Renate Loll was co-organizer of a Gerard 't Hooft 60th birthday celebration Physics conference going on now on a pretty Dutch island Today 15 July, Lee Smolin and Carlo Rovelli gave talks Frank Wilczek was one of the speakers yesterday. The party lasts three days 14-16 July. http://www1.phys.uu.nl/gerard60/program/ I think the usual name for this kind of conference is "[name]FEST" like this one would be called "'t HOOFT FEST" =============== Renate gave the opening (welcome) talk yesterday. Later Frank Wilczek gave a talk about 3 candidates for dark matter. I guess 't Hooft is pretty interested in Quantum Gravity because several of the talks today seem to be QG. Tomorrow talks include some by famous string personages and by cosmologists: David Gross, Leonard Susskind, Andrei Linde, Lawrence Krauss there is a PDF printable version of the program incase anyone is interested. http://www1.phys.uu.nl/gerard60/program/program-full.pdf more Utrecht-related links here: https://www.physicsforums.com/showthread.php?t=77639 the 't Hooft-fest venue is a beach hotel one of the events is a barbecue, another is a picnic at the lighthouse.
