Quentin Rodriguez discusses the nature of standard explanations of the universality of critical phenomena: how do they differ from other physical explanations using mathematical models (ideal gas model, harmonic oscillator model)? In what way can they be described as emergent explanations, as opposed to other types of explanations?

65Des usages pluriels d’un modèle en physique : le cas du modèle d’IsingCahiers Philosophiques 176 (1): 27-44. 2024.Le modèle d’Ising décrit les interactions locales entre des flèches fixées aux nœuds d’un réseau et orientées vers le haut ou vers le bas. Ce modèle mathématique, très abstrait, mais aussi très simple, est l’un des plus étudiés en physique moderne. Cet article s’intéresse à la nature de ce modèle et à ses fonctions épistémiques. Nous montrons qu’il a d’abord rempli une fonction représentationnelle en tant que « modèle approché » du magnétisme. Ensuite, comme « modèle-jouet » il a permis la compr…Read more

572Neutrino Physics in Historical ContextIn Michel Cribier, Jacques Dumarchez & Daniel Vignaud (eds.), History of the Neutrino 1930–2018. pp. 503-508. 2019.This contribution aims to give an overview of the historical context of neutrino physics. I will present the strong social trends that shaped physics and the way physicists worked, along the 20th century. First, we will see the background of the birth of nuclear physics in the interwar period. Then, we will examine the deep implications the Second World War had, to conclude with the specificities of post-war years for nuclear and particle physics.

143Idealizations and Analogies: Explaining Critical PhenomenaStudies in History and Philosophy of Science Part A 89 (C): 235-247. 2021.The “universality” of critical phenomena is much discussed in philosophy of scientific explanation, idealizations and philosophy of physics. Lange and Reutlinger recently opposed Batterman concerning the role of some deliberate distortions in unifying a large class of phenomena, regardless of microscopic constitution. They argue for an essential explanatory role for “commonalities” rather than that of idealizations. Building on Batterman's insight, this article aims to show that assessing the di…Read more
