What is commonly known as the Copenhagen interpretation of quantum mechanics, regarded as representing a unitary Copenhagen point of view, differs significantly from Bohr's complementarity interpretation, which does not employ wave packet collapse in its account of measurement and does not accord the subjective observer any privileged role in measurement. It is argued that the Copenhagen interpretation is an invention of the mid‐1950s, for which Heisenberg is chiefly responsible, various other physicists and philosophers, including Bohm, Feyerabend, Hanson, and Popper, having (...) further promoted the invention in the service of their own philosophical agendas.

This paper explores the fundamental ideas that have motivated the idea of emergence and the movement of emergentism. The concept of reduction, which lies at the heart of the emergence idea is explicated, and it is shown how the thesis that emergent properties are irreducible gives a unified account of emergence. The paper goes on to discuss two fundamental unresolved issues for emergentism. The first is that of giving a “positive” characterization of emergence; the second is to give a coherent (...) explanation of how “downward” causation, a central component of emergentism, is able to avoid the problem of overdetermination.

Hilbert's axiomatization program of physical theories met an interesting challenge when it confronted the rise of quantum mechanics in the mid-twenties. The novelty of the mathematical apparatus of the then newly born theory was to be matched only by its substantial lack of any definite physical interpretation. The early attempts at axiomatization, which are described here, reflect all the difficulty of the task faced by Jordan, Hilbert, von Neumann and others. The role of von Neumann is examined in considerable detail (...) as he can be viewed here as the most outstanding of Hilbert's heirs. Von Neumann, especially in his work devoted to the proof of the impossibility of hidden variables, not only continued Hilbert's program but pushed it to its very limits, blending axiomatic rigor and interpretative commitment.

Following Lenin’s critique of Mach in Materialism and Empiriocriticism, the name of the Austrian philosopher was often used in the Soviet Union to discredit philosophical positions, theories, or individuals, because of the assumed influence he had on them. This is what we define as the “Mach argument”, a matter of rhetoric that usually did not require any additional explanations and suited the political discourse required by the Soviet regime. This chapter aims to study its use by the Soviet physicist Vladimir (...) Fock, to better understand the modalities of his scientific discourse. It highlights the complex situation he faced, as his need to defend modern theories of physics against unjustified ideological attacks in the Soviet Union was in some way at odds with his own belief that their interpretations needed revision. In response, Fock elaborated a strategy that required a form of politicization of his professional culture. Nevertheless, we argue that the scientist showed a great capacity for adaptation as it did not mean in any way an abandonment of his traditional scientific values and principles. (shrink)

This article examines the forces that have made federal scientific publication an essentially private enterprise. Particular attention is paid to the rise of the scientific community in the American political system. The period under review begins roughly with 1941 and American involvement in World War II, which coincides with the establishment of the Office of Scientific Research and Development (ORSD). The article examines OSRD's method of conducting federal scientific research, its contractual system, and the new publishing paradigm that it engendered. (...) The article concludes in the 1960s with congressional efforts to revise provisions in Title 17, the. (shrink)

Este trabalho analisa idéias e atividades de Karl Popper referentes à controvérsia sobre interpretações e fundamentos da mecânica quântica. Atenção especial será dedicada às relações entre Popper e o físico italiano Franco Selleri, ao longo da década de 1980. A interpretação proposta por Popper para os enunciados probabilísticos como propensões, bem como seu ponto de vista realista, contribuíram para estabelecer uma ponte entre suas investigações filosóficas e a pesquisa física em mecânica quântica, ainda que sua idéia sobre as propensões tenha (...) tido uma pequena repercussão entre físicos, matemáticos e filósofos. Argumentaremos neste trabalho que a influência de Popper na física foi possível devido à legitimação, a partir de 1970, da controvérsia sobre os fundamentos da teoria quântica como uma genuína controvérsia científica com implicações filosóficas. Popper foi beneficiado por essa legitimação, mas ele também contribuiu para fazer aquela controvérsia chegar a um público mais amplo que aquele dos físicos envolvidos na própria controvérsia.I intend to present in this paper Karl Popper’s ideas and activities concerning the controversy about the interpretations and foundations of quantum mechanics. I will pay special attention to Popper’s relationship with the Italian physicist Franco Selleri, during the 1980s. Popper’s ideas of propensity and realism contributed to build a bridge between his philosophy and physical research in quantum mechanics, even if his idea of propensity has had a weak reception among physicists, mathematicians and philosophers. I will argue that Popper’s contributions to physics were possible due to the legitimization in the 1970s of the controversy about the foundations of quantum mechanics, a process which permitted a trading zone between physics and philosophy. Popper was benefited by that process, but he also contributed to give to that controversy a larger audience thanthat of the physicists involved in that controversy. (shrink)
