View source for James Prescott Joule (nonfiction)

'''James Prescott Joule''' FRS HFRSE DCL LLD (24 December 1818 – 11 October 1889) was an English physicist and brewer, born in Salford, Lancashire. 

Joule studied the nature of heat, and discovered its relationship to mechanical work (see energy). This led to the law of conservation of energy, which led to the development of the first law of thermodynamics.

He worked with [[William Thomson, 1st Baron Kelvin (nonfiction)|Lord Kelvin]] to develop the absolute scale of temperature, which came to be called the Kelvin scale.

Joule also made observations of magnetostriction, and he found the relationship between the current through a resistor and the heat dissipated, which is now called Joule's first law.

The SI derived unit of energy, the joule, is named after him.
