Textbook in PDF format This popular undergraduate quantum mechanics textbook is now available in a more affordable printing from Cambridge University Press. Unlike many other books on quantum mechanics, this text begins by examining experimental quantum phenomena such as the Stern-Gerlach experiment and spin measurements, using them as the basis for developing the theoretical principles of quantum mechanics. Brief Contents Stern-Gerlach Experiments Operators and Measurement Schrödinger Time Evolution Quantum Spookiness Quantized Energies: Particle in a Box Unbound States Angular Momentum Hydrogen Atom Harmonic Oscillator Perturbation Theory Hyperfine Structure and the Addition of Angular Momenta Perturbation of Hydrogen Identical Particles Time-Dependent Perturbation Theory Periodic Systems Modern Applications of Quantum Mechanics Appendices
