If energy to has to be conserved(likely, but could still be wrong)
Then if you do a bunch of math vs what is observed, you can guess where the energy is going

Just don't trust whoever writes the interpretation to make sense of that, or that they even understand the argument being presented

Why don't you just read up on quantum mechanics / field theory?

>>16703531
I've been doing that. I understand that spin is a property like mass and charge which works in mathematics. I understand that electrons and positrons aren't really "negative" or "positive", they're just 2 types of charges we call that. I can understand that "spin isn't really spinning". So far so good. It's the fact that "it's still angular momentum thougheverbeit xd" that confuses me.

This effects show that angular momentum can be imparted onto things through electromagnetism, I still don't get how a literal probability cloud that isn't spinning can have "intrinsic angular momentum".

In modern conception, "angular momentum" is the conserved quantity that you get from rotational invariance (see Noether's theorem).
However, for a field with spin, a rotation doesn't just transform the spatial coordinates, but also internal coefficients of the field itself. You can see this in classical field theories as well (if you rotate a system that has an electromagnetic field, the field vectors now point somewhere else).
So the conserved quantity is the sum of the spatial part (the "orbital angular momentum"), and the internal part (the "spin").

Spin exists via Stern Gerlach
Einstein de Haas effect shows flipping spin causes electron to literally rotate
Barnett effect shows rotating electron can change its spin
What the fuck would you conclude, troglodyte?

you tried

>it's not spinning
It is spinning, you cant see it because electrons are tiny
They spin
They also cant stop, tho the direction of spin can change
