Electricity Physics

Two of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by 40 years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time.

For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders—complete with roller coasters and radar, computer networks and psychopharmaceuticals.

Regenerative medicine has long targeted the impossible - regrowing a diseased organ, or a hand lost in an accident. But biologist Michael Levin thinks an astonishing breakthrough may be within reach. He has resurrected a much-maligned branch of science, and shown that a little-understood process can trigger remarkable feats of regeneration in animals. As his research advances, he's moving us closer to the day when regeneration is possible in people.
