Do you know what a Joule is?
James Prescott Joule was born in Manchester, England, in 1818. Like Ampere, he was home schooled and was sent to university at Cambridge when he was sixteen.
The Industrial Revolution was in full swing at this time, and one of Joule's ambitions was to replace steam-driven engines with electric motors, so his first investigations were into the production of heat.
Since Joule's research was self-funded, he was free to pursue the areas he wished and this resulted in him establishing the equivalence between heat and mechanical work as well as the cooling effect of rapidly expanded gas (the latter of which is used in refrigeration systems). Joule can also be considered as an inventor; among his inventions were arc welding and the displacement pump.
