SIR ISAAC NEWTON
England (1643 - 1727)
English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian, his Philosophæ Naturalis Principia Mathematica, published in 1687, is considered to be the most influential book in the history of science. In this work, Newton described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics, which dominated the scientific view of the physical universe for the next three centuries and is the basis for modern engineering.
