Profile

I specialize in researching the historical development of physics, particularly in the Western world from the late 19th century to the early 20th century. My main research topics are as follows:

(1) The history of statistical mechanics from the late 19th century to the early 20th century

Traditionally, the history of statistical mechanics has been centered on the kinetic theory of gases by the Austrian physicist Ludwig Boltzmann (1844–1906). However, I have reconstructed the making of statistical mechanics during this period from the perspective of statistical mechanics as a computational tool, focusing on the formation and inheritance process of the ensemble theory by the American physicist Josiah Willard Gibbs (1839–1903). My book, The Making of Statistical Mechanics (Nagoya University Press, 2021; in Japanese), summarizes this achievement.

(2) The mechanical worldviews in the late 19th century
Statistical mechanics has been considered a representative tool to achieve the so-called mechanical view of nature. In the KAKENHI research project adopted from the fiscal year 2023, I aim to clarify the diversity of the mechanical worldviews by examining the ontological, epistemological, and disciplinary perspectives of the fundamental theory of statistical mechanics, i.e., classical mechanics. I will investigate how this theory was originally conceived and understood and its relationship with the mechanical worldviews.

(3) The energetic theories in the late 19th century
In the late 19th century, various positions were advocated as the counterpart of the mechanical view of nature. The energetics of Wilhelm Ostwald (1853–1932) is one of them. By examining the arguments of the energetics from the same perspective as (2) and contrasting them with the mechanical worldviews, I aim to clarify not only the characteristics of the energetics itself but also the mechanical worldviews and, ultimately, the physical worldviews of the late 19th century.

  • The genealogy of ensemble theories and thermodynamic analogies: A study on J. Willard Gibbs' Elementary principles in statistical mechanics Reviewed

    This paper shows that Josiah Willard Gibbs (1839–1903) integrated Helmholtzian thermodynamic analogies with the Boltzmann-Maxwellian ensemble approach in his book Elementary principles in statistical mechanics (1902). On one hand, Gibbs took over the ensemble concept from Maxwell and Boltzmann, who developed it in the 1870s and 1880s. A lecture note taken by a Gibbs' student reveals that Gibbs finished his theory of statistical mechanics following the Boltzmann-Maxwell line almost completely by 1895. On the other hand, Gibbs made analogies with thermodynamics in Helmholtz's sense; in 1884 Helmholtz suggested the idea of monocyclic systems to establish the fact that there are formal and operational correspondences between mechanics and thermodynamics. In the same year, Boltzmann extended the domain of monocyclic systems by means of ensembles, but he made only formal analogies. The lecture note also mentions formal analogies. In the Elementary principles, Gibbs applied the ensemble concept to make both formal and operational analogies, as can be seen in Helmholtz. Although there is no direct evidence that Gibbs studied Helmholtz's monocyclic systems, a detailed analysis allows us to interpret Gibbs' theory as succeeding Helmholtz' thermodynamic analogies.

    This paper reveals that Josiah Willard Gibbs (1839-1903) attempted to explain certain chemical properties of matter, such as osmotic pressure of "diaphragms" (semi-permeable membranes) and electromotive force of chemical cells, from his theory of statistical mechanics, i.e., Elementary Principles in Statistical Mechanics (1902; EPSM). To begin with, I examine his thermodynamical theory developed in "On the Equilibrium of Heterogeneous Substances" (1876/78; EHS). Later, I attempt to support the above claim by analyzing his theory of statistical mechanics. In EHS and his later discussions on ...
