The Birth of Quantum Mechanics

Detailed presentation of the history and physics of Einstein’s first paper from 1905, in which he introduced his quantum theory of light, the problems that solves (photoelectric effect) and the three main experimental predictions of his theory. Followed by Einstein’s quantum theory of heat capacity of solids, in which he introduced quantum vibrations in crystals.
