Sir Isaac Newton (1642-1727)

Sir Isaac Newton is universally regarded as one of the giants of physics and mathematics. He is well known for discovering the laws of motion and gravity and for inventing calculus, but he also proved the Binomial Theorem and the laws of optics, and developed methods for solving polynomial equations to any desired accuracy. He was born on Christmas Day, a few months after the death of his father. After an unhappy childhood, he entered Cambridge University, where he learned mathematics by studying the writings of Euclid and Descartes. During the plague years of 1665 and 1666, when the university was closed, Newton thought and wrote about ideas that, once published, instantly revolutionized the sciences. Imbued with a pathological fear of criticism, he published these writings only after many years of encouragement from Edmund Halley (who discovered the now-famous comet) and other colleagues. Newton's works brought him enormous fame and prestige. Even poets were moved to praise; Alexander Pope wrote:

"Nature and Nature's laws
Lay hid in Night.
God said, 'Let Newton be'
And all was Light."

Newton was far more modest about his accomplishments. He said, "I seem to have been only like a boy playing on the seashoreŠwhile the great ocean of truth lay all undiscovered before me." Newton was knighted by Queen Anne in 1705 and was buried with great honor in Westminster Abbey.
