Gr 6 Up Gutnik begins with a chapter on the birth of electricity, which started with the ancient Greeks, the first to use the terms electricity and magnetism. The introductory chapter summarizes developments in the field over many centuries, up to the time of Sir Humphry Davy (1778-1829). Another chapter highlights Michael Faraday (1791-1867). Later sections deal with electromagnetic communication and some of the giants in that field, such as Maxwell, Morse, Bell, Edison. Final pages are devoted to electronic theories that led to television, transistors, solar generators, and other modern technological achievements. Gutnick's text is comprehensive in its coverage, readable, and understandable, despite the esoteric material with which he deals. Another plus is the excellent choice of illustrations, from clearly labeled, simple diagrams to black-and-white photographs of unusual clarity and historic value. A glossary and chronology add to the usefulness of this book. Sue Norkeliunas, Arlington Senior High School, Poughkeepsie, N.Y.
