# Quantum superposition and spinors – a saga of electrons

[What’s changed in the last ~100 years] A recent Scientific American article reminded me that quantum spin underlies the stability of matter – without which there’d be no life. But the article prompted another dive into the “mathematical machinery” describing the quantum state of a single electron or a single photon. The Stern–Gerlach experiment established… Continue reading Quantum superposition and spinors – a saga of electrons
