The Hymn " Homeric " to Demeter has been preserved as part of a collection of thirty-three hymnal pieces in honor of a whole series of divinities, whose hexametric form has associated them with Homer's name. Both the date and length of these poems vary. …

Abstract The centrality of schools The centrality of the school explains why the State and the Church were particularly interested in it during the period we're looking at. The former paid increasing attention to teaching, and for this reason was the …

Abstract Despite the rapid evolution in the development and deployment of machine learning methods in almost all areas of society, our theoretical understanding of the mechanisms behind this success remains rather limited. As discussed several times in …

Abstract The Shannon-MacMillan-Breiman theorem proves the asymptotic equipartition property in typical sets, as soon as the process is ergodic. The notion of ergodicity and Birkhoff's theorem are introduced, but not proved. The main argument of the proof …

Abstract Liquids are usually described within classical physics, whereas solids require the tools of quantum mechanics. I will show how in nanoscale systems this distinction no longer holds. At these scales, liquid flows may in fact exhibit quantum …

At nanometric scales, surface effects obviously become predominant. Wall friction effects play a key role, impacting all transport processes - fluid, ionic, etc. They originate in molecular friction at the interface between the fluid, e.g. water, and the …

Patrick Suppes is invited by the Collège de France assembly at the suggestion of Pr Anne Fagot-Largeault. …

Abstract Seventeenth-century authors   say almost nothing about their own writing practice or their conception of their work, even though it was during this period that the advent of the author took place. This is because writing is linked to the …

Abstract Valéry's schema of the two   mountains presupposes a hierarchy between works, according to the degree of exigency they carry. From this stems an essential problem  : how do we know what type of aesthetic requirement is carried by a work  ? What …

Religion is most often studied through the lens of official worship. We'll be looking at the intimacy of families, observing domestic spaces reserved for worship (" chapels ") and family devotions through the legends of cylinder …

Interactions between species in nature can lead to fluctuations in population sizes, as for example in a two-species predator-prey system. What dynamical behavior should we expect when many species are involved, as is often the case in nature? I will …

Abstract From intragenomic conflicts to mutualistic symbioses, biological interactions invite us to question the foundations of a rarely-explained concept that is nonetheless essential to Darwinian reasoning : the individual. The individual as " level of …

The machine metaphor does not apply well to living elements. Every cell derives from a cell. Every living thing derives from another living thing. The future dynamics of an ecosystem can only be understood in the light of its past history. Synthetic …
