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 →

USC Science Film Competition – A New Year!

…And here we are again! I’m launching the second year of the USC Science Film Competition as of, well, a few seconds ago. Please go to the website to learn more. You’ll find a collection of links at the very end of the main page, along with a slide show, talking a bit about last year’s successful inaugural competition. I’m hoping for a competition at least as exciting and interesting (er, in all the good ways!) as last year.

If at USC, spread the word, please! I especially need faculty to help encourage […] 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 →

Well, Can the Physicists?

Back in Los Angeles, where I can start the process of working colour under the inks and building the images into the pages where they belong. Here’s a panel from mid-conversation.

I’ve been quiet here for the last five days for a variety of reasons. One of them is that I got a bit of a nice routine on some work going (finally), and so wanted to milk that… and another is that I got a bit ill, and needed time to recover.

I’ve lots to tell, but might not get to much of it due to getting on with doing several things. There’s one interesting series of events (amusing mishap, […] Click to continue reading this post →

New Inks

Part of the process of redoing some of the work I did in the prototype story for The Project. This is an inked treatment of one of a trio of panels in the story entitled “The Arena”. (Warning: Some of the cross hatching has become a little muddied in this reproduction, and the paper has come out somewhat dark. This is because I took a snap with my camera… A proper scanner will resolve all that when I get back to my office.)

While redrawing, I noticed that one of the things that was unsatisfactory about the old version is that the entire light model was wrong. The bright window in the setting, from where the natural light comes, is to her left, not her right. I must have changed the characters’ relative sitting positions at some point in the story but forgot to adjust the light… I’ve noticed it on more than a couple of pages…

It might not seem like much, but you the reader are more aware of […] Click to continue reading this post →

Technology, Teaching, and the Difference

There’s a nice piece* over in the Chronicle of Higher Education entitled “Don’t Confuse Technology With College Teaching”, by Pamela Hieronymi. I like it because it expresses nicely some of the thoughts I try to inject into the discussion when people begin to go all gaga over technological supplements in teaching, going too far and thinking that somehow it can be used to replace classroom teaching.

Hieronymi talks about the online lectures that are being rolled out with great fanfare in recent times by some of the famous institutions. (Online lectures have been out there for a while, but have been making the news more now that the big names have been doing it…of course.) The issue of the use of technology in the classroom itself (clickers and so forth) is not discussed in her piece, and rightly so… I think there are more nuanced discussions to be had there, and it should not be confused with the matter of online lectures.

Overall, I think that the online lectures are really excellent services that different people can use in a variety of ways, and it is great to have them out there. But […] Click to continue reading this post →

The Future of Physics

On Saturday we had another series of celebration events for the 50th Anniversary of the Aspen Center for Physics. It began at 2:00pm with a discussion in Paepke auditorium entitled “The Future of Physics”, and it was introduced by Michael Turner, and moderated by Lisa Randall, with three Nobel Prize winners forming the panel: David Gross, Bob Laughlin, and Adam Riess. (I decided to do a short sketch during some of it, and then quickly splashed on some colour later in the evening*. The result is above. The sketches are meant to give a sense of the stage and people on it, not be representative likenesses, so I refer you to pictures of them for actual portraits…)

There was an excellent turnout, and audience members were treated to a good and wide-ranging discussion. It was a difficult subject to grapple with, and Lisa started out in a good place, by getting each panelist to take turns to describe their way into physics, then around again to talk about the areas they got their Nobel Prizes in. She supplemented their contributions with some of her reflections on her own experiences and points of view, and tried to unpack some of the concepts brought up here and there when she thought it might help the audience.

From there, things became a bit tricky, since there were several directions in which to go and it was not clear what the best structure to follow was, given the time allotted and that they needed to stop and get members of the audience involved. Like I said, it was a difficult assignment for all of them. What emerged was a loosely structured series of interesting reflections from each of them at various points, some healthy disagreements there and here (I think it was good for the public to see that we’re not all cut of the same cloth) – for example between David and Lisa on the meaning of […] Click to continue reading this post →

In Defense of Teaching Algebra

Over at HuffPo, my colleague Nick Warner has posted a piece about why we teach algebra to people who supposedly “won’t need it”, and he makes some excellent points. (Recall the silly New York Times piece by Andrew Hacker entitled “Is Algebra Necessary?” that I mentioned a few posts ago.)

I recommend Nick’s piece.

I did not make it to the annual “Strings xxxx” conference this year (where xxxx = current year), but I heard that it was good. It was held in Munich. See the lovely poster on the right. (I wonder who did the splendid painting?)

The organizers did a great job of rapidly updating the website with slides and video of the talks so that a wider audience can benefit from them. The video page is […] Click to continue reading this post →

On Screen!

Comments Off on On Screen!

I had a pleasant surprise yesterday. I went along to the public lecture of Ralph Cicerone, the president of the National Academy of Science, since on the one hand his talk was entitled “Contemporary Climate Change as Seen Through Data”, so it was interesting to me, and on the other hand I was to be part of a group taking him to dinner later on. I went into the auditorium and lo and behold there was Rosie Wyse (Aspen Center for Physics President) up on the screen…! They were showing the film (what film? see e.g. here, here, and here) in the time leading up to the start of the lecture, as people were arriving. It was nice to see it up on a large screen being enjoyed by an audience…

Overall, the reports back are that everyone seems to love it, and that it has been […] Click to continue reading this post →

Becoming Engaged…

It turns out that a really great way of passing the time when listening to someone give a talk is to do some sketch practice. [… wait, what? The post title? Oh! No, no, don’t be silly. Ok., let me continue …] If the subject matter is right, it’s a good thing to do while you focus on what’s being said. This last couple of days I’ve been in Aspen, Colorado, and I’m starting out my visit here with a three day conference entitled “Becoming Engaged: Initiatives That Can Change Science Education”. You can see more about it on a dedicated website hosted by ICAM. One of the people behind it is David Pines, and we’ve had many conversations about science outreach and science education over the years, and so he invited me to participate. I’m supposed to be here at Aspen for my visit to the Aspen Center for Physics, and so I’m only partially attending, opting to to listen to some talks, and take part in some discussions… then going back over to the center to hear some LHC and Higgs chatter on the LHC workshop that is starting up this week.

There are a lot of interesting people talking about science education, and science outreach, many describing their various approaches and projects in short talks and presentations. (I will tell you about some of them in future posts.) It is great to meet several people who are passionate about outreach too, and see what others are up to and share ideas… so this is a valuable time. Hopefully, some action ideas will come of this meeting that […] Click to continue reading this post →

Working Group

It wasn’t all lecture halls, discussion rooms, and cafeterias for the workshop. The organizers arranged for a boat tour last week, and we all sat on one of those splendid long, wide and low tour boats that you often see on the canals in Amsterdam. It was nicely equipped with a bottle of wine at each table, and the crew members handed us each a glass of sparkling wine as we embarked. Very nice. There was a lot of fun chatter from each table for the whole trip around the canals (so much so that they stopped the attempts to inform us over the PA system about some of the sights we were seeing, since the sound was drowned out by the conversations), covering (from what I could hear) a wide range of topics from well beyond physics to matters concerning topics presented in the workshop.

Sometimes pads of paper and pens appeared. Above is a group (David Tong, […] Click to continue reading this post →

The Bridge

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 →
