In the quantum world, particles are divided into unsociable individualists and sociable party-goers — that's what the spin–statistics theorem states. A particle's character is rigidly tied to its spin: half-integer spin — 'don't like neighbors' (fermions, like electrons), integer spin — 'the more the merrier' (bosons, like photons).

How it works

The theorem explains why electrons in atoms occupy different orbitals (Pauli principle), and photons can accumulate in one state (laser effect). It is also responsible for the stability of white dwarfs (degenerate electron pressure) and for superconductivity (Cooper pairs as bosons).

💡 If electrons were bosons, all atoms would collapse into uniform lumps, and the Periodic Table would disappear.
(-1)^{2s} = \begin{cases} +1, & \text{integer spin (bosons)} \\ -1, & \text{half-integer spin (fermions)} \end{cases}
s is the spin quantum number (eigenvalue of the spin operator in units of Planck's constant ħ ≈ 1.054571817×10⁻³⁴ J·s); for bosons s = 0, 1, 2, … , for fermions s = 1/2, 3/2, … . The +1 sign denotes symmetry of the wave function (Bose–Einstein statistics), –1 denotes antisymmetry (Fermi–Dirac statistics).
