He published his first scientific paper at the age of 16, in defense of Joseph Fourier, and five years later won the Smith's Prize after graduating from Cambridge. Much later, near the end of his life, he delivered a speech in which he described two "dark clouds" over physics, the Michelson-Morely experiment and black-body radiation, both of which Einstein soon went on to solve. He worked extensively on the tran transatlantic telegraph cable, serving as a chief scientific advisor and enjoying significant accolades upon the project's completion. His most important scientific contribution, however, was to the field of thermodynamics, where he helped develop the modern theory of heat and articulated forms of the first and second laws of thermodynamics. FTP, name this British physicist who created the absolute scale of temperature.
