Wired has an interview with Lee Smolin.
Mel Schwartz died earlier this week. He won the Nobel prize in 1988 for his 1962 co-discovery of the muon neutrino at the AGS at Brookhaven. Schwartz left physics for a while and founded his own company near Stanford. He returned to Brookhaven and worked on the plans for RHIC, then came back here to Columbia where he was a professor in the physics department, so I had the pleasure of meeting him a couple times. After his retirement he moved to Idaho.
Freeman Dyson’s 1951 lectures on QED have been put in TeX and posted on the arXiv.
This fall Graeme Segal will be visiting Columbia as “Eilenberg Chair”, a visiting position we have that was funded by the sale of part of Sammy Eilenberg’s collection of South and Southeast Asian art to the Metropolitan Museum. Segal will be giving a course on The Mathematical Structure of Quantum Field Theories, which I’m very much looking forward to.
Another course I’d like to attend, but it’s too far away, would be Dan Freed’s one this semester on Loop Groups and Algebraic Topology. The web-site for the course includes a reproduction of Bott’s wonderful lecture notes dealing with the topology of compact Lie groups.
There’s a new paper out by Thomas Thiemann summarizing the technical state of LQG. I haven’t had time yet to read it, but hope to spend some time soon doing that. A good place to discuss it would be here, where Aaron Bergmann has already started, also see some comments by Robert Helling. A not so good place to discuss it would be here.
Eckhard Meinrenken has an interesting new paper entitled Lecture Notes on Pure Spinors and Moment Maps, which promises a more detailed forthcoming paper by him, Alekseev and Bursztyn.
