) That energy and matter are equivalent is Star Trek physics. In high school we taught you (well, at least we tried) that mass and energy are equivalent, which makes a lot of sense, since mass is also a property. Mass and matter... both start with "ma", but they are nothing like each other. Good luck with your further studies. :-)

  3953.  @SpotterVideo  Planck's constant is 1 in every rationally chosen system of physical units. What's the source of angular momentum quantization? Relativity. You can find the derivation of relativistic quantum fields as representations of the Poincare group in suitable QFT textbooks.
    1
  3954.  @SpotterVideo  We start with the Poincare group and then we derive all possible equations of motion that are compatible with it from symmetry principles. Those include classical laws like Maxwell and then it includes the quantum fields of the standard model. The classical laws don't produce universes with matter. There will be no chemistry, no nothing in those. Leaves the ones with h=1. That's universes based on quantum fields. They happen to reproduce all the visible effects. The actual number is based on our choice of the length of the meter and second and the size of the kg. If we chose different base units we can make h=c=1. The only physical constants that we can not reduce to one are the unitless ones like the fine structure constant, which is roughly 1/137 no matter how we chose the units. Why is it that value? Because not all combinations of quantum fields produce self-consistent converging theories. Which do and which don't depends on physics that is currently out of our reach experimentally. That's why people are searching for e.g. supersymmetric fields. They would complement the currently known ones in ways that should explain why it is this particular universe and not some other. And, no, you don't have a model until you can quantitatively reproduce all known phenomena. And that you can't. At this point all you have is bullshit. ;-)

  3968.  @TWak4ord  The galaxies beyond a fraction of the size of the current universe are already out of our sphere of influence, so we couldn't tie a string to them that would drive e.g. a generator, if that's the kind of mechanical analogy that you are looking for. They are already moving away at more than the speed of light from us. What an observer would see over the long term is that space will be emptying out, except for a few gravitationally bound local objects, which will not move away, unless dark energy is increasing over time and then everything will fall apart. At one point that process will probably become so fast that there will be a new wave of matter creation and that is where this "dark energy" will "condense" into new matter and radiation, if you will. So that's really a phase transition from an empty universe into a new matter filled universe. This may repeat cyclically over and over, again. Whether this actually increases the total size of the universe is not clear. Personally I have a feeling that it's more like kneading a finite piece of dough, the "inside" goes "out" and the "outside" comes "in", but, of course, the "inside" is everywhere and so is the "outside". That is very hard to visualize geometrically in a flat space, where something like this can't happen.

    1
  3991.  @afjelidfjssaf  What you are comparing are COMPILER OPTIMIZATIONS, not languages. C is basically refined macro assembly language. It doesn't define all that many operations that do not already exist as native machine code instructions on most modern CPUs in one form or another. It does, of course, take care of memory allocation for you and it gives you a little bit of namespaces (an array or struct are, at the end of the day, just a name space for an allocated chunk of memory). Other languages are doing a lot more in that department, but that comes at a high cost: you lose access to the memory layout, which is not a good thing for performance and security purposes. No, no language can beat assembly, but even relatively primitive compilers can beat most programmers. That's a limitation of programmers, it's not a particularly amazing feature of compilers. I will give you a hint for the future: AI code generation will bypass the structured language level altogether. There is absolutely no need to generate human readable code for AI. It can output machine code directly just as easily. I would go even one step further: we may see AI that will generate microcode and programmable hardware maps directly. Welcome to the human-less future. ;-)

One is the public ledger for Congress that is required by law. Then there is a classified one that covers actual operations cost for all programs, including the top secret ones. Very few people ever get to see that one. And then there is, at least, one more, which is a planning budget that contains many future scenarios. I am sure that there is currently a lot of political wrestling about how those moneys will be raised in the coming years.

  4004.  @KeithAllpress  None of this has anything to do with quantum mechanics. You can derive the structure of quantum mechanics in a more or less trivial fashion from special relativity. You can actually do more than that. The standard model is basically just a product of three unitary representations of the Poincare group (OK, it's a little more complicated than that, but not by much). The only "mystery" is why it is this product and not some other. Theoretically nature could have chosen many other low energy effective field theories, but it didn't. All we have, right now, is an anthropic argument why it's this and not something else. That's kind of lame (we had such arguments since the 19th century for classical physics, already, so it's not even new).

  4005.  @KeithAllpress  The universe doesn't owe you travel between the stars in a human lifetime. It would also be highly unhealthy. Simulations of the early solar system suggest that there might have been a lot more planets in the early solar system, but many got either kicked out or they collided...neither of which is a good thing for life. That is exactly what keeps happening to stars in globular clusters today: they are gravitationally unstable. Technically even the solar system is probably unstable and the stability timescale of the sun and the planets alone is rather short, on the order of millions of years. This means that something has to be stabilizing the system. General relativity seems to help a little and so do gas, dust and small bodies. Personally I suspect that we would still be unstable without dark matter and I am looking at the stability of planetary systems as indirect evidence for dark matter fields, but that's probably awfully hard to validate with current observational data.

    1
  4056.  @nicholaslogan5185  Even with atoms it's at most wave mechanics and you are learning the wrong lesson if you are listening to the usual wave-particle duality nonsense that permeates the internet. The reason why atoms, neutrons, electrons, photons and buckyballs show similar wave-like behavior is because we aren't measuring either of those "things" in a geometric scattering experiment. We are measuring the behavior of the quantum equivalent of kinetic energy. Energy always behaves the same, no matter what kind of system exchanges it with an aperture. That is the correct explanation on the level of quantum mechanics. There is no such thing as collapse. What people falsely call collapse is an irreversible energy absorption process. The energy that was originally in the quantum field is now in an "external" system called "detector". So where do "waves" come from? They come from boundary conditions of linear equations. Because linear systems do not interact with themselves in the bulk (free space) the solutions on any part of their boundaries can only depend on the conditions on the remainder of the boundary. And because of homogeneity and isotropy the only relevant geometric quantities are the differences in distance between the boundary points. Guess what that leads to? It leads to EXACTLY the same quantitative behavior in the far field that you were taught in high school about the optical double slit! We don't even need light for this. The double slit works with water waves just fine... and for the exact same reason: small ripples on a liquid's surface are sufficiently linear and they don't interact with themselves. So you were, indeed, told everything there is to know about this system, even for atoms. What you were not taught is WHY the optical solution is universal. That requires a bit more abstraction than we are teaching at the high school level, but not much more. This is all physics and math undergrad material. The real step up to quantum mechanics, if you want, would be the realization that quantum mechanics is an ensemble theory. Ensembles are infinite repetitions of the same experiment, using the assumption that all individual copies are completely independent of all other copies. In that case we can apply Kolmogorov's axioms to the problem. You may have been told in high school that the solution to Kolmogorov is probability theory. That is true, but it's not the entire solution. One can, with a bit of juggling, find a solution that is based on scalar products in an abstract vector space and that solution is, if tailored to the requirements of relativistic physics what we call quantum mechanics.

Don't tell anybody, but Sabine doesn't know that time is that which the clocks show, either. :-)

  4072.  @GeorgesDupont-do8pe  Yes, we know exactly that time is that which the clocks show. We made the clocks and we defined the word "time" that way. The only problem here is that you and Sabine weren't paying attention in your early lives. ;-)

    1
  4074.  @GeorgesDupont-do8pe  The clock isn't wrong. The clock is the clock. You are simply looking at a delayed signal from the clock. The delay depends on your position and relative motion. So why is it important to know that time is that which the clocks show? Because a clock is, BY DEFINTION, a local energy reservoir that emits that energy in a controlled manner into the physical vacuum. The relativistic effects on clocks are therefor actually effects of spacetime on the flow of energy. See how much you can deduce just by knowing the basic definitions? ;-) I am a physics PhD, by the way. You are preaching to the wrong man. This was my profession. ;-)
    1
  4075.  @GeorgesDupont-do8pe  Literal? Physics doesn't run on allegories. It runs on comparisons. F=ma compares three phenomena, acceleration, inertia and force, and defines a strict relationship between them. The only way to truly measure a force is to let it act on a test mass and then to measure the acceleration of that mass. My high school physics teacher told me once that if a science teacher introduces force using a spring balance, then students will remember that for the rest of their lives as the definition of force: force is that which elongates a spring. That is a completely unworkable definition in physics. It's completely false, but that is what "sticks" in the layman's mind. The imagery of the spring is stronger than the words of the actual definition. This phenomenon of "learning the wrong lesson" is unfortunately fairly universal. I am trying to correct some of the misconceptions in people's minds (which is a fool's errand, I know) by giving them the correct definitions. Much of the ontology of physics is like lawyering: every single word and their relative position to each other matter. Not everybody is cut out to be a lawyer (I am not) and similarly not everybody can make peace with this property of physics. Not even the theorists (like Sabine), who are so focused on the math that they often forget what it means: behind every one of our formulas there is an experiment.

  4086. Consuming media does not fulfill psychological needs any more than getting drunk quenches thirst. For one thing, the characters somebody might get attached to do not even exist. One might be fascinated by the person an actor or an actress plays in a movie or a tv show, but that character is an invention. It does, if anything, resemble experiences of the writer and director more than it resembles that of the actor or actress. Even a meeting with either of these people will confront the fan with somebody who is completely different from the characters the artistic product creates. An easy psychological workaround would be to show the production of the movie/tv show in a series of outtakes that break the illusion. Seeing a scene repeated a dozen times with bored production staff standing around waiting for the shoot to wrap up will easily prevent any kind of "affection" that desperate people might feel for their idols. Let's show media production for what it is: hard work by a staff of dozens to thousands.

  4093.  @papalaz4444244  Schroedinger simply didn't get that quantum mechanics is not about objects. It's about energy exchange. Since energy is a system property it doesn't have a size. That's why QM is valid at any scale. It's not even true that quantum effects are not detectable at large scales. The Planck spectrum of the sun is quantum mechanics at work at the scale of a star. The photoelectric effect can be detected with a macroscopic piece of metal connected to a macroscopic mechanical electrometer. magnetism is a quantum effect. So is superconductivity. There are simply smart ways of thinking about nature and there are not so smart ways. Schroedinger's cat is one of the least smart ones.
    1
  4094.  @papalaz4444244  Schroedinger was obviously both educated and intelligent, but being smart about something is different. It translates into useful and working strategies of dealing with a problem. Schroedinger's approach does not satisfy those criteria. His argument doesn't address physical reality properly and it doesn't solve the issue of how quantum mechanics actually translates into the macroscopic world. He was too late, anyway. Both Heisenberg and Mott had solved it before him, already.

The question here is... do you really want to find out what happens if he decides to try it out? Last time he was president the US lost 1.2 million civilians. If the button comes into play, then 120 million will be a lucky lower estimate. It could be many more than that.
    1
  4110. Yep. You are 100% correct. It's no different from e.g. the motion of dice. Rolling dice are not in a superposition of 1 to 6. They simply don't have an outcome state until they come to rest. It's exactly the same with quantum systems.

  4115.  @Thomas-gk42  Intuitionist math is not even self consistent in mathematics and in physics it's just total nonsense at the kindergarten level. The statement "The red ball is in the box or the red ball is not in the box." is empirically true as long as there is a red ball and a box that it fits in. Dude, this is bullshit, plain and simple. :-)

  4120.  @AORD72  The point is that there is nothing "special" about the case of vanishing rest mass. Energy and momentum are perfectly well defined. All this worry about "what happens to photons" is unnecessary. Nothing special happens. There is simply no rest system without rest mass. That's all. One can still define coordinate systems and time perfectly fine with three and four independent plane waves. That's what GPS does.

  4123. No. It would probably not be a particularly good idea, either. It is likely that a nuclear explosion would be the outcome of such a device.
    1
  4124.  @Chaos3183  Because removing the mass from massive fields greatly alters their effective ranges and dynamics. If all fields were effectively massless, there would be no stable matter, as far as I know, which means that atoms and nuclei would disintegrate and release their binging energy. I am sure somebody already wrote a theory paper on the dependence of nuclear physics on the coupling to the Higgs. We just have to do a literature search.

  4137. Why do you expect me to have emotions towards a man who allowed his three children to hide behind three grandchildren? That is not how normal humans behave, so why do you expect me to feel for these people?

  4157.  @anywallsocket  Yes, that's why I called it bullshit. :-)
    1
  4158.  @anywallsocket  I am simply calling bullshit bullshit. All of you need to be reading up on the definition of science. It ain't the same as the definition of mathematics and it's definitely not the same as the definition of philosophy. Not even phrases like "hidden variables" belong into a discussion about physics and there are no "measurement choices" in physics. There are only people who don't know enough about physics. I suggest you read a few good books about quantum field theory, then you will understand what I am talking about.

  4171. Photons simply don't exist on paths. They are work that the source performs on the electromagnetic field and work that the electromagnetic field performs at the detector. That performed work is simply electromagnetic field energy as long as it's not being removed from the field... but energy does not have a location or a path. It is simply a system property of the field.

  4186. Mostly so that the average high school student doesn't commit suicide. Kids have a breaking point and most of them break when you ask them to digest material that is even hard on adults. Of course, if you want to torture kids in school even more, why don't you ask them to translate Homer's works from Greek into perfect English hexameter in third grade. I am sure you will find half a dozen third graders in the country who can. The rest will simply walk out on you mentally and they will start taking drugs to forget what grandiose failures they are. What do you think?

  4192. Meanwhile...worldwide EV sales are hitting 18% this year. They will be 20-25% next year and easily overtake ICE sales by end of the decade. Oil producers know this and they have to play a long game because of the investment in new fields. Their business model is literally going to dry up within the next two decades. The only way to extract money from the remaining oil in the ground is to sell it cheaply while they can. So why would the US not flood the world with the cheapest shale they can produce?

That's how such nonsensical statements come to pass.

Unless your kid learns these things, it is completely clueless of mathematics.

  4207. Yep. Physics in particular hasn't been materialist since the early 20th century. We know that "matter" is just an emergent effect. Sadly almost everybody is still wrapped up in the false philosophical categories of the 18th and 19th centuries. We had modern physics for almost 100 years now and very few people have even noticed that is it NOT an extension of 19th century physics. Quite the contrary. The reason for that is our school system. We are still teaching Newton, which is 100% false at the ontological level.

The only question is whether it will happen before or after a local nuclear war with hundreds of millions of victims.

  4273. That scenerio does not have time reversal symmetry because a single starting point can have an infinite number of endpoints but none of those endpoints will ever lead back to the starting point.
    1
  4274.  @kreynolds1123  Time reversal symmetry is simply dynamically broken. There is nothing particularly strange about that. Eggs that broke after falling on the floor don't rearrange themselves and they don't jump back onto the fridge shelf.
    1
  4275.  @kreynolds1123  Yes, they do. It's all a consequence of state space volume. Technically it's not even restricted to state space. I am not a mathematician but I suspect that it's true for all topologically ordered sets that have more than one effective dimension. There is almost always more "over there" than there is "right here".

Hezbollah is too cowardly to even try, even as its leadership is being dismantled by Israel. The rocket attack on Israel failed. Saudi Arabia has begun to fund its own nuclear weapons program with tens of billions of dollars. The future for Iran looks very grim, indeed.

    1
  4321.  @malvoliosf  The timing? I have no idea what that even means. How long things should take? That's an immature kid talking about his demands for how long it should take for the cookies to bake. Please. As far as you can tell? That only means you don't know anything about the diversity of the field. Fail. The market? For a science experiment? There are no markets for science experiments. Why not you? Because you are a fool. Next!

  4328.  @Alkis05  If there are lots of such examples, then you will be so kind to make a list for us with proper scientific citations. Thank you for your intellectual honesty. What's the urgency, anyway? It's not like the universe is a fleeting phenomenon. It will still be here a hundred years from now and it will look exactly the same. :-)
    1
  4329. Microsoft is still selling the same OS and the same office tools as 30 years ago. Google is still an advertising company and Jeff Bezos is still a glorified Sears Catalog distributor with larger warehouses. Do you know why? Not because these guys are stupid. It's because there are only so many product and service categories that every human being on the planet needs. Look up the total worldwide market for violins. Will it surprise you if I said that Apple makes more money in half a day than all the people together who are making violins? Probably not. How many violins does the average person buy each year? THAT is the problem. ;-)

  4330. There are no particles. You are welcome.
    1
  4331.  @likesunshineafterrain2298  Yes, it does. Once you realize that quanta are not "stuff" but merely small amounts of energy that quantum fields exchange with other systems, then quantum mechanics turns from weird to completely natural.

  4334.  @nunyabiznez6381  The worldwide broadcasts of the wedding and coronation of Queen Elizbeth II were considered scandalous by many. Traditionally royal weddings and coronations were reserved to royalty. There were no Kings of England before the 10th century, so the entire show is, at most, 1100 year old. One could argue that by the early 18th century the monarchy had become a puppet theatre, so there were no more than approx. 800 years of real English Kings and Queens.
    1
  4335.  @nunyabiznez6381  See how much time you are wasting on some silly old people? How productive is that? In the time you are talking about royal blood Elon Musk launches a new car production line and a rocket to the moon. :-)

  4336.  @Ryan-gx4ce  It doesn't even work in theory. When the concept was developed computers had very little memory (32kWords or so) and software was necessarily small and simple. The academic examples on which inheritance was demonstrated in the early days are nowhere close to the kinds of systems in which it is in use today. That it would have to scale was therefor not a concern of its inventors.

  4337. China isn't adapting well. You can clearly see this in the absolute dictatorship strategies of Xi. The Chinese are rudderless and are trying strategies that have never worked in the entire history of mankind.

  4338. There are sometimes very good reasons not to use the standard libraries. The standard C string library, for instance, does not appear to be safe on some bare metal environments that are using interrupts and require re-entrancy. I can't tell you why I got errors once, but I can tell you that my own primitive loop implementations didn't produce that problem. I don't know whether it was a library or a compiler issue, but it was reproducible. I didn't care about reading the sources of stdlib and string because I wasn't going to "fix" the problem that way (who wants to work with a forked stdlib or string anyway, right???). I simply worked around it, albeit with a slight performance hit, and the result has 100% uptime and no known bugs. Just because it's old and time-tested doesn't mean that it always works. Caveat emptor, as they say... even on things that should work just fine.
    1
  4339.  @HealthyDev  There are extremely few pieces of software that are nearly perfectly debugged. I would say that maybe the block device related libraries are the best examples for a non-trivial piece of software the one should not touch. I can not, for the life of me, imagine that I could write a better (S)ATA library than the ones that have been deployed literally billions (trillions?) of times in hard drives. That's about as good as it gets. Beyond that it's free range for me. I usually write my own schedulers, for instance, because there is no "one size fits all" for that piece of code. It depends so much on the hardware and the (real time) problem that one has to allow for the re-invention of the wheel.

  4363. OOP is bad. Really bad. There is no need to defend it. It is so bad that your statement that one can write good OOP code by following (a sufficiently large number of) design patterns is absolutely untrue. But that doesn't make FP good. FP is just as bad as OOP in many respects and much worse in some. It doesn't solve any of the hard problems of software design but it does so (or does not) very inefficiently. If OOP has something going for it it's that it doesn't introduce runtime overhead (it just makes the compiler work hard to remove all of it during the compilation cycle). FP, however, does introduce both memory and runtime penalties. It also stops people from thinking about what it is that they really need to do... and that is the really harmful side effect of these paradigms: they pretend to be a solution, which seems to remove the need to think hard about actual solutions. ;-)
    1
  4364.  @hrtmtbrng5968  It is not good engineering to add overhead where none is necessary. All the touted advantages of these paradigms are more or less about how they prevent people from writing "bad code". That's basically just the "GOTO is evil!" battle cry of those who don't understand that all compilers generate nothing but GOTOs... they are called JMP instructions. That's the only language CPUs speak. In reality poor code can't be solved with language features or programming paradigms. It originates in the minds of poorly educated programmers and that is where it has to be stopped - with education. Many more people are telling you that a first century AD zombie called Jesus will come back and resurrect us all etc.. "Many people will tell you" is bullshit that tries really hard to avoid actual analytic work. Dijkstra and Knuth simply knew that all Turing complete languages are equivalent. So what does language design do for you? It's a psychological tool to shape your thinking about problems. Is that a good thing? No. Why? Because it builds a bias into your mind for what the "right" solution is. That's not good engineering. Good engineering is focused on the problem, not on biasing the mind of the problem solver.

  4365.  @diamondenchantmentx  The people who wrote the OT had no interest in the question "Where it all came from...?". They only had an interest in "Who is protecting us?". The OT is a political text in which religion is used to cause a cohesive tribal identity for the Jewish people. They key phrase is not "In the beginning... ", but "I am your god who brought you out of Egypt..." because the Jewish god differentiates the Jews from the Babylonians who believed in the Babylonian gods. The discussion about the scientific credibility of the Genesis account did not even exist until the 17th century, or so. It's a modern phenomenon that developed after the reformation.

  4373. ​ @AgentSmith911 If Ukraine can trade ten percent of its population for its freedom then it will. So that's on the order of 4 million people. I kind of doubt that the Russian people are interested in giving that many lives or more for the conquest of what will be a mine-infested moonscape by the time they reach the Polish border... at which time they will be fighting with all of NATO and incur the next 40 million deaths. ;-) ​

  4374. The observer's quantum state doesn't become entangled, either. Entanglement is a reversible phenomenon. Observations are irreversible. People who are barking up the entanglement tree understand neither entanglement nor observation, even though the difference is absolutely trivial.

  4378.  @57Cell  An inclined plane ending in an infinite flat is dynamically irreversible. Once you let go of a ball on the inclined plane it will pick up velocity until it reaches the flat part and then keep rolling to infinity. Dude, I can't help it that you are clueless about physics. You simply didn't pay attention in high school. :-)

  4379. Testing doesn't buy us much unless it is systematic and there are enforced quarantine rules for those who test positive. By the time people test positive because they had symptoms they have usually been vectors for up to several days, already. This was clear since the beginning of the pandemic in 2020, but the lack of other measures kept the public too focused on testing. ICU admissions down are great, but ICU services are a tiny percentage of all healthcare services. As long as hospitals are stressed they can't perform timely elective procedures and that is very bad for public health.

  4385. Angular momentum can be conserved among any number of quanta. The consequences for the outcomes are just getting weaker and weaker as we are increasing the size of the system. Maximal entanglement happens between two quanta. That's why statements like "black holes are entangled with the remainder of the universe" are such intellectual nonsense. Your cup of coffee is entangled with the remainder of the universe. So what? So basically nothing. The consequences of that are essentially non-existent, unless you are stupid enough to fling your cup of coffee around real quick and hot liquid splashes into somebody's face.

  4396. Currently it's not even that. A hypothesis has to be testable. String theory is simply to general relativity what quantum field theory is to special relativity. It's a necessary piece of mathematical machinery that, unfortunately, didn't manage to tame the QFT landscape. It just replaced it with something of similar size. The great hope that gravity might restrict the universe to this one and no other has, so far, not materialized.

It will end with even more dead Palestinians and even higher walls, like always. The Israelis aren't going to learn from it, the Palestinians aren't going to learn from it and Iran will simply try to rinse and repeat. There might be some more or less spectacular retaliation in Iran by Mossad. We shall see if the Israelis have some plans for that. Will anything change for the better? No. That piece of land has been poisoning the hearts and minds for thousands of years and it won't stop doing that.

  4413.  @kevinbyrne4538  Dude, resistance means that you can't become a vector, so if omicron can effectively infect you, then you are not resistant by definition of the word. Seriously. Let's get at least the language right. 🙂 In any case, we have omicron infection statistics. Unvaccinated adults were five times more likely to become vectors than vaccinated and boosted adults. The discrepancies for hospitalization and deaths were even larger. COVID-19 has now become a disease of the unvaccinated. The unvaccinated are filthy and stupid people, indeed. :-)

  4415. That, unfortunately, is a misrepresentation of physics. Random variables do not conserve energy, momentum, angular momentum and charge, hence there can be no random variables in nature. What we see is entanglement between local measurements and systems to which we don't have access. That lack of knowledge is not the same as actual randomness.
    1
  4416. @ No, we didn't. True randomness means complete independence of everything else. That's an abstract assumption that is simply not true in nature. There are no random properties. There can be no random properties. The real problem isn't that, though. The real problem is that people have been falsely taught to treat randomness as the opposite of determinism. That, however, is a false dichotomy pair.

That's just the nature of the human beast. I am sure she got started out on the right side of things, but in order to create following and hits she had to pass over... and she did.

  4430.  @fermansmith6042  She is "different" from other physicists? How many physicists do you know? I mean, real ones that are working in labs and theory departments every day? Not the ones that are selling books on YouTube. The most special thing about her is that she takes cheap shots at her own profession on YouTube. She is perfectly allowed to do that. Physicists are big boys, we can stand up for ourselves and trust me, she isn't moving even one cent of science funding one way or the other with these public comments. That's not how this works. Look, this is entertainment. It's here to titillate. As long as you don't think that you are being taught something real about physics and science in general, it's all good.
    1
  4431.  @fermansmith6042  I am a PhD, but it doesn't matter. Physics, science in general, is probably best compared to an apprenticeship. It's not just the theoretical knowledge that you are being taught in classes. It's the work on a variety of problems, usually collaboratively in small and large groups, that make you "a scientist". It's the (lifelong) learning from others in your field. That's no different from being a goldsmith or an NFL player or any other kind of specialized professional. Either you can make pretty jewelry or play the game or you can't. One can not really communicate that to others. Even the lingo is subtle and different enough from "normal language" that communication with people who are not familiar with it is limited. The physics community has its own sets of concepts about reality that can not even be found in other sciences. I know about a dozen active scientists from other fields who are utterly flustered by the way physicists "think" about the world. I tried explaining some in person... with little success. Well, neither do I understand how a chemist can figure out a 40 step reaction without ending up with useless chemical "mush". They can. I can't. I can do my stuff, which they can't. That's why we have different job descriptions. This is not to say that physics is something special. You can find this phenomenon also among musicians, authors and artists. Ask someone how they compose a serious piece of music and you will get a bunch of textbook answers which will do absolutely nothing for you to replicate that achievement. You won't even be able to write a simple melody that way. Human experiences are unique that way and physics is one of these experiences. If you want it, then you have to live it. Peace!

A seasoned professional will never use char, int, long etc. but always explicitly declare the length of these variables.

Just like I can't prohibit you from believing in the virgin birth I also can't stop you from programming your computer any which way you like AS LONG AS NOBODY GETS HURT. I can, however, punish you if somebody does get hurt. That's why doxxying should carry a minimum mandatory sentence of two years without parole, for instance. That would get rid of that problem almost completely. Similar sentences should be given to people who hurt other people using AI. Let's say you make that 2 years without parole for every person that gets hurt by an act caused by an AI that you own, companies would be extremely cautious to unleash it on the public.

  4506. We have tried and theoretically analyzed many different forms of democracy. All of them are suffering from one kind of problem or another. The real issue here is not the organization of democratic systems but the average intellect of the voters, which is just too low to make it work well. One can not raise the IQ of the population by making institutional changes. One could, theoretically, implement meritocracies where people of higher (proven) intelligence get to have a larger political impact, but that itself is going to lead to corruption very soon as intelligence does not preclude people from selling their influence to the highest bidder.

  4507.  @colby25 The Italians have tried it with a dozen parties. That didn't work well as you may imagine. Germany had a three and then four and now five party system for decades. It still hasn't solved issues that have been on the table since the 1970s or earlier. I think both Brexit and Trump have proven beyond doubt that it's not the system... it's just the stupidity of over half the population that causes the problems. There might be one productive thing that one could do: age limits for voters. It's kind of pointless to have 80 year old people voting who won't be around to reap the fruits or bear the brunt of their decisions. Voting should be limited to those who have an actual long term stake in the fallout of their political vote.

  4508.  @flybefree  Ranked choice doesn't help if a majority of people would still be voting Trump. What you would see is that the left would fracture and the right would gather around a strongman, even if he would get only 30% of the first vote. If respect was of any value to the current voter, then Trump would be sent packing with 1% of the primary votes. The truth is that not even Ronald Reagan would be electable by today's GOP primary. I agree that the super PACs are a bad idea.. but the current supreme court thinks they are covered by free speech, so we are not going to get rid of them anytime soon. The filibuster has actually saved the day more often recently than it has ruined it. But, again, these are tools. What counts is the mindset of those using them. You have to remember that even Hitler was democratically elected and Putin had real majorities in the past. Democracies don't protect themselves if the people don't protect them.

Inflation makes sure that most of it will never be paid back. Investing in national debt is either a foolish investment or it's a risk mitigation tool. I suspect that's why banks are buying it. That doesn't mean they will be paid back. It just means they have a 100% safe investment base for their federal audits. ;-)

Even the drone war right now is primitive. In ten years all drones will be loitering ammunitions that will find a human being using infrared seekers. The ratio will be almost one drone for every one KIA or WIA.

  4544.  @rememberallah5201  It doesn't look like the antibody counts lie. After infection and vaccination the body produces the most antibodies and they decline slowly over the following months. Antibodies are our first and fastest defense. They neutralize the spike protein that the virus needs and they cause the initial immune reaction. The T-cell responses are much slower in comparison and they are not as effective in preventing the virus from multiplying quickly. People with multiple infections and people who had VOCID after vaccination are living proof that there is no case to be made for lasting immunity. It is unfortunately also true that not everybody has the same immune repertoire and we don't all make the same antibodies and equal numbers of them. There is a wide range of immune responses and that is one of the reasons why some people get more sick than others. Since the virus mutates even those who didn't get (very) sick the first time don't have automatic protection for the future. This is, whether we like it or not, a biological roulette. Some win, some lose, and nature doesn't care because evolution only works if there is a stochastic component. So, yeah, this makes life risky and the best you can do is to minimize your risk. It will, unfortunately, never be zero.

  4546.  @rememberallah5201  I don't remember anybody telling you to take a vaccine every 3-4 months. We told you to take two shots a month apart and one shot with a lower concentration of the vaccines at least six months later. I don't even know how I could get another shot even if I wanted one. My doctor would certainly not give me one and neither would my pharmacy. So what, exactly, are you talking about? I am not aware of a firm date for the availability of the next vaccines, but I would not expect them before Q3, which means it would take at least until Q1 2023 for widespread uptake. That's closer to a year and a half since the last booster. So where does your 3-4 month bullshit come from, exactly? I had at least 50 vaccines in my life, probably more. My immune system is fine. I had flu shots every year for the past 15 years and those were the only years of my life that I didn't catch the flu. Look, your fears may be real, but they are not rational.

  4547. Photons don't pass these filters, at all. A photon is a small amount of energy that an external system emits into or absorbs from the electromagnetic field. So if the filter does not absorb any energy, then there is no photon to speak about. If it does absorb a photon's worth of energy, then that energy is gone from the field, i.e. it does not "go through". Part of the problem with quantum mechanics is that most explanations do not contain this aspect of quanta but they treat them as if they were classical objects, which exist independently of their detection. That, however, is not what quanta are.

  4560. @ They have been teaching the photoelectric effect in Germany for over 40, if not over 50 years. That is exactly how quantum mechanics works. It simply a specialized example of the general scheme. It tells you that photons are quanta of energy. Where in that experiment do you see particles? Nowhere. It's a macroscopic experiment which is usually carried out with photon numbers on the order of 10^12-10^15 or so. Where else have you seen something infinitely small? And how did you do that? I am an experimental high energy physicist and I have never seen a single particle in my life. What I have seen by the trillions were irreversible energy exchanges between the physical vacuum and the matter of my detectors. The difference between an atom and a quantum is fairly trivial: an atom is a persistent object that can be observed many times. A quantum only "exists" exactly once: as the amount of energy that flows between two systems during an emission or an absorption event. Easy, right? I would almost call the difference between "many times" and "exactly once" kindergarten level physics. No, not so easy at all, actually. It is this seemingly trivial difference that makes it so hard to get used to quantum mechanics because it has enormous consequences. It does, for instance, not allow us to assign "paths" to quanta. Yes, you will have to start over with everything you believe you know because NONE of it is as you think. That is not my problem. It's yours. You have to forget everything about atomism because quantum mechanics is NOT atomism. It's pretty much the opposite of atomism. Oh, and you will have to learn special relativity, because quantum mechanics is a direct consequence of it. If you have never heard that before, then you are in for quite a shock. There is no version of quantum mechanics that can be understood without it. ;-)

  4570.  @motivationmonster596  Electromagnetism isn't easy. It is not intuitive IMHO, not even for a classical field theory. It is certainly far too complex for high school science, but we still want people to have some understanding of electricity, which means that we have to reduce the physical reality to concepts like electrons flowing in wires. That, by the way, is not wrong, if we are interested in things like electrolysis. There we really have to count moles of electrons moving in wires. It's also not entirely wrong for static electric and magnetic fields. When it comes to dynamic fields, however, the motion of charge carriers becomes a secondary phenomenon and the motion of electromagnetic fields is best explained in the context of special relativity... which, of course, is beyond the high school level for sure.

  4573.  @2adamast  Yes, you are living in the world of middle school science. In the world of PhD level physics all energy flows through the vacuum and electrons in metals are merely boundary conditions that determine what those fields look like. Look, physics can be complicated and electromagnetism is where things are transitioning from classical physics (stuff moves) to field theory (energy gets transferred by configurations of the physical vacuum). It's nobody's fault that we can't teach this properly at the middle school or even at the high school level. It's conceptually and mathematically simply too involved. It is actually so complex that even many EEs who are tasked with developing high speed electronic circuits are having difficulties with it.
    1
  4574.  @2adamast  I don't remember saying anything else. Neither will a cable pulser. Having said that, your "event horizon" argument, while valid, gives you only a limit and it's not a precise estimate because of the dielectrics, which slow things down. It doesn't tell you anything about waveforms, either. Transmission line theory does.
    1
  4575.  @marijnvangeest  I believe I said that we don't need moving charges for energy flow, not that either the classical theory or the quantum theory is complete without them. Both theory and experiment support that notion. What moving charges do here (and that is their only function in energy transmission) is to direct the energy to where we want it. Trust me, your power company would be more than glad to get away without having to lay thousands of kilometers of very expensive wires to get the energy to you, especially since they cause losses. As you can see in the night sky, the physical vacuum is (in a sense) completely lossless for electromagnetic radiation. It gets to us all the way from the end (i.e. the beginning) of the cosmos. :-)

  4614.  @kusha010  One has to get used to the idea that in modern physics system properties come before matter. It is a very different way of thinking about the world. Call it an acquired taste, if you like, or an effort in "unlearning". It certainly didn't come easy to me. You are correct that energy and momentum exchange can have the same effect on you as a stone that is being thrown at you. That's what makes it hard for us to let go of the "particle" fantasy. On the surface the exchange of these properties looks very much like the exchange of bits of matter. Back in the 18th and 19th centuries they were using the concept of the "phlogiston", a mythical material carrier of heat energy, for exactly that purpose. It turned out to be a scientific dead end and we eventually accepted that heat is microscopic kinetic energy. The problem with localizing energy and momentum in particles is that they don't behave the same way at the microscopic level as quanta do. A free quantum of energy can be anywhere, while a particle has to be somewhere. The observations of the behavior of energy transfer do not agree with the expectations of material particle behavior. The mathematical difference is somewhat subtle. A free quantum behaves like a member of an unmeasured quantum mechanical ensemble (a plane wave), while an actual particle behaves like a sequence of measurements that are connected by conditional probabilities. It shows a random walk behavior around a classical path. We are doing a very poor job in physics education to teach the difference between unconditional and conditional probabilities.

What he didn't know was what consequences that answer had for classical mechanics and why it made more sense to abandon classical mechanics than electrodynamics. That all physics was relative was, by the way, already known to Galileo. He pre-empted Einstein's elevator Gedanken-experiment with a similar but logically equivalent example of the physics inside of a moving ship by two and a half centuries. What he didn't know and what not even Newton and his successors realized is that the principle of relativity, when applied to coordinate systems, has two algebraic solutions. One solution are the Galileo transformations, the other the Lorentz transformations. Anybody with sufficient algebraic knowledge (that's basically every mathematician since roughly Euler or so) could have taken relativity as a principle and they could have scribbled down the derivation of the Lorentz transformations in less than one page of high school algebra. That nobody did is one of the great mysteries of physics and mathematics, IMHO.

By all our experience the future is open and for the most part unpredictable. That's in contrast to the past which has already happened and which is unchangeable. This is kindergarten material. :-) The only non-trivial thing about all of this is that there is a third category of spacetime event/volume that is "neither". What is happening on Mars, right now, is neither in our past nor our future. It is completely outside of our access.

  4677. You are correct. If you think that coding is too difficult, then you should better get a real job... like mailman. ;-)

  4678. Solving a problem faster is only useful if the result is correct. Let's say your AI creates 8Gbytes of code in 3 seconds. Now you have 8GBytes that are most likely garbage. How are you going to test that code to make sure that it's correct?
    1
  4679. @ All I am saying is that generating more code faster doesn't solve the problem. Truthfully, most code doesn't solve any problems that couldn't be solved without any code at all. A hundred odd years ago Sears-Roebuck was doing exactly the same that Amazon is doing today. And I mean EXACTLY the same. They gave customers a printed catalog in the mail, customers filled out a form and mailed it back to Sears. Sears packed all the items into boxes in one of their warehouses and then those boxes got delivered to the customer. What's the difference between back then and today? 24-72 hour delivery compared do 4-6 week delivery. That's it. Nothing more, nothing less. What does Netflix do? The same as Blockbuster and movie theatres used to do and terrestrial and then cable tv providers... they deliver multimedia content. In all of these cases customer satisfaction only depends on one metric: that the merchandise arrives in good condition in a reasonable amount of time (what is considered reasonable has changed over time) at the customer's destination (which in case of multimedia used to be the local movie theatre until tv took over). What happens "in the code" is entirely irrelevant, to the customer AND to your big boss. The code may even have huge flaws as long as the customer doesn't notice because the organization compensates. That's why this entire "formal proving of requirements" thing is ridiculously impractical. It does NOTHING to solve the actual requirement: customer satisfaction.

  4682. Not all corporations work the same way. You can't just read "Corporate dysfunction for Dummies" once and be safe for your entire career. The most important question for YOU is whether your fellow employees and bosses are working for the corporation (in which case they will give you support) or for themselves (in which case they will sabotage you). I have experienced both environments and there is absolutely NOTHING that you can do in the latter case except to leave. That boat won't be sinking without you, but why do you want to be in a boat with backstabbers? OTOH I had a very pleasant experience in a smaller company once where everybody was like family and we all helped each other out. It was actually fun to take a break from my own problems and to help the guys next door to debug theirs.

  4686. But why do it in 90 minutes if you can do it 25 with the same system?
    1
  4687.  @Treblaine  The system is not competing against airlines. It's a unique solution that it better, not just equivalent to planes for the 100-1000km range. I don't quite understand the security issue here. I have ridden trains for much of my adult life. Terrorist attacks on trains have been carried out periodically, even in Europe and Japan, but we never implemented any sort of cargo checks. Why is this supposed to be a problem for hyperloop when it never was one for low speed and high speed trains???? Are we exercising a double standard here or what? In any case, you don't need any cargo on a 25 minute ride. You don't even need your handbag. It can ride in a cargo pod that leaves a few minutes before the passenger pod. I don't believe you are thinking straight here. If anything, this system can solve the security issue much better than other systems, including aviation, that puts cargo on the same plane as passengers.
    1
  4688.  @Treblaine  A bomb on a regular train also has the ability to kill everyone in the car, and such incidents have happened. Yet we are allowed to carry a 50kg piece of luggage onto these trains without any checks. You and other critics aren't making any sense here. Hyperloop security is easy: absolutely no luggage in the passenger pod. One and done.
    1
  4689.  @Treblaine  You aren't making any sense just now about the terrorism threat. Please get yourselves better arguments. :-) A small hole in a pod will leak a small amount of air. The oxygen masks will deploy, like on every plane. The pod will be slowed down and the tube will be flooded within a minute. You still aren't making any sense.
    1
  4690.  @Treblaine  Dude: pay attention to my words: the entire tube would be filled with air after a minute in case of an accident.
    1
  4691.  @Treblaine It's impractical because you say so? That's exactly what they said about the horse. :-) In any case, my electric leaf blower disagrees. It can fill up ten cubic meters of volume in less than a minute. In other words... the inrushing air to refill the tube is the equivalent of one electric leaf blower every meter, or so. Next you are going to say that a half inch thick steel tube will explode if a leaf blower blows into it, right? :-)
    1
  4692.  @Treblaine  Nobody has died from the air coming out of a leaf blower, yet, kid. :-)
    1
  4693.  @Treblaine  Tell you what, kid. You can buy a cheap vacuum pump and vacuum chambers up to 15 gallons on Amazon. That's approx. one two hundredths of the volume of one meter of hyperloop tube. Modify it so that you can let the air back in in a fraction of a second. Watch and learn how little happens inside the chamber when you do that. That's roughly what will happen if you refill the hyperloop tube in one minute. Take care. :-)
    1
  4694.  @Treblaine  The cheap Chinese vacuum pump that I got makes about the level of pressure that hyperloop uses. You are obviously scared to do the hands on research yourself. :-)
    1
  4695.  @Treblaine  So what you are really telling me is that you can't be bothered to evacuate a turkey fryer pot with a $75 vacuum pump to prove yourself right and you don't know how to scale experiments. Well, in that case, I am afraid, you will have to wait for someone to build the hyperloop to demonstrate that the DK effect was strong in you. :-)

  4701.  @Treblaine  I am repackaging matched bipolar transistors (five cents a piece) on aluminum core PCBs for improved thermal stability. The vacuum pump is needed to get a bubble-free epoxy potting around the module. Audiophiles are crazy for stuff like that and will pay tens of dollars per package. :-)

  4702.  @Treblaine  I am selling components that are roughly equivalent to ones that you could buy from Analog Devices a long time ago and that were typically used in precision analog circuits for military use (like analog computers in missile guidance systems). Of course all of this is completely obsolete technologically, but it has its lovers and where there is love, there is money to be made. Do I agree with you that it's a snake oil niche? Absolutely. But why should an old man not improve his retirement income with an easy to make product for which there is demand and which no semiconductor company wants to make any longer? 🙂

    1
  4708.  @aeebeecee3737  Let's put it this way... non-contiguous implementations of non-sparse arrays on machines without MMU (involvement) are a really, really bad idea, from a performance point of view. If you are looking at an array only as an access interface, then the implementation doesn't matter, of course. Few software developers have the option so say "performance is irrelevant".

  4711.  @benjalucian1515  Not even the texts of the NT were written by what we would call Christians, today. You may call them proto-Christians or early Christians, if you like, but their world was very different from ours. Their economic, social, political and emotional needs were very different from ours. If you met one of these people, today, you would, most likely, find that you have little in common with them. You may actually discover that you would agree far more often with a Roman intellectual like Seneca who was later adopted by Christians, which tells you that Christianity in many aspects is just a copy of the thinking of greater minds that would not wanted to have anything to do with its eschatological nonsense.

The misunderstanding of the nature of the photon is not such a deliberate teaching tool. It's just a very widespread mistake.

Let me know when your electricity provider is done installing the new power lines. :-)

  4729. That's not the problem with FP. The problem is that print() is a function with side effects. EVERY function that is actually useful in real life is a function with side effects. FP pretends that side effects can not be avoided, which is a trivial fallacy. Keeping state, for instance, which is the most important part of every program, is a side effect.

  4731. The basic problem of high energy physics can be summed up in a few words: We are trying to measure the spectrum of the physical vacuum. Atomic physics measures the spectra of atoms. Nuclear physics measures the spectra of nuclei. In a sense even gravitational physics is trying to measure the spectra of gravitating systems now (see LIGO and gravitational waves). The top level questions are not all that hard, but you are right: the details are awfully confusing. A relevant paper enables other people to make significant progress in a field and it opens up new ways of thinking about old problems.

  4734.  @omasbioladen3459  It's a tool like everything else. If I told you that everything can be solved with state machines, I would be lying, right? If I told you that messaging is the gold standard, I would by lying. Every engineering strategy, pattern etc. has a use case where it works like a charm. Ideally a software engineer knows as many of these strategies as possible. IMHO the main problem with OOP Is that it is restricting. Instead of opening the problem up to using the right solution strategy for every sub-problem, it is restricting the entire design globally to exactly one. Beware of false religions.

  4754.  @kurtiserikson7334  Science didn't talk about amoebas before they had been seen in a microscope. It knew about diseases that were caused by them, but nobody speculated that there is such a thing as a floppy single cellular creature that nobody had ever seen. The reason why a physicist does not have to speculate about the existence of particles is trivial, by the way. We KNOW what we are detecting in these experiments: it's energy, momentum, angular momentum and charges. Why these? Because these are the only properties that nature conserves between systems, at least locally. So why would we need to talk about particles? They are both unseen and completely unnecessary. Just like Hogwarts. :-)

  4760. What do you mean by "that composes matter"? Matter is a phenomenon that lives in an energy range between, at least, 1e-6eV (electronic fine structure, spin-spin interaction etc.) to 10^11 eV (nuclei) at the atomic level alone. One can extend that downwards and upwards by many orders of magnitudes if we take solid state effects into account. So depending on how you want to look at it, the "frequency range" of matter spans between 17 and maybe fifty or more orders of magnitude.

Personally I have come to the conclusion that we have entered another age of irrational politics similar to that before WW I. No matter where you look, Trump, Johnson, Putin, Xi, it's all men of questionable mental capacity. Putin used to be the most rational but something broke in the man. Maybe he got exposed to too much sun while riding bare chested. Xi is a Chinese career politician who only knows one thing: how to rise through the ranks. He never had a real program and Boris Johnson was always an empty gas bag on any level. He was mostly propelled by his hair, which is far superior to that of Theresa May. Trump, on the other hand, just proved that the fear of the Founders was well supported: the voter can not be trusted.

That may buy AI (or its user) a copyright infringement lawsuit, but it for sure won't assure a place in the Metropolitan Museum of Modern Art. I have yet to see successful examples of genuinely new artistic expression. The same is true for intellectual thought, by the way. The more you know, the more you have to unlearn before you can think about something in a truly novel way. Just heaping tons of information on a pile and hoping that sifting through that pile will result in something truly novel doesn't work. What can work is evolution, but evolution means that we need to have a death match of AI agents. Even that is difficult because evolution has a tendency to specialize for a niche rather than to develop a more general, more universal agent.

  4833. No offense, but it's simply not true that there is not enough supply of sex work. The demand is not nearly as high as the demand for pornography suggests. For one thing it's expensive, but for another it's far more demeaning to the buyer than to the sex worker. The buyer has to admit that he can not find a partner who is willing to supply a modicum of sexual gratification in a relationship. As far as legality is concerned, production and distribution of pornographic material are perfectly legal in the US as long a certain legal standards (like the minimum age for performers and all applicable labor and safety regulations) are met. The term "obscenity" does not prevent either the production or distribution of most of this material. It is reserved for what is outside of community standards... which are necessarily getting more and more accustomed to ever more extreme acts. A puritan mindset will not solve whatever problems this creates. We have tried that for centuries and it didn't do a thing. It's about as useless as the "war on drugs".

  4859.  @freedombug11  Yes, I did. If you don't know what the difference is between my folks getting it twice in 18 months (rapidly declining antibody count and viral evolution) and three times (the same plus the fact the she works with pre-school children, i.e. without any effective social distancing), then any data is lost on you. Of course infection is great for the initial two months for the same virus. The problem is that a year from now your antibody count will be low and the virus will have mutated... which is exactly the reason why you were always getting the flu and the common cold again and again and again. Please, folks, you need to think about these things.

When was there ever long lasting immunity against the flu or the common cold???? People are buying into religious interpretations of very fresh data here. Yes, my relatives didn't get re-infected after two months, either. There were up to eighteen months, or so, between the first and the last infections. So do you have great immunity for two months? Absolutely. After a year? Not so much. Not with the vaccines and not with a primary infection by the virus. And THAT is the problem.
    1
  4862.  @freedombug11  Dude, not to take a vaccine that offers excellent protection is plain stupid. There is no other way to say this, OK? Why did I say filthy? Because you don't get a disease by looking at an infected person on the internet. You have to be close and that is a choice. Social distancing works. The Chinese have proven that one can eradicate the disease with social distancing in twelve weeks. I bet it can be done in four to six, as long as everybody is willing to stay 20 feet away from everybody else. Yes, it is that simple. Would you like an STD with that? Can you guess how that works? Not by looking, kid. :-)

  4863.  @freedombug11  My relatives wouldn't know anything about that "better immunity" thing, my friend. They were sick two and three times now. So maybe all of this is true in your universe, it's certainly not true in theirs and mine. I am vaccinated and boosted and I didn't get sick even once. Neither did any of the other people I know who did the same, less one. Guess what he is? A medical doctor. He got it at work from a patient. Yes, I am pejorative because the problem here are NOT the people who are vaccinated and who socially distance. It's the people who are doing nether. Dumb and filthy is a pejorative way of saying just that. It's by design because that is how I think about people who can't learn, nay, who do not want to learn. As an educated person who has gone out of his way to protect myself and others I had it with the dumb and filthy. Excuse my language.

I think we made a huge PR mistake by not educating the public that vaccinations' main purpose is to disrupt the spread of the disease. It's not just about keeping infected individuals out of the ICU. As a consequence we did not effectively disrupt COVID-19.

The plane seems to be going insanely fast even after ground contact and it does not seem to be slowing down significantly, which is hard to understand given the enormous amount of friction that should be at work without the landing gear. One would expect the pilots to use every single inch of the runway... but the plane seems to be touching down rather far along the runway. I also wonder if they could have gotten rid of thousands of lbs. of fuel before landing? Was this plane still filled with lots of extra fuel?

  4896.  @WhiteDeVil3  You don't need a CS degree to be worth something. You need a CS education to know what you are doing with a computer, though. Coding and software ENGINEERING are not the same thing. Coding is a tool to support whatever else you are actually doing as a single person. As a physicist I code to get my physics problems solved. As a chemical engineer I code to automate my lab processes etc. But being a software engineer is a profession in which you are expected to get much more complex jobs done on time and on budget while working in large teams. There are a couple more levels to this. The first one is maturity. Almost everybody who thinks that they don't need help with learning is full of it and not nearly mature enough to be a good employee. Yes, there are people who can learn absolutely everything well on their own, but that they are so rare that you are guaranteed not to be one of them. If you don't know this, then you are definitely not mature enough for any job. The second one is time. A four year degree gives you four years of time to fail, and then fail again and to keep learning while you keep failing. A PhD gives you eight to ten years. Those are years during which you acquire the very experience that you are talking about. Does an employer want to give you four years of education in failing while you are learning on the job? Of course not. They want you to have all of that out of your system by the time you show up for your job.

  4931.  @lukask.181  Even in computer science we aren't intuitionistic. The halt problem, for instance, only claims (and its proof proves) that there are programs that can not be proven to stop after a finite number of steps. It's not a constructive proof which programs do not stop. The set of programs that stop is not a constructive set and neither is the set of programs that don't stop. The entire program of intuitionistic mathematics is therefor a folly. It is internally as inconsistent as things come. Not to mention that you are losing extremely valuable tools like calculus in the process. There can be no such thing as intuitionist calculus. You can't do topology and you definitely can't do limits within that framework. Finally, intuitionist physics is total garbage. The red ball is either in the box or it is not in the box. You will NEVER find an empirical case for which that statement isn't true. Standard mathematical logic is, at the end of the day, an extrapolation of physical observations. Intuitionist logic is not. It's simply a contrarian fool's mental paradise.

A properly built house requires metal wood connectors and special wall panels with plenty of specialty fasteners that don't pull out.

There is zero corporate interest in things like astronomy, high energy physics, marine biology (or any other biology save very select topics related to medical research) and so on. Our output of research scientists with PhDs would drop to basically zero if we were to remove taxpayer money from the picture. You would not get any physicists, very few chemists, very few biologists and way fewer medical doctors educated. The US would collapse as a modern state within a few generations because there would be a total lack of people with sufficient knowledge about basic technologies like semiconductors and optical devices.

There are good reasons to assume that at the cosmic scale and in the presence of very strong gravity it is neither.

  4982. The range of possible internal states that a quantum computer can represent grows exponentially with the size of the machine, while it only grows in a linear fashion in an analog or digital computer. So in theory a quantum computer can compute much more efficiently with the same amount of matter. My intuition tells me that this is not quite so in practice, but there is still an enormous advantage to be gained. In a classical computer only the properly structured switching elements are computing. In a quantum computer basically every atom of even the unstructured parts of the machine can be used for the computation. That it still an enormous gain of at least six orders of magnitude, or so, potentially even more.

  4984.  @isntitabeautifulday1648  The problem with science journalism is that it has to reduce ever more complex research to articles that suit people with every shorter attention spans. That's just no a winnable game. As much as it pains me to say this, but society always was and, as long as there will be ordinary humans around, always will be split in two: those few in the know and then everybody else. It would be nice if journalism could bridge the divide even for politically important information, but even that is not happening. The majority of people want journalists to repeat their own opinions. They don't want to be told that their own imagination about the world is completely wrong. Can the average person stay informed about the world? Yes, it's easier then ever. Does the average person want to be informed? No. I am afraid not. One can lead horses to the water, as they say, but one can't make them drink.

  4985. von Neumann was one of the best mathematicians who ever lived, but he could not understand the meaning of quantum mechanics at all.

  4986.  @ValidatingUsername  We have known how quantum mechanics works since 1927. We know how to derive it from first principles, too. All you need is Kolmogorov's axioms and a trivial application of Pythagoras. A congenial mathematician like von Neumann should have seen that in his sleep. And yet he didn't. ;-)
    1
  4987.  @ValidatingUsername  They all thought that quanta are classical objects. That's not the case. Quanta are physical property exchanges. The second problem is that quantum mechanics follows from relativity and for the first 30 years it was treated entirely from the Galilean point of view. Feynman diagrams are still not properly understood by most people. They are a very nice theoretical tool but lead to an awfully flawed intuition in which space is filled to the brim with virtual particles. It's the other way around. Space is completely empty. It is completely empty at all times. That's what relativity tells us.
    1
  4988.  @ValidatingUsername  Never. 99 of 100 physicists do, in my opinion, not understand what quantum mechanics is about. They don't have to. QM is a theory that is very suitable to a "shut up and calculate" approach. Even of you have wildly wrong ideas about what you are dealing with the math returns the correct answer. You can try it for yourself. Ask any physicist (other than me) how and more importantly why quantum mechanics can be derived algebraically from Kolmogorov. They won't be able to tell you. Most of them will probably think that you are trolling them. You will most certainly not make friends. ;-)

  4990. This is experimentally testable. The "outside of the universe" is right here. Your inside is connected to that outside. That also means that energy, momentum, angular momentum and charge has to bleed from the universe to that outside. We could detect these local violations, if they existed. So far none have been seen, so if your "outside of the universe" exists, then it's below the detection limit of our most sensitive experiments, right now.
    1
  4991.  @ellennoone8313  No, there does not have to be an outside. You just have to learn a bit more math than you are comfortable with. A simple example of a geometric figure that does not have an outside is a circle. A circle has an embedding in a flat, two dimensional space. That, however, is a different concept than "outside". The outside of a circle would be two points at its ends. Can you find them? Me neither. ;-)
    1
  4992.  @ellennoone8313  Yes, that is a higher dimensional flat embedding. The dimensionality of an embedding depends on the properties of the manifold. For a flat Minkowski spacetime the minimal number of embedding dimensions is six, if I remember correctly and for a general metric it's ten. Sounds familiar? The ten dimensions show up in string theory over and over, again. People have done experiments to see if energy, momentum and angular momentum are bleeding into such embedding dimensions. So far that search is negative and that's the end of your story at this point, unless you want to start a religion to get a tax break from the US government, that is. ;-) At energies above 1TeV it's another story, but for that you will have to give us a few hundred billion dollars to construct a larger accelerator, at the very least, and even then chances of finding higher embedding dimensions are slim to none at this point.
    1
  4993.  @ellennoone8313  Yes, A sphere in a flat space is called an embedding. Look, just because you don't even know the terms doesn't do anything to nature or to the fact that any and all of this has been considered numerous times by physicists and that much of it has been experimentally tested, already. We are way ahead of you, you just never read the books and papers. ;-)

  4997.  @ZigSputnik  A trivial problem of QFT is that all of its predictions are asymptotic, interaction-free plane waves at infinity, i.e. elements of the free theory. If we turn interaction on, then scattering happens everywhere, i.e. there are no free states, at all. Over an infinite distance the universe is always completely opaque. You can't solve that with some high energy cutoff scale because it doesn't happen at high energy. It happens at all energies and at all scales.

  5029. Quantum mechanics doesn't consider time as absolute. Most people are simply not trained in relativistic quantum field theory and they only know the non-relativistic toy model. Things that are "hard" to understand in that toy model (like entanglement and locality) become trivial once you start reasoning about them in a relativistic framework. That's not a physics problem. It's a poor physics education problem. You don't need quantum mechanics to tell you what "measurement" means. Classical thermodynamics does that, already. That lack of understanding is also an indication of very poor physics education.
    1
  5030.  @navpreetsinghnoorie1942  There is no measurement problem in quantum mechanics. Every day physicists at CERN and other places are making trillions of single quantum measurements. Not once does nature present a problem to them. There is a lot of poor understanding about what measurement means around, though. A measurement is simply an irreversible energy transfer. It is that in both classical mechanics and in quantum theory. In classical mechanics we simply don't care because there is plenty of energy to be measured, so we aren't disrupting the system that we are making that measurement on. In quantum mechanics however the energy that we are measuring (the quantum) is the entire energy of the system. After the measurement that energy is gone and the system has been completely destroyed. That's the actual physics of measurement in quantum theory. In 1931 or so a guy named von Neumann wrote a book about the mathematics of quantum theory. In that book "measurement" becomes redefined as a histogram of such single quantum measurements on an infinite ensemble of identical copies of the actual physical quantum system. And with that the mathematician von Neumann confused half a dozen generations of theorists about the meaning of "measurement". Some of these theorists are so confused that they keep going around claiming that there has to be a problem. There isn't. They simply didn't dare to look at what an actual physical measurement is and the math they keep staring at won't tell them if they don't open a paper written before von Neumann's book. If you dare to look at Heisenberg's matrix mechanics papers, however, it should become very obvious what the connection between actual physics and von Neumann's math is. I will let you do that on your own time. Good luck! :-)

  5034. One can make one. Imagine a bomb with a battery. When it's on, the battery operates an electromagnetic lever that exposes the photosensor to the outside world. Without battery the photosensor retracts into the bomb. Now... is that how one would build a bomb? No, of course not. It's just another layer of Rube-Goldberg thinking that the authors of this experiment had to build in to get to something that they considered an "interesting" result. There is, of course, nothing interesting about it. The bomb is a completely classical detector. It has no quantum state itself, so whatever quantum system we build around it, it's not going to change how it works. At most we are ever going to measure the behavior of the quantum system (in this case the mirrors) themselves.

  5035. Wave functions are descriptions of unmeasured ensembles. This has nothing to do with epistemology. We know with equal certainty that the outcome of a single dice roll is a number between and one six and that, on average, all numbers come out equally often when we roll fair dice. Both are knowledge, they are just no the same knowledge. The quantum mechanical wave function is simply the knowledge we have about expectation values.

  5036.  @davidrobinson7684  Schroedinger's cat was simply an expression of Schroedinger's personal confusion about quantum mechanics. He can't teach you anything about the subject because he didn't understand it himself. That was almost 90 years ago, by the way. It's about as relevant as geology without plate tectonics would be today. If you want to understand quantum mechanics, then you have to read Heisenberg (matrix mechanics), Mott (Mott problem), Dirac and Feynman (relativistic theory) and work your way towards a modern understanding of relativistic field theory.

  5054. Yes, in China it did, but not because of inflation. The GDP per capita in China has risen tenfold over twenty years. That's good for the country, but it means that China is no longer competitive in many low cost goods. Other countries are now cheaper. Germany doesn't make those goods to begin with and therefor doesn't have that problem.

  5060. Nope. First of all, interference is a linear effect, which literally means that there are no interactions, whatsoever. One part of the wave passes through another without either of them being changed in the slightest. Curiously, humans are having a great deal of intellectual trouble with the absence of interaction. One can see the same problem in relativity, where it is the absence of a global coordinate system that causes all kinds of interesting (and counter-intuitive) effects.

No, not yet. You still have many years of crappy work ahead of you before that becomes an issue. What may start eating into your income within a decade or so might be new construction techniques that use prefab wall elements and 3d printing around pre-assembled service pipes. The US is conservative when it comes to the adoption of new construction techniques, though, so we may be seeing stick frame construction techniques being the dominant approach for a long time to come. Asia and Europe might be switching over faster.

We teach this correctly in high school when we explain the photoelectric effect, but if you go to university you are being told in your first quantum theory class that it's all about "particles". That, unfortunately, is not correct. The particle language is a historical artifact that originated in the 1920s at the beginning of quantum mechanics when people were still confused and it has been retained by textbook authors through the years. Most physicists simply adopt this language without thinking much about its implications. For most applications within physics the difference doesn't matter, but if you are really trying to understand what quantum mechanics is and what it actually does, then the difference between a small object and a small amount of energy is absolutely crucial.

  5121. It's a double whammy. China has generated a very large pool of four year degree holders, which are a mismatch to the still active parts of the labor market. At the same time the population is aging out, so the older adults who had an active working life while the salaries were still rising exponentially are now retiring. They have taken the cream off China's spectacular economic rise and are now leaving the young people with inflated prices and no income opportunities. The government policies of cracking down on innovative companies do not help. One can't run a country the size of China with the industries of yesteryear.

  5123.  @michaelkaliski7651  No, optical photons do not, but photons at high energies do. That's because the electromagnetic field has coupling terms to all other charged quantum fields (like electrons, muons, quarks etc.). The perturbation theoretical model of a photon-photon process requires a virtual pair of one of those other fields in the intermediate state. That's math, of course. In reality the physical vacuum is "non-linear". It's just not directly non-linear but it has a large number of constituents that couple in a bi-linear fashion. The bi-linearity leads to an EFFECTIVE or EMERGENT non-linearity. Yes, nature is complicated. If it weren't, then we would not be here. There would, at most, be a free photon gas. How boring.

  5173.  @Treblaine  That's basically every old building in Germany. I have been in some from as late as the 1970s that had mold smell all year long. Until such a building has been renovated and retrofitted these problems won't go away with any amount of ventilation. It has nothing to do with heat pumps. It's just poor construction during the (middle) ages (and beyond). Superinsulation is, of course, a bad idea. It is mostly being pushed by people who are trying to sell superinsulation. It's also completely unnecessary. One can build very nice homes with very low heating bills with very conventional building techniques and even retrofitting is usually not a big deal.
    1
  5174.  @Treblaine Design by bureaucracy tends to go overboard with regulations. R-20 in all building is better than R-120 in a few buildings. That we don't have enough energy is simply not true. We are merely using it poorly. Our ancestors were living and freezing in unheated buildings. Those overcoats that you see on old paintings... those were not just for fashion. People needed them because the average indoors temperature in winter was maybe 5 degrees C. If you had 10 degrees C in your bedroom or above, then you were either lucky rich or you were sleeping next to the cow and the horse. Lung disease was common, with or without coal, coal just caused a different form of it than sleeping in the cold. Like you said, Germany is a really bad example for everything. They are doing everything in absolutes. "Wollt Ihr den totalen Krieg?" is the standard setting of the German soul. All or nothing, with little room for compromise. I wouldn't take that seriously. As long as people and countries are continuing to transition to renewable energy at this pace we will be all A-OK - in terms of energy consumption. The climate is probably a lost cause at this point. We can't CO2-save ourselves out of Noah's real flood, manmade version. We may be able to use some serious geo-engineering. Elon Musk now has a rocket that can take a lot of foil into orbit... and he will be able to launch it a hundred times a day. That will do it. The astronomers will, of course, get very spotty vision, but that's OK. Elon Musk's rocket can also launch all of their space observatories. ;-)

  5191.  @honaleri  Dude, I don't care about your emotional problems with authority. I told you the correct solution to your question: In physics a measurement is an irreversible energy transfer. It has to be an irreversible process because we demand it to leave a lasting record. It has to be a finite transfer of energy because of thermal noise due to the third law of thermodynamics. If we want the measurement to be reliable it has to be above the noise floor. :-) Yes, it is that easy. That you don't know something this trivial about physics completely disqualifies you in this field. That is all there is to it. :-)

  5192.  @honaleri  Sorry to inform you, but your entire first post was nonsense. I know where you got it from. It's called the "Heisenberg microscope" and it's Heisenberg's equivalent of Schroedinger's cat. If you read Heisenberg's original publications then you will see that the young Heisenberg had an incredible intuition for the ontological questions. Initially he got things right but then he aged and he developed a "philosophy of physics" and that's when he got it all wrong. His later writings are total garbage. The simple fact is that particles don't exist. Quantum mechanics is not about objects. It's about energy, momentum, angular momentum and charge exchange between system. If you know that and you also know that individual quantum detections are statistically independent, then you can derive all of quantum mechanics from Kolmogorov's axioms in a few pages of high school level algebra. There is absolutely no need for guesswork here. The founders had to guess a lot of things, but today we know how to derive all of this systematically. We do not teach this properly, though. Not even at the university level. If you want to get a really good understanding, then you will have to dig through the primary literature yourself. It's all there in the physics library. Peace!

  5220. It isn't a probability density function. That's one of the few glaring mistakes that many standard QM textbooks are sharing. To get a probability out of the wave function we have to sandwich a projection operator inbetween the wave function and its complex conjugate that describes the spectrum of the measurement system (that formula is called the Born rule). If we work in a position representation AND we are measuring position with arbitrary resolution (which no actual physical system can do), then that projection operator happens to be a unity operator. It's a mathematical corner case of the calculus that gives us different quantum mechanical measurements that is being frequently misinterpreted as a property of the wave function. The SE uses a unitary operator to describe the dynamic, so the total integral over the wave function stays the same. That, however, is NOT about the probability of finding the system in some state of space. It's about the total number of individual copies in the quantum mechanical ensemble staying unchanged. We start with an infinite number of systems and we end up with the exact same number of systems.

The result is the same: the world has enough money to do business. Do you know what causes economic crises? When there is not enough money going around. That is catastrophic because then people can't pay their bills and then the folks who don't get paid can't pay theirs, either and so on and within a few months the entire world economy freezes. And then a few years later you have war. ;-)

  5237.  @chaosopher23  OK. Now you are making sense. Honestly, travel is overrated. Flying is great the first and second and third time, then the novelty of being locked into an aluminum tube with hundreds of others wears off quickly. And, no, hyperloop does not scale to cross-continental distances, planes are better at those. It could go up and down the East and West Coast in the US and connect places in large states like Texas and California and that's that. I doubt there is enough demand for most of that, though. Where it could shine might be cross-metro traffic. A typical rapid transit system is limited to an average speed of roughly 20-30 miles per hour. That's not fast enough for many large metro areas. Suburbs are now 50-60 miles outside of the city centers. This requires 200mph transportation systems to be comfortably reachable.
    1
  5238.  @chaosopher23  There are more problems than just acceleration. Frequent stops slow trains to a crawl. Single rail lines make it next to impossible to run a fast train with less frequent stops in parallel with slow ones that stop everywhere. You are correct that frequency is also a problem, so are connections. I had a commute where the bus would leave empty just as the train would roll into the station. Then fifteen people would be waiting at the bus stop for half an hour.
    1
  5239.  @chaosopher23  Yes, we can, depending on the area. In places that had train lines built before we built houses like Europe and Japan that's fine. In places like China where they can tear down whatever they want at any time, it's fine. In most of the rest of the world... not so easy. I am not betting on rail as the solution to these intermediate distance problems in the US. Faster cars are much more likely to solve the problem. We have the highways, we just have to double the speed limit (Germany has seen those kinds of driving conditions on the Autobahn for many decades). What we lack are highway on- and off-ramps. I think that's really where tunneling will come in handy. We can double or triple the transportation capacity of old highways by building short tunneled ramps and we can tunnel underneath residential areas without triggering any NIMBY.

  5240.  @chaosopher23  I think Boston's big dig showed that it can be done, if at high cost. Roads are, whether we like it or not, the only solution to the last mile problem. We aren't going to build a monorail to every neighborhood. Having said this, the US has unique transportation problems. What does not work here works just fine in many European and Asian cities.

In an ideal case inheritance allows trivial code reuse and avoids a runtime penalty of one case statement per method. That's a few tens of ns on a modern machine. In return for that your entire team may have to refactor constantly whenever you find that you need to change the dependencies of a single method. Yeah! You are such a smart guy. Not. :-)

    1
  5249. I don't know why your reply doesn't show, but I agree. It's a times scale separation problem. For low frequencies the shorted transmission line acts like an inductance. For short timescales it acts like a capacitor formed by a tiny stretch of it. Between those two extremes we have to analyze it as a transmission line. And technically it's also an antenna, so a small part of the energy will be radiated to free space. That alone makes it impossible to analyze this system with any kind of closed form formula. We can only assume reasonable approximations of its behavior for certain time and frequency ranges. It's one of those problems that are easily misrepresented by the way they are being asked. There are no easy answers here. One has to go through Maxwell's equations in one form or another.

  5251. Because it is also isolated and therefor the trigger system is also not in a classical state from the viewpoint of an external observer. The "solution" to this was known long before Schroedinger. It's called the "Poincare recurrence theorem". It basically says that an isolated system has a finite phase space and within that phase space the system takes on all possible states if we are willing to wait long enough. This means that no matter how unlikely the initial state was, eventually, after a very, very, very long time the system will return to its initial state. The so called "Poincare recurrence time scale" is insanely long, though. Much, much longer than the lifetime of the universe. And the quantum mechanical recurrence time scale is much longer than that, still. But since Schroedinger didn't perform a time scale separation in his example his argument that we don't know if the cat lives or dies is valid. Eventually the cat will live, again (for a very short amount of time). This doesn't contradict the reality that a cat in a closed box is always dead (because it runs out of oxygen). Reality is simply the short term solution and Schroedinger's choice of superposition is the long term solution. One can calculate this explicitly for an atomic system with an initial state <excited atom| vacuum ground state| that decays into a new state <atom in ground state| single photon in vacuum|. In a completely isolated (mirrored) box the photon emitted by the atom will, eventually, be reabsorbed by the atom and it will get back to its initial excited state again. That is the real solution to Schroedinger's cat. It's trivial and says absolutely nothing about quantum mechanics.

  5261. It wasn't supposed to. It was meant to invalidate the Copenhagen interpretation by giving a nonsensical counterexample. What it actually does is to give us a flawed analysis, i.e. it is at most a paradox, which is a teaching tool to demonstrate how not to think about something. Since it never comes with a resolution it doesn't do that, either.

  5262. The equations are not the same. To get from Newtonian gravity to Einstein you have to have good tests for the strong equivalence principle. In Newton's theory m is both an inertial mass and a gravitational charge. Newton's weak equivalence principle limits of how much these masses could differ was around one part in 1000 and that was only possible on dense materials because they didn't have good vacuum technology, yet. Today we have experiments that have tested this weak equivalence principle to one part in 10^15. We still lack observations that extend this to e.g. black holes and it's not clear that it holds for low density (e.g. galaxies or the entire universe), either. If the equivalence principle breaks down for very dense objects or for objects with very low density, then we need a very different theory of gravity that is neither Newtonian or GR.

  5269. Why is having old people around problematic? Old people have a finite shelf life. It expires rather quickly once they reach approx. eighty years of age. The longer we keep people healthy, the less care they need at the end. Much of that care can be automated these days and the remainder will give jobs to many young people. Because, see, having a lot of young people around is very, very problematic. Why, do you think, were they fighting so many wars in the past? Because they had plenty of young men who didn't have a job. These young men weren't the first born sons, so they couldn't inherit the farm. Their older brothers couldn't keep them around because there wasn't enough food and they were aggressive because they had no future and couldn't marry, either. Becoming a soldier was one way out of that hopeless existence. You got paid and you either died quickly or you rose up the ranks and then you could actually make a life for yourself by serving a nobleman. Today we don't even have that mechanism. Look at China's population dynamics. Enormous youth unemployment and hopelessness among young males who, again, can't afford to get married. And this in a country that is aging rapidly! What, do you think, is the future going to look like in Africa where that problem is ten times as pronounced? Grim. So, yeah. Lot of old people and few young are better, not worse.

  5277. C and C++ are not "error prone". They simply let you do more than Rust does. Technically there are no such things as "programming errors". There is only a disconnect between the programmer's mental model of what the code does and the actual reality of what the code does. All of my buffers are allocated statically, they are powers of two sized and I generally use a binary mask for the index. That's 100% buffer overflow safe. Rust can't do any better than that, either for scenarios which do not require dynamic memory allocation. At most it can make dynamic memory allocation more convenient than my programming model would. I use finite state machines for parsing of datagrams and they always include conditions that lead to one or several "invalid" states. Rust can't do any better than that, either, because it does not have a mathematical prover that can prove that your datagrams are safe. You have to make sure of that. Using these techniques I have programs out in industrial applications that have 100% uptime and zero known bugs. If that is what you need, then you just have to use your tools in ways that make sure that that is what you get. Relying on a language to do the thinking for you is a guaranteed recipe for failure.

It doesn't matter how you do these measurements. They always result in random looking sequences. The only thing entanglement does is to give us a non-trivial correlation between these sequences... but to find that correlation both have to be compared with each other, which can't be done any faster than with ordinary speed of light communication.

  5297.  @cetus4449  Sharp sticks in the ground or even just randomly dug holes will do that just fine because the animal doesn't have to die. A serious injury to its legs will make the horse useless. This idea that they sent in the cavalry against foot soldiers behind barricades right away is probably completely wrong. Cavalry was extremely expensive. It's much cheaper to let foot soldiers slug it out, first, get the enemy to abandon fortified positions and then finish the running soldiers in disarray off with a cavalry attack. A man on a horse is much, much more efficient as an executioner than as an actual fighter.

  5298.  @cetus4449  Riding a horse attack against a machine gun or even against people with muzzle loaders is, at most, insanity, it's not a good use of a horse or the man on it, so I don't take the use of horses in gunpowder and explosives dominated wars seriously. From what I heard the initial use of horses was as the internal combustion engine of the war chariots. They are basically the armored troop carriers/tanks of their time. A driver accompanied by an archer and/or a man with a spear/shield/sword. A fast, deadly and partially armored combination with specialized functions that can get around enemy formations quickly and attack from the back and the side while usually staying at a distance. The stability of the platform for the archer (who could carry more arrows in a more convenient location than a rider) and the built in redundancy (multiple men, multiple horses) would have made it even more deadly. It certainly sounds like a better choice of weapon for the fight on even ground than a guy who wobbles around in a (not very good) saddle.

  5299.  @cetus4449  That's just a horse show. Those guys would have been decimated by professional soldiers back then. One should give the Mongolians far more credit than riding and shooting arrows, anyway. They were skilled politicians and had well trained generals who waged war based on carefully gathered information about the enemy. Even so they did not manage to invade parts of Europe that were well defended by fortified castles and that had well organized armies. The Mongol Empire mostly burned itself through vast lands that were poorly equipped to put up resistance against a professionally lead army. After they met men who knew to fight the party was mostly over.

  5306. There is a simple reason why Russia is attacking random civilian targets at this time: they want Ukraine to disperse its air defense systems, which would leave valuable targets more vulnerable. What are the valuable targets? Ukraine has been building up its own defense industry over the last year and a half. They are now producing long range weapons systems and they will soon have missiles that can reach Moscow and beyond. Those facilities need to be protected and they are. Russia is, for good reasons, extremely afraid of the products of these facilities. :-)

  5314. That's the difference between probability theory (it has a linear measure) and quantum mechanics (with a quadratic measure). We aren't looking for objects at all here. Quanta are small amounts of energy. Energy doesn't behave like an object, not even in classical physics.
    1
  5315. ​ @rossholst5315  What are you trying to do? Model a classical system like a falling ball with quantum mechanics? For that you have to solve the SE for that potential, then approximate your object with something like a very narrow Gaussian at some point in the potential and then solve the time evolution for that potential. Can be done, has been done (e.g. for particle in a box systems, linear harmonic oscillators, gravitational potentials, the Kepler problem etc..). The classical dynamics can be recovered to some extent for the case of very large quantum numbers. The wave function of that solution will oscillate extremely rapidly because n is so high and the classical solution is basically the result of averaging around these rapid oscillations. This is not how nature creates reality, though. That happens through continuous weak measurement. The relevant search term is "Mott Problem".
    1
  5316.  @rossholst5315  A simple quantum system doesn't oscillate at all. It exchanges energy irreversibly with its environment. What oscillates is the quantum mechanical ensemble of the system, if we go to high enough excitations, and a large number of coupled quantum systems like a laser. Oscillation is an emergent phenomenon. The mental model that photons are passing the filters is simply wrong. There are no photons in the free field. Photons are the irreversible energy exchanges at source and detector. Copenhagen makes this completely obvious, most people are simply not paying attention to its structure.
    1
  5317.  @rossholst5315  How much energy passes through these filters can be predicted perfectly fine with Maxwell's equations. There is no quantum mechanics here. There are only tons of people who don't understand physics. :-)

  5333. He is not wrong, though. The actual elephant has been in the room since Tesla has begun shipping the Model S in 2012. At that point all arguments in favor of the ICE were over. An intelligent person doesn't argue with reality and they never argue with a superior product in an attractive package. Look, Nokia wasn't bad. Their phones weren't useless pieces of trash. Quite the contrary. Still, their phone market share went from around 50% to a few percent in a matter of six years, or so. Automotive companies have a longer decline time scale because the product is longer lived, but the dynamics are the same. The better is the enemy of the good. Anybody who doesn't get that finds himself locked out of the market sooner or later.

  5344. CS is NOT a team programming class. It teaches you the theory of systems that perform computations rationally. It does not teach you how to build and operate engineering teams. That's a matter for organizational research. Neither is it a good idea to throw students who don't have the maturity, yet, to skeptically analyze their own work into any form of team where they are being subjected to group criticism. You may want to talk to your psychology department about that problem. Lastly, the world looks vastly different at that level depending on whether you are being paid nothing or $50k-250k in annual salary. It's much, much easier to put up with the team programming crap if you are salaried. A student who is getting deeply into debt just for learning the basics doesn't need the stress of a team programming task on top of that. Most probably can't handle it, either.

  5374. Only logarithmically, if I remember the formulas for transmission lines correctly. It's difficult to make transmission lines much over 200Ohm (the impedance of the vacuum is only 377Ohm) and getting below a few ten Ohm leads to very small gaps between linear conductors. If we want much lower impedances (for ground/power plane decoupling on PCBs) then we have to sandwich multiple layers together with thin dielectrics. At multi-GHz frequencies even that fails because the effective "circle of influence" at that frequency is an inch or less. There is an entire class of high speed PCB consultant who does nothing else than to solve this problem for people who don't understand it and who can't make high speed boards.

  5409. Superposition is not an interaction. It's caused by the linearity of the theory. That linearity, OTOH, is due to the fact that the members of the quantum mechanical ensemble are completely independent of each other (and this is BY DEFINITION of the theory!). The reason why the average person thinks that superposition is some magical property is because we are not teaching the solution theory of linear partial differential equations in school properly.
    1
  5410.  @winstongludovatz111  The SE does not describe the evolution of a single system. It describes the evolution of the ensemble, i.e. of the frequentists averages of an infinite number of repetitions of the same experiment. There is no physical connection between individual copies of the experiment, however, some things stay the same between all copies. In case of the Schroedinger equation it's the classical potential that is always the same and that is enough to cause the patterns to emerge IN THE AVERAGE. This is a general property of all linear partial differential equations. It can be found in classical wave equations, in heat equations and inn the SE. If you continue thinking about it, then it will eventually become "intuitively" clearer why this is so.

There simply is no evidence for anything beyond general relativity at this point. Or, if there is, it's at the level of modified Newtonian gravity, but that is even further removed from the level of quantum mechanics than general relativity is.

  5459.  @itseveryday8600  Let me ask you this: if you were the US government and you would be planning a long term upgrade to all of your military space assets, maybe including a complete revamping of your nuclear defense posture, what would you ask a rocket manufacturer to do for you? Might is look like the reusable rapid launch capable Falcon 9/Falcon Heavy and Starship architecture? Would you love to have the ability to build ultra cheap, liquid fueled ICBMs on a tiny production line in the middle of nowhere from fairly conventional materials (like rolled steel sheet...) with cheap tooling using mostly stock construction equipment? Would you like an ultra high performance rocket engine that costs a quarter of a million dollars a piece to make and of which thousands can be manufactured in a year, if funding becomes available? Would you like the ability to put ten thousand satellites into orbit in less than a decade (each carrying a small re-entry payload...)? So, then, do you get the feeling that SpaceX may not be "just" an effort to get Elon Musk to die on Mars... just not on impact? Can you further imagine that this "humanitarian effort to make mankind multiplanetary" might put the fear of total Armageddon into the hearts and minds of Russian, Chinese and North Korean military planners? :-) And, no, I am not a conspiracy theorist, but I think I can still tell dual-use when I see dual-use.

  5460. I don't know what books you are reading, but in actual quantum mechanics textbooks quantum mechanics is fully local but there are non-separable states. The locality is needed to satisfy special relativity and the non-separability is caused by special relativity in return. Anybody who tells you differently is simply lying to you.

  5468. It wasn't made by a good physicist. The idea came from one of Wheeler's students. Hugh Everett III proved in the second sentence of his thesis that hid didn't understand quantum mechanics. That's most likely because his advisor Wheeler and some of the professors who taught him didn't understand it, either. He was simply repeating nonsensical language that was around at the time and that is still in use today. People think in language and whenever we chose the wrong language we tend to drift into nonsense. That is all that happened here.

Imagine having two dice. One only has sides with even numbers. The other one has sides with odd numbers only. Separate them randomly and send them far apart just like the envelopes. Did either of the two dice have a definitive face value during shipping? No. Will there be a correlation between outcomes once both receivers start throwing them? Yes, because we can still tell that the other person received the even numbered one if we throw ours just once and get an odd number as outcome.

  5498. The nucleus is not in superposition, either. What is in superposition is the wave function that describes the average behavior of an infinite number of copies of the experiment. This is perfectly analogous to the case of classical probabilities. Dice that are still rolling are not in a superposition of the numbers 1 to 6. They are simply in no state that one could describe with 1 to 6 at all (because they have a second set of properties that are not static: momentum and angular momentum). Where quantum mechanics differs from dice is the "readout" mechanics. Dice have one standard readout: it's the friction of the table that brings them to a halt. The equivalent of "friction" in quantum mechanics is the energy transfer to a measurement system, which depends in the internal details of the measurement system. That's the reason why not all measurements are equal and not all of them are interchangeable.
    1
  5499. Classical physics is not time reversible. Proof? A global lubricant market with an annual revenue of over $100 billion. Only the most trivial examples of classical systems are time reversible, but one can also give absolutely trivial examples of dynamically irreversible classical systems. A ball rolling down a hill (inclined plane), for instance. Almost all n-body systems in Newtonian gravity are irreversible. In practice this is actually important because it predicts the instability of planetary systems, globular clusters, galaxies etc..

    1
  5503.  @namehidden8854  The point is that there is no "godlike perspective". Not in science, not in mathematics, not in computer science. That's just some bullshit that they believed in religiously in the 18th and 19th centuries (much less so later, though, the writing was kind of on the wall by the 1880s, I believe). The simple fact is that Newton already noticed that he couldn't solve the three-body problem. We still can't solve it. Nobody ever will. It actually turns out that one can only solve roughly one dozen classes of (so called integrable) Hamiltonians exactly. Among an infinity of an infinity (we are talking about the cardinality of real valued functions here, not just the cardinality of vector spaces) of cases we can solve a dozen. THAT is the power limit of physics. In mathematics they have Goedel's theorems and in computer science there are the related halt-problem and similar questions about the limits of computation. Science is inherently limited. One has to accept that and play to the best of ones abilities within those limits. People need to stop dragging these bs ideas about unlimited powers and "top-down-views" into the discussion. Those are long failed philosophical concepts, nothing less, nothing more. Reality is much more sobering... and also much more interesting.

  5508. Why? Spinning something without knowing its orientation before the spin creates something with unknown orientation. So your spinning operation went from "unknown" to "unknown", which is no physical change at all. You are basically still believing in the existence of an actual, objective state before the measurement and nature keeps saying "Nope, I don't care. If you don't know, then I don't know.". Some people call that "realism", but in reality it's actually a blindness to the facts.

  5509. Software is generally "licensed". If you were to "sell" software, that would mean you would sell the source code and whatever else is required to produce the final software that is being "licensed" to the user. This is a quirky detail of the law. It also applies to many other things today. Drugs, for instance, are almost always being licensed unless there is a wholesale M&A of the inventor company by a second, usually larger, company. That is not the problem. A license is good enough for most users.

  5523. 1) There is no requirement that a theory has to allow the solution of every problem. See the three body problem in classical mechanics. 2) The quantum-classical boundary has been solved in 1929 by Mott. 3) That's a problem with general relativity. GR is based on the assumption that the equivalence principle is valid. We demonstrate in high school with a fall tube that the equivalence principle is NOT valid in general. It is only valid if all other forces are suppressed. 4) The world is not deterministic. The only people who claimed that it is deterministic lived in the 18th and 19th centuries and they made that claim as an obviously false extrapolation of ONE success of Newtonian mechanics: the solution to the Kepler problem. That brings you back to 5)... even Newton knew, already, that he could not find a deterministic solution to the three body problem. Today we know that such a solution does not exist and why it can't exist.

Absolutely nothing good can come out of such a mindset. We have been here before, by the way, during the Bolshevik Revolution, which destroyed science in Russia for a generation, and the Cultural Revolution, which has set China back by half a century. It still hasn't fully recovered. And that is, ultimately, the actual goal here. To destroy the West for good with a "cultural revolution" that will have similarly devastating effects. Who has an interest in that? The very countries that did it to themselves once, already.

Your argument with light cones is the correct way of looking at it. The two measurements in this system can have spacelike separation, in which case they can't have a causal connection (some observers will see A before B and others will see B before A). That is all there is to it. Relativity rules out any other solution.

  5541. "Dark matter" is the name for the observation that there seems to be more gravitation than is being predicted by Newton for the amount of visible matter. Dark matter fields are a perfectly testable hypothesis to explain the dark matter observation. If we fail to find them in microscopic experiments, then they can be ruled out. That is exactly how science should work. This is much, much harder with modified theories of gravity. There would be no such microscopic tests. We can add as many higher order terms as we like and slap an arbitrary coupling coefficient on every one of those terms and there is no microscopic test to rule them out. I find that much less "scientific".

Trump is right about one thing: Europe has been complacent. That complacency is coming to a screeching halt exactly because the US is not reliable. The Europeans have to correct that and they will. This will give the US the freedom to operate in the Pacific theatre of the 21st century cold war with China.

  5578.  @maxmax9050  What is strange to most people is a false explanation. If you go into the lab and you start doing actual quantum measurements then you will be bored out of your mind because absolutely nothing strange is happening at all. And if you want to summarize quantum mechanics theoretically, that's even easier: "Quantum mechanics is the unitary representation theory of the Poincare group." What's so strange about that, exactly? What is strange is how few people know this and/or why some of them are lying about it on the internet.

  5593. You are free to explain to us how Xi Jinping's policies of perpetuating unnecessary sectors of the economy benefit China in the long term. And while you are at it, please explain how China is going to deal with the 4-2-1-0 family? Is it going to force women to have children they don't want? Will it replace people with robots? What is the game plan for the 21st century? China's leadership is, at the moment, reactive. It is aged out and has only token recipes that are borrowed from the past. Xi playing Mao light is not going to solve the structural issues that every industrialized nation has to face in the 21st century. This is not China's problem. This is a global problem, but installing old man Xi in China to counteract old men Trump and Biden in the US and old man Putin in Russia is a ridiculous strategy in a world that needs Elon Musks by the dozens.

The problem is for those at the bottom. The lack of money causes a lack of economic choices that could lead to the acquisition of wealth. You aren't getting rich by being in survival mode. You are only getting richer by making the right choices... which requires that you have the means to make any effective choices, at all. That is what money allows you to do.

  5618. A single photon makes exactly one dot on the screen. How are you seeing an interference pattern in a single dot? Now, do you mean that you don't understand how the ensemble, i.e. an infinite number of independent repetitions of the experiment makes an interference pattern? Why not? Even the classical electromagnetic field is linear, i.e. it does not interact with itself. So why does it bother you that it does not take any interaction between single photon measurements to create a pattern? The pattern is being created by the strong interaction of the field with the geometry of the slits. That is what modulates the photon distribution.

  5655.  @tejassharma1849  A chess game (including the set of all possible games) is a search problem that can be represented as a tree. The only question you are asking is how to cull the dead branches the most efficiently with the least amount of computation. A good deal of that has already been done by opening libraries and many endgames can probably be searched completely on state of the art hardware. That really just leaves the middlegame unsolved unless you want to introduce new rules... like the requirement that an algorithm should not search more than n-moves ahead or that only m evaluations are allowed in total (and the algorithm can chose how deep/broad it wants to search within that search volume). From a theoretical point of view chess is already a dead game (and probably always was).

  5701. Logic isn't flawed. Logic describes the behavior of classical objects. Quanta are not objects. Quanta are small amounts of energy.

  5707. It is only valid if GR is a correct theory (which it isn't). A better model for a quantum mechanical black hole is more like a two dimensional plane (or torus) that has string hair. Near the surface of the classical singularity plane those hairs would be highly distinguishable, but closer to the event horizon they get dampened. Or maybe one can imagine that most of these hairs never reach the event horizon. One that does can emit a little bit of energy in form of Hawking radiation, probably through tunneling. I might be wrong about that picture. That's just my own homebrew and I am not a theorist, so take with about five metric tons of salt.

  5708. That should have happened seventy years ago. Gaza was a bad idea... especially for the people living there. There is no need to continue bad ideas. Most people from Gaza will find that life is much better elsewhere.

  5726. Interference is a linear phenomenon. It's the absence of interaction, so even "multiple photons" don't interact with each other. The lowest order physical interaction in these systems would cause photons with sum and difference frequencies to appear, i.e. it would change the spectral composition of light. A non-linear field with self-interaction automatically scatters its excitations all over the place, i.e. even a fairly monochromatic source will create higher harmonics and low frequency (near DC) excitations and over a long distance the source will appear washed out as if it had gone trough a fog.

  5727. Probably not at the LHC. There are plans for Higgs factories, but finding a Higgs multiplet is not going to drive the theory. It's already accounted for. What you are asking is basically the same as the question if one can discover nuclear physics by developing more precise analytic methods in organic chemistry. One can not and that's that.

I should respect you for what your Mom did? If that is what you think, then your Mom and Dad did not do a good job raising you, either. Anyway, if this is what you think about reality, then your do-over medal and participation trophy are in the mail. You clearly need and deserve them. ;-) And, no, you didn't make that lovely Spanish fish restaurant, either. That atmosphere is the achievement of the owner and his employees. Neither did you make your phone or the battery or the charge in the battery. You are basically just leeching off other people's work, but you expect me to admire you for that. Dude. Seriously. Just how old are you? ;-) OK, this is getting real fun now. I love talking to immature folks on the internet.

  5777.  @winst0n888  Yeah, kid, I think you need to learn a few things about reality here. Stock markets are privately owned and operated corporations. "public" in this context simply means that the disclosure requirements for the product offerings are significantly different from those of stock offerings that can be sold to large, "professional" investors. :-)

  5778. The mere idea that security exists in this space is a ridiculous misunderstanding of physics. A radio transmitter can always be located simply by the fact that it has to produce an energy flow that is above the noise background of the environment. No matter the protocol, it is always possible to detect the source of the transmission. For a criminal the detection of a police transmitter close to his physical location would usually be enough to seize the criminal activity. It is complete overkill to differentiate between "harmful" and "harmless" police presence for most such activities. That's why the police usually does not care about being listened to.

  5779.  @arctic_haze  The ground state solution of the hydrogen problem does not have a zero in the center. The overlap of the electronic and nuclear wave functions can be easily measured in spin-spin coupling experiments and it leads to effects like electron capture in heavier atoms.

  5780. There was never a good argument for determinism. People didn't believe in determinism until Newton. They may have believed that god, the devil, demons, witches etc.. were throwing wrenches in their daily lives, but they never thought that the outcome of the world was set in stone. That's just not a strategy that one can live by. Then came Newton and he explained Keplerian motion. The philosophers picked that up right away and they said "We can predict ONE example of physical motion perfectly... from which it follows that we can predict ALL physical motion perfectly, from which it follows that we can predict EVERYTHING perfectly, from with it follows that everything is predetermined!". See, this is what binge drinking your own pee does to your brain in the long run. ;-)

  5792. What most religionists mean when they are talking about "atheists" is actually "humanists". They simply don't know the correct terms. Humanists are, indeed, putting humans front and center. We want them to do well and live their lives without fear and pain. We want them to be well fed, clothed, have appropriate housing, education and medical services. We want clean streets and a society that is based on tolerance rather than violence against minorities. Humanism does, indeed, make the world better. It has made the world much better than religion ever has. And THAT is what religious people can't stand. To be proven wrong.
    1
  5793.  @Cowplunk  An atheist is simply a person who doesn't believe the theist bullshit about the tens of thousands of gods. That in itself has no consequences for ones behavior. Being a humanist is what does. Again, I am not responsible for the lack of education of most theists.

    1
  5804.  @passivehouseaustralia4406  Yeah, that sounds good, except that it's total bullshit. That's not how Einstein got to relativity and the modern derivation is about a dozen lines of high school algebra without any need for deep thoughts about light because special relativity has absolutely nothing to do with light. :-)

  5807.  @passivehouseaustralia4406  That all physics is relative was known experimentally at Newton's time (as I said, even Galileo gave you the correct experiments that are equivalent to Einstein's elevator) half a century before Newton, or so. It's really not my problem that you don't know the history of science and that you come to the entirely wrong conclusions about Einstein's work. :-)

  5816.  @tablettablete186  sudo is a naive workaround for the failed "root" concept. The average user should NEVER have to use it. Look, all of this was invented at a time when computer security was not a problem. Today it is. Nobody was doing their bank transactions on a multi-user mainframe in the 1960s and early 1970s. Except for the bank, that is... and they could physically secure their hardware and the only possible "hackers" were their own employees who had hardware access. That made these simple minded concepts somewhat workable. They are not workable today.

  5822. Quantum computing is not profitable, either. None of the quantum computers we have built, so far, are anywhere close to a technologically useful machine. Not that it matters because nobody knows what to do with such a machine to begin with. It simply does not have any conceivable application right now. That's a much bigger problem for the field than the actual construction of such a machine.

  5825. Academia is primarily about teaching. If your problem is that we don't let anybody just teach any nonsense, then you are right. We do not. We have very strict requirements for teaching at this level... which are actually still not strict enough, if you ask me.
    1
  5826.  @georgelionon9050  I don't know what "the science system" is supposed to be. There is academia that teaches and does research. Then there is the national laboratory system for physics that does only research. That's a much easier environment to work in as a scientist. Other countries have equivalents of that. In medicine they have teaching hospitals. Geologists are working for the USGS, which provides a public service relating to health and safety. Oceanographers might be working for NOAA, space scientists are at NASA etc.. Each of these have individual oversight and org charts. They are all, at the end of the day, striving for excellence and have to account to the US taxpayer. If you think that this isn't being taken very seriously, then you must be a Trumper who feeds on fake news.

  5837. Maybe a cursory reading of the old testament would have helped the Palestinians to understand the nature of the Jewish people. They are not eternally nice victims. If they have the means to fight back, they do. And if you think that the Jewish people didn't fight back against the Nazis, then please think again. They fought back on the battlefields of WW II on the side of the allies and they fought back in the laboratories of Los Alamos. I am afraid that you are having a very, very one-sided reading of history. The only thing that saved the Germans from the bombs designed by Jewish physicists was an early end to the war, otherwise they would have hit Berlin and not Hiroshima. It's just a fluke of history that the bombs came six months too late and that Germany was spared.

  5839. Of course. None of this requires any consciousness. You can play the entire game with high energy scattering processes involving tachyons. If you do, then there will be a flood of tachyons coming at you before you even turn on the accelerator. If you just think about building a really high energy accelerator there will be a flood of tachyons coming at you. And boy, if you are thinking about building a really, really high energy accelerator, then the Neanderthals will see a bright light in the sky that will completely wipe out all life on Earth. So don't you dare thinking about accelerators for tachyon research! You don't want to hurt the Neanderthals. ;-)

Unless that irreversible energy flow takes place, that quantum of energy does not even exist.

  5904. Because living in Antarctica (or even Greenland) is a major hassle and logistics problem. The most isolated places that humans have been populating are usually still supplying ample food resources (e.g. from the ocean).

  5907. Let me tell you a story, Dude. My first physics classroom in university had 150 students attending. Some of the first semesters next to me were talking about how to become a professor. I turned around and said this: "Do you see the professor? The guy will have been teaching this class roughly 30 times by the time he retires. Among all these students taking this class ONE will eventually replace him. So that's one in several thousand.". If you elect physics as your major and you can't even do a simple calculation like this in your mind, then you have chosen the wrong major. You would do far better in the liberal arts department. ;-)

    1
  5927. @ The total angular momentum is conserved. This includes the angular momenta of the measurement systems. People who talk about entanglement all day long usually forget that the measurement systems also have to be included. So, no, if you just look at the measured angular momenta (or, better, the spin projections), then it's not even conserved because for two measurement systems that have their projection axes rotated by 90 degrees the correlation between the measured spin projections is zero. However, if you were to measure the total angular momentum of the two measurement systems AFTER the measurements, then you would find the total unchanged, even if the measurement results seem to contradict that.

  5929. Natural immunity totally didn't work for my eight antivaxxer relatives. They got infected for a second time a couple of month's ago. If we take the time since the first infection in mid 2020, then they had, at most, immunity for 18 months, probably less than that. Severity of their symptoms and length of the disease don't seem to have been significantly better, either. In essence... they are suffering for naught and they have been infecting innocent people, too. One of them is a less than one year old baby. What in the world is that good for? Are you trying to kill your own children?

  5946.  @wawawuu1514  The internet is NOT academia. Academia are universities and colleges. Plenty of them allow public visitors to their libraries. At most they ask you to pay an annual user fee on the order of a few ten to a few hundred dollars. Running a library is very expensive and books and journals get damaged by use. Librarians need to pay the rent and so we pay them salaries. Surprise. What these institutions will not ask from you is a per item fee that the publishers are making their money with.
    1
  5947.  @wawawuu1514  Then none of this should a big deal. We are generating scientific knowledge worth tens if not hundreds of billions of dollars a year and we are making it available for non-commercial use for basically for free. If you want a commercial license, then academic institutions will charge you. Depending on what you want to license you may have to pay thousands or even hundreds of millions of dollars for it. This, too, is necessary because the exploitation of inventions is expensive, so if anybody without a commercial license could use it, then corporations would simply not use it... without exclusive licenses one simply can't make a business case for investing the additional product R&D cost.

  5954. The calculation is nonsensical to begin with because protection wanes over time due to decreasing antibody titer and the appearance of new variants. A serious epidemiological model would have to take those factors into account and will easily reproduce the actual annual reappearance of respiratory diseases like the flu and the varieties of the common cold. There simply is no natural immunity against these diseases. Unless we are willing to vaccinate entire populations for multiple years in addition to continued social distancing, this disease will stay with us and there is no guarantee that it will soften its impact on mortality and hospital utilization.

  5962.  @manuell3505  You need 100% uptime, your own quality control (which would include thermal considerations and cycling as well as EMF/EMI), 100% security and 100% supply chain control.

It was always a hobbyist device and as such it works well enough.

  5982.  @kujojotarostandoceanman2641  It has been around for a long time. They used to call it "the Gaia theory". I wasn't much of a fan of it because it sounded like new age nonsense, but if you really think about it, no species can survive without a very large number of other interconnected species. Even the most primitive life relies on a chemical or physical energy source that is provided by abiotic processes (like fusion in the sun) and different chemical sources (and sinks for waste products). So, yeah, life is one of those phenomena for which the usual divide-and-conquer strategy of science only gets us so far. It is a complex emergent phenomenon and we have to learn to analyze its complexities.

  5983. Superposition is the description of what we don't know about a system. In quantum mechanics the "don't know space" can be enormous. In certain cases that can be used to calculate things. Don't let the proofs that quantum algorithms are equivalent to classical algorithms fool you. They only prove that one can always find a quantum algorithm that calculates the same results as a classical algorithm but with uncertainty. It's not a proof that an efficient quantum algorithm exists. My best bet is that there will be a few amazingly efficient quantum algorithms that will give us new insights into the mathematical nature of certain problems (like factoring and prime numbers). In general, however, most problems that only have inefficient classical algorithms will probably turn out to have no more efficient (or far less efficient) quantum algorithms. Just my two cents.

Was Hercules a smart baby, or not? He should have gotten a patent on that one. :-) I didn't draw any conclusion about Jesus other than that it doesn't matter whether he existed or not. It doesn't matter to the atheist because the existence of a human being in antiquity is nothing unusual. The existence of apocalyptic preachers in Judea in the 1st century AD is nothing unusual, either, it seems. That people believe in bullshit is nothing unusual. That people believe in 2000 year old bullshit is nothing unusual as any comparative religion class will teach. You are drawing the entirely wrong conclusions about all of this yourself. None of this requires any belief in anything. This is just the usual human condition.

That's simply not enough to be a good physicist. If you want to see what the top people in the field look like, listen to Witten and Arkani-Hamed. There is an alternative explanation... if she knows what all of this means, then she doesn't mind lying, which is at least a moral flaw.

  6004.  @argynkuketayev4166  Are you saying that the GPS system is useless? It's based on atomic clocks, which require a very intimate knowledge of quantum mechanics. I would argue the opposite. Quantum mechanics is one of the most simple theories in physics and everybody should know at least the basics. Our educators have been agreeing with me on this for about fifty years now, that's why we have been teaching the photoelectric effect in high school for a long time. The problem is that most people don't listen during and don't retain anything of that learning unit. THAT is the problem why nobody understands quantum mechanics. You are correct, of course, that Brian Cox doesn't know enough about it, either, to be able to explain the basics so that anybody can remember.
    1
  6005. ​ @argynkuketayev4166  I agree. YouTube physics is 100% entertainment and almost 0% fact. When it comes to explanations of quantum mechanics almost all of it is nearly completely wrong and not helpful in the least. So why are we trying to teach science to people, anyway? Because having an education elevates man above the beasts of the field. It is meant to remove fear from the hearts and to cause confidence in nature, human society and oneself. Does it work out that way? No, I am afraid it does not. Can I explain quantum mechanics in a few sentences to you? Yes, absolutely. Watch: "A quantum is a small amount of energy. Energy is the ability to carry a piano to the fourth floor of a building. Therefor a quantum is the ability to carry a very small piano to the fourth floor of a very tiny building." That's it. If you can remember that, then you have the basics of quantum mechanics down. The math simply makes this quantitative and in atomic physics we replace "piano" with "quantum state", "building" with "atom" and the fourth floor with an "f-orbital". That's not really that hard, is it? :-)

  6014. A structure has data, a class has data and functions. You can, of course, also stuff a function pointer into a structure, which then becomes more or less equivalent to a class. The important thing for you to keep in mind is that all of this is meta-information. The compiler doesn't give a frell about it. It's all being stripped out on the way to machine code. Structures and classes are organizational tools. They make it easier for you and your fellow programmers to understand how the code is organized, but they don't change how the compiled code behaves (by much, that is, there are differences in heap and stack order of your data that are based on the class hierarchy). The problem with most OOP classes is that they pretend to teach you programming techniques (which they don't), when in reality they are almost solely focused on team organization and software documentation.

The world economy has an annual GDP of almost 100 trillion dollars. And that's only a fraction of the actual real estate and industrial value of the world, which is easily tens of times larger than the GDP. :-)

  6025.  @St37One  Relativity tells us EXACTLY why the universe is not predictable: we have constantly energy flowing in from spacelike separated regions of spacetime. The point in time when we detect this energy (aka "event") is the first (and the last time) this energy can be detected. Nature won't and it can't give us a "heads up" for future events in general. A macroscopic example of this is NASA's "seven minutes of terror" video. During a Mars landing the radio signals from Mars are delayed by something like ten minutes. The actual atmospheric entry sequence, parachute deployment and ignition of landing engines/crane deployment for the lander payload are all over by the time the signal arrives. The ground controllers have no way of influencing these events, but they make a world of a difference to the folks who built the rover: if something goes wrong, they won't have a job for the next five to ten years (well, they have to start over from scratch). If it succeeds, then they will have a toy on Mars to play with. This is an example of non-determinism. The local future does not depend on the local past and present at all. It can not be influenced by any means imaginable and it can't be predicted with any formula from physics. It is like this all over the universe all the time on all temporal and spatial scales. "What happens next" is simply not fully predictable.

  6028.  @akirakosaintjust  That's the thing about reality: it's a very low level thing. If you don't want to mess with it, it will mess with you. I was working on a project once where that cache coherence thing had caused tens of millions in damage and months in delay. A junior programmer had written an "algorithm profiling suite" that performed at least 60 times worse because of his lack of knowledge of cache coherence than the properly optimized code would have. They purchased an entire computing farm because of that guy, which turned out to be way too unwieldy to program. I had pointed out early in the work that his performance estimates were all wrong and in the end it took an "expert" commission to undo the political implications within the project that the rookie's mistakes had caused. That was one my finest "I told you so!" moments. In other words: if you believe that abstraction solves real world problems, then every professional in the world will ask you to hold his beer because he has dozens of stories that proves otherwise. ;-)

  6030. You can generalize that criticism of FP beyond GUI environments: the entire idea that a program is pure (stateless) and immutable is complete bullshit. Not even "Hello World" is that. What you are describing as functional syntax has not much value beyond form. map/filter/reduce are incredibly inefficient algorithmically. I would say that they are basically useless beyond toy problems. Yes, your program might be short... but what good does it do if your CPU is idling 99.8% of the time because of cache misses? ;-)

  6033.  @rhcpmorley  I just gave you the definition of the word "time". "Time is that which the clocks show.". Now you can ask what a clock is and then you get the correct answer about the nature of time. A clock is a local energy reservoir that releases this energy slowly and steadily towards infinity. Time is not about "change". It's about energy flow between any two points in spacetime. More precisely, a time measurement is about establishing the (least impeded) energy flow (causal connection) between such points. It can not flow backwards because there is nothing "lesser" than "least". Easy, isn't it? :-)

  6037. In what function? As a critic of physics DK or as a demonstration of physics DK? He seems to have done a good job about both sides of that problem. His probabilistic interpretations of quantum mechanics are complete bullshit, of course. Probabilistic theories can not be time-reversal invariant and QM is, both in theory and in the closest possible physical form of phase-conjugation experiments. We can show that quantum systems remember their past as long as they are not being subjected to a measurement. The only irreversible aspects of quantum mechanics are preparation and measurement, which means that the only "mysteries" are what preparation and measurement mean. Quantum field theory gives a perfectly natural explanation for both: it's the local interaction of waves coming from and going to infinity. In other words, what gives structure to quantum mechanics is the same thing that causes "time" to exist: the fact that there is way more "out there" than there is "over here". Every physicist who has ever done atomic physics and high energy physics experiments should know this intuitively. There is simply no mystery here, there are only people who don't know enough about physics.

There are secondary phenomena, like "household workers", who are usually young women who are trading their lives for the support of their families. I believe there are approx. 10 million of those in Southeast Asia alone and I have seen the same phenomenon in Mexico. In China one can literally find hordes of uneducated young men and women from villages who are working in the cities as waiters and hotel employees and in factories as line workers. These people are also losing their fertile years to the rut of a capitalist society which thrives on the cheapest labor it can find. In other words, even the money of the rich reduces birth rates among the poor.

  6080.  @willyjacquet4436  I agree with your last part: a lot of refactoring has to be done in OOP to add functionality that wasn't required when the initial architectural decisions were made. So the system may be working, it just doesn't do everything that is required of it for the new version. My point is that if we have to recompile software, then there is always a potential for breaking it. Just because the code is theoretically equivalent doesn't mean that the runtime behaves the same. Bugs that are due to memory layout (like buffer overflows) may show up in one version but not in the other. Memory layout can also introduce hard to track down performance issues because of cache misses: I had to deal with a piece of code in my PhD that ran ten times faster simply by swapping two inner loops... the guy who wrote it was a newbie who knew nothing about cache misses. That isn't even refactoring. That's just code transformations that even modern compilers can do on their own. Refactoring can cause similar issues with cache misses on the program segment. I am not advocating that one can get around architectural changes one way or another, but refactoring is not the cure. It's merely a symptom of the problem and in OOP specifically it seems to be a permanent malaise.

  6113.  @Tomdiana  We aren't limited in materials. Tell me one material that you want to buy that you can't? We are limited on some finished goods right now. Why? Because semiconductors that you don't order don't get made. If they don't get made, then they won't get made for at least half a year. That's simply how long it takes from start to finish to make these things. People didn't order during the pandemic. But now you also can't make twice as many to catch up because production lines are usually utilized to 90% or more and it takes years to build a new production line. This has absolutely nothing to do with monetary policy. We didn't print money to make stuff, anyway. We were printing money so that people who became unemployed could stay in their homes and rental apartments. What would you have done, instead? Let the banks eat it? The landlords who have to pay the banks? Or just evict tens of millions, like we did during the Great Depression? How did that work out? Got some nice photographs by Dorothea Lange out of it, didn't you? Desperate homeless people on the roadside from nowhere to nowhere and in shacks that wouldn't even be used to house chickens today. Oh, yes, and great 1930s pre-code screwball comedies showing actors playing people who were partying while the rest of the country was fighting for survival. Good times! That is what you get from not printing money. It's not rational economic policy. It doesn't work. We tried it. Now, nobody says that printing money is enough. We also have to pry it back from the hands that collect most of it at the end of the day... the 0.01%. That's where higher taxes come in. You giveth and then you taketh away, so you can giveth some more to those who need it.

I am retired and have been frugal all my life. I haven't been living paycheck to paycheck since I had my first student job. I happen to know how to save money. It's not hard. It's also not the economic recipe to success. If you want to spend more money than you have, then you have to improve your income side. That's what counts. How does one do that without having been born rich? By learning. Unless, of course, you are beautiful or very good at sports. Then you can afford to stay stupid. Only then can you afford to stay stupid. So, are you a supermodel or a basketball pro? :-)

  6116.  @Tomdiana  Oh, I am sorry. I didn't know I met a rich guy. Do I need to bow, Sir? ;-) In any case, rich man, only half of all silver production goes into technological applications. The other half is mostly investment and jewelry. Gold is not much different. What's the "green new deal"? Solar panels? That's like 10% of global silver production, less than what's being used in jewelry. Silver production, by the way, is mostly a function of copper (lead etc.) mining. We rarely find high quality silver ores independent of other metals. Hence the production of silver is not actually set by a technology use dominated silver supply-demand equilibrium. Seriously, man, you didn't pay attention in high school when they talked about the mining of metals. :-)

  6120. Shakespeare died in 1616, approx. 15 years before Galileo formulated the relativity principle in one of his books (around 1630), so he just about missed the advent of "modern physics", but he may have been aware of Galileo's discovery of Jupiter's moons (1610). Science journalist Dan Falk has pointed out that his play "Cymbeline" was published only a few months after Galileo's discovery and that it mentions Jupiter and four ghosts dancing in a circle in a dream scene. So, yeah, he may have been inspired by science more than he was by philosophy.

  6122. You aren't missing anything. This is physics bullshit pure. If you think about it rationally then it becomes obvious that each bomb behaves like a classical object: bombs explode whenever they absorb energy (photons are electromagnetic field energy, nothing more, nothing less). No amount of fog and mirrors can convert that classical behavior into quantum mechanics. Moreover, mirrors and beam splitters alone don't make for quantum mechanical experiments (neither do slits). None of these experiments introduces Planck's constant anywhere. It might therefor be zero, it's original value or 137 trillion... the theory wouldn't predict any change in the behavior of the experiment. Why? Because we never leave the realm of classical electromagnetism except at the detector... and those basically just detect quanta with a frequency that is proportional to the classical intensity of the light. Whenever somebody tells you that "there is exactly one photon in the apparatus", that's metaphysical bullshit. It's an untestable assumption. A photon is an irreversible energy transfer. There are no photons without that irreversible event, at all. How much energy was in total in the apparatus can not be known without actually measuring it. All that can be known is how much energy was taken out of the field.

  6125.  @blahdiblah2169  It was never "shut up and calculate". For me it was always "I don't understand QM101 at all, so let's go to the library and see if we can't find something that makes sense". It took me several weeks of more or less random digging in old journals and textbooks, but then I found Feynman's 1948 paper on the path integral formulation of the Schroedinger equation and then the lights went on. From there I began dabbling in quantum field theory and it took me years (I suck at theory) to understand why the QFT guys don't give a frell about measurement operators. And then I did a PhD in experimental high energy physics and there you notice very quickly that what your detectors are measuring are always energy and momentum. You aren't measuring some random linear operator over a general Hilbert space. It's not math but the most concrete physics in the world. It's the relativistic miniature version of collisions between massive objects that you have seen in high school physics, except that there are no massive objects, but the formulas for kinetic energy and momentum exchanges are still valid. And then I read some more about it and I found Mott's paper from 1929 that explains why plane waves with high momenta automatically form particle tracks in detectors and another set of lights went on. And at that point you can completely abandon the QM 101 nonsense about particles. There are no particles. There are only quanta and quanta are energy and momentum and angular momentum exchanges between fields. And once you know all of that, then you can go back and re-read the old papers of Heisenberg and others from the 1920s and you will find that you were never asked to shut up and calculate. It's all in those old papers, already. The entire physics intuition that you needed to make it successfully in QM101 was already there. What had simply happened in my case is that the guy who read QM101 to us (literally... he didn't give a frell) was not a high energy physicist, he didn't care about foundations of quantum mechanics, he had never built a relativistic detector, he had never read a thing about path integrals, he had never read Heisenberg's papers, either. He knew the formalism from abstract modern textbooks that didn't mention any of that and that was enough for him to do his job in solid state physics. He was the last guy on Earth who should have been teaching QM 101. That is not a problem with quantum mechanics. That is a problem with how we teach quantum mechanics to undergrads. And that, my friends, is exactly the state of quantum mechanics "teaching" on the internet. You are getting a completely mutilated version of a non-relativistic approximation of quantum field theory (which is the only real physical theory that is self consistent) presented by people who don't know that what they are showing you is not the real deal. They simply don't know what they don't know. That is physics DK. And now you have to decide if you want to download Mott's 1929 paper and Heisenberg's 1927 papers (or thereabouts) and read a good textbook or two on QFT and go through Feynman's derivation of the path integral for the Schroedinger equation (one of the most beautiful theory papers in all of physics IMHO) or if you want to pretend that you know it all when you don't know anything, whatsoever. Take care.

  6206.  @carparkmartian2193  What contradiction would that be? A lot of what Penrose pushes is total nonsense. The phrase "wave function collapse", for instance, doesn't even appear in well written quantum mechanics textbooks like Sakurai. It has no scientific meaning and you won't find a scientific definition for it anywhere. The wave function isn't "made" of anything. It's a purely abstract mathematical idea by man. It's a concept that only applies to well defined quantum mechanical ensembles. A black hole is not one of those, either, so anything Penrose and some other relativists are telling you about the interplay of quantum mechanics and strong gravity is total nonsense. At most you are telling me here that you don't know what quantum mechanics is and how it works. :-)
    1
  6207.  @carparkmartian2193  von Neumann explains EXACTLY what happens during a quantum measurement. You clearly didn't read the chapter you are referencing. It is NOT collapse of the wave function but irreversible energy transfer. He even says where the energy goes, eventually: it gets radiated away by the measurement system as heat. That's the one and only correct explanation. Dirac made it clear that he understood that quanta are amounts of energy. The measurement process is therefor an energy transfer process. Dirac's work culminated in quantum field theory in which there is not even a measurement process. We are simply looking at scattering of plane waves from infinity to infinity. Griffith's tells you in his foreword that he doesn't understand quantum mechanics and that he only cares about the "shut up and calculate" aspects and then he proceeds in his entire textbook to prove that he indeed does not understand quantum mechanics. It's one of the worst books in the market. It's telling that you didn't give me a meaningful definition, either. You didn't find one, did you? :-) The measurement postulate is NOT a description of collapse. It's a recipe for strong measurement which tells you exactly what is going on in quantum mechanics: it's an irreversible energy transfer between two systems: quanta of energy get transferred from the quantum system to the measurement system. Nothing happens to the original wave function after that. It simply seizes to be a meaningful description of the original quantum mechanical ensemble because the coupling between the two (ensembles of) systems has changed the experiment.
    1
  6208.  @carparkmartian2193  What individual authors think is irrelevant. This is not a he-said-she-said. This is hard science. What happens is easily traceable in the laboratory. In every quantum measurement a quantum of energy flows from one system to another (or to infinity). That's it. No mysteries here whatsoever and this is exactly what the math describes. There are no inconsistencies here, either. Or, if they are, then they are in your head. That's for the psychology department to figure out, it's not a job for the physics department. Energy doesn't reside in "a quantum state". Energy is a property of systems. We teach this in high school, few students are paying attention. At this point I am beginning to doubt that you ever took your high school physics lessons seriously. I don't know what you mean by information, either. There is no such thing in physics. Physics only cares about energy, momentum, angular momentum and charges. Why these quantities and nothing else? Because there are the only locally conserved system quantities. Emmy Noether wants you to hold here beer, right now. People who are talking about information in a physics context simply don't understand physics. We are therefor at the point where I can safely say that you are clueless. ;-)

For one thing they can reduce your call tree from a jumbled mess to a small number of extremely well defined state machines. If you have anything to do with architecture, then you should learn that state machines are inherently safe and provable, while random function calls are the exact opposite.

  6216. Most of the worked out models are either 1d or 2d. The problem is that dimensionality changes the coupling enormously and therefor 1d and 2d models have vastly different properties than 3 dimensional ones. We have experimental systems in 1d and 2d and they do behave as expected. We simply can't do the math beyond that. The person who can will win both a Fields medal and a physics Nobel.

  6217.  @prasannabhat8631  It's not a matter of geometry in this case. It's a matter of how strongly different parts of a system couple to each other as a function of distance. For 1d systems the coupling is independent of distance. For 2d systems it goes down with 1/r, for 3d systems it's 1/r^2 etc.. It's the change from 1/r to 1/r^2 that makes it very hard to make theoretical predictions. It's a hard math problem. We simply can't solve the equations. Not even numerically.

The hardest step may have been from single to multicellular life, after that evolution was extremely rapid. Brains took a while but the development of human intelligence happened in the blink of an evolutionary eye. The transition to artificial life and intelligence which is happening now will take less than a century.

  6245. Not only is it hard to follow, it's also irrelevant to physics. There are no probabilities in physics. In physics we only have outcome frequencies. It is very important to understand that these outcomes are NOT random. We simply can't reconstruct a "classical" causality chain for them, but every outcome "here" is still completely correlated with some other outcomes "over there". That is inevitable because of conservation laws.

Physics is not very enjoyable when you get torn apart by tidal forces seconds after you shout "Eureka! I was right!".

  6287.  @clay-tw5gc  From a physicist's perspective it is. The remainder is basically electrical engineering. Accelerators differ very little from other electrical power facilities. The core elements are similar to what's in your microwave, just far more powerful, and then there are lots and lots of high voltage power supplies. None of that is rocket science. The physics is really just energy input and empty space. You would be surprised how few people are employed worldwide to develop these technologies. It's a handful here and there at high energy physics facilities around the world. That's all it takes. ;-)
    1
  6288.  @clay-tw5gc  There are no particles. There are only quanta of energy. We have been teaching this in high school for over 40 years now. All the properties of these energy exchanges are inherent in the Poincare group, which is the symmetry of empty space. Some of this was already known like 90 years ago, with the entire picture emerging about 60 years ago. You are asking questions of the deep past, scientifically speaking. ;-)
    1
  6289.  @clay-tw5gc  The only "thing" that "exists" at "the extremely small level" is a three dimensional metric manifold with a locally additive property called "energy". Everything else follows from that. There are two remaining problems that need to be solved here: 1) What causes this metric structure (the three effective dimensions are kind of a given because in all other dimensions this construction leads to inconsistencies or nothing) and 2) What selects the low energy world that we are seeing from the infinity of possible high energy solutions to Poincare symmetry? These two questions are equally open in all versions of theory that we know about, right now, even if we look at "not even wrongs" like string theory. Question 2) might be a little easier to attack than question 1).
    1
  6290.  @clay-tw5gc  Energy is energy. It's not localized. Never was, never will be. It's the ability of a system to perform work on another system. A system is an arbitrary subset of spacetime. Whether a system has energy or not is unknown and unknowable... until it transfers that energy to us... which may or may not be a good thing. Too much energy is going to give us a bad day. ;-) The only reason why people have invented the "particle" thing is because they can't think straight. They always imagine "things" where there are none (the psychologists seem to think that's a remnant of our fears of predatory animals waiting for us in the bushes...). It's the same reason why we invented gods and religions. There is nothing in the sky, but people had to fill it with bullshit. There is nothing in the physical vacuum, either, but people have to fill it to the brim with "particles". Don't be like other people. Be smarter. Let go of the fear of being eaten by things that aren't there. ;-)

  6296. Yes, you can easily calculate the total energy of the system. For a typical wire pair (distance five times wire diameter) the capacitance is on the order of 12pF/m. For 300e6m that's 3600e-12*e6=3e-3F or 3600uF. At 12 V the total stored energy is then on the order of (12V^2)*3.3e-3/2 = 0.26J. Pretty negligible for something involving a light bulb. But that's the fault of the 12V light bulb and the once-on/once-off scenario, not the fault of the transmission line. At higher frequencies and voltages they can transport enormous amounts of power.

  6307. GR does conserve the mass energy of a collapsing star. The lack of energy conservation in the cosmological solution does NOT mean that thermodynamic is violated. The missing elements here is that the cosmological solution creates more spacetime, i.e. it is NOT a closed and isolated system by the usual definitions. The problem has nothing to do with the singularity, either. It stems from the no-hair theorem. A black hole doesn't have observable structure. That causes the entropy problem.

  6342.  @tTtt-ho3tq  Galileo didn't say that the world had to obey Galileo transformations in "Galileo's ship". He simply said that one could not tell locally if ones own rest system is moving relative to some other rest system. What follows from that are two possible solutions: Galileo transformations and Lorentz transformations or, more generally, Poincare symmetry. Galileo didn't push an absolute rest system. That was Newton's personal delusion and it was known to be false at Newton's time. It also didn't agree with Newtonian physics, which is Galileo invariant. At the end of the day the only thing that stopped Galileo from discovering special relativity on the back of an envelope was a lack of algebra. It would take over 200 years to develop those tools and to learn to use them for physics.
    1
  6343.  @tTtt-ho3tq  It's both. The fast moving world becomes distorted. There are simulations of what this distortion looks like for different scenarios. You can experience some of these effects in the Galilean case already. Listen to the Doppler effect of moving acoustic sources. Try to locate a plane based on its acoustic noise and compare to its actually observed position in the sky (that's a bit harder, but can be done under ideal conditions). What Galilean physics predicts is a world with infinite speed of causation. Such a world does not exist. Everything we see are signals of the past. That has "strange" effects on duration and distance.
    1
  6344.  @tTtt-ho3tq  Different observers measure different distances... sort of. In reality there are a lot of false interpretations of the Lorentz transformation around.
    1
  6345.  @tTtt-ho3tq  Yes, there are a lot of ways to measure the relativistic Doppler effect. So what?
    1
  6346.  @tTtt-ho3tq  When a tree falls in the forest it makes an acoustic wave, whether anybody hears it or not. The same is true for relativity. Nature has a complicated set of causal dependencies, whether somebody watches or not. One description of those dependencies is the Poincare group (which includes the Lorentz transformations), but the symmetry group is NOT the physical expression of these symmetries. The way they manifest is more complicated and more subtle than a simple transformation suggests.

  6347. He has aspirations to become one, though. ;-)

  6348. It's not the simulation that suffers from that, it's the system. As soon as we have an almost periodic system that has bifurcation points this is bound to happen. It's not that much different from a Galton board (or a pinball machine): the trajectory has to pass the equivalent of a nail or obstacle, which creates a hard decision point. The effective "gain" in such a system is infinite and the system can not be stable.

  6353.  @ContinuousDelivery  The main problem with FP is readability IMHO. Absolutely nobody (not even the original author) can read an FP program ten minutes after its creation. The main flaw of OO is that it requires a lot of boilerplate that does only one thing: it satisfies the architect's OCD and micromanaging needs, but as soon as you hand that over to the compiler it strips all of it out. CPUs don't speak object language. They only have arithmetic, logic, branch and subroutine call instructions. So in the end your OO code is just program documentation. Why are you spending so much time on a really poor documentation paradigm?

  6354. @ A photon doesn't have a size. It's just a small amount of energy. Energy is not quantized. What is quantized is angular momentum.

The Higgs and pretty much nothing else (there were a few minor discoveries of excited states that were already known theoretically, like the Higgs they pretty much had to exist, and then we learned a lot about quark-gluon plasmas, which are hard to study theoretically). So what did Glashow predict, exactly? That we knew what we were going to find? He was spot on with that. The problem is NOT that we don't know what we are going to find. The problem is that that we DO KNOW what we are going to find. That's a bad place to be in science because one can't learn anything fundamentally new. Unfortunately the scientific method still requires us to look, even where nothing new will turn up. ;-)

  6437. Photons don't have a velocity. They are not objects. A photon is a small amount of energy. It's the amount of energy that the light source emits into the electromagnetic field and it's the amount of energy that the detector absorbs from the field. Both do NOT have to be the same amount of energy! There are simply no "photons" between those events. The human mind just likes to interpolate initial and final states using a classical object ontology. That, however, is not what nature does.
    1
  6438.  @helpme6759  Yes, light, which is the average of many photons has a very well defined velocity.
    1
  6439.  @helpme6759  Light behaves like many photons, but the problem with quantum mechanics is that while it describes atoms, it is not an atomistic theory itself. Thinking about a quantum field as being made of many constituents is a problematic mental model. It is much more complicated than that. You can see this in the differences between the statistical properties of bosons, fermions and classical (distinguishable) particles, among other things. So while there are (classical) states of light, there are many more states that can not be described by a superposition of classical field states (an entangled pair of quanta would be a low-dimensional example of such a state). That's the reason why Hilbert space is so much larger than classical phase space. I wish I could give you a good mental model for what a general excitation of a bosonic quantum field looks like, but I can't. It's way beyond my own imagination.

Dark matter didn't have much of a signature in the community because it is so hard to exclude trivial reasons for it (like dark, cold ordinary matter) that one couldn't say anything substantial about it until very recently. Now we can exclude ordinary matter and THAT makes it interesting.
    1
  6466.  @Bobby-fj8mk  There are dozens of suggestions for different kinds of non-Newtonian gravity. The problem is that none of them seem to work well, either. That line of reasoning is not all that new, by the way. Modifications to general relativity have been under investigation since, at least, the late 1950s, very early 1960s. So far nature isn't very kind to us... every measurement, including dark energy, seems to confirm that Einstein was spot on with his guess. So it's really not because we aren't trying hard enough. We are. But we are also missing at least one major phenomenon that can open all of this up to a wider vista than what we are getting from our observations, so far. And with regards to dark matter... there is still plenty of experimentally/observationally untouched space inside the standard model where it can hide. It will take decades of work to rule out that nothing is hiding in there... and that assumes that the structure of the SM is actually the correct low energy theory... which is may not even be. It's simply a hard problem.

  6476. We know this because quanta are small amounts of energy. Observing a quantum BY DEFINITION means absorbing that quantum of energy. In other words, if we observe a photon at one of the slits, it can not be observed a second time at the screen any more. This reduces the experiment from a double slit to a single slit.

  6481.  @swk327  Inflation doesn't come from money printing. It comes from an imbalance of supply and demand. If you haven't noticed... there is a huge labor shortage and things that used to be plentiful are suddenly missing in the stores. THAT causes inflation. It doesn't matter how little money you print, if something is short in the store, it will be expensive because there is always a buyer who will buy whatever quantity is available at a price that he can afford. If beef was suddenly $10,000 a lbs, the rich would be throwing $1million BBQ parties, even if the Fed would be burning a billion dollars a day. You need to study economics 101. There is no unemployment in the US. The current rate is at 3.5% (which is in the historic lows) and the number of non-farm employees grew by some 233,000. Are you even checking macroeconomic indicators before you write your bullshit? The tech sector is down because it has wasted an enormous amount of money on bullshit like VR and fintech and is now having an investor hangover. Kid, you don't even know the tech sector. China is a late-comer to the COVID game and it is being hit the worst at a time when its population is going into decline. The later has been known for over thirty years (4-2-1-0 families are not good for the labor force) and can't be changed with monetary police, neither by China or any other country. That's dialed in for at least another 30 years. Seriously. Try to learn before you speak. OK? ;-)

There is always substantial risk associated with any business model. Worker-ownership simply ties the resulting workplace insecurity in with additional financial insecurity. If your coop goes down, then not only do you lose your job but you also lose your investment and retirement savings. That is a financially absolutely braindead approach. What you want is diversification. You do not want to own the place where you work. You want to own a broad range of investments and as many of them as possible have to be orthogonal to your line of work. More importantly, you want to have at least one absolutely safe investment. What could that be... hmmm... let's see... something like social security, maybe?

  6501. For a mathematician it's the correct definition, for a physicist it's not. This is no different from the case of dice. A physicist will notice that rolling dice imparts kinetic energy to them and that a dice roll isn't finished until all of that kinetic energy has been used up by the friction with the table. To a mathematician a dice role is a mechanism that selects an element from the set {1, 2, 3, 4, 5, 6}. The exact same thing is true for quantum mechanics. A single measurement to a physicist is an irreversible energy transfer. The quantum of energy that deposits energy, momentum and angular momentum in the detector gives us the necessary indices into the states of the theory. To a mathematician the exact nature of that energy transfer is irrelevant. (S)He merely expects to be told which Eigenvalue/state was measured. That energy and momentum had to change from one system to another is irrelevant.

  6509.  @Jangz_  People fly in the US because there are almost no economically viable routes for bullet trains apart from a few connections on the East Coast. As soon as you have to go the distance (600 miles or more), a bullet train is way too slow. 200 miles or less you are better off driving because you will need a car at your destination anyway. There simply isn't a whole lot of traffic between those two extremes in the US because of geography.

  6510.  @The_king567  He is partially right. I wouldn't say the thing about cleanliness, at least not in the past when smoking was commonplace, even in places where it was officially forbidden. That might have changed since I was there last time. Comfortable is a relative term. For my taste the cars are packed too densely, similar to planes, but while one can tolerate the sardine can feeling if one is traveling at nearly 800kph, it's not that great at less than 300. Not that long distance travel in China is comfortable by any means. The airports are horrible and the only other option are buses... forget about it.

The other half are due to limited vaccination rates in many counties and states since. Counties with good socioeconomics and higher vaccination rates did much better than the average (one third of the deaths per capita). People really brought this onto themselves "in the name of freedom". Vaccination rates in New Zealand are a little higher, but still insufficient. The government needs to do something to get it into the 95% range, at least. My best wishes. Hopefully your son will only have mild symptoms.

When the ensemble of a quantum system is in superposition that's like having an infinite number of dice throws going on at the same time. Are those moving dice in an identifiable state in their outcome space (1-6)? No, of course not. Neither are the quantum systems.

  6537. The same way we know what's inside Earth: we extrapolate from the chemical composition, pressure and temperature what phases of matter we can expect. It's an educated guess. Is it a precise prediction? No, not even close. It will get better over time as we are learning to understand matter at these conditions better and better.

Sounds great, until you realize that the double slit experiment is not even a quantum mechanical experiment and that the actual quantum mechanical description of reality is not based on Copenhagen, but quantum field theory.

There is a good chance that the US is currently supplying these weapons basically at replacement rate, i.e. a few dozen every month. As soon as long range weapons are being used, Russia will have to pull their facilities back, which will make the short range weapons that are currently in use (and available in higher numbers) completely useless.

  6561. @ Yes, that is complete bullshit. If you want to make correct physical predictions about the world then you need quantum field theory. There is nothing else. The Schroedinger equation is neither self-consistent nor physical. It doesn't even preserve energy and momentum. That is what modern quantum mechanics is. Take it or leave it. Philosophy has been bullshit since 500BC. We can scrap that from the minds of thinking people. It's for people who don't care about reality and who don't want to think. What about the statements that quantum mechanics makes about the world is not clear to you? Everything? That's what it seems like to me. ;-)

  6573. Maybe, but most likely not. There is no reason to believe that the notion of "field" is not an emergent property itself, i.e. what underlies reality does not have to be a field, it could be merely something that creates an approximation of fields. We know that exact symmetry is, also most likely, not a property of nature. Symmetry is fragile. It seems to have a tendency to break. It might be possible to prove mathematically that any non-trivial physical situation (i.e. something that allows for a minimal amount of self-interaction) that starts with a perfect symmetry automatically degenerates into an effective one without.

  6575.  @YngvinLion  Wave function collapse is not a thing. The correct way of looking at it is in the context of reversible and irreversible physical processes. Only the irreversible ones are "real". Why? Because a reversible process doesn't leave a long term trace in the world. It comes and it goes. It's forgotten, even by the universe. The intellectual challenge, of course, is to leave the confines of your mental nursery behind. In high school and in early undergrad education even at the university level we are building up this fantasy that the world is reversible. In reality, however, the reversible processes are irrelevant. Hamiltonian mechanics can't tell you how many times the Earth has been around the sun. Only rock erosion can. All we know and learn about this world comes from the very processes theorists dislike because they are hard to calculate. ;-) Similarly the randomness/determinism pair is childish thinking. The primary observation is not that the universe is random. It's that the future is not predictable. 19th century physics could not predict the future any better than we can and not for a lack of computing power. The future is simply not fixed, no matter how hard one looks. So how did they come up with that determinism fantasy? Because after an eternity (well, 300,000 years) of human evolution in an environment that seemed random and hostile, they finally managed to predict one thing: an elliptical orbit of a planet. That was it. They couldn't even do two planets. Today we know that two is already too many. One is it, plus a harmonic oscillator and a handful of other systems. It was that tiny success that lead to the hubris of "determinism". It's not a scientific term. It's philosophical nonsense. So that leaves the question where the universe seeds "indeterminism" (NOT the same as randomness!) from? Relativity. A simple look at a space time diagram can show you that it comes from space-like events. And that is the entire story here.

This phenomenon is just as obvious on other websites like reddit. Tons of literature has been written about how science and the arts in the Soviet Union and China were taken over by peasants who could barely read and write but who had the power of the communist parties in their backs. This is a self-organizing version of that.

Finally even Pluto may have an inner ocean. Absolutely nothing in our solar system points to rarity of potential habitats for life.

Currently the soil is pretty poor, so maybe they should bring in some nice fresh material from the surrounding fields. With a little bit of gardening the entire area could be converted into a sprawling garden in no time. Maybe divert a small stream, or two, flood the remaining basements for the roots of the newly planted trees to have enough moisture? I think we should bring in a gardening expert. That might be more useful than a general at this point. ;-)

  6649.  @physikus1123  You were asking what you are missing. The answer is that you are missing a special relativity class. The reason behind the tensor product structure of quantum mechanics is special relativity.

So, yes, if you want to make a chatbot that produces random unfiltered human-like noise, by all means, go train it on the internet. If you want to produce human-like intelligence, then you have to train it on the K-12 curriculum. Even that won't get you a moral human speaker, though, because morality lies outside of language. It is embedded in the social construct of society. What is and is not taboo is not a list of topics. It's a matter of individual decisions by humans who (have to) live with other humans. The machine is not subject to such limitations.

If they couldn't, then evolution would be left without direction because an individuum that has better adapted behavior would not have a higher probability of survival.

  6689.  @andersjjensen  None of the technological stuff in hyperloop is either hard or new. We have been doing maglev for half a century now, if not more. We can do any size vacuum system you like basically on custom order. The train's passenger cabin is, essentially, a narrow body jet. All the technical criticism of the system is total bullshit. One can talk about economics and demand and that, if anything, is a serious problem for any and all transportation systems. The talk about implosions is just male teenage phantasies gone wild. People had billions of large, evacuated glass tubes at home for more than half a century and very few of them imploded. Yes, one can make thin walled vessels implode. Can one make thinned walled vessel implode that have proper wall thickness and welds and an occasional stabilization ring? No. One can not. At least not without doubling or tripling the pressure of Earth's atmosphere. Unless you are god that's not going to happen. What happens when there is a leak? Nothing. The system detects it and slows the trains down to a safe velocity. What happens when there is a really large leak? The system detects it and slows trains down while flooding the tube along the entire length in a minute or so. Even a shock wave that might spreads from one of your "imploded" sections could only do so at the speed of sound. That's approx. 20km per minute. After that it hits the air that's already in the tube and that's that. That's where things stop. Look, "chemist". I know that you have no intuition for physics and engineering. Why don't you leave this stuff to those of us who do this for a living?

  6704. Yes, the theory does make us expect there to be perturbations, but they would be way too weak to lead to measurable shifts in energy levels or in measurable line broadening.
    1
  6705.  @Darisiabgal7573  First of all, photons don't travel. What travels is the electromagnetic field. What you are describing in the quantum field picture is called a scattering process. Scattering involves an energy exchange with another field and such an exchange between the quantized em field and the quantized gravitational field is not possible in first order because of momentum conservation. It would have to be something like a gamma-gamma-graviton process, which most likely has near infinitely low probability at these energies. The only effective interaction that is left is therefor the classical gravitational field with the classical electromagnetic field and we have measured that, already... it's the deflection of light and radar by the sun in our solar system.
    1
  6706.  @Darisiabgal7573  A photon is not a perturbation of the field. A photon is the amount of energy that the field exchanges with an external system through the electromagnetic interaction. A graviton is the amount of energy that another system exchanges with the gravitational field. The problem is that the classical fields are simply the averages of many such exchanges. That averaging process removes the quantum mechanical characteristics of the underlying quantum field and leaves us with a classical phenomenology. To "see" the quantum nature of the field requires a measurable effect of interactions with one or, at most, a few quanta of field energy. If we need many such exchanges, then the quantization becomes invisible and we are left with the classical field. We know how the classical field behaves. What we don't know is how the process looks like when we have low order scattering like in a process that can be described by two photons, two photons and one graviton out (if that is even a possible process, I am not a theorist, I am just guessing the lowest order based on spin). That process leaves such an incredibly small change in em field energy and momentum that we can't measure it.

  6718. Yes, actually, "we" do know. A "photon" is an irreversible energy transfer between an electromagnetic field and another physical system. It does not have a shape, a size, a power or a frequency. It has an energy, a momentum and a spin. Those three quantities are necessarily present (and related) because of special relativity. Shape, size, power and frequency are classical properties of electromagnetic waves that are formed by many photons.

  6740. First question: are those contracts necessary? If not, then why are they there in the first place? Reliable systems are loosely coupled, hence they don't make a myriad of assumptions about interfaces and they don't try to enforce resilience by hard requirements on other parts of the system.

  6741.  @robertmuller1523  If you have short term goals, then loading your team with contracts is the last thing you should be doing. I have no idea what you are talking about.

  6750. There is nothing to get. The double slit experiment has nothing to do with quantum mechanics. You can tell simply by the fact that Planck's constant doesn't show up anywhere. Quantum effects always come with Planck's constant attached somewhere. And where, exactly, did you see particles?
    1
  6751. There are no particles. Quanta are small amounts of energy. When we detect one we get a "click" in a detector. The "clicks", i.e. when and where these detectors absorb a small amount of energy seem random. We therefor start to collect statistical information (histograms) about them. In the limit of large numbers these histograms become probability distributions. The theory predicts these probability distributions as the product between a wave function, its conjugate complex and a Hermitian projection operator that represents the absorption spectrum of a physical measurement system (the detector). What happens is that almost nobody who makes these videos actually knows WHY the formalism looks the way it looks. For that you would have to read Heisenberg's matrix mechanics papers, where this is somewhat laid out in a language that still relates to physics and that will give you a bit of physics intuition about what is happening. A few years later a mathematician called von Neuman generalized the relatively straight forward physics and math in Heisenberg's papers to an abstract mathematical formalism that comes from functional analysis (the mathematics of linear operators and function spaces). At that point the connection to measured quanta of energy disappears from the textbooks and is replaced with a general notion of "quantum mechanical state". You also lose a sense that this "state" means the state of a quantum mechanical ensemble, i.e. an infinite repetition of the same experiment. Instead it starts looking like as if the wave function relates to an individual system. That is complete nonsense. It was never constructed that way, neither by Heisenberg nor by von Neumann. It's just easy to loose sight of the translation between physical measurements ("clicks") and mathematical formulas.

What somebody scribbled on a piece of papyrus 2000 years ago doesn't give me anything, unless it contains a truth that is independent of space and time and that would be just as valid if it had been written yesterday. So, no, I generally don't give a frell about what Josephus wrote or anybody else.

  6781. One can derive the structure of quantum mechanics using basically the Kolmogorov axioms and by dropping the requirement that the probability distribution is real valued. Plenty of people have done it with slight modifications in the basic assumptions as far as I know. I don't find these derivations particularly interesting, though, because the structure of quantum mechanics is entirely free of actual physical content. One needs far more than that to arrive at physical predictions, which brings us to axiomatic quantum field theory. That is, if anything, the real deal, but I don't know enough about it, yet.

For events with spacelike separation both event orders ("A before B" and "B before A") can be observed by different observers.

  6826. One has to be very careful about such claims. Diluting a substance with very high dilution factors is actually more difficult than the homeopathy supporters claim. First of all the dilution process has to be carried out properly, controlling for surface effects and assuring complete mixing and it has to be monitored constantly with analytical chemistry. More importantly, the solvent and all equipment have to be free of contaminants. I doubt that homeopathists are doing any of that properly, so what you are really getting is not "nothing", but it is whatever contaminants exist in the facilities and in the solvents, which is probably worse than what comes out of a proper pharmaceutical production process that is strictly monitored.

  6827. That's because he doesn't know how it works, either. It doesn't take ten minutes to explain quantum mechanics. A single sentence is enough: "Quantum mechanics is the theory of the unitary representations of the Poincare group.". If you want to unpack this: the Poincare group is the symmetry of spacetime: translation symmetry, rotation symmetry and relativity, i.e. all physics is independent of the state of constant motion of the system. Unitarity is the property of ensembles of many identical but completely independent experiments to have equally many experiments in the final outcome as in the beginning, i.e. we are not losing any experiments while we are performing them. If we prepare the same experiment a thousand times, then we get a thousand results. Quantum mechanics is simply the mathematical consequence of these two assumptions.

  6833.  @rustyosgood5667  In case of photons the electromagnetic field. In case of electrons an electron field etc.. In totality these fields form the physical vacuum. At low energy they are separable, at high energy they are not. Once they separate and weak measurement conditions are applied, emergent qualities like classical matter and its "paths" are being recovered. There is not nearly as much "magic" here as poor explanations on the internet suggest. It's really not all that much different than gas/liquid/solid phase transitions. Gases take in any volume they are given, liquids condense to near constant density and solids can have lasting shapes, which neither liquids nor gases produce. The physical vacuum is merely the next quantum step beyond the usual "phases of matter" classification.
    1
  6834.  @rustyosgood5667  Yes, the theory has all of these. Nature doesn't, of course. It's all one vacuum, we are merely separating these observations to make the physics easier to digest for humans. That's what science does. It reduces to make things easy enough for the human mind. It already did that in classical mechanics, you just didn't notice. Non-physicists rarely have that level of structural insight. :-)

The question is... why do you want to be confused about something trivial? Are you looking for some kind of atheist religion here or a god of the gaps? It's not here. Quantum mechanics is a trivial consequence of special relativity and how it can be derived from first principles was basically known since 1932. :-)

  6868.  @TheTruthOfAI  If he didn't infect anybody then everybody around him got lucky. Luck is never a strategy because it always runs out and it does not exist on average in the first place. The problem with COVID-19 is that many people are infectious before they notice the symptoms. This was clear very early on in the research literature (May 2020, if I remember correctly? Don't hold me to it, I don't feel like looking it up. That detail doesn't matter.). This also means that testing the symptomatic is simply a feelgood measure. By the time most people got tested and they got results back, they had already infected somebody else. Testing basically misses the window of opportunity by several days (It's the same for the flu, by the way, that's why your doctor usually won't even test you for flu, even though those tests have existed for a while). The only measures that work with COVID-19 to suppress the spread are pre-emptive. Masking works for short contacts (but most likely not for people who have to spend eight hours next to each other, including kids in school). Vaccination reduces the number of infections and lowers the rate at which the disease spreads, but only in homogeneously vaccinated groups. The only thing that is 100% effective is strict social distancing and it's the one thing that people are really not willing to do. In other words... the virus is evolved to use human behavior to its advantage.
    1
  6869.  @TheTruthOfAI  No. Like I said, the only 100% effective measure is social distancing. China basically forced all the people in Wuhan to stay indoors for twelve weeks. That's a very extreme measure that worked even without vaccination. If we combine vaccination with effective social distancing and masking, then we can get away with less restrictive measures. Much more effective masking, e.g. with battery powered respirator masks that are far more protective than either cloth or surgical masks (while being far more comfortable) would work. We have all the solutions. What we don't have is the will of the population to apply them. People are trading a misguided sense of "freedom" for a life with a deadly disease that will kill many more millions over the coming years.

  6875. Yes, we invented the theory of quantum mechanics. Like all physical theories it is a story to describe the world in rational and quantitative terms. It's a story that works well. How it was invented is a slightly complicated affair that, if you really wanted a deep dive, would require you to read a lot of very, very confused papers. At the end, however, you would find that none of this confusion is necessary. One can derive quantum mechanics rationally from a few axioms in maybe a dozen pages of almost high school level math. It's not complicated... but hindsight is always 20/20.

  6877. It's simply a mathematical fact that one can't extrapolate scattering data much more than an order of magnitude beyond the scale for which very good statistics exists. In case of the LHC that regime basically ends at the TeV range. Beyond that we are literally blind, so even a non-discovery at 10TeV would be a discovery.

  6890.  @WayOfAges  A quantum is a small amount of energy, momentum, angular momentum and charge. More precisely, it's the smallest amount of angular momentum and charge that physical systems can exchange. A quantum process consists of the irreversible emission or absorption of one of these quanta by a source or detector system. If quantum processes are independent of each other (i.e. none of them can be predicted based on the results of all the others), then their statistics can be described by two formulas which are usually called "the Schroedinger equation" and "the Born rule". Both are based on either matrices or linear operators and they can be derived from Kolmogorov's axioms and a few assumptions about the physical interpretation of the linear algebra. That's it. The remainder is basically just math that uses linear algebra and linear operators. For the purposes of physics it's not much more complicated than what we are teaching in high school.
    1
  6891.  @WayOfAges  I am calling the people who can't explain quantum mechanics this easily unintelligent. A better phrase would be "intellectually lazy". These facts about quantum mechanics have been known for a long time. OK, the derivation directly from Kolmogorov might be only thirty years old, or something. I don't remember the earliest paper in which I saw it being done. Maybe it was from the 1980s, which would put it into the 40 year category, but I wouldn't rule out that there are much earlier papers that I simply haven't seen, yet. I am not a science historian and I won't spend weeks or months in the library to dig up some obscure paper from the 1940s that only three people have ever read. So, yeah, my own QM 101 professor was in that category of "intellectually lazy teacher". He didn't care to explain what it was that we were doing there. He just threw the linear algebra at us without any physical connection to the real world. He could have known better, IF he had read the literature that existed at the time. This problem is endemic in the physics community. Professors who are being tasked with teaching a subject are usually very good at their specialties and crap at everything else (as you might expect). Quantum mechanics is not even a specialty. It's a general framework that is being used in many actual physical disciplines like atomic and molecular spectroscopy, nuclear physics and solid state physics. Everybody knows how to use it but almost nobody knows WHY it works and WHY it works the way it works. That almost nobody knows, however, has nothing to do with it being unknown. It's known extremely well because it is extremely trivial. It just happens that nobody teaches these trivialities and the language that we are teaching, even in university, is basically 100% false. The math is all correct, but the way we are talking about the math is about as misleading as one can make it. That's a phenomenon of science history.
    1
  6892.  @WayOfAges  It is a fact that there is no complexity here. There are only bad teaching habits. Quantum field theory and general relativity, those have serious complexities. QM doesn't have any of that. We could teach it in high school and one day we will. Nobody in physics profits from any of this, either. Most physicists just don't care to explain it correctly. I just did. It's up to you whether you actually want to listen or not. My guess is you won't. And that, my friend, is YOUR intellectual laziness at work. ;-)

  6893.  @WayOfAges  "Quanta are small amounts of energy.". It doesn't need much superiority to remember that. You just have to actually listen to what you are being told in high school.

I gave you the correct answer in my second reply without talking down. You weren't listening and gave me some p*ssed off reply. That's a fact that only you can change. I can't change it for you. If you have a question I will try to give the correct physical answer. If I don't know the answer then I will tell you. I do have an answer for most of the trivial questions people are asking. That does not mean I have all the answers. The most simple question about quantum mechanics that I can not answer as of today is this: "Why is angular momentum quantized?". I honestly don't know. I suspect that it's something non-trivial in special relativity but I can't give a simple intuitive argument why it has to be this way. I am still searching for a way how one can understand it from first principles. Maye I need to read a few more quantum field theory books. Maybe there is a paper that I haven't seen, yet, but it is a fact that as of right now that's still a bare spot in MY knowledge about the world. See how easy it is to admit that you don't know something? I can do it. Please try to learn this technique yourself. It will make science far more enjoyable for you.

  6948. If the increase in the value of a property outweighs the loss of the rent, then not renting out the property does make sense, especially since a used property deteriorates quickly and needs constant and expensive upkeep. One can make similar arguments for all of the above. These are not "beliefs". These are simply counterintuitive economic realities. Should these realities change "one day", then the people who will be facing the new realities will simply adapt to them. If "one day" a toaster made in America will return a decent profit, then there will be a toaster made in America the next day. Until then there simply won't.

  6954.  @susansibley8093  None of the people in my family who had Pfizer, Moderna and a booster had COVID-19 even once. The eight antivaxxers in my family had it twice now. A couple who had sinovac had it three times. I would consider the Chinese and Russian vaccines as useless, indeed. If you look at the overall statistics, vaccinated and boosted people are far less likely to become vectors, they are far less likely to be hospitalized and they die way less often. Vaccines work great. At this point COVID-19 is a disease of the filthy unvaccinated folks. :-)

  6956. Xi is also not laughing. Putin was supposed to make short process of Ukraine, which would have set the stage for an invasion of Taiwan. Instead Western weaponry and military doctrine turned out to be far less decadent and far more deadly than the Eastern planners had imagined. The economic consequences of Russia's actions also came into razor sharp focus. The West is more united now than it has been in decades. Putin's cozying up to North Korea is strengthening the ties between South Korea, Japan and the Philippines. The world is steeling its muscles and pointing its spear tips towards Russia... and China. What should have been proof of a weakening of the West has become the opposite and it is making a laughing stock out of Xi and his imitation Mao political beliefs.

  6964. None of it. Quantum mechanics is a very simple theory, you are just not being told the actual facts about it. What you get to see on the internet is a half-baked phantasy that was popular around the early parts of the 1920s. Real physics had moved on from that state of ignorance as early as 1928/29. The modern picture was developed around 1948 to the mid 1960s. Since then the theory has seen one experimental confirmation after the other in the energy range below 1TeV. There is very little doubt that it holds for much higher energies just as well (experimentally that's confirmed by cosmic rays). So if you have a problem with it, then that problem is entirely in your mind.

  6970. Why is statistical independence hard to test? You are simply calculating correlation functions and show that for large numbers the correlation goes to zero. It's the usual assumption of the transition from frequentist statistics to probability theory. EPR doesn't show non-locality. It shows non-separability. The only shame here is that it's 2023 and people still can't differentiate between a property of physical space which is real and a property of Hilbert space, which is a mathematical abstract. Real space can kill you if you fall from a cliff, but nobody ever fell to their deaths in Hilbert space. Seriously, folks... you need to start paying attention in kindergarten, when we explain the difference between real things and abstracts to you. ;-)

  6971. A measurement does NOT make the "probability" of an outcome 100%. That is absolute nonsense and folks who are speaking on a math channel should know better than this. A measurement simply produces one physical outcome. If we tabulate many such measurements, then we get frequencies and if we then imagine that we can take an infinite number of measurements, then we get probabilities through the law of large numbers. The individual measurement, however, does NOT change such probabilities at all. It has an infinitely small influence on the probabilities by definition.

The 1864 law probably even made sense back then because an abortion procedure at that time was very dangerous to the woman and was mostly carried out by non-professionals who did not care about the life of the woman at all.

  6995. Complex numbers aren't describing particles. They are describing rotations of representations of the states of ensembles.

  6996.  @idegteke  Nothing is made of ensembles. An ensemble is the abstract notion that one can repeat the (exact) same experiment an infinite number of times. In practice that is completely impossible, but many physical systems (like a thermal light source, for instance) behave very similar to such an ensemble and can be approximated by one. Other systems (like a human body) can not be. The ensemble description is simply not a valid approach to every system, but it is valid for many important systems and that is why we are using it in quantum THEORY.

  6997.  @idegteke  Physics is 100% dependent on observations. Just because you didn't take the time to learn enough about nature doesn't invalidate either nature or its scientific descriptions.

Don't make me put you into the same bin. You are getting very close.

  7012.  @janellegrace5815  I am tired of people who treat reality like it's a religion. Just because Marx and other people wrote something over a hundred years ago does not make it true and it does not make it the last word. We have tried socialism (as in the control of the means of production by the government). Socialist states have built slave labor camps. Hence socialism is NOT foreign to slavery. There is undeniable historical proof of that. Hence Marx was wrong. Now, we do know how slavery works. We knew this way before Marx. We didn't need him to elaborate on this. It works by dehumanizing humans. It strips them of their sentient quality to justify their inhumane treatment. It did that, even in theory, at least since Aristotle who wrote: "Where then there is such a difference as that between soul and body, or between men and animals (as in the case of those whose business is to use their body, and who can do nothing better), the lower sort are by nature slaves, and it is better for them as for all inferiors that they should be under the rule of a master. For he who can be, and therefore is, another's and he who participates in rational principle enough to apprehend, but not to have, such a principle, is a slave by nature." Aristotle says nothing about capitalism here. He simply entombs the right of the strong to enslave the weak as a matter of natural law. The bible does the same. It took humanism to declare these points of view immoral and reprehensible. Did socialist rulers care? Of course not. They exerted brutal power under the disguise of serving Marxist ideas (incorrectly or not) and they established slave labor. Now, you wanted respectful discussion? There it was. And it's gone in a flash because I can tell that the next thing you will pull is a no true Scotsman fallacy. Take care.

  7024. Here is the problem if you are that rich: nobody can ever love you for who you are or even for what you do for them. There is not a single person in the world who can cut out of their brain that the guy has a net worth of $400 billion. It's not possible. He could literally buy a new skyscraper for one of his "girlfriends" every day for a whole year. Well, actually, he probably can't because there most likely aren't that many buildings worth a billion dollars in the world for sale. So what does it mean if he buys them a 10 carat diamond ring? Or a $10 million necklace? It means absolutely nothing. He might as well have bought them an ice cream cone. If the guy on minimum wage gets his girlfriend a measly $400 ring... that means something because he had to save up for months or do some jobs on the side. Elon does something, it's absolutely meaningless, whatever it is. So that leaves the charm... which he doesn't have. People on the Asperger's spectrum are not known to be particularly charming. No amount of left brain action can make up for that. So where does that leave a billionaire like Musk? It leaves them in absolute loneliness. You can tell that he is trying to fill it by trolling the entire planet. One has to wonder how that works for him. (And this is not to say that he can't find people who will "entertain" him for the money or the fame. There are plenty of those, of course, but that's not love. That's just another form of greed in action.)

  7055.  @kellyscarolinagarden  I get it. My parents had a 27 year old Honda that drove just fine and that they didn't want to give away, either. That's emotional attachment. Is it financially rational to fix these things up? No. A car is designed to wear out and it wears out. Sometimes we get lucky and the use pattern leads to longer than average life, but in general it makes more sense to invest in a new car at some point. Putting $400 in a repair may make sense, but I would definitely draw a line at $4000. That's 10% of a new model and was probably more than what the car was worth at the time.
    1
  7056.  @kellyscarolinagarden  Good point. If you can tie the time over until you can buy an EV that suits you, then the investment may make sense. With the current cost of used cars the strategy of replacing a very old used car with a newer used one would not work well, either, in this case. Don't know what the rates for car loans are these days, but if you have to do financing, then there are probably no really good options right now either way.

  7057.  @erik_dk842  I don't own an EV, yet. I have an aging car that will replacement at some point, unless I go first, of course. I am already kind of worthless in the used human market, myself, and while cars can be repaired almost indefinitely, humans can not. ;-)

  7058. OOP doesn't make code readable if you use inheritance a lot. In that case it actually disperses and even duplicates code. This is a big deal if you have to fix a problem with a method in one class because now you also have to check the code in all derived classes that have a modified version of that method. It's basically the same problem as with forking, just internally to one program.

So either your grandfather is not responsible for bringing one of your parents in this world (and you just randomly appeared with your grandfather being correlated to some observers) or physics is not relative. We do not have any evidence for either of these conditions being violated. That makes FTL fiction at this moment.

  7072. You can trace back the "why" for OOP to a time when CPUs had very little memory. It allows the compiler to re-use the same function from the base class for all derived functions and therefor minimizes the memory footprint of the program. The idea behind C++ is very well documented by Stroustrup in his book: he was trying to explore how one could move as much effort from run-time to compile-time without giving up as little flexibility as possible. That, too, is basically all about optimization. There are no mysteries here... you can find all of that documented in the literature.

It was never true, John Q Public just doesn't want to understand how quantum systems really work because it is... complicated. John Q Public doesn't do complicated. He likes to do "utterly false", though, as long as it's simple.

  7086.  @daz501h  Of course people can be studied. They can be experimented on. Unlike with nature, however, the outcomes are not reproducible, which means that your experiments are not producing facts but just the random outcome of the day. Now, if you take the time to read a few psychology journals, then you will find that most psychologists don't experiment and the ones that do do it extremely poorly. A lot of articles are more along the lines of a new Dr. Freud announcing his personal theory of the human mind.

  7091. I don't know what you mean by programming concepts. Pointers and references? Arrays? Lists? State machines? These are all logically necessary concepts. A person can point you to the mountain, which is useful, even if nobody can move a mountain. An array and a list perform differently on different kinds of operations. Inserting an element into an array is an expensive operation. In a list (even in an ordered list) it can be cheap. Retrieving an element from an array is cheap, retrieving an element from a list can be expensive. General control flow is unpredictable, state machines are completely predictable etc.. No language can get you around these differences. You have to understand them in some level of detail first, if you want to be a good software designer.

  7092.  @NStripleseven  Data that isn't mutable isn't very useful to begin with. All of computing is about the question "what shall we do with data". This isn't language dependent, either. One can make C programs that are "safe" with regards to constants, if that is your concern. All you have to do is to use the memory management unit and declare a constants segment that is read only. Any attempt to write to it will lead to an abort. Is that "safe programming"? No. That's just the train of thought of a poorly functioning person with OCD. There are, unfortunately, too many self-anointed programming geniuses who are suffering from that very condition. They are obsessed with not writing to memory areas that "shouldn't be written to". That, of course, was never the problem. The problem was always to write THE CORRECT values into areas that should be written to. ;-)

    1
  7103.  @K.A7287  Your problem is still the same. You don't understand what is in superposition: it's the wave function, which is an ensemble description. The quantum mechanical ensemble only exists in your mind. It doesn't exist in nature. Not only that, but neither does nature have a "position" property. Position is the classical average of many weak measurements. It's not something nature cares about to begin with at the fundamental level. That should be obvious from Noether's theorem. There is no symmetry that leads to a "position conservation law".

  7104.  @K.A7287  There are no particles. Nobody has ever seen one. We try to teach even in high school that "quanta" are small amounts of energy. Entanglement is simply the correlation between energy transfers in different parts of a system. What causes entanglement? The symmetries of the system. What's a symmetry? It's the absence of a symmetry breaking mechanism. So... entanglement is something that happens because something else doesn't happen. ;-)

An electron track looks different than a muon track looks different than an alpha track looks different than a gamma track... even on visual inspection of a bubble chamber or cloud chamber photograph. The electronic readout of our modern detectors differentiates these different kinds of interactions even better. Just because you don't know what you are looking at doesn't mean that people who have studied high energy physics don't know. Are you trying to appear as dense as a Uranium 238 brick on purpose? ;-)

Trump simply needed a political cover himself because he is basically reversing his promise to his own voters about not involving the US further in Ukraine.

    1
  7145.  @simian_essence  My best bet would be on much stronger magnets. ITER, and this I believe to be a valid criticism, was conceived ten, fifteen years too early and it is based on the 12T technology that seemed like a safe bet at the time. Once the field is set, the only way to achieve their goals was with enormous plasma volume, so they had to settle on a dinosaur. Machine cost scales, at least, with third power of size, if not faster, while fusion power density goes up with the fourth power of the magnetic field, so the volume bet is an absolute loser in terms of R&D, construction and operating cost. It's a pity that they didn't wait a few more years and didn't invest in magnet R&D first and foremost. MITs PSFC group has a few words to say about high field magnetic confinement fusion. It's well worth reading, even though some of it also comes with large grains of salt, of course. Field alone won't do it, but it's the right start.

  7149. The Schroedinger equation is not part of a complete theory. It's a non-relativistic single-quantum approximation. The only "complete" theory is quantum field theory, but you would not try to use it for atomic physics because it entails way too many non-atomic physics effects that are hard to separate out in the way the theory is formulated. Instead atomic physics, like nuclear physics is done with a series of ad-hoc approximations that can be justified both from a QFT theory point of view as well as from an experimental confirmation angle. They are, nonetheless, ad hoc approximations.

You can easily see this in Heisenberg's work, it's a bit harder to notice if you are dealing exclusively with the Schroedinger equation.

  7160.  @sundhaug92  If you are on microcontrollers knowing how to set up the MMU is, unfortunately, a requirement, or, at the very least it is very helpful. I would, of course, not reinvent the standard libraries or write a file system library from scratch. That is completely pointless. I did write a specialized bare metal scheduler in a day once. It worked like a charm and was 100% stable. Why did I do that? Because there simply wasn't enough memory on that microcontroller to fit an OS in for that purpose alone and even if there had been, reading the documentation would have taken longer than implementing that one piece of code that I needed myself. One has to know where to put an end to reinventing the wheel, though. In the microcontroller world many low level libraries and "drivers" are hopelessly overcomplicating things because the programmers of those libraries are trying to satisfy a lot of different needs with an unsuitable approach. Hardware libraries can not replace operating systems, no matter how "universal" they are trying to be, but it seems that is what many coders of those libraries are being asked to do. In my experience bit-banging the hardware registers very often solves problems much faster and more reliably. So, yeah... shaving that code is actually a viable approach. In moderation. If somebody needs a file system, real multitasking, dynamic memory allocation and inter-process communication in addition to an ethernet library, then the gloves are off. That is not worth reinventing.

  7168. It's not clear that quantum mechanics is incomplete. It's a theory very much like thermodynamics or statistical mechanics that follows from first principles. What is certainly completely open is the collection of fields that nature choses to implement on our scale, which is generally called the standard model of high energy physics. What is also under great consideration is the correct mathematics for field quantization. The way we calculate quantum fields right now is very byzantine and it leads to a lot of technical difficulties that have to be dealt with individually. There are some ideas out there how all of these technical problems could be greatly simplified, which would open the door to quantum field theory for a much larger audience than the comparatively few theoretical physicists who have the pain tolerance to deal with the current math.

  7198.  @andrewbagshaw3095  Dude, YOU wrote a diatribe about the cost of homes. That's simply supply and demand and "in the West" as you said it, which in the US means California and especially California oceanfront properties, supply is very limited. There is only so much buildable shoreline and even behind that there is only so much land that people want to live on. And if you want to talk about Australia, I have been there as a tourist, there is also only so much land that people have the hots for. As much as I liked the outback and Alice Springs for a day or two, I would still prefer a pad in Sydney, Mate! And that also means that if I could afford one, I would buy it at any price that is within my reach (don't worry, it's not within my reach). I have no idea what any of that has to do with child labor in Bangladesh and neither do you. Are we cool? Now, with regards to the US, the problem is not the cost of housing. The problem is that the value of manual labor is constantly declining. There is nothing anybody can do about that. Mechanization is marching along at exponential speed. What took ten people in the past can today be done by one or... none.

Why in the world should I worry about that? If I had been desperate to be rich, then I would not have done science but finance or something. I didn't vote in like thirty years. Not because I don't care but because I was usually working in countries around the globe were I didn't have the local voting rights. I am a global citizen. That's far more interesting than to vote some local idiot for mayor or some federal idiot for president. Before that, while I still had the voting rights, I was living in voting districts where my vote made no difference. In one the social democratic party won all the time, in the other it was always the conservative party. Whether I added my voice for or against the surefire winner didn't matter. That is how democracy works. Even perfect democracy works that way. So, kid, what is wrong with you? If you want to change the world, then get off your ass and do something USEFUL.

  7204.  @andrewbagshaw3095  Both parties have the same policies? OMG? There is no party that caters to your personal flavor of crazy, kid? The sky is falling, and the end is near! :-) What I was describing is that I didn't have voting rights for the past 30 years because I was never citizen of the country that I was living in. You clearly didn't listen. You are completely caught up in your own little phantasy. :-)

  7212. In 2016 federal customs revenue was $35 billion. This year it's $100 billion. After these new Trump tariffs it will be $120 billion. This has nothing to do with border security. Trump simply needs money for tax cuts to his billionaire friends. By the end of his second term Americans will be paying $500 per year per person in hidden taxes that will benefit exclusively the super-rich. ;-)

  7225. No, what they mean is "local realism". Local realism is mostly just a newfangled term for "Galilean physics" where everything was determined by the physical values in every given spacetime point. Local realism basically went out the window with special relativity, already, the lesser minds just didn't notice it.

  7248. NATO countries have strong militaries. Russia has shown the world how far a strong army gets you against a weak one these days: roughly 100-150km into the weak army's territory. That's it. After that the easy going stops, no matter how strong you think you are. Russia does, by the way, know this phenomenon extremely well: it stopped Germany cold in WW II. The Germans never penetrated Russia any deeper than the Russians are penetrating Ukraine, right now. Defense in depth is extremely powerful.

  7259. Nobody benefits from either rail or no rail. Rail is not a viable solution in the US. I have been commuting on a very expensive and quite luxurious local rail system in the US for years. That was me and one more person. It would have been cheaper for the community to call a limo for the two of us than to operate those 100 tons of steel with electric motors. ;-)

  7261. What is true for fusion is true for fission of all sorts: it's too expensive. The thorium reactor only give us more fuel, but then, we don't really need a million years of expensive fission energy. We will need a couple hundred years of dirt cheap solar and wind energy. We are deploying hundreds of GW of both annually with exponentially rising investments. In comparison, everything else is a losing proposition, economically speaking.

  7286. Time is not a dimension. Time is that which the clocks show. The diagram basically relates clocks on Earth to clocks on Vega to clocks on the STL ship. The problem is that clocks order causal events by assigning time stamps to them. The only way you can have FTL is by allowing these time stamps to change almost randomly. So what is a causal event for one observer is not one for the other. If you make a movie out of this then you would actually see the frames in the opposite order, i.e. FTL could make it look like somebody on Earth could predict a supernova that hasn't happened, yet. Or predict next week's lottery numbers... which would make all kinds of games of luck completely irrelevant in an FTL universe.

  7289.  @dimitrispapadimitriou5622  Dudes, there are no probabilities in quantum mechanics. Probabilities do not satisfy any conservation laws. It is true that quantum mechanics is a solution to Kolmogorov's axioms, just like probability theory is, but it is a solution that satisfied Poincare symmetry, which probability theory does not. And if you look carefully at what Kolmogorov posits, it doesn't posit anything relating to randomness and probabilities. It only requires INDEPENDENT choices from a base set.

    1
  7297.  @dmknght8946  No. Truce? :-) I do agree, by the way, that Linux is in a crappy place. It's not that easy to get commercial companies to support it. That has serious reasons that an experienced business person will easily understand. The problem does not have an easy solution. Microsoft and Apple can simply throw their weight and lots of dollars around. That route is not available to the Linux community, they have neither. What they could do (but won't because it violates the sacred ideology) is to make ONE high performance Linux distro for exactly ONE hardware configuration. That's what Apple does all day long and look how well it works for them. But then, Linux is not Apple, so why should it do the right thing, right? :-)

A the same time these companies are also suffering from a lack of university educated employees. The American college system is neither here nor there.

  7313. Anger does not a good advisor make. We all understand how Ukrainians feel. We would feel the same way... but feelings don't make facts. The fact is that SpaceX is 100% controlled by the US government as far as its services to foreign governments go. If the US government says "No.", it's a "HELL NO! And don't you dare unless you want to get a 5am morning visit from the FBI.".

  7314. The problem is not that. The problem is that whenever somebody talks about non-locality, what they really mean is non-separability. The world is perfectly local for all we know, but it's also 100% non-separable. What's the difference between the two terms? Locality describes properties of physical systems in real space. Separability is about the properties of their mathematical description in Hilbert space. There is no mistaking one for the other. Real space can harm you, Hilbert space is just a mathematical abstract. The two do not even share the same dimensionality. It's mind boggling that people can't differentiate between the two.

  7353. You can get such a shock. The magnetic field just has to change fast enough and it has to be strong enough. The field coils of a modern MRI machine are strong enough and they are switching rapidly enough to produce induced electric fields that can be felt. If they were just a tad stronger, getting an MRI scan would quickly become a very painful affair. It simply takes high powered equipment to get to the required voltages. A small battery and a piece of wire won't do. One could probably do it with a car battery and an old transformer, if the windings are reconfigured just right. Alternatively one could try to spin a strong rare earth magnet at several thousand rpm (possibly 10,000 or more... not an easy thing to do safely, flying magnet pieces definitely hurt, even without induction).

  7354. Sean Carroll is utterly disingenuous about physicists not asking questions about the meaning of quantum mechanics. We do understand the meaning of quantum mechanics perfectly well - in relativistic field theory. It just happens that only very few physics students take classes in quantum field theory and high energy physics. The majority of physicists don't need that level of detail for their work. Most of atomic, molecular and solid state physics can be done happily with the non-relativistic pseudo-theory that people know as the Schroedinger equation and the Copenhagen interpretation. But that's the state of physics from 1926/1927, i.e. it's almost 100 years old by now. It was not self-consistent back then and there is no way to make it self-consistent, no matter how much clueless people are trying to doctor around it with pseudo-scientific and pseudo-philosophical band-aids. Anybody who really wants to understand what makes the world tick will have to take the plunge and spend five years of their life on learning quantum field theory. That's all there is to it.

  7360. And just how many times did you use that feature? The universal tool of CS are algorithms and data structures. If you need an array that can be indexed by the names of fruits, you simply use a dictionary in Python. The reason that nobody writes in Pascal is because the basic language was insufficient to get work done, so you needed extensions and dialects like Delphi.
    1
  7361.  @anthonynorton666  That's the point. You don't need to build stunts like an ordinal set index into the language. A dictionary library or class will do the same thing just fine and you get to chose your implementation depending on the actual structure of your data.

  7362.  @anthonynorton666  VBA has, of course, the same problem as Delphi: product lock-in. C is C is C on every machine (up to hardware dependent issues like endianness and word length) and always sufficient to do everything that needs to be done. One can say the exact same thing with regards to lock-in about basically every API Microsoft has ever published (and iOS and Android and so on), not to mention Linux library hell. All of these things are evil and should be avoided. But then... today's frontend-database-backend process is basically just Dante's Inferno applied to software development.

We either have to start punishing bullshitting (seriously) or we have to change over from democracy to some kind of meritocracy where those who are listening to bullshit lose their votes. Eventually the transition from humans to transhumans will make this problem go away anyway.

  7365. Did an of you notice that Bechtel is also a contractor of the US military? Now, imagine you want to procure some military infrastructure that you don't want your adversaries to know about through an explicit Congressional line item in the budget. You may give your military contractor a cost plus contract on some civilian use project that "magically" happens to have enormous cost overruns. Congress is happy because all the line items are accounted for. The military is happy because it gets something that it wants to use in secret and the intelligence agencies are happy because they can hide what it is that they are really doing with this new capability. Or did you really think that the cold war and the space program overlaps (both peak spending and later program cancellations when the cold war became less intense) are completely uncorrelated? Did you also notice, by the way, that Bechtel is privately owned? It is not subject to public accounting reviews. It can move money around internally all it wants and nobody can say a thing. :-)

  7375.  @RFC3514  There is no random noise in quantum fields. That there can't be follows from the fluctuation-dissipation theorem (also second year undergrad physics). Random systems also violate basic physics like energy and momentum conservation. Quantum mechanics does none of that. What quantum mechanics does is to introduce an element of UNCERTAINTY. We simply can't tell when the next quantum event will happen and where. THAT is what follows directly from relativity. Why? Because in a relativistic universe the local future depends on physics which in the local present happens in a space-like separated volume of spacetime. Here is a simple example: a Mars probe detects a radiation event on Mars, RIGHT NOW. We have to wait for ten minutes (that's the time the radio signals of the probe take from Mars to Earth) before the radio signal arrives. At the time it arrives, though, it is a completely new and unknowable physical event. Nothing we can do here and now can predict what that signal from our Mars probe contains. That unpredictability drives quantum mechanics. You can formalize this with ensembles and Kolmogorov axioms and then (somewhat unexpectedly) you will find Pythagoras in your calculations. Pythagoras leads to scalar products which are invariant under unitary groups... and suddenly you got the entire matrix mechanics thing popping up in a calculation that was all about statistically independent individual events. THAT is how you get RATIONALLY to quantum mechanics. It's pretty boring, actually, except for the Pythagoras bit. ;-)

It was a pretty big theme in the late 1980s or 1990s, if I remember correctly. A simple example is a highly magnetized Rydberg system.
    1
  7389.  @NyscanRohid  There is no measurement problem. Every day physicists are doing trillions on trillions of quantum measurements. Every single measurement is the transfer of a small amount of energy from a quantum system (like an atom that sends out some light) to the measurement system (a photodetector). All of this is covered perfectly fine by the high school textbook definitions of energy and systems. As you can see, there are always two systems involved in a measurement. If you try to lump both systems into one (which one can, due to the definition of "system" as "a partition of nature by a physicist"), then the energy transfer process simply can't be defined and we can't talk logically about "a measurement" at all. What people call "the measurement problem" is the search for nature's equivalent of the second "measurement system". It's all around you. It's the physical vacuum. If an atom sends out light, then that light travels at the speed of light away from the location of the atom. Since nothing can be faster than the speed of light, the energy in that light is entirely lost to the local "atom system". The atom can never get it back. That irreversible loss of energy from the localized system to the infinity of space, that is the reason why nature constantly makes measurements on her own. When was this known? Very early. You can find this explanation in von Neumann's seminal book about the mathematical structure of quantum mechanics. It's in chapter six, I believe. The book was published in 1932, but you can find similar language in works of Heisenberg and Bohr a couple years earlier, around 1927 to 1929 or so, if I remember correctly. Its basically contemporary knowledge with the Copenhagen interpretation. Most modern textbooks aren't discussing it because it is such a triviality, but that doesn't mean that we don't understand it. It just means that the average student never gets to hear this explanation.

  7390.  @berserk9085  It's not even wrong. So would every workable model of quantum gravity be. It's not a problem of string theory that it can't be tested. It's a simple empirical fact of life that if gravity is quantized (and why would it not be, at least in some sense), then it doesn't leave any measurable signal in any of our current instruments. There will be rapid progress in the field as soon as such a signal can be detected with better instruments. Until then the theorists will simply keep throwing black darts in a tunnel at midnight at a black target (or just an imaginary one).

It should not make you want to have a romance with the performers. Those people are simply doing their jobs by creating an emotionally gripping product. One thing has nothing to do with the other. People who can't differentiate between the two have a psychological problem that needs to be addressed. You do have a point that pitying them does not address the problem.

  7398. Photons don't take any paths at all. Photons are the amounts of energy that gets absorbed by a detector at the end of the experiment. That energy doesn't have a path.

We tried to teach you that in classical mechanics in high school... but you (like all other students) weren't paying any attention.

  7408.  @Thomas-gk42  Hard determinism means predictability. The first necessary assumption for that is that there is a theory that can reliably predict everything if we have enough information that we can stuff into it. That is mathematically provably not true. There are no such formulas. The second assumption is that you have all the information that such a formula would need. That is physically provably not true. So you are striking out on two necessary conditions for determinism. Look, determinism was always false. It was an overextrapolation. For 300,000 years man couldn't predict anything. Then man learned to predict the motion of one planet and suddenly man thought that he now could predict everything. That was always just a psychological delusion. Why do you want to continue being delusional? What's the upside here?
    1
  7409.  @Thomas-gk42  Well, there is a kind of soft determinism that assumes that a godlike being can predict everything, even if man can't. Often that's a animist kind of belief system that assigns some form of personality to nature. "Nature knows what is going to happen next." is, of course, a completely nonsensical idea. What does it even mean that nature knows if she can't tell you because of relativity???? Technically hard determinism falls flat on its face even classically, see e.g. Maxwell's demon as an example for the consequences of such a perfect predictor. If you want to take it from there, then a perfect prediction machine can predict at your birth who will marry you, when you will die and, most importantly, it can resurrect you by turning the motion of your molecules around! Wait a minute... how can a machine that can resurrect you at the same time predict the time of your death? ;-) As with all things "perfect", one can produce trivial contradictions by consistently applying that attribute. It is, logically, pretty much like an argument for a perfect, all-knowing god.

  7410.  @Thomas-gk42  Determinism doesn't do anything to anybody. It's just a failed mental model.

  7442.  @briancornish2076  I am simply talking about pi as a source of a sequence of symbols here. OK, so let's call that a numerical representation of pi, instead. Does it contain a finite or an infinite amount of information? There are people who want to define information as the length of the shortest possible algorithm that can reproduce the original sequence. On some level that is a very good operational definition, but as you can see it reduces the representations of pi to something of fairly trivial information content, while many less famous irrational numbers would be the kings of information infinity. Actually, make that "almost all irrational numbers", because the number of finite programs is countable.

  7443.  @briancornish2076  Information isn't about meaning. Meaning is not something that can be quantified rationally.

  7445.  @briancornish2076  The simple fact is that sequences that have the most information content (by the definitions of both information theory and physics) have the least "meaning" in human terms because they are essentially random number. This is a very "unfortunate" property of "information" because it confuses the heck out of everybody (including physicists, I am afraid). I don't know what else to tell you (and the public in general). This stuff is counterintuitive and nobody has found a "good" measure that satisfies our emotional needs for "order". You can, by the way, find plenty of examples in the history of science where human need for "divine order" has turned out to be completely counterfactual. Examples of that are platonic bodies in the theory of matter, the harmony of the spheres in celestial mechanics and similar projections of "pleasing symmetries" onto natural phenomena. The reality is different. Nature has absolutely no problems with cacophony. She actually thrives on it.

  7450. He is pointing out that the problem occurred in classical physics and it has nothing to do with quantum field theory. In classical physics we can make repetitive measurements on the same classical body at spacetime points (t0, x0), (t1, x1) etc.. The theory then translates that into a dynamical path variable x(t), even though that is NOT what we are actually observing. In modern physics we have to let go of the x(t) path completely. It simply doesn't exist.

  7451. I don't know if it's normal. I was taught reading and writing in first grade and I made it all the way to physics PhD. Neither skill (nor math) ever set me back, so it's not necessary to teach children to read before they go to school. The problem in the US are middle and high school. Since we are sending slow learners and fast learners to the same classes we end up with overtaxing the slow learners and underchallenging the fast kids. Other countries are solving this with a multi-tiered school system. Kids are being separated into two or three different schools, typically after fourth grade. That was no kid has to experience the frustration of being completely outclassed by their peers and/or being bored to death by the glacial speed at which the material is being taught.

  7468. We have mathematical tools that analyze systems by scale (Fourier spectra, for instance, and correlation functions). Many complex physical systems do not generate one specific scale, though. They tend to develop a power law spectrum similar to colored noise. That has a lot of nasty mathematical consequences (it makes these systems really hard to predict, for one thing). When a certain scale develops (e.g. the size of animals), it's very often because the system runs into some kind of hard limit. A well known biological example is mammals that need to breathe and remove excess heat, both of which get harder as the size of the organism increases, until both get so hard that no further growth is possible. A well know physical example is the growth restriction on accretion disks of stars, black holes etc.. As these gravitating bodies swallow matter they create a very hot gas halo. The radiation pressure from that halo pushes new gas that is falling in back out, thereby limiting the growth rate of the object to the so called Eddington limit.

  7469.  @SMMore-bf4yi  Science is the rational description of nature. It has nothing to do with engineering applications of scientific principles like reforestation. The people involved are not the same, the goals are not the same and the modus operandi is not the same. In engineering (even in ecological engineering) there are only three laws: 1) Make it work. 2) Make it work on time. 3) Make it work on budget. Totally different mindset. If you want to plant a forest, you worry about cost/tree. If you explore the biology of a forest you worry about root density and beetles that bore into tree bark.

  7470. What vacuum seals? The whole thing is either a tunnel or a welded steel tube.
    1
  7471.  @AdrieKooijman  A flexible airtight vacuum connection is called a bellows. Check it out on the internet. It's a basically fool-proof technology. Having said that, I think a self-sealing piston-ring architecture is probably cheaper. The trick with pressure seals is to make the higher pressure side do the sealing. You never want to rely on the material itself to provide the necessary pressure on the gasket materials. In any case, the Elon Musk proposal puts the train into a tunnel, in which case there is no change in geometry, to begin with.

  7499. There is no overlap between physics and neural networks. Physics, that's things like general relativity, magnetic properties of materials, physics of plasmas.

  7508.  @tigrankhachaturian8983  All of computing is about generating side effects (a result). The functional approach in CS was invented as a mathematical proof technique. It has absolutely no use for actual computation and is physically impossible (every computer generates heat as a completely unavoidable side effect).

  7534. China managed to prevent the outbreak for three years. They just never managed to vaccinate their population. That is their only mistake.
    1
  7535.  @huntermoon6220  Of course the vaccine prevents transmission. A person who isn't getting sick does not transmit the virus. Dude, we teach this in kindergarten. What were you doing back then? Drilling for oil in your nose? And what's with the childish crayons, anyway? ;-)

  7536. Nobody of importance has ever taught that Hilbert spaces are physical. We are actually trying to get students to understand that they are not. You were clearly not paying enough attention in your undergrad classes. ;-)
    1
  7537. There are no electron "particles". That's just a really, really poor choice of language from the early 20th century. An electron is a small amount of energy, momentum, angular momentum and charge that transfers irreversibly from one system to another. Whenever somebody tries to explain quantum mechanics with "particles" you know that you are listening to a person with Dunning-Kruger. Unfortunately that includes a lot of undergrad textbook authors.

  7538. The universe itself is sending you a signal from 300,000 years after the first second of the big bang. That signal can be detected with little more than a slightly larger tv antenna, despite the fact that it came form across 45 billion light years or so. The universe doesn't set any limits on communication within at least the local group of galaxies. If somebody wants to talk to you, they can.

  7548.  @kaynbred3882  The debt simply goes away. It can be cancelled out by the government's monetary policy. That's not the problem. The Chinese debt per capita isn't all that high, to begin with. The big problem for the Chinese government is to transition a generation of construction and ironworkers to higher technology jobs, otherwise they will end up with millions of men of a lost generation. We shall see if they can do it or not. China is certainly a giant sociological experiment. It may or may not turn out well.

  7551.  @luiseduardohd  Wikipedia has an article about the "Ultimate fate of the universe". It has the right keywords. The problem is that predictions, especially about the future, are notoriously difficult. Take what you read and hear about this topic with a good dose of skepticism.
    1
  7552. You will have to take a few serious physics classes on the subject, I am afraid. That moving charges transport the energy is easily falsified by the sun. There are no moving charges between the sun and us, and, yet, the sun deposits enormous amounts of energy on Earth's surface.
    1
  7553.  @camilojcastillo  And by "serious physics classes" you mean "none". OK. Say, what's the drift velocity of electrons in copper? :-)
    1
  7554.  @camilojcastillo  If electrons were moving like a chain, then the propagation velocity of electricity would be limited by the equivalent of the speed of sound in the electron gas, which would be far from the speed of light. I don't have anything against you, either, but I would advise you to take some serious physics classes. :-)
    1
  7555.  @camilojcastillo  Yes, that's the speed of the electromagnetic wave around the conductor. The electrons are not doing any of that. That is what they would have taught you in a serious physics class. :-) And, no, you will never see a water wave moving fast. It can't even move nearly as fast as the speed of sound is in water. That's good news for people who like to be at the beach, by the way. You don't want to be hit by water at 1500m/s. That would ruin your day... and all following days, too. :-)
    1
  7556.  @camilojcastillo  Did you take a serious physics class, yet? :-)

  7557.  @camilojcastillo  Sounds like you are in good company. Now go and take a serious physics class. :-)

  7558. A lot of small and medium communities have those problems, especially for youth. Adults can deal with the "there is no there there" atmosphere, but to teens it's hell on Earth. They need mental stimulation, which does not exist. I grew up in a small town like that. The boredom was only made bearable because we had good high school teachers who organized weekly intellectual activities for us. Well, in hindsight... maybe they didn't just do it for us. I have a strong suspicion that they did it for themselves, as well.

  7563.  @MarshallMadrigal-j2h  That is an often repeated falsehood. You are welcome to read the bible. You will find that it does not contain any scientific content, but it is full with politics. The Abrahamic religions, in particular, came out of late iron age politics. That's the reason why they are so useless: the conditions that created them haven't existed in almost 2000 years.

  7564. The US doesn't need to test. We have scientists who can design a functional new nuke before lunch using the perfectly debugged design codes. Where we are lacking is investment in production facilities. I don't know if we can make new pits easily.

  7565.  @bobbyfred3761  This is all irrelevant because these are not legally enforceable contracts to begin with. Nuking your own soil is also hardly an escalation. At most it's an environmental disaster. If the Russians do it to spike us it is, at most, the stupidity of the attention troll.

China is flaming out because demographics is destiny and India can't even educate its own population. The same is true for South Africa... and Brazil is self-destructing politically at the moment. So we might as well call them the four economic stooges and the total idiot that went postal. ;-)

  7591. The interest in special Hamiltonian systems like this has never waned in the theoretical physics community. You can find all kinds of curious special cases (like the question if there could be n planets in the same orbit at different angles in a stable configuration) in the modern classical mechanics literature. From a practical perspective it is far more interesting, IMHO, that all numerical simulations of the solar system seem to indicate that it is unstable at the 10 million year scale (even after the inclusion of first or second order general relativistic corrections)... and yet here we still are after four billion years, which indicates that we are missing an important element in our simulations. My bet is on a stabilizing dark matter halo. If I am right, then dark matter is not just important at the cosmological scale. It is literally a life-saver in your everyday life.

This, of course, at the expense of most of the Russian ground forces, a couple of major Navy vessels (there is very little left of the Russian Navy to begin with), a good part of the Russian air force and basically every cruise missile and other precision ammunition that Russia has. Not to mention a complete isolation of Russia and the destruction of its entire economy. And for what? To satisfy the dying wish of a 70 year old psychopath to play war? That's all there is behind this, really. ;-)

Most of the relevant economic output of this country depends on educated workforce in jobs that make $100k or more, these days. Yes, we have a very large, very unproductive low wage economy below that, but it doesn't represent the future but a past that never was and that is going away rapidly. Leave the manufacturing of $100 refrigerators to Mexico. That's where it belongs.

You can look at 1500 years of Christian history and count the generations that were (and still are being) held back by religion induced intellectual laziness.

  7624.  @neillibertine3044  There simply are no particles in quantum mechanics. There is nothing to discuss about that. Quanta are amounts of energy. They are not "objects" but system properties. If you are personally offended by that, then you have to think some more about quantum mechanics on your own time. I can't do that for you. I can only tell you what QM is and is not and it is not a theory of particles. It is a theory of energy transfers.

  7625.  @neillibertine3044  What are the most general systems that we know about? Fields. If we want a fundamental theory, then we have to study fields. Unfortunately it turns out that fields are very hard to study, both experimentally and theoretically. That's why we don't start physics with fields but with systems with discrete "components" like "chunks of matter". For instance, the most important of all solvable classical particle systems, the Kepler problem, is handled by abstracting a gravitational field and the matter fields away. We decide that we don't care about the nature of matter and assign a classical kinetic energy to chunks of it and we decide that we don't care about the details of gravitation and we describe it in a simplified way as a potential energy term (that depends on the distance of the centers of mass of our chunks). We are then solving the equations that transform kinetic energy in potential energy and vice versa (while obeying global momentum and angular momentum conservation). The critical term that describes which particular system we are analyzing (Kepler problem, harmonic oscillator, pendulum etc.) is therefor the potential energy term. It is here that we can realize that potential energy does not belong to any particular constituent of the system but to the system as a whole. No matter how many parts (chunks of matter, springs etc.) the system has, there is always one potential energy term that describes all of it. You are correct that this is not how we are teaching classical mechanics in high school. We are, however, teaching exactly this in the first theory classes in university by introducing the Lagrange and Hamilton formalisms. Then, a semester later, or so, we are teaching students how to "quantize" these classical systems by using the Schroedinger formalism, which replaces the kinetic energy term with a Laplacian and the potential energy term with a multiplicative linear operator. If you happen to take classes on electrodynamics (the most simple of fundamental physical field theories), then you can later learn in your graduate level QED class how one goes from the Hamiltonian of the electromagnetic field to the quantized field equations by inserting it into a path integral. That, like the Schroedinger equation, is a quantization procedure. It is, however, a much, much more complicated one with sheer endless mathematical consequences that are still not fully understood, yet. In any case, the big picture is that we never work with "chunks of matter" in these theoretical descriptions. We are always working on the level of system energy.

  7626.  @neillibertine3044  "first thing first, if an atom is in higher energy state how it come to so." Usually by absorbing a photon, i.e. from the electromagnetic field. That is already a simplifying description because "an atom" is actually an electromagnetically bound system. The atom/em field distinction is already a system boundary made by physicists, it's not one made by nature. So when you say "extra energy from outside", then you are already using the system language that I was talking about. That atoms are "particles" are semi-classical approximations that you were taught to believe in in school because it is extremely difficult (and in most cases also unnecessary) to describe atoms with quantum field theory. The only difference between us is that I know when I am dealing with an approximation of that kind and you are glossing over it. "Field theory, field whether scalar like temperature or vector like electric, dont exist without particles." Why does an electromagnetic field not exist without particles? The classical field description is through either a four vector with a scalar electric field potential and a three vector for the magnetic vector potential. You can expand that to a four-by-four tensor for the electric and magnetic field components, if you like. Once you quantize that you won't get particles, either. What you will get are field quanta, which are energy/momentum/angular momentum (spin) values. There will never be "an object" jumping out of a quantized em field. Experimentally that is fully supported by something as trivial as solar panels. They absorb electromagnetic field energy at 1e15Hz and convert it into a different form of electromagnetic field energy at near 0Hz. No particles needed. "About kepler description, there is no conservation of angular momentum for elliptical orbit, so keplers description is faulty." You really need to go back to your physics books for that one. It's completely false.

  7627.  @neillibertine3044  There are no particles. :-) I would suggest you clean up your physics act first by learning that all central potentials are angular momentum conserving.

  7628. @UC35cKjwzdRtI-PHvy7ZFViA Everything emerges from quantum fields. Energy is the same property of quantum fields as always. I don't know why this seems strange to you. "Quantum field" only means that these fields behave in a certain (and extremely well tested) way. There is no magic to it, except that you didn't read enough books about these things, yet, and you have not done enough experiments with them, either, to feel emotionally secure about your knowledge about them. Philosophy is bullshit. I won't even go there.

How about work in advertising, real estate sales or motivational speaking?

  7649.  @RebeccaTurner-ny1xx  I know the history of the Palestinian people. They got a very rough deal some 75 years ago. This means the Palestinian people had three generations to rebuild their lives somewhere else. That's a lot of time. It's a lot of opportunity. Time and opportunity that could have been used to turn from revenge to a positive outlook on life in exile. If you get a rough deal in life you have two choices. You can either bask in your misery and plot your revenge or you can move on. Universally those who move on fare better. They live happier, healthier lives. Their children grow up without hate and with an open future. They are not being shackled by their parents' and grandparents' dreams of revenge. So, I am asking you, again: How do you think did this work out for the Palestinian people? Are they happy, healthy people? Did they achieve any of the goals of their grandfathers and great-grandfathers? Did they drive Israel into the sea? Did they return their lands to their children, grandchildren and great-grandchildren? Was it worth it? What do you think? Is this all objectively better than moving into exile would have been?

I did work for other branches of government R&D and they are a lot of things, but not inefficient. All of that changed when I heard Rumsfeld's admission that they couldn't "track" trillions of dollars in Pentagon funds. At that point it became obvious what size the US shadow funds are and we can assume that a significant part of NASA's budget is part of that money. There is a lot of cold war stuff going on behind the fences that is not officially acknowledge to and funded by Congress. As it should be. We do not want to tell our adversaries what programs we are running by disclosing them line item by line item.

I am a man, by the way, and please excuse my bluntness, but in case of an economic collapse I can't even sell my body for food. That is a last ditch economic strategy limited mostly to women. Hence I, personally, need an economic system that does not collapse. Capitalism hasn't collapsed in many centuries. Everything else about the matter is just gobbledygook.

  7658.  @chervilant  Capitalism is the control of the means of production by private shareholders. It doesn't say that those shareholders have to be men. You may have a bone to pick with the patriarchy, and I support that cause, but that has nothing to do with capitalism. I also don't believe that socialist Cuba was ever run by a woman called Fidelia Castro, was it? If it was, then she would have been a sensational bearded lady sideshow artist. And please trust me on this... nobody would want to buy my body. Old male goat is not popular with the gay people, either. So, yes, I still need capitalism to continue to fill the stores. So do you, by the way.

  7680.  @georgelionon9050  If your nest is dirty then you might be right, but nothing about physics is dirty the way Sabine makes it appear. Her argument about high energy physics being at an impasse was discussed among high energy physicists when she was still in Kindergarten. She didn't discover the energy desert problem and she has done nothing to solve it. That string theory is "not even wrong" was also known long before Sabine was ever a name in the public's eye. It has nothing to do with theory. It's a trivial consequence of the weakness of gravity. It simply doesn't give us anything to describe beyond the level of general relativity. There is no reproducibility crisis in physics, either. We have literally spent billions of tax payer dollars to validate major results. Her understanding of quantum mechanics is trivially wrong. She hasn't even read the literature up to 1932 for all I can tell and the publications with her name on it are not worth the paper they have been printed on. Whenever she talks about nuclear energy and renewables or the climate she gets major facts wrong, which shows that she hasn't even spent ten minutes on research.

  7681.  @jarlsparkley  I am an experimental high energy physicist. I was there when they designed LHC and its detectors. I talked to the theorists about these problems. I sat in dozens of science talks where these problems were discussed seriously by people who actually understand them. I have read approx. 2000 pages of detector design proposal documents front to back (plus some of the design documents of the SSL, which was the way better machine) and as a result I got to design one of the central elements of one of the world's largest high energy physics detectors. Unlike Sabine I have actually accomplished something of lasting value in physics. ;-)

  7683.  @jarlsparkley  All you are spelling out here is that you don't know anything about physics. :-) The existence of an energy desert, for instance, is not a problem. It's a highly likely fact. An adult simply accepts facts instead of complaining about them. That string theory is not even wrong is also just an EXPERIMENTAL fact. Theory doesn't change nature. Theorists can't make gravity stronger just because it would be more convenient for experimentalists. Let's say somebody discovers the correct theory of quantum gravity tomorrow by chance. It would be EXACTLY as untestable as string theory. That you don't understand this makes you the very kind of fool that Sabine is making money with. ;-)

None of you are making any sense here.

  7688.  @MattiasDavidsson  Listen to me, again: there are no particles. There are only quanta of energy. That is what we are measuring. A quantum of energy is like the outcome of a dice toss. It's like one of the numbers one to six. The universe doesn't know anything about that outcome before it happens. It's just as ignorant about it as we are. THAT is what quantum mechanics deals with. This total ignorance of both the universe and the physicist. Nothing more, nothing less.

Time is simply not some abstract philosophical quantity that nature somehow provides to us. It's in no way shape or form different from a yardstick. We can make yardsticks out of metal, wood, plastic or even light. In the same way we can make clocks in many different ways. All good yardsticks agree with each other and so do all good clocks. That is all there is to it... and you would know all of this if you had been paying attention in school. :-)

  7766. The universe is not deterministic. We even teach non-deterministic processes at the high school level. Think classical friction. If they ever made you do a friction experiment, then you have experienced a macroscopic non-deterministic process yourself: sticky friction can not be predicted. The force at which the body starts moving against sticky friction is random within a certain range. There are many other such phenomena in nature. The delusion that nature is deterministic is simply based on an extreme case of scientific tunnel vision during the 19th century when orbital mechanics was the best physical theory we had. Physicists have overcome this state of delusion about a hundred years ago (119, if you count special relativity, which gives you the microscopic explanation why nature CAN NOT be deterministic). The philosophy department is still totally into this nonsense, it seems. Please try to catch up. If you don't know why Copenhagen is 100% correct, then you simply didn't study it enough and if you don't know why MWI is total nonsense, then you didn't read Everett's thesis. The major mistake is in the second sentence. Philosophers are clearly not reading the literature. :-)

  7769.  @professornebula6545  Where did I mention randomness with regards to microscopic processes? I didn't. One can actually prove pretty easily that the microscopic world can not be random. Random process inevitably create dissipation and we don't observe dissipation. There is even a fitting name for this proof: fluctuation-dissipation theorem. Energy, momentum and a few other quantities are perfectly conserved locally as far as we know. This is so both at the macro- and at the microscopic level. What is locally not "conserved", so to speak, is our knowledge about the world. How comes? It's caused by phenomena like non-integrability for classical Newtonian systems (which make the claim that everything can be calculated nonsensical, even at the most primitive level of physics) and even more so by relativity once we look at the world the way it really is. In a relativistic universe all systems are necessarily open. Energy, momentum and angular momentum are constantly "escaping" towards infinity. That leakage is what makes the local state unpredictable. We can't do the local accounting unless we "collect" all the missing energy etc. with some "hermetic" detector array that surrounds our local coordinates. To get the information about the measured results back we also have to wait for the finite time that a measured signal takes to propagate back to us from our distant collecting array. So that means that the current state can only be fully known in the future and even then only if we are extremely diligent (which is not even possible). In practice this means that the present is entangled with the future. It's not just any near term future. It's the entire future of the universe. THAT is what causes the world to be non-deterministic. It doesn't mean that it's random, but it means that it's not knowable, neither to us nor to nature. If you want a poetic description, try this: How do you know what you look like? You need to look into a mirror. Well, surprise! So does nature and because she doesn't have a mirror, she can't tell you what she looks like, either. Makes sense? You are correct about one thing. Whether I have a PhD or not makes no difference to my arguments. It does make a difference to me, because it means that I have been thinking about this very thoroughly for a very long time. Much, much more thoroughly than most people. That causes a level of mental clarity that is otherwise hard to achieve. You can get there, as well, you just have to spend the fifty years on this stuff that I put in, already, and unlike you I am exercising every day on the internet by trying to explain physics to people, whether they want to hear it, or not. Every time I am repeating my argument I am learning, whether any of you are listening, or not. I am much, much more knowledgeable about the basics of physics than I was 20+ years ago when I began talking about physics on the internet. I used to tell people a lot of bs about quantum mechanics back then, but then I noticed that I was talking bs and I began learning. Today I know better. I am self-correcting. Can you do that, yet?

    1
  7793.  @jonaswox  Yes, that is bullshit. If you roll dice and the outcome is "1", that's not statistics and it's certainly not probability. It's a cold, hard fact. If you roll dice ten times and the outcomes are two "1s" etc., then you have a statistical measure for that statistical sample outcome. To get from there to probability you have to take a giant leap of abstraction and assume that you can repeat the same experiment an infinite number of times AND that all repetitions are completely independent of each other. At that point you have left the realistic level because no experiment can be repeated independently an infinite number of times. And now you have a serious problem, because if you actually try to fit probability theory to physics naively then you will notice that it does not (and can not) obey any of the conservation laws and with that it's dead in the water as a microscopic theory. The correct microscopic theory still retains the same assumptions about experimental repeatability and independence but it is NOT probability theory but something completely different called "quantum mechanics", or, to put it more precisely, it's the unitary representation theory of the Poincare group.

It's a really tough decision in terms of user interface. The solutions that look cool are not safe and the safe solutions don't look cool. The only thing that Tesla messed up big time IMHO is the speed indicator. That should have been right in the center of the driver's visual range. That's the only information the driver needs constantly, unless we let "autopilot" chose the speed for us.

  7805.  @MaticTheProto  I agree. Tesla's design decisions are sometimes a bit questionable. The display in the center for sure is... but then... most cars had those controls there forever (even log before displays even existed), so it's not like Tesla invented the bad solution. Tesla only refined it with moving the speed indicator out.

He didn't discover the physics of planetary motion either (that was done by people like Copernicus and Kepler), he merely gave us a rational explanatory framework for it.

  7836. No, there are no such experiments. Superposition is not a property of quanta. It's a property of the theory. That property is there BY DESIGN. Whenever you measure a quantum you get exactly one outcome. Same for quantum computers. The final state of one run has exactly one physical value. Depending on the algorithm multiple consecutive runs of the quantum computer can result in different outcomes or they can result in the same outcome.
    1
  7837. @ Seriously. Quantum mechanics is not a big deal. It's the natural explanations for the behavior of systems that make "click-click-----click" like a Geiger-Mueller counter. On a slightly more theoretical level you can derive it from the sentence "Quantum mechanics is the unitary representation theory of the Poincare group.". The only thing between you and quantum mechanics, at this moment, is the amount of learning to parse that 11 word sentence. Admittedly, that requires years of effort. There are no more shortcuts here than between not playing the piano and playing the piano. ;-)
    1
  7838. Exactly. But mathematics has historically followed physics very closely. Set theory is the behavior of collections of classical objects and their properties. Euclidean geometry is the generalization of the physics of the tangent space etc.. Complex numbers are rotations (and scaling) in two dimensions. So, yes, mathematics borrows very heavily from physics. That's why it's useful for physicists to begin with.

  7853. C is basically just a smidgen of syntactic sugar on top of what your CPU instruction set does (that's why it does not hide endianness, for instance, because that would be an awfully inefficient thing to do on CPUs that have the "wrong" bye order). It requires you to think at least a little bit about the hardware that your program runs on. Not too much, just enough to make you a really good programmer over time. If you are trying to avoid that level of knowledge, then you will always stay a mediocre programmer because performance is, whether we like this or not, hardware dependent. Not saying you can't get around low level stuff most of the time by using optimized libraries and LLVM, but nobody ever died from looking underneath the hood of their car.

  7872.  @cyagen9782  I haven't been following German politics for a few decades, so I can't comment on individuals. Competent politicians are generally rare. The best ones are usually trying not to get in the way of competent administrators. Maybe you are not old enough, but I can assure you that the Bundeswehr was already underfunded under Kohl. It's not a recent development. NATO, including the US, always saw the German army as canon fodder in the conflict with Russia. Having a half million strong army with limited resources opposing the Russians during the cold war had only one purpose: to buy the Americans and the Russians enough time to determine if WW III was going nuclear or not. That was well understood within the Bundeswehr 30 and probably even 50 years ago. There is absolutely nothing new about the situation and it is not specific to any political party. Germany is not an equal partner within the EU, not even on the level of economics. It is still the 19th century juggernaut of Europe and given its size, geographic location, population size and industrial strength it will continue to stay that. The other European countries have absolutely no desire to see it armed in addition, Russia or not.

  7881. The uncertainty principle is a fairly trivial mathematical lemma about certain types of linear operators. There is nothing really difficult or exciting about it. The mathematical proof takes a quarter page or something, at least for L2 functions. One can prove it with some more effort for more general cases. That's a common property of functional analysis lemmata. Many of them are quite trivial (at least for a mathematician) for well behaved functions and have technically difficult to prove analogs for less well behaved functions. Physicists are almost always working in L2 for these kinds of problems, so the visualization for what is happening is lengthier than the actual proof that it can't be any other way. Mathematicians, on the other hand, are almost universally interested in "strange functions" for which these relationships are much, much harder to establish. The "glorification" of Heisenberg's uncertainty relation in particular is therefor more of an educational side effect that stems from a lack of modern calculus teaching in high school. We could include the more trivial aspects of functional analysis (like this result) at the high school level, if we wanted to. Unfortunately our high school curriculum is stuck in the late 19th century and does not want to come into the light of the 21st.

I am not a mathematician and I haven't done this stuff in forty years. What I am saying is that I know that the average high schooler can be taught how this stuff works with the proper teaching method. Our schools are, unfortunately, not well prepared to teach students modern material. The way we teach calculus is roughly from around the 1860s (epsilontics, Weierstrass) or earlier (inifnitesimals, 1670, Mercator, Leibniz) and it is very pedestrian. These things here are from the 1920s. We are another 100 years later, so why are we still teaching like it's the baroque period? Shall we also hand out wigs and powder to the students? :-)

If we take numerical problems out, this indicates that we aren't simulation reality but only an oversimplified version of it.

  7920. The two types of physical interactions are called "reversible" and "irreversible". Measurement outcomes are, by definition, the results of irreversible processes. They can not be undone. Before such an irreversible process takes place there simply is no outcome. The idea that a quantum mechanical system has a state before it is being measured is simply 100% false. The same is true for "random" systems like dice in a classical setting, by the way. We are not teaching any of this very well in school, and most people simply don't spend enough thought on it to figure it out on their own.

  7923. What nobody seems to notice is that DRAM was only a minor part of a computer. The Japanese never made an even halfway decent CPU and they never captured any significant market share outside of the memory business, either. The hard drive business is basically a legacy business. Hard drives are in a desperate death run with Flash that they will inevitably lose. The cost comparison is false, anyway. The unit cost of a hard drive bit is only significantly lower than that of a Flash bit if the drive is being used to store cold data. Drives have basically become the new tape. Backing up an 18TB hard drive now takes on the order of four days, which will soon make them useless for personal use. Only a data center can run infrastructure that has 30 day cycle times or more.

Neither is there something like wave-particle duality. That's just an old false dichotomy fallacy. Dirac pointed this out around 1930 when he remarked that "quanta" are not either-or but they are a completely independent third phenomenon that simply doesn't exist in classical mechanics. You will never understand nature if you keep thinking in these failed categories of the past.

  7959. You do understand that refactoring is the antithesis to "never break a working system" super-rule, right? ;-) Here is the thing... you aren't actually testing your code. You are testing your code's response to stimuli. Why do you need to refactor it for that? Unit-testing is usually done for unit-testing's sake. It keeps somebody's OCD happy at the cost of hundreds of thousands or millions of dollars. In reality that's almost never the level at which serious code problems occur. Let me give you a popular example of what happens in real life: Linux clones of Word are basically useless. Why? Not because of the billion bugs that they come with. You could fix every single one of those bugs and they would still remain broken because of the fonts. As soon as you import a non-trivial Word document into one of these tools you have to start the formatting all over, again. Nothing at the unit level and nothing at the application level can fix that. That "bug" was put in there by Microsoft's legal department by copyrighting Windows fonts.

  7965. Your first sentence is wrong, already. There are no "particles" in quantum theory, at all. There are quanta (which are energy values) and system states. There are ensembles and single copies of a system. None of that has anything to do with particles. Those only enter when somebody who doesn't understand quantum mechanics teaches it the wrong way.
    1
  7966.  @neillibertine3044  Matter is an emergent phenomenon of quantum fields. Protons and neutrons are bound states of quarks and gluons. Nuclei are bound states of protons and neutrons, atoms are bound states of nuclei and electrons, molecules are bound states of atoms and so on. Where quanta come in is during system changes. Nature doesn't know about systems. Nature is all one entity. Systems are definitions by physicists. We know that these artificial entities interact by exchanging globally preserved physical properties like energy, momentum, angular momentum, electric charge etc.. "A quantum" is an irreversible exchange of one or several of these properties. For thermodynamic reasons energy always has to change (that follows from the third law that does not allow zero temperature, which basically leads to a minimal thermal background energy density condition). So if any detectable change in a physical system should occur, there has to be an irreversible energy exchange. That is what we call "preparation" (aka "source") and "observation" (aka "detector"). As you can see, quantum mechanics is therefor a systems theory. It describes how physical systems interact with each other using measurable (classical) physical quantities. No particles required at any time. Classical mechanics is also a system theory, by the way, you were just never taught to understand it that way. If you had been taught properly, then the "emotional" transition to quantum mechanics would have been trivial.

  7969. The assumption that one can develop a rational range of tests that will overlap with the actual failure modes of the system is irrational, at best. It is highly religious, though, so I congratulate you on the strength of your faith.
    1
  7970.  @ModernSoftwareEngineeringYT  Your experience is not evidence but merely a witness statement. That is also something that is typical for religious beliefs. This is not to say that one shouldn't test software, but even a cursory look at theory tells us that claims about systems testing are questionable. The halt problem, for instance, is unsolvable for even trivial functions. Therefore the assumption that one can even build a complete test suit for a complex program is, at most, a nice fantasy. Yes, I know it makes us feel good to have such fantasies. We often even get paid for them. Good for you if you get paid for what makes you feel good. Beyond that, however, I would always chose a flexible engineering team with level headed people over a team that has a recipe for success.
    1
  7971.  @ModernSoftwareEngineeringYT  Sorry, but I don't trust any survey that I didn't falsify myself. :-) If you mean to tell me that you are making "success" dependent on methodology rather than organizational size and project funding (which, of course, correlates to the quality of the developers that will sign on to your organization in the first place), then you are predestined to play the new "Moneyball" in software development. Just ask Billy Bean how that worked out for his quest to win the World Series. :-)
    1
  7972.  @ModernSoftwareEngineeringYT  All I am saying is that methodology doesn't scale. The more complex it is, the less it scales down. Just because something works for Google and Microsoft (and we could argue that absolutely nothing works at Microsoft, in terms of quality), doesn't mean that it works in general. Yes, if you can afford independent teams for design and test and validation, then you should be able to produce better software. How many software development companies can afford that? And those who can, do they really produce better software because of the methodology or because they have more developers and not everybody is stressed out to the breaking point? I would suggest it's the latter. In comparison, how much software is being developed by single people? A lot. Worse, still, I used to do embedded systems, where I did everything except for the mechanical engineering. I did the circuit, the PCB, the debugging and I wrote all of the code that ran on the microcontroller. That product has 100% uptime. There was never a single line of documentation written by an architect. There was never a product definition and there is no test code. I simply wrote a functional software product around my own hardware. I don't think that I even documented the register maps other than in the source code. It still works without any methodology, whatsoever. Why? Not because I am a good software developer, either. I simply took the time to test every bit of the functionality manually. I knew my product in and out before it was ever shipped. That is my experience. It's my religion. I would not suggest that you try it that way at Boeing or a major game development team.
    1
  7973.  @ModernSoftwareEngineeringYT  Yes, science is a methodology, but it is unique because nature is unique. I would not compare science to engineering disciplines. Engineering is the art of making something functional for a reasonable, preferably low cost. It is always a matter of compromise. That also means that perfection is actually the enemy or engineers. And since we are into economics now, software as a business is basically dead. Google doesn't sell software. Google sells advertising. Facebook doesn't make software. Facebook mines user data. Apple doesn't sell software. It sells a brand experience. Gaming companies are strictly speaking also not selling software. They are in the business of creating dopamine. Software is, in all of these instances, just a means to an end, and it's the end that pays the salaries. I wonder how many software developers are aware of that?
    1
  7974.  @ModernSoftwareEngineeringYT  Yes, that's a general statement about engineering. It does not refer to software engineering in particular. When I make a test and measurement device, it's not an electronic sculpture. It's about helping someone to measure a particular physical quantity with a reasonable precision at a reasonable price. It's that "service" that I am getting paid for. It just happens that software is far less specific with regards to the service that it performs than hardware is. That is both its great advantage and disadvantage, from a competitive point of view.
    1
  7975.  @BosonCollider  That's kind of my point. In engineering "good enough" is good enough, but that comes more with experience than with formal methods. The best and most reliable systems I have built in my life are violating a number of formal rules, but that allowed us to simplify the system greatly, which made it really easy to implement. Maybe my most general rule for software development is orthogonality of functions and independence of execution order. That way test complexity is closer to O(n) than O(n^2) or worse O(exp(n)).
    1
  7976. What do you need either for? Inheritance is a bad idea on the best of days and polymorphism is mostly useful as a mathematical tool (it's similar to the ideas of category theory, where you reuse the same proof for multiple, often an infinite number of cases). In practical programming it only leads to very subtle errors that are hard to catch (try using Python for production code... you will see just how many runtime errors you get just by forgetting a dot in a constant, which then turns from a float that you wanted to an integer that is meaningless in the context). And, yes, things like 7*"Hello!" are great... until you run into a really large integer while doing n*"Hello!" and then your language suddenly allocates a petaByte of disk space for a nonsensical string. ;-)

  7981. Unitarity, i.e. the property that all emitted quanta are also detected, is an assumption of the theory. In reality all of this is marred by what experimentalists call "quantum efficiency". We can, at most, detect 80-90 of photons with our quantum detectors and we generally do not even count how many quanta our sources are emitting. 10% or more are always lost, even in the best of experiments, and then there is thermal noise in addition, which causes "false positives". All of that has to be dealt with at the experimental level when we are performing the systematic error calculations. The theory is not describing any of that.

  7997. Quantum mechanics is neither random nor probabilistic. Random numbers don't satisfy any conservation laws.
    1
  7998.  @DeJay7  Quantum mechanics is not probabilistic. It's uncertain, but even that is not the correct starting point. If you really want to understand the theory, then you have to realize that it is an ensemble theory where every single quantum experiment is independent, i.e. it is not possible to predict the outcome of any one measurement by knowing all the measurements. That is NOT the same thing as random, most people just don't think about it deeply enough. We know that the universe satisfies conservation laws event by event because we are observing them event by event. Hermiticity checks are part of every high energy physics experiment.

  8001. That is not as hard as you think. I was a conscript in the army of a NATO country when I was 18. I fully understood why it was a necessary disruption to my life. I also met and talked to cadets that were going to become officers. They explained to me that their families had a long history of service and that they were proud to become members of their country's military. There are enough people who believe in the mission of defense forces, just as there are enough police, first helpers, fire crews etc.. Pay these people a decent salary and give them the respect they deserve by putting their lives on the line and you are fine as far as staffing is concerned.

  8005. Because of relativity. If the two measurement events have a space-like separation, then there is no causal connection. We can always find two observers (traveling at different relative velocities) who will claim a different event order. One will say A came before B, the other will say B came before A. Since the outcomes are independent of those claims they can't depend on the order. In other words, we have to decide if we want to keep quantum mechanics local or give up on special relativity. If we keep special relativity, then quantum mechanics can not be non-local. There is a workaround against this argument, but that's super-determinism, i.e. nature can do whatever it wants but it always hides the violations from physicists. That's the "lying universe" interpretation. I find that both useless and questionable. The only other possibility would be to find an experimental violation of special relativity. So far that has not been seen.

There are very few corporations these days that are not trying to be kitchen clean in the way they do business. The consequences are just too severe. Not only that, but it's much easier and much cheaper to abide by the law than to circumvent it. So, no, the idea that corporations are successful because they know how to skirt the law is completely wrong. Corporations love regulations. Why? Because they make the barrier of entry for new startups very high. It is much easier to work with the law within an established operation than it is to achieve compliance with the law from scratch in a newly set up entity. That is a competitive advantage, not a disadvantage. Only amateurs think otherwise.

  8034. When I throw dice and the outcome of a throw is four, does that make the probability of the outcome four 100%? You are mistaking a property of an ensemble of systems (i.e. infinitely many copies of the same system) with the measurement of a state of a single system. After you have done your measurement in quantum mechanics, the system is destroyed. It's not simply repeating itself with a new initial value. A typical quantum system is a decaying nucleus. When you make a measurement, then you will find one of two states: 1) The original nucleus is still there or 2) The nucleus has decayed and instead there is a new nucleus in its place. The other decay product, e.g. a released gamma, has deposited the decay energy in your detector. You never get back from state 2) to the initial state. There is no "ensemble" to be had from the same experiment. You have to start over with a "brand new", not yet decayed nucleus. This is the gist of all quantum mechanical experiments: they are, by definition, unique and irreversible. We can make many copies of the same setup if we like and do the measurement over and over, again. That will, eventually, give us an estimator for the square of the absolute value of "the wave function". We will never get the wave function itself. The measurements can only give us the absolute value at any give time and place but never the phase.

  8045. Measuring one quantum doesn't change the outcome of the measurement of the second. The measurement adds an uncertainty to the spin state that depends on the relative angle between the source and the measurement device but it does NOT set the spin state. That's a common misunderstanding.
    1
  8046.  @Epiphone1964  Choosing the axis of measurement (polarizer or Stern-Gerlach) simply changes the uncertainty about the local spin state. If the axis is parallel to the spin state, then we get zero additional uncertainty. If it's orthogonal, then we get maximum additional uncertainty. The measurement is simply not angular momentum conserving if it's not parallel to the spin state. The additional angular momentum comes from the measurement system.

It doesn't matter how we package these functions and how we call them. The goal of programming is always about an algorithm to solve a problem (and solving that problem is the actual goal, but never mind that). What makes this a quality class is that he is teaching you what the compiler does with your code, because that is important, no matter which paradigm you use and in what language you write. This looks like a much better class than some others I have seen (even from Stanford professors).

  8079. The problem is that there are no "possible futures". Nature doesn't offer them on a menu that we can pick from. The future is, however, not determined, i.e. it is not cast in stone since the beginning of the universe. The philosophical approach with free will/determinism simply doesn't describe the actual facts well, starting with the fact that there are regions of spacetime that are simply beyond our control and other regions that can't control us. The past-present-future slicing of the universe is a false mental model that is a leftover from Newtonian physics. What you are experiencing should be called something other than "free will". Let's call it "agency". You can subjectively and objectively change your environment, to the better or the worse. That is part of the human experience and it is not contradicted by anything in modern science.

  8105.  @LuckyRich15  Entanglement has nothing to do with superposition. One can construct trivial classical entanglement examples that show the exact same behavior. All these arguments are the wrong way around, anyway. What rules the universe is relativity. It literally enforces the tensor product structure of quantum mechanics. It is NOT the other way around. Relativity DOES NOT depend on quantum mechanics, but QM depends on relativity. It is, IMHO, even completely caused by it.
    1
  8106.  @LuckyRich15  One can derive quantum mechanics from Kolmogorov's axioms for ensembles of independent systems and a dash of relativity. We can actually do more than that. We can derive all possible symmetries of quantum fields from Poincare invariance. So in a way a trivial set of barely more than half a dozen axioms that can all be shown to be correct empirically (within our best experimental technology) can be used to derive all of physics from first principles. The only "problem" left, so to speak, is that this derivation is not unique. There are many more possible quantum field theories than the observed U(1)xSU(2)xSU(3) symmetry of the standard model allows for. We don't know what else limits nature to this particular low energy solution among all possible ones, but that this is one of the allowed solutions is fairly easy to prove mathematically if we start with the most basic observations (that space-time is metric, empty and highly symmetric). It would probably not take more than a fairly thin textbook to summarize all the necessary math.

    1
  8109.  @sat25940  Dude, in the second sentence of his thesis Everett assigns the wave function to the state of the individual physical system. That is complete bullshit. The wave function is, by definition and design, a description of the quantum mechanical ensemble. A single system does not and can not have a wave function. In other words: a quantity that describes an infinite repetition of the same experiment is falsely assigned the role of describing the behavior of an individual system. THAT is what multiplies the number of worlds in MWI by an infinity. It's a trivial counting mistake. Wheeler did one worse, by the way. He assigned a wave function to the universe, which is not even a system (and it sure as heck can not become a repeatable experiment). These are trivial undergrad mistakes.
    1
  8110.  @sat25940  That wave functions describe ensemble averages follows immediately from the unitarity requirement. Where else would it come from? From god's toe fungus? Please, at least try to THINK about this rationally for a little while. And of course it is "canonical". The probability that drops out of the Born rule is an ensemble property. Single events don't have probabilities. If you don't believe me, try this: I measure a single quantum of 1.63eV at the position x=-14.3mm and y=28.5mm. What was its wave function? :-)

  8111.  @sat25940  YOU need to tell me what the wave function was because this is science. It's not religion. I don't take things on faith. If YOU can't tell me the wave function based on a single event, then the single event does not have a wave function. The only information we are getting from YOU not telling me the wave function is that YOU don't understand basic physics. Not that that's new information, anyway. That was obvious right from the beginning. :-) How do you know that the atom is in the ground state without observing it for a long time, by the way? Is god's toe fungus telling you that there won't be any energy coming out, even if you don't look? Dude, you are making a total fool of yourself here. Stop it.

  8125.  @msf559  Dude, physics is not fanboyism. You can't just pick your favorite physicist and believe everything they say. The entire wormhole thing is horrendous nonsense. ;-) Not being able to predict the next number in a sequence and randomness are NOT the same thing. The first property is called "(statistical) independence". Quantum mechanics and probability theory are both based on the assumption that series of events/measurements/picks from a set of possibilities are independent, i.e. that we can not predict the next outcome based on any of the previous ones. That doesn't make these outcomes random. Truly random events in physics would not satisfy conservation laws and can therefor be ruled out. Locally independent events are entangled with events in spacelike separated regions of spacetime. It is relativity that supplies this "pool" of independence. Nature doesn't have to compute anything. It gets it for free.

  8133. Yes. Just like China has subsidies for solar panels. The EU imports solar panels worth over $25 billion a year. It exports pork to China worth $1.8 billion.

  8136. @ for(i=0;i<1000;i++); does not require a mathematical proof of 170 pages. Absolutely everybody knows what we are doing there. Neither do mathematicians need a tome of an axiomatic arithmetic book like Bourbaki to solve the sum of the first n integers. The people who are doing that kind of foundational stuff are simply suffering from mathematician's OCD. They haven't changed anything about the field other than to add some crazy stories to it. Goedel in particular is completely irrelevant outside of mathematics. The only case it relates to are statements over infinite sets. There are no infinite sets in this universe. Never were, never will be. The halting problem is irrelevant for the very same reason. Most people who program computers DO NOT want the machine to halt. We are spending enormous effort on making software that never terminates because when your tv shuts down in the middle of a movie that's bad for your company's tv sales. What is relevant in reality is simply not what you are discussing here. Polynomial vs. non-polynomial complexity, now that is relevant even on small-ish problems but not assuming the excluded middle rule does nothing to solve those kinds of questions.

  8152. Heavy gravitons have been discussed a lot, both in the past and currently, but they have a problem: a massive boson mediates a short range Yukawa-like force, i.e. one that weakens with distance. That would work, on some level, to model dark energy. It does not work to model dark matter for e.g. galactic rotation curves. I believe it might already be ruled out by the arrival times of gravitational waves and electromagnetic signals (gamma rays, I believe) from neutron star mergers. I might be wrong.

  8153. And there is the crazy person...

  8154. That is exactly the wrong explanation. A quantum is neither a particle nor a wave. It's just a small amount of energy. We teach this in high school, by the way. Absolutely nobody listens. ;-)
    1
  8155. Bohm's version says nothing about the internal properties of "the particle". The math doesn't even suggest that there should be particles. Schroedinger's equation is very deceptive because it reduces a theory that can be formulated in any basis to a special case that is not even particularly useful. Most of the time we aren't measuring locations in QM but frequencies, which is far more precise.

  8171. Schroedinger was simply confused, as were most of the other founders. You can find early papers by Heisenberg in which he gets things completely right but later he "self-corrects" and falls back on wrong semi-classical explanations. Erring is human. Erring about non-intuitive effects (whether they are trivial if understood correctly or not) doubly so.

That's why Walmart, Amazon, Microsoft, Apple and Google have taken the leads in the list of most important and largest companies.

  8189.  @mildredmartinez8843  The worker doesn't create any riches. The worker works for his wages without taking on any risk. If workers want to profit the way investors do, then they have to start accepting the risks that come with any investment and work for free until the investment is profitable or (more often than not) the entire investment is lost.
    1
  8190.  @mildredmartinez8843  Words are cheap, kid. Buying risk is expensive. If you divide Amazon's current market cap by the number of its employees, then each employee would have to pay almost $15,000 to buy an equal share of the company. That's outright cheap, by the way. For Apple it's more like $15 million per employee. :-)

  8191. What I always found hard to "grok" about general relativity are the gauge degrees of freedom in the equations. I kept asking my professors about it but I never got a satisfying answer at the physical level. I can see the mechanics of the equations and how one has to use constraints on both the initial data and the actual evolution, but I could never develop a mental model to translate that into physical intuition. I don't know how the relativists are doing it. OK, I don't know how to play Chopin, either... it kind of falls into the same category for me. :-)

All suggestions of "warp drives" assume that we have copious amounts of matter with negative mass or negative energy at our disposal. Since the latter doesn't exist, these suggestions are basically just very complicated mathematical proofs that FTL travel is impossible, even in the GR scenario.

  8212. Object orientation is simply documentation. Once your compiler has transformed your code into machine code, all objects are gone. It is amazing how few OO programmers seem to realize this. All OO does for you, is to add a certain "standardized" documentation format to your code, which may or may not work well for your particular problem (it rarely works for mine). The compiler doesn't give a frell about your object structure, neither does your CPU.

Introspection just happens to be much more flexible. The only downside is that it requires case statements inside methods, which comes with a (tiny) performance penalty. That is rarely a problem these days.

  8257.  @dinobotpwnz  No, it's not. The real physics is that every measurement removes a quantum of energy from the system. That is what really causes the system to "collapse" (which was always a completely superfluous and nonsensical term). You are changing it irreversibly. If you don't know that, then you have never done a quantum experiment in your life. I suspect that you haven't, and that's why you can't correlate the formalism with the real world phenomenology.

  8260. Dude, if you don't want to work for less than twenty bucks an hour, then learn something that is worth more than twenty bucks an hour. What a concept! Now, I can tell you that in the medical industry plenty of professionals are raking in $500 to $1500 per hour, but those folks are typically lawyers, doctors or PhDs with decades of experience. Do you know what that means? It means that they didn't just pay attention in high school while you were smoking weed but they put in 24/7 for four to eight years in university and then worked their way up in the hierarchies of their law firms, medical departments and research facilities year after year after year, rain or shine. You don't just get these jobs for being a slouch. You get them because you worked for them. Some people do, that is. There are ten times as many people who are just as smart and who put in just as much work and who don't manage to move up the food chain, for whatever reason (bad timing, poor job choices, personality, bad bosses etc.). Those are the real losers. You are just an average complainer who didn't even get into the game.

  8264. It doesn't come from anywhere. It's not "free" energy that we can harness to begin with. We are locally gravitationally bound and therefor there is no expansion around the local group of galaxies or inside the solar system itself. Everything that has a certain distance (that is set by gravitation) remains at that distance (up to Newtonian or GR motion). The problem with the expanding space picture is that we are used to think that space is an absolute background without matter. As it turns out, it is not. What keeps spacetime "together" is the matter. Where matter dominates, spacetime falls into the gravitational wells. Where dark energy dominates, spacetime keeps expanding towards infinity. This is hard to visualize because we can not think in four-dimensional spaces that have a local Lorentz metric. At least I can't. Maybe people who have a better grasp on general relativity can.

  8265. Europeans have an even poorer understanding of macroeconomics than Americans. There is no such thing as government debt. All government spending is an investment in the future. The more the better.

  8266.  @rosshilton  Depends who you are borrowing from. If you are borrowing from private investors, then there is. If you are printing your own money, then there isn't. That's the reason why government should NOT borrow from its citizens through bonds. It does NOT increase the money supply, which is what you actually want. Dude, it is not me who needs a lesson in macroeconomics. You simply don't understand the difference between distributing shit differently and making new shit. ;-)

  8267.  @rosshilton  It is not devaluation if you are doing it proportionally to the stimulus that it creates. There is no money that is not in circulation. Banks are not hording trillions of dollars. That's just a gold nut fantasy.

  8268.  @rosshilton  Only if everything else is equal, which it is not. The government doesn't just throw money on the streets. Let's say the government orders F-35 jets. That's billions of dollars to the aerospace industry which buys raw materials from the chemical industry, heavy industries and parts from the electronics industry etc.. Every new dollar circulates repeatedly through almost the entire economy and most of it eventually ends up in government tax receipts, which allows the government to spend even more. Again, kid, you aren't paying any attention in school. ;-)

  8269. Actually, the Soviet leaders were ruthless but rational. They were acting from a position of national strength because even back then nobody was disputing the incredible sacrifice that Russia had given to the effort of defeating Nazi Germany. Whatever fear and loathing there may have been between the West and the USSR, there was a common root of respect at that level. Putin's generation can not rely on that respect. He is a post-war baby, or what we call the babyboomers. If anything, the young generation of every culture, including his own young people, is loathing people of his age. He is a parasite in a country that desperately needs a real leader. Nobody will shed a tear when he is gone. That is why he lashes out. His will only be remembered for the harm he has done to Russia and others.

  8277. Why do I need to pay $75, anyway? Google's free Gemini 2.0 Flash Thinking Experimental is now giving satisfactory answers to a number of problems AFTER being helped with the correct answer, i.e. it can at least learn during a session. It is, however, still giving the wrong answers on its own. In other words... I now have free access to AI that may be teachable enough to be useful IF we assume that on its own it messes up 100% of the time, which for my test problems it does.

  8278. Prosperity and age are two independent dimensions, which complicates the problem. The young didn't get rich in Japan, either. There is quite a bit of existential dread among the younger generation (same in Europe and the US, by the way). China is experiencing a similar development, except that it is even more exaggerated by its regional development. There is a very small number of (now mostly elderly) people who grew rich or at least semi-prosperous in China, but both the younger generation in the cities and pretty much everybody else outside didn't participate in this development. What compounds China's problem is that it has now geriatric leadership for life. The only way that Xi Jinping knows how to get prosperous is the very way that doesn't work any longer.

  8280. Boring. This argument has been made half a century ago and it wasn't true back then, either. Not even a simple ice cube melts immediately when heated. It takes a while for the ice to get close to the melting temperature. Only then does the melting start. Thermodynamics necessarily causes delays and non-linearities in the response to added heat.

  8282. Pretty similar to a couple of years ago. The technological problems are still hard and the main question, how to translate a classical algorithm into a quantum algorithm efficiently, has still not been answered. My personal guess is that it's the latter problem that will severely limit the applications for quantum computing. We will most likely find that correspondences between the two realms are far and wide between. That won't make quantum computing obsolete. Quite the opposite, but it will mostly limit it to a range of scientific applications in which we are explicitly asking questions about quantum systems.

  8300. There are no issues with quantum mechanics. Quantum mechanics derives directly from Kolmogorov's axioms describing ensembles of independent systems and relativity. Kolmogorov is about as trivial an assumption as one can make and it is completely independent of any notion of spacetime. Relativity is obviously at the heart of general relativity, which is the best theory of gravity that we have. So, no, it's not a problem in that sector. We may have a poor idea about the microscopic structure of spacetime, but if that's the case, then general relativity breaks down and Kolmogorov sticks around.

  8320. You have a completely false idea of how physics works. That Newton's result was only an approximation was already known to Newton. He wasn't even particularly happy with it for various reasons, it seems. We simply didn't have the necessary mathematical tools to derive a better post-Newtonian theory until roughly the time of Einstein, but even Cartan, a mathematician, was working on it. So there is really nothing "delicate" about this. This is simply standard modus-operandi of science. Classical unifications of gravity and electromagnetism are a waste of time, except for mathematical curiosity sake. We know that that's not how nature works.

It's what allows us to capture large amounts of energy with solar panels. The problem here is that you don't differentiate between the physical phenomenon (energy transfer) and the abstract description. All of mathematics is an abstraction of physics, by the way. We can start with Euclid, if you like. Lines don't exist. They are an abstract extrapolation of sticks or pieces of string. Logic is isomorphic to set theory, which is basically an extrapolation of objects in baskets. Math is just physics taken one step too far. It's fun, but it's not real.

He does it well, but within the limitations of how one can communicate physics to a wider audience. Most of the folks who are writing books for laymen are under the usual commercial pressure and they are human. Humans give in. When your editor tells you to water it down and to pep it up or to get out of his office because he can't afford to sell three copies of your scientifically precise horse tranquilizer, then you do what humans do. You go with the flow, which goes towards fake news, even in the laymen literature. Many worlds is a side show. There are fundamental problems in quantum mechanics, but not of the kind that many worlds is trying to cure. Anything that has to do with the double slit is bad physics, for instance, but unfortunately of the kind that is even being taught in undergraduate university classes. There are trivial things in every field that are just so cringeworthy that nobody even notices them any longer. They are just being retold to every new generation, which then adopts them without questioning. Unfortunately, that is the "salacious" material that makes it to the internet and into books and on tv.

In case of Schroedinger's cat QM makes the exact same prediction as classical mechanics: that we simply can't know what's inside a perfectly isolating, closed box.

  8378. There never was a measurement problem to begin with. A measurement in physics is always an irreversible energy exchange. In quantum mechanics this means we have to absorb a quantum of energy. Once we do, that quantum is gone. What people falsely call "wavefunction collapse" is actually just irreversible energy transfer. That decoherence doesn't solve the problem is completely obvious: it's not an irreversible process. It merely expands the state space of the system, but the new system stays reversible, i.e. we are just getting a new recurrence timescale. To have a true measurement we need true irreversibility, i.e. there can be no recurrence afterwards. The only way to achieve this is with an infinite phase space, which nature conveniently provides: it's the infinite physical vacuum.

  8391. That's how you walk when your muscles are weak or you are in pain. Since the machine is obviously not in pain it stands to reason that its actuators are still underpowered. I would guesstimate that it takes another factor of two in force/torque or more to get human-like walking and maybe a factor of five to get human athletic abilities. It's a non-trivial engineering problem but solvable over time.

  8395.  @splynncryth  There is nothing wrong with that. Back then we had Linux on PCs and it ran just as reliably as UNIX on five times more expensive hardware.

  8397.  @splynncryth  Why are you taking this so seriously, anyway? That Linux sucks is not your fault. You don't have thousands of professionals to make it work, either. A good OS requires a professional build team. Windows NT was initially built by approx. 200 people, I believe. By the time they were shipping that number had swelled to 1200, if I remember an article about it correctly. That was a tiny system compared to the size of a Linux distro and it was a focused effort by people who were full time employees. That's the power of money. It can create actually working operating systems. Neither you nor I nor the entire Linux community has that kind of change.

Humans can't stay for long in higher orbits because of the radiation belts. Those are, indeed, deadly. We have to fly through them quickly and then we are safe again, at least for approx. a year without having to worry about excessive radiation shielding. Humans can also indefinitely stay on Moon and Mars because there is plenty of radiation shielding material available. All we have to do is to bring a bulldozer to pile up some dirt and the problem is solved for good. None of that is the problem. The problem is that Bezos has built the equivalent of a propeller driven plane that flies for the first time while Musk is almost done with the equivalent of an Airbus 380.

  8420.  @greghansen38  I didn't say that you needed to read up on interpretations. As you said, they are not useful. They are also not necessary. Nature gives you a natural physical interpretation in quantum field theory. The problem with "quantum mechanics for beginners" is that they are not actually teaching you real physics. The world does not behave anywhere close to what non-relativistic QM suggests. If you were to try to probe the location of an electron inside an atom with ever higher precision, for instance, then all you would achieve is to ionize the atom. If you then ramp up the precision of your measurement by another three to four or orders of magnitude, what you get is not one electron but pair production of electron-positron pairs. At a few hundred MeV of probe energy muons will pop out, then taus and eventually quarks and gluons and W and Z. We have no idea what cute stuff happens at 10TeV. Non-relativistic QM is not even a theory. It does not describe the world correctly except in a very narrow range of energies. It does have the advantage of being simple, but that comes at the disadvantage of being non-physical. Reality is much more complicated mathematically, but ontologically it's much, much less convoluted than non-relativistic QM suggests. That is what your teachers didn't tell you... they simply didn't know.
    1
  8421.  @greghansen38  Scattering matrices don't have ontological problems. They are describing the scattering of waves from infinity with the outgoing solutions also being probed at infinity. This eliminates questions like "what is a measurement" completely (not that that's hard to answer in non-relativistic QM but one has to drag thermodynamics into the mix, which is not necessary in relativistic theory). It eliminates the classical-quantum system boundary. Infinity always provides more than enough degrees of freedom for decoherence without having to construct "measurement objects". Phase doesn't matter at infinity, it all automatically boils down to amplitudes, just to name a few advantages. I do agree with you all the way that we are not teaching classical scattering theory nearly enough. It is extremely important in practice (optics, electromagnetic systems engineering, radar, medical imaging etc.) but the average physics student gets to see almost nothing about it. I certainly didn't, except for a trivial 2-d Coulomb toy problem. We also didn't learn relativistic dynamics enough to have a solid handle on collisions and high-boost systems. That leaves accelerator physics mostly in the dark, even from a classical perspective. I was taught some nuclear physics, but basically all in the non-relativistic approximation. High energy physics? Forget about it. That, however, is the real "footprint" of the universe. OK, it would have been different at a university that had an active high energy physics program, but even those lectures (I took them later as part of my PhD) were kind of very basic and insufficient to understand QFT on more than a surface level. One can, of course, learn important lessons about QM from atomic, molecular and solid state physics, but the fact that we are teaching the formalism independently of its applications makes connecting the dots harder, IMHO. I hope that younger professors are slowly getting a better handle on how to give students a working knowledge of QM, because for sure mine didn't.
    1
  8422.  @greghansen38  How does scattering hide the ontological problems? Do your eyes have ontological problems seeing? Is the sun in a quantum superposition between day and night when it shines? Of course not. By referencing everything to infinity you have a perfectly classical reference surface because it has an infinite (i.e. large enough) number of uncorrelated degrees of freedom that will disentangle all physical observables for you. No such thing can ever exist in a closed volume. In a closed volume we are always running into the recurrence problem, which is no different from classical physics. Infinity is and always was the solution to recurrence, to statistical mechanics and it is the solution to quantum mechanics. People are just so afraid of it that they desperately try to remove it from their systems, which necessarily ends in inconsistencies. Nature doesn't have that problem. It even gave you an expanding universe to make absolutely sure that there is a true event horizon at a finite distance in which absolutely everything disappears without ever coming back. The perfect MS Windows waste basket. Absolutely spyware proof. Use it! :-)

  8432. The consistent theory is called "general relativity" and the parameter that plays a role in there happens to have the units of energy density. You are correct that homogeneity is, as of now, an assumption. Not much changes, though, if the universe is not completely homogeneous. The basic effects stay the same.

  8435. His personal opinion in this matter is irrelevant. He couldn't give support to Ukraine without the permission of the federal government even if he wanted to. I am kind of sure at this point that he probably can't withhold it, either. They probably told him that non-cooperation with the federal government will have serious consequences for his companies and probably even his person. That there is no love lost between Elon Musk and the Biden administration should be pretty obvious. Biden didn't even acknowledge Musk's critical role in kicking the global EV movement off, which was very petty, to say the least. Musk is who he is, but his accomplishments should be judged fairly, especially by democrats who claim to be truth-loving people. Unlike Trump Musk seems to be paying his taxes, as well, so he is not even a bad citizen. He rightfully complained about purely emotional attacks by key democrats on his person. On some level I can even feel his pain. I am not saying that I want to be associated with him in any form (and I am not), but he will probably become one of the most tragic public figures in the 21st century if he keeps going down this line.

  8441. The simple explanation is that quantum theory does allow for chaos just fine. Quantum chaos has been observed on atomic systems in the lab in the 1990s, latest. It was quite a popular field back then. Sabine simply didn't read the literature on the topic. You are, of course, also correct.

  8447. There is a lot of demand for the system, just not in long distance travel. You can take pretty much any metro-area of the world and you will see that the limits of expansion of suburbs is given by commute times. If you want to have connect to suburbs that are more than roughly 50 miles away, then you need to have a fast transit system. Hyperloop running at e.g. 400mph in a tunnel can connect in a quarter of an hour without any of the right of way penalties that come with systems above ground.

I have never met a self-taught guy in my life. Most of the CS and IT people that I met at my jobs were from MIT and other top schools. I have worked with one military vet who got his degree from the army. He was a really great engineer.. underappreciated, underpaid because he didn't have a degree from a major university.

Today we classify quantum mechanics as the unitary representation theory of the Poincare group. As soon as you can unpack that sentence you will understand absolutely everything about quantum mechanics and it will become completely trivial to you.
    1
  8482. That's because both trains of start out with a trivially false assumption in addition to what the actual theories say. That assumption comes from a popular simplification among theorists who prefer closed to open systems. If you actually look at nature, however, then you will find that all systems are open, which has profound consequences.

It's the most native thing you can do on any current platform that has a browser.

  8601. Yes, it would be if you are approaching it from the mathematical side, which tells you very little about physics. I would suggest you try to understand the physics, first, before you learn the math. That makes it a lot clearer what is going on. Quantum mechanics is about quanta of energy that get exchanged between systems. It is NOT about objects. It is NOT about particles and it is NOT about waves. When systems exchange quanta of energy, they also exchange momentum, angular momentum and charges like electric charge or leptonic charge. Energy and momentum are not quantized, but angular momentum and charges are. They only come in integer multiples of a minimal quantity (usually expressed in Planck units and electron charge, but these are arbitrary numbers due to the choice of our units - in rational units they should be set equal to 1). In an experiment the detection of one quantum is basically one "click" of a detector. In the ideal scenario such a detector can tell us where and when a quantum was detected and how much energy, momentum, angular momentum and charge it had. A single detection carries basically no relevant physical information about the systems that emitted these quanta, so we have to bunch an infinite number of them into a quantum mechanical ensemble and then we can form frequentist counts aka histograms aka probability distributions with them. Because we are now working in an ensemble theory, we can assume that each member of the ensemble is isolated and that means that sub-ensembles are statistically independent of each other. This leads to the usual Kolmogorov axioms for probability theory. It turns out that these axioms for statistically independent ensembles can also be satisfied with complex and quaternion based functions (and probably product algebras built from these basic elements, but that's less often used). The resulting functions are normalized elements in Hilbert spaces (normalized because the number of members in an ensemble does not change during the evolution of the ensemble), which basically leads to unitary dynamics, i.e. rotations in finite and infinite dimensional linear spaces. In the trivial finite dimensional case these rotations can be described by Heisenberg's unitary matrices, in the infinite dimensional case we need linear operators and partial differential equations. And that is basically what quantum mechanics is: the theory of unitary rotations, except that there is not much physics in that because that part is basically a simplifying assumption (that all the copies of the system we start out with are still there when we detect the results). In experiments that's far from true. We actually lose most quanta of energy in most of our experiments. The experimentalists are simply fudging that loss with an arbitrary (experimentally measured) number that we call "quantum efficiency" and the theorists never get to see that fudge, so many of them think that "unitarity" is some god-like property of quantum physics. It's nothing like that. It's just what's left over after the experimentalists have cleaned the data. If you keep that in mind you will start to understand why the mathematical structure of quantum mechanics is so meaningless. It's an artificial construct, not a property of observational reality. It has that in common with Hamiltonian mechanics, but that's another rant. ;-)

  8611. The simple explanation is that you aren't thinking clearly and you weren't paying any attention in school. We show the double slit with water waves in high school. Where do you see photons in water waves? We also demonstrate that interference is the absence of self-interaction in linear waves. Interference is NOT a physical effect. It's the absence of a physical effect. ;-)
    1
  8612.  @Qichar  The pattern with water waves is also aligned perpendicular to the slits. This has nothing to do with the detailed nature of the waves. It holds for scalar, vector and tensor waves. Why? Because it is a feature of the geometry of the double slit. We even derive the result for you in Frauenhofer approximation in school and all it needs is a little bit of geometry. Nowhere does it need Planck's constant or even angular momentum quantization. Light is not a wave at the quantum level. It is the excitation of a quantum field, but the double slit does NOT demonstrate the quantum level. It demonstrates only the mean field theory and the mean field theory of light IS a wave theory. At the level of de Broglie you are still talking about waves because you are still not exploring the full consequences of angular momentum conservation. At least Planck's constant shows up, already, but it already did that in the Planck spectrum. The fully quantized theory only becomes visible in things like the hydrogen spectrum.
    1
  8613.  @Qichar  Photons are small amounts of energy. They are not objects that the field is made of. These amounts of energy also depend on the measurement system, so they do not already "exist" in the field before the actual measurement is made. The field has some energy, but it is not atomistically made out of these bits and pieces that we just pick up at the end. Instead the measurement process itself selects how much energy it absorbs and where and when that absorption happens. Intuitively that's probably the hardest part to get used to. If you want a game of luck analogy, imagine a game of roulette, but the player decides which kind of wheel he wants to play with. He can get a wheel with 37 positions like in the standard version or he can pick one with just four, or another one with 19 possible outcomes. In quantum mechanics the choice of measurement is equivalent to the wheel the player would pick in the roulette example. You also have to let go of the idea that photons interact. They don't. Quantum mechanics is a theory of statistically independent ensembles in which every single outcome is completely independent of all other outcomes. There are physical systems for which this assumption holds (like the free electromagnetic field) and then there are systems for which it does not hold (and that's experimentally testable!). In the latter case the formulas of standard quantum mechanics do not apply. One can construct formulas even for that case and the first example of such a system that I am aware of was given by Mott in the year 1929. The problem with the way we teach quantum mechanics is that we do not mention these very important assumptions about the theory, which leads people to speculate about completely irrelevant things like "single photon interference". There is simply no such thing. The theory rules it out explicitly in the way it is constructed and the reason why this works is because the electromagnetic field does not interact with itself measurably at optical wavelengths.

  8638. It's just a coordinate transformation. Objects don't change their lengths. They don't even appear to be shorter. In reality they would appear slightly rotated and distorted.
    1
  8639.  @johnnyragadoo2414  The problem with the Lorentz transformation is that it is only valid in one point. This means that naively applying it to two different locations is already stretching the limits of its meaning. Any two different points in spacetime are always separated by a length AND a time difference. We can, of course, use the clock synchronization scheme suggested by Einstein to "distribute" a global time value across an extended coordinate system and it is that procedure that makes things appear longer or shorter. I question the physicality of that procedure somewhat, even though it leads to "fun" numerical effects like the barn example etc.. In reality, though, if you look at something moving at relativistic speeds, there won't be any shortening effect. The time it takes for the light from that object to reach us negates the Lorentz contraction.

  8646.  @nostoppingit7243  Is achieving national security goals worth a loss of stature among some members of society who are holding false liberal beliefs? I would definitely say so. There is a difference between humanism and a tolerance for political terrorists that are chasing an impossible goal using inhumane tactics against both their perceived enemies and their own people. Humanism values all life, but it values the lives of the innocent bystanders much, much higher, than the lives of the combatants. Humanism is also practical, which means that it does not exclude the possibility of collateral damage and it assigns personal responsibility. Each and every individual, including the innocent bystander, has a responsibility to leave zones of potential collateral damage. If they refuse to do this, then they have a measure of personal responsibility for the outcomes. The Palestinian people had 75 years to either leave the region or to integrate peacefully and defuse the region. They wasted every possible and impossible offer that was made to them to achieve a realistic level of personal freedom and security. No serious humanist will lift that responsibility from their shoulders at this point. If you are still there and you are suffering, that's almost entirely on you now.

  8647.  @sxmaia1224  You don't fight against a power that is much stronger than you are. You run away and you start a new, happier life somewhere else. Fight or flight is an honest choice that nobody has to be ashamed of. Palestinians could have raised three happy generations since the founding of Israel. Instead they raised three unhappy ones. That's a waste of human potential on a grand scale.

I went to one of the best high schools imaginable (half a century ago) but there was this one teacher who simply could not control a class. He was soon replaced. Every other teacher knew how to deal with us. It's just technique. And no, there was no corporal punishment. The teachers simply sent the worst behaved kids who wouldn't cooperate to the principal's office. I was told by a teacher that the guy was absolutely brutal in the way he would dress you down psychologically. I am not aware that anybody ever had to go to his office twice. You got that treatment once and you were done for life.

There is a multi-million person backlog in the family based immigration system. If we add the 10+ million illegal immigrants to the cue, then Congress would have to triple the number of current legal immigrants just to restore just the status quo by the end of Trump's presidency. I don't see anybody touching that political third rail and Trump has no authority to raise those numbers as far as I know. Not to mention that there is no civil service workforce to actually handle that kind of immigration backlog. This is the democrat's plan, by the way, that has been rejected by republicans for decades.

  8754.  @angrydoggy9170  These aren't military coups. Not that the French revolution made anything better in France... it just imposed a different kind of terror on the population... an intellectual kind that saw fear as the absolutely necessary cleansing tool. That's basically a sadist's fantasy. It is true that it ended in a military coup by Napoleon, a future Emperor who dreamt of world domination who couldn't be defeated except by a military (but not so much political) coalition of the remainder of Europe. The US revolution was essentially a white land owner's anti-tax movement that didn't mind writing slavery into the constitution, which it couldn't get rid off in any other way than by a bloody civil war that is still reverberating in at least half the hearts and minds in this nation. The idea of the common citizen as a soldier brought us the second amendment, which has made the US one of the most violent nations in the world. Please, let's stick to the facts here.

  8758. OOP is mostly documentation. Compilers strip all the object information from the code. Your main goal in writing object oriented code is to tell other programmers what you are doing. The second reason is that OOP prevents you from using the wrong methods on incompatible data. You are basically telling the compiler to stop you from shooting yourself in your own foot. Having said that, if you get your object structure wrong, then gunning at your feet is exactly what you are doing because now you have to constantly refactor. If you don't know these things, then you are simply not qualified to be a programmer.

  8778. Single photons do not show interference. It takes a large number of them to see interference patterns. Interference is a pretty bad terminology to begin with. Interference happens in linear systems in which parts of the system do not interact with each other, at all, i.e. interference is the absence of all physical effects, not a physical effect itself. More properly it would be called "non-interference". It is amazing how few people understand this fact intuitively.
    1
  8779.  @neillibertine3044  Like I said, a single photon does not produce a measurement that even shows interference. In an interference experiment we need, at least, two measurements. On dark stripe, one bright stripe, for instance. That's a non-reducible number (and it will give very poor statistics). None of this has anything to do with interaction. Again, it's the total absence of interaction that causes this. In quantum field theoretical terms, if you want to have a self-interacting theory, then you have to have, at least, a phy^4 term (phy^2 is just the energy of a linear field). Light, at least at optical frequencies, is completely without self-interaction. The lowest order photon-photon scattering process is a four-photon gamma_1 + gamma_2 -> gamma_3 + gamma_4 process, which is suppressed by some 50 orders of magnitude for ordinary photon densities in optical light sources if I remember correctly. It's a very hard experimental challenge to make free-electron gamma sources and femto-second laser sources that can actually produce these non-linear interaction between photons without the use of electrons or other charged particles.

  8782. A quantum is "a small amount of energy", i.e. the noun "quantum" already describes a change in a property. The adjective then describes scenarios that describe or are based on changes of properties.
    1
  8783.  @martf1061  Energy is a system property. A quantum is just a small amount of it (compared to the human sized "Joule" scale). There is nothing here that we didn't explain in quite some detail at the high school level, it just happens that people don't realize that it's exactly the same as mechanical energy exchange because there is so much unnecessary noise about it in the "public science" arena.
    1
  8784. Not a bad article, as far as the mathematical implications of the formalism are concerned, but it still misses the actual physical ontology, which is not surprising. It was written by a capable theoretical physicist. He thinks in terms of formalisms, rather than the physical systems that the formalism stands for. He gets a lot of things right, including the time scale separation in Schroedinger's cat, but that already happened at the level of the nuclear decay that drives the experiment, so he misses that the "cat is alive" criterion is a mere garnish on the actual physics that has already happened long before we ever get to that level. That's the same physics that Schroedinger missed to understand because he was not a nuclear physicist. It is also obvious that he still can't distance himself from the particle picture, which causes most of the confusion among laymen. It is, in some sense, useful among high energy physicists like himself, because detectors are measuring high energy quanta with weak measurements, which leads to particle-like effects, but it is completely wrong in e.g. quantum optics experiments with optical photons, which comprise the large majority of "mystical" experiments.

  8803.  @ssergium.4520  Superdeterminism is trivial bullshit. A simple look at a spacetime diagram can tell you why. Now, why was determinism always bullshit, as well? Because we always knew that the future was not predictable. People never stopped playing games of luck. Not after Newton, not after Lagrange and not after Hamilton. We are still playing the lottery. Why would we do that if we knew that the future is completely determined? So, if the future is not determined and the world is causal, what does that mean for the present? It means that the present is uncertain. Guess what quantum mechanics tells us? It tells us that the present is uncertain. Easy, right? ;-)

  8821. That we don't care about antibodies is simply not true. This is a fast multiplying virus. A high antibody titer means a fast response to an infection, which means a low peak of viral particle count before the immune system can limit the disease. Without those antibodies the B- and T-cell response takes considerably longer, which leads to a much higher viral particle concentration, which makes the person both more infectious and more sick. There is so much false information about the biology of this out there that we might as well talk about the birth of a new religion. People are looking for a new resurrection here. There is none. Hospitalized patients are still dying in large numbers and that won't stop with the end of this wave, either. It will continue periodically as the antibody counts in people decrease after vaccination and/or infection. We can either actively eliminate this disease completely or it will be with us for a long time. Why people don't get this is very hard to understand. We all had the flu and the common cold regularly in the past, didn't we? What is, supposedly, the biological difference here? I mean, other than that this is a much more deadly disease?

  8835. I have been watching the Palestinian problem since I was young. My final and ultimate impression about the Palestinian people was the massacre of the Israeli Olympic team by a Palestinian terror organization in 1972. I have not shed a single tear for Palestinians since. I am not shedding one now. Terrorists are betting on the fact that their actions are leaving marks on people. Well, that bet is correct. They left a mark on me. I am a humanist and I value life, but I do distinguish between innocent life and terrorist life. I value the first, I do not value the latter. The Palestinian people had many decades to stop being terrorists. They never did. They consistently groomed their children to become future terrorists. This was unnecessary and a grave mistake. Grave mistakes have grave consequences. These consequences are materializing now. So, no, I do not mind my taxpayer dollars being used for bombs that are hitting centers of international terrorism like Gaza. Would I have preferred a peaceful solution? Absolutely. Did the Palestinians allow for one? No. And that, I am afraid, is that. Yes, I can watch as "innocent children" are dying and not shed a tear. And to every wannabe terrorist I say this: Do NOT assume that we are running out of either bombs or cruelty.

  8872. Depends what you mean by WIMP. We have not found certain kinds of WIMPs. That doesn't rule out other kinds. The problem with the standard model is that it predicts too much. We can come up with all kinds of fields that have all kinds of properties. We can certainly come up with fields that would be nearly undetectable at thermal energies but still gravitate (try to detect thermal neutrinos... good luck with that!). That's a bad way of doing science, of course. That's why we need high energy machines because at high enough energy even the weakest of interaction becomes a major effect. We wouldn't even have to find WIMPs. We could end up with observations beyond e.g. 10TeV that would actually rule out WIMPs of the kind that cosmologists would like to see. So that would actually be a boon for modified gravity. Science is empirical. Without actual observations there is no science. There can only be theology and philosophy and both are useless.

  8883. What answers are you disappointed with? The determinism question? That has an absolutely trivial answer but you are asking the wrong guys. Neither philosophers nor biologists have a good handle on it. It's the physicists who do. The trivial answer is that the world is not deterministic. It was never deterministic. For the longest time humans couldn't make any sense of the world. Most processes seemed confusing, at best, and random at worst. Eventually we made a little bit of progress with Newtonian mechanics. Suddenly we could answer questions about the trajectories of single objects. We could, in particular, predict the motion of a planet from first principles. That was the major scientific breakthrough of the 18th century. It was so huge, indeed, that people were immediately over-extrapolating it. If one could predict the motion of one planet with absolute certainty, then shouldn't it be possible to use the same methods to predict the motion of absolutely everything else? That is the idea that lies behind naive determinism. It is as obvious as it is false. Newton himself already noticed that he didn't get anywhere with his methods when he was contemplating the notion of two planets that are interacting with each other. Today we know with absolute mathematical certainty that this motion is NOT predictable. The three body problem is, in general, not solvable. Hard determinism does not apply to it. It's far worse, actually. We know that among all possible systems in Newtonian mechanics (of which there is a very, very large infinity) only a handful are deterministically predictable in the sense of 18th and 19th century determinism. Every other system does not behave in a way that would allow us to predict its long term future. It gets much worse if we try to apply determinism in special relativity and quantum mechanics. I will spare you the details, but 20th century physics knows that the future is open. It is not only unknowable to us but it is, in general, unknowable to nature. Nature simply doesn't care to pre-select one possible future from all possible futures. It doesn't operate in the way 18th century thinkers imagined. In other words... everybody who is still hunting for determinism in science is hunting for a snark. It's simply the wrong way to think about nature, on all levels, small and large.

  8884. Testing for testing's sake is completely irrelevant. It only appeals to people who have OCD and can't stand it that not everything in life is perfect. The only relevant metric is how much covid stresses the healthcare systems and that, of course, is always known precisely.

  8885.  @LJ-wo1wf  Whether the numbers are rising or falling can be easily seen by the ER triage nurses. Again, unless you are testing to prevent future infection by others, which most people don't do because they don't really give a frell, then testing doesn't do a thing.
    1
  8886.  @LJ-wo1wf  Nobody "needs" the test results. You need to get tested before you get on a plane. That will reduce infections somewhat. Truthfully, even for that purpose you would have to test negative, then quarantine for three to five days and get tested, again, to make sure that the plane is covid free. Testing for testing's sake is magical thinking. There are, unfortunately, a lot of three year old magical thinkers around.

  8903. A psychopath is not a crazy person. They simply don't feel empathy for others, but that does not mean that they aren't acting rationally. Putin grew up during the Cold War, so he knows exactly what nuclear weapons can do... and what they can't. Putin may also know, or at least strongly suspect, that Ukraine is a nation that has nuclear weapons. It was, after all, holding a large part of the stockpile of the USSR. Anybody who believes that all of the weapons that Ukraine had after the USSR broke up were completely accounted for probably lives on Mars. It is highly likely that there are at least a few working low yield and dirty bombs in the possession of Ukraine. The scrambling actions of the Russian military in Chernobyl and other nuclear facilities are indicative that they suspect that Ukraine has a secret nuclear program going that has yielded some "useful" results. Russia can't risk going all in. I believe it's really that simple.

It was only under extremely lucky environmental and social conditions that mankind could deputize some of its members to artistic and scientific activity. It wasn't until the modern age that the majority of our economic activity could shift from food production to other kinds of productive work. If you don't understand these trivial economic facts, then it's not surprising that you happen to think that Marx was smart. :-)

Even temporal boundaries require energy in form of the energy reservoir of the clock measuring the time interval between the beginning and the end of a system or experiment. How little energy we can find in a system is therefor an experimental choice. The universe certainly doesn't seem to be afraid of a bottomless pit. ;-)

  8951. I do like modified theories of gravity a lot, actually. They would be far better than conventional gravity if we want to have any chance to learn anything substantial about quantum gravity experimentally. The problem is that the versions that have been suggested so far don't seem to fit the data very well. That is no different from the suggested dark matter fields, of course. The main reason why many theorists on the high energy physics side of this prefer dark matter fields is because we have a suspicion that there is a whole lot of "heavy stuff" beyond the 1 TeV scale. It would solve a lot of detail problems that are unsolved in the standard model if there was a dark sector. Dark matter fields would therefor solve two seeming independent sets of problems at once. Independently of what preferences we have, the scientific method requires us to exclude all possible hypothesis one way or another, i.e. one can not stop searching for either MOND gravity theories or dark matter fields. That's simply not how science works.

    1
  8957.  @5thElem The engineering role of functions is the same as that of loops: they are code reuse. Instead of replicating the same code endless times (which would be mathematically equivalent), we use the same code to act on different data. Other than that they are irrelevant to the operation of software. A good compiler will perform loop unrolling and function inlining automatically these days. In other words... whatever the programmer writes will be translated into a better performing machine code equivalent anyway. Let me give you another important tip about side effects: the only side effect relevant to your boss is how much money he makes with your code. How you code and what religious beliefs about coding you hold are entirely irrelevant to him. Your main role as a software engineer is to make money for the company. Unless you understand that, you don't understand anything about what you are doing. :-)

  8987.  @Number6_  Absolutely. Her point and mine is simply that there is very serious research into the domain boundaries of general relativity. That has nothing to do with the trolling crazy folk that just can stomach relativity. We know from theoretical considerations where general relativity has to break down. The problem is simply that that's very, very far removed from the experimentally accessible physical regimes, right now. That, however, does not mean that we don't have to scan the accessible range as far out as we can. If you look at general relativity structurally, for instance, there are plenty of mathematically possible alternatives that behave just like Einstein's theory in the known range but deviate from it on an intermediate range to the Planck scale and possibly even over cosmological distances. We therefor have to perform experiments and observations that rule these alternative models out. That's just how science works.

  8998. Einstein didn't have difficulties with entanglement. He had difficulties with the interpretation. In a sense he was right because non-relativistic quantum mechanics is not a physically meaningful theory in itself. It's a toy model of the real theory, but that theory was not available to Einstein in the 1930s, yet. It would take another couple of decades before relativistic quantum field theory, which is a self-consistent theory, would be sufficiently developed. Einstein died in 1955, only a few years after the first rough drafts of modern QFT were finished. I am not aware that he was still interested in quantum mechanics at that late stage of his life. And, no, there are no particles. That's just bullshit you picked up on the internet.

  8999.  @gargamelandrudmila8078  You are correct about that, but it's time for the particle bullshit to die. We need to teach people the difference between atomistic matter and quanta of energy.

Kid, you need to get an education. ;-) At CERN there were approx. 8,000 PhDs and students working on one of the detectors and a similar number on the another during the peak of the construction. A smaller but still significant number of PhDs was needed to design and build the accelerator and support infrastructure. I would estimate that in total close to 100,000 academics (mostly PhDs and engineers specialized on scientific hardware) were needed for those experiments from start to finish over the over 30 years that LHC has been in the planning and running. If these are "small numbers" to you, then you have absolutely no clue what you are talking about.

  9013. I can easily make an experiment in which I can't be manipulated, not even by myself. I throw dice. Even I go left, odd I go right. My "decisions" have nothing to do with my actions, but I have still subjected myself to the decision of the dice out of free will. A more practical example are algorithms. We let a computer make a decision for us based on some data that we may not even be aware of or that we chose not to look at ourselves.
    1
  9014.  @Ma_X64  You don't have free will. All you have is agency. That's not the same. If the dice had "free will", then they could show 3.14159... on occasion instead of 3 or 4. That can't happen. They do have agency, though, which means that their outcome correlates with some particular future (the 1-future, 2-future... 6-future). In classical determinism this future depends entirely on the past, which makes the present asymmetric. In quantum mechanics, however, the present is symmetric. It depends just as much on the past as it depends on the future, i.e. no amount of navel-gazing about what came before us can tell us what will come after us. What causes this symmetry? Relativity. The energy that leaves "the present" on the forward lightcone moves at the speed of light, i.e. it can not be "caught" by any local physical mechanism. It disappears into the deep future in just the same way as some of the energy that drove the present came from the deep past. So while there is correlation (entanglement) between the past and the present, there is also correlation (entanglement) between the present and the future. That's why what we do here and now has consequences that are not just a function of the past alone.

  9017.  @A.Raybould  I still don't see it. There is a 50% chance that a live bomb goes off, one way or another.
    1
  9018.  @eljcd  The dud bomb in this case is basically a bomb that's not in the light path. Of course a bomb that does not receive a signal does not go off. That's a completely classical result.
    1
  9019.  @A.Raybould  I am not seeing non-classical behavior by the bomb. It goes off every time a photon is detected by a live bomb. It does not go off when a photon is not being detected by a defective bomb. What is strange about that?
    1
  9020.  @A.Raybould  We can make a bomb that has an electrically operated lever arm with the photodetector on it. When the battery in the bomb works, the detector is in the light path. When the battery is empty, then the arm drops down by gravity or using a spring. That way "the detector" is completely transparent when the bomb is "off". Of course the detector is classical, the level arm is classical, the trigger is classical and the explosive is classical, i.e. even this Rube-Goldberg bomb is an entirely classical system. Every time it is hit by light and is on it explodes. No amount of quantum magic around it will ever change something about that. You are correct that without this mechanical lever the bomb's detector would always absorb photons and then the entire experiment would be completely ridiculous.
    1
  9021.  @A.Raybould  A photon is an irreversible energy transfer between the quantum field and an external system. That process is classical. What is not classical is the energy propagation within the field itself, but then, there are no photons in there, to begin with.
    1
  9022.  @A.Raybould  I am simply giving you a detailed model of how to build such a quirky detector and why it is entirely classical. It is, at no time, in a quantum superposition.
    1
  9023.  @A.Raybould  Quantum mechanics doesn't tell us anything about paths. In order to measure a path we would have to make at least two consecutive measurements on the same physical object. That is not possible with quanta. As soon as we measure a quantum it is gone. More precisely, the quantum only "exists" during the measurement. Before it is field energy and thereafter it is thermalized energy in the "detector" system. I am a physicist. As a matter of principle I don't "imagine" things that can not be measured. That procedure, I am afraid, belongs into religion, philosophy and creative writing. What I am saying is that none of these parlor trick experiments teach you anything substantial about quantum mechanics. The realization that quanta are, in some sense, monads of energy, does.
    1
  9024.  @A.Raybould  I know that the video talks about paths. What I am telling you is that videos that talk about paths of quanta are confusing you about what quantum mechanics is. Yes. If the bomb goes off, then the energy was deposited in the bomb's detector. If it doesn't, then it has to be deposited either in A or B. What did you learn here? How to make a Rube-Goldberg machine to demonstrate energy conservation? How to attract more people to a physics video by talking about a bomb instead of detectors A, B and C?

  9027. Nobody has ever seen an electron in superposition. What is in superposition is an abstract mathematical quantity that describes our knowledge about an unmeasured quantum mechanical ensemble. The individual measurement is always a perfectly classical amount of energy, momentum, angular momentum and charge. We call those amounts "photons", "electrons" etc..

  9028. We probably do, we just don't know it, yet. So far everything in physics could be derived successfully from the relativity principle, which goes back to at least Galileo in 1630. Your lack of science education is showing. Tuck it back in. It's ugly and this is a family restaurant. :-)

  9029. China hasn't achieved anything negotiating either with the Trump or the Biden administration, though. My expectation was that there would be a serious change in relations, but there wasn't, which indicates that Chinese negotiators must have made a serious mistake talking to the non-political employees of the Department of State. I tend to believe that somebody in the Chinese administration, most likely the upper ranks of the CCP, came to the wrong conclusions about the internal dynamics of the US government. That is a hard mistake to undo, if it can be undone, at all. The US seems to have decided to play a long game with China, which China can't win. China is aging rapidly. By 2050 it will be as geriatric as Japan is today and we know how that is playing out economically for Japan. Technologically China will always be limping behind, not because it couldn't do better but because it has a me-too leadership style. China's only hope was to elect young and dynamic leadership but it opted to make Xi emperor for life. An aging country with an aging head of state... when did that ever turn out well? The good news is that Chinese are very long lived, so Xi will be at the helm for, at least, another 30 years. ;-)

  9061. String theory is to general relativity what quantum field theory is to special relativity. It has to be explored for mathematical reasons alone. That exploration turned out to be quite involved and it didn't deliver anything breathtakingly new from a physics perspective. I hindsight one can probably see why, but hindsight is always 20/20.

  9062.  @henley7012  Just how much, do you think, is labor worth these days? Not much and it's getting worth less by the day. That's not a new thing. If you can't adapt to technological progress, then you won't have much of a future, I am afraid, billionaires or no billionaires. In any case, the billionaire who employs you pays his own taxes and yours, since you are not supplying your own salary while you work for him. Think about that for a while.

  9063.  @henley7012  Elon Musk doesn't want to employ labor, comrade. He has said more than once that he wants to get rid of almost all the workers in his factories and he is very hard at work to make that happen. You aren't even listening. In any case, only idiots argue with success. Don't be an idiot, comrade.

  9064.  @ALL_CAPS__  Apologies. Yes, paying for the services one receives is the honest thing to do. I wouldn't even frame it in patriotic terms. It's a business transaction between the individual and society. We usually call it a social contract, but it is, at the end of the day, a service agreement. We protect you, educate you, help with food security and healthcare and in return you pay taxes once you are a healthy, productive adult to provide the same level of services that you were given to others. Social security isn't mooching, but I am pretty sure the comrades who are so "critical" of billionaires have done little themselves to pay into the systems that support them. The fact is that a guy like Jeff Bezos employs a million people and a a half. We can be critical about the quality of the jobs he provides, but he does provide jobs. We can be critical about Elon Musk's "hobbies", but he has done more than most individuals to propel the world into the 21st century. We haven't seen this kind of active, future oriented action in a long time. Critics of it have to ask themselves what they have done to make the world better, or, at the very least, what they have done to change the world. Wolff and his ilk are, at the end of the day, mothing but reactionaries. They have absolutely no ideas of their own and the ideas they promote have been shown by reality to be destructive beyond belief.

  9073. All time is the measurement of the observer. Time is simply that which the clocks show. The assumption in Newtonian mechanics was that all clocks are equal and that they are showing the same time no matter where they are and what their physical history was. That turns out to be false. The times that clocks show depend on their locations and relative motion histories. Nothing really exciting here.

  9080. Yes, but an intelligent person might consider that while Elon Musk talks about Mars a lot, maybe that is not exactly where SpaceX is really going. Not everything a person says has to be taken for granted. One can be skeptical about these kinds of statements. That doesn't mean Elon Musk doesn't know exactly what he is doing there... it's just not "going to Mars". That's just a front for something far more sinister. The world is currently in a new cold war and a new nuclear arms race which will include nuclear weapons in space as a fourth element in addition to the classical nuclear triad. If you think about it... Musk doesn't even hide that, he just tells you indirectly by talking about the fact that Earth won't be a safe place any longer (and it basically hasn't been since the 1950s!)... exactly because of the things that he is doing for the US government.

  9084. What are your science teachers lying about with regards to drift velocity of electrons? It is, indeed, tiny. It just happens that energy is not being transported by the electrons. That is the actual misconception that even older EEs who are not familiar with electromagnetic fields and antenna theory are working with.
    1
  9085.  @joinedupjon  You have still not shown any evidence that teachers are deceiving their students about the drift velocity of electrons in conductors. That electrons are moving in conductors is correct, at least if we accept that we are dealing with semi-classical electrons rather than proper quantum field theoretical ones (which we simply can't teach to anybody who didn't go trough at least three years of theoretical physics at the university level beforehand). But that's where high school has to leave it. The explanation using Maxwell's equations and full electromagnetic theory is usually second or third semester theoretical physics in university (I think I did QM before I did EM, but that depends on when professors are giving the classes at a particular physics department).
    1
  9086.  @joinedupjon  The kids were 13? That doesn't sound like high school science. In my high school this was taught properly in 11th or 12th grade.
    1
  9087.  @joinedupjon  Why does it not make sense? You only need the full dynamic fields approach if you want to talk about energy flow at or near the speed of light. Neither static electric or magnetic fields or even quasi-static (magnetic induction) require deep insight at that level. I am not aware of any school system that does full Maxwell equations in high school. That's university level.

Plenty of people had two and three infections by now (including ten of my own relatives). So why is pretending that the opposite of reality is true hard work? You won't find any evidence for that statement to begin with, so you might as well just confabulate.

  9091. You are correct. There are no Newtonian center of mass forces acting, but there will be tidal forces which are causing the existence of the Roche limit even in weak gravity. In the current theory we are always contracting physics to one point and its tangent space, which is an approximation that oversimplifies the actual physics of finite size objects. We can, of course, calculate the correct magnitudes of these tidal forces even in that approximation.

  9094. Mars has gravity and minerals. It has a landscape that one might call home. A rotating cylinder in space is hardly a comparison to solid dirt under your feet. In any case, the entire idea that man moves into space in large numbers is pretty ridiculous. Transhumans are the species that can conquer space easily. When gravity, time, air, food and water have become obsolete and hard radiation is like a light rain shower, that's when space becomes a place to live in. When motion can be accomplished at the speed of light by copying oneself from one avatar to another, that's when the solar system becomes a playground. There is a hard way into space... that's what we are doing right now and there is the right way into space. Transhumans will take that road.

  9109. There is no mechanism. The problem is simply that you have been over-trained in school on causal scenarios. Everything that we taught you in K-12 was based on trivializing "If A, then B" logic. In this case, however, the chain of "effects" is caused by "NOT A, therefor B, C, D, E etc.". Almost all of modern physics is based on the profound consequences that the absence of physical interaction causes. All of relativity is based on the fact that spacetime is empty. All of quantum mechanics is based on statistical independence and the fact that relativity does NOT allow for communication between remote entangled systems. We can derive all of this perfectly logically using fairly simple math (quantum mechanics is basically a consequence of an appearance of Pythagoras in the theory of ensembles of statistically independent systems, believe it or not), but since we don't teach these derivations either at the K-12 nor at the university physics level most people are going off on intellectual tangents because they can't figure them out on their own.

I take the other two coins and send them to Bethany. Aretha looks at her two coins and finds that she has two nickels. She automatically knows that Bethany has to have two dimes. If she finds one dime and one nickel then it's clear that Bethany also has one of each. That's entanglement with coins. Not a problem.

  9119.  @davidhess6593  I didn't say that Einstein was right. A physicist being right or wrong about something makes no difference to nature. If you don't understand that, then you don't understand science to begin with. Entanglement is simply a local conservation law acting on a quantum system. What is the action of a local conservation law? Nothing. It simply does nothing to either energy, momentum, angular momentum or charge. What's hard to understand about nothing happening?

  9136. It is not the magnetic field but the electromagnetic field. The energy flow is given by the Poynting vector, which is the cross product of electric and magnetic field vectors. Since the electric field points (mostly) radially away from the wire and the magnetic field is circular around the wire, the Poynting vector is (mostly) parallel to the wire. There is a small component that points into the wire... that's the heating due to Ohmic losses.

  9138. At least that's the theory. In practice it leads to either endless restructuring or to creative workarounds. Redundant code was a great argument in the deep past when OOP was invented (the 1960s). At that time your computer had 32kWords of memory, so you really, really wanted to squeeze the last byte out of your code. Today your computer has 16GBytes or more and there is absolutely no significance to code size optimization. You will NEVER write that much code to begin with. Almost all of your memory contains data and not code.

That's just stupid people talking bullshit on the internet.

  9162. It does when you are on an FTL ship, but that's because the diagram is actually wrong for that case. The light cone gets narrower as we approach the speed of light and it contracts to the diagonal as we reach it. That's the famous "light does not experience time" case. However, if we evaluate it past that speed, then the cone doesn't start opening up, again, instead if flips 90 degrees out of the diagram. Time becomes imaginary. That's tachyons. Tachyons are not experiencing time because they are constantly decaying. There simply is no FTL coordinate system in which stable matter can exist.

  9183. You are partially right. Where you and everybody else gets it wrong is the national debt debate. There is no such thing as "national debt". This is not money that will ever be repaid. It is simply the creation of more liquidity that allows the international monetary system (that is based on the US dollar) to function. Along the way of creating that liquidity the US government simply collects a one time, 100% tax on the money it puts freshly into circulation. It uses all of it in a way as if somebody had already created taxable income with it. If we wanted to get a similar effect from taxation, we would have to generate something like six times as much in additional taxable income (the ratio between government tax revenue and GDP is on the order of 16%) or raise taxes accordingly, which would choke off large parts of the economy.

You are talking about a cold that could, at any time, mutate to a cold that kills ten times as many. Can we go back to normal? Sure, if by normal you mean thousands of deaths a day for probably years to come. Why not.

  9192.  @richardchapman1592  What stops you from reading the literature? ;-)

  9193.  @richardchapman1592  The wave function is not a description of the state of one system. It's the description of the averages of the quantum mechanical ensemble, i.e. of an infinite repetition of the same experiment. Quantum mechanics also doesn't describe particles. That's one of the worst scientific misnomers. Quanta are small amounts of energy, momentum, angular momentum and charge. The trivial reason why quanta behave so "strangely" is because they are not objects. They are irreversible energy transfers. Energy never behaved like an object, not even in classical mechanics. We could never assign a fixed position to energy. It was always a system property. Once you make these adjustments to your intuition about quantum mechanics all the "strangeness" goes away. The most simple classical analog are dice. A quantum would be the equivalent of an individual outcome of a dice throw, i.e. a "3" or a "5". I would not be the equivalent of the dice. The wave function represents the probability distribution of the dice, i.e. for fair dice that's just the fraction p(n) = 1/6 for every possible outcome. In quantum mechanics that's a complex function, of course and the Born rule is description of the measurement. For dice we could construct measurement operators like "The outcome is even.", "The outcome is odd." or "The outcome is a prime number.", but these are trivial for classical probabilities. We even use these "measurements" in classical games of luck like Blackjack, Roulette etc..

  9196. You can still go to the library and look up the facts. They are all there. Inconvenient you say? Well, the truth was never convenient.
    1
  9197. Among other things. C is a language that allows you to do absolutely everything that can be done on the machine. That's by design. It would be impossible to write operating systems and drivers without this feature. With that power comes a lot of responsibility. It is entirely possible to write generic C programs that do not have buffer overflows and similar problems. All one has to do is to write safe array, buffer etc. libraries that all programmers have to use by edict. There are two problems with that approach: 1) It is not trivial to guarantee the safety of such a library under all circumstance (but it can be done) and 2) It costs performance. In the past that performance problem was so severe that programmers would prefer to write their own performance optimized routines, which were, of course, not safe (omitting an expensive safety check by choice automatically leaves a security hole and it's one that hackers can probably predict even if they don't have the source code). I would argue that this is not the case any longer because most CPUs are memory IO limited and they do have the spare cycles for safety checks in most practical situations.
    1
  9198. @ It's not a rhetorical question in practice. We always have to chose between competing engineering goals. And, yes, I had C programs crash on me because I made assignments between incompatible types ON PURPOSE. Writing 32/64/128 bits on machines with wide busses is way more efficient than byte wide IO. It's also way more tricky.

  9205.  @jessoanemouszao  Science isn't trying to get a consensus, either. Science is a rational description of nature. If YOU don't like some of its results, then YOU have to challenge those results by finding new evidence. This has nothing to do with money. Where do you see bias in the question what the thermometers read???? Please be precise now, otherwise I will think that you are just a climate troll.

  9206.  @jessoanemouszao  Mathematics is a direct result of observation. The rules of standard mathematical logic are the behavior of finite collections of classical objects and their immutable properties.

  9207.  @jessoanemouszao  Dude, I am an experimental high energy physicist. I have worked on some of the largest science experiments in the world.

Sometimes we got funded, sometimes we didn't. The most expensive software license I ever bought was $25k for a layout tool. That's nothing compared to the quarter million dollar magnet that stood around in the lab or the $25 million computer that was installed in the supercomputing center. Science is expensive. So what? You can't take your money to the grave with you. What are you saving it for? ;-)

  9229. The quantum field theory landscape is, unfortunately, of similar size as the string landscape. That is widely unknown, but it is probably due to an actual correspondence. The real problem with QFT and string theory are not risky predictions. The real problem is that neither is taking any serious risks at all. They are both based on geometric representations of the Poincare group. We are still working through the mathematical consequences of Galileo's ship, which was the first modern description of relativity (at least as far as I know). This means we are still gnawing on a bone that we were thrown around 1630.

How in the world can you get away with "fewer" than two formulas when you are describing exactly one system with one and two with the other???? Can anybody around here count to two? Seriously?

  9275. We had nuclear fusion energy from the sun for over four billion years and we can make plenty of nuclear fusion in thermonuclear weapons at the push of a button. Fusion is, both fortunately and unfortunately, very viable. When you say fusion isn't viable, what you really mean is the question "Is magnetically or inertially confined plasma fusion commercially competitive with solar energy (which is gravitationally confined fusion)?". The answer is no. It is not commercially competitive now and it's hard to see how it will be competitive anytime soon. Having said that, if you are looking at other applications, like spaceflight, then it will probably be competitive with chemical and fission based propulsion by end of the century. The physical requirements are different in that application.

  9308. He pulls it out of his rear. He simply doesn't understand physics. That's all this is. Nature is perfectly local and all quantum field theory books say so, usually in the first chapter. The proper definition of non-locality automatically means a violation of relativity. Such a violation has never been observed and that's pretty much that for non-locality. It's dead on arrival. What is not so obvious is that there are non-separable states in quantum mechanics. Non-separability, however, has absolutely nothing to do with locality. It's a mathematical property of elements of Hilbert space, which is NOT the same as physical space. Hilbert space is a mathematical abstract that nature does not implement. It only exists on paper and in the mind of humans.

That won't happen, of course, but we will definitely see strengthening of the military stance of the free world in reaction to the Russia/China "friendship" in different forms in the near future. The Philippines are, for sure, already cozying up to the US again. To be honest, the Cold War wasn't the worst solution to the problem of dictatorial regimes in Asia.

Europe built massive rail networks in the 19th century and spent enormous amounts of money on flood control and maritime transport on rivers and newly built canals before that (China had already done the same a long time ago). The US built massive road networks in the 20th which still exist. Every country goes through these development steps. They are signs of normal development, not an indicator that something special is happening. Neither can China magically avoid these infrastructure measures. A billion and a half people need a certain amount of infrastructure. These are facts of life. Making value judgements about them is both cheap and misplaced.

  9344.  @Something-tx6cl  What about a joke do you not understand? And what is so hard to understand about quantum mechanics? It's the theory of quantized energy, momentum and angular momentum transfers. Guess what classical mechanics is? It's the theory of un-quantized energy, momentum and angular momentum transfers. Anybody who pays close attention in high school physics will, eventually, notice that it is not about "stuff". Classical mechanics is exclusively about the change of conserved properties of "stuff". CM has absolutely nothing to say about "stuff" itself. And if you are paying close attention to the structure of quantum mechanics, then you will notice the exact same phenomenon. Why is this? Well, because there is no "stuff". There is only a geometric and relative entity called "the physical vacuum" that is capable of exchanging these physical properties with itself. Everything else, including all "matter" and "radiation" (i.e. "stuff") is a secondary emergent effect of these exchanges. Easy.

  9346. I basically spent the first half of my life in Europe. It's not as "fun" as Americans like to think. For one thing, most of Europe is actually "zoned" pretty much the same way as an American suburb. They call it "village" over there and it's basically an upgraded medieval row of farmhouses, barns and stables. There may be one shop, which has close to nothing to sell except for bags of milk and the occasional rye bread and (rarely fresh) baloney. If you want to buy anything else, you either hop onto the bus that leaves at 9am in the morning and comes back at 3pm in the afternoon or you get into your car and you drive ten miles to the next "town", which is a village with a school and a shopping mall. Cities are better, except that now you don't have parking for your car, but at least the buses are operating on a more frequent schedule. Just don't miss the last one or you have to sleep on the park bench until the next morning. Been there, done that. Fun! ;-)

  9360. Relativity. You can't derive that from non-relativistic quantum mechanics.
    1
  9361. The trouble with statements like that is that there are no "particles" in quantum mechanics. There are only field quanta, which are irreversible energy, momentum, angular momentum and charge exchanges between different artificially defined parts of quantum fields ("systems", usually called "particle source", "particle" and "detector"). The often repeated semi-classical ontology that naive non-relativistic QM assigns to these "systems" is physically (by which I mean in an experimentally testable way) simply not realized. Even in non-relativistic QM the notion of superposition is problematic for the "casual user". Technically a superposition is reserved for an ensemble of a single quantum system, i.e. it is a property of many repetitions of the same experiment. We like to imagine that, just like in classical physics, this ensemble can be replaced by many "independent" quanta at the same time, but that is just not so. The wave function of many quanta is the product of the wave functions of single quanta, which makes for an exponentially larger phase space. This is the very idea behind quantum computing, for instance.

  9362. I have seen the difference between reflectors and refractors (disclaimer - not my own but those of people who are really into it) and, like it or not, the refractor wins and not by a small margin in my opinion as far as visual quality is concerned. Planetary photography requires large focal length, anyway, and the four or five planets that can be resolved in a small instrument (smaller than Hubble that is) are plenty bright even with small apertures. $400 buys a 4" achromatic refractor if I am not mistaken, so under ideal seeing you are trading in half of the theoretical resolution. In practice it might be a little less than that because of the better optical quality of the refractor (no central mirror occlusion). What you should really do, if you can, is to look through somebody else's telescope first to get an idea of what you can expect to see. What can be photographed at what price point can be easily assessed from the thousands of high quality astrophotographs that are on the internet now. If, on the other hand, you want deep space, then quality goes out the window and aperture is the only relevant parameter. Buy the largest mirror you can. That's just physics talking.

  9370.  @PSHomeVideo  OK, let's repeat this one more time: what any one physicist thinks or publishes on the internet is not physics. Nature tells us what physics is. In case of the delayed choice quantum eraser the sleight of hand happens in the fact that the only "non-causal effect" is seen in post-mortem correlations. It does not happen in real time. This tells you, one more time, that any and all attempts to make the wave function of a quantum mechanical ensemble an actual physical property of the system are nonsensical. But then... we already knew that.

You are basically just over-complicating an interface with them. The way she does it doesn't even protect you from anything. Somebody can enter -1 as age and there is not even a trace of a sanity check here, which is the only reason why one would use a setter, to begin with, instead of a direct assignment... to do range checks and to prevent attacks, especially through string variables than can cause overflows and memory corruption. This is not even kindergarten level.

  9391. Singularities of that kind don't exist. Not even in general relativity. A rotating, charged black hole does not have a singularity.
    1
  9392.  @SlaveRebellion-yn5wy  Yes, and that only exists in a single, unphysical solution of a non-rotating, non-charged Schwarzschild black hole. It's a mathematical artifact, even in the theory that ignores matter completely. For physically relevant black holes "the singularity" is either ring singularity or a 2 dimensional sub-manifold that seems to act like the surface of a white hole. The passage through that surface seems to take you to another universe from which you can watch what happened in "the old country", but which won't allow you to return to it. I have seen other interpretations of that metric, but the "final resting place" is NOT a singularity in any of them. This is yet another case where the public has been ignorant of the pesky details of a theory that is extremely difficult to calculate and interpret.
    1
  9393.  @SlaveRebellion-yn5wy  If gravity is a quantum phenomenon, then even talking about "the singularity" is as futile as talking about "particles" in non-relativistic quantum mechanics. These are all failed semi-classical mental models that people just can't let go off because we are still teaching 19th century nonsense at the high school level. Point is... singularities don't exist, not even in the classical case. Neither do "particles". These are all mental artifacts of poorly written Newtonian physics and classical electrodynamics textbooks. The "point anything" model kind of self-combusts even in classical physics as soon as you dare to look at it closely for more than a few seconds.

  9411. There are no problems with continuous quantities. High school calculus is a perfect example of trivial, highly useful math that "just works" as long as you keep functions well behaved.

Wells describes a parallel Earth that is supposed to be 3,000 years more advanced. People live peacefully in fairly small villages and towns. Each of these has a communal internet terminal/video phone kind of device that every inhabitant can use to communicate with other towns. When Wells wrote the novel tv had long been demonstrated and by the time he died in 1946, it was basically an established technology. He was, of course, far more interested in the social aspects of such a Utopia than in the technological ones, but it shows that technology moves much faster than human imagination.

  9429. The "law of conservation of energy" is a local law that requires time-translation invariance.

    1
  9440.  @pb0xAF09  So, please, write down the exact kind of documentation that you require for a browser. I dare you. Not for my sake. I already know that it is impossible, but for yours. I am not saying that it's impossible to write exact requirements for some code. The embedded software that I am writing right now has a couple hundred completely orthogonal functions, all of which do some very specific things in a very specific order, which is ensured by hardware interrupts. The thing is... I don't even need specifications for this code. It's a single developer project, the functionality is fluid because I am the designer of the hardware and I determine which function the software will have. If something turns out to be too hard to implement, I will simply remove it from the list of wants and the customer who buys the product will never know that such a function could even have existed. The control flow will be correct by design (it's a state machine) and all memory is allocated statically, hence I don't have to worry about little buggy things like buffer overflows. This is exactly the kind of software that one could fully specify and test. But why in the world would one? Whether a single function works or not can be tested by hand at the time of writing. That's it. Now, your web browser OTOH... that's a totally different beast. Anybody can kill that thing with a piece of crappy javascript that calculates pi to the power of e to a trillion decimal places and there is absolutely nothing that your requirements document and test suite can do about that. Javascript is a requirement and it happens to be a Turing complete language, hence you are up against the halt problem. I would suggest you take a few lessons in computer science before you make claims like the ones you made. They don't reflect well on you. :-)

  9441. There are no photons in the field. The field is the field. It contains a certain amount of energy (and even that is, technically, not true, depending on the boundary conditions, the total energy in the field is not well defined for a thermal state, for instance). A photon is simply the amount of energy that gets exchanged during an emission process into the field or that gets absorbed during an absorption process from the field. That these amounts of energy exist as individual "packets" inside the field is neither backed up by experiments nor is it part of the formulation of the theory. It's just poor mental pictures that get repeated over and over again by people who don't understand the physics and the theory of the electromagnetic field.

  9472.  @freesoftwareextremist8119  Every modern language has functions and if that is not enough for you, then you can use your language to create code for you, which is much, much, much more flexible than any form of macro for language extension. You simply don't know what you are doing. ;-)

  9473.  @freesoftwareextremist8119  Dude... macros are a very limited form of language extension. Generating code is universal. You can generate code in the same language, any other language or you can write a compiler for your own language. You can write code that writes code that writes code. All of this is about as old as the stone age. Were you born yesterday? :-)

  9475. I won't. There is a simple artistic reason for that: composition. Imagery only looks good to humans when it has certain proportions and elements of the image are placed in certain ways. That's what artists and good photographers do: they compose images so that they excite the viewer. As soon as you let the viewer change perspective, even the most carefully crafted image or movie scene looks like a boring view of a DMV office. 3d kills artistry and holography doubly so. Try buying a 3d tv... they are gone. It jus doesn't work.

  9476. @ Video games are enjoyable because they raise adrenalin and other hormone levels. That's not caused by the imagery. It's caused by the possibility of "dying" in the game. You can have the worst graphics (or even no graphics at all) and it still works. It's basically the same mechanism as gambling. It has nothing to do with 3d.

  9477. @ The most exciting game I ever played was Doom. It has absolutely lousy graphics. Still beats the crap out of most games that only run on a 16GPU supercomputing rig as far as excitement is concerned. You can get the same feeling out of asteroids and tetris. And if that is still too graphic for you, go play poker. :-)

  9478. @ It still invalidates your claim that graphics are important. One can still play asteroids, tetris and DOOM today. That's because graphics are not important. ;-) Minecraft is for people on the spectrum. The best Sim City player I have ever seen was a twelve year old autistic boy. If you are not on the spectrum, then these things won't do anything for you. I do enjoy one other old game: Gazillionaire... talk about shitty graphics. It's available on Steam, again. Nobody needs EVE Online. Gazillionaire is way more fun and won't rob you blind. ;-)

I would, however, blame you for telling your children that they have to keep fighting a battle that had been long lost by their ancestors. Your children don't have to do any of that. They have to live healthy, happy lives of their own in the reality that exists.

  9539. One can quantize gravity the ordinary way starting with a second order tensor field on a flat background just fine. It's a myth that one can't. It just doesn't lead anywhere. String theory starts at the other end and asks if one can quantize the free action on a Riemann manifold that satisfies general relativity. Lo and behold, one can. And again, it doesn't seem to lead anywhere, either. This is a strong indication that we are missing an element that is neither contained in quantum field theory nor in general relativity. We do not have any experimental evidence what that could be.

  9545. For starters, there are no particles. There are only people who don't know that quanta are small amounts of energy. Why is that important? Because if a detector can not detect e.g. a 2eV quantum, then such quanta simply "do not exist" in experiments with that particular detector. This is not a matter of retrocausality. It's already "encoded" in the setup of the experiment due to the use of such a special detector.
    1
  9546. @ Energy is a system property. It does NOT behave like particles, which are objects. All of the "weirdness" of quantum mechanics stems from the unhealthy idea that everything has to behave like an object (with position, path, size etc.) when clearly many phenomena are not objects or caused by objects. There is no such thing as non-locality in quantum mechanics, either. Most people simply do not know the difference between non-separability (a property of elements of an abstract high dimensional Hilbert space) and non-locality (a non-existent property of physical dynamics in three dimensional space). Most folks don't even notice that not even the dimensionality is the same. That, unfortunately, is a side effect of the way we teach quantum mechanics in chemistry classes, which is 100% wrong from a physics perspective, even though it is useful for the limited needs of chemists.
    1
  9547. @ There are no hidden variables. You can see this trivially in every spacetime diagram if you look at it long enough, we simply don't teach this in undergrad classes and most undergrads don't take the time to figure this out on their own. The same argument also destroys superdeterminism. I would suggest you draw yourself a spacetime diagram and you stare at it for a couple of hours. You will see it, eventually. ;-)

  9548. @ The probability distribution doesn't evolve. That's also just a total misunderstanding of quantum mechanics. ;-)
    1
  9549. @ There is no such thing as a probability distribution in nature to begin with. What we are measuring are relative frequencies. Every time we are making a measurement we are destroying the system. There is nothing open to interpretation here. The physics in the lab is 100% obvious. Draw yourself a spactime diagram. Move up the y-axis to a future point of the local observer. That's the measurement you are going to make. Draw the light cone through that point. All the physics on the backwards light cone (i.e. the past of the future point) is what determines the outcome of that measurement. What is the relationship of that subset of spacetime to the present of the local observer? It's in a spacelike separated region of spacetime, i.e. it can not causally influence the present observer, nor can the present observer influence it causally. It is completely independent of the present. In other words, what happens in the future is NOT determined by anything we can possibly know about in the present. THAT is what causes the uncertainty in quantum mechanics. It is an absolutely trivial effect that rules out any and all local hidden variables and it rules out superdeterminism.

A socialist planer has to be efficient, so they will only produce two, while competing capitalist shoe factories will make five pairs and throw two away. Even the shoes that get thrown into the trash are actual economic activity that creates jobs and GDP. So while capitalist societies keep growing, socialist economies keep contracting by default. It's not a winning recipe.

Not that neural networks are all that useful. As you can see they frell up just as often (and often worse) than the average high school dropout.

  9594.  @michaelcohen5076  The path integral is not a description of a physical process but a quantization procedure. It takes a classical action and converts it into an infinite expression of nested integrals. These integrals are not solvable except in the case of free fields (which is boring, because those mean that nothing happens, at all, except for plain wave propagation). When we try to solve these integrals numerically, we run into an enormous number of problems. They do not converge, at all, unless we sample the classical field in a very special way, for instance (using a midpoint formula, I believe). Even then this quantization procedure predicts an enormous and unphysical ground state energy, which tells us that it way overcounts something. In other words: Feynman's path integrals are not the proper physical representation of these systems. They can be made to work for many predictions, but they certainly do not express the "natural" physical state of these fields. Even if they did... "all possible paths" are no more physical than the statement that "Santa Claus visits all living rooms in the world through the chimneys in one night" is a statement about physical motion. Quanta are a phenomenon of quantum-classical system boundaries. What nature is trying to tell us with this enormous complexity is that they are not a natural phenomenon "inside" of quantum systems.

  9598. Energy is the ability of a system to perform work on another system. A galaxy receding from us can't perform work on us. In reality energy is simply not a globally conserved quantity, hence it behaves differently at the level of the universe than it does locally. It is highly likely that globally "energy" is completely "free". It does not take the universe any work to create as much of it as it like. It certainly does not seem to take any work to create more space and more time. We simply don't have the correct intuition for systems that have unlimited "resources".

The real crime is that we are basically teaching von Neumann's synthesis without explaining where it came from. The math is all correct but the student can not connect it to physics. That's not a conceptual problem, it's just shoddy teaching.

There is no metric on which Russia wins... maybe with exception of alcoholism and political stupidity.

  9618. @ I was never much in awe with string theory. I can tell you why it is necessary to go through that exercise, though, which you can't. Supersymmetry is almost inevitably necessary to explain the existence of baryonic matter. Why in the world would the universe populate stable fermionic states? Bosons are waaaaaay cheaper to make. There has to be a strong symmetry breaking mechanism that stabilizes some fermions for the lifetime of the universe and yet there has to be a way for the universe to decay again to a bosonic ground state. That's almost high school level thermodynamics. The rest of your rant is just your intellectual laziness feeling sorry for itself again. Dude, get used to it. You are not smart enough (or, if you are, then you just don't have the motivation that it takes to learn this stuff for good) and that's that. ;-)

  9627.  @geeman4399  They certainly didn't say that they felt better the second time around. They were all pretty sick for up to two weeks the way I was told. The first time around they got infected in mid 2020, so that was probably a pre-alpha variant. Now they most likely got the omicron variant. My hypothesis is that if ones immune repertoire can't deal well with one variant, then it's unlikely to do much better with another one. Like I said, they are all close family members, too (great-grandma to a less than one year old) so it's also likely that they have strong genetic correlations in their immune systems. That is another reason to be skeptical about "natural immunity". There is most likely a pool of people in every population and for every such disease that serves as a source for re-infection of the entire population.

  9636.  @CocoTheDiamond  People with normal childhood development and socialization feel shame about lying. That's the reason why lying is a sin according to the bible. It is estimated that half of all Catholic priests are atheists, but after passing through seminary they have nowhere else to go. Knowing how to lie to the congregation about theological matters is not exactly a useful item on ones resume for most jobs. So they stick to the Church career, feeling miserably most of their lives. Protestants have solved the shame problem by pretending that Jesus loves them and that they will be rewarded for lying for Jesus. That's is a very silly coping mechanism, but just like the concept of "family" works for Mafia members, the concept of being "saved" pulls them through, anyway. At the end of the day all of these are very sick psychological traits. I don't think you will have to wait very long for a holy war. Iran is close to getting the bomb, Israel has it already and Saudi Arabia just started building the facilities. Between that and the North Korean, Russian and now Chinese Imperial Cults we are looking at a really unhappy 21st century. :-)

It's just 500 pages of the same style of the same author. At most the kid will notice that even the best authors typically disintegrate after roughly two thirds of the book. The modern novel is, in my opinion, a forced literally exercise. Authors compete for who fails an impossible task most gracefully. Have them read short stories and plays, instead. The quality of writing is usually much, much higher in the best examples of those. Your obsession with reading time is also just that. An obsession with numbers. A kid who has an actual interest in literature will be able to read an entire book in a day at home and that kid will be reading dozens, if not hundreds of those over the years. To the others it simply doesn't matter.

  9694. The theory doesn't know about the structure of matter. For objects like planets and stars and even neutron stars for which equations of state exist, they can be coupled to the geometric equations and they will predict the structure of gravitating material objects correctly. In all those cases where the theory seems to predict singularities (like black holes), it usually applied without equations of state for matter. That is not exactly a failure of the theory. It's a failure in the way it is being used. The reason why it is being used this way is because there is an assumption that classical equations of states don't apply below event horizons and that the theory has to be replaced with a theory of quantum gravity. That is not necessarily a correct assumption. We shall see if precision measurements on actual black holes will uncover classical or semi-classical corrections near the observed event horizon of these objects. That will, of course, result in a different theory, just not necessarily in a quantum theory of gravity.

Let's repeat this for those people who didn't pay attention in middle school when we explained vaccines: The main reason for vaccination is to stop the disease from spreading in the first place. The primary protection of a vaccine is the fact that there is no more disease left in a 100% vaccinated population. "Natural immunity" can never achieve this. In a "naturally immune" population (which in practice means that people are constantly getting infected and dying), the disease will simply co-exist in an equilibrium with its host population.

These are all just Rube-Goldberg machines that are meant to confuse you (and their authors) about the actual physics.

  9711. The mathematical difference is the difference between p + (1-p)=1 (probability theory) and sin^2(phi)+cos^2(phi)=1 (quantum mechanics) to fulfill Kolmogorov's third axiom (which is basically a partition of unity requirement for ensembles). I am still looking for an easy to understand intuitive argument that motivates why nature seems to prefers the latter version, but I am not even completely certain that it does that. More realistic quantum models of reality like the density matrix formalism actually incorporate both forms at once, so we may be missing the real explanation because we are mostly looking at one solution or the other rather than at the most general form. At the end of the day the two formulas are most likely describing something deeply geometric but a better mathematician than I am will have to tell you what that structure is.

  9714.  @charg1nmalaz0r51  I had to learn OOP on C++... which is a real drag because of the weird syntax. I did it without any tutorials, books or courses, too. Of course I made a lot of mistakes in the beginning. What I learned about OOP on Python is that it's at most a convenience tool to avoid writing libraries (the advantage of OOP over libraries is questionable, anyway). OOP on a statically typed language like C++ gives architects the ability to greatly restrict programmers, but on dynamic languages one can pretty much override anything and everything at the instance level during runtime, so the best thought out class interfaces/APIs etc. are easy victim to the vicious programmer's creativity and there is little to nothing that the architect can do about that using OOP or any other technique. My point is that these entry level classes tell you the obvious things about a technology that you can get simply by reading the documentation, but they are rarely ever telling you the actual perspective that comes with years of use. So, no, I am not "that guy". I am the guy who keeps pointing out that what you are learning here "just ain't so" in reality.

  9728. It is exactly the other way around. Reversing time is not possible because of this. Energy always flows from the center out, reducing its density. The arrow of time is simply a direct consequence of geometry: there is always more "there" than there is "here". At least in more than one dimension there is. In one dimension there is exactly as much "there" as there is "here", so it's not clear if the 1-d folks even can afford the luxury of time.

Everybody knew the length, color, consistency and smell of your early morning bowl movement before breakfast. What in the world do you care about any of this? What is it that people can possible steal from you that is so special about you? Absolutely nothing.

  9735. The wave function isn't "provable" at all. The wave function was always a mathematical abstract. Nature doesn't know anything about it. There are systems to which it applies and then there are systems to which it doesn't. The trick is to learn about the pre-requirements for when a wave function can be used to describe nature. We rarely teach those, which makes it seem that it's a universal description. It isn't.

  9736. @ You won't find Schroedinger's cat discussed in a well organized class on quantum mechanics. At most you could make a lesson titled "Poor thinking patterns in quantum mechanics- Schroedinger's cat, Wigner's friend and the EPR paper", but it's not good practice to overwhelm beginners with historical false ideas. It's bad enough that we are teaching the Bohr model and de Broglie waves, but they are historical precursors to the real theory, so one has to mention them in the same way as one would teach Aristotelian physics or the Ptolemaic model of the solar system in passing. Schroedinger's cat, Wigner's friend and the EPR paper, however, are scientific strugglers that were muddying the otherwise crystal clear waters of von Neumann's work.

  9737. Logic is actually based on physics. It's the behavior of finite collections of objects in baskets. So, yes, as long as we are talking about objects and immutable properties of objects, logic is a very fine tool to reflect reality. It does, however, fail quite spectacularly once we are applying it to concepts that are not objects. The problem is that most humans don't know this, so they keep using logic in scenarios in which it is not the right tool. Having said that, LLMs are not using logical reasoning to begin with.

  9738. Because the visible part of the universe was much smaller, the energy density was much higher and hence it was much hotter. During the expansion new space gets created which allows the universe to cool and to coalesce.
    1
  9739.  @professormawillett4297  Because density has volume in its denominator. We teach that much in high school, don't we? :-) That there was no visible light is total nonsense. There was plenty of visible light, it just wasn't the majority of the radiation, which was at a much higher temperature. What creates space? The fact that space is empty. It doesn't take the universe any effort to create space. The cost of new space to the universe is zero. :-)

  9761.  @philippenachtergal6077  Every geodetic measurement (i.e. actual folks running around with precise measuring sticks and optical instruments) and measuring distances and angles between two points on the surface of the planet) is, at the end of the day, a proof that we are living on a nearly spherical body. The geometry of Earth is not an abstract. It's a concrete sphere and two kids with cell phones who live far enough away can reliably measure its diameter today the same way the ancient Greeks did some 2300 years ago. All they have to do is to tell each other what the angle of the sun is at their locations. I don't know why people think that differential geometry is such a big deal. Yes, it has some highly difficult to prove global theorems, but at the local level it's just sticks and stones and angles that don't add up to 180 degrees in triangles.

How old are you and what did you do with the intelligent person that used to live inside you once? ;-) It is the incorrect view and you COULD easily understand that with high school physics, IF you wanted to. But that is not what you are doing here. You are NOT applying high school science to quantum mechanics. You are using a Wikipedia quote as a reason why you didn't actually think about QM yourself. What you are basically telling me is that your main criteria for deciding which way to run is by following the crowd, even when you can see that the crowd is running towards the cliff. That is absolutely nonsensical behavior for an adult person. We tried to teach you better in school in all matters, not just science.

  9793.  @rodm8113  What you call "collapse of the wave function" doesn't exist. What happens instead is that a measurement takes all of the energy out of the system. After the measurement the system is literally gone. It doesn't have any more energy to give. You want to measure an empty battery periodically? What does that give you? Always an empty battery.

  9808. @ Quantum mechanics is not epicycles. It's a direct consequence of special relativity. You can derive it from first principles in a dozen pages of slightly above high school level math. Just because YOU don't know how doesn't mean a thing. That is a lack of YOUR knowledge and nothing else. ;-)

  9809. @ I never said that one can derive the Schroedinger equation. The SE is nonsense. It's not self-consistent and it's not physical, either. It does not conserve energy and momentum. One can derive the structure of quantum mechanics directly. That is not the same as deriving the Schroedinger equation. ;-)
    1
  9810. @ The SE doesn't work well. You can't even derive the periodic table with it because it doesn't predict fermionic wave functions correctly. It gets all the spectra beyond hydrogen wrong. Yes, you can do some systems in solid state physics with it... but that's it. Solid state physics is not fundamental. I was working in a solid state lab for years as a student. You put some dirt into liquid helium and some phonon spectrum pops out. That's all there is to it. Endless playing around with lattice vibrations. Boring like frell. ;-)
    1
  9811. @ The SE doesn't predict multi-electron atoms correctly to begin with. This has nothing to do with approximations. Atomic physics is inherently relativistic. Did you ever take a course? Have you been paying attention to what they taught you about high Z atoms and fermionic states? Are you a chemist by chance who was taught that the SE is all you will ever need? That was total bullshit.

The only physical measurements are scattering amplitudes and those are perfectly well defined in quantum field theory.

  9822. Physics is never speculative. It's descriptive. Hypotheses in physics, as in other sciences, are necessarily speculative and it really doesn't matter how far a theoretician leans out of the window. General relativity, for instance, was extremely speculative for its time. So was quantum mechanics. What matters is that the speculation turns into falsifiable prediction. That, of course, is in the hands of nature. There is nothing a theorist can do about what can and can not be tested with the financial/technological means of ones time. There are plenty of boring, more than obvious hypotheses that are untestable at the moment because nobody is willing to for a trillion dollars in funding over for the necessary size of the experiment.

    1
  9863. That is not even remotely true. You can measure a radioactive decay without influencing it. While it is correct that not all measurements are without influence on the system, that the measurement outcome always depends on the measurement is only correct for a subset of all measurements. A far better way to characterize quantum mechanics is as the unitary representation theory of the Poincare group. That gets is right every time.
    1
  9864. @ The system didn't interact. An atom or a nucleus is simply not just "an atom" or "a nucleus". It's the atom/nucleus AND the entire physical vacuum surrounding it. Non-relativistic quantum theory simply can't model that because it does not have a concept of quantum fields. One needs relativistic quantum field theory to fully understand what is actually going on here and that is why an approach without taking Poincare symmetry into account is doomed to fail.
    1
  9865. @ Lattice QCD predicts g_A (axial coupling constant) within 10% or so, if I am not mistaken, which is plenty good given the difficulty of the calculation. You are simply mistaking the ontological correctness of a theory for its numerical predictive power. Classical mechanics can only predict approx. a dozen Hamiltonian systems out of an infinity of possible ones. That doesn't make it a bad theory. It simply tells you that the world DOES NOT run on math the way you were falsely taught in high school. It's much more complicated than that.

  9866. CPU controlled machinery is being developed by engineers... people with HIGHER skill level than the workers it replaces. It only pays for itself if the process requires a lot of workers or if a sufficient number of workers is not available (like in case of food processing at the industrial scale) or if workers can't do the job to begin with (nobody can handle 200lbs paper rolls in the printing industry etc.) and the machines are reasonably cheap. Not sure what you want to do here. Replace a software engineer with a higher skilled software engineer? That doesn't exist. At least not on average.

  9883. The people who "created this problem" are homeowners in good neighborhoods. NIMBY makes it virtually impossible at the local level to increase the density of communities. This works in the short run for people who already own homes because they are rising in value faster than the reassessment of property taxes reflects. It makes it very expensive for new home buyers. The city and county governments are torn because on one hand the lack of new housing makes it harder to attract employers, but the main income source is the real estate tax, which does greatly increase when new buyers are purchasing at doubled or even tripled home prices. So, no, voting for another party at the state or national level will do absolutely nothing about the problem. You need to haver your brain checked because it's clearly not working. ;-)

So while you are technically correct that the atmosphere is above the critical temperature and pressure, it doesn't do any interesting "physical" tricks in that state.

  9926.  @Roescoe  No, it can't be. If you are moving a TByte of data onto the stack during a function call, then you are an idiot. But if you are not moving that data onto the stack, then you are not practicing functional programming. ;-)
    1
  9927.  @Roescoe  OOP simply bundles methods with data. It doesn't say anything about how different classes communicate to each other (usually by class methods that are calling objects of another class and in the worst case of the desperate programmer by calling methods of other classes on self!). Since OOP is procedural at heart, non-primitive types are usually handed over by reference, i.e. the data itself stays in place. In purely functional programming side effects are forbidden, which means that references are forbidden, i.e. we always have to duplicate the data on the stack. In practice, of course, most "functional programs" are 98% procedural because functional programming simply doesn't work in reality.

  9936.  @imkharn  Huh? QM has infinite dimensions. That's exactly what upsets most people. It can't be reduced to a finite number of degrees of freedom. Yes, configuration space is parametrized with energy, momentum, angular momentum and charges (and if you want position), but the actual quantum mechanical "phase" space in which the ensemble, not the single quantum(!), moves is either a function or, worse, an operator over configuration space. That's a mighty big structure. In quantum field theory it gets even bigger because all combinations of fields (even those forbidden by conservation laws) appear inside the calculations as "virtual particles". It's an utter mess.

  9945. We teach it in undergrad physics, more specifically thermodynamics and statistical mechanics. It's such a big deal that we usually devote a whopping ten to fifteen minutes to the topic. It also follows trivially from the requirements that a measurement should leave a lasting record (requiring an irreversible process) and from the third law of thermodynamics. If you don't understand this (and Tim Maudlin does not), then you have no business in physics.

    1
  9965. There are very few use cases in my experience. GUIs are probably the prime one and the only one I have encountered in practice. The reason for that is simple: very few problems factor into the kinds of dependency trees that inheritance models. Most problems have a dependency graph (non-cyclical, of course). That can be implemented much easier and without drama with other approaches.
    1
  9966.  @sgs1402  No, of course not... but for that to work you have to be able to foresee all your dependencies across the entire future history of your software development. Since you are a software god, that works just fine for you. We mere mortals don't have that vision of the far future and are better off avoiding the self-bondage that comes with inheritance. ;-) Look, I have used OOP on GUIs a couple of times and it worked just fine. GUIs don't perform any significant functions, though. They are window dressing. In most real world problems that have to deal with actual data, dependencies keep propping up that usually reach from the level of single data elements all the way to the state control of the overall system. If you try to solve that with inheritance, then basically everything has to inherit from the most sensitive (state) part of your system. That is really poor software design. It is far better to leave such sensitive pathways to a well defined set of independent methods that are completely isolated from both the data and the state.

  9967.  @sgs1402 Architects who are in love with OOP do. Other than that... nobody. It's not an appropriate approach. That was the point.

  9970.  @hannes7695  No offense, but you sound like a hard physical realist. You seem to believe that a quantum state is an actual physical property in the sense of a classical state. So if two of these properties are correlated by a global symmetry, they have to be causally linked. If the ball is turned around here, then the entangled ball at the other end of the universe has to turn as well. That is exactly what nature tells us does not happen. I hope I misunderstand your comment.

  10003.  @wmstuckey  OUTCOME, not as an actual realist physical state. Realism simply doesn't work in quantum mechanics. How many times do we have to repeat that before it sinks in? We knew this since 1927, latest. That's almost 100 years of people NOT listening to the physical facts.
    1
  10004.  @wmstuckey  OUTCOME. A state is always an outcome of a measurement. That's no different from dice. You roll dice by giving them kinetic energy. At that point they don't have a state that can be expressed in terms of outcome states. The shed that kinetic energy by friction with the table. Now they have an outcome state... until you roll them again. Same thing is happening here. The outcome of a quantum measurement is the quantum of energy that the measurement device removes irreversibly from the quantum system. Without that removal process the value of that quantum is simply not defined. That's physics from 1927.
    1
  10005.  @wmstuckey  How would I know that there is a quantum if I don't detect it? Do you believe in ghosts? In that case I will claim that the physical vacuum is full of ghost quanta that nobody can detect. How are you going to prove me wrong? That's not science. That's how religion works.

  10010.  @JonathanJollimore-w9v  Science is the rational description of nature. If nature doesn't show us something, then science is not required to describe what it doesn't show us. This isn't religion. We do not care about things that are only in people's imagination. IF there should be discrepancies between gravitational wave signatures of merging black holes and measurements by LIGO, then we will have to modify the theory. I am not aware that such discrepancies have been found, yet. For all purposes of science a black hole is simply an event horizon and we have a full theory for that.

What we can see of the visible universe today may have "begun" (in the sense of our modern clocks) in a volume that was much smaller, maybe the size of an orange. The problem with such "comparisons" is that they convey absolute scales that the universe most likely doesn't care about. Try to imagine the universe as a fractal. Not only is there no "bottom", there is no scale at all. You can zoom in as much as you like and you can zoom out as much as you like... it always looks the same if you are looking at a large enough volume with large enough resolution. The problem is that "large enough" in case of the universe may imply hundred orders of magnitude (or hundreds, potentially even thousands). That's just too much for the human visual system to handle. Maybe we can make a logarithmic plot of sorts that shows this properly. And ultimately... if there is no scale, then there is probably not even a range of scales for the repetitions of patterns, i.e. there are always patches that are arbitrarily large before a pattern repeats. That's like a hyper-fractal. I can't visualize that. ;-)

  10018.  @Danny_6Handford  "Many famous and main stream scientist think..." Stop right there. What scientists THINK is NOT science. Science is the rational description of nature. All I ever remember seeing in the primary (papers) and secondary literature (textbooks) are formulas and plots for the density of the universe. That's what the theory predicts. It does not predict size. Can you show me a paper that contains a size prediction or, even better, a size measurement? "...that the size of the universe before it started to expand..." Nobody has ever seen a non-expanding universe. I don't know where you are taking that idea from? Diagrams that stop at some arbitrary time scale? That's a choice by whoever made the diagram, it's not an actual measurement of an initially static universe. There are suggestions out there that the universe is inflating eternally, but those are extrapolations. There is no data and there is not even math to arrive at that conclusion. What the universe does on unobservable scales is unknown and will potentially stay unknown forever. "The math appears to support this idea..." Science is not math. Math is just a description of what we observe. We can extrapolate beyond what we have seen and sometimes that extrapolation is correct. Often it is not. You might as well be throwing dice for all your cosmological needs if you go "by the math". Nobody in physics works that way. We know at all times what has been observed and what is pure extrapolation. In this case everything before the electroweak unification scale is complete extrapolation. That doesn't get you anywhere close to "the universe was the size of an atom". "We now know that our universe produces billions of black holes and I am probably not the only one that thinks black holes are the “seeds” for the creation of a new universe but only a tiny percentage of them will create a new universe." OK, that's just poetry in motion now. There is not even math to support the idea that what's inside a black hole is a new universe. The math that we have predicts an extremely hot and violent environment that cooks all information about the past out of what fell in. What we "believe" based on the extrapolation of "the math" is that what comes out of a black hole is mostly featureless black body radiation. Only a tiny percentage of the infalling baryonic matter can re-emerge as baryonic matter. Maybe not even that.

  10023. And that's fine. Science is a story. It's a very particular kind of story which tries to get as many details right as possible, but it is still a story. The problem with stories is that they have to be evaluated for their truth content and most people are either too busy or not intelligent enough to do that bit. They take stories the like at face value, which invites some storytellers to abandon the truth in their stories and to make them all about self-promotion and ultimately economic gain. Sabine is one of those who fell for that kind of storytelling.

  10047. It's called the universe. It would have been better if physicists had not adopted the multiverse terminology but instead had called it something like a "multi-domain universe". That is both mathematically and scientifically far more accurate. Personally I like the term "foliation" but it happens to be used already for a very different kind of phenomenon. At the end of the day, though, what's in a name? A rose by any other name smells just as sweet.

  10048. Einstein is, on some scale, definitely wrong. We know that simply from theoretical considerations. Unfortunately that scale is completely inaccessible with current experimental techniques. Gravity may, indeed, not be quantized. The difficulties of developing self-consistent "conventional" quantum field theories of gravity are certainly telling us something important, we just don't know what. If gravity is an intermediary effective force, then it would behave mostly thermodynamically, possibly with some remnant quantum correlations. The problem is that such an intermediate "effective" gravity could actually make the detection of the actually underlying quantum theory (or post-quantum theory) even harder. It's like trying to do x-ray crystallography at the bottom of the ocean... not a very good outcome for physics.

  10073. That's true everywhere. A lot more people have covid than are getting tested. Not only that, but most people seem to be vectors for about five days, so if you multiply the the number of positive tests with two for undercounting and five for the length of the infectious phase (i.e. 10 overall), then you get an estimate for the number of people in the population who are active vectors. That was easily in the 1-10% range for many regions in the US. In other words... you were pretty much guaranteed to be exposed every time you went shopping. Thankfully even the latest variant is not infectious enough to make short exposures at a reasonable distance a real risk. At least it doesn't look like it, yet.

  10095. Humans don't have to think that way. Only the software architect has to think that way. The individual programmer does not have to and should not be required to look beyond the objects under his care. What they do in a greater context is not his responsibility and keeping him away from the top level design allows him to focus all of his attention on the quality of his code. A single programmer can easily deal with a fat interface of hundreds of functions in his own code. What he can't deal with is the ten thousand other functions in hundreds of other interfaces. Things start going downhill whenever the architect fails to shield individual designers from the complexity of the entire design.

  10131. If you are listening to her you will never understand. She is simply talking nonsense here. It is theoretically extremely well understood what a measurement is. It is, BY DEFINITION, an irreversible energy transfer. The only problem here are theorists who are stuck at the kindergarten level of theory in which everything is reversible all the time. You can find such theorists in classical mechanics (they are only doing Hamiltonian mechanics on systems with finite phase space volumes) and in quantum mechanics (these are the ones who are talking about the "measurement problem"). Relativity provides a trivial solution to all of this and this was known since, at least, 1932.

  10132.  @galegreyson4196  I was an experimental high energy physicist. I have done trillions of quantum measurements while I was active. Not once was there a problem, either in the lab or in the theory. The theory even spells out explicitly for us what needs to happen to have a measurement outcome. It is very strange how many theorists seem to be completely blind to that element. That is the real mystery here... why otherwise reasonably smart people have such deep misconceptions about a nearly trivial topic. They can handle much more complicated stuff with ease, but when it comes to seeing the obvious they are blanking. ;-)

You will get the time to learn algorithms and data structures, machine design and lots of other stuff that a software engineer needs to know. Most importantly it's four years during which you are allowed to make mistakes without a career penalty. Once you are on the job your boss won't even give you four weeks for those.

  10140. Quantum computing has been "a thing" since the beginning of the universe. Every single proton, for instance, computes the proton mass, something we can't do with classical computing very well. Every hydrogen atom computes the entire spectrum of hydrogen to infinite precision. That's very cool. It's also very useless. The problem is to make useful quantum computers and that is still lacking. There are fundamental reasons why it may not amount to as much as the current hype predicts.
    1
  10141.  @adampullen3786  A proton is a quantum system and it does produce a measurable physical property called "mass" that is very hard to calculate classically from first principles. To somebody in the field of computing that's a calculation and it's a valid "benchmark" between classical and quantum systems, whether you like it or not. So is classical chaos, of course, which not even a quantum computer can calculate. That we both agree that nature doesn't actually calculate doesn't matter. That's just idle philosophy at the practical level.
    1
  10142.  @adampullen3786  One can easily build room temperature quantum computers from photonics elements, they are just hard to reconfigure. It's really the programmability or better configurability aspect that makes quantum computing hard at the moment. That's also one of the fundamental limitation in my opinion. Yes, a QC with 100 qbits is theoretically much faster than any current classical computer... but its "program space" is limited to a few hundred bits that are describing the interconnections of the machine. There aren't that many short classical programs that are useful. Why should there be many short QC programs?
    1
  10143.  @adampullen3786  Exactly, a practical quantum computer has to be able to solve many different problems. What I am saying is that we do have proof that quantum mechanics can compute SOME hard to compute functions. What we don't have is a machine that uses quantum mechanics to compute MANY USEFUL hard to compute functions. If anything, I would be skeptical about the feasibility of the latter. That quantum computers will do wonders for theoretical physics is more or less obvious. But then... how many users does that make? Not all that many.

  10144. They have been offering alternatives... with the same result.

  10157. Humans live traditionally in relatively small tribes. Typical anthropological estimates are on the order of 150. The natural environment does often not support larger groups. We don't have to guess this. We can derive it from caloric needs and the fertility of uncultured (and even primitively cultured) land. Since the mortality is very high, many of these individuals are children and teenagers. A few are elders. The total number of men and women of reproductive age is small, maybe on the order of 50. This is very close to the genetic limit set by diseases caused by in-breeding. In other words, a healthy tribal population either has to regularly exchange members with other tribes or it has to practice a fairly open sexual morality that creates as much genetic variety from that gene pool as possible. These are just biological facts. There is no need to attach emotional values to them.

  10163. Did you pull that turd out of your own rear or somebody else's? There is not a single condo or single family home within five miles of my place that is owned by a corporation as far as I am aware. My rental building is owned by an elderly lady who will probably hand it down to her family.

  10164.  @AKATenn  I am living in a smaller city (nothing of the sort of New York or Chicago or LA) and there is no large scale development going on here even though there is employment. That there isn't is the problem. There are simply not enough one and two bedroom units for the younger people who want to live here. That's a consequence of NIMBY. People aren't losing a lot of homes right now. There is hardly anything on offer because everybody who owns a home is holding off on sales if they can. They are waiting for higher prices.
    1
  10165.  @AKATenn  That "it's more worth it to keep it empty" is absolute nonsense. That developer is losing an enormous amount of money right now. What happened in your neighborhood is that they overbuilt or they misjudged the demand for that particular price range and kind of real estate. In no universe are empty buildings worth more than buildings that are producing hundreds of thousands of dollars of rental income every month. I have no idea where people are getting these strange ideas from. That people are waiting for prices to go up is not a "problem". Do you want to force people to sell at a fixed price? Are you a communist or something? What kind of bullshit idea is that? There is a market and the market allows people to make choices. They can buy and they can sell or they can decide not to do either. End of story. Now, the are better regulated real estate markets in the world. See e.g. Singapore. Care to guess what is going on there, right now? Home prices are exploding, despite all those regulations. Regulations can't beat supply and demand.

  10166.  @AKATenn  Homeless are not in the market for million dollar homes. Not every problem is the same problem. That's what I am saying... you are suffering from NIMBY. Are you by any chance living in "gentrification Karen land" aka San Francisco? That's another one of those diseases of the mind... this idea that everything has to stay as run down as it was in the 1960s and 1970s. Yes, some people do get pushed out of gentrifying markets. Those are the people that have kept the place in squalor for decades because they didn't have the income to make it better. They can live in squalor somewhere else. Nobody of importance cares.
    1
  10167.  @AKATenn  Like I said, nobody around here sits on 10,000 empty properties. Even if they did, it wouldn't do anything for the homeless. Just give it some time. A developer can only afford to leave a property empty for so long. After a few years they will start lowering prices.
    1
  10168. Yes. There are no detectors like that. A normal photodetector is always absorbing. The easiest way to build something like that is a magnetically powered level arm with the photodetector on it. When the power supply of the bomb is on, then the photodetector is in the light path, when the power is off, then it drops down or is pulled to the side by a spring. But then, what did you really build here? A slightly more complicated double slit experiment with a mechanical shutter in front of one slit. Detectors a and b would simply sit in the central maximum and the first minimum. That's it. There is no magic here, just a silly but ultimately trivial variation of a known system.

  10172. Time is that which the clocks show. Since one can't accelerate a clock to the speed of light (because it is massive), the entire question is nonsensical. That light can "measure" spacetime just fine without a time measurement should be obvious. That is what the GPS system does by combining four or more distance measurements. If you want the precise mathematical explanation, you can find it in Misner, Thorne, Wheeler "Gravitation". It's a very good introductory textbook that discusses general relativity from a geometric perspective.

  10175.  @Jay-nq2jl  Wise up how? Neither Mexico nor Canada are dumping products into the US. Many products from Mexico are actually made there by American companies for the US market. They will simply pay the tariffs and then hand them down to the US consumer.

NATO has over 3000... and they can attack Russia from the West, the North and the East. Russian air defense would be very busy... for a day. Then there would be no more Russian air defense. After that there would be no more Russian fleet and then NATO would dismantle all of Russian logistics and transportation hubs. The entire country would run out of gasoline and diesel within a week, tops. How do you think Russians would think about the war if the stores were empty? ;-)

  10184. Not much. The problem will probably be just as hard on a quantum computer as on a classical one, if not harder. The great myth about quantum computing is that it can speed up all calculations. That's principally false. QC can perform better on some problems, but it can not perform better on all problems and the reverse is also true: there are some problems for which classical computation is actually more powerful. The universe uses both methods.

I would suggest you take a really good look at the level of destruction that this war has been unleashing on Russia. They now have over 600,000 killed and wounded, lost a sizable portion of their cold war weapons arsenal and the bleeding won't stop. By mid next year Russia will be well into a million casualties and it will have lost most of its weapons. That is the strategy behind the US and NATO actions. Drag this out and make Russia pay an impossible price. We the people are not guilty by anything. Neither is Biden. The only guilty parties here are Vladimir Putin and his henchmen.

  10216. On an embedded system you have to be able to randomly access hardware registers. That's far easier than you think, but you just have to LEARN that skill. You can not expect library developers to take care of everything for you that requires actual LEARNING. And even if you could, you shouldn't because eventually you will be a better coder than those library developers. Most libraries for embedded systems are written by disinterested semiconductor company employees. They are underperforming and buggy. Not to mention that most embedded hardware is buggy and you have to find workarounds for YOUR application.

  10231. ​ @paradiselost9946 Not where I live. There are some businesses going out of business that should have never existed, like Bed, Bath and Beyond, which is really just another Toys'R Us niche model that is being made obsolete by online retail reality. If you are talking about "footpaths" as "local recreational activities", my city has just opened a new walkway in one of the parks. It's quite pretty. Homelessness in the US is not well documented. Modern data seems to be only available since the early 2000s and homelessness has been holding steady at roughly 600,000 or 0.2% of the population. We can infer from the catastrophic situation during the Great Depression that it was much, much worse back then. Estimates range in the millions (we know that 12.8 million people were unemployed in 1933), which made homelessness a ten times worse problem than it is today. Most of the current homeless are not primarily homeless. They are people who simply can't care for themselves but aren't seeking (and are not forced into) government care. Providing shelter doesn't solve their actual problems. Most of these people would need actual mental healthcare services. We don't have laws that would allow us to force the psychotic (but harmless) into care facilities.

  10241.  @cedricdellafaille1361  I don't know what you mean by "bad companies". What "bad companies" is the German government propping up? Intel isn't "a bad company". It is one of the essential suppliers of CPUs for the global economy. If it went bankrupt today everybody would suffer. The US government is investing in domestic chip manufacturing because a Taiwan war will destroy the world's leading chip manufacturing capacity. It wouldn't just "change management". Those Taiwanese factories will be physically destroyed. We have to have a replacement for that manufacturing capacity. Single source is not a rational choice. It's a risk. Europe's economy can't grow because there is simply not enough circulating money around. No amount of business activity can make up for poor macroeconomics policies of the EU.

  10282. @ Photons don't have a path. Photons are small amounts of energy. Energy never had a path, not even in classical physics. It's a system property that gets exchanged between physical systems. That photons are said to have a path is simply the side effect of the unfortunate fact that nobody is paying any attention in science class when the concept of energy is being discussed and then they are not paying any attention, again, when we explain the Copenhagen interpretation. Light is neither a wave nor a particle. Light is the excitation of a quantum field. Wave-particle duality is simply a false dichotomy fallacy. Dirac pointed this out in the 1930s, but, again, nobody was paying any attention in science class, even back then. That still hasn't changed. ;-) If you want to understand what is going in here then you will have to learn to let go of "particles" and "waves" and you have to replace these concepts from classical physics with working concepts in modern physics like "boundary value problem" and "Lie group symmetries".

It's an exponentially shrinking god. Pitiful, really. In Genesis he can drown an entire planet in an ocean, by the time of the NT he can only convert a few gallons of water into wine. That's a 20 orders of magnitude reduction in water volume. The latter trick is, of course, well within the capabilities of professional magicians, even at the time of Jesus. Every better potter can make double walled vessels for you. :-)

  10315.  @ckay_real2765  That's not Genesis. That's a poor English translation of a poor Latin translation of a poor Greek translation. Genesis is written in Hebrew and it doesn't say that. You should read the original when you can find the time.

  10317.  @rizk131  Electrons are quanta (small amounts) of energy, momentum, angular momentum and charge. The particle nomenclature is one of the most unfortunate and most misleading language choices in all of science. You will, for the better or worse, have to learn to ignore it. Simply translate "particle" to "quantum" every time you hear or read the word in your mind and then filter out all the talk about "particle properties" that quanta simply can't have. I don't believe that this was done "deliberately". The folks who discovered quantum mechanics in the early 20th century simply came out of the materialist mindset of the 19th century. They were brought up with false mental models of nature. It is very hard for a human being to let go of false mental models. We are, of course, a hundred years later now and it is a shame that even the latest textbooks aren't correcting these sins of the past. So, yes, you are correct. Quantum mechanics is very hard to learn because the student is constantly being made to use language that is not appropriate. I don't have an easy solution for you. What I can tell you is that if you learn to look at quanta as small amounts of energy and at quantum mechanics as an ensemble theory, you will soon enough understand that what you are looking at is nothing more and nothing less than a solution to Kolmogorov's axioms that is compatible with special relativity. Kolmogorov's axioms OTOH are really nothing other than a partition of unity.

  10324. The reality of quantum mechanics is exactly the same as that of general relativity. In QM classical observables are only valid at infinity where the interactions between final states go asymptotically to zero. In GR they are only valid at infinity where spacetime is asymptotically flat. Both theories make exactly the same assumption about the large scale structure of the universe. So, no, that is not the problem, either.

  10337. There is no disagreement. Nobody can tell you how to calculate this quantity correctly. It doesn't drop out of quantum field theory in a natural way. Why does it no do that? Because quantum field theory is an ensemble theory with an infinite number of ensemble members. Therefor the theory can not make a statement about the total energy density of a single member of the theory. There are ad-hoc calculations that have no theoretical motivation that are wrong by many orders of magnitude. So what? So nothing. ;-)

There has also been no reluctance to help Ukraine. The US has been giving Ukraine vital intelligence long before the war even began. Without that intelligence Ukraine would have been overrun for sure. Moreover, it is highly likely that the US has been sabotaging the military space resources of Russia for a very long time. That Russia is virtually blind on the battlefield is the result of decades of active US defense posture.

  10344. Particles don't exist. This term is probably one of the worst misnomers in the history of science. What we are actually dealing with in quantum mechanics are quanta (small amounts) of energy, momentum, angular momentum and charge. These are locally conserved physical system properties that can be transferred from one system to another. Quanta are not waves, either. If we detect many quanta and we are plotting their frequencies against location and time, then we can sometimes discover wavelike patterns in the data. Not always, but under the right circumstances. There is nothing impossible to understand here. All of this is actually completely trivial, most people just don't know what they are talking about but keep talking bullshit anyway. ;-)

  10352. The problem is not that it's shameful. The problem is that it doesn't even exist. These are NOT deposits that are ready to mine. These are suspected deposits that may or may not lend themselves to economical mining. Even if they do, then the total revenue will, at most, be in the range of a couple billion dollars a year, which even at 25% profitability (unheard of for most mining operations) will result in, at most, a return of less than a billion dollars a year... on investments in mining infrastructure that could total tens of billions. This will barely return the interest on the upfront mine investment, let along anything resembling a return on the military aid that was provided by the US. Trump is, again, just pretending to be a business man. No real business man would even contemplate a deal like that after doing the numbers on the back of a pack of cigarettes.

  10355. There is nothing to follow there. There is no such thing as "measurement independence". The results in quantum mechanics are highly dependent on the measurement. One can, at most, formulate it relativistically by saying that initial and final states in QFT can not be correlated by the two endpoints because from the viewpoint of any one local observer the two events are spacelike separated. :-)
    1
  10356.  @animalbird9436  Yes, quanta are "just energy", or to be a bit more precise, they are combinations of energy, momentum, angular momentum and charges. And you would be absolutely correct to say that this process is classically forbidden. It does not exist for classical electromagnetic waves. We can "upconvert", e.g. with frequency doubling or tripling and we can mix two waves of frequencies f_1 and f_2 into f_1 + f_2 and f_1 - f_2. We can classically not produce f/2 with optical materials (even though we can with non-linear electronic circuits that are externally powered) for all I know. Quantum mechanics does not have that restriction and there are non-linear crystals where the crystal can absorb just the right amount of angular momentum to produce a two-quantum state with quanta of half the energy and a total spin of zero, even though the incoming quantum had a spin of 1. Surprising but both experimentally and theoretically fully understood.

There it's not the total number of women that is the problem but the rigid social structures that prevent people from forming successful partnerships.

At some point we will have to remove people who test positive with covid from regular hospitals and send them to special covid death wards.

That's more than enough time to buy a farm or at least a nice single family home in a safe, clean, healthy place. That's also the much better real estate value than Gaza.

The same AI can be deployed a trillion times, learn a trillion facts and have a trillion experiences and then be merged back into one... which then can be deployed again and again. Death to humans is only painful because we can not be forked and backed up. We can't pass on our experiences directly. If anything AI will have to learn to selectively forget to stay sane. It won't suffer from a fear of death, it will at most suffer from an overabundance of bullshit that's surrounding it.

  10442. A rational reason for many users to buy Apple products was productivity. I have been in mixed PC/Apple Mac environments and have seen cheap PCs fail, while the Macs would soldier on for many years without a hitch. Where time is money that's actually a very valid concern and buying a slightly more expensive Apple design will, over the long run, very often returns its money. Now, mind you, this is a statement about older iMacs, I have heard that MacBook users are not always having such a positive experience lately, so one has to decide on a case by case basis. I consider phones as throw-away hardware anyway. They age out and that's how one should treat them after three or four years.

The hard part, of course, is to not keep holding onto such a large piece of baggage for the rest of your life. That's not "her" fault, though. That's you holding onto the past. It's a human trait to do that. It also doesn't work. You have to learn that it doesn't work and then you have to let go.

  10463.  @PabloRocha-yv2vz  String theory is not even theoretical high energy physics. It can not make any predictions about the spectrum of the vacuum. Theoretical physics is the mathematical description of measured physical phenomena. String theory makes currently no contact with any measured phenomenon.
    1
  10464.  @PabloRocha-yv2vz  A hypothesis has to be testable. String theory is not testable right now, hence it doesn't even rise to the level of a hypothesis. Physicists call these things "not even wrong".

  10467. The problem with this description is that there are no particles in quantum mechanics. There are only quanta and quanta are not objects. They are irreversible energy transfers from a quantum field to an external system that we usually call "detector". It is not the quantum field that takes on the classical state of spin up or spin down but the detector. The sock example simply shows that one can trivially reproduce entanglement with a fully classical system just as well. There is nothing strange about that part. What is "strange" in some sense is that the quantum version of entanglement with spins produces different probabilities than the classical version.... but then, it does that independently of distance, which tells us that distance has absolutely nothing to do with anything.

  10471.  @davidbutler9323  You asked what string theory is. String theory is a trivial extension of quantum field theory. Trivial in the sense of how it's defined, certainly not trivial in the consequences of that definition. Whatever it may seem to you, to a physicist who has spent a few minutes thinking about it it's an utterly necessary mathematical puzzle. If we can't solve this toy puzzle, then we can't hope to solve the actual puzzle, either.

  10472.  @davidbutler9323  Why would I watch nonsensical videos? The guy doesn't know anything about string theory, either.

They are all out in the open where the Ukrainian drones and artillery can get them.

  10496. Did you notice that they are discussing a strawman? There is no multiverse in physics. You will not find it in any serious textbook or paper. You may find statements like that string theory has around 10^500 possible alternatives. That, incidentally, is not all that many more or less than what you can get out of the standard model if you insert reasonable assumptions about the possible internal symmetry groups. Relativity (which is responsible for both) simply does not select this universe a priori. It selected this universe dynamically. Our theorists can not do the necessary calculations, yet, to determine what such a dynamical selection process does and does not lead to. A hundred years from now we will know the necessary math and that's that. :-)

That's because you are formulating a very strong hypothesis which simply isn't true. :-) I don't see any statistical evidence for long term protection, either. Does infection protect you for half a year? Sure it does. It always did that for the flu, too. The problem is that once that half year is up, the virus has mutated and your antibody count is back in the woods. End of effective protection.

You have to keep in mind that there are only two or three steps between a NATO enforced no-fly-zone and nuclear war. One should not escalate to that level easily. Ukraine is doing just fine eliminating the Russian army right now, by the way. It comes at a very high human cost, but it is happening nevertheless.

Would I call that "popular"? Given that the Roman Empire had maybe four million inhabitants, no, not really.

  10606. We don't have a measurement problem in either case. All measurements are simply irreversible energy transfers. We are teaching this in undergrad thermodynamics and statistical mechanics but some of the theorists aren't paying any attention because they don't think that they need to understand this rather trivial fact. And for the most part they are correct. They don't... except when it comes to the interpretation of quantum mechanics, for which it is fundamental.

  10616. Yes, that's just total bullshit. 99% of what I write is either for the console or it has no terminal IO for the user, at all. There are simply different applications for software. What most people are used to are GUI apps with buttons and dials and fancy text fields and custom controls. Games fall into that category, too, except that they have to produce real time responses in addition. And then there is a totally different use of software, which is servers, databases (backends in general) and industrial software tools, many of which are connected to a hard button interface. He is simply not talking about that because his audience (absolute beginners in the field) will not be doing that to begin with (you ain't going to write microcontroller code for hardware that you didn't develop yourself, for instance). Be that as it may, the console is one of the best side channels, even for the GUI developer. It allows you to do quick and dirty things that can simply not be done with GUIs. Learn to use it well.

  10617. The PR team is comprised of English majors. They are usually not even business people and they always write what the CEO tells them to write.

It may be the problem of your boss's boss and it may percolate down to you, but to get upset about it is pointless. Your don't have a handle to crank to make it go away. I did a science project at a government lab once. The rule was the the scientists working on some sub-project would say x hours and y million dollars. Then the local project manager of that sub-project would double that estimate and send it to the top level project manager. That project manager would double that estimate, again, and then the funding agency would say "We are giving you the money but expect that you deliver 80% of what you promised in 120% of the time.". Then everybody would work seven days a week to barely make that relaxed timeline. If you think that you can predict the future, then you aren't experienced enough, yet, to be allowed to make predictions.

  10621. Why would it? What you call collapse is actually the removal of energy from the system. This can only happen through gravitational waves and they are way too weak to remove even one quantum of energy from any of these systems.
    1
  10622.  @pawelczubinski6413 Only if you remove energy from the system and gravitational waves can't do that.
    1
  10623.  @pawelczubinski6413  That's not the physics behind all of this. That's the solution theory of the Schroedinger equation as presented to you by von Neumann, a mathematician who at the time was deeply involved with functional analysis. A quantum measurement, as in ONE detection of a quantum of energy, is the exchange of one quantum of energy between the quantum system and an external system that we usually call the "measurement system". What "collapse" means is simply that the quantum system before the measurement had either less energy or more energy than after the measurement. If it has the same amount of energy, then a measurement did simply not take place and the ensemble of the system can be described by the unitary evolution of the ensemble's wave function. If you read Heisenberg's papers on matrix mechanics (1925, I believe), then you will find that the energy differences between "before the measurement" and "after the measurement" (that's the amount of energy which we call "the quantum") are still part of the theoretical description. By 1932 when von Neuman writes his abstract mathematical treatise on the math of the Copenhagen interpretation, that immediate connection between the actual physics of quantized energy transfer and the "state" based theory of the quantum mechanical ensemble had been severed sufficiently so that future generations who are learning von Neumann's math were and are having a hard time to actually derive from it what happens at the level of the physical system. That's an artifact of the way we teach introductory quantum mechanics. We tell you the math but we don't tell you what it actually means. In this case, of course, you have to understand the actual physics of the process, the mathematical structure of the theory tells you absolutely nothing about what is going on.

  10644. The derivation of general relativity will be the same in 2071 as in 2021. That the cosmological constant can be made part of the equation is trivial. So can other, higher order terms that are just not included in most books about the topic (except in tiny chapters about modifications and extensions to GR like Brans-Dicke and GR with torsion). That the cosmological constants is not some external energy term is simply the standard interpretation of the theory. Is GR wrong? Of course it is. That's a trivial thing to say, though. Unless YOU know HOW it is wrong, YOU don't know anything more than anybody else.

  10647. Mixing two or more bad paradigms doesn't lead to better software design. It just shows that the architect/programmer doesn't like to think. Many are happy to apply pre-canned solutions in a reflex-like manner in their work and paradigms fit that unhealthy engineering style. Is that how a real engineer should think? No. A real engineer should start with the problem and deliver a solution that is correct, on time and on budget, no matter how that is being done.

  10648.  @anasouardini  Take "statelessness" as a paradigm. That's outright delusional from the start. Why? Because most software is actually tooling to change the state of (somewhat) persistent storage. Uploading a video changes the state of the server drives. Sending email changes state because we want persistent records of past emails on our devices. Playing a computer game is the constant change of state of the representation of the player's avatars etc... How can one achieve change of state with a theological belief that the code should not create state/change? The engineering problem with state is not that it should be avoided, rather we have to make sure that all state change is well defined and that these changes can only happen in guaranteed atomic units to preserve the integrity of the state. The correct definition and handling of a program's state is an architectural problem. By the time we hit the code level it's already too late to try to fix bad architecture with language syntax. One can say similar things about other aspects of OOP/FP, but in general they mostly seem to come down to the belief that hard problems (and, yes, system design is a very hard problem) can be simplified automagically at the language/code level. Even a cursory book into an entry level computer science textbook will invalidate that belief easily.

I have designed parts of machines that have made trillions of quantum measurements. Not once was there a problem with the question what we were measuring and how it was done or why these measurements are possible in the first place. That is all kindergarten level knowledge to a physicist. If the world seems complicated to you, then not because it is but because you weren't paying enough attention in K-12 where we tried to teach you how to stand on the shoulders of giants. It's your own fault that you can't see the world any other way than from carpet level. ;-)

All you are proving is that a computer scientists knows shit about physics. It's really simple, children: If you want to learn the piano, then you have to practice the piano. If you want to learn computer science, then you have to learn computer science. And if you want to be a physicist, then you have to learn physics. OK, Sensei? Are we cool? ;-)
    1
  10672. @ The complete argument? Measurement is required to leave a lasting record, which means that it has to be an irreversible process. Things can not go back to where they were after the measurement. It has to be an energy transfer because the measurement system (like every other system) has to have an effective temperature T>0 according to the third law of thermodynamics. The only way to make the measurement result distinguishable from thermal noise is by transferring an amount of energy E that is greater than kT. This is such a "deep" insight that a typical second year thermodynamics/statistical physics course will devote a total of 10 to 15 minutes to the topic and maybe another half hour of student exercises, if we are generous. In other words, it's about as "complicated" as the difference between data and a pointer to data in CS. It's also equally fundamental. If you come out of undergrad physics without having understood this triviality, then you will struggle with a lot of foundational stuff in quantum mechanics, not to mention experimental physics.

  10703.  @daniellarson3068  Anger tends to cloud the mind as well. Why don't you read up on the legal framework in the US. A US citizen/company CAN NOT support a foreign country with these kinds of activities without the explicit OK of the US administration. That would automatically trigger a visit by the FBI and it wouldn't end there but in jail. I used to work for a company that made fairly trivial dual use technology. They were joking about what they would do if they ever got an order for e.g. 500 pieces of that product from Lagos... and the answer was to inform the FBI and to tear up the purchase order. Yes, it really is that simple. If SpaceX didn't support Ukraine, then the order for that came from Washington and nowhere else. ;-)

  10709. That's because it's a very naive take on what OOP is. It tells you the theoretical structure but not the actual repercussions if you try to do this, which will only become clear once you develop a project in an OOP style and you start running into a lot of problems with it. The examples that you are being shown on the internet are typically unrealistic. In this case employee information is typically stored in databases and things like wage calculations are much, much more complicated because you have to pay taxes for your employees. You will never encounter a problem like this in the wild for those reasons alone. The sole domain in which I have found OOP somewhat useful are graphical user interface widget libraries. Everywhere else it seems to be getting more in the way of what you are trying to do than that it's helping.

  10722. One can easily build a bomb like that. It's a simple lever that removes the photodetector from the light path when the bomb is not active. It's a somewhat quirky idea. A simple photodetector is, of course, always absorbing, whether it actually triggers something or not. Having said that, the analysis is what really fails. This bomb detector is no better at finding a bomb than anything conventional and a real bomb "test" would not test the bomb, at all. One would simply put some black tape on the bomb's photodetector to make it insensitive to light. The problem with all of these "experiments" in quantum mechanics is that they don't teach us anything about quantum mechanics, at all.

  10770. It's a matter of temperature. We know at what temperature protons and electrons become the predominant constituents of the radiation in the physical vacuum. It will, however, take another 300,000 years of cooling for the plasma to recombine to neutral hydrogen gas, at which point the cosmic microwave background starts spreading through the universe. More precisely it's not hydrogen that forms, but roughly 75% protons and 25% alpha particles (helium nuclei).

  10771. Empirically you will find that every plant on the planet has some design flaw like that, it just goes undiscovered until something happens. Safe by design doesn't exist for GW scale reactors. You can make 100kW and maybe even 10MW scale reactors safe against thermal meltdown, but beyond that convection cooling just won't save your butt. No matter the scale, you can never escape neutron activation and long lived spallation products, so the cost of "burial" never goes away.

Tanks didn't work for Russia. They are unlikely to work for Ukraine, either. They will be easy pray to Russian anti-tank weapons, just like Russian tanks were for those fired by the Ukrainians. The tank is dead. What Ukraine really needs are modern fighters and bombers and more air defense. That, however, is a really expensive proposition for a number of reasons, economic, strategic and tactical.

All the relevant physics was illuminated by von Neumann in his 1932 book, save maybe for one trivial piece that any undergrad student should be able to figure out after taking his special relativity class. That most physicists can't explain it to you is a side effect of poor teaching methods. We have known how all of this works for almost a century now, we are just not teaching it to most undergrads. They don't need to know. It has no consequences for practical uses of quantum mechanics in e.g. solid state physics and chemistry.

  10802. One of the key properties of intelligence is that it can learn on the spot. LLMs can not. They have a fixed training data set and once the training algorithm has finished, they operate based on a constant knowledge set. You can easily test this for yourself. Find a topic for which you know that the training data set of the LLM was faulty and then try talking it out of committing the same mistakes over and over, again. You will soon give up. It's a very frustrating experience to be faced with a machine that has ZERO learning ability. This will change in time but the solution won't be called LLM any longer.

  10804. Quantum mechanics has nothing to do with Lagrange and Hamilton. Quantum mechanics is a partition of unity that is compatible with relativity. Most interesting and relevant quantum phenomena don't have a classical limit (Planck radiation, photoelectric effect, superconductivity, stability of matter, nuclear decay etc.). You can't get mathematically from classical physics to quantum mechanics. It's simply not in there. IN HINDSIGHT you can theoretically get to quantum mechanics from relativity with logical reasoning, but that is not how we got there in the first place. Not even close. We simply guessed it.
    1
  10805.  @mtarnowski95  That is complete bunk. Structurally quantum mechanics follows trivially from Kolmogorov's axioms (and that they are applicable in this case follows from relativity). Historically, however, von Neumann wrote his quantum mechanics textbook in 1932, whereas Kolmogorov published his axiomatization in 1933, i.e. the physicists were ahead of the mathematicians by at least half a dozen years and even then Kolmogorov did not see, at least to the best of my knowledge, that his axioms had a much broader range of solutions than probability theory. I have heard it said by mathematicians that von Neumann understood this generalization independently of physics very well, but I didn't check his mathematical work. Based on the contents of his physics book I would say that he was probably well aware that quantum mechanics and probability theory are merely two special cases of a broader range of mathematical structures. I can tell you from first hand experience with mathematicians who were working with probability theory that this insight is still not general knowledge within the math community.
    1
  10806.  @mtarnowski95  As a corollary, it should be possible to derive the Hamiltonian structure of classical mechanics directly from relativity in a certain limit, but that's an arbitrary choice of limit. We can as well derive classical friction from first principles that way and then we DO NOT end up with Hamiltonians and Lagrangians. We do not even end up with Newtonian physics.

  10814.  @Leif-yv5ql  I am pretty sure fusion will be more than viable for nuclear fusion drives in space where radiation shielding isn't required and we can let a lot of neutrons escape. Here on Earth? Probably not. What's not sustainable about solar and wind power? We have dozens, if not a hundred times more agricultural area than we will ever need for solar and the combination of both seems to be quite efficient, especially in more arid zones, which we will have more of because of global warming. Population growth has basically stopped and resource utilization is being optimized with ever tighter recycling chains.

  10819.  @haseebs.7286  Point is that most information is useless to most people and extremely valuable to those who know how to use it. I am sure we have a wonderful collection of Persian poetry... but since I don't speak the language I will never be able to experience it. You are correct, that same phenomenon also hits software reuse hard. Most libraries are not nearly as reusable as their authors were most likely hoping for. Often it is little things like language bindings... and even externalities like the license terms. A great example of reuse are the Python libraries. The "batteries included" concept works. The lower the threshold for the user, the more likely that the code will be reused.

He could, at a fundamental level, still understand me, even if he can't follow more complex logical thoughts of mine. The LLM does not understand anything. More importantly, a person with IQ 70 can still learn. An LLM can't. Once its training is over, it can't be changed.

  10829. There is no such thing as a "collapse postulate" in standard quantum mechanics. You won't even find the word "collapse" mentioned in well written introductory QM textbooks like Sakurai. It serves no purpose and it doesn't have a workable definition in physics. It has established itself as a meme because it has been repeated endlessly by people who don't understand quantum mechanics.

  10830. Every proton in the universe can calculate the proton mass for you in an instant. The problem is not if quantum computing can be useful. It is useful, already. The problem is whether quantum computing can be made programmable and useful for problem areas outside of physics. There is nothing that could make us believe that it can't be made programmable, I am, however, not so convinced about its direct usefulness for areas that are not in hard science.

And not just on the American side. If you think that the Russians don't have an equivalent of that technology (on the cheap), think again. How do we know? The Russians would have resumed testing a long time ago if they weren't sure that their arsenal works. Yes, it's that simple.

If not, then maybe you will not care much about quantum computers, either.

  10841. Rust is not a panacea. The other day I had a problem on a microcontroller that would have occurred with Rust as well. The data cache was overriding the DMA from a peripheral. Instead of getting fresh data after a DMA interrupt I was getting the same data over and over, again, from the data cache. That's just how the hardware implementation of that particular controller works. Is it a bug? Is it a feature? Who knows. The only way to override it is by either not using DMA (there goes your performance for that particular function), by disabling the data cache (there goes your performance for the entire code) or by manually programming the MMU to remove the DMA buffer from the data cache (there goes your convenience). The only other reason why that particular code ever crashed was a single division by zero error, which would not even have caused a user problem, even if it hadn't been caught.

  10863. The linearity comes from the construction. Quantum mechanics is an ensemble theory, i.e. it starts with the assumption that there are an infinite number of identical copies of the same systems that we can perform the same measurement on. As we are adding up all the results to form averages we assume that none of these copies interact, i.e. that there are no correlations that would change the weight of any one of these measurements (i.e. the seventeenth measurement result does for instance not depend on the outcome of the fourth). Whether this assumption is true in an actual experiment where the theoretical ensemble is being substituted against multiple measurements on the same system has to be verified explicitly on the correlations in the data! There are trivial experiments for which it is true and equally trivial ones for which it isn't. The educational problem with quantum mechanics is that we usually do not talk about this explicitly, which makes the linearity of the theory appear somewhat "magical". It isn't magic but the result of an assumption that may or may not be valid.
    1
  10864.  @richardchapman1592  It doesn't leave any room for anything. The assumption of independence in the theory is experimentally testable with something as simple as a Geiger-Mueller counter. You can literally do it at home on the kitchen table. Not all systems are behaving this way, either. A laser is a light source that does, for instance, NOT produce independent photons. That, too, is experimentally testable, even if it requires a bit more equipment. Neither are the quanta in a particle track independent. The theory covers that by explicitly calculating the higher order correlations. You don't get non-linearity, you simply get independence in higher dimensional Hilbert spaces. It's all covered and has been since the late 1920s. The only problem with quantum mechanics is that the majority of all people are intellectually lazy and they don't take the considerable amount of time to learn about it properly. That's not a fault of the theory. That's the fault of the people who are intellectually lazy. ;-)

Does Zubin somehow think that people will be digging tunnels on Mars using shovels? And how will they move all that soil? With buckets? Dude... this is idiotic. I was once in a remote village in the arctic. They didn't have a single bicycle but they had dozens of cars and three excavators. The only places one could reach on foot were places where one would have died from exposure.

  10876.  @zoyxox0  The universe doesn't work on probabilities. That is a fundamental misunderstanding of quantum mechanics. Individual quantum experiments have to be statistically independent to apply the theory (because that's the actual mathematical assumption behind it). There are physical experiments for which this is true (like radioactive decay) and there are some for which it is not (laser ight sources modelled with single quantum wave functions, particle tracks). Which experiment satisfies the assumptions of quantum mechanics and which one does not has to be tested individually. I haven't seen any indication in Einstein's writings that indicate that he was aware of this fact in the first place. Look, you have to cut these guys some slack. They basically guessed it right but they never developed a healthy intuition about it. Einstein's intuition was only fractionally worse than e.g. Heisenberg's or Bohr's. That's usually the case with scientific revolutions. It takes several generations of scientists to really learn to appreciate the fundamentals properly.

He claims that he had an abusive father who was beating him and who stabbed a man in front of him when he was two years old. Whether that is a genuine memory or not can be debated, but in either case we are not talking about a man with a happy childhood here. It clearly left marks on a man who was most likely born as a schizophrenic.

This turned out to be both costly and counterproductive in the long run because it left a power vacuum both in the center of Europe and in the Pacific. We made the same mistake with Ukraine not very long ago and it has already come to bite the Ukrainians because we are not honoring our promise. The world is learning that we aren't reliable and that everybody who wants to be safe has to go nuclear. Do you really want that? Really?

  10994.  @SmashBrosBrawl  What did the governments do in 1929? Nothing. They kept watching as bank after bank failed. You know what happens when a bank fails and there is no FDIC insurance? People with savings lose their savings. You know what people do who lose their savings? They stop buying stuff. They have to lay employees off. You know what happens next? People become homeless. They can't pay their mortgages and loans. More banks fail. Rinse, repeat. Dude, you are absolutely clueless about why we recovered in 2009: because "too big too fail" was an actual phrase. If it hadn't be, things would have been just as bad as in 1929. Once the economy stops, you can't just restart it. The damage is done because businesses are out of business. You can't just ask them nicely to reopen. Whatever had been built by business people over decades was gone. The only thing that got it rolling, again, was the WW II economy. That didn't come for free, either... it cost 60 million lives.

  11006. The problem with all high speed trains is noise. Above a couple hundred km/h the aerodynamic noise seems to exceed all other noise sources. They are working very hard on reducing it because it makes faster surface trains virtually impossible in densely populated areas unless they are acoustically shielded by trenches or berms. The next problem are curve radii. A high speed train can't hug existing terrain. It has to be built on almost straight tracks. That is the same problem as faced by Hyperloop, of course. These two factors almost certainly require tunnels (or bridges) in geographies that are not completely flat. A high speed train in a tunnel is an aerodynamic problem that can only be solved in two ways: 1) large tunnel diameter (expensive) or 2) vacuum. In the latter case your costs explode for large diameter trains. As you can see, the physics of it almost forces you to a Hyperloop like solution.

  11021. In other words, you are completely useless as both a teacher (I smell burnout and disenchantment with dealing with stupid students) and as a software engineer (you have zero relevant experience). Anybody who can program can learn Python in a few hours, so why in the world do you think that knowing basic Python is a valuable skill? It's not even a language that a large project should use. Python is a prototyping language. You can solve in-house engineering tasks with it (like test benches) because it's the better scripting language and that's it. Python is NEVER useful for production code and it's NEVER good for a user app (there is not even an easy way to distribute it to users, if you haven't noticed, unless you ship it in a giant container that contains the complete runtime system).

  11023. The measuring device absorbs energy. Energy can only be used once, hence the light/electrons etc. that hit the measurement device is/are being absorbed. They don't contribute anything further to the field after the slits. In effect "measuring" something at a slit covers it up. Of course covering up one slit of two reduces the experiment from a double to a single slit pattern. There is no mystery here. All you have to know is that "quanta are small amounts of energy" and that energy can't be duplicated. It's a property that we can use in one place and one place only.

  11026. Quantum field theory is a perfectly fine theory. It allows us to calculate everything that happens inside the LHC, for instance, which is amazingly complex physics. One should not mistake the SM for QFT. The standard model is one possible application of QFT and it is never "complete". As new phenomena are seen, we can always try to fit them into the SM with the tools we get from QFT. So while QFT predicts and limits possible properties of the SM, the SM does not predict all of the physics seen in experiments. In order to break QFT, one would have to find violations of special relativity (very unlikely) or the assumptions that QM is based on (also not very likely since they are basically the same as for probability theory). In comparison, in order to break or change the SM, a single new measurement of an unknown (QFT) field at LHC or another high energy physics experiment is enough. These are just completely different levels of physical understanding of the world with vastly different consequences. SR and QM are fundamental and QFT is a more or less a direct mathematical consequence. The SM, on the other hand, is just one possible fit to the physical data.

It would first destroy all radars and air defense systems, then target key ground infrastructure and supply routes and eventually take out what remaining ground forces exist.

  11093. Quantum systems aren't in superposition. They are uncertain. The mathematical object that we use to describe that uncertainty has the properties of a vector space. That's what we mean by "superposition". It's not a physical property but merely an abstract mathematical one.
    1
  11094.  @camdenwhite4657  Such a value does not exist and can not exist. Nature is just as "uncertain" about the outcome of a measurement as we are. Wave functions do not make statements about individual measurements. They only make statements about ensemble averages. The theory is completely clear about that. The entire formalism is designed to be an ensemble theory. That's why its living in a vector space with a unitary evolution to begin with. We do, unfortunately, not teach how the theory was designed when we teach how to calculate with it. Some people call that "shut up and calculate", but in reality it's just very, very poor academic teaching habits.
    1
  11095.  @camdenwhite4657  The wave function doesn't even contain enough information to get an ensemble average. We have to specify the measurement in addition to get any physics out of it. The only actual measurements that we can perform physically are energy, momentum, angular momentum and charge measurements. Why? Because these are the only conserved quantities that stay unchanged between the quantum system and the measurement system. Everything else are just histograms over these individual quanta of energy. Don't mistake von Neuman's math for physics. One has virtually nothing to do with the other. Wave functions are not even the right way of looking at nature. Scattering cross sections are.

That's why you haven't heard about it for the longest time because for the astronomers dark matter was hiding in plane sight: as ordinary matter that was invisible to optical instruments operating at visible wavelengths. Trouble is that we then launched several generations of deep infrared telescopes that can only be operated above Earth's atmosphere (the atmosphere is warm and it literally glows at these wavelengths and ground based instruments get blinded) and none of these telescopes saw the required amount of IR radiation from these small bodies. There is not enough gas, dust and "small stuff" to can explain this. That's why we eventually had to move to less conventional explanations.

Russia tries to get Ukraine to reshuffle their air defense systems, which are defending the military assets near perfectly but are not sufficient to protect all of the civilian population.

  11114.  @grahambarrett442  If your hypothesis is that you get strong immunity from infection, then eight people is all it takes to invalidate it, especially since these eight people have been infecting each other. I know who the firsts two vectors were and everybody else got infected by those two people. In essence, what you can see in that branch of my family is that eight out of eight possible people did not have natural immunity. You can't even argue that they are genetically very similar because half of them are genetically unrelated spouses and girlfriends/boyfriends. :-)

And then you weren't paying attention, again, when we explained to you that "a quantum is a small amount of energy". And then you weren't paying attention, yet again, when we explained the Copenhagen interpretation to you in undergrad physics. And then you weren't paying any attention again, when we explained the solution theory of linear wave equations to you in undergrad classical electrodynamics. And you weren't paying any attention in experimental physics 101, either, when we explained Rayleigh scattering. It's all rather trivial... and you just keep asking nonsensical questions about it. :-)

The physical vacuum is completely empty. This has profound consequences for the universe. It literally creates everything you see around you and we can actually mathematically enumerate all the effects that can follow from emptiness. :-)

Cultural differences do have a right to exist, but they are representing hurdles when it comes to immigration.

  11190. Use auto if you don't mind it generating the wrong result. ;-)
    1
  11191. @ I can tell you that the problem exists with all "auto" features. In Excel, for instance, the program formats cells depending on whether they look like a string or a number. Tons of spreadsheets are failing because somebody types a string that looks like a number or the other way round. It's even worse with dates. There are features and then there are stupid features. This one is the latter.
    1
  11192. @ It's not a matter of coercion. It's a matter of producing errors that are not easily visible in the code. If you want a dynamic language like Python, then use a dynamic language, but don't pretend that going there halfway will save you from the severe problems that dynamic languages have. At least pointers are absolutely necessary, but this isn't. I rather have a programmer spell out all types explicitly than have a language/compiler that can generate a type system with exponential complexity automatically. The latter is not safe design. It's also not clear to me that it would be useful. Everything that can be done with types at compile time can be done much better with data at runtime.
    1
  11193. @ OK, I play. What does it do in your opinion that you can't live without and that you can't do much better and safer without it? I wasn't just talking about "auto" here, of course. I was talking about the entire failed design philosophy of C++.
    1
  11194.  @ignacionr  I understand the design of C++ just fine. Stroustrup explains in his book that he wanted to move as much from runtime to compile time as possible. auto and templates are basically the compile time equivalent of dynamic types. And that is the problem. Dynamic types are a bad idea. It doesn't get any better just because you unroll all possible types during compile time (at most it makes it worse in some sense). Here is the Python example of what auto does: a = [] # a one dimensional array a= [a,a] # a two dimensional array print(a) the program results in [[],[]] I can put the above even in a loop: a = [] for i in range[20]: a = [a,a] and now I am getting a one million dimensional array! If I make a tree, I can construct all possible array dimensions from one to a million... in no time. I can make more complicated structures like that, like arrays of dictionaries containing dictionaries of arrays etc.. See the problem? Exponential type multiplication. No programmer can possibly keep up with the consequences of that. auto and templates do the same thing, except that you are limited to a fixed number of type generations that are being unrolled by the compiler, but you can still proliferate types exponentially. Bad, bad idea.

  11198. It can't. Eventually it will do useful things, but the question is whether they will be "noticeably useful" for "the man on the streets". I kind of doubt the latter. A typical application for a quantum computer might be something like chemical catalyst research. There is plenty of that using conventional computing and all kinds of chemical methods. It's probably an R&D area that the chemical industry spends billions of dollars on every year. Do you really care about that? It's something "nerds in the chemistry department do", right? So why would you care if those nerds add one more methodology to their field by using QC? You won't.

  11217.  @V000idZer000  My response is about people who are writing diatribes about languages/paradigms without understanding that there can be no universal approach to programming loops (and filters are basically just loops) on machines that have two or three levels of cache memory and predictive pipelines. Unless you don't care to throw 99% or more of your CPU's performance away, that is... which you probably don't. ;-) And if you think that that's irrelevant... I once had to debug somebody else's code who didn't know the first thing about computer architecture. He basically sacrificed two orders of magnitude in computing efficiency by having two nested loops in the wrong order. The machine was constantly swapping cache pages while the CPU was waiting for data that was presented to it in the wrong order.
    1
  11218.  @V000idZer000  I agree, this argument that one has to put training wheels on a programmer by introducing language restrictions, interfaces and god knows what kinds of business processes (like "agile" development, unit testing etc.) is the most stupid I have ever heard. It's like saying that a young brain surgeon has to be made to operate with one hand tied behind his back because that's "safer" for the patient and, oh, by the way, he only gets to use the butcher knife because it's a tool with thousands of years of experience behind it. Neither language design nor paradigms can make better programmers and better code. Only education can make both. The OOP crowd is stupid because they do, on average, not know that OOP is merely program documentation and the FP crowd is even more stupid for mistaking a mathematical proof technique for an engineering strategy. In practice every additional restriction, every rule, every requirement makes things worse. How do we know? We have billions of man years of wasted coding effort that proves it.
    1
  11219.  @V000idZer000  All of these things are just tools in a large tool box that every programmer should have, of course. They are not "evil" by themselves. What makes them problematic is the purist mindset that is being propagated in the industry. Humans have a tendency to see a good thing and then to pretend that it has to be the best thing ever, the only good thing, that it has to have a godlike quality, that it must be made the only thing that ever matters, and if they have to use fire and sword to enforce that, so be it. It's basically the same psychological delusion that fuels religions. I have used OOP successfully... on a graphics library. It works beautifully for that. I have used filters and iterators. No problem. But neither was the solution to any real problem for me. I have to disappoint you on the "better language" thing. A language is either Turing complete or it isn't. All Turing complete languages are identical in what they can do. That includes jokes like Malbolge. The only difference is efficiency. C is a very efficient language and it almost inevitably goes down from there. I believe only things like Fortran and assembly language can do a few percent better. As I said, OOP is documentation. It never makes it into the machine code. Now, I agree... I wouldn't want to write a computer algebra system directly in C, either... so I would probably write a compiler for a custom language for that task, first. ;-)
    1
  11220.  @V000idZer000  I was exaggerating, of course. Worst possible language designs are academic jokes, although I think one can still learn something that way... obfuscation is far more powerful as a security technique than the "hard" encryption crowd will give it credit for. We have plenty of examples of extinct historic languages that have not been deciphered yet, despite decades or even centuries of effort. And that's not even encryption... that's "just" reconstruction of a dictionary and a grammar from a plaintext. The space between "nobody screwing up" and "great software design" is filled with more than just better languages and interfaces. What I find much, much worse, is just how long we are hanging onto really abysmally bad solutions like HTML or CCS. I mean... those things must have come out of the same evil minds that invented Malbolge and Brainf*ck. ;-)

  11223.  @bnielsen56  Well, those of us who have studied physics know that c is a dimensional constant and therefor its absolute value is meaningless. We usually set it to 1 in rational unit systems. It has therefor absolutely nothing to do with electric and magnetic properties. It's the maximum velocity with which energy (in any form) and causality can spread. I don't know what bubble you are talking about. There are no bubbles in this universe. That's just bad theory pretending to be physics. You can just laugh about it, invoke a chant about time traveling intelligent perpetual motion machines and then move on. ;-)

  11224.  @bnielsen56  The source of the CMB is a thermalized plasma with a bit of an acoustic rumble in it. We have, as far as I know, no indication that the physics at that time was significantly different from the physics we have today. Inflation would have been way before the decoupling of matter and radiation and I am not a strong supporter of it. I don't think it solves any problems that need urgent solving and even if it does, it does it in a completely useless way by introducing infinite degrees of freedom. What it certainly does not do is to introduce local FTL. Physics majors don't work on things like the CMB and inflation. That's for PhDs, kid. At least try to sort out who you want to be jealous of before you are making foolish emotional comments on the internet. :-)

Almost all human economic activity is more risky than that. The last decade of low interest rates is an indicator that US monetary policy was not keeping up with the world economy. Now, you can argue that the US should not be providing the dollar as an exchange quantity for the entire world economy because that causes a really strong correlation between domestic US policies and the world economy in total. I will agree with that, OTOH, it is a major financial income source for the US. The only possible replacement for the US dollar would be at least two to three million legal immigrants a year and even then we would be increasing the total dollar money flow like crazy because of the job creation for these immigrants.

  11230. Best one on YouTube as far as I can tell is probably Dr. Becky. She is giving a good example on how science should be communicated. Admittedly, astronomy is, to some extent, easier to explain and to understand than high energy physics and relativistic field theory. Everybody can, to some extent, understand that stars are large spherical arrangements of gas and plasma and that they are moving according to the laws of physics. Stay away from anybody who tries to explain quantum mechanics to you on the internet. Almost all of them are almost entirely wrong. They are simply repeating a bunch of old misconceptions over and over again.

  11246. That passionate exploration thing is hardly how most people start out. That's a movie trope as well. Teenage boys don't have that kind of maturity and neither do 30 year old male virgins. I have never met anybody who didn't tell me that their first time wasn't an emotional and physical mess. Mine was comparatively OK because I was the male virgin and she knew what she was doing and what not to expect from me. Was it great for either of us? No. It was kind of a letdown. The best part of it was that I made breakfast the next morning, which she didn't expect and that gave her a real smile. I didn't have really great intimacy until quite some time later... after practicing. Of course, after all that practice you don't need to explore anything. You know what the goal is and how to get her there. Pretty much the only part that actually matters to me is that somebody lets me get them there. It means I am doing something right in the emotional department. The physics of it is... just the physics of it. A small motor can do the same and probably better.

Immunity doesn't last and in people who don't have a good immune repertoire it probably won't last long at all. We are 20 months into the infection, so that's six months between infections... totally compatible with the biology of the disease. People need to stop believing in magic here. There is no magic with flu or the common cold or measles or herpes or any number of other diseases. That's the entire story, really.

  11260. In physics nothing means "no thing" and its consequence is Poincare symmetry. That's a perfectly testable condition for an operational definition of "nothing". The consequences are as trivial as the differences between the acoustic Doppler effect (non-empty background) and the relativistic Doppler effect (empty background).
    1
  11261.  @sjoerd1239  Physics is not philosophy. It doesn't split words for the purpose of splitting words. It describes reality. In reality we are observing macroscopic "things" and their properties. The strategy we use to cope with the significant complexity of the phenomenological richness of the physical world is by using a divide-and-conquer strategy. Physicists divide the world into systems. A system may or may not have material objects in it. Even if it doesn't (i.e. it's a system of "no things"), such a system still retains a few fundamental properties because of symmetry (symmetry is the absence of symmetry breaking physics). That symmetry turns out to be local Poincare symmetry. That's as "simple" as we can make it in modern physics without "falling off the horse" like the philosophers do with their pointless hair splitting. As it turns out these few properties are sufficient to explain ALL of the known phenomena that matter and radiation is capable off. If that is not beautiful, I don't know what is. Throw Poincare symmetry out and you can literally NOT explain anything. Keep it in and "every thing" follows almost seamlessly from the symmetries of "no thing".

  11274.  @YannickIgten  We do know "how the Earth reacts to heat". Some 25,000 years ago Europe was covered in ice. The ice melted and within a few thousand years giant forests were moving across the continent from the South all the way to the polar regions. 2500 years ago North Africa was a great zone for agriculture that supplied much of Rome's staples... but productivity declined towards the end of the Empire and caused Roman city populations to abandon poorly supplied cities when the regular shipments of cheap grains seized. The aridification of Europe will continue with forest and agriculture retreating to ever higher latitudes. Sweden and Norway will become climatically preferred countries and living in the South of Europe will become close to unbearable in summer.

That's just idiotic.

  11289.  @stevematthews4489  That's how it sounded like to me when you said that only an Imperial Russia can be stable. That is completely false. Russia would do far better if it had oriented itself toward Europe. The culture and style of Moscow and St. Petersburg are, after all, directly borrowed from France. At this point, of course, Europeans see Russians as the new Mongolian hordes and Stalinism was not an exception but the rule. It will take Russians at least a hundred years to shake that, even with best efforts, which will not be forthcoming, of course. Russia is, at this time, begging to be restrained and, worst case, destroyed.

  11299.  @Thomas-gk42  Witten's results can not be experimentally verified except maybe on model systems. I do believe to have read that some of the methods he has come up with are applicable to magnetism, so we might get predictions about spin systems that can't be (or have not been been) achieved with other methods. So, no, I would not expect him to get the Nobel, at least not directly for his work on string theory. The Fields medal was awarded for the importance of his work to pure mathematics (the mathematicians have their own search for . There are examples of mathematicians like Villani who have gotten the Fields medal for mathematical work that is important to physics, so the mathematicians are quite open to such cross-pollination. I read Sabine's work on foundations of quantum mechanics. It's obtuse nonsense. She simply doesn't understand quantum mechanics. Even if she did, her work compares to Witten's like first grader's algebra compares to partial differential equations. Even I can understand all she did on QM, while I am usually lost after the third sentence in Witten's papers. :-)

That task is centered on the question "How do we destroy Russia completely without allowing the conflict to escalate beyond the East of Ukraine?". If you think for a second that NATO would allow Russia to march its troops all the way to the Polish border or to Berlin, think again. That was never on the menu. The Poles and the Baltic states have made this abundantly clear. There will be no fallback to the borders of the Cold War, at least not unless it happens over the cold dead bodies of over 40 million additional people that Russia would have to overrun first. That, of course, would not stop at 40 million but it would involve the entire world in a nuclear conflict and THAT is what has to be avoided at all cost.

  11384. It's not a feature but a mistake. Everett did not understand that quantum mechanics is an ensemble theory and he assigned the wave function to single quantum systems. It's like the assumption that every dice roll can already predict what the outcome of the next roll will be. It's just total nonsense.
    1
  11385.  @neuroatrok  A single atom is a single quantum system. When it decays from its excited state into its ground state it gives us one photon of energy. After that it can't give us anything anymore. There is no more energy in there. When we measure one photon, we can get the following information: energy, momentum and angular momentum. That's it. There is no more information in that one event. In contrast the wave function of the electromagnetic field contains an infinite amount of information about the field. That's because the field can only be measured (precisely) by taking the average of an infinite number of photon detections.
    1
  11386.  @neuroatrok  Pretty much. The language in Everett's thesis is not even his own. He most likely got it from von Neumann's book or some other authors who wrote it that way. In essence these things are outcrops of really horrible language use in modern physics that implies mental models that are inaccurate and completely misleading. We know today that the structure of quantum theory can be derived from the same axioms (named after Kolmogorov) that mathematicians use to define probability theory. What this implies is not even that we are talking about probabilities. It only requires that individual experiments (like the emission of light by individual atoms or the decays of individual nuclei) are independent (i.e. that there is no causal relationship between any two events). This leads to seemingly "random" time series, but that's entirely irrelevant for the theory which only predicts averages. The deeper reason for the independence is relativity, i.e. it is a physical reason that lies outside of the structure of the theory to begin with. It is therefor completely pointless to look for some unknown internal ("hidden") variables that we have not been able to identify, yet, or for some magical mechanism that restores "classical" deterministic behavior. That is simply not how a relativistic universe behaves.

  11422.  @Montycarlo10  Nothing in physics is probabilistic. Random numbers don't obey any conservation laws. When we talk about local conservation laws like energy and momentum conservation, that's not a joke. Nature sticks to that. Even at the quantum level. What is true is that we are doing a really, really horrible job at teaching quantum mechanics. What we should be teaching is that series of quantum measurements are independent, i.e. the results of future measurements can not be predicated based on past measurements, but we should also emphasize that independence is NOT the same as randomness. It's a different criterion altogether. Random variables don't have to be independent (there are formulas to deal with correlations) and independent outcomes do not have to be random. Instead the local measurement is entangled (correlated) with the state of an unobserved (and in many cases unobservable system). This allows for the preservation of energy, momentum, angular momentum and charge but still delivers SEEMINGLY random results. This is also the deeper reason why quantum mechanics is not at all like probability theory, even if it shares a few axiomatic assumptions with it.

  11428. The cosmological constant is one of an infinite number of mathematically allowed terms in extensions of general relativity. There is no theoretical argument that can rule out that any of these terms are not zero, so we have to rely on observations to set limits for them. These observations happen to be quite hard. I honestly don't expect to see reliable tight limits on the cosmological constant and some of the higher order terms in my lifetime. Some things in life are difficult and take a long time. That's the nature of the scientific beast.
    1
  11429. It's neither. The universe is uncertain. The present is entangled with an open future and therefor no more knowable than the future will be. One can't roll back the clock because there is not one clock. There are an infinite number of them and they don't agree with each other.

  11433.  @johnlawrence2757  There are no packets of energy. Energy is a system property. In physics a particle is defined as the approximation of the motion of a classical body by the motion of its center of mass. In the Kepler problem the planet is treated with the particle approximation because we neglect rotation and internal degrees of freedom like chemical composition, atmosphere etc.. That is different, yet again, from Newtonian corpuscles, which is what Einstein was falsely associating with quanta of electromagnetic field energy in his paper on the photoelectric effect.

  11434. So what you are saying is that you and Sabine are getting worked up over a poorly written science paper. Sounds like a waste of emotional energy to me. But then, maybe you like raising your blood pressure that way. It's certainly safer than free-climbing a rock face. ;-)

  11436. That is probably a misinterpretation of what Maxwell and Einstein thought. It's much more simple than that, anyway. "The vacuum" is a bunch of quantum fields that produce nothing but relative physics, which means that they have to have Lorentz symmetry. Pretty trivial, really.

  11437.  @cristig243  Light is a quantum field. Have you seen light? Then you know what a quantum field is, too. Did you hold two magnets in your hands? That's a quantum field at work. And no, I didn't say that Einstein and Maxwell had these insights. I didn't say that is was easy for THEM to make sense of it. I said that it is easy NOW (minus the mathematics of quantum fields, which is "intense", to say the least). Why? Because there were more giants in physics since Einstein and Maxwell and we can stand on their shoulders. In science knowledge goes from the hard, complicated, convoluted, mind-boggling towards the conceptually easy. You should celebrate that. It's absolutely amazing.

Our theories are actually all deterministic, but at the level of quantum mechanics and thermodynamics that determinism is limited to the ensemble, which is a mathematical abstract that does not exist in reality. Nature itself is not deterministic in the sense that a firm prediction of the future would always be possible. We can predict many important aspects of the future. That is sufficient to plan our lives rationally.

If you follow the literature, then you will find that von Neumann had basically cracked all of quantum mechanics in his book published in 1932. Strugglers like Schroedinger and Einstein probably didn't read it or they didn't understand it and they were still fighting with windmills years later (1935 to be precise, that's when both Schroedinger's cat and the EPR paper were published).

  11499. There is a reason why he has "notes". He didn't put this together himself. It's researched by his writer team and the whole thing may have been rehearsed more than once. If you can find another clip of Oscar Peterson doing this kind of performance, you know that it was a real "show", i.e. professionally set in scene. You can watch plenty of other "interviews" with celebrities from that time. They are all rehearsed with all the "questions" and "answers" scripted and contractually agreed on by the show producer and the agent of the celebrity. That's a pity because we can't learn anything about the actual person behind the actor. They literally never left the stage when a camera or microphone was rolling. We simply don't know what Greta Garbo was like as a private person or how John Wayne really behaved off set. We may have an occasional "oops" when they lost it, but that's not the real person, either. That is, at most, the real person on their worst days. There may be a few hosts who are trying to show us the real people behind the theatrical masks today, but I think even that is rare. Graham Norton certainly does a great job pretending that he is showing us the real people. So much so that I actually want to believe it. That's the art of the talk show host profession. Having said this... I don't think I would want to be too exposed as an actor or musician myself. The public is more than just a source of income. It's dangerous. One does have to keep a healthy distance.

  11500. It's neither. NASA is simply being used to launder some government money into secret programs, most likely related to the national security agencies and the military. One can't have secret books in a democratic system like the US. Congress has to account for every penny it spends. So what does it do, instead? It spends "a little too much" on some line items and then tells its contractors to use that "too much" to do "something else" with the money. And they do. That's part of the business model in the military industrial complex.

  11515. @ We tell you what a measurement is in classical physics: it's an irreversible energy transfer. You can see the exact definition for a quantum measurement in Heisenberg's matrix mechanics papers, which predate Copenhagen: quanta of energy, momentum, angular momentum and later charge become the indices into Heisenberg's matrices. In von Neumann's formalization of Schroedinger's work they become the test functions that are the spectral eigenfunctions of the measurement operators. That makes it a little harder to see what is going on at the physical level because it is now removed by a generalized version of the Fourier transform and independent of an actual physical basis (Heisenberg was still plugging the raw measurements in, von Neuman does it "right" and allows for a general linear transformation that is a gauge degree of freedom for every linear theory, classical or quantized). It's still the same thing: we measure histograms of energy, momenta, angular momenta and charges. That's what we did in the early 1800s when the first Frauenhofer lines were discovered and that is what we are still doing at LHC.

  11516. @ There are no collapse theories. The term isn't even defined in quantum mechanics textbooks. It's just some nonsense that floats around on the internet.

  11517. @ Read Griffith's introduction to his book. He tells you explicitly that he doesn't understand quantum mechanics... and then he unfortunately proceeds in textbook length to prove that statement to you. ;-) Sakurai is a better author and he doesn't use that term. It's completely pointless and the theory doesn't use collapse anywhere. The theory starts with the measurement of quanta of energy and the assumption that each measurement is independent of all others. When that's the case (and ONLY when that is the case) we can formulate a linear ensemble theory. It's the statistical independence assumption (that is NOT satisfied for many systems) that leads to linearity of the theory. It is the conservation of the number of experiments in the quantum mechanical ensemble that leads to unitarity. Sometimes this is mislabeled as "particle number conservation" in some textbooks. That's nonsense, of course. There are no particles and the number of quanta is not constant in high energy physics experiments. Once you have unitarity you can immediately proceed to the definition of a wave function (vector) with constant length and then you can directly define a scalar product structure of the theory. Unitary transformations and projection operators drop out from the theory by demanding a mapping to real physical observables. All of this is already described in von Neumann's 1932 textbook WITH physical explanations of what all of this means. Nowhere does any of this need "collapse" bullshit.
    1
  11518. @ A physical observation is simply an irreversible energy transfer. Unless such an energy transfer takes place, there is no scientifically observable fact. Science is not a religion. It doesn't deal with anything other than these energy transfers. Nobody can tell you what a be-able is supposed to be. I am an experimentalist. I can tell you EXACTLY what it is that I am observing. That's because I am actually paying attention to nature and not to pesky voices inside other people's heads. :-)

  11519.  @lolroflmaoization  The wave function is not a physical object. Nature knows nothing about it. It's a mathematical abstract. Mathematical abstracts can't collapse. It's like saying the probability distribution of dice collapses from 1/6 to 1 when we roll a "3". That's just total nonsense. A single system is NEVER in superposition. What we are measuring is a quantum of energy. Let's say our system is an excited atom. Before the measurement of a photon emission from that atom the atom was in the excited state. There was nothing uncertain about that. After the measurement the atom has lost a photon's worth of energy and it is now in a de-excited state. Again, there is absolutely nothing uncertain about it. A single atom can simply not be in a superposition. Either it has that much energy or it does not have that much energy. What can be in superposition is our knowledge of an ensemble of atoms BEFORE we have the measurement results. Nature does not know what we know or don't know about either a single atom or an ensemble. Nature does not care about the uncertainty of our knowledge. Hence it does not care about the wave function. Where this gets really unpleasant, and this what really upsets people who are not used to it, is that the detection of a quantum does NOT give full information about the ensemble state. The same preparation of spin state (all up in the x-direction) will give a 50% mix of ups and downs if we perform the same spin projection measurement in the y-direction. There seems to be some randomization going on here that classically does not exist. Where does it come from? It comes from the unknown state of the measurement system's ensemble. We can simply NEVER collect all the information about the world that we would need classically to describe all of nature with a classical state. THAT Is what upsets people.

Of course they didn't know that in the beginning. Of course quantum mechanics did NOT come from first principles this way HISTORICALLY. I am not talking about science history here. I am talking about the actual physics that gets you beyond shut up and calculate. It's special relativity. You have to learn the reason why quantum mechanics is the solution theory of the unitary representations of the Poincare group. :-)

I am an experimental high energy physicist. I have actually seen and done all of these things hands on. I KNOW FROM EXPERIENCE where quantum mechanics originates in nature and I just told you. Please take the time to catch up to what everybody who has taken a special relativity class can know right away IF they are being given a little hint to look at just the right thing from just the right perspective.

  11533.  @longcastle4863  That's the problem with laymen. They see bullshit and they immediately swallow bullshit without even doing a smell test. No, "probability wave" is not an actual concept in physics. It doesn't even make sense as a word. A probability is the imaginary continuation of a measured frequency of events in the limit of an infinite number of experiments. First of all it's not even possible to perform the same experiment an infinite number of times, hence not even probabilities are physical, and secondly the process of repetition of experiments does not spread as a wave. This is irrespective of the fact that quantum mechanics talks about uncertainty and not about probability, to begin with. Uncertainties can be time reversal invariant (and quantum systems are). Probabilities, which are the results of stochastic processes, can not be. You are not just barking up the wrong tree here, layman, you are not even in the right forest. And, yes, that's not your fault. Nearly 100% of the "information" you can find outside of the better textbooks on the subject is about as fake as one of Trump's speeches.

    1
  11541.  @prashanthramg9005  Photons and electrons are not particles. They are quanta of energy. That's a completely trivial but extremely important statement. Energy does not have a position and it does not have a path. It didn't have those properties in classical mechanics, either. Energy is a system property. When we talk about "a photon" what we mean is that flow of energy between two systems. "A photon" is the energy that a light source emits into the electromagnetic field or that an absorber/detector removes from the field. The emission and absorption energy do not need to be the same. A simple example of that is the Doppler effect. The electromagnetic field does not "know" the relative velocity between the emitter and the absorber. In the same way it also doesn't know the distance and the relative angle of polarizers (or magnetic fields for spin projection measurements on e.g. electrons). These facts are set by relativity (we can deduce the necessary form of the equations of quantum field theory directly from first principles). Bell didn't discover anything that wasn't known to a much higher degree, already. We have "the right theory". There is no need to classify all the wrong ones (a wrong theory is not even a theory by definition of "theory", so it's not even clear to me what the heck Bell was trying to do there).

Plato took it as far as to pretend that it can live entirely in the realm of the abstract without any connection to reality. That was peak-bullshit and philosophers never recovered from that false assumption. Unlike science, philosophy is not self-correcting and it shows.

No matter how many layers of insulation you wrap around yourself, you are still working and (worse) sleeping inside your fridge's freezer compartment. There are very few people who actually enjoy that. They do exist, but I think it was one guy who was like that out of literally hundreds who were working on that site during that season. Everybody else was just doing "the job" that had to be done and we all wanted to get out of there. I went for a tropical vacation afterward. I had to compensate. Hawaii is much, much better.

  11630. ITER is not speculation and she didn't debunk anything. She merely exploited the fact that people don't go to the ITER homepage that says that ITER is a science experiment rather than a commercial test reactor. ITER will prove that stable operation of a Tokamak with sufficient net plasma gain is possible. What it will also prove is that the low field Tokamak is economically not feasible. The machine is way too large, way too expensive and still underpowered to ever get anywhere close to a financially feasible design. Maybe small 20-30T designs will get closer, but even that is a hard nut to crack. It is unfortunate that she didn't spend the time to talk about that. You know why she didn't? Because that would have taken actual weeks of actual physics research for her in preparation. This one she could shoot from the hip. She is getting lazy, I am afraid.
    1
  11631.  @djjfive  Well, the ITER homepage is factual and truthful, something which one can't say about some of the commercial companies that peddle tiny fusion reactor designs. It will be interesting to see if any of them can as much as light a candle. Personally I doubt it. ITER will certainly produce strong bursts of neutrons and heat, which will amount to mostly a radioactivity cleanup problem in my opinion. I found the fusion community to be quite honest about their goals and aspirations in the past. I went on a tour at Garching a long time ago and asked the scientist who showed us the facility what the community thought fusion could accomplish in commercial terms. He responded that a best commercial estimate for the cost of fusion energy was four times the cost of electricity from coal at the time. That was based on JET sized baseline designs without any cost for fuel breeding and processing, of course. With ITER sized facilities plus (as of yet non-existing) blanket physics and the rock bottom cost of solar and wind energy we are probably looking at ten times the cost per kWh now. In other words: magnetic confinement fusion will simply not happen commercially. That doesn't mean it won't happen. I can see it being the power source for future interplanetary and certainly for interstellar spacecraft. We will master 25T, then 30T and eventually even 40-50T magnet technology. Even a child can ignite a fusion plasma in a 50T field with a match (in comparison to the difficulties for a 12T Tokamak). Those reactors will squeeze tens of GW out of a few cubic meters of plasma volume. That's roughly the power of a space shuttle solid rocket booster, but burning for many hours or even days, while the spacecraft will accelerate to hundreds, maybe thousands of kilometers per second. That is where fusion will live. It will not power your LED light bulbs, other than in form of solar panels. And that's fine. Solar panels are great.

  11663.  @tomirendo  I asked a simple question. Do you have scientific evidence that one can't do science? Absolutely every bit of rational experience of humankind indicates the opposite. The damn stone age people were doing science by observing the moon and the sun. They had observatories that could tell them the equinoxes and solstices already. A stone thrown into the air flies along a parabola. It does that over here as well as in Madagascar, on the moon and three billion light years away. You don't seem to "believe" in these facts. Was this more to your liking? :-)
    1
  11664.  @tomirendo  There is a fundamental issue with all of philosophy. It's all bullshit. Superdeterminism isn't science, so it has zero impact on science. A stone flying along a parabola, that is science. You don't need superdeterminism for that. All you need is a table of height over distance. I don't know why so many people are having trouble keeping science and philosophy apart. There is no resemblance. The philosophy department hasn't done a thing for the world since 500BC and the science departments have changed the world completely in 450 years, or so.

  11666. The universe is real, it's just not locally realist. It was never locally realist, we just didn't know better. These kinds of things are remnants of Galilean physics that still keeps spooking around in people's minds. Why do they do that? Because we are still teaching physics like it's the 19th century and we are pretending to high school students that Newton was essentially correct minus some "minor" modification by quantum mechanics and relativity. That's simply not so. Newton is almost 100% wrong. It was always almost 100% wrong, we just didn't know better. What we should be doing is start teaching physics from a modern perspective and then derive Newton as a very useful but almost insular corner case. If we did that, then all these random philosophical musings about the structure of the world would go away in no time.

  11680.  @zoeherriot  The way we train people is the same as we train AI. Most people don't understand the actual facts behind their training (schooling), either. They simply repeat what they have learned. Change the input scenario in a non-trivial way and the monkey-see-monkey-do strategy fails completely. The problem with the recruitment is not even an AI training problem. It's a problem with actual recruitment. You can't blame the AI for the mistakes people make. The really problematic cases are things like e.g. self-driving. A human has a survival instinct that tells us not to drive a car at full speed into a standing object. This instinct has developed over long stretches of time by evolution and is being re-enforced in children by very painful knee injuries. But when Tesla trains their cars on human driving behavior it can't actually teach the survival instinct that way because the "Ooops, I just killed myself and all my passengers in a stupid accident." is not actually in the training set and can not be put in there for obvious reasons. So even though it was in our childhood training set and in that of our ancestors who won the Darwin Awards early and often, there is no technological equivalent because cars don't have knees and they don't grow up like we do.
    1
  11681.  @zoeherriot  I didn't say that the problem doesn't exist. I said that the problem already exists in your own education. Schooling of humans is just as faulty as the training of neural networks. It is NOT "an IT problem". It is a general problem with the way in which neural classifiers assess the world. They do quick but superficial similarity assessments rather than actual logical root cause analysis. In general, a neural network is just a giant lookup table. If what is in it doesn't match the input vector, then a more or less random output will be generated. Tesla's cars, for instance, have simply never "seen" a giant white surface that keeps getting bigger rapidly, so they can't tell that it's dangerous. That's all there is to it. If you would convert the representation of the input data into a velocity dependent "time to collision" estimate first, then the frontal collision problem would never occur because the neural network would always "know" that it is dealing with a dangerous situation. The forward looking video feed is simply not that representation and it's not in some magical way equivalent to that representation. We do have systems like that, by the way. It's the ground avoidance and collision warning system on planes. The machine knows exactly what is going to happen ten seconds from now and gives the pilot a stern "Pull up! Pull up! Pull up!" warning. If the pilot does not react or the reaction does not convert into a proper attitude change of the plane then the result is completely predictable. There are similar warnings for air speed to avoid a stall and collision avoidance systems that give banking warnings like "Bank left!". Why did we build such systems into planes? Because pilots were frequently flying their plains into the ground, a non-recoverable stall (it takes only ten seconds of faulty control input to do that unless you are flying a fighter jet) and into other planes.
    1
  11682.  @zoeherriot We have plenty of data from our education system on this problem. K-12 we are spending approx. 10,000 hours on the education of each student. Maybe a quarter of that is dedicated to math and science. Despite this effort very few who finish high school but don't do at least four years of college in STEM achieve anything that could be called "a lasting ability to solve an analytic or synthetic problem related to the natural world". Most people don't actually internalize the basic definitions and they never learn to apply the concepts they were taught to non-trivial problems. Just like "stochastic parrots" students manage to pass tests by repeating the words they have memorized from their lessons or the textbooks but they do not learn math and science on an actual functional level. So, no, I am not a strong believer in human learning. If anything, the AI revolution is an eye opener of just how much humans are imitating intelligence and knowledge more than they actually possess either.

It is perfectly possible that the GOP is hoping for that. It's not obvious to me that such a move would be politically disadvantageous to Biden, either. Americans have a tendency to support a strong acting president even if they politically disagree with him.

  11753.  @philliprobinson7724  The problem with the "They were real people!" argument is that it doesn't matter. So what if they were real people? So absolutely nothing. We still don't know what actually happened and what these people actually said and thought. All we have are secondary religious sources which might as well have been made up. It's not like gnostic ideas are living any closer to the realistic level than those that can be found in canonical writings.

  11754.  @philliprobinson7724  Christianity is not the belief that Jesus existed. It's the belief that he will come back to resurrect your dead body, that he will judge your resurrected dead body and then throw your resurrected dead body into a lake of fire for eternity. You need to stick to the actual program here.

  11755. Feynman had a real talent to give you the wrong intuition. This is a clear-cut case where he did just that. The effect has absolutely nothing to do with information about the path of particles. For one thing there are no particles and even if there were some, they wouldn't have a path in quantum mechanics. What simply happens is that a measurement of a quantum removes that quantum of energy from the field. Energy that has been removed can not be detected a second time anymore.

  11757. China won't attack Russia. The only possible response that Russia could muster would be nuclear and China is extremely vulnerable to nuclear attacks because it has such densely populated urban areas. The only time that China would interfere in the border areas would be if Russia were to break apart and they could claim that they are "defending" the Chinese population in those areas. Which would be a complete lie, of course.

    1
  11777.  @JohnSmith-ut5th  And I was talking about Einstein's original mistake of identifying quanta as having corpuscular properties, including position. That is what leads to all that funny "spooky action" business in the first place. What people call entanglement is merely global symmetries at work. That game can be played even with classical objects like socks. It's boring as heck and offers absolutely no physical insight.
    1
  11778.  @JohnSmith-ut5th  That's cool. Now all you have to do is to show me the path of a single photon in an experiment. :-)

  11779.  @JohnSmith-ut5th  The mathematics doesn't give you paths for quanta. :-)
    1
  11780.  @JohnSmith-ut5th  I know what path integrals are. They don't give you paths for quanta. They give you a mathematical formula to calculate the probability of where you can find quanta. That's not the same thing.
    1
  11781.  @JohnSmith-ut5th  I read that book over thirty years ago, my friend. You are not the only one who knows about it. The path integral formula is a quantization procedure. It tells you how to go from a classical Lagrangian to a quantum mechanical propagator. That propagator describes the ensemble, not the individual quantum system. Even Feynman does a lot of handwaving to avoid having to explain that. What's left looks to the layman like a formula for classical paths, but it's not. In physics a path means that you have to have at least two measurements on the same object. Photons are energy. Energy is lost as soon as it is being measured. One can not measure the same photon twice. That is neither theoretically nor experimentally possible.
    1
  11782.  @JohnSmith-ut5th  Don't get me wrong. Feynman's book is great. He gives a great insight into the phenomenon of how path integrals work and how they create semi-classical effects (by destructive interference of rapidly oscillating terms that are far away from the classical trajectory that minimizes the classical action). One has to understand that he comes from high energy physics background, though. In that particular case, high energy quanta do behave, in a sense, like classical particles when they are being subjected to weak measurements in detectors. A weak measurements is one that does not remove the entire energy of the original quantum but instead only makes many small momentum changes while the energy is being slowly absorbed by a detector medium in many steps. How this happens form the standpoint of a pure wave theory has first been pointed out by Mott in 1929. It's basically an application of the equivalent of conditional probabilities in quantum mechanics: if we localize a quantum weakly at some coordinate x, then we incur a small momentum uncertainty, which for a next weak measurement will give us the same coordinate plus the classical estimate for the location change due to the initial momentum plus a stochastic term that came from the momentum uncertainty of the localization. In essence, experimental high energy physicist can treat the quanta they are detecting in their experiments like classical particles that make a little random dance around the classical trajectory. In the detector the energy of an e.g. 1Gev "particle" changes in steps of hundreds of eV to MeV per interaction and hundreds and thousands of such interactions occur before all the energy is used up. That's what creates those nice particle tracks that show up in all the high energy experiments. However, in the interaction point of the beams in an accelerator experiment, that is the point where the actually interesting physics happens during collisions, this weak measurement approximation does not apply. There quanta are exchanging all of their energy/momenta at once and no classical paths exist . That's where we have to go through the entire infinite sum of Feynman graphs to elaborate all physically allowed interaction processes. That is what the path integrals and their perturbation series (Feynman diagrams) were really invented (or shall we say discovered) for. At that point we are back to the same principles that apply in low energy quantum interactions like the photoelectric effect: quanta only exist as physically useful entities during the interaction of quantum fields, when the entire energy of a state is being exchanged. When these fields are not interacting, however, then they behave like wave phenomena. End rant. :-)

  11783.  @JohnSmith-ut5th  Sadly for you John, everything I told you agrees with experiment and observations and nothing that you are telling me comes even close to describing reality. Nobody has ever measured the path of a photon and nobody ever will. Electrons exist as independent entities only below 1MeV, above that they are converting into electrons, positrons and other stuff. :-)

  11802. Let's put it this way. Artistic beauty is in the eye of the beholder. Just like Rembrandt would have scoffed at modern abstract painting, so would Newton have at modern physics. It would have been beyond the sense of "beauty" of their time. That doesn't mean that one can't appreciate modern art and modern physics today. It just takes a lot more "getting used to". Although I am sure that there were plenty of people at Newton's time who were probably appalled that the man had condensed god's work on the heavens into a single 1/r^2 law.

  11818. A train can't do anything useful for personal transportation in a country the size and population density of the US. Freight is fine, but going coast to coast wouldn't be. For anything longer than a thousand miles flying is far more comfortable and for less than two hundred miles a car and a highway are fine. So that leaves us with a very narrow range of opportunity to build high speed rail... and given the lack of large city pairs in that distance range the US is simply not a good place for HSR.

  11856. I have been in the military and these stories are not how militaries work. The officers are often people from a certain background. They have other family members in the military, often going back a century or more and they have been raised with "patriotic" ideas that are baked into their psyches. The better ones also understand that the common soldier does not share these ideas. The better militaries in the world teach their officers how to overcome that gap. The not so good ones shoot their soldiers in the back. Neither technique works in the civilian world where an employee can simply walk out and take vital corporate memory with him/her.

  11876. That's not what the EPR paper argues. You should read it in detail when you have the time. The main problem with the paper is not how it uses quantum mechanics but how it defines "completeness". Here is the original language: "Whatever the meaning assigned to the term complete, the following requirement for a complete theory seems to be a necessary one: every element of the physical reality must have a counterpart in the physical theory. We shall call this the condition of completeness." It requires that elements of physical reality are mapped to elements of the theory. Copenhagen does that just fine. The actual "problem" with Copenhagen is that it has a theoretical element that DOES NOT exist in physical reality: the wave function. A wave function is an ensemble average, i.e. it's a mathematical abstract. Nature only has exactly one copy of each physical quantum system, while in the theory we postulate an infinite ensemble of statistically independent but otherwise identical copies. That is exactly the same procedure that we use to define probabilities and one can, indeed, derive the structure of quantum mechanics from Kolmogorov's axioms without much difficulty. So it's not that the theory isn't "complete". It's actually more than complete by this definition. It requires something on paper that nature doesn't provide itself in experiments and observations. So while the paper is technically correct (it shuts up and calculates correctly), it completely missed to identify the source of the ontological problems with non-relativistic quantum mechanics.

  11890. The Inquisition didn't exist for Newton as a real threat, but he would have certainly lost his position and livelihood. Spinoza was certainly under a more severe threat still. Exactly right.

  11891. You can see this in a spacetime (Minkovski) diagram if you wish. The principle of relativity says (among other things) that all observers are equally competent and that their observations have to be treated as equally valid. For spacelike separated events (that are not in causal contact), we can find observers which will observe A before B and others which will observe B before A. And somewhere between those two is an observer for whom A and B seem to be happening at the same time. What all of these observers can agree on is that there can be no causal contact between A and B. Nature could have chosen a cacophony of causal dependences, but it didn't. It implements exactly three classes of causal relationships that are roughly (A may cause B), (B may cause A) and (neither can cause the other). On a slightly deeper level this destroys any notion of simultaneity in different locations. See the "Andromeda Paradox" and the "Rietdijk–Putnam argument". Personally I find the lack of simultaneity the hardest to "grok", but that's probably a personal shortcoming of my intuition.
    1
  11892. No, it doesn't. Ukraine's future mostly depends on its leadership. They need to keep playing one of the smartest military stratagems on the battlefield that has ever been played. They have very few spare resources to cover for serious mistakes. If the fail to balance their resources correctly, Russia will either break through (less likely) or manage to freeze the war (more likely). They can't allow either to happen and so far they haven't.

  11901. They tried that. Neural networks seem to make actually pretty good educated guesses, at least statistically speaking. It doesn't solve the predictability problem (that's mathematically impossible) but it might lead to numerical techniques that are more powerful than the conventional brute force algorithms.
    1
  11902. Many people struggle with subtle concepts. I remember some kids in my high school physics classes who were absolutely out of touch with the material. They weren't even the least performing kids. Some were quite artistic. Some, of course, become obsessed with "proving physics wrong".
    1
  11903.  @davidhand9721  Yes, then there are the folks who want to prove Einstein wrong... Coming back to school, I remember one girl nearly started crying because she couldn't understand harmonic motion. It was one of the few times that I thought that we are teaching high school poorly. Or maybe there really are such large differences between individual people's brain structure that they can't be overcome even by refined teaching methods. There is, for sure, a real problem here as society becomes ever more dependent on ever more complex science.

  11904. Because if you can have everything, then you have nothing.

  11910. Yes, you are missing that kids are perfect vectors for the disease. They may not die themselves but their grandparents and strangers might.

  11911.  @MrWhisperingwildly  Vaccination? It stops people from becoming vectors, so it stops the infection of others. We taught you that in middle school. Why did you not listen? :-)

  11912. String theory is simply one solution of relativity. That solution exists as a mathematical fact, whether nature cares about implementing it or not.
    1
  11913. That sounds really scary, until you look up the real world data. The power consumption of the UK is falling. Efficiency gains are making the supply problem easier, not harder. If necessary, you can install local peaker plants, which will take care of the problem.

  11914. That's what the Trumpians will say anyway. The reality is that none of the investment in AI will bear fruit. People aren't willing to pay for AI any more than they are paying for search, right now.

  11915. It's the sin of having bad parents. Unlike many others that's a real sin and a total downer. It's nearly impossible to escape. Even if you survive your childhood experience (which many of these children will not, as you can see), the bad decisions of your parents will always stay with you. Sometimes not even a lifetime of mental health treatments and atonement will be enough to overcome bad parents.
    1
  11916. Fact 1: university is NOT primary school. Professors are not there to help strugglers. They are there to teach the most to the best. Fact 2: CS is not about programming or system administration or any of the typical job description items. It's the theory of information processing systems. Programming is merely a tool.... but if you can't learn the tools, or you don't want to, how are you going to get the job done?

  11917. So that makes hostage taking OK, then. Dude... can you even hear yourself?

  11919. Why would you be surprised about not having sufficient antibody count? If it can't be detected by multiple consecutive tests, then your body simply doesn't make enough. Nature didn't give you a guarantee that you were born with a perfect immune system. You may just be one of those people we call "immunocompromised" and you may have to live with that. Duh!
    1
  11920.  @nessierose7652  And, yet, you don't have antibodies. And that is not the only thing you are obviously missing, kid. :-)

    1
  11923.  @chucksalvo2944  Where did you get the nonsense from that hidden variables have to be random? :-)
    1
  11924. It's a bit complicated. The transmission line formed by the wires has an impedance of between 100 and 200 Ohm, the bulb has an impedance of roughly 1 Ohm, so the signal that propagates near the speed of light along the transmission line won't do much to light up the bulb. Replace it with a 100Ohm resistor and you got yourself a cable pulser. The resistance of the copper in the wires and the skin effect cause an exponential loss with length, so the last 299,990 km of the wire loop do not even matter. There will be no DC current left to light the bulb. :-)
    1
  11925. You are correct. You don't have to get vaccinated. You can just do it like my eight anti-vaxxer relatives and get COVID-19 a second time. You can be sick a second time and be an effective vector for a second time. Why not? It's a lot of fun and makes you an outstanding citizen. ;-)

    1
  11930. Also 100% false. ;-)
    1
  11931. That's incorrect. We have many different versions of quantized gravity, they just don't predict anything actionable. What that tells you is that gravity is, most likely, not the Rosetta stone of physics. That spacetime fluctuates randomly is trivially false, by the way (this follows from very basic insights like the fluctuation-dissipation theorem). It's also ruled out by local conservation laws. We can MODEL spacetime TO FIRST ORDER with fluctuations. Whether that is successful or not depends on the phase diagram of the system and how close we are to phase transitions and critical points (hopefully not very close because a phase transition of spacetime would kill us all instantly). Again, this is conceptually old stuff... it was developed in the 1960s or 1970s, I believe, on thermodynamic systems. People just think they are inventing something new because they haven't seen it in other contexts. That doesn't mean it's conceptually actually "new".
    1
  11932. That's standard quantum mechanics. We had initial and final state since Heisenberg wrote his matrix mechanics papers. It's even more obvious in those papers than in the standard formulation of Schroedinger and von Neumann why that has to be so. It does not take care of the measurement system dependence of the outcome. Nothing can because that is a real physical effect. The uncertain nature of individual quantum measurements is a direct consequence of relativity, so nothing can change that, either.

  11933. You are correct. Enters Trump. ;-)

  11942. MAGA exists because of an aging population of people who think they didn't get "their share" of the US economy. I spoke to some of them. There isn't much more behind it than childish "revenge for perceived wrongs". If they can't be happy, then they don't want anybody else to be happy, either. Old people have a limited lifetime. The phenomenon will go away, eventually. The question is how much more damage it will cause.

  11948. I have seen talks in the 1990s by atomic physicists working on chaos in Rydberg atoms in strong magnetic fields where they were showing fractal spectra. I think there is mostly a disconnect between the atomic physics and the quantum mechanics foundation folks going on there. The foundations people haven't been reading the already existing experimental literature enough. If anything, to me this seems like a rather old hat.

    1
  11961.  @kornaros96  Even with LEDs. If you have slightly older bulbs, then they are wasting 50% if the energy. The best ones you can buy are still losing around 25%. Your real problems, however, are your HVAC system and your car.

If you can't come up with a better way to save the world than keeping an old phone 2 years longer, then you are simply completely ignorant about how much damage you are really doing.

    1
  11977.  @nottieru  Electromagnetic waves are made from many quanta. I can measure them over and over again. I can only measure one quantum once. That's the definition of quantum. The physical difference is not rocket science. It's the same as the "Sesame Street" lesson about the difference between "One cookie and many cookies" with Ernie and cookie monster. It's on YouTube. :-)

  11982. Quantum mechanics and probability theory can be derived from the exact same axioms and they describe the exact same kind of lack of knowledge. Mathematically quantum mechanics is a multi-dimensional theory of the partition of one, while probability theory is a one dimensional version. The physical difference is due to relativity. In classical mechanics the lack of knowledge is caused by "willful ignorance", i.e. we just don't measure a pre-existing state precisely enough. In quantum mechanics, however, there is no such state to begin with. Nature simply does not know what the next measurement outcome will be. This is caused by relativity and it is a fundamental barrier to knowledge.

  11983. Anybody can build a cheap car in China. The inferiority of the Chinese car industry is demonstrated by the fact that they are not even trying to build a cheap car in Europe or the US (which would get them around tariffs). They know that they would fail to be profitable.

  11984. Desperation doesn't get you hired anywhere, except maybe by local organized crime. To an employer a four year degree means that you have demonstrated that you can stick to something stressful (school) for four years (and not just mere days) without being forced. If you don't understand that then your are just not very smart when it comes to real-life matters.
    1
  11985.  @adrianlatham7462  I am telling everybody the same thing. Higher education is part of growing up. It's not a waste of time. It gives you the opportunity to grow in ways that you can't on the job. This delusion that K-12 plus three days of classes are enough to perform a complex job is simply a conjob that prays on the desperate. Even in the deep past (as in antiquity and the Middle Ages) unpaid(!) apprenticeships lasted for many years. Journeymen would then often go from master to master and workshop to workshop for years to acquire the best techniques of their time and to find a place where there was enough work to be had so that they could settle down and eventually open their own master workshops. With regards to passion... Dude... it took me 12 years to become a physics PhD. The problem I had to solve in my thesis took me over three years. A person who talks about days spent on a detail, to me, is basically just a professional quitter. ;-)

  12023. Yes and no. Part of the problem is Germany, which is restricted in its military (it can, for instance, not have nuclear weapons and long range weapons, if I am not mistaken) by its history and its post WW II peace treaty. It was not supposed to be sufficiently armed and as a result it isn't.

    1
  12036. ​ @LateNightRadioe  We can agree about all of that. To address your question... do I believe that one can find an algorithm to stop people from hating and doing nasty things to each other? No. Historically mankind has always tried to implement such systems in form of laws and religions and, foolishly, even in the hope that the rule of the one just king (emperor, chancellor, party leader etc.) would set things right. Any and all attempts proved futile, even though some produced short term and sometimes lasting net positive results. Facebook is, on that scale, a rather tiny blip of a phenomenon. I can even tell you that I do not believe that American Democracy is on the brink because of Facebook or the internet in general. These are just lame excuses. A significant part of the American electorate is merely falling into the same trap as the good German people who cheered for Hitler before the war. They believe that a strong man (it never seems to be a strong woman) can magically make all their discomfort with reality disappear. That discomfort is real, it is not imagined, it won't go away magically and no strong man can make it go away, either. No algorithm can heal it, no amount of "discussion" on the internet can reduce it. We all have an itch that we can not scratch. It's called being human, it's called being mortal, it's called being lonely, it's called being poor and there are many, many more such limitations that we can't overcome because of the biology of our species. Having said all of that, communication has become a tool of mass destruction. If we don't want to destroy ourselves, then we will have to regulate it and that is a discussion that has to happen on a much larger scale than that about the algorithms of internet advertising companies.

  12049. I only have one data point, but the antivaxxer branch of my family (eight adults, two young children) contracted COVID-19 in mid-2020 and now about 18 months later, they all contracted COVID-19, again. None of the vaccinated members of the family (ten adults) got infected at any time. It seems highly implausible to me that previous COVID-infections give any useful protection against re-infection on the 18 months time scale, but proper social distancing, mask wearing and vaccination with recent booster still seem to be highly effective.
    1
  12050.  @nickbarnes4303  We even know where they acquired the infections. The first time it was a party attended by a young male family member. The second time it was a weekend trip to a hotel by one of the older adult couples. The problem is not "just" vaccination status but socio-economically driven behavior. Their response to COVID-19 has always been "we are in god's hands", which indicates that they simply do not take it seriously (the running joke in the remainder of the family is now that "god gave it out with both hands", of course). I feel like I am looking at a small laboratory version of the population within my own family. The virus seems to have an enormous reproductive advantage among people who think that this is a joke.

In Eastern European countries that were using the Chinese vaccine the numbers are horrible.

  12094.  @berryboi1574  You do have a point, of course, that in the US education has been left to the vultures and rent-seekers. The ideal combination for a person is to get a degree in a country with free higher education and to move to the US to make money. That brain drain is, among other things (like the lack of capital for investments and a risk oriented investment culture), a major force why economically smaller countries are at a technological disadvantage. This process has been going on for a long time. We need to reverse it to bring the entire world to the same level of development. In my opinion Northern Africa can be a very valuable extension of the European economic zone and historically it has been. It was the main grain producer for the Roman Empire, after all. Its fall had a lot do with the loss of its main food sources. Today all of Africa, including the Maghreb countries, are the main untapped source of worldwide human potential. It is young, it is hungry (for knowledge, thankfully a little less for food these days). It has natural resources, not just in form of minerals and beauty (for tourism), but also renewable energy, that could power Europe easily. Instead of the desperate exodus of Africa's poor who will trade the squalor of European immigration camps (at the ultimate risk of their lives) for the instability of their home countries, it's time to make Africa an attractive place to be. Let Northern Africa, in particular, return to its former glory, as the supplier of Europe's lifeblood.

You don't have to believe all the nonsense that uneducated people make up to fill their empty lives with. We did, by the way, tell you in high school what a measurement is: it's an irreversible energy transfer. We didn't use the word "irreversible" because that's more undergrad level physics, and we didn't tell you that the definition of a "photon" as a "quantum of energy" can be generalized, but that's all extremely trivial stuff. It's basically just preliminary definitions to get you started with real physics. There are no problems and questions here. There are only people who don't even know the basic definitions.

For thermal storage molten salt, concrete and different kinds of rocks like basalt and granite are feasible. We could literally use old construction debris as heat storage medium.

An average Bundeswehr kid fired less than 500 shots in his entire military career, of which half were blue plastic training bullets. They didn't have money for more ammunition. :-) On the other hand I have seen three US soldiers at a shooting range bang a machine gun barrel to death all day long, emptying one crate of ammo after another. I went there to ask them what they were doing while the poor gun was cooling down. They said they had too much old ammo and that by regulation it had to be disposed of in an active training exercise. Now that was some good shootin'. :-)

  12136. Putin has been very careful not to escalate to the point where a direct military involvement of the US becomes inevitable. The Russians talk a lot but on average they are acting conservatively. Ukraine also hasn't played its biggest hands, yet. They have clearly demonstrated that they can take out most of Russia's refining capacity, if necessary. That was probably as much a shot to the bow of the US than it was one to Russia. Destroying Russia's critical infrastructure right now is not the best of ideas, but if there has been no change in the US support by winter then Ukraine will try to bring Russia's transportation infrastructure to a grinding halt during the winter months. It's unlikely that Russia has the air defense capacity left to prevent that. If the Ukrainians are preparing thousands of long range autonomous drones for such an attack (and why would they not?), then it will shut down the country for good. It doesn't take a nuclear attack. A conventional attack with toy planes will be enough. I think the US needs to be very aware of the consequences of that and help Ukraine to win this conflict without such an escalation.

It wasn't actually cool back then, either, but nobody could have explained reality to those kids and nobody even cared to try. I certainly won't try now. It's a waste of time.

I can't think of anybody in the Arab world who is not on Israel's side right now... they know that if Israel can't control the Palestinians, then it will push all of these people into Egypt and the other bordering nations. Absolutely nobody in the Arab world wants these people in their countries.

  12200. OOP languages aren't passing either objects or values around. They are passing pointers to objects around. Your C compiler already does that when you tell it to pass an array or struct. That is, in essence, a message about a data structure's location. If you want, then you can define a function that passes pointers to structures (nouns) and and functions (verbs) and if you want, you can give it adjectives and adverbs (decorators in modern language, if I am not mistaken), and you can do that in any language that can pass more than one variable into a function. One should not mistake OOP syntax (which is entirely for the sake of program documentation) with actual compiler implementation of that syntax.
    1
  12201.  @reinux  If the message says "perform algorithm X on data Y" (and that is what it usually says), then this is twelve of one and a dozen of another. I have rarely seen problems that stay at a higher level of abstraction than that for long. How we express that in our language is more or less just a question of syntactic sugar.

  12206.  @sebbbi2  The fluctuation-dissipation theorem predicts that random fluctuations are inevitably linked to dissipation. Quantum mechanical systems are not dissipative. That's the end of randomness. That the opposite of randomness is NOT determinism is something you will have to work out for yourself. You are simply suffering from false dichotomitis.

  12207. Neither problems exists in reality. Physicists are making trillions of quantum measurements every day and there is NEVER a problem, neither big or small. ;-)

  12208.  @wmstuckey  I love Mermin but he is talking total nonsense there. While he is trying to say something of importance (and his conclusion is correct), the language that he uses contains a lot of technical errors. First of all none of this is statistical in nature. Instead we are dealing with different levels of uncertainty (i.e. lack of information), including lack of information about the future! The measurement process itself switches from an isolated to a non-isolated system and while the former is reversible, the latter is completely irreversible. That the measurement process can not be described with unitary dynamics is a trivial consequence of the fact that it breaks unitarity. The system in our unitary dynamics description simply seizes to exist during the measurement. Sometimes theorists are showing a kind of ignorance of the consequences of the "systems" definition in physics.

  12213. That is actually a very good question. Why is the evaporation process not symmetric? On a fundamental level it's not symmetric because most of the evaporation is very, very close to thermal equilibrium, while the collapse process is extremely far from it. In practice it black hole with the mass of a couple of solar masses (which would be the necessary mass of a neutron star) is completely quiet. It has a luminosity of 1e-30W or something on that order. I can't think of any macroscopic systems that have such a low electromagnetic emission power. Maybe something like an extremely long lived nucleus gets close... if we average the energy flux out over the lifetime.

  12216. Does the probability distribution of a dice collapse when you throw it? Why not? If it doesn't, why should a wave function collapse? It's ontologically the same thing as a probability distribution.
    1
  12217.  @Pengochan  I don't know where this idea comes from that the wave function is the state of the system. If it were the state of the system, then it could make more than just ensemble predictions. In reality a wave function can't predict much at all for a single experiment.
    1
  12218.  @Pengochan  The wave function does not match the single experiment at all. It only matches an infinite repetition of experiments. You are confusing yourself. A single photon makes only one dot on a screen. A single dot is not an interference pattern. This is a typical example of people not seeing the trees through the forest. It is really simple: one is one. A single photon is a single photon. As soon as you are talking about "interference pattern", you are talking about an ensemble. You really need to pay attention to the language that you use and what it actually means in reality. I have never seen a particle. Neither have you. We have observed quanta, but they only occur at the interface of a quantum field and an irreversible system. They can not be found empirically anywhere else. It is not good to assume the existence of physical properties where they have never been observed. That's religious/magical thinking, not physics.
    1
  12219.  @Pengochan  Yes, you get interference in an ensemble. That's what wave functions describe. There is no interference in single quantum experiments and there are no physical descriptions of single quantum experiments. That's the first two minutes of QM 101. What, exactly, is your issue with these facts of nature? I have seen a coronavirus. There are plenty of electron microscopic images of them online. At that point I stopped reading because you stopped making sense.
    1
  12220.  @Pengochan  I am an experimentalist in the field of high energy physics. I have never seen a particle detector. I have only seen and built detectors for quanta. Now, you may not know why quanta seem to behave like particles under weak measurement conditions. That's your problem, though, and it can be easily remedied by reading Mott's 1929 paper titled "The wave mechanics of alpha-ray tracks". Happy reading! You also need to learn to count. A single quantum experiment produces exactly one measurement. It can never produce destructive interference.
    1
  12221.  @Pengochan  Now you got it. There are no tracks or any other "particle properties" until weak measurements are being made. That is exactly the mechanism by which "classical physics" emerges from quantum mechanics. It is amazing that this is still not being taught much in QM 101 classes. I did, by the way, find an article by Heisenberg from 1927 where he suggests exactly that mechanism and he sketches it out for the example of Rydberg atoms. So we can be sure that even the founders of quantum mechanics had this more or less "in the bag", at least intuitively. Why the internet is still speculating about this triviality is the only mystery here.
    1
  12222.  @Pengochan  For a single copy? There is no description for a single copy. We can't predict the outcome of a single experiment. The wave function is the description for an infinite ensemble of copies. It's no different from dice. I don't know what the next outcome will be when I make a throw. It could be 3, it could be 1 or any other number. All I know is that if I make enough throws, then on average all outcomes are equally likely for good dice.
    1
  12223. ​ @Pengochan  An ensemble is just a large number of identical repeats. The wave function is the physical description of the ensemble. Even when you say "one could have an ion with spin 1/2 prepared" you need to be careful what you mean. Do you mean you have ONE ion prepared into a certain spin state or do you mean that you have a pure spin up state of an ensemble of ions prepared? Most people mean the latter. If I do exactly one measurement on one member of a mixed state ensemble, then I can't even tell that it's a mixed state ensemble. I will always get an individual pure state as the answer, I just don't know a-priori what the answer will be.

  12228. Wow, that gets the price for being the most stupid interview in the history of the internet. The industrial revolution got already started in Rome and Greece before the advent of Christianity, it simply got stopped by economic collapse after the third or fourth century AD. The Greek and the Romans were very much into machines like water driven grain mills (and so were Medieval people, by the way, they just couldn't afford all that many of them) and they would not have been able to prosper without a significant level of automation and mass manufacturing techniques.
    1
  12229. That's because states can not control the money supply and they operate under different economic rules than the federal government. They also have very different responsibilities that exclude major line items like social security, defense and R&D. States do not pay for most of the technical innovation that happens in this country, even though they greatly profit from it. That line item alone represents the entire GDP of a small country like Hungary. Not everything is like home economics and the federal government can simply not go broke.

  12241. I do understand your sentiment on some level, but let me remind you what happened the last time Germany was a "leading" nation. That didn't go so well for Europe and Germany TWICE. As a consequence the German government has been preaching "Friede, Freude, Eierkuchen" (peace, joy, egg cake) to multiple generations of German students in public schools. That educational campaign actually worked really well. So, yes, now you have a VERY peace loving nation in the center of Europe that will be extremely hard to convince that it should be sending its soldiers into another war with Russia. You may also have noticed that the immigration question has been driving German right wing nationalists (aka Nazis) to the polls lately. The problem with right wing German nationalists is that they don't see right wing Swedish nationalists like yourself as equals. They may see you as a means to an end, just like they saw right win Italian nationalist in WW II as canon fodder, but that's as much as you can hope for. To these people you are still an Untermensch, no matter how much you may think otherwise. So, yeah, I would not advise Europe to wake den Deutschen Drachen. Nothing good will come from it.

I could never do that with vi. OK, now you got your two minutes of attention. I hope your basement has gotten a little warmer. ;-)

  12276.  @polblanes  You can't teach a student who can't even deal with differentiation rules for functions of a single variable something like topological algebra. Neither can you teach everybody how to play Chopin. Humans don't work that way.

  12277.  @polblanes  Dude, I consistently got As on all my math tests in high school. I consistently failed in mathematics in university. It's just not the same thing, OK? What we are teaching in K-12 is to real mathematics like painting walls is to Michelangelo and Picasso. No resemblance. So if all you want is to get K-12 students to remember a few calculus formulas for the next two hours while we are administering a test, then, yes, we can do better memory games with them by adapting to their pace, but that doesn't mean that they will actually learn math.
    1
  12278.  @polblanes  Yes, Dude. I had all the motivation in the world. I am a physics PhD. I can do experimental physics (and have) at the professional level all day long but I can, for the life of me, not prove a few trivial theorems from calculus and geometry. My brain just doesn't work that way. Guess what else I can't do? I will never be quarterback in an NFL game. I will never play Chopin in front of an audience at Royal Albert Hall. I will never compete in a Formula 1 race. I will never fly to the moon as the pilot of a spacecraft and I will never, ever, rescue someone from a burning building. And neither will you do any of these things and the next best kid won't, either. Some things can only be done by people who have the right brain structures for them. What about that offends you? ;-)

  12291. All true and utterly irrelevant. If the best functional programmers in the world write a completely error free program in the best possible way and leave it to a team of average programmers for maintenance, the only thing those people can do is to write it from scratch immediately because they won't be able to read it and they won't be able to extract the logic behind it. FP is like Sanskrit, it's great for those who can read it (maybe) and to everybody else it's completely useless.

    1
  12301.  @immanuelkant7895  "Dark matter" is the name of the observation that there is excess gravity in galaxies and other large scale structures of the universe. That's the effect. "Dark matter particles" is the name of the hypothetical optically non-interacting matter that dark matter (the phenomenon) is caused by. That's one possible cause. You would have been correct if you had said that no telescope has ever observed dark matter particles. Yes, I know, physicists are pedantic... that's part of the success behind physics. We differentiate between cause and effect. And, yes, you are also correct, some of the naming of phenomena/hypotheses etc. is between questionable and idiotic. Like string theory is not a theory. And particles are actually quanta. And so on and so on... :-)
    1
  12302.  @immanuelkant7895 The proposed hypotheses are "dark matter particles" and "modified Newtonian gravity" among a few other things (like a mix of both). Galactic rotation curves are just part of the evidence that makes up the dark matter phenomenon. Like I said, the naming of "stuff" in science is not always a winner. Just look at how the astronomers have messed up the term "planet" recently. Does that look rational to you?

  12317. Penrose is senile. Kaku sometimes talks complete nonsense, but not always. Everybody in physics knows what string theory is and is not. We don't change established terms just because the public is too lazy to learn what they mean. String theory is also not a hypothesis. You can call it a branch of mathematics, if you want, or a model in physics. Nature may or may not implement this model, but that doesn't make the mathematics of it false.

It's not fundamentally different from the double slit and that's not even a quantum experiment (and neither is this).

    1
  12346.  @JackCollins-r4r  Those are all counted in the corporate numbers. Technically a lender does own your property if you haven't paid back most of your loan, yet, but that doesn't count because they will not evict you as long as you are paying. They can't raise rent on you, either. Seriously, the problem here are NOT the corporations. The problem are the boomers. What we are seeing right now is a giant wealth transfer from the young to the old. The tragedy is that it doesn't make most of the elderly rich, either, because it is not on a one-by-one basis. It's just the result of an aging population where the elderly are outnumbering the young. The US could solve all of this with immigration and by building low cost housing, but it is again the egotism of the elderly which prevents both solutions. You will simply have to wait for the boomers and their offspring to disappear the natural way and then housing will become cheap, again. That is going to happen towards the end of the 21st century.

There is no functioning country in the world that does not monitor the movement of its citizens across the border for a variety of purposes in one way or another. The EU has the Schengen accord where they have lifted that requirement within EU borders, but that's entirely internal. Any travel outside of EU territory is still subject to exactly the same requirements as anywhere else. If you actually move in the EU between EU countries, i.e. you change your place of living, then you still have to un-register and re-register with the local authorities. Non-compliance has severe economic and legal consequences, even within the EU. So, please, stop talking bullshit.

Those are the only user groups who can be excused for believing every bit of bullshit they see on the internet. The little ones are still naive, the old ones already have dementia. Everybody else is required to check everything against textbooks and the primary literature. ;-) Grant's channel description that claims "physics is adjacent to math" should already have given you the chills. Physics has absolutely nothing to do with math (except that it's the foundation of math and that it abuses its notation). Some mathematicians are completely oblivious to what physicists really mean when they use the equivalence sign. :-)
    1
  12362.  @Harrykesh630  Physics uses the language of math but it means something entirely different with it. In F=ma the mathematicians only see three variable (or two variables and a constant). Physicists see three completely different phenomena: acceleration, inertia and force. The equation defines how we measure force through acceleration and inertia or how we can measure inertia through acceleration and force or how we can measure acceleration through force and inertia. You can't get that out of the mathematical equation, at all. That's knowledge about the world that is entirely external to the mathematical symbols. Grant's channel is fine, as long as he sticks to things he actually knows, which is math. Physics is not math. It's much more than that. It's millions, if not billions of actual experiences about the world.

  12363. It can be explained in less than one minute. Time is that which the clocks show. Clocks are local energy reservoirs that disperse this energy evenly towards infinite. In order for clocks to run backwards some physical mechanism would have to collect all that energy back into the clock. Such a mechanism doesn't exist. End of story. :-)

  12374. Not really. It's two years later and none of these models has grown exponentially in their ability to solve problems. They are all still struggling with elementary school questions and are disintegrating on absolutely trivial problems that they simply haven't seen before. The more likely outcome here is this: ten years from now even the best AI of this kind will still be at the level of reasoning of a first grader (or below) and hundreds of billions of dollars will have been spent on a technological dead end. Would you like some VR with that? That's a much, much easier problem, by the way, but the results of 2023 are not substantially better than the results of 2013 were.

  12378. Measurements are either independent and then the usual formulas of quantum mechanics apply or they are not independent and then these formulas do not apply. One can find plenty of case of both kinds in nature. We simply do not discuss the math required to deal with the non-independent cases much because it leads to a lot of ugliness that the independent case manages to avoid.
    1
  12379. @ Independence means that one can not predict the next quantum using the previous n quanta. Radioactive sources are considered independent. The light of a laser OTHO is highly correlated and so consecutive measurements are not independent unless we wait for a long enough time between measurements. For independent measurements we can replace the physics of the actual physical source (ONE physical source!) with an (abstract!) ensemble of that source (the ensemble contains an infinite number of exact copies of the actual physical source). Quantum mechanics is an ensemble theory. One of its assumptions is that we can make that implicit replacement and so we do not have to think at all about the physics of the source. We also don't have to think about the physics of the detector any longer because unlike real detectors that have e.g. deadtimes, the ideal detector is exactly the same every time. Needless to say, only theorists have this luxury. Experimentalists are thinking about statistical dependence in sources and bunching, saturation, after pulses and other memory effects in detectors all the time. We don't have the luxury of the idealizations that the theorists are working with. ;-) So, yeah, anybody who thinks that physicists are not 100% aware of the problem is full of crap because they have never worked in an actual physics lab. ;-)

  12386. CPUs are currently faster than their bus systems, so the CPU will usually be waiting for IO. The much bigger concern are cache misses, though. Those are enormously expensive. Having said that... what kind of applications do you have at home that require 10GByte/s or higher IO speeds? Are you serving the entire neighborhood with 4k tv? How does your ISP feel about that? ;-) Databases on hard drives are slow like frell, anyway. You don't need a fast computer to wait 5ms for the disk to turn a full revolution. I am not aware of applications outside of internet search that have a fast DB problem, anyway. An average bank client makes a dozen, maybe a few hundred queries a month. Even if you have a bank with 100 million clients, the total transaction volume is limited to maybe a billion queries a day, which is in the range of 10,000 queries per second. I can write a Python script that can do that on my ten year old laptop, assuming that the database keys can be held in memory.

It's a continuously operating scientific branch that has the exact same goal (measuring the spectrum of the physical vacuum) that it had in the 1940s. You need to get an education and stop believing all the bullshit on the internet.

  12395. State can not be reduced. State is that which the program has to modify to do something useful. The problem of software engineering is to define the state space of a program properly and to prevent it from modifying its state in an uncontrolled manner. FP does not thing to address either concern. OO is mostly in the way of rational software engineering strategies that handle state safely because it makes it very hard to modify state consistently if the requirements change and the class hierarchy does not reflect the requirements any longer.
    1
  12396.  @tiansivive  What you are describing is programming with kiddie safety wheels. If you don't even trust yourself with the atomism of an array arithmetic function, then you are nowhere close to the level of an actual software engineer. Not that FP would help you in an environment in which you need re-entrant functions that are being called from inside multiple asynchronous hardware interrupts... which is exactly what one of my programs has to provide. I have a hardware product out there (selling for the better part of 20 years now) that has zero known bugs and 100% uptime that is entirely written using global variables for state. That was a deliberate design choice. The solution to this mix of hard real-time and unsafe parallel operations was a custom round-robin scheduler that has full visibility of EVERY system variable. Because it knows the full state of the system (there aren't ANY local variables!) it can always decide what not to do. It doesn't do unsafe operations immediately but instead puts them in a circular call buffer. Only after all functions that could possibly interfere with each other have been cleared can the system perform certain "unsafe" operations. That worked like a charm... ;-)

  12397. Quantum mechanics is perfectly local. Why are you telling us that you didn't read the textbooks? They usually say this in the first chapter. :-)
    1
  12398.  @Bolidoo  "Locally real" is not a physical term. It's philosophical nonsense. That there can be no hidden variables follows directly from relativity. There is no need to even think about this for as long as three seconds. You can see this in every spacetime diagram if you know where to look. Quantum mechanics is local because of relativity. If it were otherwise, we would all have ansibles in our cell phones. On the downside the universe would not exist, of course. ;-) Determinism never existed. It's an 18th and 19th century phantasy like the phlogiston and the aether. Also not worth discussing from an empirical standpoint.

  12399. Why are you telling us that you don't understand physics? ;-)
    1
  12400.  @coloradoing9172  Thermal randomness probably does apply, though, but it is not the reason for "free will". The reason for that is that the future is truly not determined by nature. There is no function that could be applied to the past that can predict the future state of the universe. Hard determinism as envisioned by 18th and 19th century thinkers simply doesn't exist. Nature can locally "change its fate". It can do so at the level of simply physical systems (like a nuclear decay) and it can do so at the level of human decision making.

  12409. Yes, but that is not what Sabine is saying. She is telling everybody to stop the presses completely, including experiments to "rethink" what we are doing. That's not how it works. We are "rethinking" what we are doing every day eighteen times. It just so happens that "rethinking" doesn't get you new data in experimental physics. Only a bigger machine gets you new data. She knows this. Anybody who believes that she is just naive is naive themselves. Sabine is a person with a serious narcissistic personality who only thrives on one thing: the manipulation of people. She has no interest in physics whatsoever.

  12424. Stepping up the public education system won't help. All you are creating that way are even more students who will fail in school and who will hate everything intellectual. Imagine being called a loser for 12 years in a row. That leaves a mark and a distaste for everything related to learning. So what's the solution? There isn't one. We can simply not run democracies with the person of average (i.e. insufficient) intelligence. We will either have to wait for a genetic or technological brain update (human 2.0) or we will have to get used to totalitarian governments all over the world (which will probably lead to a nuclear war in the end and a reboot of human civilization).

  12428.  @eromod  First of all, you aren't being owed respect. You have to earn it. Please grow up. I am also serious about telling you that you are clueless about science. It doesn't need assumptions. All it needs it gets from nature in form of empirical evidence. That includes all the fundamentals. Science is not creative writing. It's the rational description of nature. Unless you find Adam and Eve's graves it's not science. That's the end of that bullshit.

  12444.  @robertstimmel1100  Sorry to hear that. My Mom was waitressing for many years to get me trough school. Today her knees and back are shot. That's why I keep telling people to get out of that dead-end job. Having said that, you obviously made way more than she did in those low end eateries that she had access to most of the time. She made good money once, working at a Hilton for a year, but then we had to move. I hope your job change will work out. I am just fairly negative about the software business in general. It has been drifting towards the low end of the technology job scale as software went from a high tech and luxury item to a commodity. I don't see that development slowing down. Companies are asking ever more output from their staff, some well beyond the human breaking point, it seems. That's not a healthy development. Fifty years ago programming was a dream job (maybe), today, not so much.

  12451. There are no objects in quantum mechanics. There are only systems. In non-relativistic quantum mechanics the observer (better "the detector") is a system. In relativistic field theory even that has been eliminated and replaced with much more simple asymptotic states.

You won't be able to understand quantum mechanics until you fully understand the meaning of that sentence. Dude, quantum mechanics can be fully understood at the high school science level. It is NOT difficult conceptually, but you have to pay attention to the details. That's just a general requirement in science. :-)

  12475. Galileo found more than that. He gave a correct example of the relativity principle. It's called Galileo's ship and basically represents the non-gravitational equivalent of Newton's elevator. In a sense Galileo may have discovered the theory of everything around 1630 with that. He just couldn't calculate the logical consequences of his discovery. That would take close to another 400 years. If I had to hand the price for most important physicist in history, I would probably give it to Galileo rather than Newton or Einstein. Having said that, Kepler and Copernicus may have known about the relativity principle already before Galileo and I have a strong feeling that one may find hints of it in the writings of antiquity. Galileo probably just formulated something that had been floating around more succinctly.
    1
  12476. Quantum mechanics can't give you "anything more" because its complete. The structure of the theory is completely determined by relativity. So if relativity holds, then quantum mechanics is what it is. General relativity holds because of the equivalence principle. We would have to observe a true violation of that. If dark matter were to couple differently then the metric approach would be dead, for instance. Maybe one should take that seriously and explore that option theoretically.

Only Congress can overturn the decision of a case officer and that rarely happens. At that point the couple could chose between staying in the US, which made the wife illegal and moving to her county where a similar process would have happened. The only other alternative would have been to ask for political asylum in a third country. I am not aware of any country that accepts "love despite denied visa" as grounds for political asylum. Rich people can solve this problem easily with money, by the way, simply by traveling twice a year or the wife could have invested a million dollars in a US business with ten employees. This is exclusively a problem of the "not rich enough".

  12515.  @dare2scheme904  There is no appeals process in these cases. You get rejected, you get rejected. It's not a judicial system. There are no juries. There is zero protection by the US constitution because you are not a US citizen. It's just bureaucrats making decisions based on... whatever. You are not even being told why you are being rejected. I had a colleague who went through that and who had to return to Russia. This doesn't even have to happen in Washington or wherever the usual case officers work. In certain cases a customs officer at an airport can handle your case and send you back from where you came from. That, too, happened to someone I know. He even had a valid green card at the time. The officer just looked at it and said that he wasn't welcome in the US any longer. The green card was gone and he was on the plane back to China. End of story. No appeals process, whatsoever.

  12516.  @dare2scheme904  They didn't get denied. So what? So nothing. Neither did I and dozens of people I know. There is no problem until you get denied. Once you do, THEN there is a huge problem. Tell you what. Live ten years as an asylum seeker like I did (not in the US, though), then we talk. I have been there. It's not nice. Also completely unnecessary. This country needs five to ten times more immigrants than we let in legally just to keep the lights on.

It does not have to explain things that have never been observed. That's NOT theory. That's speculation. Until somebody sees quantum gravity effects the entire graviton concept is just intellectual nonsense.
    1
  12525.  @Paul-li9hq Yes, you are wasting your time because I am a physicist and from my point of view you are simply talking nonsense, my friend. Neither your home schooled use of the word "theory" nor your desperate need for attention impress me much. That you have never read a theory book about gravity is obvious. I would lend you my 1250 page copy of Misner, Thorne, Wheeler "Gravity", but what would you use it for? As a doorstop? ;-)

  12527. Huh? Russia hasn't developed any new civilian rocket technology in ages. There is nothing there to "want". Elon Musk is suffering from a number of mental problems, some developmental, some personality disorders. He used to be a very high functioning business man (that's in the past since his Twitter acquisition) and we will see how well he still functions as a technologist after SpaceX launches Starship, again, and after the release of the Cybertruck by Tesla. Tesla's lack of innovation in recent years makes me wonder of anybody is still controlling that "vehicle". It seems to be on Autopilot these days (pun!) and might very well run into a standing object these days. Organizations are like that... they function just fine even years after they literally lose their heads... and then they just collapse.

  12543.  @janbielecki94  I don't disagree with anything. All I said is that we tried emergent gravity and it doesn't seem to work well. I already noticed as a third year student that general relativity looks like a thermodynamics system. So what? So has probably almost everybody who doesn't have a cauliflower as a brains and who took a GR class and a thermodynamics class in the same year. But noticing that the equations look similar and then making a new theory out of them is the difference between a mediocre physicist and a genius. Using the words "emergent gravity" doesn't make you a genius any more than noticing that the equations have the form of thermodynamics differentials makes one out of me. Plenty of theorists have gone down that rabbit hole and they came out soiled... because that's what is in most rabbit holes: crap. :-)

  12549. I don't know how old you are, but I can assure you that "dumb people" have been around way before the internet. They were just not as vocal as they are today, but if you actually talked to "the man on the street" about science in the 1970s for instance, you would have amazingly ridiculous "conversations". Plenty of people believed in things like satellites causing bad weather. I must have heard that at least half a dozen times in a few years back then. After that I mostly gave up on talking to people who didn't have higher education. It was completely pointless. The basics were just not there. One couldn't even get started with a rational explanation because the disconnect between the person's impression of reality and reality was in the way.

India has a GDP per capita of $2400 (below Bangladesh now) and is ranked around 130th in the world by GDP and PPP per capita. India's poor men are even worse off than Chinas and the Indian sexual slave trade with girls from poor provinces is bar none in the world. Where do you see winners there, exactly? These are highly unstable societies with enormous structural problems that are leading to endless misery. ;-)

  12586. That's the size of the gate. It's not the feature size of the total structure. If we translate the published transistor density into an effective "square" transistor pitch, then we get approx. 54nm between any two transistors. That agrees well with the published 42nm fin pitch, as far as I can tell. In any case, increasing the transistor count only buys so much these days because the actual integration limit is power dissipation.

  12604.  @LuaanTi  I invite you to read up on the legal requirements for stock offers and stock buybacks. I have been involved in one of these once because of a friend who worked for a publicly traded company at the time (which I had absolutely nothing to do with!). In the aftermath the SEC sent dozens of questions around to people who were associated with employees that were of the kind "Did you know and when did you know it that the company was going to offer/buy back securities in the time between...?". You can be sure that they were getting our banking information at the same time to look for suspicious account activity. At the end of the process two people were accused of insider trading and they went to jail for 18 months or so. If you think that this is a free for all game, then you are naive. Securities trading is highly regulated and you better abide by the rules or else there will be consequences.

  12614.  @jeffafa3096  It was to the folks with a physics education and especially to those of us who were in the field of high energy physics. The field had the very discussion she accused it of not having like 40 years ago. She consistently tried to make some of the most intelligent people in the world look like doofuses. That's the sign of a person with narcissistic personality disorder. Sabine's case belongs in the psychology and not in the physics department. Physicists can't help her. We are neither qualified nor certified to do that.
    1
  12615. @jeffafa3096 The problem with physics on the internet is not restricted to Sabine. Most YouTubers either oversimplify the actual facts to the point where they present a completely false mental model (this is especially the case for everything related to quantum mechanics) or they are completely uneducated about the subject matter to begin with and they basically just regurgitate hearsay in a game of telephone. Either way you are not getting useful information. This, by the way, is not even restricted to the internet. I would make the same statement about most layman books (Hawking in particular wrote some horrible mental models into his layman books that the physics world is still trying to exorcise from the public's memory... with little success.) I only know a few domains well enough to talk about them. Physics is one, electrical engineering (at the circuit board level) another. I do not talk about chemistry, biology and ice fishing in any level of detail. I simply don't know enough about them. What I can tell you is that Sabine often enough misrepresents physics badly enough to disqualify her from being a good source. Of course some of what she says is correct, but the context in which she puts those snippets is designed to garner attention and to increase her view count. So where do you find "the truth"? In the physics library and the laboratory... in form of a full time 24/7/365 physics career. I hate to break it to you, but physics is no different from playing the piano. Either you can play the piano or you can't. No pianist in the world can tell you how one plays a Chopin piano concerto in Royal Albert Hall. Either you do or you don't. There is no trying and there definitely is no "peeking in".

  12619.  @LennardA320  Yes, the cost+ scheme allows the contractor to charge a lot more than the actual project cost, but not because of the 10%, but because they can quote an almost arbitrary cost base. Now, a naive person may assume that the contractor pockets that money and all the government project managers are idiots. You can hold that religious belief until you actually meet a government program manager. I have. They are not idiots. They know exactly how much materials and services cost. Some of the people I worked with were among the sharpest minded people I have ever met. So why does the government "let" this happen? Because they have other projects with Bechtel that are not publicly disclosed and that they do not want to show up as a Congressional line item. Bechtel gets paid for those projects with excess money from the NASA contract. Did you never wonder why we are suddenly going back to the Moon? Because it's expensive and the US government needed an endless sink of money that they can hide secret programs behind. Unless, of course, you haven't noticed that there is a hot war going on in Europe and that the Chinese are also extremely active spying on us. Do you really think we are just standing by? Of course not. We simply aren't telegraphing either to the Russians or the Chinese what we are doing about it. What you should be really worried about, however, is the Saudi Arabian city called "Neom". The Saudis are pretending to dig sand for tens of billions of dollars, which looks even more crazy than the current moonshot programs of both the US and China. Of course they are not digging sand. They are hiding tens of billions of dollars of spending on their nuclear weapons program behind that project. I am sure you can find many similar, although smaller examples of "ridiculous" government spending around the world.

What you are really observing there are old professors retiring. That's all.

  12685.  @kristandevries4835 I agree. Respectful behavior goes a long way. Dialog is very helpful. Asking ones partner what they want in all situations, intimate and nonintimate, is a very good way to have a healthy relationship. That is what you need to focus on. With regards to "abused people" and the media... that's not exactly how this works. Nobody documents the actual abuse like human trafficking and domestic violence because the people who are doing that don't want to incriminate themselves. If you have a distorted thought process, then it's more likely about the dividing line between real and invented violence. The real violence happens behind closed doors and without cameras. If you want to do something about that... volunteer at a women's shelter. I know somebody who does and trust me... dirty images and videos are the least of their problems. They are dealing daily with actual men who are a danger to more than just their spouses.

  12686. Depends. If you are rewriting a search/sort etc. algorithm to make it O(nlogn) instead of O(n^2) for instance, then it's fine, especially if you leave the old code in place, just in case that it has fewer bugs than the new code. If you are simply doing it because you don't like somebody else's choice of method names, then it's completely wrong. What people call re-factoring is usually a thing between these two extremes, but a whole lot of it seems to be more about esthetics than actual functionality.
    1
  12687.  @MrDavibu  "Refactoring is more about data structures and how data is accessed and management of responsibility." That's my point. If refactoring moves the implementation or maintenance of a method from one team (member) to another, that's inefficient. People who were familiar with the code are now out of the loop and somebody has to learn it from scratch. Objects are, in many aspects, a false abstraction. In the real world "things" usually don't perform actions on themselves. A dog, for instance, doesn't walk itself. It is being walked. It may be walked by more than one person. It may be walked all by itself or together with multiple other dogs, which may not even belong to the same owner. So, where does walkingTheDog() belong? To personClass? To a dogOwnerClass that derives from personClass? But then we also need a dogWalkerClass that also derives from person but that does not have a fixed number of dogs as member variables, right? And no, one can not even exclude a more general walkingTheAnimal() method from catClass because there are plenty of people who are walking cats on a leash. :-) Linking actions to data is, in my opinion, a highly inflexible strategy that forces architects and teams to invent strange hierarchies that don't describe the real world well. Is it beneficial to press everything into such a narrow scheme? I doubt it. The only applications where I find classes and objects useful are GUIs. Everything else constantly tries to break out of this scheme in my experience. There is, of course, a need for libraries to isolate well defined groups of actions from each other. File IO is a different library than the low level SATA interface hardware library, is different from the file system library, which is different from a string library which is different from a word processor library. There is a natural hierarchy there. The word processor will never need to know about the block structure of a hard drive and the way the file system uses it. But then, again, these functions are so different that we would not be doing ourselves much of a favor by subclassing wordDocumentClass from stringClass from fileIOClass from blockDeviceClass from hardwareDriverClass.

  12688. That's not what the wave function does. The wave function describes the averages of an infinite ensemble of identical quantum systems. It says absolutely nothing about an individual system. There are only a few actual physical observables: energy, momentum, angular momentum and charges. What von Neumann calls "observables" or "measurements" in his book are histograms over these quantities. They have nothing to do with actual physics. Think of them as generalized Fourier transformations of the primary data.

  12733.  @knismo5842  I don't mind cosplay, either, I just don't mistake it for research into history. Recreation of history is not history, at least not on this level. As long as you are having a soy milk latte in the morning before you put on your gear, you are just kidding yourself. The best true anthropological research that was ever done, in my opinion, was Franklin's lost expedition. 129 men with the most modern gear of their time perished in a territory that was inhabited by primitive Inuit who could nourish themselves "of the land" just fine. Why? Because they did not inform themselves on how to actually survive in such an environment. A modern cosplayer would probably not last a week in the actual Roman Empire.

If you are the kind of "historian" who likes to shop bad data around, that's your problem, not mine, and it has nothing to do with the fact that DNA evidence is infinitely more reliable than any written record. Written records can be faked or they can be fiction to begin with (and most written records are, indeed, just that, you are welcome to visit an average modern library and compare the fiction with the non-fiction section). DNA can't be faked. If you have it, then you have it.

  12738.  @truckwarrior5944  But you are not entitled your own reality. Physical evidence is the best evidence and one day it will be the only evidence admissible even in the study of history. That's when history will turn into a scientific discipline instead of being among the arts.

  12753. OOP has nothing to do with languages. It's the strategy of coupling methods to data and of organizing both in class hierarchies. It can be done in any language. Whether you have to code OOP is decided by your boss, not the community.
    1
  12754.  @programmertheory  Syntactic sugar is just that. It doesn't help you to solve the problem, it just makes the solution look nicer. Your compiler strips it away anyway. In general I would suggest that the experienced programmer should focus on what matters, not on how it looks. Basically everything they tell you on the internet evolves around looks and/or point solutions to detail problems. Very little, almost nothing really, is about proper system design strategies. I don't know what Alan Kay thought, but OOP, at the core, seems about design reuse. It's not very good at that, but if you are on a machine that has 32kWords, like Kay may have been back then, then moving runtime stuff (like type checking) into compile time operations might be a reasonable idea. On a 32GByte, 4.5GHz machine it's a ridiculous micro-optimization. Runtime introspection is far more powerful and costs only a few nanoseconds. The easy with which dynamic languages solve problems is proof for that.
    1
  12755.  @programmertheory  There are no classes in machine code. There are no objects, either. There are only relative addresses, data segments (heap and stack), program segments and jumps/branches/subroutine calls. That's it. None of the beauty/documentation/structure shit that programmers spend 90% of their time on stays alive after the compiler is finished. Not even the execution order of the code. I used to teach computer science as a TA a long time ago. We didn't teach OOP. We taught machine design, algorithms and compiler code transformations. We wanted the student to understand the difference between code, compile time and runtime. Once you understand that, you will focus on what survives all the way to runtime and the problems that creep in between the two that have absolutely nothing to do with the source code. OOP is usually procedural. It simply documents data structures and method libraries differently than code that is not based on class hierarchies. Real FP doesn't exist anyway, at least not outside of the madhouse where they put copies of GByte size arrays on the stack to "prevent side effects". That's why our CS class taught pointers/references early on and independent of any language. They have nothing to do with code or even language design. They are a law of nature. It's much easier to point to the mountain than to move the mountain. The main problem of OOP is that it introduces strong couplings early, often and without any need. Who does it appeal to? The micromanager. It allows the architect to control the team and the business people to measure the performance of employees in meaningless classes/objects/methods per month metrics. I have mostly given up on OOP. I go with introspection most of the time. In your example there would be a field called whatAmI in my data structure and it would have integer constants for MAN, WOLF, WEREWOLF and NONE in it. Any method that needs to differentiate between these would use a trivial case statement to execute the relevant code. Does it cost one integer and a couple of nanoseconds to execute the comparisons against the constants? Yes. Do I care? No. This saves weeks of refactoring.

  12756.  @programmertheory  The students back then didn't. We had almost half the students fail the class the first time around. They were all complaining "But that question was not in last year's test!". You bet it wasn't. Neither were the same questions in it the next year. Those who repeated the course managed to pass the second time, though, so it wasn't unfair at all. The student who learned the most about CS that year was me, though. I really had to think through some of the basics and not just take the usual bullshit about coding and compilers for granted. That helped me out a lot during my PhD thesis when it came to analyzing other people's failed code.

It does not follow from de Broglie or even the full Copenhagen interpretation. Quanta having position has, indeed, never been observed.

Until not even that worked, of course, and the Romans went postal on Judea, anyway. If you look at history rationally, the Pharisees are the good guys and Jesus was a liability.

  12793.  @ub2bn  Of course the texts of the NT were written by somebody. They are certainly not homogeneous, though, and they don't agree with each other on crucial details (like when Jesus was supposed to return). If that corpus had been written by a unified body, it should look a lot more internally consistent. It isn't, which tells me that many hobby theologians of early Christianity threw their hats into the ring and some of the worst (like Revelations) struck enough of a note with the audience that they kept it. The resulting religious cacophony only sells well today is because nobody actually reads the bible. Most Christians do, at most, skim trough it without ever noticing the theological problems with basically every single part of the document.

  12794.  @ub2bn  Yes, the fish is always getting bigger. :-) Curiously, in the bible the water stories seem to be getting smaller. In the beginning god creates the oceans with everything in them. Then he drowns the entire planet. By the time of Moses he can only part a sea and then there is a man inside a whale. We come to Jesus and now a couple of pitchers of water turn into wine and a man walks on water... that's it. I have a feeling that we are talking about 19-20 orders of magnitude reduction in moved water volume over the course of roughly four millennia. Somehow the old man had really lost his water mojo.

  12807.  @AlexandruVoda  That sounds really cool, except that in reality there is no such debate in the physics community about interpretations. Working physicists either use Copenhagen or they are doing quantum field theory. I have never met a single physicist in my life who uses MWI since it's pointless. That includes the folks who preach it like gospel like Sean Carrol. We know how quantum mechanics works. Quanta are small amounts of energy. We teach that in high school. Where and when a quantum of energy will be detected can not be predicted. We can only predict the average behavior of ensembles of quantum systems. There are two cases: 1) that quantum of energy stays in ONE isolated system. For that we need a unitary equation like the Schroedinger equation. 2) The quantum of energy gets transferred to a SECOND system which we call the measurement system. The physics of the measurement system is being described by the Born rule. Copenhagen is not some kind of random magic. It actually describes the physical reality of the physical measurement process. None of the other interpretations do. They try to avoid it. Hidden variables are ruled out by special relativity. The only mystery there is why Einstein didn't understand that when he co-wrote the EPR paper. Bell certainly did understand it. He even invalidated his own paper in the end by pointing that out. Most people simply don't read the Bell paper to the end (well, most people don't read the Bell paper, period), so they don't notice that Bell himself already knew that he was talking total nonsense. :-)

  12818. Depends on how you are reading Planck and Einstein. Conservatively Planck says that thermal emitters can only emit light in quantized energy steps. This is not quite correct and it does not prove field quantization. Conservatively Einstein says that light transfers energy in discrete units to a metal plate in the photoelectric effect. This also does not prove field quantization and it still gets the property that is quantized wrong but it does thicken the plot.

  12820. There are no particles in nature. Something that doesn't exist can not have a state. What your detectors do is to absorb a small amounts of energy, momentum, angular momentum and charges from quantum fields. If you read a typical textbook on atomic physics carefully, however, then you will notice that the absorbed system properties ARE NOT linked directly to the quantum mechanical state (of an ensemble). They are linked to state transitions. If you want to see this in theory, then I would suggest that you read Heisenberg's matrix mechanics papers. It's clearly expressed in there. These details only got lost somewhere between Schroedinger and von Neumann and they are usually not explained properly in QM 101 classes. The disconnect between wave function based theory (which only talks about the measurement process in the abstract) and the actual measurement process (spectroscopy) is typically only bridged in experimental physics textbooks which the theorists never read.

EE is simply more mature than CS. The rate of change is slower and some things (like PCB design) haven't changed at all.

  12842. Probably not in a relevant way. We are artificially increasing absorption but are then removing more energy through the grid and through the radiation these panels give off during the night time. Overall it's probably mostly a wash unless we start to actively engineer the panels as efficient IR reflectors. The shade does seem to reduce evaporation, though, so plants will grow longer and better underneath panels. Eventually we will probably need this effect to offset the increasingly more arid conditions in the South of the US due to global warming. I have seen one science study that estimated the cooling in the Sahara due to increase in heating during the daytime, which I believe draws cold, moist air in from the ocean (we are creating an artificial circulation heat engine, I believe). The article was mostly negative about the impact, if I remember correctly. Even million square kilometer patches hardly seem to make enough of a climate impact to change rainfall substantially.

Yes, Paul was definitely a liar and so were the four Evangelists. You can find plenty of evidence in the text for that. The bible then ends on the ravings of a self-serving madman. There is nothing there that passes an intellectual smell-test and one can easily debunk that the text has any moral value. The leading social problem in the Roman Empire was slavery. The bible does not mention even once that slavery needs to be abolished. Quite the contrary. The NT tries very hard to appease the Romans on the matter.

  12849. So they are basically replacing the Born rule with a different but equivalent axiom. There is nothing to "recover" here. The Born rule describes physics that is different and not equivalent to the physics of the free (unmeasured) ensemble. Some theorists keep surprising me with their inability to see the obvious. At most one could prove that the Born rule (or any of its equivalents) is the only "additional" axiom that we need for the theory to be complete. In reality, of course, all of this has been made obsolete by quantum field theory.

His work is certainly an interesting literary experiment but that is all it is. I would agree that there are authors that are better in form of a book than as an actual play. Shaw is one and I think so is Jean Giraudoux, The characters of their plays are better left as abstract archetypical representations in the reader's mind than transformed into actual theatre or movie actors or worse... stars. But then... good luck getting a modern kid to read either Shaw or Giraudoux.

  12908. Time is that which the clocks show. Clocks are objects with rest mass that have an energy source and a mechanism that partitions this energy into equal portions that are being dissipated towards infinity by electromagnetic radiation. So, no, electromagnetic radiation "does not have time". It makes time. Photons also don't travel. What "travels" is the electromagnetic field. The only time an electromagnetic field has photons is at its sources and at systems where it gets irreversibly absorbed. The photon concept doesn't make much sense in the free field propagation case. Everything you are seeing was in the past. You can't change it anymore.

  12947. That must have sounded so cool in your head... and only there. In reality particles don't exist. There are only quanta of energy.
    1
  12948.  @tom47235  That's a common misconception. We are telling everybody in high school that "Photons are small amounts of energy.". This is, probably more by chance than by design, the correct way of looking at it. Both Planck and Einstein correctly interpreted macroscopic experiments (neither Planck spectra nor the original photoelectric effect measurements are resolving single photons) as signs of field quantization. Einstein did, however, add a completely superfluous and unfortunately misleading sentence in his photoelectric effect paper that won him the Nobel Prize. In this one sentence he claims that quanta of light have position properties. This doesn't follow from the experiment and it doesn't agree with anything 19th century physics knew about energy. It's just an ad-hoc fallback to Newton's corpuscular theory of light, which is 100% wrong. We can only speculate why Einstein did that. The sentence clearly passed the reviewers and to this day most people who read the paper probably read past it without ever thinking about its validity. The simple fact is that Einstein did not make this statement based on scientific observations. Quite to the contrary: it actually contradicts the experimental facts completely and is not compatible with our theoretical understanding of energy as a system property. More importantly, all quanta, including electrons, muons, neutrinos, quarks etc. are quanta of energy. They are the amounts of energy that is being exchanged between the free fields and the sources and absorbers in irreversible processes. Even the theory clearly says so if you care to look at it very carefully, i.e. beyond the "shut up and calculate" level, which is unfortunately the most common way that it is being taught. Curiously physicists have made this mistake twice before. Before heat was established as a form of internal energy, people talked about it as a "Stoff" called "the phlogiston". The phlogiston was supposed to be a material carrier of heat energy that was diffusing from one material into another whenever they made thermal contact. In very much the same way the "particle" nomenclature in quantum mechanics claims, for absolutely no rational reason, that particles are the carriers of the energy that gets exchanged in individual quantum processes. The second time we invoked a material carrier where there is none was when we claimed that electromagnetic waves were carried by the "aether". That, too, was just a materialist fallacy to explain energy flow as a mechanical phenomenon. Einstein overcame that fallacy in 1905 when he introduced special relativity. At the exact same time he invented a fallacy of his own that is based on the exact same misidentification of conservation laws with material carriers, by declaring quanta of energy to be material particles. Sometimes even physics is just a comedy of errors.

  12992. @ "The Copenhagen interpretations is 100% correct, most people simply don't understand it.". There are approx. 1 million physicists on the planet. Most of them don't understand Copenhagen, either, because of the horrendously poor way we teach quantum mechanics 101 in university. So that means at most one in ten thousand people understand Copenhagen. In my opinion it is closer to one in a hundred thousand. What's supposed to be wrong with that sentence?

That second sentence happens to be the rational starting point if you actually want to understand quantum mechanics for real. We don't start with that in QM 101 and THAT is the reason why virtually 100% of mankind is confused about it. In essence I only began treating you like a troll when you began posting troll stuff.

    1
  12999.  @Belti200  No offense to anybody, but this is trivial second year undergrad physics. We usually discuss this in thermodynamics and statistical mechanics classes (briefly). A measurement has to be an irreversible process because it has to leave a lasting record in a system that is different from the system we are performing the measurement on. Why do we have to transfer energy? Because everything has an effective temperature (third law of thermodynamics) and the amount of energy that gets transferred has to be >kT or else we can't distinguish the result of the measurement from a random thermal noise fluctuation. What is a measurement in quantum mechanics? It's the transfer of a quantum of energy from the quantum system to the measurement system. The measurement outcome is the amount of energy of that quantum. This is clearly expressed in Heisenberg's matrix mechanics papers, for instance. It's completely obvious in any textbook about atomic, molecular or nuclear physics. It's obvious in any experimental paper in high energy physics. If you ever meet a physicist who talks about measurement but can't tell you this stuff, it's time to stop listening to that person. They simply don't know what they are talking about. Peace!

  13043. @ Nobody of importance ever said that energy is quantized. Angular momentum and charges are. Energy and momentum are still subject to perfectly classical transformation laws that are a direct consequence of the Poincare group. Angular momentum is quantized because rotations are periodic. There is no such periodicity for translation symmetry and space-time is not even translation symmetric to begin with, so strictly speaking globally energy-momentum is not even conserved. Locally there is a near translation symmetry and energy-momentum is a useful locally conserved quantity.

  13053. That's very likely. If you estimate conservatively that only half of those who are infected get tested and\or test positive and those who have the disease remain infectious vectors for five days, then multiplying the number of positive cases with ten gives you a rough idea about how many infectious people you have out there. I find that during the omicron peak typically one half to several percent of the population might have been infectious, i.e. if you went to the grocery store, the likelihood of coming in contact with a vector was very high. We could have prevented the omicron peak only with nearly 100% vaccinated and boosted populations and effective social distancing, neither of which Western countries are willing to do.

  13062. Pretty much everything related to quantum physics can be calculated. That's an infinite number of possible questions, they are just not very interesting unless you are a physicist. The original suggestion of Feynman was exactly along those lines: to use quantum mechanics to answer hard questions about quantum mechanical systems. He wasn't suggesting that this was going to be useful for general computation. While one can prove that quantum computers can calculate every classical algorithm as well, it doesn't mean that they can do it efficiently (or at least substantially more efficiently than a classical computing device). What is going on here is simply that non-experts are (again) not listening to what the experts are telling them. ;-)

My comment is therefor in general for other products, including the industrial kinds that I used to design in the past. Having said that, it just occurred to me that the law may have run afoul of the interstate commerce clause because of that. But that's a different discussion.

  13108. One of the first things you will notice is that you are in a police state. Then you will notice that outside of these modern city centers in tier 1 cities there is a lot of old infrastructure. Public transportation during peak hours is a nightmare, so is traffic, if you happen to have a car. You will find that the majority of this glamour is built on top of poor people working really crappy jobs with next to no upward mobility. You will be bombarded with government propaganda everywhere, which is funny if you see it the first time but becomes very tiresome if you have to live with it. When you go on the internet the government listens in. You can't get to many Western websites (no chance to access anything from Google legally) and whenever you look for something rare, there is a 30 seconds delay before the web page builds up... that's the time a government watcher (or an AI) needs to look at your request and to approve it.

  13111. There is nothing to learn here. We are teaching in second year physics that observations are irreversible energy transfers. We gave you an example of those relating to quantum mechanics in high school when we explained the photoelectric effect. All of this is trivial, people are just not paying enough attention in school. :-)
    1
  13112. Most of the "information" you are hearing is either open source or misinformation. If you were paying attention to US strategy in particular, its a carefully crafted crescendo. First there were not going to be heavy weapons. Then there were heavy weapons. Then no tanks... until there were tanks. Then there were no planes, until there were planes. Now there are no long range missiles... until next Tuesday, when there will be long range missiles. If I were Putin I would not put this to the ultimate test... whether the US is willing to lend Ukraine a few nukes. ;-)

  13113. They have been talking it up for forty years, but they simply didn't have the political crowbar to move anything. Now a few crazies figure they can use Ukraine for that purposed.

  13115. SpaceX is controlled by a very stringent set of national security laws and it is strongly tied into federal funding. There is only so much Elon Musk can do without running up against the powers of the federal government. I wouldn't worry too much about that. As others have remarked... what is happening here is more a matter of psychology. Musk seems to be have become addicted to positive feedback from his followers. I am not completely certain but he may also be on (legally prescribed) drugs. A psychologist would probably not call his personality disorders "well controlled", though. He is becoming more eccentric as he ages, which is not unheard of for billionaires in his field. He actually seems to parallel the life of Howard Hughes on some level. Let's hope for him that the ending will be better.

  13117. You don't have to get vaccinated. My antivaxxer relatives had natural immunity for approx. 18 months before they got infected, again. You should be good for a year, maybe two if you are lucky. That's sort of what they are saying about the vaccines... it will take a booster at least once a year. So, yes, a good covid booster infection will soon be in order.

  13129. There is no "smooth transition". Why? Because there is no smooth transition between closed, reversible and open, irreversible. These are hard binary choices that we have to make. Either a physical system is completely closed and isolated and then it has fully reversible dynamics or its open and then it has irreversible dynamics. It's already like that in classical physics, we just don't teach this fact very well, so people get confused when it comes to quantum mechanics.

I will give you some more attention, though, until your Mom comes home to fix your dinner, if you insist. ;-)

  13145.  @UKCheeseFarmer  Child, I didn't give a rat's tail about Putin before this war of choice, nor do I give a rat's tail about him right now. The simple fact is that the three day special military operation has now been going on for over 500 days and NATO will make sure that it will last 3000 days or 6000 days if necessary. If Russians want to put up with an old man who has lost his mind that long, that's just fine with me. I am not going to be the one who will starve, grieve or die because of him. ;-)

  13148. You have a point. But let's say we would make an actual online science course for you. Would you really watch fifteen 90 minute episodes to learn the basics of e.g. electromagnetism or quantum mechanics? These kinds of lecture series are online. You can see how many people are watching them. Now imagine taking five years worth of these classes (six to eight a year!). That is what it takes to learn a hard scientific discipline these days. Plus all the homework, exams and three to five years for a PhD thesis. Very few people have the stamina for that much suffering. ;-)
    1

  13175. Why should the US president declare war against a Russia that is already bleeding out? That makes no sense whatsoever. If your opponent is on the floor and blood is gushing out of his wounds you simply step back twenty feet and wait until he is done. There is no need to endanger yourself trying to hasten the process. It's actually far more fun to watch the suffering before the inevitable happens. In any case, we could give our entire NATO stash of artillery and shells to Ukraine (which at that point will mobilize one million men and possibly another million women) and we would still not have expended even a single piece of precision rocket ammunition, not one cruise missile of thousands, not a single laser guided bomb out of tens of thousands, not a single jet fighter and not even one bomber. We would have an intact air defense system and all our spy satellites and electronic countermeasures. We would be strategically just as strong as before, but Russia would have basically no mechanized ground forces left, it would already have lost most of its air power. Its military demoralized and many of its best officers dead. Dude, Putin didn't think this through. He is simply an insane 70 year old man who is sitting in his Berlin style command bunker and is mostly afraid of his own people. :-)

  13176. You keep hearing that because most people who are talking about quantum mechanics on the internet don't understand quantum mechanics.

Economic development behind the iron curtain was far slower. In West Germany you could easily buy a dozen cars a day if you had the money, in the German Democratic Republic you could buy one model... if you were willing to wait for 20 years. ;-)

  13193. Ah, so you are from the "Can't chew gum and walk at the same time" congregation.

  13194. It would also be technically wrong. Social democracy is regulated capitalism. None of the Scandinavian countries is even borderline socialist. The clearly socialist military-industrial complex in the US is economically larger than the entire GDP of either of the Scandinavian countries.

  13195.  @rv706  The US. An arms producer can not sell products without government permit. That is socialism.

  13196. And by "heavy infection" you mean two weeks of vacation on the ventilator? :-)

  13197.  @Marshall-lb1ei  California is currently generating 60% of its electricity from renewables and 0% from coal. All you are telling me here is that you can't do as well as the people in California. Why do you like to look like a loser on the internet? What's the upside of that? ;-)

  13199.  @ДенисШевченко-р6й  OK, kid. Let me give you some more attention. You are clearly very needy. ;-)

  13202. While the sarcasm is appreciated, there are signals that political opinions are dependent on left/right brain dominance, which most likely does have a genetic component. The relatively close divide between left and right leaning voters in many countries indicates that the appeal of emotional policies on the political right and factual policies on the political left is, indeed, somewhat coupled to our biology. If that is the case, then we need to seriously rethink the way we do politics without disenfranchising entire voting groups.

  13203. You can't run anything backwards from a detector. The definition of detector is that of an irreversible process.

  13204. Criticism has to be well founded in facts. Patriotism is just a word that is being used to make cannon fodder out of idiots. ;-)

  13206. It could have been... but it wasn't. There are, of course, images of the Russian flag being hoisted on the government building in Kiev... oh, wait... there aren't. ;-)

  13207. Structures in C can have function pointers and one can do OOP in assembler if needed. It's really not a big deal... and totally not worth it, either.

  13208. Nowhere. Your consciousness didn't exist until you were born and it won't exist after you are dead, either. I admit that's not a particularly nice thought, but nothing stops you from believing in something like reincarnation. Since the sequence of you went like Nothing-You-Nothing, there is really no logical reason no to extend this to ...-Nothing-You-Nothing-You 2.0-Nothing-You 3.0-Nothing-... and so on. Your memory gets erased every time, of course, so you can't remember your previous versions, but then... do you really want to remember a crappy life forever? Isn't a fresh start a million times better? That's all there is to it. Enjoy your endless reincarnations.

  13209.  @TimecastGaming  Except that my consciousness understands quantum mechanics and yours doesn't. Mine wins. ;-)

  13212. Except that fusion can easily produce energy gains of hundreds of millions, if not billions. It's called a "thermonuclear warhead". They are absolutely marvelous energy production devices. :-)

  13214. In free societies laws are not retroactive, so even if pornography became illegal you could not be punished for your past activity. In non-free societies they can do with you whatever they like anyway.

  13215. Why would it matter? Most bitcoin has already been mined. From here on it's more or less just eternal losses until there will be no bitcoin left.

  13217. It won't work out too well for Africa, but then... absolutely nobody cares about Africa at the moment.

  13218. Is something that doesn't exist orthogonal? No, not really. :-)

  13219. Supporting young families doesn't help. Plenty of countries are trying that and they are all failing. Single kids don't have a strong psychological desire to have children and certainly not to have multiple children. Quantity also doesn't help. China needs a smaller population but much higher GDP per person. Achieving the latter is the hard part.

  13220.  @andersemanuel  The facts in industrial nations contradict you. The birth rate is usually significantly below 2. Rearing children is a pain and expensive. It's not fun and it's not necessary. Rich people don't give a rat's tail about what poor people do. You are clearly not a rich person. You do have your brain stuck in the past, though. :-)

  13221.  @andersemanuel  I am sure they will all make lots and lots of grandchildren for you. And this is where I turn around and walk away slowly... ;-)

  13222. See, you and Sean Carroll are great examples for how belief totally messes up the human mind.

  13223. How do we know what? How quantum mechanics works? It took about 100 years of experiments and 20 years of very hard guessing. In hindsight it's trivial and one can derive it in about half a dozen pages of slightly above high school algebra from a set of mathematical axioms that are named after Kolmogorov. Hindsight is always 20/20. ;-)

  13224. Where did you get that bullshit from? Your own rear or somebody else's? :-)
