Some short items on a wide variety of topics: The Hawking/Perry/Strominger paper on a new idea about the black hole information paradox (see here for an early discussion) based on BMS supertranslation symmetries has now appeared on the arXiv. I’m … Continue reading ?
A collection of links to round out the year: The Seminaire Bourbaki talks this January look unusually interesting. Luckily I’ll be in Paris at that time. For an end of year present, Jacob Lurie has posted a version of his … Continue reading ?
I recently got a copy of Joseph Conlon’s new book Why String Theory? and was pleasantly surprised to find that it’s quite good. Conlon is a lively, entertaining writer, generally sensible about the scientific issues involved, and I think does … Continue reading ?
Some new items mostly updating older ones: Natalie Wolchover has a very good article at Quanta, entitled A Fight for the Soul of Science, reporting on the recent Munich conference discussed here. David Gross sounds a little bit like John … Continue reading ?
What surprised me most about today’s Run 2 results (see here) was that CMS and ATLAS were able to already significantly push up limits on superpartner masses, especially the gluino mass. Limits on the gluino mass went from 1.3-1.4 TeV … Continue reading ?
First results using the full data from Run 2 at 13 TeV will be presented tomorrow at CERN at 15:00 Geneva time, with a live webcast available here. For some relevant commentary, see Tommaso Dorigo and Matt Strassler. Among relatively … Continue reading ?
I’ve stolen the title of this posting from Michael Harris, see his posting for a discussion of the same topic. A big topic of discussion among mathematicians this week is the ongoing workshop at Oxford devoted to Mochizuki’s claimed proof … Continue reading ?
Joe Polchinki’s contribution to the ongoing Munich meeting has now appeared on the arXiv, with the title String Theory to the Rescue. Evidently he’s not actually to be at the meeting, I’m not sure how his paper will be presented. … Continue reading ?
Next week there will be a workshop in Munich with the title Why Trust a Theory? Reconsidering Scientific Methodology in Light of Modern Physics. It’s organized by Richard Dawid, to discuss his ideas about “non-empirical theory confirmation”, developed to defend … Continue reading ?
I’ve recently finished reading two new books on huge collider projects, which make an interesting contrast. The first is From the Great Wall to the Great Collider, by Steve Nadis and Shing-Tung Yau. It’s a very well-informed and topical book, … Continue reading ?
A few quick items before the holiday: I hear that Luis Alvarez-Gaumé will be the next Director of the Simons Center, starting next Fall, taking over from John Morgan, the founding Director. My understanding is that the hope was to … Continue reading ?
Since I often post here complaints about articles produced by the press offices of various institutions that hype in a misleading way physicist’s theoretical work, I thought it a good idea to make up for this by noting a positive … Continue reading ?
There’s an interesting development in the math-physics overlap, with a significant number of physicists getting interested in the theory of automorphic forms, often motivated by the problem of computing string scattering amplitudes. This has led to a group of them … Continue reading ?
This week’s string theory hype comes to us from USC physicists Clifford Johnson and Nick Warner, courtesy of the USC press office (see here and here). It’s garden variety hype of this kind, exactly the same claims about strings and … Continue reading ?
The 2016 Breakthrough Prizes were announced last night, discussed a bit in the last posting. Today there are programs going on at Berkeley, livestreams available here. One thing that strikes me about these things is that the situation with the … Continue reading ?
Later tonight will be the 2016 Breakthrough Prize ceremony, broadcast live on the National Geographic channel. While mathematicians and physicists are getting their popcorn ready, waiting to find out which of their colleagues will be $3 million richer, they might … Continue reading ?
The string wars seem to still be going on, with the latest salvos coming from Ashtekar and Witten. In a very interesting recent interview, at the end Ashtekar has some comments about string theory and how it is being pursued. … Continue reading ?
I’m pressed for time, heading out tomorrow for a short vacation in San Francisco, but I did want to write a little bit here before leaving. Last year around now, a theme was Hollywood blockbuster films with physics/math themes, this … Continue reading ?
The field of hep-th has always been quite faddish, with many of the fads easily recognizable just from looking at the buzzwords appearing in paper titles. In recent years “entanglement” is a buzzword that has been all the rage, and … Continue reading ?
There will be an awards ceremony November 8 for the 2016 Breakthrough Prizes, hosted by Seth MacFarlane, and airing live on the National Geographic Channel, later to run on FOX. The next day at Berkeley there will be a Breakthrough … Continue reading ?
