> Oh… dont tell me Quantum Spin just called Spin because it’s a Spinor rather than something actually metaphorically spinning?!
That's a great way to understand them if you are already comfortable with the algebra of spinors and spin groups, but it doesn't short-circuit the history—spinors were so called after quantum spin (https://en.wikipedia.org/wiki/Spinor#History), and I believe that was so called because, yes, it was envisioned as something at least conceptually spinning.
I've tried many times to go through Modern Algebra texts, and so I on-the-surface get that it's an algebra of sorts.
When I have enough time I'm going to finally go through mathacademy.com, because I think it really does suck not knowing advanced maths but want to do the hard sciences
