ABSTRACT
ONE of the difficulties in understanding the modern world is that many of the things we use cannot be explained in simple language. The inventions of the engineers in the first Industrial Revolution like the steam engine or power loom are not difficult to describe or understand, but most of the discoveries of the scientists which have done so much to bring about the Industrial Revolution of our time cannot be described in terms that most of us can understand. This is especially true when we turn to electronics the basis of some of our most rapidly growing industries. But if we cannot explain the science of electronics we can at least see what great changes have been brought about by the use of electronics in everyday life.
