The showcase and awards ceremony for the Science Film Competition is tomorrow (Wednesday)! It’ll be in the film school, at the Stark Family Theater (SCA 108), at 7:00pm. I’ll be screening films that were entered into the competition, and then at the end of the evening, giving out large prizes! $3000 first prize, $2000 second, and $1000 third. Should be a fun evening, with refreshments after the ceremony!
Come along and bring friends. […] Click to continue reading this post
[Update: replaced sketch with the painted version.] I managed to get a sketch done of some of my colleagues present at the meeting I’m part of here in San Antonio, TX. They’re across from the table from me, and as far as I can tell, not aware that I’m sketching. Was a fun experiment with quick layout. I’d have painted it, but I seem to have forgotten […] 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 was interviewed by an online publication called The Arts and Entertainment Magazine for their 1st January edition. You might find it interesting, since I talk about some of the themes I bring up here a lot, such as trying to improve public understanding of science, and various projects connected to that sort of thing. It is here. Enjoy!
Actually, they’ve started doing a series of spotlights on various scientists, so browse through the website for other interviews, if that interests you.
What? The final exam I set on Friday. I spent a lot of time trying to get this final exam right. The problem is that I tend to decide at some point that I want to set an “interesting” exam, and then this usually ends up being more work for me than for the students, since you not only have to think of the questions and make them the right level of difficulty (made harder by being open book and, in this case, a take home -well, take to where ever for 4 hours), but then endlessly debug to see that it has no mistakes (since I won’t be present to answer questions). This time, I spent a lot of time on units, since I wanted to set an exam that kept all the factors of c and mu and epsilon present in all the relativistic notation and right down to the final unpacked Maxwell equations and all the quantities they computed in various examples. I decided to have them explore a little non-linear electrodynamics, since everything they’d seen was mostly linear. You start with the familiar (Maxwell) form of the equations:
Well, Thursday’s meeting was a blast! I had decided not to try to get people to RSVP for the meeting this time, and so when it came down to the day before, I had no idea how many were going to show up. This meant that I had to make some guesses about how much coffee and tea and cookies to organize, which was a little bit of a challenge. But just before 9:00am people began to show up, and kept showing up, and by time I was ready to start off the day’s meeting, there was a really good crowd!
In the end it was a great day, with five really good talks and lots of excellent discussion. […] Click to continue reading this post
You might remember that during the Spring and early Summer I was deeply embroiled in making a film. (See several earlier posts, e.g. here, here, here, and here).) It was a short film to celebrate the 50 year anniversary of the Aspen Center for Physics, and I was keen (in my role as filmmaker) to give it a treatment that benefits from my being a theoretical physicist, and one who is familiar enough with the Center, all in order to get the right tone of the film. (Jump to the end of the post if you want to see it without more background thoughts.) There’s a spirit of the Center that is quiet, reflective, and inspiring of thoughts that need time to be explored, so I definitely did not want the usual loud, buzzing, overly busy type of film that you often see about science activity. It did not seem appropriate. Working with Dave Gaw (who was an awesome principal cinematographer and editor for the project) and with Bob Melisso (who shared some of the production and direction work with me), I think the result strikes the right note overall. A fun side note: I got to design a number of unique (and definitely handcrafted) elements for the look that I think you’ll like and recognize from other visual work of mine you’ve seen on this blog, and just as with my earlier film projects from 2009 (see here and here) it was a real buzz to help figure out how to make them fly, and then see the elements come together in their final form up on screen.
People really seemed to like the film a lot, from what I’ve heard. (It was shown extensively at many of the Summer events celebrating the 50th at the Center.) So while it did take a lot of my time, it seems like it was time well worth spending since […] Click to continue reading this post
The next Southern California Strings Seminar is on Thursday 13th December! I’ve now made the website for this one and it is here. Come back to it from time to time to see the updates of talk titles as speakers let me know what they are. It is a one-day event filled with five talks and plenty of time for discussion. I’ve snagged a lovely room in the Doheny library again. (Photo left has a shot of the room we used last time it was at USC in May 2011. The most recent one was over at UCLA.)
You are welcome to come and do physics with us! Also, if you’re part of a group in […] Click to continue reading this post
Sort of stuck this morning. I was up at 6:30am (more or less my usual time these days) with good intentions to get back to do a nice stretch of work on The Project for the first time in a while. But it is almost 10:30am and I’ve done nothing (not counting procrastinating, making fruit compote for pancake breakfast, sending a bunch of emails, and so forth).
It is difficult sometimes to reboot back onto task on a project when one is suddenly done with one of the major things pulling you away from it. Classes are over, you see, and so I am transitioning into a different mode, and not super-efficiently.
I think maybe before I have to leave to run errands out in the world (after lunch), I must get something done toward […] Click to continue reading this post
…Again. I’ll be on the road again this morning. Heading to California State University Long Beach. They invited me to give a colloquium a while back and I agreed, and when I returned from New York last week I realized I needed to urgently spend a chunk of time thinking about what I was going to talk about, and designing a set of slides for it. The last couple of days saw me devoting a lot of time to it. Eventually I decided to dig back into ancient times (the 1990s) surveying some of the interesting things we’ve learned about strong coupling phenomena (involving unexpected reorganization of degrees of freedom and the number of spacetime dimensions at times), and then discuss what it all might be good for in view of work going on in the last decade or so.
Come to think of it just this moment, this is a chance to do a tribute to David Olive, who passed away earlier this month. (He was one of my professors when I was at Imperial College in the ’80s.) Ideas of strong/weak coupling dualities and their utility were given a huge boost by his work in this area from decades ago, perhaps the most famous being Montonen-Olive duality… I must remember to mention that in the talk. (See here for an archive of 2004 talks in celebration of his work. I borrowed the image to the right from there. I do not know who took it.)

Here’s the first slide of my TEDYouth talk from Saturday. It was time consuming but fun to draw all those hands and tiny items of various sorts. The whole talk was about what I call “hidden structures”, which in a sense is what my field (high energy physics, particle physics, cosmology, string theory, etc.,) is all about. To help motivate it all, I started by talking about opening up your smart phone and figuring out how it works by taking it apart and discovering the components inside, and using the rules of how to put them together to deduce the structure of other things (see that second stage of the slide being delivered on stage*).
Since I’m hugely into getting people to learn by really getting stuck into things […] 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
…Progress? I hope so. I lost about 7 hours yesterday. Hours that I’d planned for working on the slides for TEDYouth and (mostly) finishing them. There was a weird problem on the computer I use that seemed to seep into Illustrsator as well. Somehow dragging a file to copy or move it somewhere else would not work, and this meant that in Illustrator if you tried to drag an object to a new position, it would fail to complete the operation, generating a copy in the place you moved it to but not erasing the original… It would then freeze. I tested this out in so many different ways to see that it was not damaged objects or files… then eventually decided to reinstall the entire operating system (Lion). Of course, this is no […] Click to continue reading this post
