Isaac Newton

Sir Isaac Newton PRS (25 December 1642 - 20 March 1727) was an English mathematician, physicist, astronomer, and natural philosopher whose work laid the foundations of modern science. He is best known for formulating the laws of motion and universal gravitation, which unified the physics of the heavens and the earth under a single framework. Newton also made fundamental contributions to optics, demonstrating that white light is composed of a spectrum of colors, and independently developed calculus, which became a cornerstone of mathematics.

Born in Woolsthorpe, Lincolnshire, Newton studied at Trinity College, Cambridge, where he began developing ideas that would transform natural philosophy. His Philosophiæ Naturalis Principia Mathematica (1687), often called the Principia, is one of the most influential books in the history of science, introducing a precise mathematical description of nature that endured for centuries. Beyond mechanics, Newton served as Lucasian Professor of Mathematics, President of the Royal Society, and later as Master of the Royal Mint, where he reformed England's coinage.

Newton's intellectual reach extended into alchemy, theology, and biblical chronology, reflecting his view of science as inseparable from the search for universal truth. Although often reclusive and fiercely protective of his discoveries, he became a towering figure of the Enlightenment, knighted in 1705, and celebrated as one of history's greatest scientific minds.
