The Principia: Mathematical Principles of Natural Philosophy: Original Edition (Latin Edition)

Sir Isaac Newton PRS MP (25 December 1642 20 March 1726) was an English physicist and mathematician (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophi Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. Newton also made seminal contributions to optics and shares credit with Gottfried Leibniz for the invention of calculus. --wikipeida.org
