A heurística de Boltzmann e a emergência do programa mecânico-estatístico

Abstract: O objetivo deste trabalhoé investigar a construção de uma abordagem estatística como recurso heurístico de compreensão das relações entre mecânica e termodinâmica no interior do programa de pesquisa de Ludwig Boltzmann (1844-1906. Neste contexto, a função de distribuição das velocidades moleculares de J.C. Maxwell (1831-79), acerca da qual Boltzmann fará diferentes leituras, desempenhará um papel central na medida em qué e a partir dela que novos instrumentos heurísticos surgirão, tais como os conceitos de "e… Show more

“…(2) PII Space: the space where the states are divided according to different probabilistic weights, given by the Maxwell-Boltzmann distribution and represented by what Boltzmann called Holode (Gibbs' canonical ensemble. ) We therefore identified a transition in representational heuristics in Boltzmann's program, which goes from a kinetic approach to a statistical approach, using Maxwell's speed distribution function as an element of mediation (C. Laranjeiras et al 2006). In a statistical language, we can say that in the kinetic approach, Boltzmann attributed the average property of the population (gas) to the sample.…”

“…An extensive discussion on the research program of P. Duhem can be found in(Chiappin 1989) and(Oswaldo 1998, 79-140). 7 This theme was the subject of a previous publication(Laranjeiras et al 2006) made by us when we emphasized Boltzmann`s research program based on the tools and methods used by him in the analysis of thermal phenomena. 8 From a modern perspective, we could say that statistical mechanics is a formalism that seeks to objectively explain the physical properties of a very large quantity of matter based on the dynamic behaviour of its microscopic constituents(Pathria 1972).…”

“…In Maxwell, we find not only the combination of his gas model ("hard sphere model") with the existence of a "function distribution of molecular speeds", but also his subsequent use of the Lagrangian and Hamiltonian formulation of analytical mechanics in the theoretical organization of electromagnetism to reconcile his mechanical interpretation. [18], [19], [20, p. 297]. both by the idea of minimizing the path of light as by minimizing the travel time.…”

“…It is exactly what physicists have been doing, and examples in physics are abundant. This is the case in the work of Helmholtz, Boltzmann, Clausius, and Maxwell (Laranjeiras 2002;Laranjeiras and Chiappin 2006). Helmholtz employed the mechanistic program according to the analytic method, where the hypothesis of a system of hidden masses in motion assumes the form of monocyclic systems, generated by Lagrange's equations, to build up mechanical illustrations, for instance of the second law of thermodynamics (Laranjeiras and Chiappin 2008).…”
