Not a physicist but I did study a degree in it. Spin is absolutely a direction and absolutely related to angular momentum, since it's basically the angular momentum that you get when all the angular momentum we understand is removed.
There's a reason it's called spin! I think what you're trying to get at is that it can't be understood in the traditional context of an object spinning, but the way that you're saying it is wrong.
- likelynew 9y agoNo, ELECTRON spin is not exactly a direction, as in 3D vector. In every direction, it can be +1 or -1. It follows different transformation than a vector(wigner matrix for j=1/2 and 1). Expressions like direction |z> and |x> are not independent in this case. Photon spin is actually a vector, as with all spin 1 particle.
