The focus of twentieth-century physics has been on the infinitesimally small - and the infinitely powerful. The theory of atomism, the study of atomic structure, the subatomic physics of radio activity and fission, the still unsolved problems that constitute the frontier of physics today, all have opened up a new universe to man. In The Electron, Proton, and Neutron, Isaac Asimov gives a brilliant picture of the men and ideas that have given our world the laser beam and the H-bomb, with their mixed legacy of promise and fear.
