In 1972, the future Nobel Prize winner Philip Anderson published an article in "Science" entitled "More is Different", in which he explained the concept of emergence in a remarkably clear manner: the behaviour of assemblies of interacting particles cannot be understood as a simple extrapolation of the behaviour of isolated particles. On the contrary, original and surprising behaviours can appear, and their understanding requires specific concepts and new tools. The whole is not greater than the sum of its parts, it is different. Anderson had in mind, in particular, the surprising collective behaviours in condensed matter systems such as superfluidity, which does not exist at the atomic level, and can only appear at the macroscopic level. This phenomenon of emergence concerns many fields outside physics: collective behaviour of neurons (memory, consciousness), starling murmurations, social unrest, economic crises, financial panics... I thought that a conference on this theme would be a perfect epilogue to my course on the links between statistical physics - which is precisely the science of emergence - and the social sciences. My hope is to bring together, on June 2nd and 3rd 2022 at the Collège de France, physicists, economists and mathematicians specialised in these ideas, to allow, who knows, the emergence of new research directions. https://lnkd.in/eG4Y4_9E#research #collective #emergence #crises #panic #collegedefrance
