Isaac Newton

Sir Isaac Newton, PRS (25 December 1642 (OS) – 20 March 1727 (OS) / 4 January, 1643 (NS) – 31 March 1727 (NS) was an English physicist, mathematician, astronomer, philosopher, and alchemist. Recognised as a genius of the highest order, he is widely regarded as the most influential scientist in history. He wrote the Philosophiae Naturalis Principia Mathematica (published 5 July 16871), where he described universal gravitation and, via his laws of motion, laid the groundwork for classical mechanics. Newton also shares credit with Gottfried Wilhelm Leibniz for the development of differential calculus. While they both discovered calculus nearly contemporaneously, their work was not a collaboration.

Newton was the first to promulgate a set of natural laws that could govern both terrestrial motion and celestial motion. He is associated with the scientific revolution and the advancement of heliocentrism. Newton is also credited with providing mathematical substantiation for Kepler's laws of planetary motion. He would expand these laws by arguing that orbits (such as those of comets) were not only elliptic, but could also be hyperbolic and parabolic. He is also notable for his arguments that light was composed of particles (see wave-particle duality). He was the first to realise that the spectrum of colours observed when white light passed through a prism was inherent in the white light and not added by the prism as Roger Bacon had claimed in the 13th century.

Newton also developed a law of cooling, describing the rate of cooling of objects when exposed to air; the binomial theorem in its entirety; and the principles of conservation of momentum and angular momentum. Finally, he studied the speed of sound in air, and voiced a theory of the origin of stars.
