>to rotate once...you must le rotate twice!!!
modern physics is a joke

spin is to magnetic moment as sign of charge is to electric charge. wow, so mysterious. so difficult.

Explain how to derive all unitary irreducible representations of the Lorentz group. You need to do this to understand Spin

This has always been a joke. The trick doesnt prove anything. The plate trick is just as stupid.
Yes, you have to do a double rotation to go back to zero, however there is no obvious connection between that and spin. To understand spin you should just understand the mathematics of it, these visual tricks alone are useless. You are just supposed to look at them, be impressed and say "now i understand spin" but you dont, because electrons are not twisted belts so the knowledge of the trick doesnt directly apply

Hehe, I'm reading that chapter right now :)

OP here. Turns out I was wrong. I don't know shit about spin. I believed myself to be smart for understanding representations of the spin group on a vector space and the double covering. It seems spin is much more fundamental with a lot of algebraic topology and differential geometry involved. Guess I gotta read the whole book on spin geometry.
