This third, revised edition brings up to date the story of physics' contribution to modern living. Clear and vivid without being sensational, this book ranks among the best in popular science writing. Dealing with developments in optics, electronics, meteorology, communication, medicine, atomic energy and many other subjects, the author has packed an astonishing amount of information into a lucid, easily flowing book. A well-chosen bibliography and practical index add to its usefulness as reference and supplementary reading material. If only it had illustrations, it would have been tops in science.
