The Stern-Gerlach experiment is a Book I topic in the Quantum Collection. It demonstrated that angular momentum components are quantized by sending silver atoms through an inhomogeneous magnetic field and observing discrete beam splitting. In modern quantum mechanics the experiment is a standard model of spin measurement. A spin-1/2 particle prepared along one axis gives probabilistic outcomes when measured along another axis. The experiment connects spin, magnetic moments, state preparation, projection, measurement back-action, and the departure of microscopic systems from classical continuous variables.
