Physicist
James Prescott Joule
A brewer who established that heat and mechanical work are the same thing, reportedly by measuring water temperature at the top and bottom of a waterfall on his honeymoon.
James Prescott Joule was an English physicist. Joule studied the nature of heat and discovered its relationship to mechanical work. This led to the law of conservation of energy, which in turn led to the development of the first law of thermodynamics. The SI unit of energy, the joule (J), is named after him.
