Computers evolve into PCs, researchers discover one new subatomic particle after another and the space age gives our psyches and science a new context.

The Industrial Revolution is in full force, Gramme invents his dynamo and James Clerk Maxwell formulates his series of equations on electrodynamics.

The first telegraphs are constructed and Michael Faraday produces much of his brilliant and enduring research into electricity and magnetism, inventing the first primitive transformer and generator.

Hans Christian Orsted's accidental discovery that an electrical current moves a compass needle rocks the scientific world; a spate of experiments follows, immediately leading to the first electromagnet and electric motor.

Scientists take important steps toward a fuller understanding of electricity, as well as some fruitful missteps, including an elaborate but incorrect theory on animal magnetism that sets the stage for a groundbreaking invention.

Aided by tools such as static electricity machines and Leyden jars, scientists continue their experiments into the fundamentals of magnetism and electricity.

Scientists' understanding of the structure of the atom and of its component particles grows, the phone and radio become common, and the modern television is born.

The Scientific Revolution takes hold, facilitating the groundbreaking work of luminaries such as William Gilbert, who took the first truly scientific approach to the study of magnetism and electricity and wrote extensively of his findings.

Albert Einstein publishes his special theory of relativity and his theory on the quantum nature of light, which he identified as both a particle and a wave. With ever new appliances, electricity begins to transform everyday life.

With his famous kite experiment and other forays into science, Benjamin Franklin advances knowledge of electricity, inspiring his English friend Joseph Priestley to do the same.

Discusses the life of Anaxagoras of Clazomenae, his ideas about the metaphysical, the physical, the cosmos, and human intelligence, and the impact he had on later intellectuals. He is especially remembered for having been the first to...
