- First test collisions at 6.5 TeV/beam at the LHC are tentatively scheduled for Thursday morning.
- At CERN today there’s a workshop about the Higgs Machine Learning Challenge.
- Also on the topic of LHC data analysis news, Tommaso Dorigo announces the award of a grant for the AMVA4NewPhysics project.
- Sabine Hossenfelder has a review, slideshow and discussion of the Dawid book on “String theory and the scientific method” (which I wrote about here and here).
Much of the discussion is about the “No Alternatives” argument, but at this point I don’t even see how it applies here. The Landscape shows that string theory unification is a failed program, which rules it out. As for whether “gravitation is due to the spin two massless mode of a superstring” is the only alternative, these days my impression is that many prominent theorists are pursuing alternatives, that gravity is supposed to be an “emergent” phenomenon coming from something else.
- For those sticking to the 1984 point of view though, there’s a workshop on some interesting mathematics that’s part of that story (super geometry, super moduli spaces) going on at the Simons Center.
- Last week on Jeopardy (see here), no one got this question:
Nima Arkani-Hamed is using this number dimension, the next one beyond time, to rock the physics world.
I wouldn’t have either…
- For a bit of mathematics history, you might want to read Beilinson on Gelfand’s seminar.
- Natalie Wolchover at Quanta keeps on coming up with interesting physics stories not seen anywhere else, last week covering news about ultra-high energy cosmic rays.
Update: Successful test with first collisions at 13 TeV this morning at the LHC, see here.
