Pauli exclusion Memes

Electrons in the 1s orbital playing quantum musical chairs! The Pauli Exclusion Principle states that no two electrons can occupy the same quantum state simultaneously. Here we see two electrons trying to have the same spin state in the same orbital, and... *poof* - nature says "nope" and they repel each other. It's basically quantum physics saying "find your own spin state, buddy, this one's taken!" The ultimate subatomic social distancing.
