This book does for some of the revolutionary theories of science what was done for philosophy in The Story of Philosophy. A difficult task brilliantly accomplished. Trattner, in treating a specific theory as evolved by one man, gives both a birdseye view of the steps preceding it, the cataclysmic results of the discovery, and a human, anecdotal portrait of the individual who formulated the idea. The range is broad, earth structure, light, population, evolution, disease, psychology, relativity, economic interpretation of history, etc. Essential for schools and libraries and for the serious layman, but not likely to catch the popular imagination as it presupposes a wide factual background.
