Spin-Statistics Theorem

Intuitive

Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.

Abstract

  • The standard reference is the book PCT, Spin and Statistics, and All That by Raymond F. Streater,

Why is it interesting?

The spin-statistics theorem tells us that there can be never two identical fermions in the same state (they anticommute), while there can be arbitrarily many identical bosons.
