Many believe the "Middle Ages" lacked progress, yet during this time algebra was developed, and Islamic scholars preserved and extended Greek thought (which otherwise was lost).

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.
