This text appeals to readers' intuitive grasp of the wave theory of light, explaining how quantum mechanics arises from the diffraction and interference experiments in the same manner of physical optics. Coherent examples explore the quantum mechanical analog of classical quantities and examine the physical meanings of the theory and its applications. 1963 edition.
David B. Beard (1922-98) was the University Distinguished Professor of Physics at the University of Kansas, where he taught for more than 20 years and served as Chairman of the Department of Physics and Astronomy from 1964 to 1977.
