The biggest misconception about spin 1/2

My website link: “If you rotate a spin 1/2 particle by 360 degrees, it doesn’t go back to its original state, rather you need 720 degrees”. This is only technically correct if you interpret the words “rotate” and “state” in the way it’s intended, and here is the video on what they really mean, and what this sentence is saying. ---------------------- Many people have talked about spin 1/2 before, but I do want to chime in because there are a few things that I myself am not satisfied with all the explanations. (1) I personally don’t like **any** “demonstration” of spin 1/2, aimed at demonstrating in some physical situations you need two full rotations to get back to where you started, like the Dirac belt trick / spinning your hand trick. This is simply because physically, you literally can’t tell the difference before an
