Richardson's law

In 1901, Owen Willans Richardson read a paper before the Cambridge Philosophical Society which first announced his work on thermionic emission (the release of electrons from hot metals) and in particular a law which mathematically described how the amount of electron current increased as the temperature of the hot surface was raised. (He had been working at the Cavendish Laboratory only one year since his graduation from Cambridge University.) As recorded in the published Proceedings, in Richardson's words: "If then the negative radiation is due to the corpuscles coming out of the metal, the saturation current s should obey the law s = AT1/2e-b/T." The discovery of Richardson's law earned him the 1928 Nobel Prize for Physics.
