What he did?
Isaac explained how the objects on earth and in the sky behaved. His theories proved that the same laws of physics govern both. He also developed much of the scientific method.
History about him
Sir Isaac Newton 25 December 1642 – 20 March 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 Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Leibniz for the development of calculus.
