Spin is preserved, and you need to rotate fermions a full 720 degrees if you want to get back to where you started from. So what precisely happens with a *pair* of

Why does an electron spin 1/2 need two full rotations instead of one to return to its original state? - Quora

Spin is preserved, and you need to rotate fermions a full 720 degrees if you want to get back to where you started from. So what precisely happens with a *pair* of fermions at 180, 360 and 720 degrees of rotation? If they start with opposite spins? - Quora

Why do drawings of electron spin suggest up/down is just a matter of rotating the diagram 180 deg. What actually distinguishes + from - spin apart from orientation. Are they mirror images? - Quora

Why are baryons both hadrons and fermions? - Quora

Spin-1/2 - Wikipedia

What is angular momentum or spin of an electron? Why is it called spin if it has nothing to do with actual rotation? - Quora
