I tried to split/merge a couple of threads here...hope I didn't do too much damage.
What is this experiment in which the definition of angular momentum fails? You can't keep making vague allusions to some nebulous "experiment" in which one of the fundamental conservation laws of physics breaks down.I am sorry to upset you, but I found an experiment that shows the currently accepted definition of angular momentum r x p is incorrect. That is why I was interested in knowing who defined angular momentum as r x p and why. Unfortunately, I have been unable to do it, so far at least. Anyway, I understand that, in physics, the experimental truth has the last word, and that should not be suppressed.
