This scientist discovered heat's relationship to mechanical work. And he sure was workin' it with that beard. Name this man of science.

Joule was instrumental in teaching the world about how work creates energy and heat, and his work directly led to the law of conservation of energy, which in turn led to the development of the first law of thermodynamics. He even has a unit of heat named after him!
