>>14272501One time a company stored a bunch of chocolate chips in a silo. They are irregular so unstable. A bump or shake in the silo would cause jumbling and moving for quite a long time. The heat built up. The butter and oil melted. Pretty soon a flash point occurred and the thing detonated like a bomb and blew up the factory. Spin's like that but instead of tangible objects moving, it's minuscule discrete ticks on a thermometer or voltmeters. Things interact with their insides and everything's doing it and they interact with the discrete interactions themselves.
Spin is a legacy term going back to emission theory. The electron does not spin like a top. Something tangible interacts using its complex internal configuration made up of spacetime dimensions as a medium. That's electromagnetism. That interaction itself also interacts. That's what we call spin.
There are an incredible amount of interactions going on all the time. Brownian interaction applied to things interacting with their internal configuration. They are very small but discrete. That's the real question is why they are discrete. My thoughts are it's what is needed to exist, to hold the rest of the universe at bay from absorbing all your energy or dumping all their constraints and squishing you into a part of something else.
