A book by a prolific writer on science and scientific developments (see his It orks Like This, Plastics in the World of Tomorrow) reveals the world beyond the factory door- with specific regard to cellulose, nylon, glass, electronics, the atomic battery, the gas turbine and the silicones. Pithy information on each of these topics has been outlined to tell the origin, development, and uses for the various products. The material on glass for example, relates the old Egyptian formulas still in use today, their variations (lead glass is used for many camera lenses), and the making of the huge Palomar telescope. Clear descriptions too, tell Just exactly how many other familiar products are made. Speculations on the future and a certain flair for the drama of science gear this for scientific bents.
