ISAAC NEWTON (1642~1727)
A British physicist and mathematician. He is hailed as one of the Three Great Mathematicians. His first great discovery (the spectrum of light) was finding that white light was an amalgam of monochromatic light. Next, using his Universal Law of Gravitation, he successfully mathematically proved that planets move along elliptical orbits. The significance of this was explaining the movement of celestial and terrestial bodies under one law. The manuscript of his collective theories, 'Principia', took the world by storm, and Newton went on to obtain immutable fame. In 1705 he was knighted and known henceforth as 'Sir Isaac Newton'.
