@deepthought saidYou provided a lot of jargon that didn't explain anything. Try to give a concise explanation without so many terms that don't really explain much at all.
I discussed that in the second post on the first page of this thread.
Use the Feynman Technique.

Very roughly the mathematical structure of the theory throws up a quantity we call spin which is jointly conserved with orbital angular momentum.Since you've been using all these words you clearly understand it. The entire post was as free of jargon as is possible. Since you're so clever you explain spin to us.

@metal-brain saidWhat was wrong with;
Define angular momentum.

@metal-brain saidAngular momentum is a standard term, which you can look up on Wikipedia. I don't have sound on this machine, so there's no point in posting YouTube videos.

@deepthought saidI have. It didn't explain anything well. I will admit to not understanding what it means even after reading up on it, but I doubt anybody here understands it either.

Nobody has seen an electron so how does anybody know it is spinning? I think someone simply concluded something is changing direction and it is probably the wave function, but that is the wave, not the particle. Or is it? I don't think anybody really knows.
Has electron spin ever been measured? Is it purely a wave phenomenon?
@metal-brain saidAngular momentum is a standard concept in physics that is covered in a high school physics curriculum. If your knowledge of physics does not reach that level, perhaps you should grab a high school physics book, study the problems therein, and move your way up from there.

@metal-brain saidIn other words, you have the arrogant delusion that nobody here can be smarter than you so to understand something you don't. News; Some of us here DO understand it. If you don't then that's your problem, not ours.

Is it purely a wave phenomenon?Yes, in the sense that a classical analogue doesn't exist for point-like particles. I need to think about whether classical waves have spin. A better way of putting it is that it is a purely quantum phenomenon.

@DeepThought
Can you think of spin as just an angular momentum force field? What that force is I don't know. New aspect of magnetism?
@kazetnagorra saidWhat was the speed?

@deepthought saidThis rotation of the wave function is credited for magnetism when aligned. Doesn't this deserve more attention in physics than it is given?Is it purely a wave phenomenon?Yes, in the sense that a classical analogue doesn't exist for point-like particles. I need to think about whether classical waves have spin. A better way of putting it is that it is a purely quantum phenomenon.

@metal-brain saidMore than one of us has already answered that; Electrons have no rotational speed. Do you wish us to translate that "Electrons have no rotational speed" in less technical terms so you can at last understand it?
What was the speed?
