[^2]: Isaac Newton, Sir: Woolsthorpe, Lincolnshire 1642–1727 Kensington, London. Born as a dwarf-like child. Grew up on a farm and went to village and small town schools until 1661. After he was accepted at the University he was of medium talent until his “flaming” as a genius physicist, astronomer, mathematician 1663–1664. Professor in Cambridge 1669–1701, member of the Royal Society London 1662 and from 1703 until his death, its President. Main work: Law of Gravitation, Mathematically Adapted to the Law of Motion from Kepler, developed 1666, published 1687 in Philosophiae Naturalis Principa Mathematica. The idea of an infinitesimal mathematics came from Newton in 1663; three years later he had developed his differential mathematics. His Optics, 1704, put forth the division of light in color as well as emission theory.
