Definition of Joule, James Prescott
- (1818–89), British physicist. He established that all forms of energy were basically the same and interchangeable—the first law of thermodynamics. The Joule-Thomson effect, discovered with William Thomson (later Lord Kelvin) in 1852, led to the development of the refrigerator and to the science of cryogenics.
