When your television screen lights up with a colored picture, it seems like magic. But when a radar signal comes back from the moon, it's more than magic. This is evidence of one of the most fascinating and important developments in the world of science.
Twirl a knob on your TV set, and you make the picture brighter or darker. Turn another and you make the voice louder or softer. What you can't see are the strange and fascinating things that happen inside a set when you turn those knobs. These things are baffling if you don't know how radio and television work. But if you do know, they become very clear.
In fact, the working principles of radio and television are so simple that you can perform some of the experiments it took scientists years to discover. In the 1958 edition of All About Radio and Television, Jack Gould explains how a television wave is made, how a picture is changed into electricity, why we have networks, how the transistor works, and even how to communicate with the moon by radar.
Over 100 illustrations help explain the hows and whys of radio and television in this fascinating book.
