At some point you’re stuck with a bunch of equations that work and the only way to make progress is to try to interpret the equations. > Electrons aren't little hard balls, which is why they don't rotate, and this is why spin isn't some huge mystery. This doesn’t clarify spin at all. Spin is actually incredibly weird and anyone who writes it off probably doesn’t understand what’s interesting about spin quantization, spin/angular momentum noncommutativity, fermions obeying SU(2) instead of SO(3) rotation characteristics, etc.
