There are two new particle theory blogs that I’ve noticed recently: Shores of the Dirac Sea, where David Berenstein and Moshe Rozali are blogging and the Physics Anti-Crackpot Blog, by an anonymous author at CERN. I don’t know who this last blogger is, but he joins his (or her) colleague Jester at Resonaances (who is anonymous, but not hard to figure out) in skepticism about supersymmetry. Maybe things at CERN-TH are such that anonymity is a good idea if you hold such opinions….
Also at CERN, news of progress on the LHC commissioning is here. It seems that after some initial quick successes, there’s no beam at the moment as they fix various problems with the machine.
Frank Wilczek doesn’t have a blog (although his wife Betsy Devine does), but he does now have a web-site, as well as another web-site for his new book The Lightness of Being. Here’s a summary of the book, and a sample chapter, which gives you an idea what he’s trying to do with the book.
The Harvard physics department now is running a video archive. It includes video of their recent Colloquia, Loeb lectures, and Sydney Coleman’s quantum field theory course.
Update: There seems to have been some sort of problem in Sector 34 triggered by powering tests for operation at 5 TeV. This caused a large helium leak in the tunnel, an investigation is under way. More here.
Update: The news from the LHC is pretty bad. A failure during a powering test will require warming up the entire sector to fix the problem, then cooling it back down. This means that it will be another two months before beam commissioning efforts can start again, likely pushing physics collisions off until next spring, after the winter shutdown. There’s a press release here.
