  518. Who on Earth said that they were white European? Nobody did :) Hindi, Gujarati, and the other modern Northern Indian languages are derived from Sanskrit -- or rather, the kind of Sanskrit that common people spoke and not so much the highly standardized formal form of Sanskrit that Pāṇini described/invented. This is no different than how French/Spanish/Italian/Romanian are derived more from the common man's vulgar Latin than from the highly standardized prestige form of Latin that Cicero and Caesar wrote in. So where did Sanskrit come from? Was it invented one afternoon around teatime? Was it a purely Indian invention that took place in India? No. The predecessor to Sanskrit was brought into India from the North West -- and it was very similar to the language that evolved to become Persian. The common ancestor to that -- and to languages like Latin, Greek, Albanian (all very different and separated for thousands of years) and the Germanic and Slavic languages came (roughly) from an area in South-East Ukraine and a bit further East from that (the Pontic steppes). Nobody is saying that Europeans invaded India. Nobody -- except bonkers Indian nationalists -- is saying that Indians invaded Europe. What they are saying is that lots places were invaded by a people that originally (as far back as we know) came from the Pontic steppes. This was pretty obvious a long time ago just from archeology and linguistics -- and the way people looked. Shared elements in mythologies and religions also strengthened the hypothesis. We didn't know exactly where the original home of the protoindoeuropeans was but the Pontic steppes were always one of the leading candidates. Now we have even more confirmation of all this through the use of ancient DNA -- they literally look at tiny pieces of DNA in tiny bits of old skeletons and compare them! How cool is that? These (rather brutal and nasty) guys were our common ancestors, unless you are entirely Dravidian, in which case it is only large parts of your culture that came from them: https://en.wikipedia.org/wiki/Yamna_culture Btw, we have lots of really, really, really old Indo-European writing -- not just in (old!) Latin or (even older) Greek. We also have some so old that it predates not only the Latin, Greek, and the Brahmic script. It is so old that it even predates Linear B! It is written in cuneiform on clay tablets + we have toponyms, personal names, and loanwords in writing in non-Indo-European languages that are even older. We really have a lot of material to base the Indo-European hypothesis on. We don't know whether the Indus valley civilization crashed because of the, let's face it, barbarian Aryan invasion(s) or whether the Aryan invasion(s) were made possible because of the crash of Indus valley civilization. All we really know for sure is that there is a curious coincidence in the timelines. Northern Europe was not well developed during the time of the Indus valley civilization. The Hittites and Luwians seem to have been quite advanced, though.

  628. They have a good excuse for the yellow river. It is yellow because of very, very fine grains of stone suspended in the water (called “loess”). They get blown into the river by the wind while the river is flowing on a high plain at the beginning of its course. Then it flows fast downhill for quite a while. The speed and the turbulence whisks the water so the loess stays suspended in the water. Then the river comes to a long stretch that is almost flat. The river flows slowly, it becomes wide, and the loess slowly falls out of suspension and gets deposited at the bottom. And that means there are many places along the river where the riverbed becomes lower and lower (and wider and wider) until suddenly the river decides to change course. There is not a lot that can be done about it. The rest of the floods are due to human folly, just like everywhere else, plus a few places where the river is bordered by steep mountain sides (also typical for flood-prone rivers elsewhere). Rainwater flows down the mountain sides, there is nowhere for the river to go except “up” and “fast”, ... By human folly, I mean: building villages and cities right next to the river, often with a mountain side behind the city... or hemming the river in with walls along its course so it can’t overflow to meadows/fields... or straightening the river out so it flows quicker.... or building dams to take up the rainwater but then not emptying them before the rain comes... Rivers need flood plains to overflow to so they don’t overflow cities/villages!

  802. ​ @kngharv  Yes. But when you zoom in, some of those incremental improvement are not that simple. There are lots of total shifts of technology in delimited areas. The improved power electronics did not come about because power MOSFETs became better (which they did) but because of a different type of "transistor", the IGBT. And that's just one example. If you zoom out, it looks like incremental improvement but if you zoom in, you can see it is a new technology which happens to share most of its "ecosystem" with preexisting semiconductors and which is compatible with preexisting electronics. Here's some background reading... https://en.wikipedia.org/wiki/Insulated-gate_bipolar_transistor (just look at the table if you are in a hurry) Our grids are AC for one reason only: it makes it a lot easier and cheaper to transform the electricity down from high voltages (and low currents) to lowish voltages and high currents close to the consumers. The power lines are really just very, very long resistors and the loss in a resistor is proportional to the current. The power (energy per unit of time) equals the voltage times the current, so if we can step the voltage up and the current down, we get lower losses. Transformers are good at this job but they require alternating current. Other methods have been used, for example electric motors that drive dynamos, but they are not as efficient. With modern power electronics, we finally have something that can do it better than transformers and without the alternating current. HVDC is useful for transmitting electricity with smaller losses = it's practical go much longer distances + underwater in more cases than before. The DC part also means that the connected subgrids don't have to be synchronized, which they do for AC. That's a huge deal. It makes it much less risky to connect up gigantic powernets because the risk of cascade failures is much lower. And we want our nets to become bigger because wind and sun are intermittent power sources but hopefully the wind will be blowing somewhere and the sky will be clear *somewhere*. It also makes it easier to use pumped storage for "peak shaving" -- pumped storage usually requires mountains and low population densities but the usefulness requires industry/cities. Better electronics (computers) and communication (internet) also makes it easier to keep synchronized grids running. https://en.wikipedia.org/wiki/High-voltage_direct_current We have a big connected grid in Europe and we are trying to make it bigger (but less synchronized): https://en.wikipedia.org/wiki/Synchronous_grid_of_Continental_Europe https://en.wikipedia.org/wiki/European_super_grid https://en.wikipedia.org/wiki/List_of_HVDC_projects#Europe Pumped storage: big lakes (possibly artificial) at high elevations + a big height drop + turbines that can turn into pumps. https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity It's currently the best/cheapest energy storage method but it is not feasible everywhere + we have more or less built what we can in the West and some of them do have a local environmental impact. Other options for energy storage is batteries, of which lithium-ion is clearly the technology to bet on. Lead iron used to be cheaper (and might still be cheaper for a couple of years more) but lead is really unpleasant whereas lithium-ion batteries are safe enough to put in landfills (but can also be recycled). Lithium-ion have had a superior energy density for a long time but the prices have been too high, particularly when taking the low cycle count into account. Every single charge-discharge cycle wears a little on the battery and lithium-ion used to have a limit of a few hundred cycles. This has been improved immensely in recent years, mainly through the use of better additives. The technological enabler for this was a better measurement device that could measure microscopic wear on a battery over a single cycle. It's basically a really, really, really good amp meter. Prior to that, researchers had to perform many(!) cycles in order to compare their additives. This device was developed in Jeff Dahn's lab at Dalhousie University: https://www.dal.ca/diff/dahn/about.html There's a reason why Tesla has been working closely with him for about a decade... Tesla sells huge batteries commercially and expect that part of its business to grow a lot: https://en.wikipedia.org/wiki/Tesla_Megapack Tesla had a "Battery Day" event last year to tell investors about their battery technology, both current and upcoming. The press mostly ignored it but they showed several things that will change the world because they promise to make lithium-ion batteries much cheaper to produce (and also better than they are now). The official stream (140 minutes): https://www.youtube.com/watch?v=l6T9xIeZTds Much shorter version (16 minutes): https://www.youtube.com/watch?v=HK79ioBW8Mg The main competition for lithium-ion batteries for the grid is flow batteries. Unfortunately, they tend to use big tanks of really nasty chemicals (which may have to be heated to work properly). They are also unlikely to be able to compete with future lithium-ion batteries. https://en.wikipedia.org/wiki/Flow_battery

  996. Lance Armstrong -- star is also an old word, that doesn't mean that the Romans did all the important astronomy and that the contribution from the rest of Europe (or the contributions after the Romans) were small. No, by modern mathematics I mean modern mathematics and not just the binary numbers (Leibniz and many others). Things like proper linear algebra, including understanding how polynomials are vectors and how to make sense of what it means for two polynomials to be orthogonal. Understanding how Fourier series and the Laplace transform both turn out to be linear algebra as well. Or graphs -- and how they are also (sort of) linear algebra. Or things like modern number theory (which is about patterns in positive integers) uses calculus and complex numbers to say useful things about positive integers. Or topology, how to talk about shapes in an abstract manner without ever talking about actual positions. Some formulations of topology don't even need to talk about points! It is no longer solely a European endeavour anymore -- Ramanujan made huge contributions to number theory, for example -- but it pretty much was for a long time. And Arabs contributed very little back in the day -- and still don't. And a lot of what has been attributed to the Arabs was really developed by others. The decimal positional number system is a great example of that. Furthermore, just because someone wrote in Arab under an Arab name you shouldn't jump to conclusions. Many of them were from other peoples who just happened to live under Arab occupation. Many of them were also persecuted by their Muslim rulers and were executed, lived for years in house arrest or had to flee and live in exile. The European civilization does look it is in a decline at the moment. I hope we kick out the Muslims and lock up the Communists, otherwise we ARE well and truly fucked.

  1716. It has definitely evolved! SpaceX' Starship does things a lot differently (and better). There is no need to drive uphill to the launch pad and downhill afterwards, for example. The reason why they do that at LC-39A is that rockets need flame trenches and big rockets need big flame trenches. You can't really dig down into the mud/water there and build yourself a viable flame trench, but you can build on top of it and keep the bottom of your flame trench at about normal ground level. SpaceX just has a big round thing on (thick!) stilts that they put the rocket on top of. That means they can drive up close to it with a standard oversize load vehicle... and then they lift the empty rocket op with a crane. They also don't need to stack the rocket in an extremely tall building -- they can do the stacking out on the launch site. They don't need a special mobile launch tower and launch pad -- because the rocket isn't transported in its stacked form and because they designed the rocket better so it is easier to hook it up to pumps for fuel, purging gas, helium (if necessary), and electricity. They can test the whole thing with nothing but a Liebherr mobile crane (which weren't nearly as big or as good back in the 60's!) and an oversize load truck. They have a fixed tower that they use for carrying the "Quick Connect"-arm (which supplies liquids and electricity right up to the launch). They also put a combined crane and "catcher" on it. The crane can lift the rocket stages for stacking and unstacking... and it can catch them when they return to the launch site from space. The tower itself is built from 1) mostly identical elements that can be stacked and 2) each element is built from a number of large tubes. That means the tower itself is quick and (relatively) cheap to build, compared to the NASA launch towers. The crawlers are beautiful brute-force solutions to a problem that no longer exists...

  2025. The whole world did -- and then forgot it again because it happened so long ago and it really isn't anything special anymore. The US has had massive radio antennas like this for 50+ years. The same with the Soviet Union (then)/Russia (now). The same with ESA. There are even commercial networks like this you can buy time on. Which brings me to the next point: China needs more than just a bunch of these antennas in Northern China. The problem is that the Earth rotates... So they really need at least three groups of big antennas spread around the globe. The US has that. Russia has that. ESA has that. Several commercial companies have that. They were used for the Apollo missions, for the Soviet robotic missions to the moon, for the missions to Mars and Venus, for the Voyager probes, for New Horizons (the probe that flew by Pluto in 2015), for the many asteroid and comet missions from the US, Europe, and Japan, etc, etc... NASA/ESA/ROSCOSMOS (Russia/ISRO (India) currently have active observation satellites in orbit around Mars -- how do you think they communicate with them? So: they aren't really anything special. Everybody else already have them. China doesn't have enough to be self-reliant. China could just have bought antenna time commercially or they could ask NASA/ESA/Russia nicely about borrowing their antennas -- which they will have to do anyway.

  2273. If the Republic of India is a country, then so is the European Union. It looks a lot like a country with laws ("directives"), a parliament, a court, a government ("commission"), a president, ministries ("directorates-general"): https://en.wikipedia.org/wiki/Institutions_of_the_European_Union https://en.wikipedia.org/wiki/Agencies_of_the_European_Union https://en.wikipedia.org/wiki/European_Civil_Service#Directorates-General It sort of has a foreign policy, including embassies (that are called "representations" because the EU is totally not a country): https://en.wikipedia.org/wiki/Common_Foreign_and_Security_Policy https://en.wikipedia.org/wiki/Foreign_relations_of_the_European_Union https://en.wikipedia.org/wiki/European_External_Action_Service Note how the US, Russia, India and China all have a super important embassy in Brussels that just happens to be really, really big? And that there is a big and important "representation" in Washington, Moscow, New Delhi, and Beijing as well? The EU military is not entirely coordinated yet. Almost all of it is under national control -- but that was also the case in Germany when WWI started (Germany then consisted of 25+ states/territories/cities) and we would definitely call Imperial Germany a country. https://en.wikipedia.org/wiki/European_Union_Military_Staff https://en.wikipedia.org/wiki/EU_Battlegroup https://en.wikipedia.org/wiki/Military_of_the_European_Union Satellite support is really important these days: https://en.wikipedia.org/wiki/European_Union_Satellite_Centre https://en.wikipedia.org/wiki/European_Space_Agency#EU_and_the_European_Space_Agency https://en.wikipedia.org/wiki/ESTRACK https://en.wikipedia.org/wiki/Copernicus_Programme https://en.wikipedia.org/wiki/Galileo_(satellite_navigation) Practically all the satellite/space stuff is dual-use: https://en.wikipedia.org/wiki/Dual-use_technology France et al are still keeping some of the spy sat technology to themselves (but will undoubtedly share info with the rest of EU if need be): https://en.wikipedia.org/wiki/Pleiades_(satellite) Pleiades is just one example. And there is the money: https://en.wikipedia.org/wiki/Euro#Direct_and_indirect_usage https://en.wikipedia.org/wiki/Eurozone https://en.wikipedia.org/wiki/European_Central_Bank https://en.wikipedia.org/wiki/European_System_of_Central_Banks We even have vassals/protectorates: https://en.wikipedia.org/wiki/High_Representative_for_Bosnia_and_Herzegovina https://en.wikipedia.org/wiki/European_Union_Police_Mission_in_Bosnia_and_Herzegovina https://en.wikipedia.org/wiki/EUFOR_Althea https://en.wikipedia.org/wiki/European_Union_Special_Representative https://en.wikipedia.org/wiki/European_Union_Rule_of_Law_Mission_in_Kosovo https://en.wikipedia.org/wiki/United_Nations_Interim_Administration_Mission_in_Kosovo https://en.wikipedia.org/wiki/Military_operations_of_the_European_Union Actually, I think the EU is probably more of a country these days than India is.

  2277. Nathanael Sallhag Eriksson -- not every country looks like Sweden. Berlin has its own government, Bruxelles has its own government. Åland has home rule. Scotland, Northern Ireland, and Wales have their own parliaments but they are still part of the United Kingdom of Great Britain and Northern Ireland. https://en.wikipedia.org/wiki/Federation https://en.wikipedia.org/wiki/Confederation https://en.wikipedia.org/wiki/Confederation#European_Union https://en.wikipedia.org/wiki/Federated_state The European Union didn't start out as a country and it may not yet quite be one but it has been moving in that direction since its founding. Everybody knows that many of its citizens (maybe even the majority) don't like that so they stick to a polite fiction that the EU is totally not a country. Real countries have flags (oops), laws (oops), courts (oops), military (oops), foreign policies (oops), environmental protection agencies (oops), central banks (oops), passports (oops), ... But we don't have stamps! ;) You rightly say that we don't have an official language/a common language (two different things). But a) countries do not need to have official languages. The USA doesn't have one. And they can have more than one (Switzerland, Belgium, South Africa, India, etc.). It is also quite normal for federated states to have decentralized education -- the US Department of Education wasn't founded until 1979, for example. It is also quite normal for countries to have areas/territories in which not all laws apply -- Svalbard is an obvious example for Norway. That all EU member states have various opt outs and special cases doesn't mean that EU law isn't a thing. It is also quite normal to have separatist movements in countries. Think of the Scottish National Party and the referendum they had in 2014. Northern Ireland had a long low intensity civil war about independence. Corsica, the Basque country, https://en.wikipedia.org/wiki/Scottish_independence_referendum,_2014 https://en.wikipedia.org/wiki/The_Troubles This list is not entirely serious -- Bornholm does not have a serious independence movement -- but it is a good place to start: https://en.wikipedia.org/wiki/List_of_active_separatist_movements_in_Europe Finally, there is no hard and fast rule about one to one correspondence between countries and currencies. The real world is far more complicated than that. China consists of mainland China (using the yuan/renminbi), Macau (Macanese pataca), and Hong Kong (Hong Kong dollar). There are countries with an official currency but with widespread use of US dollars and/or Euros (Zimbabwe!). There are also countries in which different territories nominally use different currencies which Just Happen to have a 1:1 exchange rate (kroner in Denmark/Greenland/Faroe Islands, 117 different kinds of pounds for the UK and dependencies).

  2291. Yes, there is such an app! Actually, there are several but the best one is probably Skritter (which comes in two versions: one for Chinese and one for Japanese). You are continuously tested on tones, meanings/translations, and on how to write characters (stroke order and direction is fixed and important). The fixed stroke order makes it easier to learn the characters because you combine two systems: visual memory and motor memory. There is a system to the madness but it is not as much of a shortcut as one would think. Many characters have one or more semantic components (simpler characters that each mean something) and one or more phonetic components (simpler characters that once sounded somewhat like the composite character). That helps a lot once you have learned the first few hundred characters. The first hundred or so characters are probably the hardest to learn because you don't know anything about what you should pay attention to and what you can ignore + you don't know which characters are similar or how they combine into more complicated characters. It's just like how it took time to learn the difference between 'd' and 'b' and 'p' and 'q' (and 'O' and 'Q') when you were 6 years old. Pleco is a really good dictionary app that lets you look up multi-character words, individual characters, the constituent parts of each character, etc. If you are an absolute beginner, you shouldn't start out by learning lots of characters. HelloChinese is a very good app for beginners -- apart from all the standard language learning stuff you expect in an app, it also has speech recognition so you can get the tones and all the difficult new consonants right. Lingodeer is a new app for Chinese, Japanese, and Korean which also has speech recognition (but not as good as what HelloChinese has). It is so new that the iPhone version isn't out yet but the Android version is very nice (and it works well on the quite under powered Samsung Galaxy J1 -- I have the old version with 512MB RAM and a dual-core 1.2GHz Cortex-A7 running Android 4.4.4).

  2626. It's actually even worse than that. Every step of the way, Greece was forced to promise to do something eminently sensible in return for the next bailout, and every step of the way, Greece dragged its feet, refused to implement part of the deal or even tore down something that had already been implemented. An example is the way unemployment benefits works (or worked -- I'm not up to date with the situation). The old system required people to show receipts for their expenditures which they would then get reimbursed for. This is an extremely slow and inefficient process (but it requires lots of public sector workers!) and it doesn't let poor people manage their money wisely, for example by saving up for bigger expenses (that could even be investments in a better future) and it gives no incentive to poor people to find cheaper alternatives. So it is not a good option for the people on unemployment benefits and it is expensive. But on the other hand, it means the ruling party can find lots of jobs for people who are friendly to the party. And those people also have a chance to be nice to people they know (or somebody else with the right guanxi knows) and less nice to people they don't like. Early on, Greece was forced by the EU to implement a small scale experiment where people just got a lump sum every month, just like they do in Northern Europe. It's cheap, fast, efficient, provides better incentives for the recipients, and makes it harder to cheat the tax payers. One of the first things Syriza did was to scrap the experiment. There are many, many more examples like that.

  2673. The Lothian birth cohort study is still ongoing. They have several “generations” of old 11+ scores available — those were the “intelligence tests” that Haier mentioned early in the interview. The oldest test takers are pretty much dead now but they are studying the next cohorts now. It is still the case that the lowest scorers die first and that the highest scorers are healthier and have better lives. Haier misrepresented the origin of the tests, though. The kids were not tested to satisfy intelligence researchers but to sort them into 2 or 3 types of schools, according to their talents. The Flynn effect is known to have been stronger for people at the low end of the scale and practically non-existent at the high end — so a likely cause is better health for the poor. It is also known to be (much) stronger for some IQ tests than for others — with the obvious possibility being that they are more trainable and that school trains better them now than it used to. Raven’s progressive matrices shows a particularly large Flynn Effect. A recent study of about 4000 random people in England, who were given IQ tests and whose DNA was scanned on DNA chips (which checks for common single-nucleotide polymorphisms, that is, differences), showed that the correlation between people’s DNA similarity and their IQ similarity also exists for really small DNA similarities and for which “the environment” cannot be used as an excuse. In other words: we know intelligence is real, we know it can be measured, and we know that it has a large genetic component. I think it was published by Robert Plomin.

  2779. Robert Thomas, no it has not peaked yet. There's still a lot that can be done with additives -- and since it was only about two years ago that good measurement equipment for test cells was developed, we should expect development of those additives (and other parts of lithium ion cells) to progress much faster now. Additives help with temperature sensitivity, charging speed, heat losses during charging, and the number of cycles the cell can handle. The density can be improved not only by using thinner layers in the cell (it's basically a rolled up very long and thin flat battery) but also by using finer carbon grains for one of the electrodes and by the use of additives again. It can also be improved by adding small amounts of silicon -- this is something Tesla and Panasonic have already started to do but there are good reasons to expect them to gradually raise it from a few percent to 20-30% of the carbon. There are problems with silicon but additives can probably solve some of them. Jeff Dahn, Dalhouisie University, and his group have really pushed the limits of how well charging and discharging can be measured. It turns out that they can get information from a few charge/discharge cycles (or even just a single cycle) that previously took hundreds of cycles to get. That makes it much faster and cheaper to develop battery improvements. The point of improving the energy density is not so much to make the batteries smaller as to make them cheaper: if you can get more bang out of the same materials you don't need as much of them, which makes same-size batteries cheaper. Current lithium-ion batteries take a long time to produce (weeks or at the very least days), mostly due to a "maturation" period after the production proper where they are put through a special charge cycle (or several charge/discharge cycles) while their temperatures are raised in a specific way. If they can make that faster, they can make cheaper cells. Again, this seems to be something that can be handled with additives -- and it looks like something Dahn's group has looked into. They have published papers that almost say something about this but I expect the actual information to be proprietary to Tesla. Other groups have their own ultra-precise charging monitors (commercialized by people who used to be in Dahn's group) so they are very likely doing their own research into this as we speak. So, to sum up: - they are likely to become more energy dense, which is not particularly important by itself - they are likely to become faster to charge - they are likely to become both more cold tolerant and more heat tolerant - they are likely to waste less energy in the form of heat while charging - they are likely to be able to handle a higher number of cycles - they are likely to become faster to produce - they are likely to become cheaper. Much cheaper. Your Jetta is going to remain cheaper for some time -- perhaps more than a decade -- but EV cars are going to become cheap enough that their other upsides outweigh the price in perhaps a decade for many people. Probably for almost everybody in two decades. And to get back to the original subject: this limits how much effort it is worth putting into improving small combustion engines.

  2895. Jack, they had really damn good engineering and science. They also had a damn good production apparatus and they had lots of natural resources within their own borders. They had a fantastic General Staff and they had a much better officer corps, everybody could read and write the same language (even including all the minorities in the fringes of Germany), and soldiers were allowed and expected to do much more thinking of their own in the field. It was much less top down than in the other countries involved in those wars. They were also smart enough to use lots and lots of subs. (Well, that arguably cost them dearly in the first war, where they sank a British ship carrying munitions and some American civillians -- despite an organized campaign in US papers to warn people off -- which was used as a pretext for the US to join the war openly. The ship was a legitimate target according to international law at the time, but the law also said that the Germans were supposed to try and save the people on board, which was completely unrealistically to do with a sub.) On the other hand, they were dumb enough to waste an enormous amount of money, manpower, and precious materials on the V-2 project which had very little military value as long as one couldn't pack a decent bomb into it -- and one couldn't, until the nuclear bomb had been not only invented but miniaturized a bit. The V-2 project was bigger and more expensive than the Manhattan Project, so if the Germans had gone for that instead...

  3425. "Renewables" are precisely the problem. Wind/solar sources vary widely in how much electricity they produce and that can only partially be predicted. Something else needs to produce electricity when they don't -- and that something else has to be cheap and ready to turn on/off at a moment's notice. That something else is gas -- via pipelines, not LNG. Gas in pipelines is cheap, LNG is not. If we had relied on nuclear instead, we wouldn't be having this problem. Or if we had allowed fracking in Europe, we wouldn't be having this problem. And if we had relied more on electricity for heating and less on gas, we would be having a much smaller problem (in the near future when winter comes). It is more energy efficient to burn gas at a power plant and drive a heat pump with it than it is to burn gas at the consumer's house to generate heat. If we had great energy storage (in terms of humongous amounts of cheap, long-lasting batteries), we wouldn't be in this mess and renewables would work really well without pipelined gas. It will unfortunately take a couple of decades before we can manufacture that many (let alone do it cheap enough). Some European countries, due to accidents of geography, have mountains and valleys of a form that don't lend themselves well to agricultural purposes (=> low population density) while lending themselves excellently to hydropower (with pumps to move water up into the reservoirs). Those countries can use their reservoirs as de facto batteries (this is called "pumped storage"). Which are those countries? Basically only really Norway, Wales, and Scotland. Small parts of other countries can do it as well -- and they often already do. Unfortunately, hydropower is pretty harsh on the local environment + cause a bigger danger to the downstream population than a nuclear power plant does.

  3586. Nej, Lars, der er ikke noget der tyder på at Tesla vil lave sine egne fabs... og "ikke noget" er en underdrivelse. Desuden er der stor forskel på chips. D1 og deres AI chips til bilerne ligger i den høje ende -- de bruger ikke helt de nyeste og dyreste processer, men det er tæt på. Deres MCU kræver også nogle ret ok chips (AMD64-kompatibel CPU chip fra Intel eller AMD + evt en grafikchip + nogle SRAM-chips + nogle flash-chips). De chips bilbranchen står og mangler er i den helt anden ende: det er små microcontrollere, hvor der er (midlertidig) mangel på visse af dem men hvor der findes alternativer der kan bruges i stedet. De kræver IKKE de nyeste og dyreste processer. Hvis Tesla skulle lave dem allesammen skulle de bygge adskillige fabs (evt under samme tag): superdyre high-end processer til D1, HW3, x86-chips, SRAM-chips, flash-chips ... plus knapt så dyre processer til alle microcontrollerne. Og de ville skulle mestre adskillige high-end processer samtidig: måden man laver SRAM-chips på er dybt anderledes end måden man laver logik på. Måden man laver flash-chips på er igen dybt anderledes. De dyre processer kræver nogle dybt specialiserede maskiner ("steppers") fra ASML i Holland. Der er lange ventelister på de maskiner og det tager ca et halvt år(!) at kalibrere sådan en maskine efter den er blevet samlet hos kunden. Det ville være realistik muligt for Tesla at lave en knapt så avanceret fab til microcontrollerne, men hvorfor skulle de, hvis de kan skrive deres driverkode om så den kan køre på andre microcontrollere som er nemmere at skaffe? Og det er rent faktisk hvad de har gjort... Du kan få en idé om chipproduktion ved at kigge på følgende youtubekanaler: Asianometry, TechTechPotato og ASML's egen kanal.

  4400.  @irtakus a short follow up on the Flynn effect… it is not as extreme as you portrayed it and there is zero reason to believe it will solve any of our immigration problems but the effect is indeed real. The obvious candidate reasons are better nutrition, less pollution/poison, fewer diseases/parasites, and better education/more books. We would expect the poor to be more afflicted by all four and we do in fact see a much stronger Flynn effect historically amongst the poor than among the middle class/rich. Longer schooling didn’t have much of an effect, though. It has also stopped in rich, industrialized countries. And even poor people in the Middle East and most of Africa have better nutrition and a lower disease load than middle class Europeans had a hundred years ago… There is a funny error source, though. Some IQ tests are more affected by education than others. Raven’s progressive matrices (which is nice because it is culture neutral and easy to administer) is very affected but most others show only a tiny effect or no effect at all. That means you have to be careful when you hear about a study that purports to show a strong recent Flynn effect: you need to verify what test(s) it used. We have very good data on the Flynn effect for Moroccan migrants to the Netherlands, thanks to Jan ter Nijenhuijs (which I probably misspelled). The first generation had an average IQ in the low 80’s and the second generation in the high 80’s… and I think it used Raven’s progressive matrices. So, not much hope of them reaching 100 anytime soon :(
