Quantum physics professors explaining spin be like: "It's simple! Just imagine something that's completely unlike anything you've ever experienced!"
Particle spin is that magical quantum property where physicists named something after a familiar concept, then immediately clarified that it's absolutely nothing like that concept. It's not actually spinning, doesn't behave like spinning, but hey, let's call it "spin" anyway because physics wasn't confusing enough already!
No wonder students leave quantum mechanics lectures looking like that bottom LEGO face. Schrödinger's cat is simultaneously alive, dead, and completely done with this nonsense.
