[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
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
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.
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
Penultimate lecture today in the graduate electromagnetism class. These last four lectures are a lightning tour through some important concepts – showing how many of the things we’ve been doing all semester fit with Special Relativity. (For example, amusingly, showing that the Lorenz gauge condition is in fact Lorentz invariant…) It is fun to show a powerful example of how an important guiding principle (such as writing equations in a Lorentz-covariant way) can end up making several features of the theory seem much more natural, while also leading to new physics. This is fun to do, although it does mean that I end up writing whole new notes for this since I am not a fan of the way some of these electromagnetism books (Jackson included) decide to treat time in an odd way, such as treating it as imaginary (which must be so confusing to some students) just so as to write Lorentz transformations like a rotation, or using mostly negative signatures for spacetime, and so forth. And, inexplicably, using different units of measurement from the choices made in the rest of the book… Anyway, so the last two lecture-writing sessions have mostly been one of fiddling with minus signs and factors of c, 4 Pi, minus one, and so forth. Joy. Well, the group seems excited since they’re beginning to see things that they’d seen in other classes and it is all making some sort of sense now (Klein-Gordon equation, duality, etc., etc…) I think the last class will show how many of these things flow from variational principles. Maybe I’ll find a little time to do the Born-Infeld model? I’m excited too, although I’ll be sad to end the class and stop working with this fun group of students.
Today I managed to grab a few sketches on the train. This afternoon coming home on the Expo line these two snoozing gentlemen were kind enough to sit still for a few minutes each for me to get down a few impressions of their features. This was all helped a bit by the train sitting still for a while as we waited for a truck to get off the line. Apparently it was parked or stuck there.
Perhaps not helpful was this young guy who watched me drawing and then decided […] Click to continue reading this post
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
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
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

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
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.

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
As you know from reading here, I think that careful thought is important. I like it in conversation, among other places, so I like it when people take the time to stop and think about something before talking.
I prefer conversations with such space over those interactions where everyone is trying to somehow “win” it by filling all available space with chatter, contentful or not. (In fact, over the years, I think I’ve gone out of my way to avoid the latter as much as possible, including the people who tend to need to engage that way…) So not surprisingly, when writing conversations, for example for The Project, you’ll find that I have places where time […] Click to continue reading this post
