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 We know of two major cities in Roman Corsica, the colonies of Aleria and Mariana, which fell into disuse rather suddenly, and whose ruins are now buried under acres of meadows. A few shipwrecks dot the coastline, reflecting the intense trade that …

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 This seminar will illustrate how modeling the Earth system helps us to understand the climatic changes our planet has undergone over its long history. In particular, we'll look at the principles that regulate temperatures and the hydrological …
