Electricitym simple to describe an individual atom. Atoms are of course far too small to be seen under the most powerful microscope, and we have to infer their construction from the way they behave and from the way they affect various forms of radiation beamed at them. Because nobody quite knows just what an a

The application to a machine like a record-player, for example, is an obvious one, for the small electric signal produced by the player’s pick-up cartridge must be amplified to a sufficiently large extent to drive a speaker. A system diagram of a record-player amplifier looks quite simple (see

Radio and Television impact on society. Oddly, we can use radio, predict its properties and design circuits that work very efficiently, but we know little about the real nature of radio. Ask an electronics engineer what radio is, and the answer will be a confident, ‘Electromagnetic waves.’ Ask a physicist what electrom
