  1. that's why you shouldn't use antibacterial agents as a matter of course. it means that they'll soon be useless against the ones that survive.

  4. Kind of. It will be calculated via the Planck constant measured on the basis of the existing kilogram standard. However, once they calculate the constant, it's value will be fixed and the new kilogram based on that.

  5.  @InanisNihil  i'm not talking about evolution, i'm talking about safety. i'm saying that we should not use antibacterials in everyday life because the ones that survive are those that have a genetic resistance. over time, the resistant strains will become more numerous. as a result, the antibacterials will become useless. it is better to reserve them for situations where safety is essential, such as surgical environments.

  7.  @dabearzs  i wasn't thinking of antibiotics. they're quite a different thing, since they have to be safe enough to be ingested. so you're saying disinfectants won't cause that problem? that would be good news. have you got research to back it up? hey, new treatment for pnuemonia: put disinfectant in a nebulizer! (disclaimer: don't ever do that, it's a joke!)

  9. Veritasium Good on you for the set up and the synched video. It was great to watch. Actually I experimented with a friend of mine when we were kids and we came to the conclusion that if the coriolis force had any effect, it was negligible compared to other influences. We didn't use dye though, which would have been necessary to detect a small effect like that.

  10. Diepieche Ehciep im guessing but prob'ly the closer to the equator the weaker the effect so at the equator it's not noticeable.
    2
  11. +Veritasium um i did notice that there was a mismatch betweeen audio and video, although it only barely noticeable and wasn't annoying. i've been making music videos lately synching animation and audio, so maybe i'm more used to looking out for mismatches. also, fyi when you first played the circle with the white flash, i did not see a flash, but i saw it in later repeats.

  12. oh yeah that's like in the lion king, the circle of life.

  13. DreadX, maybe that's it (the outer rim). Very subtle ... but then this is meant to be a riddle.

  14. Human population has been on an increase for thousands of years. We've kind of assumed this will continue, but at some point it will grow beyond what the earth can support and will decline. So what is the value of r for human population growth and will it reach an equilibrium or will it oscillate? Since the oscillations are probably in the order of millennia, how does climate (both man-made and natural, including ice age cycles) affect this?

  15. IIRC the four computers on the space shuttle had three running the same copy of software developed by NASA and the fourth had independently written software with equivalent functionality. One of my students gave a presentation on it. But you won't believe it - as he was giving the presentation, a shuttle pilot walked in and joined the discussion! That was a bleeding amazing experience!

  17. I think it's because there were thousands of applicants to begin with. If only 0.1% had sufficient skill and determination, there would still be too many to fill the limited vacancies. The only distinguishing features among the best of the best were factors beyond their control. Even then, some aspects of skill and determination are traits you're born with. You have to develop, train, and put in effort, but there are elements of luck there too.

  20. I think what would revolutionize education is finding a cost-effective way of identifying how each child best learns and tailoring their educational experience to that. This is because people learn in different ways. I can learn by picking up and reading a book, even when it comes to manual skills. Other people need hands on experience and figure it out themselves. Others do best with a guiding hand. Also, while in my experiences (with me and with my kids) most teachers I've met are dedicated, inspiring and caring, there are some that are not. Also, some children simply don't have the motivation to learn, that is until it's too late and they regret. Now tackling those problems would also be of immense benefit.

  21. the average of your speeds is (v1+v2)/2, but the definition of average speed (at least from high school) is total distance over total time, 2D/(D/v1+D/v2)
    1
  22. If you had two cars simultaneously travelling at v1 and v2, you'd say their average speed is (v1+v2)/2, the average of their speeds. So I agree it's a matter of definition. But given that this is meant to be a "riddle", I think he means the average speed over the total course, not the average of the two speeds, in which case achieving 2v1 is impossible. With the "average of the speeds" definition, it's a simple calculation as people have shown and there's nothing much to it.

  25. you've sort of contradicted yourself. on the one hand the initial age-based model you said was wrong but then you ultimately concluded with an equivalent age-based model.

  26. +Brian Lynch I think the experiment is deliberately limited to people you directly. Based on the results of that experiment, it would be nice to compare with a similar experiment if you also include people you are commonly in touch with over the internet and compare the difference. You would expect it to be shorter since you are adding more connections, but would it make a real difference and if so how much?

  27. actually this doesn't make sense. a stationary positive charge experiences no force. by your reasoning, however, the moving electrons would be contracted, leading to net negative charge, so the positive charge would be attracted.

  28. how did newton ever figure out the third law anyway? it's not obvious.
    1
  29. Your Waifu Sucks You're joking, right?
    1
  30. Your Waifu Sucks "will only come to rest if there's an equilibrium in forces" ... no, if an object is moving unifromly, then there is an equilibrium in forces. if it then comes to rest, a net force must have been applied to slow it down. What you have said violates the first law. "another force cancelling the force you applied" ... if an object is at rest and remains at rest, then there may be two equal and opposite forces acting on the object, but these are not what is in scope in the third law. The third law says when A applies a force to B, then B applies a force to A, not to itself. "means an object also applies a force in the opposite direction so it won't move" ... no, object B experiencing a force from A will apply a force back to the other object A, not to itself, so that's not what is cancelling it out. Firstly, whether an object is moving or at rest makes no difference to any of the laws. What matters is whether its motion is changing. I.e., getting faster, slowing down or changing direction. Then you can say that there is a net force. Secondly, a moving object may experience two equal and opposite forces that cancel out, just as much as a stationary object can. In that case, it will continue its uniform motion. In such a case, say A and C both apply forces on B that cancel out, then the third law says that B applies a force on A and also B applies a force on C. Does that make sense?
    1
  31. Your Waifu Sucks Maybe you think you're saying it but I can't see how you are. "applying a force on an object will cause it to apply an opposing force" -yes, correct- "hence your velocity is constant" -incorrect-. The velocity will be constant based on forces acting on the object, nothing to do with the 3rd law, at least not directly, only indirectly. Following what you're saying, though, and returning to my original question, if you have an object lying on a table, it experiences gravity but it's not moving. therefore it must be experiencing another force. if gravity is making the object push down on a table, then 3rd law says the table must be pushing back up, thus the obejct doesn't move. Still, it would take a genius to work out something like that. I guess Newton was a genius.

  34. um um i haven't read the other replies but so far there's no evidence of alien life, but there is evidence of God. of course if you count angels as "alien life", then there is evidence of both.

  35. ***** well there could be one difference. no one as far as we know has had experience of extraterrestrials. however, people have had personal experiences that have led them to believe in God. but yeah considering that we now know that there are billions of galaxies each with potentially billions of planets, you can't categorically say there could be no life. you can prove life exists by finding it, but it's impossible to disprove. all you can say is that we don't know and possibly we may never know.

  37. +Jason93609 I think that he would agree with what you're saying, but the point he's making is a bit different. Given what human psychology is like, it's better to teach good science to the masses in a way that people will take it in readily rather than in a way that takes lots of education and training.

  38. +spaceface3122 Have you repeatedly tried to prove this result you're claiming? Or are you just mentioning one anecdote? If so, Trump will applaud you.

  42. it's a highly controlled environment with little opportunity for utilizing their environment in novel ways. suppose they evolved hairs or eyes or ears? what advantage would that be? just a waste of energy and makes them less suited.

  43.  @farahat9  just growing bigger or faster at absorbing glucose is just microevolution, adaptation in a limited way to their environment. the only aspect mentioned that might be called genuine evolution was that they could assimilate citrate since it's a new function that wasn't there originally. actual speciation has apparently been reported but it's extremely rare. i don't think the world has enough evolutionary pressure. give it another 50 or 100 years with climate change and we might get a better idea of if/what/how it happens - well, those of us who survive will.

  44. The format is fine, only the lower audio quality plus foreign accents made it hard to follow what they were saying. Sciencium? I thought you gave up on that so I unsubscribed. I don't think you need two channels anyway, just post it all here.

  45. according to wikipedia, there are two fagenbaum constants, 4.67, the ratio between bifurcation intervals presented in this video, and 2.50, "the ratio between the width of a tine and the width of one of its two subtines" which I don't quite understand without a diagram ... https://en.wikipedia.org/wiki/Feigenbaum_constants

  56. This is just poor semantics. For a start, you can't judge probabilities from one instance of an experiment. Secondly, it depends on what the question is, and it has deliberately been poorly phrased. If you repeat the experiment many times with a fair coin so chance of heads is 1/2, then she'll be woken up twice as often on half the experiments, so if she answers heads she'll be correct 1/3 of the time. Note that the 1/3 answer relies on the probability of heads being 1/2. If it's not, say heads is 1/3, then she'll be correct only 1/5 of the time.

  61. unfortunately we can't test your hypothesis because doing experiments on animals designed to deliberately kill most of them would be unethical.

  62. The "right" answer depends on what the question is. The answer of 1/3 actually depends on the answer being 1/2. If the coin is not fair, then both numbers will change, not just one of them. The answer of 1/3 only comes up because she's deliberately being woken up twice as often in one of the outcomes.
