Lecture 4 of MIT's 8.05 Quantum Physics II (Fall 2013), in which Barton Zwiebach builds the machinery of spin one-half: its states and operators, the properties of the Pauli matrices, and spin states along an arbitrary direction, the general form of this session's cos²(θ/2) rule. Best watched after the lesson; it assumes the bra-ket notation of chapter 14.

MIT Physics Instructional Resources Lab · Jerrold R. Zacharias
A 1967 college physics film featuring MIT's Jerrold Zacharias, a molecular-beam physicist who co-authored Rabi's 1938 magnetic-resonance paper. As you watch, compare the apparatus with section 2's: an oven, collimating slits, shaped magnet poles and a record of where the atoms land.
Demo · University of Göttingen
Lehrportal Uni Göttingen
A short film of the Einstein–de Haas experiment as it is presented in the University of Göttingen's Experimental Physics IV course: the effect in section 3's callout. Watch for the sample's twist when its magnetization flips, the sign that spin is real angular momentum that can be traded for the ordinary kind.

MIT OpenCourseWare · Barton Zwiebach
A 17-minute 8.04 segment in which Barton Zwiebach treats a photon's general polarization state and spin states. Keep section 5's contrast in mind: polarization follows Malus's cos²θ, but spin odds follow cos²(θ/2), because opposite spin directions are perpendicular state arrows.

MIT OpenCourseWare · Allan Adams · 2013
Allan Adams' celebrated course starts from superposition and the experimental facts, builds the wavefunction, operators and the Schrödinger equation, then tours scattering, hydrogen, identical particles and band structure before closing on entanglement and Bell's theorem. Calculus and a little linear algebra are enough to keep up.
Course · Oxford
University of Oxford · James Binney · 2009–10
James Binney's Oxford course, given over Michaelmas Term 2009 and Hilary Term 2010 and built on probability amplitudes and Dirac notation from the very first lecture. Highlights: tunnelling and radioactive decay, the EPR argument and Bell's inequality, spin and the Stern–Gerlach experiment, and a full treatment of hydrogen.

The Science Asylum
Nick Lucid of The Science Asylum retells the 1922 experiment at an ideal pace for a first look, including the twist that the experimenters had detected spin years before anyone knew spin existed. As you watch, hold the classical expectation in mind, a continuous smear of deflected atoms, and ask yourself why two clean stripes were such a shock.
