François-Marie Bréon
Clouds : regulators or amplifiers of climate change ?
Lecture
Event
Abstract Clouds have a major influence on climate balance. On the one hand, they reflect part of the sun's radiation back into space  ; on the other, they contribute to the greenhouse effect. These two   processes have broad but opposing impacts on the …

Syntax mapping and its interfaces with phonology and semantics
Luigi Rizzi, chair General Linguistics
Lecture
Series
Human languages allow the creation of an unlimited number of messages. Syntactic Combinatorics is at the root of this remarkable property. Through the recursive application of simple Combinatorics rules (perhaps just one very general rule  ! ), we can …

Nalini Anantharaman
Topological recursion and consequences (continued)
Lecture
Event
Abstract We have completed the demonstration of Mc Shane's formulas, generalized by Mirzakhani. These are remarkable geometric identities, valid on any hyperbolic surface with an edge, relating the lengths of the edges of the "hyperbolic pants" contained …

The notion of "substitute cult". Reflections on ritual mechanisms in ancient Egypt
Seminar
Event
Abstract The study of various examples of "   substitution cults   ", particularly in the Osirian domain, leads us to question the rules of ritual practices and their constants in ancient Egypt. This phenomenological approach provides a clearer picture of …

Solutions to Monitor Plants, Pollinators and Their Interactions in a Changing World
Emmanuelle Porcher, chair Biodiversity and ecosystems
Symposium
Series
Plant-pollinator interactions, which play a central role in the functioning of all ecosystems, including in farmland, are likely to be greatly altered by global change, but these changes remain poorly understood because they are often studied in …

Julien Lavalle
New particles and indirect detection
Seminar
Event
Abstract Our understanding of current cosmological observations and the formation of the great structures of the Universe (galaxies and beyond) is based in part, in the standard cosmological model, on the existence of an effective fluid of cold dark …

Françoise Combes
Possible candidates for dark matter
Lecture
Event
Abstract There are several cosmological constraints for finding candidates, coming from galaxies, clusters, but also constraints from quantum physics, fermions or bosons. Particle physics points to a wide variety of candidates   : weakly interacting WIMPS …

Ecological Minds
Guest lecturer
Event
Abstract Humans and other animals have minds because reality is predictable. The world is full of items that behave in regular ways. Our minds lock onto these items so that we can anticipate events and act accordingly. The central role of thoughts is thus …

Optimum control of a punctual process of unknown intensity
Seminar
