My understanding of quantum physics is weak and I have a serious interest in electrons. So when you're talking about spinors and electrons I kind of get the principle of a spinor concerning a 3 dimensional object like for example idk a miniature horse idol and how during a revolution it could revolver to face a direction opposite its original revolution but I imagine in any practical theoretical physics structure a particle to not be three dimensional and so surely they're not talking about the orientation of the particle itself, so could someone explain please? Discussion of other quantum particles is cool too.

someone explain to me what the fuck is a spinor.
I understand tensors, Clifford algebras and Lie groups but I can't understand what Wikipedia is trying to define. I don't really know much topology so I don't understand the double cover of the orthogonal group definition, trying to understand the algebraic way.

Is Lie Algebra worth learning, if your goal is to learn the most general / widest varieties of mathematics? Are the objects and concepts in Lie algebra applicable beyond modeling spinors and shit?
