The LHC has now finished the first part of its physics run at 13 GeV, with intensity ramping up more slowly than hoped. Total luminosity/experiment so far is about.1 inverse fb (see here), about a tenth of some earlier … Continue reading ?
Over the years the NSF has financed various summer camps for high school students, designed to get them interested in mathematics or other areas of science. This summer they’ve teamed up with the NSA to deal with the problem of … Continue reading ?
When I was young, I recall that a standard assignment when restarting school was an essay on “what I did on my summer vacation”. Now that I’m back in the office after a vacation, here’s a version of that, covering … Continue reading...
Heading out soon for summer vacation travels, this time to Ireland and France, back in about two weeks. While away comments will be shut off. My vacation will spare readers commentary on the rest of the Strings 2015 talks, which … Continue reading ?
Some of the talks at Strings 2015 have now appeared online, and one of them I found quite fascinating, Witten’s Anomalies Revisited. Some of his motivation comes from string perturbation theory and M-theory, but the questions he addresses are fundamental, … Continue reading ?
Another conference that starts today is the Convergence conference at the Perimeter Institute. The concept is explained by Neil Turok here. His point of view is one I’m very much in sympathy with: Turok explains that the “large bandwagon” of … Continue reading ?
Strings 2015 gets underway in Bangalore tomorrow, and so far the press coverage I’ve seen consists just of two articles that aren’t what I’d guess string theorists would like to see: In The theory that may have been stringing scientists … Continue reading ?
One of the many efforts to promote the Multiverse to the public way back when (2005-2007, some of their advertisements are here) was an organization called Multiversal Journeys. Back in 2006 they got $77,000 in funding from the Templeton Foundation … Continue reading ?
Ordered from the more to less serious… On the geometric Langlands front, there’s video posted today of this talk by Dennis Gaitsgory. Michael Harris has already commented here about the local geometric Langlands conjecture in terms of 2-categories that Gaitsgory … Continue reading ?
Last week Princeton hosted what seems to have been a fascinating conference, celebrating the 50th anniversary of studies of the CMB. Hopefully videos and slides will be posted, but one can get some idea of the highlights of the talks … Continue reading ?
Every so often I’ve ended up taking a look at something about theoretical physics on Reddit, generally ending up not spending much time there. One reason was that I realize I’m already spending more of my life than is healthy … Continue reading ?
The New York Times had an op-ed piece this weekend by Adam Frank and Marcelo Gleiser, entitled A Crisis at the Edge of Physics. They make some of the usual criticisms of string theory and the multiverse, ending with Are … Continue reading ?
I’m trying to get back to blogging about quantum mechanics slogans, this one is about relativistic quantum mechanics. I’m hoping it will stir up more trouble than my last East vs. West one. If you’re doing calculations in relativistic quantum … Continue reading ?
Run 2 of the LHC is about to start with first stable beams scheduled for Wednesday morning, Geneva time). If you’re up (I’ll be asleep) you can watch a live webcast, or watch what is going on here. The current … Continue reading ?
Since the news of the tragic death recently of John Nash and his wife in an automobile accident last weekend, some of those who were at Princeton during the same time I was (late 70s, early 80s) have been exchanging … Continue readi...
I’m busy with other things, so no possible way I can keep up with the claims about string theory flooding the media for some reason these days. It’s hard enough to find the time to read all of this, much … Continue reading ?
I was sorry to hear this morning that John Nash and his wife Alicia died yesterday in a car crash (news story here). They were in a taxi on the New Jersey Turnpike, heading home from the airport after a … Continue reading ?
First test collisions at 6.5 TeV/beam at the LHC are tentatively scheduled for Thursday morning. At CERN today there’s a workshop about the Higgs Machine Learning Challenge. Also on the topic of LHC data analysis news, Tommaso Dorigo announces the … Continue reading ?
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 ?
