Second law of thermodynamics
The second law of thermodynamics may be expressed in many specific ways, the most prominent classical statements being the statement by Rudolf Clausius (1854), the statement by Lord Kelvin (1851), and the statement in axiomatic thermodynamics by Constantin Carathéodory (1909). These statements cast the law in general physical terms citing the impossibility of certain processes. The Clausius and the Kelvin statements have been shown to be equivalent.
Stephen G. Brush
His work on the history of thermodynamics began with a series of essays in "Annals of Science" (1957/1958) on the kinetic theory of gases. In this work he brought attention to forgotten precursors of kinetic theory like John Herapath and John James Waterston, who formulated the law of equal distribution in 1845 rejected by the Royal Society. In 1964 Brush translated the lectures of Ludwig Boltzmann on Gas Theory into English, and edited several reprint volumes of classical works from statistical mechanics. His first set of two books on Kinetic Theory of Gases was published by Pergamon Press in 1966. The third volume of the series was published in 1972. This was followed by a two volume set called The Kind of Motion We Call Heat, published in 1976, and The Temperature of History, in 1978 (see Publications list).
