Travels

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 →

Somewhere in there, somehow, I am keeping my head above water…just. But then I decide on something equivalent to tying extra weight to my ankles. Last week, while deciding on what I would talk about in the short time I have, I decided to do the whole TEDYouth talk graphic novel style of course… Which means hundreds of drawings… Why do I do this to myself? (I can recycle some of this for The Project, I suppose…) So I sat in the sun on Saturday afternoon […] Click to continue reading this post →

TEDYouth Approaching!

Ack! As you know, it has been an incredibly busy semester for me, but I still try to find time to tell you a bit of what is going on. Not long ago I got an email from the TED people asking me if I’d like to talk at one of their events. This event is for young people, called TEDYouth. It’ll be on November 17th. Well, this is such a good cause – how can I not do this?

TEDYouth speakers photoYou can see the announcement of the “incredible lineup” of speakers on TED’s site here. (I linked the photomontage they used there.) I’m looking forward to being in the audience to hear some of these guys talk!

So of course, I now find myself a week behind where I should be in terms of preparation, and in the middle of a whole bunch of other deadines… […] Click to continue reading this post →

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 →

Incomplete…

But I sort of like them like that. It is a busy time, but I thought I needed to do something different and so last night I popped into a studio I visit to do a “drop in and draw” session. I’ve told you about these before. There were not too many other sketchers there, which is nice, and it was also nice to have a model that was not the usual (often tedious to draw) thin sort, but who had lots of interesting forms that played well with the light. This makes drawing interesting. (Click for larger view.)

I was rusty, not having done this in a bit, but rusty in an interesting way – I was seeing forms and getting balance fairly well (with some obvious proportion issues […] Click to continue reading this post →

Playing with Planets

Somewhere in all the craziness (that has partly been responsible for the light posting of late), yesterday I had time to rush over to a lab to do some demonstrations for a new TV show that is upcoming. It went rather well, since some time was found to prepare all the logistics for it, and one of our lab demo experts, Angella, did a great job of sourcing the things needed and testing it out beforehand. My job (after helping with the logistics of getting the operation off the ground and connecting some of the dots to make the shoot happen) was to show up and talk about the science and do the demonstrations.

It was about conditions on some of our popular neighbouring planets, and so in addition to holding models of the dear things and talking a bit about them to camera, I engaged in some demonstrations. The demos were simple enough – showing how to boil water at room temperature by simply dropping the pressure, and showing how sulphuric acid wreaks havoc with sugar by sucking the water out of it, making an impressive black column of carbon… fun!

I was glad to be doing some science discussion for public consumption again as we did not shoot any new episodes for The Universe this Summer (as in previous years)… They are still working through the backlog of shows we shot from last year, apparently. Part of the recent craziness was dashing off to another part of town last week to shoot some segments for another show entirely (some online material for a […] Click to continue reading this post →

New Experiments

For a while I’ve been wondering about watercolour pencils. It seems like a great way of carrying around some strong colour that can be applied in a simple way and not too messily while out and about.

You’ve seen me quickly splash colour onto a line sketch digitally, by scanning (on on the road, photographing) the result and pulling it into the iPad and using Brushes, (see e.g., here, and here) but that’s… something else.

Also, even at home/work, if I want to do a quick colour study before doing a whole page for The Project, it is nice to be able to play with colours I can apply in a more tactile way, and step back from the result and see how it looks. So, I got a set of watercolour pencils (made by Derwent) and a portable water-fillable brush (made by pentel) and grabbed a ball point pen and looked around for something to experiment with. I settled on an issue of Vogue Patterns Magazine (I get it for the craaaaazy weird poses of the models… well, really I get it for my sister) and did a quick series. Line drawings of a model, then apply pencils (mixing experimentally to get something that resembles skin tones from a set of pencils that don’t come close), then brush with water in various ways to get some rough colour, and highlights.

The results were fun! I made some mistakes at the start since I did not know just how […] Click to continue reading this post →

Flyover!

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 →

Edible Fractals, and the Snowflake

Comments Off on 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

Comments Off on 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 →

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 →
