Meanwhile, Somewhere Down South…

hotel_down_south_1st_Sept_2014So while at a hotel somewhere down South for a few days (pen and watercolour pencil sketch on the right), I finally found time to sit and read Graham Farmelo’s book “The Strangest Man”, a biography of Dirac. (It has a longer subtitle as well, but the book is way over in the next room far from my cosy spot…) You may know from reading here (or maybe even have guessed) that if I were to list a few of my favourite 20th century physicists, in terms of the work they did and their approach and temperament, Dirac would be a strong contender for being at the top of the list. I am not a fan of the loudmouth and limelight-seeking school of doing physics that seems all so popular, and I much prefer the approach of quietly chipping away at interesting (not always fashionable) problems to see what might turn up, guided by a mixture of physical intuition, aesthetics, and a bit of pattern-spotting. It works, as Dirac showed time and again.

I’ve read a lot about Dirac over the years, and was, especially in view of the title of the book, a little wary of reading the book when I got it four years ago, as I am not a fan of going for the “weren’t they weird?” approach to biographies of scientists since they serve too […] Click to continue reading this post →

And Back…

subway_sketches_27_08_2014It is a new semester, and a new academic year. So this means getting back into the routine of lots of various aspects of the standard professor gig. For me this also involves being back in LA and taking the subway, and so this means getting (when it is not too busy as it seems to get a lot now) to sketch people. The guy with the red sunglasses was on his way to USC as well, and while he was reading or playing a game on his phone (such things are a blessing to sketchers… they help people hold in a fixed position for good stretches of time) I was able to get a quick sketch done in a few stops on the Expo line before we all got off. The other guy with the oddly trimmed beard was just briefly seen on the Red line, and so I did not get to make much of him…

I’m teaching electromagnetism at graduate level again this semester, and so it ought to be fun, given that it is such a fun topic. I hope that the group of […] Click to continue reading this post →

crochet_forest_7Given that you read here at this blog, you may well like to keep your boundaries between art and science nicely blurred, in which case you might like to learn more about the coral reef forests made of crochet spearheaded by Margaret and Christine Wertheim. The pieces mix crochet (a hand-craft I know and love well from my childhood – I got to explore my love for symmetry, patterns, and problem-solving by making doilies) with mathematics – hyperbolic geometry in particular – as well as biology (mimicking and celebrating the forms of corals – and drawing attention to their destruction in the wild). You can read much more about the projects here. I’ve mentioned the work here before on the blog, but the other day I went along to see a new set […] Click to continue reading this post →

photo_laser_mirage_shoot_small involving a laser and liquid nitrogen (so, around -320 F, if you must use those units), to this in the kitchen:

west_maroon_valley_sketch_10_aug_2014I promised two things in a previous post. One was the incomplete sketch I did of Crater lake and West Maroon Valley (not far from Aspen) that I started before the downpour began, last weekend. It is on the left (click to enlarge.) The other is a collection of the wild flowers and other pretty things that I picked for you (non-destructively) from my little hike in the West Maroon valley. There’s Columbine, Indian Paintbrush, and so forth, along with […] Click to continue reading this post →

Outstanding in Their Fields…

In case you missed it, Maryam Mirzakhani has been awarded the Fields Medal! This is regarded as the most prestigious prize in mathematics. Here’s a Guardian article covering it at a general level, and here is the page on all the award winners, with more detail on each, at the International Mathematical Union website. The reason this is a big deal (and why it is newsworthy) is because it is the first time the prize has been awarded to a woman. In a world where, despite the number of excellent women mathematicians out there, there is still a perception problem in the general populace about who (or more to the point, what gender) is associated with achievement in mathematics, it is important to note and celebrate such landmarks.

I also note that one of the other 2014 awardees, Artur Avila, is from Brazil! While not covered as much in the press as far as I can see, this is another big […] Click to continue reading this post →

Mountain Sketch

I went for a little hike on Sunday. Usually when I’m here visiting at the Aspen Center for Physics I go on several hikes, but this year it looks like I will only do one, and a moderate one at that. I had a bit of a foot injury several weeks ago, so don’t want to put too much stress on it for a while. If you’ve looked at the Aspen Center film (now viewable on YouTube!) you’ll know from some of the interviews that this is a big component of many physicist’s lives while at the Center. I find that it is nice to get my work to a point where I can step back from a calculation and think a bit more broadly about the physics for a while. A hike is great for that, and in all likelihood one comes back from the hike with new ideas and insights (as happened for me on this hike – more later)… maybe even an idea for a new calculation.

maroon_bells_sketch_10_aug_2014

So I took the bus up to the Maroon Bells and hiked up to Crater Lake and a bit beyond into the West Maroon Valley, hunting a few wildflowers. I will share some pictures of those later. (I’ve heard that they are great up at Buckskin pass, and I was tempted to push on up to there, but I resisted the temptation.) I brought along several pens, watercolour pencils, and a water brush (for the watercolour pencils) because I’d decided that I would do some sketches at various points… you know, really sit with the landscape and drink it in – in that […] Click to continue reading this post →

Perseids, Meet Supermoon!

So tonight (meaning the wee hours of Monday morning and the next few mornings, for optimum viewing – more civilised hours might work too, of course) the Perseid meteor shower will be on view! Have a look at this site (picked at random; there are many more) for more about how to view the meteors, in case you’re not sure. Well, here’s an interesting thing. The moon will be at its brightest as well, so that’ll mean that the viewing conditions for meteors will not be ideal, unfortunately. And it really will be extra bright (well, slightly, to be honest) because tonight’s full moon is during the moon’s closest approach to […] Click to continue reading this post →

Aspen Art Museum Opening

aspen_Art_museum_new_building_7_aug_2014_04

I just got back from the Aspen Art Museum‘s new building. They’ve been having a members-only series of nights before the big opening to the public in a few days, and an invitation was sent along to Aspen Center for Physics people to come along, and so (of course) I did. It was a nice thing to do at the end of a day of working on revising drafts of two papers, before settling down to a nice dinner of squash, green beans, tomatoes, and lemon-pepper pasta that I made, all from the Saturday Farmers’ Market. But I digress.

Let me say right at the outset that the building is fantastic. There will no doubt be arguments back and forth about the suitability of the building for the town, and so forth (and there have been), but as a space for both art and community (and to my mind, those should go together in a city’s main art space) it is simply […] Click to continue reading this post →

subway_sketch_5th_august_2014_smallBack in Aspen. I went back to LA for a long weekend, and my travel back to Aspen today gave me a lot of good thinking time. Also, I got a few very quick drawings done, such as the one on the right of a cooperative fellow (looking at his phone) on the subway on my way to Union station to take the LAX Flyaway bus.

I’ve been thinking about two projects, one physics and the other about physics, going back and forth between the one and the other, trying to not let them interfere with each other. The “about physics” one is of course the graphic physics book project. In itself it is in two parts. I’m adding more pages from time to time – drawing, inking, and painting/colouring when I can – and I’m also having the odd conversation with potential publishers from time to time, and sending off proposal packages to appropriate places that accept them… trying to explain the nature of the project to those who are willing to listen to something new and exciting. As I’ve said before, “new and exciting” are not words that most publishers want to […] Click to continue reading this post →

Café Talk

cafe_sketch_27_06_14 Here’s a quick sketch I did while in Princeton last month, at a new café, Café Vienna. (See earlier posts here and here for sketches in an older Princeton Café. I’m using a thicker marker for this one, by contrast, giving a different feel altogether, more akin to this one.) This new café promises to recreate the atmosphere of the Cafés of Vienna and so I kind of had to have coffee there before I left. Why?

Well, two reasons, one obvious and the other less so: […] Click to continue reading this post →

Triply Dyonic

dyon_phase_diagramsI thought I’d mentioned this already, but I could not find anything after a search on the blog so somehow I think I must have forgotten to. It is a cute thing about a certain favourite solution (or class of solutions) of Einstein’s equations that I’ve talked about here before. I’m talking about the Taub-NUT solution (and its cousin, Taub-Bolt). Taub-NUT is sort of interesting for lots of reasons. Many, in fact. One of them concerns it having both mass [tex]M[/tex] and another parameter called “nut charge”, [tex]N[/tex]. There are several ways to think about what nut charge is, but one curious way is that is is sort of a “magnetic” counterpart to the ordinary mass, which can be thought of as an “electric” quantity.

The language is based on analogy with electromagnetism, where, in the usual […] Click to continue reading this post →

Hey, You…

page_extract_27_07_2014_2Today (Sunday) I devoted my work time to finishing an intensely complicated page. It is the main “establishing shot” type page for a story set in a Natural History Museum.

This is another “don’t do” if you want to save yourself time, since such a location results in lots of drawings of bones and stuffed animals and people looking at bones and stuffed animals. (The other big location “don’t do” from an earlier post was cityscapes with lots of flashy buildings with endless windows to draw. 🙂 )

Perhaps annoyingly, I won’t show you the page_extract_27_07_2014_1 huge panels filled with such things, and instead show you a small corner panel of the type that people might not look at much (because there are no speech bubbles and so forth). This is seconds before our characters meet. A fun science-filled conversation will follow…(Yes these are the same characters from another story I’ve shown you extracts from.)

Pot Luck

pot_luck_25_04_14_6Here in Aspen there was a pleasant party over at the apartment of one of the visiting physicists this evening. I know it seems odd, but it has been a while since I’ve been at a party with a lot of physicists (I’m not counting the official dinners at the Strings conference a fews weeks back), and I enjoyed it. I heard a little about what some old friends were up to, and met some spouses and learned what they do, and so forth. For the first time, I think, I spoke at length to some curious physicists about the graphic book project, and the associated frustrating adventures in the publishing world (short version: most people love it, but they just don’t want to take a risk on an unusual project…), and they were excited about it, which was nice of them.

pot_luck_25_04_14_1It was a pot luck, and so although I was thinking I’d be tired and just take along a six-pack of beer, by lunchtime I decided that I’d make a little something and take it along. Then, as I tend to do, it became two little somethings…and I went and bought the ingredients at the supermarket nearby and worked down at the centre until later. Well, first I made a simple syrup from sugar and water and muddled and worried a lot of tarragon into it.

pot_luck_25_04_14_2 Then in the evening, there was a lot of peeling and chopping. This is usually one of my favourite things, but the knives in the apartment I am staying in are as blunt as sticks of warm butter, and so chopping was long and fretful. (And dangerous… don’t people realise that blunt knives are actually more dangerous than sharp ones?) […] Click to continue reading this post →

74 Questions

open_questions_cvjHello from the Aspen Center for Physics. One of the things I wanted to point out to you last month was the 74 questions that Andy Strominger put on the slides of his talk in the last session of the Strings 2014 conference (which, you may recall from earlier posts, I attended). This was one of the “Vision Talks” that ended the sessions, where a number of speakers gave some overview thoughts about work in the field at large.

Andy focused mostly on progress in quantum gravity matters in string theory, and was quite upbeat. He declines (wisely) to make predictions about where the field might be going, instead pointing out (not for the first time) that if you look at the things we’ve made progress on in the last N years, most (if not all) of those things would not have been on anyone’s list of predictions N years ago. (He gave a specific value for N, I just can’t recall what it is, but it does not matter.)

He sent an email to everyone who was either speaking, organising, moderating a session or similarly involved in the conference, asking them to send, off the […] Click to continue reading this post →
