A <Stern-Gerlach experiment> separates atomic beams according to a component of their <magnetic moment> in a nonuniform <magnetic field>. For an appropriate two-state <spin> system, calibrated outputs distinguish the two <spin> <eigenvalues>; <Stern-Gerlach expectation estimation> explains how repeated fresh preparations turn channel counts into an <expectation value>.
