Imaginative treatment of the advancing front of science, on the threshold of the greatest technological advance since the discovery of the internal combustion engine, speeded up by wartime research. Communications, transportation, power, structural materials and fabrics, reduction of manpower labor, extension of sight and hearing, control of heat and light and climatic conditions -- Manchester takes us behind the scenes and gives us glimpses of mysteries of laboratory developments and practical application. Good historical background -- vivid bits of biography -- exciting reading for even the unscientific layman. Should have wide appeal for young people.
