  1. If it wasn't for the log tables Newton wouldn't have formulated the orbits. Shows how science builds on itself.

  2. He's so right about our terrible math in K-12 teaching. I graduated 2001... all through it seemed to just repeat and was way slow. And the teachers weren't that great, some didn't even understand the material themselves.

  3. Isn't weird how gentiles smell musty. Both girls and guys over just a few hours after taking as shower.  Kind of a funny fishy/cheesy/bo stink odor.  Stinky.

  4. Mr CJ, I agree with a literal use of 0.  But using it for in equations you discover something interesting about 0, that it has properties that have discrete meanings that have uses: undefined and indeterminate.   Negative numbers do provide lots of understanding that you couldn't do if you took an absolute value, it allows filling geometry with dimensions which dimensions do exist.   Just as complex numbers literally defined are just a place holder, but that place holder works. Complex numbers reveal more of reality.   Infinite sequence segments numbers are also another method that provide detail about physical reality.  Such properties do appear to exist. Our literal absolute number line is only useful for basic everyday uses and even some everyday uses without accepting negative numbers you've just made your life more difficult when coming to liabilities and credit that must be paid sometime in the future. You're just making life harder not to accept these numbers in a more richer way. Otherwise why even bother with real numbers? 1 apple 2 apple real numbers aren't real in that case of literal numbers because each apple is slightly different from another apple.  Even atoms while made of the same amount of protons and neutrons, may have a different energy level in the electron orbitals, etc. And that's not really bringing up all the quantum stuff that describes super positioning, entanglement or uncertainty principle with the wave and particle duality that atom sized objects tend to have. So there isn't any reason to take any of the numbers flat literally. Otherwise you're just making life harder not simpler.   What's important is knowing when to know when such numbers are significant or not to whatever it is you're trying to do with them.

  5. But it is useless when trying to determine anything as nothing is undefined. Trying to solve an equation, calling x/0=0 doesn't get you far. When you can say its undefined and discover yes Ohm's law is worthless now at 0 resistance. But further experimentation and understanding of electrical currents especially those under critical temperatures that provide 0 resistance, you can work with it. And realize there is a set amount of current in your wire if it gets quenched and how much sudden resistance with current and voltage over the load causing the quenching will happen. Important to know how big a boom if any will happen to engineer methods to deal with such an event.  You have take the consideration of the Meissner effect and London equation.  Because we know Ohm's Law isn't a law, it isn't correct under all conditions. Its condition dependent, it just happens to be easier. Same thing is likely true with Einsteins theory.  There are missing parts that aren't correct or just missing.  Seeing an undefined lets us know  this immediately.

  7. Not if its an algebra equation. Its undefined and means your relationship to the equation is useless as it doesn't define any required terms for use.

  8. People of the future starving from famine due to climate change and utter collapse of economic-political structures using what little energy they have to check a hard drive from some servers for methods of making nitrate fertilizers, instead they stumble onto this.  Not only will they already hate us with a passion, adding insult to injury they'll stand stunned out how more incredibly vain and frivolous than they even imagined: square or cube root birthdays... one of them will want to know where the cemetery is, and specifically one of these guys in the video so they can unload a doody in their skull.

  9. The equation of Einstein breaks down. Math lets us know by giving us an undefined divide by 0. Same happens with many equations like Ohm's Law.  0 Resistance does happen, but Ohm's law poops out undefined current. So you have to use other models and methods to describe details of what's going on and harness those events to make something useful.

  10. ***** The law breaks down because it isn't the most accurate model on exactly what is going on. Its wrong for many other conditions. Ohm's Law is only called a law for historical reasons, and since now many stipulate the conditions, its okay to describe Ohm's Law as a Law, but not a model or theory. It incorrectly describes current, voltage, and resistance relationship in conductors for all conditions. It doesn't even work for diodes. People still use it because for normal everyday electronics tend not to be superconductors and aren't working with diodes and other components that violate Ohm's Law.  Or they'll switch away from Ohm's Law. Because it isn't accurate for their use. As for electrical resistance, at the critical temperature, there really is 0 resistance in that material.  While the flaws and vibrations of the atoms do exist, the electrical resistance is 0.  So far tests show even after 50 years the current is still preserved. The atomic flaws and vibrations appear not to interact with the initial current being induced into a superconducting circuit, those flaws and vibrations don't provide any resistance to the current. And current can store forever in the closed system and not violate thermodynamics because no new energy is being created.  Newtonian physics meets Einstein Relativity. One model does good enough job for most things currently, but the other is more accurate and must be used for those conditions requiring its use because Newtonian physics is fundamentally, as a model is wrong for all conditions, Einstein does all of the conditions Newtonian physics allows plus more, so its a more accurate model.  Same with Ohm's Law vs BCS Theory, London Theory, etc. http://www.supraconductivite.fr/en/index.php?p=supra-resistance-supra

  12. Observation that backs up something like a big bang means its not really magic. Expansion does seem to have occurred. What we don't understand is what caused the expansion. Borrowing energy from quantum vacuum seems to be plausible. But we don't know yet. We will know should we continue to experiment and discover more. Much more plausible than magic tricks from any religion that has time again proven complete rubbish and incorrect.Science adjusts and admits error, missing observations, etc.

  13. Infinite isn't just big. It never ends in size. Therefore it is undefined. Either in size, time, or scope. It is the opposite of 0. You must use relation to what 0 is to make sense of 0. You have to do the same thing with infinity. Resolved. Lets move on. :) LOL!

  15. But you're all to busy just going along with our wrongness. So how can we decide we're wrong, if you all just go along with it. Makes us feel like nothing to fix. Oh well. I learned the short hand way. So I'm use to it. Even though the long hand way makes more sense terminologically.

  16. But magic as in fiction and fantasy is a lot of fun. It can spark creativity. And it does exist within the constructions of our own minds. Taken with a grain of salt, magic can entertain and provide ideas that may lead to actual discoveries of what actually exists. But too much can fill you up with nonsense and make you really stupid. Like watching too much TV or too much reality shows. Your brain turns to jello and your body become weak as you turn into couch potato.

  17. No magic. Magic is make believe (dishonest). We don't know yet. Believing in magic and if taken too seriously can hold back discovery of what actually is occurring. So no magic is not a possibility. If something exists it cannot be called magic. Borrowing energy from vacuum of space is not magic, it is a fundamental property of the universe. But only an idea, we see this borrowing in very small time frames at quantum levels right now. It's just a possibility for the big bang's initiation.

  18. I think what he means, infinity cannot exist in physical world. But it does exist as a construct we have created, and any other species out there in the universe. We have yet to observe true infinity. Even the use of infinity in worm holes. Physically black holes have a finite mass. Density may no longer play a role physically when a certain finite density is reached. Mass may just overlay in the same space causing a double mass/space occupation. Again no physical infinity.

  19. My brain is wired pretty stiff when it comes to numbers. I see them as just numbers. No colors, or fancy shapes, or smells. Just a quantity of something. Can be music in beats or bikes or size quantities. But as numbers by them selves. They're just numbers. A quantity of something. :( Same as letters. I think of them in terms of words or names that they can start with. But nothing interesting :(

  21. I'd be a fictionalist. I think numbers are a nice alphabet for us to make sense of the world. But they're not true because of themselves. And just because they're successful doesn't make them true. The fact is, they're all slightly off on exacts. In nature there seems to be no exact. And you can see this very clear in quantum mechanics.

  22. Well for those who read comments before playing or have to watch commercials: What can I say. Its got shouting 0:30 , secret limits on how long he can go at 1:01, at 1:11 we know its fun, 69! is the largest he can get 2:06 , at 2:59 beyond 69! is too much for his pocket cruncher to take, and finally we learn 69! and other such things leads to more exotic things 3:11 So get ready for a passionate ride in education!

  23. I think, at this point, concerning your final question "what made nature" it is your turn to use your brain and discover how nature works. You'll be amazed at some of the simplicity that has been discovered. And the complexity is just based on very simple structure. So in the end what made nature like the big bang, was probably something as quaint and insignificant as some fluctuation within itself. Like water interacts with itself. No magic though. Sorry.

  24. No, the observable universe is calculated by light we're able to see-- the cosmic radio background noise we see in all directions-- the strength of the photons and all have worked out to being 8.8 x 10^26 meters to be the diameter of the observable universe. A possibility that more of the universe beyond the observable: 1) universe hasn't existed long enough for the light to get to us. 2) expanding universe is expanding faster than speed of light and may never observe that part of the universe.

  25. But you can use your point to put infinity in some context. With infinity you essentially make probability meaningless. Even if more often then not the copies are of stellar gas, vacuum, or other non-specific things, but because infinity is never ending, at some point you would eventually cross where the macro and micro converge and have your copy universe. And because its infinite and it happened once, you'd run into another copy again and again infinitely. Why infinities get really insane.

  26. We're use to UK measurements as they are also apportioned into everyday useful portions thus easy to conceptualize than metric lengths, volumes, and weights. But we don't use them in medical or science as much, because they're a math pain. We use metric then we convert our solution into the UK system for conceptualizing :) I love my country. We're odd: slightly lazy but in being lazy do more work in the end.:) Land of the free, Home of the brave, and birthplace of the ironic.

  27. That ironic, could be substituted for moronic too.

  28. Ohhh we're all the beast. And Carbon 12 is 98.9% of all carbon on earth. We're 98.9% evil. All carbon based life forms are. MOOOHAHHAHAHAAA!
