I’m talking about quantum spin. Let’s find out how chasing this elusive little behavior of the electron led us to some of the deepest insights into the nature of the quantum world.

Electron spin explained: Imagine a ball that is rotating, except it's not a ball and it's not rotating.

Physics: “For that to make sense…” Quantum Mechanics: “I’m gonna stop you right there.”

Finally an explanation of why you have to rotate USB plugs twice before they'll go in!

Basically, the Electron doesn't have Angular Momentum because it's spinning. It has Angular Momentum because yes. It just checked "yes" in the Angular Momentum option.

I really appreciate the determination to not dumb down the subject matter, even though most people (including myself) won’t really get it. There are dozens of channels that will explain quantum mechanics with flawed analogies and misleading visual aids for the sake of accessibility, but the real meat of quantum mechanics isn’t so easily digestible. Quantum mechanics is a confusing and difficult subject, and to present it otherwise is more misleading than helpful.

Spin is always explained the same way in Physics classes: "Imagine a charged ball spining But it is not a ball, has no charge and doesn't spin"

7:46 Physicists were excited, but only in discrete amounts, probably.

I feel like a good analogy of spin 1/2 is a mobius strip. The first time around you end up on the other side but go around again and you get to the beginning.
