http://www.edge.org/q2008/q08_5.html John Baez: "I realized I didn't have enough confidence in either theory to engage in these heated debates. I also realized that there were other questions to work on: questions where I could actually tell when I was on the right track, questions where researchers cooperate more and fight less. So, I eventually decided to quit working on quantum gravity. It was very painful to do this, since quantum gravity had been my holy grail for decades. After you've convinced yourself that some problem is the one you want to spend your life working on, it's hard to change your mind. But when I finally did, it was tremendously liberating. I wouldn't urge anyone else to quit working on quantum gravity. Someday, someone is going to make real progress. When this happens, I may even rejoin the subject. But for now, I'm thinking about other things. And, I'm making more real progress understanding the universe than I ever did before." http://www.rehseis.cnrs.fr/recherche/0708/seminaires/physique0708.htm Responsables : Nadine de Courntenay, Olivier Darrigol , Sara Franceschelli, Jan Lacki. "L'étonnante diversité des descriptions théoriques utilisées dans la physique d'hier et d'aujourd'hui a souvent été perçue comme une faiblesse temporaire qu'il faudrait corriger dans un état plus avancé de cette science. Dans cette veine, Pierre Duhem comparait le progrès scientifique à une marée montante dont les vagues ne sont qu'un décor périssable. Les penseurs réductionnistes cherchent à éliminer cette diversité en dérivant tout phénomène de l'ontologie homogène d'une théorie plus fondamentale que les autres. Les structuralistes et les positivistes, quant à eux, s'efforcent d'identifier les structures universelles qui dominent nos modes périssables de description. Contrairement à ces deux attitudes, les héritiers de James Clerk Maxwell, Ludwig Boltzmann et Henri Poincaré soulignent les vertus épistémiques d'une diversité des descriptions et considèrent que décrire est un acte dont la dynamique transcende les objets originels de la description. Dans ce séminaire, nous proposons d'adopter cette seconde attitude....." Pentcho Valev pvalev@yahoo.com
