Editor's Take:

Isaac Newton did something few people in history can claim: he gave humanity a single set of rules that explained both a falling apple and the orbit of the Moon. His laws of motion and universal gravitation turned the heavens from a mystery into a machine that could be calculated. Along the way he invented much of calculus, split white light into a rainbow with a prism and built the first practical reflecting telescope. He was also secretive, quarrelsome and deeply absorbed in alchemy and biblical prophecy, a reminder that great science can live inside a complicated mind. For more than two centuries, until Einstein, the universe essentially ran on Newton's terms.
