He was educated at Trinity College, Cambridge, and in 1669 accepted the mathematical professorship in that institution. While there he made his three great discoveries, of fluxions, the nature of light and colors, and the laws of gravitation. He was the author of many works, chief among which is the “Principia,” containing his theory of the universe, which brought him fame and riches. His generosity was remarkable; he frequently entertained in a royal manner his many friends, and his kindness and courtesy toward foreigners was very marked.
