Know of any good visualizations of this? Because I have no idea what something has to look like in order to be spun 360 and be inverted from where it started. That has to be some 4th spatial dimension tesseract shit, surely. That breaks my brain!
eta: saw @rockerface@lemmy.cafe posted spinors which has some great illustrations... surprisingly less 4th dimensional than I was expecting, but still brain breaking
There is the famous "belt trick", plus this PBS Spacetime really explains it well!

All macroscopic examples of spinor involve an object attached to the exterior world. Electrons having spin 1/2 therefore imply that they don't exist "by themselves" and are embedded in a larger field.
I'm not sure whether that would be the electron field of the electromagnetic field, or maybe all of the fields?
I like this one.
