Cinq propositions pour appréhender le temps
Ce bref essai tente de dĂ©gager un certain nombre de caractĂšres communs DU temps, considĂ©rĂ© comme catĂ©gorie gĂ©nĂ©rale de « lâĂȘtre » des humains. Ă ce titre, il se sĂ©pare dĂ©libĂ©rĂ©ment de la tradition gurvitchienne, et de la mĂ©thode sociologique DES divers « temps sociaux ». Cinq entrĂ©es sont ici proposĂ©es :- La spĂ©cificitĂ© du temps dont les humains ont lâexpĂ©rience par rapport Ă lâespace- Le rĂŽle majeur du triptyque prĂ©sent-passĂ©-avenir (dans cet ordre)- La capacitĂ© DU temps Ă transcender les diverses « cultures du temps » comme donnĂ©es anthropologiques- Lâapparentement (« homologique ») entre temps social et temps personnel, comme prenant le pas sur lâirrĂ©ductibilitĂ© singuliĂšre du temps personnel- LâunitĂ© ultime entre le temps-englobant comme devenir gĂ©nĂ©ral et continu (dit « temps-compagnon »), et le temps inscrit (dit « temps-paramĂštre ») en tant que fractionnable et mesurableThis brief essay attempts to delineate some characteristics of time as such, seen as a general category upon which the existence, the « Sein », of human beings, rests. Consequently, it deliberately departs from the tradition established by the sociologist Georges Gurvitch and the sociological method based on the diversity of « social times » (temps sociaux). Five major points are outlined here:- the specificity, as experienced by human beings, of time vs. space.- the foremost relevance of the present-past-future trilogy (in that order).- the ability of time as such to transcend the diversity of « time cultures » as a cluster of anthropological constructs.- the close parallel between social time and personal time, this homology taking precedence over the intimate singularity of personal time.- the ultimate unity between two opposite versions of time, i.e. time as an all-embracing entity, a general, continuously moving force, and on the other hand time as a measurable, fractionable quantum, inscribed in our social existences. The former should be considered as a companion from whom we cannot part throughout the course of our existence, and the latter as a parameter we must deal with when organizing our lives
Non-equilibrium beta processes in superfluid neutron star cores
The influence of nucleons superfluidity on the beta relaxation time of
degenerate neutron star cores, composed of neutrons, protons and electrons, is
investigated. We numerically calculate the implied reduction factors for both
direct and modified Urca reactions, with isotropic pairing of protons or
anisotropic pairing of neutrons. We find that due to the non-zero value of the
temperature and/or to the vanishing of anisotropic gaps in some directions of
the phase-space, superfluidity does not always completely inhibit beta
relaxation, allowing for some reactions if the superfluid gap amplitude is not
too large in respect to both the typical thermal energy and the chemical
potential mismatch. We even observe that if the ratio between the critical
temperature and the actual temperature is very small, a suprathermal regime is
reached for which superfluidity is almost irrelevant. On the contrary, if the
gap is large enough, the composition of the nuclear matter can stay frozen for
very long durations, unless the departure from beta equilibrium is at least as
important as the gap amplitude. These results are crucial for precise
estimation of the superfluidity effect on the cooling/slowing-down of pulsars
and we provide online subroutines to be implemented in codes for simulating
such evolutions.Comment: 11 pages, 6 Figs., published, minor changes, subroutines can be found
