During 1665-66 he discovered the binomial theorem, and differential and integral calculus, and also began to investigate the phenomenon of gravitation. In 1685, he expounded his universal law of gravitation. His Philosophiae naturalis principia mathematica, usually referred to as Principia, was published in 1687, with the aid of Edmund Halley.
