21/04/2022 – Gilles Cohen-Tannoudji and Jean-Pierre Gazeau : From Lemaître’s primitive atom to the Higgs boson, the challenge of a scientific cosmogony may be about to be met.

Thursday the 21st of April, at 15:00 Paris time (CET), at this Zoom link


In his 1946 book The Primitive Atom Hypothesis – Essay on Cosmogony (currently being republished), Georges Lemaître, Catholic priest and eminent scientist considered as the father of modern cosmology, challenges a scientific cosmogony that stands out from pre-scientific, mythological or theological cosmogonies. Is this challenge about to be met thanks to recent advances in observational astrophysics and the epistemology of quantum physics? That’s what we think and what we try to convince you of.

Biographical information:

Gilles Cohen-Tannoudji, after having spent his entire career at the CEA, since 1962, as a theoretical physicist in particle physics, is currently a researcher emeritus at the Laboratory for Research on the Sciences of Matter (LARSIM CEA-Saclay) and is interested in cosmology and in philosophy of science. He has recently published:

Jean-Pierre Gazeau is emeritus professor at the Université Paris Cité, France, a member of the Astroparticle and Cosmology Laboratory (CNRS, UMR 7164). He is associated researcher at the mathematical physics laboratory of the Centre de Recherches Mathématiques, U. Montreal, and invited researcher at the Centro Brasileiro de Pesquisas Fisicas, Rio de Janeiro (CBPF). He was Chairman of the Standing Committee of the International Colloquium on Group Theoretical Methods in Physics (ICGTMP) from 2006 to 2014. Professor Gazeau research focuses on theoretical and mathematical physics, and is mostly devoted to group theoretical methods in physics, coherent states, quantization methods, and number theory for aperiodic systems. Among the most recent published work:
