co-invented calculus (independently of Leibniz), providing the mathematical language for continuous change
optics: demonstrated white light is a composite of spectral colors using prism experiments
Principia Mathematica (1687): unified terrestrial and celestial mechanics under a single mathematical framework
Master of the Royal Mint, reforming English coinage and currency standards
