After annotating and correcting his personal copy of the first edition, Newton also published two further editions, in 1713 and 1726. The Principia states Newton's laws of motion, forming the foundation of classical mechanics, also Newton's law of universal gravitation, and a derivation of Kepler's laws of planetary motion (which Kepler first obtained empirically). The Principia is justly regarded as one of the most important works in the history of science. Sat, 15 Jun 2013 15:41:19 GMT http://hdl.handle.net/123456789/346 2013-06-15T15:41:19Z
