The Second Law and the Concept of Entropy
... No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work. Thus it is impossible to extract energy by heat from a high-temperature energy source and then convert all of the energy into work. At least some of the energy must be pa ...

... The argument goes like this: the universe must go from an ordered state to a disordered state according to the second law of thermodynamics. Yet for life to have evolved as Darwin said it has would require that life have gone from a low state of order to a higher state of order. This is clearly proh ...

H-theorem
In classical statistical mechanics, the H-theorem, introduced by Ludwig Boltzmann in 1872, describes the tendency to increase in the quantity H (defined below) in a nearly-ideal gas of molecules. As this quantity H was meant to represent the entropy of thermodynamics, the H-theorem was an early demonstration of the power of statistical mechanics as it claimed to derive the second law of thermodynamics—a statement about fundamentally irreversible processes—from reversible microscopic mechanics.The H-theorem is a natural consequence of the kinetic equation derived by Boltzmann that has come to be known as Boltzmann's equation. The H-theorem has led to considerable discussion about its actual implications, with major themes being: What is entropy? In what sense does Boltzmann's quantity H correspond to the thermodynamic entropy? Are the assumptions (such as the Stosszahlansatz described below) behind Boltzmann's equation too strong? When are these assumptions violated?↑
