This morning in Geneva saw the first collisions in the revamped LHC, there’s an event display from ATLAS here, CMS here. These collisions are just at the injection energy of 450 GeV/beam, but over the past few weeks beams have … Continue reading ?
I’ve written a review for the Wall Street Journal of Paul Halpern’s new book Einstein’s Dice and Schrödinger’s Cat (It’s here, unfortunately now behind a paywall). I liked the book quite a bit, and learned many things about some history … Continue reading ?
John Horgan has an interesting interview with Steven Weinberg here. Weinberg isn’t very optimistic about possible progress these days: Horgan: In 1995 you told me that it’s a “terrible time for particle physics.” Are you feeling any better about your … Continue reading ?
I’ve been busy with other things, but after taking a look today at various new things related to quantum gravity, I was struck by how much things have changed sociologically in that subject over the last few years. Back in … Continue reading ?
Cédric Villani is in town today, giving a talk at the French consulate. He’ll discuss his book, recently translated into English (I wrote a bit about it here). Yesterday, despite the lack of suitable bread and cheese, he was in … Continue reading ?
The LHC has just ramped up for the first time to 6.5 TeV, and has a probe beam circulating in one direction, the highest energy protons humans have ever accelerated. You can follow what’s happening here. The BBC has gotten … Continue reading ?
Just about ten years ago, my April 1 posting here was a fantasy about the Stanford ITP getting major funding from the Templeton Foundation, using it to fund a program on the multiverse, and renaming themselves the Stanford Templeton Research … Continue reading ?
Some news from all over: The problem with a short in the LHC seems to have been resolved (one can follow progress here), looks like they’ll be ready to inject a beam in a few days. Also looks like they’re … Continue reading ?
Clouds cleared about 15 minutes too late at Torshavn in the Faroe Islands, so totality was behind a cloud, but still an impressive sight. And the Faroe Islands are quite a remarkable place to visit. Some recent news: The plan … Continue reading ?
I’m heading off soon on spring break, planning on traveling to Scandinavia and hoping to see a solar eclipse. There hasn’t been much news recently from the math and physics worlds, and it’s unlikely I’ll be blogging until I get … Continue reading ?
I hadn’t thought until recently about the fact that this year is the 100th anniversary of Einstein’s discovery of the field equations of general relativity, so there will be quite a few events taking place commemorating this (for a list … Continue reading ?
The LHC is getting close to the point where it can be restarted with a 6.5 TeV beam energy. Latest news here, schedule here. Plan is for a sector test late next week (beam in part of the machine), beam … Continue reading ?
A quarter-century or so ago, one of common arguments for string theory research was that it was “the only game in town”, in the sense that it was the only possible way to get a unified theory. For instance, back … Continue reading ?
A draft of an essay I’ve written, with plans to submit it to the FQXI essay contest, is available here. Constructive comments welcome…
Lee Smolin has a new book out last month, co-written with philosopher Roberto Unger, entitled The Singular Universe and the Reality of Time. To get some idea of what he’s up to, there’s a review by Bryan Appleyard at The … Continue reading ?
Peter Orland has a new blog, Ensnared in Vacuum, where he’s writing about some non-perturbative QFT questions. Physics Today this month has book reviews of two books about theology and the multiverse (one of which I wrote about here). There … Continue reading ?
I recently heard from Hirosi Ooguri that a transcript of a long conversation with Witten held at the time of his Kyoto Prize award has just appeared in the Kavli IPMU Newsletter. It’s a truly fascinating document, giving some great … Continue reading ?
Long awaited data from the Planck satellite was released today, papers available here. The accompanying press release leads with results about the timing of the first stars, 500 million years or so after the big bang, with little mention of … Continue reading ?
Leonid Reyzin at Boston University has drafted a letter in response to the recent article published in the Notices by Michael Wertheimer of the NSA (discussed here). He’s collecting signatures, and if you’re a member of the AMS I urge … Continue reading ?
Science magazine this week has an article and a podcast about the NSA and the AMS. AMS president David Vogan is portrayed as outraged at the NSA’s misuse of mathematics, but without much support for doing anything about it: But … Continue reading ?
