Various and Sundry

The online magazine Smashpipe has the first part of a two-part article written by Gerald Alper, who recently came up here to Columbia to talk to me about string theory/etc. It was an interesting conversation, so I’m curious to see … Continue reading ?

Yet More About Grothendieck

Since Grothendieck’s death somewhat more than a year ago, quite a lot of new material about him and his mathematics has become available. Visit the Grothendieck Circle to find a lot of this, with just one example some new chapters … Continue reading ?

This Week’s Hype

This week’s dramatic announcement of the discovery of gravitational waves was a major milestone for the fields of physics and astrophysics. The LIGO observation validates a lot of previously untested aspects of our understanding of general relativity, and promises the … Continue reading ?

Gravitational Wave Predictions

I think I can confidently predict that tomorrow morning either one of two things will happen: The first observation of gravitational waves will be reported by the LIGO experiment. A large fraction of the scientific community will be really, really … Continue reading ?

Stacks Project Party

Last night I got to attend a major event of the Manhattan social season, a party celebrating the fact that the Stacks Project has reached the milestone of 5000 pages. As far as anyone knows, no one has ever printed … Continue readin...

Rutgers Talk

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 ?

Some News

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...

More From Polchinski

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 ?

Some History

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 ?

Hitler doesn’t get a postdoc in High Energy Theory

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 ?

Back at Work

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 ?

Various and Sundry

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 ?

End of Year Links

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 ?

Why String Theory?

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 ?

Updates

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 ?

Run 2 and SUSY

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 ?

LHC Run 2 First Results

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 ?

White Smoke Over Oxford?

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 ?

Today’s Hype

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’s Hype

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 ?
