Why Do Electrons Spin? Feynman's Mind-Blowing Answer

Описание: You want to know why electrons spin? You want me to tell you they're like little spinning tops—tiny balls rotating on an axis. That's the picture in your head right now. And I'm telling you: they're not. Not even close.

The electron isn't spinning. There's no axis, no surface moving in circles. The word "spin" is a trap—a leftover label from a century ago when physicists discovered something they couldn't explain.

The honest answer? Electrons have spin because the structure of the universe requires it. When Dirac combined quantum mechanics with special relativity, spin emerged automatically. He didn't put it in. He couldn't take it out. Spin is bedrock. The chain of "why" ends here.
