	~~Charles Babbage~~		Isaac Newton
	* ~~Digital representation~~		* Brilliant mathematician and physicist, discovered the Law of Gravitation of spheres, Newton's Laws of Motion
	* ~~Computer~~		* Physics: Newton's Three Laws (body in motion stays in motion until acted upon, F=ma, for every action equal opposite reaction)
			* Physics: Newton's Law of Gravitation (two planets, multi-body problem)
			* Mathematics: invented the calculus, and as if that weren't enough, created Newton's Method for finding roots of equations (still used on modern computers to calculate square roots), binomial expansions, infinite series
			* Optics: discovered light was a particle, uncovered nature of color and its connection to wavelengths of photons, white being combination of all colors
			* Lucasian Professor of Mathematics at Cambridge
			* Retired from Cambridge, worked as the Warden of the Mint
			* Mint: London was having a financial crisis because of counterfeit money, Newton applied his talents to making coins and bank notes that could not be counterfeited (hard problem! making something that's hard to make a copy of, on a really really big scale)
			* Economics: Newton was the first to devise a comprehensive system for paper money in the British economy, starting in London; this helped to make Britain a financial power, and made London the world's financial center, which it still is to this day
