A Is for Atom: General Electric sponsors this explanation of atomic energy, detailing some of its uses besides the bomb. Using animation and an off-screen narrator, the film describes the atom, elements and isotopes, the discovery of transmutation, experiments in artificial transmutation, and the reasons for the power of nuclear fission. The film argues that now, besides war, the atomic age holds promise for energy, farming, medicine, and research. The promise of the atomic age will depend on human wisdom.
