Abstract This lecture will focus on the paradox of invasions : biological invasions are particularly important, yet little recognized, or even simply known. We will discuss the reasons for this, exploring society's perception of biological invasions, …

Lecture outline: exact modalities left; application to the construction of new type-theoretic models; unprovability of Church's thesis and countable choice; Quillen model structure and constructive model of the notion of homotopy types. Documents and …

Abstract Data assimilation is the set of key mathematical methods used to optimally combine observations and numerical model outputs. Data assimilation (DA) is critical to adjust the initial condition of meteorological forecasts, to estimate model …

Abstract The stunning recent advances in AI content generation rely on cutting-edge, generative deep learning algorithms and architectures trained on massive amounts of text, image, and video data. With different training data, these algorithms and …

Abstract This presentation will cover some of the recent advances in weather forecasting, learning directly from data using machine learning techniques. It will discuss some of the limitations and pitfalls of training ML models for scientific …

Abstract While AI has been disrupting conventional weather forecasting, we are only beginning to witness the impact of AI on long-term climate simulations. The fidelity and reliability of climate models has been limited by computing capabilities. These …

Abstract Mathematical and numerical models of the atmosphere and ocean rely on various assumptions, approximations, and simplifications. Over the past decade, significant progress has been made in elucidating their structure and interconnections, …

Abstract I will discuss the Neural GCM, which we built by building a dynamical core in JAX and then training the parameterization on ERA5 on 5-day forecasts. The quality of the forecasts up to 1 year portends a potential revolution in improving model …

Abstract Sharp structures can occur as minimizers of very regular problems. This means symmetry can lead us badly astray and the resultant symmetry breaking may lead to highly counter-intuitive structures. I will illustrate in a discrete example and then …

Abstract The control of irrigation by a bureaucratic apparatus linked to religious and/or state power is at the heart of social theories that have marked the history of ideas over the last one hundred and fifty years. Although largely discredited, they …

Abstract What a strange thing it is to have as a profession that of acting ! While theater addresses a collective body, present here and now, in a form that will never be reproduced identically, cinema seeks to create the intimate, reproduced and diffused …

Abstract Joint work with Dalina Kallulli, University of Vienna. Since the 1980s, the generative theory of cross-linguistic variation has relied on the notion of parameter of Universal Grammar, according to which universal properties of language are …

Abstract In his book Les Atomes (1913), Jean Perrin identified one of the fundamental characteristics of the scientific process as the attempt to "   explain the complicated visible by the simple invisible   ". This characterization fits perfectly with …

Abstract The project about the Persian manuscripts of Sir William Ouseley (1767–1842) and his brother Sir Gore Ouseley, bt (1770–1844) explores how after 1757 the increased British demand for literature about Mughal India changed the international …

Liam Murphy is invited by the assembly of the Collège de France, on the proposal of Pr   Samantha Besson. As part of the agreement signed between Collège de France and New York University. Frontispiece to Thomas Hobbes' "Leviathan" (1651). Public domain. …

Abstract Marc Fontecave will briefly describe the background to the Avenir Commun Durable chair, which he helped create and which is hosting this …
