  1. In my experience, undergrad intro physics classes require knowledge up through derivatives and integrals. You might see differential equations in derivations of the equations that you use, but you would not be asked to solve them, as such. You might use infinite series, parametric equations and/or polar coordinates, depending on what's covered. Diff Eq's was something learned for later, more in-depth courses in the topics covered in the intro course.
  2. Not only that, but there was the rise of "vampire" circuits in some devices, especially TVs - some part of it was always powered, to shorten the "turn-on" time. So even if the rated power went down, it may still use more energy because it's always drawing power.
  3. Observation, to be sure, but I don't see where consciousness enters into it.
  4. I think you mean absorption. Light doesn't adsorb to anything. And we really can't say this for sure, because we don't have the equations that say what happens. It seems to be what the solution is converging to in the limit of v approaching c, but those equations apply to massive particles.
  5. We don’t have the physics to describe what it would be like. It’s not a valid reference frame.
  6. Sounds like a job for…a search engine!
  7. If it's elastic it will rise to its initial height, unless there is rotation imparted to it. It's the inelastic collision that requires more information and analysis.
  8. A 16-ton weight has been dropped on the perpetrator
  9. https://lmgtfy.app/?q=types+of+login+security+tokens
  10. That doesn’t really address genetics, and some of their variables aren’t independent. Saying how many times some group has won some marathon, and also some other marathon really isn’t new information; the runners are probably largely the same group, and in some cases might be the same people year after year. Dominant athletes are going to dominate, but are outliers and not necessarily representative. That skews the statistics. (It’s like saying Big 10 quarterbacks have won 8 of the last 20 super bowls without mentioning that Tom Brady has 7 of them. It says more about the individual and less about the conference.) It also only mentions societal and cultural influences in passing. Some countries do well in certain sports because a higher fraction of the population participate and they start young, plus other factors, probably.
  11. To paraphrase Ian Malcolm, scientists can be so preoccupied with whether or not they can, they don’t stop to think if they should. It’s why certain independent permissions (ethics) are needed for some experiments. Science gave us nuclear weapons but science isn’t what tells us not to use them.
  12. ! Moderator Note You were working on establishing the premise of this little exercise, which you haven’t done. As I suggested earlier, you would/could be making the same mistake all over again. Regardless, you haven’t made any connection between the article and h changing other than wishful thinking, and that’s woefully insufficient
  13. ! Moderator Note We have requirements in speculations, demanding a certain level of rigor. We also require discussions stay on topic, and this thread was about G, not h If you have more than conjecture(i.e. more than what you have presented here), open up a new thread
  14. Conscious Energy has been banned as a sockpuppet of FreeWill
  15. Not sure why, but my brain completely skipped over that bit when I was reading.
  16. Nobody has claimed this to be true.
  17. It's how they are defined. If you had point with a finite length, you can make a point that's half the size. If you have endpoints a fine distance apart, you can choose a point between them. Keep doing so. The limiting case is that points have zero length. You aren't counting points when you do this.
  18. Why not? How much information is in the natural numbers? You need to rigorously quantify these things, rather than assert them. There are lots of infinities in physics, but they are described by math How many solutions are there for the principle quantum number for the Hydrogen atom (Schrödinger or Bohr solution; pick whichever one you want)
  19. I would think loss of arctic ice would be a significant contribution, since the water reflects less well than the ice. And, of course, light not reflected is being absorbed, contributing to heating.
  20. But that doesn't limit the math. You seem to be insisting that it does. Your thread title is all about math and nothing about physical things.
  21. Some kind of epoxy or resin might achieve this. Soft (possibly liquid) until it’s cured. Probably ends up harder than sealing wax
  22. Numbers don’t physically exist. But these aren’t the same thing. A volume of spacetime is not the same as the points inside it.
  23. ! Moderator Note Is a digital signature sticky? Can you prepare a small amount for obtaining a relief pattern to yield a negative? No? Then this is off-topic.
