Quantum mechanical measurements on a physical system are represented by observables - Hermitian operators on the state space of the observed system. It is an important question whether all observables may be realized, in principle, as measurements on a physical system. Dirac’s influential text ( [1], page 37) makes the following assertion on the question: The question now presents itself – Can every observable be measured? The answer theoretically is yes. In practice it may be very awkward, or perhaps even (...) beyond the ingenuity of the experimenter, to devise an apparatus which could measure some particular observable, but the theory always allows one to imagine that the measurement can be made. This Letter re-examines the question of whether it is possible, even in principle, to measure every quantum mechanical observable. Unexpectedly, ideas from com-. (shrink)

Soviet attitude towards Bohr reflects changes in the ideological approach to science. During the last period before Stalin's death danov proclaimed the campaign against Western influence in Soviet philosophy and science. Nevertheless the physicist M. A. Markov tried to introduce complementarity as a materialistic interpretation of quantum-mechanics in 1948. He was officially condemned. This was followed by a period (1948-54) during which heavy attacks were made against the Copenhagen school. In 1958, after a personal exchange of thoughts with Bohr, academician (...) Fock declared complementarity and probability to be irreversible steps towards a new insight into physical reality, at the same time correcting some of Bohr's epistemological conceptions. (shrink)

This book integrates pragmatism and transcendental philosophy in examining the most serious problem defining the human condition, death and mortality. Its analysis of human limits and finitude is intended to be relevant to the concerns of philosophers specializing in, for example, transcendental philosophy, philosophical anthropology, pragmatism, Wittgenstein, and the philosophy of religion. Mortality is studied as providing a necessary framework within which questions concerning the meaningfulness or meaninglessness of human life become possible.

Le 9e siècle marque un tournant dans l'hagiographie byzantine qui devient de plus en plus sécularisée à la fois dans sa forme et dans son contenu. Deux Vitae datant de la fin du 9e siècle, la vie d'Antoine le jeune et la vie de l'impératrice Theodora jouent un rôle pivot dans ce processus de sécularisation. Elles offrent les modèles d'une piété masculine et d'une piété féminine en témoignant de deux formes antithétiques de l'expérience religieuse : celle monastique et celle séculaire. (...) Cette tension trouve ses racines dans l'iconoclasme et reste vivante dans la période post-iconoclaste dans le conflit qui oppose le patriarche Ignace à Photios. (shrink)
