A neo-Kantian explanation of the applicability of mathematics to physics 新康德主义对数学适用于物理学的解释

{"title":"A neo-Kantian explanation of the applicability of mathematics to physics","authors":"Jorge Manero","doi":"arxiv-2408.02952","DOIUrl":"https://doi.org/arxiv-2408.02952","url":null,"abstract":"Various 'optimistic' attempts have been made to reasonably explain the\u0000undeniable effectiveness of mathematics in its application to physics. They\u0000range over retrospective, historical accounts of mathematical applicability\u0000based on pragmatic considerations, on the one side, and prospective accounts\u0000based on indispensability considerations, on the other. In view of some\u0000objections that I will raise against these accounts, I would like to propose a\u0000third alternative based on Ernst Cassirer's neo-Kantian view which can overcome\u0000these objections and embrace both pragmatic and indispensability\u0000considerations. According to this view, mathematics and physics are seen as\u0000different modes of a basic process of cognitive synthesis that are essentially\u0000applied to each other according to a priori principles of theory development\u0000inherently incorporated into scientists' minds. As emphasised by Cassirer,\u0000these principles have a constitutive role (i.e., they explain the relevant\u0000phenomena across scientific change) and a regulative role (i.e., they\u0000incorporate the ideal of unity, permanence and generality at each stage of\u0000knowledge), both of which have been captured through a functional (i.e.,\u0000structural) understanding of concepts. As a particular case study, these\u0000principles shall be instantiated by invariance groups responsible for the\u0000effectiveness of applying Lie group theory to physics.","PeriodicalId":501042,"journal":{"name":"arXiv - PHYS - History and Philosophy of Physics","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Einstein Against Singularities: Analysis versus Geometry","authors":"John D. Norton","doi":"arxiv-2408.02790","DOIUrl":"https://doi.org/arxiv-2408.02790","url":null,"abstract":"Einstein identified singularities in spacetimes, such as at the Schwarzschild\u0000radius, where later relativists only find a coordinate system assigning\u0000multiple values to a single spacetime event. These differing judgments derive\u0000from differences in mathematical methods. Later relativists employ geometrical\u0000structures to correct anomalies in the coordinate systems used in analytic\u0000expressions. Einstein took the analytic expressions to be primary and the\u0000geometrical structures as mere heuristics that could be overruled if physical\u0000assumptions required it. Einstein's non-geometric methods had a firm base in\u0000the history of mathematical methods. They continued the non-geometric\u0000orientation of Christoffel, Ricci and LeviCivita. Einstein's insistence that\u0000singularities must be eliminated marked a departure from earlier tolerance of\u0000singularities. It was founded upon his longterm project of eliminating\u0000arbitrariness from fundamental physical theories. However, Einstein was willing\u0000to theorize with singularities only temporarily if they were the least\u0000arbitrary approach then available.","PeriodicalId":501042,"journal":{"name":"arXiv - PHYS - History and Philosophy of Physics","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Julian Hirniak, an early proponent of periodic chemical reaction 朱利安-希尔尼亚克，周期性化学反应的早期倡导者

{"title":"Julian Hirniak, an early proponent of periodic chemical reaction","authors":"Niklas Manz, Yurij Holovatch, John Tyson","doi":"arxiv-2407.19945","DOIUrl":"https://doi.org/arxiv-2407.19945","url":null,"abstract":"In this article we present and discuss the work and scientific legacy of\u0000Julian Hirniak, the Ukrainian chemist and physicist who published two articles\u0000in 1908 and 1911 about periodic chemical reactions. Over the last 110+ years,\u0000his theoretical work has often been cited favorably in connection with Alfred\u0000Lotka's theoretical model of an oscillating reaction system. Other authors have\u0000pointed out thermodynamic problems in Hirniak's reaction scheme. Based on\u0000English translations of his 1908 Ukrainian and 1911 German articles, we show\u0000that Hirniak's claim (that a cycle of inter-conversions of three chemical\u0000isomers in a closed reaction vessel can show damped periodic behavior) violates\u0000the textit{Principle of Detailed Balance} (i.e., the Second Law of\u0000Thermodynamics), and that Hirniak was aware of this Principle. We also discuss\u0000his results in relation to Lotka's first model of damped oscillations in an\u0000open system of chemical reactions involving an auto-catalytic reaction\u0000operating far from equilibrium. Taking hints from both Hirniak and Lotka, we\u0000show that the mundane case of a kinase enzyme catalyzing the phosphorylation of\u0000a sugar can satisfy Hirniak's conditions for damped oscillations to its steady\u0000state flux (i.e., the Michaelis--Menten rate law), but that the oscillations\u0000are so highly damped as to be unobservable. Finally, we examine historical and\u0000factual misunderstandings related to Julian Hirniak and his publications.","PeriodicalId":501042,"journal":{"name":"arXiv - PHYS - History and Philosophy of Physics","volume":"376 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141864180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"How are Entanglement Entropies Related to Entropy Bounds?","authors":"Emily Adlam","doi":"arxiv-2407.20458","DOIUrl":"https://doi.org/arxiv-2407.20458","url":null,"abstract":"In this paper we seek to understand what current knowledge of entanglement\u0000entropies suggests about the appropriate way to interpret the covariant entropy\u0000bound. We first begin by arguing that just as in the classical case, a\u0000universal bound on the von Neumann entropy could have either an epistemic or\u0000ontological origin. We then consider several possible ways of explaining the\u0000bound as a consequence of features of the entanglement entropy. We discuss\u0000consider area laws in condensed matter and quantum field theory, arguing that\u0000they suggest an epistemic reading of the bound. We also discuss the 'spacetime\u0000from entanglement' programme, arguing that entanglement alone may not be able\u0000to full ground spacetime topology, but it could potentially play a role in\u0000determining the spacetime metric, in which case it would potentially support a\u0000more ontological reading of the bound.","PeriodicalId":501042,"journal":{"name":"arXiv - PHYS - History and Philosophy of Physics","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141864178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
