Abstract At very low temperatures, the motion of atoms can no longer be described by the classical laws of Newtonian mechanics, but instead follows those of quantum mechanics. Atoms in some gases lose their identity. Thus, in Bose-Einstein condensation …

One of the characteristics of genius, as it is often portrayed in commentaries, is that it has no self-knowledge and is incapable of self-explanation. What we know of genius therefore comes, for the most part, from the observations of another who is …

Abstract Challenges are proposed by public services, companies or scientific laboratories, and are based on real-life problems. Participants submit the results of their classification or prediction algorithms, which are then put into competition via the …

Abstract Classification problems can be modeled either deterministically or probabilistically. These two approaches differ in the way they represent a priori information. In high dimensions, stochastic models often offer finer representations of data, …

I will explain why climate change is, historically, probably the greatest market failure. I will show how a carbon price can realign the myriad of private interests with the general interest, while achieving the goal of reducing emissions at the lowest …

Abstract Radio astronomy is in the process of acquiring new-generation radio telescopes, in anticipation of the SKA (Square Kilometer Array). In Nancay, there are LOFAR stations, and recently a NenuFAR station, with metric or decametric wavelengths. The …

Abstract Fast radio bursts have been observed regularly since 2007. Recently, it has been possible to localize them thanks to the repetition of some of them. They are thought to be caused by neutron stars, and even stars with intense magnetic fields - …

Hosted by Catherine de Coppet. Questioning the concept of adaptation in relation to the law opens up perspectives for reflection at the crossroads of ancient and contemporary law : has the law shown, in its history, a capacity for adaptation ? Is …

Hosted by Caroline Lachowsky. Demographic history, social and cultural factors and biological forces, such as the selection pressures exerted by changing environments (climatic, nutritional, pathogenic, etc.), have all had a major impact on the genome …

Hosted by Caroline Lachowsky. The history of human societies can be a source of inspiration in the face of climate change. Indeed, the long history of humanity is a perpetual story of adaptation and resilience, with its examples of both success and …
