Isaac Newton FRS (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 a key figure in the scientific revolution.
His book Philosophiae Natural Mathematical Principles ("Mathematical Principles of Natural Philosophy"), first distributed in 1687, established the frameworks for old style mechanics. Newton made original commitments to optics, and he imparts credit to Gottfried Wilhelm Leibniz for the advancement of math.
Isaac Newton invented calculus, the mathematics of change, without which we could not understand the behavior of objects as tiny as electrons or as large as galaxies. His most famous work, Principal, is one of the most important scientific books ever written.
Newton discovered the law of universal gravitation, proving that the moon orbits the earth for precisely the same reason that an apple falls from a tree. He formulated three laws of motion – Newton’s Laws – which lie at the heart of the science of movement.
Furthermore , he proved that sunlight is made up of all the colors of the rainbow and he built the world's first working reflecting telescope.
