    In the 19th century, scientists working with chemistry and magnetism began discovering a rich variety of electrical phenomena. These were to be applied later in inventions including motors, alternating current, radio, batteries, the telephone, and much more. This is the story of a new branch of science that changed the way the world does physical work and the way it controls information, spurring the Industrial Revolution, followed by the Information Age.
