Einstein et «Zweistein»

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest.     

Quelques repéres historiques sur la théorie des jeux

Résumé  L'article s'attache à dégager le fil rouge qui relie les réflexions de Wilhelm Gottfried Leibniz sur les jeux de société à la théorie des jeux, telle qu'on la trouve dans l'ouvrage de John Von Neumann et Oskar Morgenstern. L'itinéraire décrit passe par les travaux de plusieurs mathématiciens du XVIII^e siècle sur différents jeux de hasard, pour aboutir aux recherches de quelques-uns des fondateurs des mathématiques modernes, comme Ernst Zermelo pour la théorie des ensembles et émile Borel pour la théorie des probabilités. II montre comment une analyse mathématique des jeux de société a débouché sur l'élaboration d'une grille générale d'analyse des phénomènes sociaux. Son cheminement révèle, en outre, la longue parenthèse du XIX^e siècle où ce programme s'est trouvé abandonné et esquisse, en conclusion, quelques hypothèses pour l'expliquer. The paper strives to find the clue which links Leibniz' thoughts on parlour games to the mathematical theory of games in John Von Neumann and Oskar Morgenstern.Magna opera the way goes through the works of several XVIII^th century mathematicians on various games of chance to reach the research of some of the modern mathematics founders, as Ernst Zermelo for the sets theory and émile Borel for the theory of probabilities. The paper shows how a mathematical analysis of parlour games ends at a general framework to study the social phenomena. Its development also reveals how this research program has disappeared, all along the XIX^th century, and suggests, in conclusion, some tentative explanations of this development.

Zwei oder drei Dinge, die ich von der Technikphilosophie weiss

Nearby a somehow “official“ philosophy of technique, works have appeared in recent German literature where different techniques are studied according a renewed philosophical agenda about their concrete historical development. Once 19th Century German philosophy of technique briefly sketched, a sample from this recent production is considered. Surprisingly, they are meeting current literary studies and cultural history.     

Researching ‘gay Cape Town’ finding value-added queerness

An initiative to market Cape Town as a premier gay and lesbian tourist destination has steadily gathered steam over the last decade. I set out to study this phenomenon thereby adding to conversations about the normalization and globalization of queerness. Rather than straightforwardly presenting my findings, however, this paper considers queer theorizing as an inductive process by detailing the answers I did not find in the field and the questions I did. Based on my close readings of queer theory, I went looking for resistance and therefore queerness in the normalized space of ‘gay Cape Town’. I was disappointed. But I did not instead find outright capitulation. Rather, in this process of queer's commodification, I found anxieties, cracks and fissures beneath a veneer of assured mainstreaming. I found an undetermined process that did not represent either ‘un-African-ness’ or ‘global queer homogeneity’ or ‘African-ness’ and ‘local queer heterogeneity’. I found not an un-queering through commodification, but a queer commodity struggling to gain a foothold in a nation in which the terrain for gay and lesbian politics has drastically changed in such a way that the market cannot be ignored. To grapple with these findings, I argue for a more ambivalent approach to queer theorizing.     

Long-term trends in health status and determinants of health among the off-reserve Indigenous population in Canada, 1991–2012

The Indigenous population in Canada totals approximately 1.6 million individuals, representing about 5% of the total population. The off-reserve Indigenous population represents the fastest growing segment of the Indigenous population, with over 50% living in urban settings. Despite the size of the off-reserve population, research on the health of Indigenous peoples tends to remain focused on reserve-based populations. The purpose of this paper is to contribute to a better understanding of health and social determinants of health among off-reserve Indigenous peoples in Canada. Using data from the 1991 and 2012 Aboriginal Peoples Surveys this paper examines changes in health status and the social determinants of health over a 20-year time span. Results show a decline in health care use and self-reported health status in the period between 1991 and 2012. The results may be related to urbanization, aging, and increased prevalence of some chronic conditions. The findings may also be tied to barriers to achieving adequate off-reserve health care—jurisdictional disputes, disjointed program coverage, systemic racism, and a lack of equity-oriented health services. There remains a pressing need for Indigenous and non-Indigenous governments, researchers, and policymakers to build new relationships that bridge these gaps in health and access to timely care.
