De Maistre à Jacques Vier, en passant par l'abbé Bremond, Mgr Calvet, l'abbé Baudin et le cardinal Journet, par Massis, Bourget, Maritain, Goyau, Maurras et bien d'autres, l'auteur a enquêté. Et il faut l'admettre, le Pascal des paroissiens correspond rarement au Pascal historique: "... il y a chez Pascal une critique sociale et politique [...] qu'il serait à peine exagéré de dire qu'aucun des théoriciens du XVIIIe siècle ne l'a seulement rejointe," écrit Goldschmidt. Son génie a contribué à introduire dans (...) la pensée des catholiques les éléments de la modernité politique qui étaient la condition préalable de sa destruction, résultat inespéré du jansénisme, dont nous sommes si imprégnés que nous le voyons plus. Alors, que reste-t-il de Pascal?"--Page 4 of cover. (shrink)

The author begins by recalling how he was led in 1923–24 to the ideas of wave mechanics in generalizing the ideas of Einstein's theory of light quanta. He made himself at that time a concrete physical picture of the coexistence of waves and particles and, in 1927, attempted to give them precise form in his “theory of the double solution.” As other ideas prevailed at the time, he abandoned the development of his conception. But for the past twenty years, once (...) again convinced, like Einstein, that present-day quantum mechanics is only a statistical theory and does not give a true picture of physical reality, he has again taken up his old ideas and developed them considerably. He has in particular introduced an element of randomness into the theory and has thus attained to a “hidden thermodynamics of particles,” the results of which appear to be very interesting. (shrink)

The general properties of measurements in microphysics are studied and the three types of probabilities that, according to the authors, appear in wave mechanics are set up. Such a distinction, together with the principle of the localization of the corpuscle as was laid down at the very introduction of the theory of the double solution, provides a good grasp of certain phenomena whose explanation according to the usual theory (which makes no use of permanent localization and where the three types (...) of probabilities are intermingled) leads to paradoxical or self-contradictory situations.

RésuméAprès avoir rappeléľorigine et le sens de la notion de compleAmentarité introduite par Bohr en Physique quantique et avoir fait allusion aux diverses extensions qui en ont déjàété proposées, ľauteur cherche à appliquer ľidée de complémentarité aux relations qui existent entre les constituants ?un système et le système entier. La perte ?individualité subie par les constituants ?un système et traduîte en Mécanique classique par la notion ?énergie potentielle s'accentue au fur et à mesure que la liaison des constituants dans le (...) système devient plus étroite. Ľétude de la mécanique ondulatoire des systèmes confirme ľidée qu'il existe une sorte de complémentarité entre ľidée de constituant autonome et celle de système. L. de B. (shrink)

Les troubles de mémoire sont un motif fréquent de consultation dans les services de gériatrie, psychiatrie ou neurologie. Ils sont pour beaucoup synonymes d’un mot terrible : Alzheimer. Dès l’apparition de troubles mnésiques, chacun s’interroge : « Est-ce l’âge, ou bien la maladie? Puis-je panser ma mémoire, ou vais-je dériver avec elle? » Les docteurs Emmanuelle Candas et Bruno Le Dastumer, gériatres, spécialistes des troubles de la mémoire, font un état des lieux de la maladie d’Alzheimer et répondent à ces (...) interrogations : comment faire la différence entre le vieillissement naturel du cerveau et les troubles mnésiques pathologiques? Existe-t-il un traitement pour soigner la maladie d’Alzheimer? Et surtout, comment accompagner le malade, dès le diagnostic établi? (shrink)

Certain difficulties raised by Einstein and Schrödinger in connection with the quantum theory of radiation are discussed and resolved in terms of the author's theory of the double solution.

What determines if the first interaction between strangers will be a pleasant experience? We conducted an experiment to investigate the extent to which the perceived quality of an interaction is influenced by conversation content and context, and we document the physiological changes that are likely to play a role in establishing rapport. Females who did not know each other met in pairs and conducted a gossip- or creativity task, either face-to-face or online. The conversation content had no effect on the (...) quality of online interactions. However in the face-to-face condition gossip was associated with better interaction quality. Tonic electrodermal activity steadily declined throughout the interaction, while phasic electrodermal activity first peaked and then returned to baseline. Neither were related to perceived interaction quality. Heart rate variability dropped at first but then remained stable. A smaller drop in HRV drop corresponded to higher ratings of rapport and liking. Together these results suggest that gossip can improve the quality of a face-to-face interaction between strangers, and support the conjecture that parasympathetic activity is a marker of human openness to social engagement.
