Before I turn to the main topic of this posting, a lecture by Jacob Lurie, I’d like to point to something else involving him, a comment and posting at Mathematics Without Apologies, a blog you should be following anyway. On … Continue reading ?
I know I should be coming up with material on different topics here, but the multiverse stuff sometimes is just too hard to ignore. Next week’s Comicpalooza in Houston will feature string theorist Gerald Cleaver. His blurb tells us that: … Continue reading ?
Apologies for too much recent posting here about the tired topic of the string wars. I hope to soon make amends by writing about something new I learned about geometric Langlands. The summer 2015 issue of Perspectives in Science has … Continue reading ?
Aeon magazine has just published a long piece on the current state of cosmology by Ross Andersen. One focus is on Paul Steinhardt and his claims that the popular multiverse/eternal inflation scenario doesn’t explain what it is supposed to, and … Continue reading ?
The science magazine Nautilus this month has a profile of me, under the title The Admiral of the String Theory Wars. The writer, Bob Henderson, spent a lot of time talking to me and other people around here, including attending … Continue reading ?
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 ?
