An examination of the atom from its makeup through its operation to its many uses. The peaceful uses of atomic energy and radioactive materials are infinite. Atoms can provide fuel for fires, power for ships, aircraft and space missiles. The great strides possible through atomic power in industry, medicine and agriculture indicate what the future of these occupations will be like. The reader is given careful guided instruction in the structure of the atom, atomic fission, the secret of the A and H bombs as well as a rounded picture of the atom in action. This is a book for the science student rather than the layman. The explanations and black and white photographs are clear but for the most part they are technical.
