Restated Carnot's principle known as the Carnot cycle and gave so the theory of heat a truer and sounder basis. His most important paper, "On the Moving Force of Heat", [155] published in 1850, first stated the second law of thermodynamics. In 1865 he introduced the concept of entropy. In 1870 he introduced the virial theorem, which applied to ...
