Radio waves are all around us, continuously being produced and received through man-made devices enabling us to connect with each other and communicate information. Geoffrey Gouriet, through the course of six lectures, takes us on a journey through history from the first telephone to the "Viewphone" and with the aid of exciting demonstrations he explains how devices in our house like the TV translate broadcasted signal into moving pictures.
Gouriet begins with an introduction on electromagnetic waves and the principle behind it as well as how electricity can be used to transmit information.
We then learn how we can get rid of the wires and transmit information through the "ether" using radio waves and utilizing the layers of the Earth's atmosphere to reach distant locations; the basis of radio and TV broadcasting.
Finally, Gouriet demonstrates how TVs and radios work and how broadcasted signal is translated. In his last lecture he gives us a "vision of the future" outlining how different technologies were currently (then) in development and he even sets up a live broadcast using small dishes from within the lecture theatre!
