how do they measure the rpm of subatomic particles?

>>16817856 (OP)
Why do you think they do?

how can they tell that one particle is spinning half as fast as another if you can't put a tachometer on it or anything

>>16817865
Usually by observing atomic transitions and reasoning with angular momentum conservation and selection rules.

>>16817865
Have you read the wiki page you shared? They explain the experiments, results, and interpretation.

"Spin" doesn't literally mean the particle is spinning any more than a "color charge" implies quarks have color.

>>16817922
so why call it something that its not?
must explain why theres so many troons in science these days

>>16817922
I like the pretty yellow quarks.

It is not literally spinning but exhibits properties as if it were. Brainlets like you can't seem to comprehend metaphors.

>but exhibits properties as if it were
soooo its spinning, if everything says its spinning then its spinning

>>16817951
Because its an analogy. We call it "colour charge" because there are 3 possible charges (6 including antiquarks), the same way there are 3 primary colours (and 3 inverted primary colours). There are no pre-existing words or phrases to describe concepts like colour charge or quantum spin, so scientists come up with new terms.

iirc particles dont move in circles lmao

they move randomly like GBM if you're familiar with stochastic processes in finance you fucking retard

They do everything today with accelerators, the classical experiment is the Stern Gerlach. Not sure how accurate it measured spin, it was really only to prove spin existed and had two values only
