The September issue of Astronomy magazine is now out, with a cover story on Multiverses: Science or Science Fiction? The author Bob Berman does a good job of explaining both the arguments for various Multiverses, as well as the reasons … Continue reading ?
With the kids shipped off to NSA summer camp, now is the time for mathematicians and physicists to head off to their own summer camp experiences. Some of these have websites where the rest of us can participate a bit … Continue reading ?
Symmetry, the FNAL/SLAC run online magazine funded by the DOE, today is running a piece of multiverse mania entitled Is this the only universe?. It’s a rather standard example of the pseudo-scientific hype that has flooded the popular scientific media … Continue reading ?
Frank Wilczek’s new book, A Beautiful Question, is now out and if you’re at all interested in issues about beauty and the deep structure of reality, you should find a copy and spend some time with it. As he explains … Continue readi...
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 ?
