English physicist, mathematician, and astronomer (1643–1727), widely regarded as the most influential figure in the history of science, whose ideas and discoveries, including calculus, the laws of gravitation and motion, and observations on the nature of light and optics, earned him a place among the most profound geniuses in the history of mankind.
