A is for Atom (1952)
Animated classic presenting what an atom is, how energy is released from certain kinds of atoms, the peacetime uses of atomic energy and the byproducts of nuclear fission. The Atomic Age, also known as the Atomic Era, is a phrase typically used to delineate the period of history following the detonation of the first nuclear bomb on Hiroshima, Japan in 1945. Although nuclear science existed before this event, the bombing of Hiroshima represented the first large-scale, practical use of nuclear technology and ushered in profound changes in socio-political thinking and the course of technology development.
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.
