Abstract The cutoff phenomenon is an abrupt transition from the non-equilibrium state to the equilibrium state undergone by certain Markov processes in the limit where the number of states tends to infinity. Discovered forty years ago in the context of …

Abstract The spirit of research is nourished as much by the sources of reality as by the labyrinths of the imaginary. Through rapid monologues, four archaeologists give us a glimpse of the forces that drive them to delve ever deeper into the deciphering …

Abstract This lesson explores recent advances in the field of biopolymers, in particular biomimetic and biohybrid polymers. Since ancient times, with materials such as rubber and silk, scientists have been striving to understand and imitate natural …

Abstract The snowpack that accumulates in the mountains every year is a precious natural water reservoir for humans, retaining winter precipitation and releasing it in spring at the right time to irrigate crops. What's more, the snowpack is a powerful …

Abstract Satellite Earth observation began a few years after the launch of the first artificial satellites. The first   instruments aboard these satellites were designed for imaging purposes, and were mainly used to visualize cloud systems. Soon, more …

Abstract This session explores the question of the universality of science. Even more than natural law or the language of civilization, isn't science at the heart of conceptions of the universal developed in the 18th century    ? To understand what is at …

Abstract We begin by demonstrating that, for a random hyperbolic surface of large genus, the spectral hole is close to 1/4, with probability tending towards 1. The "trace method" consists in controlling the spectral hole by the number of large periodic …

Abstract Context and vocalization make Hebrew one of the most polysemous languages. Readers of the Bible are constantly forced to make trade-offs: they have to accept misunderstandings, or rather misreadings , and the impossibility of a faithful, reliable …

Abstract In a world that has never seemed so dangerous, why read literature ? Many would say, including Pope Francis : to better understand this world, to better penetrate its reality. This is particularly true when we place ourselves under the realist …

Abstract Can the sociological and anthropological concept of patriarchy, which has become a fighting name in contemporary feminist struggles, be applied to the Middle Ages? You'd think so, given that the concept of paternitas semantically configures all …

Abstract One of the major frontiers of contemporary cosmology is to elucidate the nature of dark energy, responsible for a mysterious phenomenon  : the acceleration of the expansion of the Universe. The European Space Agency's Euclid satellite aims to map …

Abstract The Euclid satellite, launched in July 2023 by the European Space Agency, will observe a large part of the sky for six years, and identify more than ten billion galaxies at different epochs. It will use several tools, such as gravitational …

Abstract Desire seems to be characterized by two distinct features. On the one hand, desire motivates actions directed towards its object. On the other hand, to desire an object seems to mean to enjoy or appreciate it. Theories of desire are divided over …

Abstract Hammu-rabi of Babylon commemorated in the name of his 35th  year of reign the ruin of Mari, whose conquest he had celebrated two   years earlier. Paradoxically, this destruction was a stroke of luck for the historian : the collapse of the roof …

Abstract In the representation we end up with, concepts are like "nodes" in a conceptual network, and the relationships between nodes represent not only the analytical implications of concepts - the fact that red is a color, or that bachelors are …
