Lots of wonderful blog postings about math and physics out there worth reading, with a small sample including these:
From CERN, here’s a report from JoAnne Hewett about the summary session discussing the Chamonix workshop on the state of the LHC and plans for getting it up and running. The current schedule, which is tight, has collisions starting in November of this year, and running for nearly a year until late 2010. To accumulate an amount of data that would allow some significant new results (about 50pb-1) should take six months or so, until mid-2010. The hope is to get to 2-300 pb-1 later in 2010 before shutting down. This would not allow the LHC to do better than the Tevatron on the Higgs. For that, we’ll probably have to wait for data from the 2011 run. By the time this data is in, the Tevatron should have about 10fb-1 to analyze, and may already have seen evidence of the Higgs.
Also at CERN, there has recently been a conference on the topic From the LHC to a future collider. Lots of interesting talks about future possiblities, including the ILC, CLIC, colliding LHC protons with electrons, as well as the possibility of a muon collider.
More and more areas of mathematics have a blog, here’s one for motivic homotopy.
Bert Schroer has updated two of his long articles that discuss both the sociology and conceptual framework of quantum string theory: String theory deconstructed, is dedicated to Philip Anderson and has a new section about history of the subject in Germany, and String theory and the crisis of particle physics, which is dedicated to Juergen Ehlers.
I hadn’t realized that Physics World has a blog. Among the latest entries are two reports (here and here) about Lenny Susskind’s recent talk to 700 people in Bristol about Darwin and the Cosmic Landscape. Susskind is still at it selling string theory and the multiverse to the public, no matter how unconvinced his colleagues may be:
Just as there is a vast landscape of biological designs, our best theories of physics imply an equally vast landscape of universe designs. String theory provides an analogue of DNA for the universe and modern cosmology makes use of a principle of mutation that creates a tremendously large multiverse.
It seems that
The central tenet of Susskind’s talk was that string theorists should look to Darwin because he “set the standard for what an explanation should be like”.
Funny, I always thought it was physics itself which set such a standard for the biological sciences, but I guess the idea now is to give up on that and have them be the gold standard.
While many theoretical physicists in their later years try and go for the Einstein look, according to one of the Physics World bloggers, Susskind is doing a good job of looking like Darwin.
