|Title:||WILL SOMEONE SAY EXACTLY WHAT THE H-THEOREM PROVES - A STUDY OF BURBURY CONDITION-A AND MAXWELL PROPOSITION-II|
|Abstract:||Many historians of science, recognize that the outcome of the celebrated debate on BOLTZMANN's H-Theorem, which took place in the weekly scientific journal Nature, beginning at the end of 1894 and continuing throughout most of 1895, was the recognition of the statistical hypothesis in the proof of the theorem. This hypothesis is the Stosszahlansatz or ''hypothesis about the number of collisions.'' During the debate, the Stosszahlansatz was identified with another statistical hypothesis, which appeared in Proposition II of MAXWELL'S 1860 paper; BURBURY called it Condition A. Later in the debate, BRYAN gave a clear formulation of the Stosszahlansatz. However, the two hypotheses are prima facie different. BURBURY interchanged them without justification or even warning his readers. This point deserves clarification, since it touches upon subtle questions related to the foundation of the theory of heat. A careful reading of the arguments presented by BURBURY and BRYAN in their various invocations of both hypotheses can clarify this technical point. The Stosszahlansatz can be understood in terms of geometrical invariances of the problem of a collision between two spheres. A byproduct of my analysis is a clarification of the debate itself, which is apparently obscure.|
