The way a radio program can travel halfway around the world and into your very living room may seem like magic. But when a picture on your television screen shows events as they are taking place 500 miles away it's more than magic.
Twirl a knob 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 a deep mystery if you don't know how radio and television work. If you do know, they are very simple.
In fact, how radio and television work is so simple that you yourself can have fum doing some of the tricks that it took scientists years and years to discover. In All About Radio and Television Jack Gould explains how a television wave is made, how to send and receive waves, how a picture is changed into electricity, how to build a foxhole radio, why we have networks, 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.
