Slides from my talk at Rutgers are now available here. The idea was just to advertise to physicists there the point of view that is all too familiar to regular readers here. The final speculative comments about relations to mathematics … Continue reading ?
Not much time for blogging at the moment, with one reason that I’ll be giving a talk at Rutgers on Wednesday, and need to get that prepared. A few quick items: As some commenters have mentioned here, talks from the … Continue readin...
Joe Polchinski has a rather odd preprint on hep-th, more of a blog posting than a paper, summing up his views on string theory and the multiverse. This is a revised version, wisely dropping a really unfortunate section. The material … Continue reading ?
There’s a document out tonight on the arXiv from Joe Polchinski which makes various accusations against me. I’ve heard recently that he has been seriously ill, and am afraid that this has something to do with that. I’d urge people … Continue reading ?
I recognize that this is a genre that is a bit tired, and arguably in poor taste, but the commentary on the HEP theory postdoc job market in the video Hitler doesn’t get a postdoc in High Energy Theory is … Continue reading ?
It’s been a while since the last posting here, mostly because I’ve been away on vacation, but also because I haven’t seen anything that newsworthy. But, since I’m back in the office and there have been complaints, here are a … Continue reading ?
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 ?
