Principles of Quantum Mechanics,During the years 1925–1927, quantum mechanics took shape and accumulated successes. But three persons, and not the least, addressed the question of its structure. In Zürich there was Erwin Schrödinger, in Göttingen David Hilbert, and in Cambridge Paul Adrien Maurice Dirac.

Approximation Methods,In quantum mechanics the number of problems for which there exist analytical solutions is rather restricted. In general one must resort to approximation methods. In this chapter, we present two of these methods: perturbation theory and the variational method. We are mainly interested in applications.

Spin 1/2,Spin 1/2 is the first truly revolutionary discovery of quantum mechanics. The properties of this physical quantity in itself, the importance of its existence, and the universality of its physical effects were totally unexpected.

Addition of Angular Momenta,When atomic spectral lines are observed with sufficient resolution, they appear to have in general a complex structure, each line being in fact a group of nearby components.

The Evolution of Systems,Any experimental observation or any practical use of quantum phenomena relies on . where a system evolves from a know initial state, and one performs measurements on it at some later time.
