Lee Smolin’s forthcoming book “The Trouble With Physics” has a web-site.
There’s a new group blog focusing on n-categories, The n-Category Cafe, which will be run by John Baez, David Corfield and Urs Schreiber. It looks like Urs will basically be moving operations from The String Theory Coffee Table to this new blog.
The August issue of Symmetry is out. Lots and lots of articles about the LHC.
For the past week and a half Fermilab has been hosting a summer school on physics at Hadron Colliders. The talks are available here, and many are quite interesting. For example, history buffs should look at the talks on the top discovery by Tollefson and Varnes, and there’s a nice survey talk by Chris Hill in which he emphasizes the role of symmetries. Hill notes that unification of couplings in the MSSM doesn’t quite work, off by 3 sigma in the prediction of the strong coupling constant. He describes supersymmetry as “our best operational hypothesis” but believes that “It (probably) won’t be the MSSM!!!”.
The Telegraph seems to have tracked down Perelman and has an article about him entitled World’s top maths genius jobless and living with mother. It claims that Perelman is not going to the ICM, where it is assumed he will be awarded the Fields medal, because he can’t afford the trip. It also claims that in 2003 he was not re-elected to the Steklov institute and forced to leave. I find lots of things in the article hard to believe, remarkable if they’re true.
The rumor is that this week’s New Yorker, on the newstands tomorrow, will have a long article by Sylvia Nasar (author of the Nash biography, “A Beautiful Mind”) about the Poincare Conjecture and Perelman’s proof.
Last month the IHES held a conference on motives. Many lectures and references are now available here.
The IHES web-site also has a preprint of a new survey article by Pierre Cartier entitled A primer on Hopf algebras.
This summer’s Park City program was on the topic of Low Dimensional Topology. Some lecture notes are available here. These include notes taken by Gabriel Drummond-Cole, who also has lots of other notes from interesting talks and lecture courses.
Update: The New Yorker article, by Sylvia Nasar and David Gruber, is called “Manifold Destiny” and is in this week’s issue, but not available on-line.
The ICM is starting tomorrow, with video of talks available here. There seem to be four lecture slots scheduled for lectures by Fields Medalists, I’m deeply embarassed that I still haven’t heard reliable rumors about who they all are. There have been solid rumors identifying Tao and Perelman, of the less solid ones retailed here, Bhargava sounds to me the most plausible. I guess we’ll know soon….
Update: The New Yorker article is now available on-line.
