James Hartle has died. A few years ago I had the pleasure of using his text to teach an undergrad GR course. -
PeroK reacted to Mondayman's post in the thread ChatGPT spin off from: What happens to the energy in destructive interference? with
Skeptical.
Not entirely true. I used to use ChatGPT for hockey/American football trivia and had to stop because it simply sucked and couldn't... -
PeroK reacted to Astronuc's post in the thread Google DeepMind, AI/ML and ALPHA-fold with
Informative.
I came across a video regarding the use of AI/ML to work through complex datasets to determine complicated protein structures. It is a... -
PeroK replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.Not really. You just need a synchronization procedure. That defines the 1wsol. There are no physical assumptions, per se, in defining...

PeroK replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.We might as well assume that ##t[A1] = t[B2] = 0##. When A receives the signal back from B, the clock reads ##t = \frac {2L}{c}##. A...

PeroK replied to the thread B Is a table levitating possible, even at a minuscule probability?.If you do a computer simulation of coin tossing, you might get 30 heads in a row (that's 1 in a billion), but probably not 50 heads in a...

I think you can be sure of the distinction between genuinely possible things, and speculative things for which we have no evidence...
