First edition.
Louis de Broglie (1892-1987) was a French physicist, and winner of the 1929 Nobel Prize in Physics for his discovery of the wave nature of electrons. He is one of the founding fathers of quantum mechanics. This work is a presentation of the fundamental principles of wave mechanics, a physical theory that revolutionized the understanding of matter at the subatomic level.
