Graham, Thomas (1805-1869), a Scottish chemist. He was a pioneer in the study of the mixtures called solutions, and originated the branch of chemistry that deals with colloidal solutions. In 1834 he formulated Graham's Law, which states that the relative speeds of the diffusion of gases are inversely proportional to the square roots of their densities. Graham attended the universities of Glasgow and Edinburgh. He was a professor at the University of London, 1837-55, and was appointed master of the mint in 1855.
The man who had some theories about relativity was also an eccentric who gleefully eschewed socks, dodged German military service and spurned social conventions.
The man immortalized on the left was behind the three laws of motion and the universal law of gravitation. He was also competitive, temperamental and fascinated with alchemy. How well do you know Newton?
