Southern California Strings Seminar

Southern California String Seminar May 2011 in progressThe 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

Talking

…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 title and abstract: […] Click to continue reading this post

100 Registered!

So one of the things that has been taking up my time is the USC Science Film Competition. Well, last week, an important (slightly nail-biting) deadline passed, and that was the date by which interdisciplinary teams should have formed (finding each other due to the awareness campaign I’ve been running around doing since August – with the help of faculty who kindly spread the word in their classes, the blog I set up, an article by Pam Johnson in the Dornsife News, and ads in the Daily Trojan), come up with a film idea, and registered it.

So the day came, and (of course) within 20 minutes of the appointed cut-off hour […] Click to continue reading this post

CicLAVia October 2012

Well, it was a lot of fun, once again. There was a huge turn out, and pretty much perfect weather for it (not the extreme heat of a week or two ago, for example). I was not part of a group this time, and so I was able to explore with a fair amount of random abandon this time, starting at MacArthur Park metro stop, heading downtown and then all the way to Exposition Park, where I stopped at USC to print something out at my office (a long report I need to read), then head back up to downtown, through the City Hall (and new Grand Park) area into Chinatown. That got me thinking about baked buns, and so having returned back past City Hall, stopping briefly at Grand Park to look at one of the many places where there were concerts, I made my way to Little Tokyo to this place I like to find red bean buns and had one during a short stop in a square.

It was nice to sit and listen to all the conversations, and look at all the people (in family groups, friend groups, solo, etc) enjoying the city. Just as I was leaving to head to the East LA leg a fellow came over with his two sons (on a bike with a tralier for one of them, if I recall) and asked if I was a scientist. I wondered for a moment what […] Click to continue reading this post

Flyover!

[caption id="attachment_12548" align="aligncenter" width="499"] Space Shuttle Endeavour and escort, flying over the California Science Center, its new home where it will soon be on display.[/caption]
Wow, that was amazing. So a group of us (Aimee, Amy, Tameem, and myself) decided to go down to the Rose Garden, across the street from the USC campus and in the grounds of the Califorina Science Center where the Shuttle will be housed. Of all the places in LA where there will be a flyover, surely we ought to get a good view from there. Also, the Rose Garden gives access to a large piece of sky, so even if it does not come super-close, we ought to get a good chance… That was the thinking. (A major landmark here was that this is the most USC people I’ve ever seen in the lovely Rose Garden – not counting people on their way to a game at the Coliseum…)

[caption id="attachment_12549" align="alignleft" width="300"] Shuttle Endeavour and escort, with the Natural History Museum just in view below. It is approaching the California Science Center.[/caption]Well, it worked far better than we imagined. The shuttle eventually appeared from the West, and people began to cheer and wave, and snap pictures and so forth… We all felt very lucky that they did that pass…. you could see the fighter plane (?) escort, and there it was appropriately (sort of) over the buildings where it will live out its days… We’d talked about what it meant to see the very last transport flight of a shuttle, the end of the shuttle program, the future of manned spaceflight, and so forth. We, and the […] Click to continue reading this post

Endeavour to Look Up!

The Space Shuttle Endeavour will fly (or will be flown by its carrier plane) over Los Angeles this morning, paying special attention to various LA landmarks. Don’t forget to look up! I’ve heard it will be around 10:30am, but double check since I might have heard that time incorrectly. I plan to start looking out by 10:00am, down on the USC campus, since the California Science Center (across the street) where the Shuttle will be housed, is one of the places it will specially fly over… More here.

Enjoy!

Edible Fractals, and the Snowflake

In celebration and anticipation of the unveiling of the Mosely Snowflake Sponge fractal on the USC campus later today, I’m reposting an old post about an edible fractal that I did back in February 2008. They say they will be serving fractal-themed food in the reception, and so I wonder if this is one of the foods that might feature? Don’t forget to come to the event! Recall that I (jokingly) speculated that when this fractal is completed the universe will end, as its purpose will have been served? Well, it seems that this has not come to pass, so… whew.

For other fractal-related posts, click here. You might also enjoy the lovely fractal-related film, Yaddda Yadda Yada, that won a prize in the competition last year.

Imagine my delight when I spotted this lovely piece of edible mathematics in the Hollywood Farmer’s Market this morning. The stall has several of them of many sizes (this was a very little one) and of several colours. Wonderful. If you don’t know what I mean when I talk about the mathematics, or use the term fractal, look it up. There are several things of note, among which are the wonderful spiral structures that you can see (Fibonacci spirals) all over, and which in various ways, encode the infinite sequence of numbers 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233…. (you get the next one by adding the previous two) called the Fibonacci sequence. Ratios of successive members of the sequence, (e.g., 5/8, 8/13, 144/233, etc) approximate what I’ve already mentioned in an earlier post is definitely my favourite number (if I […] Click to continue reading this post

While Appearing

Well, yesterday evening turned out to be very interesting. I went to two things, my main mission being to get the chance to stand up in front of the groups of students and tell them about the USC Science Film Competition. The first was at the Academy for Polymathic Study (what better set of students to interest in this than the ones signed up to do things in the spirit of polymathy?), during the late afternoon “Polymathic Pizza” series. (I’ve presented in that very series myself, talking about the idea of “Play” in science and how important it is for creativity and discovery.) Happily, my friend and colleague Tara McPherson from the School of Cinematic Arts was presenting, and so after I told the students about the competition, I sat and listened to her presentation, since I had some time before the next thing. It was marvellous, and the students were very engaged. Tara took them through the arc of her academic interests over the years of her career, showing how she morphed from (mostly) traditional humanist to someone who researches and explores the role of all kinds of media in popular culture, helping to explore and create new forms of journal, new ways of presenting data, and studying the impact of media. I recommend looking at the journal Vectors for an example of a journal that is designed to present works that would not work as well in traditional print (e.g., being able to have a scholarly discussion of a piece of video media is helped a lot by being able to show it alongside your argument – not so easy in a print journal), and then head over to Scalar, created by the Alliance for Networking Visual Culture (which Tara directs) which is collaborating with a number of University presses on various approaches to new platforms for new media in academia. She also mentioned various examples in the scientific side of things with regards using distributed media for things like crowdsourcing important data.

I had to leave before she finished, so did not get to ask her the question on many of your minds: what is the origin of the (playful?) choice of names Vectors and Scalar?

Then I went over the School of Cinematic Arts to meet another friend and Colleague, […] Click to continue reading this post

Along the Way

It has been a busy semester so far, but not a bad one at all. There are some exciting things I ought to update you on, but now is not the time as I need a different frame of mind to pull my thoughts together on those topics. We’ve got through Green functions in the graduate electromagnetism class, which meant that we’ve been playing with the retarded potentials and doing one or two fun things with them by way of examples. The group of students I have in class is really fun to work with, and they seem to like the class worksheets that I bring them to try out from time to time. They allow me to get the students into the habit of working on a specific example where they can see how to set up a coordinate system, interpret the general expressions we’ve derived in the context of a specific example, and solve it through to the end, interpreting their results, etc. It eats up a chunk of the (1 hour 50 minute) class time, but it is well worth it, since I think that they potentially learn a great deal […] Click to continue reading this post

New Things…

This week sees the beginning of the new semester here at USC. I’ve been easing into my new class, which is a graduate level electromagnetism course. It is fun material to teach, and so I expect to enjoy it. I taught it back in 2009, and you can find some posts I did on some of the material if you dig into the archives.

It is going to be a hugely busy semester, and in fact has started out that way already. I’m on far too many committees, boards, and working groups, both within the university and beyond, and have been invited to be on a number more that I’m thinking about, some of which probably I should say yes to. This is all in […] Click to continue reading this post

Slow Writing

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

Bringing Science to Schools

Here’s a nice article (by Ambrosia Brody) about some of the work the Joint Educational Project (JEP), Women in Science and Engineering (WiSE) and the Dornsife College of Letters, Arts, and Sciences (all here at USC) have been doing to get school students excited about science. It looks like a fun and valuable program, and it is always great to see the look of wonder on the faces of the students as they explore (see film below). (Photo is by Nick Pittarides for USC News.)

A nice aspect of it that caught my eye is that one of the films that got made for the […] Click to continue reading this post

Now Arriving…!


The new line rocks! I went down there with my Brompton on the earlier side of things, this morning. I took the Red Line and changed seamlessly to the Expo Line at Metro/7th, and it was an excellent ride. I really do think (as I said in the previous post) that this is part of a major transformation for the city. This is a transformation with regards things like energy usage, congestion, community, air quality and all those wonderful things public transport helps with.

Of course, at the outset there is something truly right, to my mind, about being able to easily connect from downtown to Exposition Park and the Science and Natural History Museums, the African American Museum, and of course USC – All major Los Angeles institutions clustered together and now connected back to the newly beating heart of it all. From USC, I can now easily connect to the music center, LA Live, MOCA, any number of my favourite restaurants, bars, cafes, and other places I love downtown, and then float on home on the Red Line, or off to Pasadena or Boyle Heights on the Gold Line. This is so exciting to see come to pass. I’ve been dreaming of trains running along Exposition Boulevard between USC and the Museums and the Rose Garden for many years now, and it is now a reality. Stepping off the train today at the Expo Park/USC stop was just magical.

I recorded some footage of my travels on it today for you and edited it all together into a ten minute film. You can see it in the embed below. Consider it an invitation to […] Click to continue reading this post
