From the wireless to the think machines and the possible leisure time creative society automation may provide for the future, this is an interestingly written survey of the electronic field. First Mr. Stoddard tells us what electricity is in its many forms and then describes the chain of inventions that brought electronics to their present advanced state. The work of Marconi provided the background for a definition of radio waves and of the other work radio does such as cabling and sending photographs. Receiving the human voice was made possible by De Forest's development of the detecting tube which has in turn resulted in the vast network of stations, programs, sets and props today. Radar and its uses (from detecting airplanes to grading oranges), television broadcasting, x-rays, electronic microscopes, and the machines that learn and think, make up the rest of a remarkable roster.
