Description

This series explains and illustrates the science of physics and its everday applications. Physics is concered with matter - the stuff from which everything is made - and with energy in all its forms. This book revolves around the electron, the tiny, negatively charged particle that is found in the atoms of all elements, and looks at electric current and the development of electronics, from early vacuum tubes through to today's microchips and semiconductors. Explanatory diagrams and simple practical experiments help to provide a perfect introduction to this fascinating subject.
