Physics 1942 – 1962 presents Nobel Lectures on physics from 1942 to 1962. This book is 20 chapters that cover various Nobel physics subjects. The opening chapters deal with the topics of molecular ray methods, exclusion principle, quantum mechanics, the ionosphere, development of the Meson theory, interaction between high-speed nucleons and atomic nuclei, and the artificial production of fast particles. Other chapters discuss the principle of nuclear induction, research in nuclear magnetism, the discovery of phase contrast, statistical interpretation of quantum mechanics, the hydrogen atom structure, and the magnetic moment of the electron. The final chapters explore the semiconductor and transistor technology, laws of parity conservation, particle radiation, optics of light sources, the early antiprotron studies, elementary particles, bubble chamber, nucleus structure evaluation using the electron-scattering method, and the gamma radiation. This book is directed toward physicists.
