Class : 6 Isaac Newton

Isaac Newton was born (according to the Julian calendar in use in England at the time) on Christmas Day, 25 December 1642, at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire.

Although it was claimed that he was once engaged, Newton never married. He was an English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian who has been considered by many to be the greatest and most influential scientist who ever lived. Newton described universal gravitation and the three laws of motion. He built the first practical reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into the many colours that form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound. In mathematics, Newton shares the credit with Gottfried Leibniz for the development of differential and integral calculus. He generalized the binomial theorem to non-integer exponents, developed Newton’s method for approximating the roots of a function, and contributed to the study of power series. Towards the end of his life, Newton took up residence at Cranbury Park, near Winchester with his niece and her...
