Based on this analysis, using the renormalization group and finitesize scaling, we give a definition of a large but finite system and argue that phase transitions are represented correctly, as incipient singularities in such systems. We describe the role of the thermodynamic limit. And we explore the implications of this pictu…Read more

22The question of negative temperatures in thermodynamics and statistical mechanicsStudies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 67 2663. 2019.We show that both positive and negative absolute temperatures and monotonically increasing and decreasing entropy in adiabatic processes are consistent with Carathéodory's version of the second law and we explore the modifications of the Kelvin–Planck and Clausius versions which are needed to accommodate these possibilities. We show, in part by using the equivalence of distributions and the canonical distribution, that the correct microcanonical entropy, is the surface (Boltzmann) form rather th…Read more

31The problem of equilibrium processes in thermodynamicsStudies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 62 136144. 2018.It is wellknown that the invocation of `equilibrium processes' in thermodynamics is oxymoronic. However, their prevalence and utility, particularly in elementary accounts, presents a problem. We consider a way in which their role can be played by sets of sequences of processes demarcated by curves carrying the property of accessibility. We also examine the vexed question of whether equilibrium processes are necessarily reversible and the revision of this property in relation to sets of sequence…Read more

158Boltzmann, Gibbs, and the concept of equilibriumPhilosophy of Science 75 (5): 682696. 2008.The Boltzmann and Gibbs approaches to statistical mechanics have very different definitions of equilibrium and entropy. The problems associated with this are discussed and it is suggested that they can be resolved, to produce a version of statistical mechanics incorporating both approaches, by redefining equilibrium not as a binary property but as a continuous property measured by the Boltzmann entropy and by introducing the idea of thermodynamiclike behaviour for the Boltzmann entropy. The Kac…Read more

131Review: The Work of E. T. Jaynes on Probability, Statistics and Statistical Physics (review)British Journal for the Philosophy of Science 36 (2). 1985.An important contribution to the foundations of probability theory, statistics and statistical physics has been made by E. T. Jaynes. The recent publication of his collected works provides an appropriate opportunity to attempt an assessment of this contribution.

81The SpinEcho System ReconsideredFoundations of Physics 34 (4): 669688. 2004.Simple models have played an important role in the discussion of foundational issues in statistical mechanics. Among them the spinecho system is of particular interest since it can be realized experimentally. This has led to inferences being drawn about approaches to the foundations of statistical mechanics, particularly with respect to the use of coarsegraining. We examine these claims with the help of computer simulations.
