A brilliantly successful and heroic effort to present to the educated layman all the major developments and trends in modern science in understandable terms. Probably only Isaac Asimov could have done this. His instinct for lucid explanation makes him one of America's greatest scientist-expositors, for all ages. With an uncanny sense of proportion (he knows what to leave out as well as what to include), he has written a magnificent survey of the history of science, which weaves into a whole the significant contributions of some 500 master investigators in every field. His dependably felcitous style is carefully controlled because of the scope, which would have terrified a lesser man. But the real secret of his success- his superb sense of organization- is more evident here than in his other books. In only 16 chapters he presents his story of the questions man has asked about the Universe, the World, Life. He reveals scientists' investigations of the secrets of Life in seven chapters:- The Molecule, The Proteins, The Cell, Micro-organisms, The Human Body, The Species and The Human Mind. Carefully integrated sub-headings relate the supporting evidence relevant to his explanations. His discussions of Aspects of the Universe and the Inorganic World follow the same highly integrated pattern. Throughout, the text offers a fabulous array of historical facts, the latest ideas, the newest discoveries in every area of science. Its more than 1000 pages and hundreds of photographs and original drawings can provide any reader, with a minimal interest in science, real illumination, leads for further investigation and inspiration. There is an introduction by George W. Beadle. This belongs in every school, college and public library and will make a good gift item for the science-minded person. Special appendix on Mathematics in Science.
