Nowadays, one can find a wide range of different definitions. Some of them seem mutually exclusive, but traditionally, its notion has been linked to the fine-tuning problem. Understanding naturalness as the imposition that fine-tuning problems have to vanish, for instance, due to the existence of new particles, new models as those based in supersymmetry were built. In order to palliate the fine-tuning problem the Higgs sector of the standard model seems to suffer, new physics should have appeared already in the last LHC run. Thus, the persistence of fine-tuning has originated numerous works exploring both, the limits and the different conceptual definitions of naturalness. However, little work has been done re-examining precisely one of the main pillars naturalness advocates: its historical successes. Given the current period in which the critics to the naturalness principle are undergoing, we find important to explore in detail the historical examples often cited, primarily the charm quark proposal and its mass prediction, and see how can this contribute to the debate.</div>","PeriodicalId":54442,"journal":{"name":"Studies in History and Philosophy of Modern Physics","volume":"68 ","pages":"Pages 51-61"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.shpsb.2019.06.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73873528","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}

The multiple-computations theorem implies that certain physical systems implement simultaneously more than one computation. Landauer's principle implies that the physical implementation of “logically irreversible” functions is accompanied by minimal entropy increase. We show that the multiple-computations theorem is incompatible with, or at least challenges, the universal validity of Landauer's principle. To this end we provide accounts of both ideas in terms of low-level fundamental concepts in statistical mechanics, thus providing a deeper understanding of these ideas than their standard formulations given in the high-level terms of thermodynamics and cognitive science. Since Landauer's principle is pivotal in the attempts to derive the universal validity of the second law of thermodynamics in statistical mechanics, our result entails that the multiple-computations theorem has crucial implications with respect to the second law. Finally, our analysis contributes to the understanding of notions, such as “logical irreversibility,” “entropy increase,” “implementing a computation,” in terms of fundamental physics, and to resolving open questions in the literature of both fields, such as: what could it possibly mean that a certain physical process implements a certain computation.</div>","PeriodicalId":54442,"journal":{"name":"Studies in History and Philosophy of Modern Physics","volume":"68 ","pages":"Pages 90-105"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.shpsb.2019.07.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81994355","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}
