    Greta Thunberg

    I think It's bad rhetoric. blame the messenger and control the narrative so it's about a young woman, not climate.
  2. 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:

    Non inertial frames

    I was thinking about a high rate of acceleration more than high velocity. When the speed of light is discussed in Relativity, they always specify "in a vacuum when measured from an inertial frame of reference". I was wondering if there are any predictions of what velocity would be measured for the speed of light from a non-inertial frame.
  8. If you could get into a really fast centrifuge with a device that measures the speed of light, would you see different values for c? If so, would the measurements be both higher and lower than c or just one or the other?
  9. Wikipedia has some examples of "cramps to Amps" too. I'd be happy if i could just interface my stationary machine to trigger the next image from google street view so i could take a walk anywhere on earth.
  10. If you could define what you mean by void and real as in "real particles" it might help. Sometimes you say the void is filled with real particles and that is hard to understand.
  11. It sounds like you are conflating the measurement effect with Heisenberg uncertainty
  12. Why does a perfectly good detector fail, by your estimation, just because a funny shadow from a double slit falls on it?
  13. will you admit detection is a kind of observation?
  14. how can you test something that is unobserved?
  15. how do you make any observation without detection?
  16. Which is it? a quantum wave, or object
  17. Repeating yourself over and over while ignoring any contrary evidence is preaching, not conversation.
  18. So physics is a conspiracy to deny your genius, or you have misunderstood physics. After seeing your postings on this forum, i'll have to go with the latter.
  19. In the clock's frame of reference, shouldn't t`=tsub2 - tsub1?
  20. That still sounds like a plan to cross a bridge. I think it worked out okay for Bruce Willis, when he went to retrieve his fathers watch.
  21. "While you can" could be considered implicit in "to live". Life is a dangerous place. Speaking as someone who has failed once or twice at many things in life, yet still survives, i can say failure just means i need a better plan.
