  1. Sorry if I'm confused but I think the analogy is 97% are saying the plane won't make it and you are saying we should believe the 3% who claim everything is ok.
  2. I was joking about doing an infinite number of steps in a finite amount of time because the number is a repeating decimal with a rounding error. or is it?
  3. The Tweets are part of his public record so he could probably argue they are notification. Seems like he still deletes them occasionally so he has it both ways - official AND just kidding, depending on what's convenient.
  4. I have no love for authoritarians and won't grieve at their passing. That is why I don't feel comfortable with the President unilaterally ordering assainations
  5. After years of British and American destabilizing Iran. I just think it's strange that Bill Barr (forgiver of Iran-Contra crimes) is A.G. while the President is assasinating foriegn nationals. I never nderstood what Trump meant when he says "great". Now I think I understand better.
  6. Maybe this will end when "greatness" is restored. Or whatever "greatness" means to commander twittervent.
  7. then hopefully you can do prime factorization quickly 1020/1000 2 * 510 / 2 * 500 2 * 255 / 2 * 250 5 *51 / 2 * 125 / 5 * 25 / 5 * 5 51/50=1.02 1.2105263157894736842105263157895 / 100000000000000000000000000000000 =?
  8. Why not just write "1.05" as "105/100" and simplify the fraction? I'm not sure if that's what you are asking, but if it is, from there do a prime factorization of the numbers and eliminate common factors

    I think It's bad rhetoric. blame the messenger and control the narrative so it's about a young woman, not climate.
  10. Should it be "approaching zero seconds" to avoid the wrath of Heisenberg? Is it okay to have fuzzy position info when we're concerned with velocity?

    Non inertial frames

    I think i remember that thread. I can't remember if it got into shooting the light across the diameter. At high enough angular velocity would the beam hit the detector directly at the other side, or would it appear to curve (from the rotating frames perspective)?

    Non inertial frames

    I was just looking at the wiki for rapidity and realized this is about where I got stuck on vector calculus. Just a quick question: if y=arctanh x, does that mean x=tanh y ? edit2:Another quick innumeracy related question, hyperbolic trig functions map points on a hyperbolic curve to points on the x,y axis the same as trig functions map points on the unit circle to the x,y axis? Thanks

    Non inertial frames

    Does this mean c might be the same value but velocity vector has changed? Edit: Velocity vector sounds redundant. i mean the magnitude of c is the same, but the trajectory is different?

    Non inertial frames

    I see hints that the velocity of light is different than c in non-inertial frames, but not how it would be different. Here's one:
