  In 1872 Boltzmann published one of his most important papers, its long title often abbreviated as Weitere Studien (Further studies). It was aimed at something completely new, namely at showing that whatever the initial state of a gas system was, it would always tend to evolve to equilibrium.  Thus, this paper is the first work to deal with non-equilibrium theory.  The paper contained two celebrated results nowadays known as the Boltzmann equation and the H-theorem. The latter result was the basis of Boltzmann's renewed claim to have obtained a general theorem corresponding to the second law. This paper has been studied and commented upon by numerous authors. Indeed an integral translation of the text has been provided by (Brush 1966).  Thus, for present purposes, a succinct summary of the main points might have been sufficient. However, there is still dispute among modern commentators about its actual content.
