If there is anything which unites the sciences and the humanities it is an historical approach to a study of the men of science. In this volume of the Scientific American series brief biographies of 18 scientists are recounted within the framework of their particular fields. Within ""Magnetism and Electricity"", Franklin, Faraday, Joseph Henry and James Clerk Maxwell are highlighted; Harvey, Darwin and Pavlov are the giants of ""The Study of Life"". The continuity of the sciences is illustrated through the extension of thought from one ""great"" to another, from galileo to Newton and Hooke, from Laplace to Hamilton, Lavosier and Priestley on the isolation of oxygen. Within the area of mathematics, others are noted, particularly Lewis Carroll. This book, valuable in itself, is ideal for sparking interest in science.
