However, his most important discoveries were made during the two-year period from 1664 to 1666, when the university was closed due to the Great Plague. Newton retreated to his hometown and set to work on developing calculus, as well as advanced studies on optics and gravitation. It was at this time that he discovered the Law of Uni- versal Gravitation and discovered that white light is composed of all the colors of the spectrum. These findings enabled him to make fun- damental contributions to mathematics, astronomy, and theoretical and experimental physics. Arguably, it is for Newton’s Laws of Motion that he is most revered. These are the three basic laws that govern the motion of material objects. Together, they gave rise to a general view of nature known as the clockwork universe. The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction. In 1687, Newton summarized his discoveries in terrestrial and celestial mechanics in his Philosophiae naturalis principia mathematica (Mathematical Principles of Natural Philosophy), one of the greatest milestones in the history of science. In this work he showed how his principle of universal gravitation provided an explanation both of falling bodies on the earth and of the motions of planets, comets, and other bodies in the heavens. The first part of the Principia, devoted to dynamics, includes Newton’s three laws of motion; the second part to fluid motion and other topics; and the third part to the system of the world, in which, among other things, he provides an explanation of Kepler’s laws of planetary motion. This is not all of Newton’s groundbreaking work. In 1704, his dis- coveries in optics were presented in Opticks, in which he elaborated his theory that light is composed of corpuscles, or particles. Among his other accomplishments were his construction (1668) of a reflecting telescope and his anticipation of the calculus of variations, founded by Gottfried Leibniz and the Bernoullis. In later years, Newton consid- ered mathematics and physics a recreation and turned much of his energy toward alchemy, theology, and history, particularly problems of chronology. Newton achieved many honors over his years of service to the advancement of science and mathematics, as well as for his role as war- den, then master, of the mint.
