Abstract

Some introductory and historical remarks arguing the necessity of quantum mechanics are followed by a description of material waves describing free particles. Heisenberg’s uncertainty relation is demonstrated and Schrödinger’s equation is made plausible. Examples of the solution of Schrödinger’s equation are shown: a particle in a well, the hydrogen atom and the harmonic oscillator. Links to classical mechanics are shown. Dirac’s ideas are introduced and an operator algebra on ket vectors is put forward. A long section on quantum measurement is presented in order to understand better how different quantum mechanics is from classical mechanics. This culminates in a discussion of the violation of the Bell inequalities.
