Just Great!

quantum_criticalI’ve no idea why I’m writing a blog post about this, since I can’t really explain any of the details in a way that won’t sound tediously technical. I’m just pleased since I had a sort of perfect workshop moment for a couple of hours after the weekly picnic at the Center today. I’d been talking a bit last week with Lincoln Carr, an excellent condensed matter theorist at the Colorado School of Mines, and had also been talking with Allan Adams, another excellent physicist, from MIT. Allan and I seem to be on the same page as theorists and so I really enjoy talking with him. We work on string theory, but are not fussy about where the physics that it can be applied to might come from. As long as it is good physics. We both seem to love the idea that there’s so much rich physics, that might be accessible with string theory,[…] Click to continue reading this post →

Haunting while Working

Well, there are two Aspen cafes that are probably a bit sick of me. The last couple of days saw me frequenting one or other of them while I worked on a number of things, primarily finishing writing a paper. I’ve focused on little else but finishing it up so that I can get on with other things, such as my various other projects, and also to allow me to pay attention to the interesting talks coming up in the workshop […] Click to continue reading this post →

Uses For Strings?

viscosity_scatterThere were a couple of string theory stories in New Scientist last week. I forgot to mention them earlier. One is entitled “What string theory is really good for”, by Jessica Griggs. The other is entitled “Why cats fail to grasp string theory”, by Ewen Callaway.

Well, since cats are involved, of course I’m going to start with an extract from the second (even though it is obvious that the cats are deliberately skewing the results):

[…] Osthaus’s team attached fish or biscuit treats to one end of a string. A plastic screen with a small gap at the bottom separated cats from their reward, requiring the felines to tug on the string to get the treat.

With a single string attached to the food, most cats learned to paw at the string to get a snack. But when Osthaus’ team introduced a second piece of string, […]

Well, that was to pique your interest. You’ll have to go off to the source article to get to grips of this second piece of stringy research. The first article? It’s a discussion of […] Click to continue reading this post →

An Odd Time

watchWell, it was an unusual day here in Aspen. It was a day with lots of talks. Six of them, I think. There were four workshop talks scheduled for the morning, each of half an hour I think. Also got into a discussion before the sessions began, helping to explain how gauge/gravity duals work to a condensed matter colleague. I checked a voicemail message (only a relatively limited set of people have my number and so I figured it was a call to which I’d want to respond) and, despite the fact that I’m in retreat mode and would normally ignore it, returned the call. It was an office at USC wanting to put me in touch with a journalist who needed help. From Esquire. No, it is not what you think. I suggested they can could call me at 13:05, and at 10:30 went to the talks.

Somehow, successive speakers kept running over time due to lots of (actually, pretty interesting) interruptions and discussions, so I did not mind that we got to 12:50, and my talk, which was scheduled for 12:00-12:30, had not happened yet. With […] Click to continue reading this post →

Ink Time…

ink_break_aspenAh, time to relax a bit after a somewhat busy last couple of days glued to the notebook and computer. The results? (1) A hasty colloquium to an audience of mixed expertise to try to get across a sense of why some of us are excited about various applications of string theory to a diverse range of physics including ongoing experiments in nuclear physics and condensed matter physics (the person who was going to do it was a bit ill apparently so I stepped in with some hastily prepared slides… a bit messy but hopefully some use)… (2) Two papers with my student Tameem on applications of string theory techniques to superconductivity (one will appear on the ArXiv in about 20 minutes if you are interested [update: it is here.])… (3) Notes for a talk I’ll give on Thursday about said new results… (4) Several discussions with and ideas sent to some documentary film makers about some new TV shows coming up – Season 4 of The Universe! Seems I’ll get involved in some of them (stay tuned)…

So this morning I went to sit and cool down a bit at a cafe I like to visit a lot when in Aspen. Ink Coffee. Ok, I see that I did not yet mention I was in Aspen. Have been for […] Click to continue reading this post →

Categorically Not! – Awesome

Comments Off on Categorically Not! – Awesome

cat_not_optical_puzzleThe next Categorically Not! is this coming Sunday May 29th. The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events. (Image above right is from the excellent Categorically Not! – Really? event back in April 2006, described in an earlier post here. It was all about illusion, with examples from the world of optical illusions, and from literature.)

The theme this month is Awesome. Here’s the description from K C Cole:

lhc_and_mont_blancJester at Resonaances reports on a talk by Jörg Wenninger about the progress at the Large Hadron Collider (LHC).

There’s information about the repairs, more thoughts about the accident last year, and somewhat frightening news about issues of quality control on some of the manufacturing of crucial parts that may haunt the entire project for some time to come. […] Click to continue reading this post →

Go! Now! Get a Galileoscope!

I just learned from Phil’s blog that the Galileoscopes I mentioned to you some months back (remember? International Year of Astronomy? Not just Darwin year?) are ready for shipping. There were issues with production at first, but now they are ready. The key issue right now seems to be that they are in danger of having to stop production of these lovely things if they don’t get lots of orders by May 31st. Ack!

So please please consider sending in a order for one or a few. Imagine what a delightfully unusual gift it would make for someone. Either someone you know, or someone you don’t know like a neighbour, your local school, church (yes!) or community center, or… even that special someone who you’d like to get to know – what an icebreaker, eh? Here’s a picture from the site of what a happy owner’ll have after assembling it:

It is easy to put together, gives a new window onto the world above your head, and […] Click to continue reading this post →

Remind Me Not To Do This Again…

film_notesI’ve just finished two days of staring for long stretches at the computer screen, reviewing all my footage for the films, (see also here) making careful notes about which takes I like, which I don’t, which are salvageable, which are a total mess, suggestions for cut away shots, transitions, other edits, etc, etc, etc… These notes are for my film editor, who will now take the hard drive of all the footage to begin cutting the first rough versions of the films.

It was a time-consuming process, with the additional complication from the fact that the Industry is in some disarray when it comes to high definition (HD) formats. Largely due to the explosion of technology, the move to, and the demand for the format from the consumer TV world, there is no universal standard for how different camera manufacturers (and even the different models of a given manufacturer) save the files they make, and for how to get those files safely and reliably off the camera and on to your computer in a way that allows you to view them.

Fair Play

Yesterday saw my annual stint of judging at the California State Science Fair. Somehow it managed to sneak up on me this year, and so I did not get to do what I planned to do, which is encourage one or two scientist/engineer friends of mine in the area to sign up to get involved, since it is such fun and quite rewarding (ahem: Michelle P., Amy M., mark your calendars for next year! I’m going to come a-calling…) See earlier posts (e.g., here, here) for science fair descriptions, and the fair’s own site with lots of photos each year is here.

(Ok, there’s the whole getting up in time to arrive there by 7:00am or so. That bit is less than good, perhaps.) I arrived a bit later than 7:00, due to some breakfast procrastination that science_center_parkingI somehow sometimes manage to do even when I wake up with plenty of time (a whole hour this time) to get ready. My plan to simply set out by 6:10am and pleasantly walk/bike and bus down (my usual mode) was thwarted by this and so I had to take a somewhat quicker mode of transport, launching out of the batcave in a hurry at 6:50am! By 7:15am the parents and students in their SUVs and minivans were arriving at the California Science Center in droves, and so this meant that parking was a bit more of a challenge that it would have been 15 minutes earlier. But as you can perhaps see on the right (click for larger view), it all worked out in the end… ( 🙂 )

Here’s a shot of the annual morning briefing of the volunteer judges (all well fed, […] Click to continue reading this post →
