Sir Isaac Newton was an influential English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian. In his seminal work Philosophiæ Naturalis Principia Mathematica, published in 1687, he described universal gravitation and the three laws of motion, which dominated scientific views of the physical universe for the next three centuries. Newton showed that terrestrial and celestial motions are governed by the same natural laws, removing doubts about the heliocentric model of the solar system and advancing the scientific revolution. He made important contributions to many areas of science, including optics, mathematics, and mechanics. Newton remained highly influential among scientists and is considered one of the most influential scientists in history.
