Quantum spin. Electrons aren't really spinning, right? But why do we call it spin? I know it has something to do with angular momentum. What are the possible values? Is it a magnitude or a vector? Is there a reason we call it "spin" instead of "taste" or some other arbitrary name? How do you change it? What happens to it when particles interact?

The complex exponential term in the equation of the electron is called Zitterbewegung, and it may be interpreted as a spinning of the electron at speed of light in the complex space.
