Human thermo-dynamics

In thermodynamics, human thermo-dynamics was a term used in 1893 by English engineer Bryan Donkin, in his "The Scientific Work of Gustav Adolph Hirn", in reference to the philosophical thermodynamics and mechanical equivalent of heat of humans work of French physicist Gustav Hirn. [1]

The phrase was a precursor to C.G. Darwin's later 1952 definition of "human thermodynamics" as the science of the study of thermodynamics of human molecules in systems.

The term thermo-dynamics, to note, was coined in 1849 and stayed in use well into the 1920s, when thereafter the subject lost the hyphen.
