science · 05 July 1687 · 337 years ago

Isaac Newton's Philosophiæ Naturalis Principia Mathematica, known as the Principia, is published by the Royal Society of London. In it, Newton describes his theory of universal gravitation, explains the laws of mechanics (including Newton's laws of motion), gives a formula for the speed of sound and demonstrates that Earth is an oblate spheroid. The concepts in the Principia become the foundations of modern physics.
