I’ve been looking at some of the many changes to Princeton, as I get the chance between sessions at the conference. A significant one for me is that Small World Coffee has really thrived and grown significantly. I can’t over emphasize how big a deal the place was to the lives of many in Princeton when it opened in 1993. Believe it or not, there was no real cafe in Princeton when I arrived the year before. The arrival of small world was a huge deal. It meant not just decent coffee, but a gathering place, a place to hang out, and a little art and performance space. Such places existed before, but on campus, and mostly for the benefit of the student population. I was not a student at Princeton, although many of my friends were, so although I went to such places as well it was nice to be in a cafe that was part of the actual community that was the town of Princeton. Several postdocs loved that the place opened, and we went there a lot. Perhaps it helped balance out the ratio of trips up to New York to choosing to stay in town… Ok, just a little bit, but a significant amount. I remember my friend (and fellow IAS postdoc and neighbour at the time), Marc Kamionkowski, playing his saxophone there (sometimes putting on his “Cat in the Hat” hat for a number – he may not forgive me for mentioning this), and I’d go along to support him.
I sat there yesterday and was pleased that the expanded seating at the back meant lots of nice vistas from which I could look at other patrons without being [...] Click to continue reading this post
It was the departmental retreat this weekend, and we all went off on a boat to an island! On the voyage back I decided to practice a little sketching, and found myself surrounded by good subjects, because a lot of people were sitting still during the crossing (it was a small boat). Since the boat was rocking [...] Click to continue reading this post
I’ve just returned from a rather wonderful two rainy days in Santa Barbara celebrating the work of Joe Polchinski. (See my previous post for more about this, including a few reflections.) It was a combination of high school reunion, group hug (with Joe in the center), and serious reflection about physics, now, back then, and to come. Now the great news is that pretty much everything was recorded on video, and so you can take part in it by settling down in front of your computer (or other device – those of you in the further (but pre-singularity) future can just instruct the appropriate plug-in from [
Cyberdine systems ] [ Tyrell Corporation] Google to stream directly to the vision centres of your brain) and view the various excellent talks and panel discussions here.
I had the honour of chairing (and contributing to) one of the panel discussions reflecting on D-branes (as I promised last post). The title was “D-Branes: Tools of the Revolution” and it went very well thanks to my three excellent panelists (Greg Moore, Andreas Karch and Samir Mathur) and many members of the gathered audience who contributed to the free-form discussion in the 15 minutes at the end. Have a look at that right along side the really interesting and lively discussion that Steve Shenker chaired at the end of the conference (which sadly I had to miss because I had to get back to LA through the rainstorm for another engagement). The idea there was to speculate a bit about the future of physics and thereby “Planning for Joe’s 90th Birthday“.

You know those cross-country trips that nip from one coast to another for a day and then back? There are people who do that regularly for a living. Honestly, I don’t know how they do it. I left LA on Monday to go to a meeting in DC, and returned on Tuesday night, and while nothing unpleasant happened en route (and the meeting at the DC office of the American Physical Society was good), it is really not something I’d make a habit of. I like to add a bit of time to see the place I’m visiting, and get a bit of a feel of the pulse before flying back. But there wasn’t time. I was in DC for a day and a half last November to visit another organization, and I did manage to get two hours to wander the mall and have sandwich in the cafe of the Smithsonian, but I’d have liked a bit more time back then too. Anyway…
I did, however, get some face time. On take off on the flight back I flipped through Hemispheres (United’s in flight magazine) to see if there were any more large faces to sketch. (You’ll recall several earlier posts about my liking to do this for practice [...] Click to continue reading this post
I find myself in a cold climate for a short while, once again serving on a committee that needs my in-person participation. It is snowing outside here in Chicago, and it is nice to look at the snow from the window, and occasionally pop from one building to another.
This allows me to pretend that as a Southern-California-softy I’ve had my annual dose of proper cold weather, with a real opportunity to wear a heavy coat and a thick jumper (sweater to those State-side) for at least one time this year. My hotel room is in a tower, and has a nice view out of the window. I tried to take a shot that captures the spirit of it. Pity I’m not able to enjoy it much, given [...] Click to continue reading this post
While I was apparently catching that horrible flu virus early last week during the travelling I was doing, I was killing time with a few sketching games I tend to do while travelling. I was grabbing faces. A moderately careful face grab is to look through whatever magazines I have to hand (such as the in-flight magazine) and see if there are interesting faces… then I might do a quick or longer drawing of one or two that I find. Sometimes they are familiar people, as is perhaps the case with the one I show to the left. This was not intended to be super-careful, and was rather quickly done, but it turned out to be nicer than I expected.
I was simply drawing with a pen and not trying to be very accurate, and just capture expression and structure of the face, but my eye was in and so… (I’d have used pencil if I was planning to go for accuracy…) I liked it enough to finish it up when I got home and throw some watercolour (pencils and then water brush) on to it. (I took a quick snap of the magazine photo before I left to allow me to recall some features for finishing.)
I’ll spare you the other ones I did in that mode. Not for public consumption! [...] Click to continue reading this post
So that was by far the most ill I’ve been in many years. The flu wore on for five days, with two and a half of them having me mostly in delirium, fighting highs and lows of fevers… quite remarkable. Then I had two extra days of eating very little, so that by time I started eating real food again on Saturday, and going outside, it was as though the world had been made anew to see and taste various things I’d not had in a while…
Ok… I suppose this means maybe next flu season I’ll finally start taking flu shots? We’ll see.
Anyway, I am reasonably sure that I caught that virus while passing through Atlanta airport on my way back from New Orleans. There, so many paths cross as it is a major hub. Spending two hours there gave me ample time to pick something up. Then there’s the plane as well, with four hours to sit in one space in contact with the things a possibly infected traveller before me had contact with. Nice.
I’ve been much better for a few days now, and semester has got going here. I’ve given [...] Click to continue reading this post
I’m in New Orleans for a few days. Exciting, as I’ve never been here before, but it has been on my list of cities to visit for a long time…
I thought I’d share with you the above photo of an important (to me) artifact that I visited in the old US Mint building, which has a number of exhibits. This is the cornet that, as a boy, Louis Armstrong leaned to play trumpet on!
This is sort of a big deal for me. It would be like finding a set of notebooks that the young[...] Click to continue reading this post
After arriving back home from New York on Sunday night (late) my next tasks were to sleep and wake up super-early to write some lecture notes on various approaches to treating diffraction (vectorized Kirchhoff integrals and so forth) for my class, and to grade several weeks of homework assignments…. all before the day’s guest (Howie Haber from UC Santa Cruz) arrived to visit and give us a departmental colloquium entitled “The Higgs Boson Unleashed”. It was great, and included discussion of new results from the LHC announced just last week. Then there was dinner in one of the excellent new downtown restaurants where I seem to have become a regular (nice to be remembered by the wait staff sometimes).
Today I must think about what I’m going to say in a colloquium I must give at Cal State Long Beach on Monday… But before then I think I need to have a slow day as I’ve really not stopped being in extreme headlong motion on various projects and deadlines for over three weeks now.
Of course, I do try to create moments of quiet whenever I can. It is important to me. Sketching practice helps. I’d taken my watercolour pencils and little portable fillable [...] Click to continue reading this post
Well, it is great to be back in New York. Multiple times this year – hurrah! I’ve just got back from the Times Center where all the speakers have been running through their talks to smooth out kinks of various kinds (technical glitches, run time, etc). The senior TED people are here sitting in the auditorium and one by one we come up and go through things to give us a chance to get familiar with the stage, and to hear any thoughts or comments. (See tiny picture on the left.) People have done really good jobs preparing, and so most comments are simply ones of congratulations, with some small suggestions here and there with regards points of confusion, or sound levels, or run time. We’ve got six minutes. You heard me right – I must explain all of particle physics and research in string theory in six minutes. I like my challenges… Well, I spent a lot of time designing the content of the talk [...] Click to continue reading this post
I find myself on the East Coast for the first of two trips over here in two weeks. Next week I return to be in New York for the TEDYouth event (which I am still making slides for when I find some time here and there between the tasks I’m doing for this trip). This week’s trip means I’m missing two of my electromagnetism graduate classes, which I feel bad about because it is such an enjoyable group to teach*.
I must say that it is nice to get to wear serious outerwear for the first time in a while. I know – this is a particularly unoriginal thing you hear from a lot of us softies from the SouthWestern part of the US, and I apologize for saying it, but it is true! It is sometimes sad to see a nice heavy coat sit unused in a closet for a year or more, and there’s also a nice grounded feeling [...] Click to continue reading this post

In Rotterdam a couple of weekends ago, the North Sea Jazz Festival took place. It was an excellent event. Well, I think it was, based on my Saturday trip there with some friends – I assume that the other two days were at least as good. We were there from the start at about 4:00pm until about 11:30pm, when we went back (via trains, with an adventure story for another day) to Amsterdam. Seven and a half hours is a good amount of time for some excellent music to be heard and seen…
Turns out that there was great news for me right from the get go on this event. One of my favourite saxophonists from the younger generation playing out there these days, Joshua Redman, was the artist in residence for the event this year, and he did two concerts that day, in different configurations. (I say younger… I’ve been following his work for 20 years, since I first arrived in the USA all the way back (Princeton), shortly after his second album appeared. He was one of the hot new musicians on the scene at the time… But that was 20 years ago, so I suppose it’s time to use a different term…?)
I’ve seen him play a number of times over the years, on both coasts, in tiny clubs and in larger concert halls, and he’s always been great. This time he was probably the best I’ve ever seen him, and that’s saying something, since he’s usual so very good, along with the musicians he has in his bands. This time he’s part of a newer band called “James [...] Click to continue reading this post
One of my favourite scenes from the vast world of film is the one in the Shining where Wendy Torrance (Shelley Duvall) discovers that all her husband Jack Torrance (Jack Nicholson) had been writing on the typewriter for so long (when he was supposed to be working on his book) was “All work and no play makes Jack a dull boy”, again and again and again. There’s something utterly chilling about this, as the tension in the film has been building steadily, and the discovery reveals another seemingly solid foundation crumbling away…
The Eye film museum in Amsterdam is fantastic. For a start, it is in a wonderful building (see right -click for larger view) that you get to by taking one of the small ferry boats across from the Central Station, a fun journey. Right now they are having [...] Click to continue reading this post
The workshop has been fantastic, overall. In between discussions, the talks, and some thinking about my own projects, I’ve had some time to wander a bit, and look around. Yesterday after lunch I wandered a bit and then found myself settling down and doing a sketch of a bridge at a junction with lots to see. The Amstel is joined by Prinsengracht canal here, and it was fun to sit a while and put down some pencil lines, followed by firmer ink lines. I pulled the result into the iPad and splashed on some colour for good measure.
Having finished the paper last week, it has been fun to field questions about it from various people, as well as think at a more leisurely pace about the next [...] Click to continue reading this post
Well, the workshop is going well. I had to miss a talk this morning in order to carry on with this writing of a paper I was doing. Basically, we’re over due in producing our submission to a special volume of some publication or other that is going to be all about magnetic fields and models of strongly coupled matter… As you may have gathered by now, I’ve dabbled in magnetic fields for some several years by now, so it was natural to be asked. My collaborator in a lot of these dabblings, Tameem Albash, and a student, Scott MacDonald, and I have been working on a suitable project for a while, and due to my travels and entanglements with a previous project, I’ve made us all a bit late.
The last few days have been difficult for writing. I’d forgotten [...] Click to continue reading this post
Amsterdam! I’m here for a workshop for a while. It is on string theory – many aspects – and so the mix of people is a good one overall, with conversations ranging from high energy physics, the LHC (including the Higgs announcement at CERN expected tomorrow) and black holes all the way over to condensed matter and various kinds of exotic physics one can do in the laboratory in that context. It should be an excellent time here… It is good to be back in the city after over a decade, and to catch up with a number of friends and colleagues in the field. I also want to properly explore the city this time, not having done that much exploration last time. (Photo above is a snap taken of the lovely moon that came out last night, with the Amstel and accompanying reflections and so forth… Was pretty to see.)

I got a little sketch practice here and there where I could during the trip. On the return journey for example, I found a nice opportunity as we were preparing to land after the short flight from Aspen to Denver.
Bob Melisso, my co-Producer/Director was reading a magazine, and so was still for long(ish) moments at a time – enough for me to do a quick sketch of him in profile. It was reasonably successful. It was his birthday recently, so this made a sort of present. He seemed to like it…

The Expo line will be opening (after an incredibly long testing phase) on April 28th. I’ll be there, Brompton in hand, to test it out, I think. A couple of articles on it appeared in the LA Weekly and the LA Times.
I’ve been excited about this for a while, not just because there’ll be a station across the street from my office, essentially (and the fact that when phase two is completed in 2015, or thereabouts, I’ll be able to step out of my office and board a train for the beach), but because I [...] Click to continue reading this post
This is a snap of a sketch I started while sitting in the Village Vanguard (New York) the other night while listening to the Mark Turner (ts) quartet play. On trumpet was Avishai Cohen, who was really excellent. This quick sketch, very incomplete, was assembled from several glimpses of him when he’d return to this pose, or more or less… Anyway, it was a fun exercise (I’d started another larger sketch of the whole band, but decided it went off balance after a while and so did not complete it).

On my last day at the KITP in Santa Barbara (this visit) last week I decided, for old times’ sake, to go for a walk along the beach, to the pier, while reading two papers I wanted to think about. It seemed preferable to sitting inside at my desk, and it was a lovely day. I took my notebook/sketchbook just in case I wanted to make notes or sketch something interesting. It also seemed important to go along that beach at a proper slow pace since I’ve not been along there for many years, and it holds a lot of memories for me. (It is, for example, the beach I used to visit late at night – through midnight and beyond – regularly, to teach myself to play the trumpet… part of a story I may have shared with you once before.)
Anyway, while wandering along, and just before the pier, I noticed a group of people all sitting together out on the sand. I looked up from my papers to see what they were up to and realized that they were doing exactly what I thought I might do – they [...] Click to continue reading this post

Not long ago I was in Leadville, a mining town you get to from Aspen by going over Independence pass and then down into the valley. (It is apparently North America’s highest -in elevation- incorporated town, being at over 10K feet… Its roots are in gold and silver mining, starting back in the mid 19th Century.) I love visiting the big store that sells all sorts of curiosities and antiques there, and then after wading through lots of bits and pieces, going to the saloon bar for Irish coffees.
This time I actually bought something. Two things in fact – Some old handbooks for mine crew personnel of the Climax Molybdenum Company, from 1978. They are quite small, about 5 by 4 inches, but they are packed with delightfully presented dos and don’ts about how to do the job, including safety practices, and warnings about what might go wrong if you do things the wrong way. I particularly love the fact that the pages are [...] Click to continue reading this post
After just having walked down a few minutes from Electric Pass Peak back towards the Pass (the peak is a fun 13635 ft / 4156 m elevation), I remembered to take this short panorama to show the surroundings.

Toward the end of the week I gave in. Howie Haber had been regularly going on these long rides and suggesting that I come along. The one I would have done for sure, I said (truthfully) was the one with the tasty reward at the end – to Pine Creek Cookhouse – but the one that had been planned was two days after I arrived, and I did not think it was a good idea for me to do it without having acclimatized to the altitude. You may recall that a few years ago I did do that 12 mile route on a ride led by Howie, and it was fantastic. See the post here. So he asked me a couple more times to join a few riding up to Maroon Lake, which he was doing every other day, remarkably. It was a similar distance (well, a bit shorter – 10 miles) with perhaps a more steady, relentless climb to make up the 1500 ft altitude gain. But I did not get my mind into gear on the whole idea for some time (maybe especially since there was no tasty meal as a reward at the top). Then on Wednesday I gave in and stopped by Howie’s office and said I’d join him on Friday.
So Friday morning we set off, joined by a few others (including Josh Frieman), for a lovely ride. Pretty quickly we separated out into our various paces and pointed ourselves up the valley (I warned my co-riders at the beginning not to wait for me as I have a slower pace on the Brompton – the beauty in the photo on the right). I eventually got into a good rhythm and made steady progress. While I was not as strong as I was in 2008 (or perhaps not as well-motivated?), I still enjoyed it, although there were times when I did ask myself out loud “why am I doing this?!”, but that was usually after the dashing of false hope when I thought I was almost there only to round a corner and see the road stretching [...] Click to continue reading this post

(Scroll to the end of this post for the funny thing I actually intended to post without my own musings getting in the way…) It has certainly been a huge story, with national and maybe even international attention been given to it. Carmageddon is the name given to the event of the 405 highway being closed for a 10 mile stretch for most of this weekend, for maintenance purposes. People are warning of disaster, complaining, predicting calamities for business, stocking up on food supplies, and so on and so forth. Some people are angry, some are amused, some are confused. For the most part however, people are quietly making sensible plans to adjust their routines or plans to take account of the event. (Er, I’m not sure I’d include flying from Burbank to Long Beach among the sensible plans!*)
I’m sort of struck by the huge impact this is having in people’s minds, and it has raised all sorts of discussions, reflections, and arguments about the reliance on cars that people have, public transport, and so on and so forth. All subjects you’ve maybe read being discussed here over the years. (Search the archives and/or use the search bar to the right.) The clichés about there being “no public transport” in LA is a convenient one for all to use at times (or all the time) when we want to stay in our nice cosy cars and ignore the alternatives and the possibility of making adjustments to include even occasional use of them, but I readily admit that the West side is a lot closer to the standard image of Los Angeles in this regard than points further East (still staying decidedly North-leaning in the discussion of course – the South LA conversation is an interesting one for another time). The density of shops, cafes, and long, desirably walkable stretches with other pedestrians (yes, they do exist in LA) does indeed seem lower over there, and while there is some bus coverage, the lower density makes the flaws of that part of the transport system hurt more, and of course the subway/metro [...] Click to continue reading this post
I’m lounging around. In Cincinnatti Ohio. Why? Well, it has been a long day, and I’m tired. I spent the whole day yesterday traveling to get here, changing planed in Chicago, eventually getting to my hotel at 10:00 pm, having arisen at 6:00am. I spent the flying time thinking about physics and writing the talk I was invited to give here as part of the regional SPOCK meeting at the University of Cincinnatti. The letters stand for something, but I can’t recall what it is right now. It does not mean, as the title might suggest, that several emotionally-challenged and otherwise tv-cliche-handicapped individuals were meeting to discuss arcane matters in a room somewhere. It was a meeting of several people from the region’s string theory community to discuss…. Ok, ok, Ok…stop giggling!
I got up at 7:00am -really 4:00am my time- transferred all my pages of notes to the iPad, and got ready, leaving to do the short (I assumed) walk to the physics department in the wind and rain. I enjoyed that bit… I had however mis-estimated how long it would take me to get to the Physics department building, largely due to [...] Click to continue reading this post
