Sir Isaac Newton

The seventeenth-century mathematician who laid the foundations of modern physics.

Sir Isaac Newton (1642–1727) was a Lincolnshire-born mathematician and physicist whose work transformed European science. His three laws of motion and his theory of universal gravitation, set out in the Principia Mathematica of 1687, explained the orbits of the planets and the motion of objects on Earth using a single mathematical framework. He also made fundamental contributions to optics and to the development of calculus.
