Hold up! Omg, can someone who’s done physics chime in please… whenever I’ve looked at GUT etc, I’ve always seen U(n), SU(n), but never knew what they were - are they what’s referred to in this article? Is that just the Unitary Group and Special Unitary Group??! All that time I thought it was all impenetrable but it’s just algebra?
Omg wow... the theoretical physics I’m talking about is just quaternions and Lie Algebra isn’t it? Oh… dont tell me Quantum Spin just called Spin because it’s a Spinor rather than something actually metaphorically spinning?!
Please chime in if you know what I’m talking about and can confirm this or shoot it down.
