What is infinity ? Throughout history, mathematicians have tried to give a precise meaning to this concept. Interview with mathematician Jean-Paul Delahaye, Professor Emeritus, University of Lille. "Pour la Science" dossier No 125

Compliance Robotics, a start-up resulting from the research work of the DEFROST team (CO2 Group in the CRIStAL laboratory), housed at Inria, has been awarded the i-Lab 2024 Grand Prize, a prestigious award given to just 10 innovative start-up projects in France. Compliance Robotics is one of the 2 …

From the "mutilated chessboard" to exotic assemblies of small squares, the question of which shapes are "dominable" is gradually being resolved, but not without difficulty. Jean-Paul Delahaye "Pour la science" article no. 564

To carry out certain operations, surgeons already have robotic tools at their disposal. But in the future, the implants themselves could be mobile, and controlled in such a way as to faciliate their insertion. The Robocop project, coordinated by Inria's Defrost project team, is a first step in the …

Recent research has taken up and refined the reasoning of the Swedish philosopher Nick Bostrom who, twenty years ago, thought it likely that our reality was in fact a computer simulation run by an advanced civilisation. Jean-Paul Delahaye POUR LA SCIENCE N° 563
