STEM Keynote

keynote_at_stem_divide_cvjAs I mentioned, a couple of Saturdays ago I gave the keynote address at a one-day conference designed to introduce STEM Careers to underrepresented students from various neighboring schools. The event* was co-sponsored by the Level Playing Field Institute, but sadly the details of it seem to have vanished from their site now that the event has passed, which is unfortunate. It was good to see a room full of enthusiastic students wanting to learn more about such careers (STEM = Science, Technology, Engineering and Mathematics) and I tried to give some thoughts about some of the reasons that there’s such poor representation by people of color (the group I was asked to focus on, although I mentioned that many of my remarks also extended to women to some extent) in such fields, and what can be done about it. Much of my focus, as you can guess from the issues I bring up here from time to time, was on battling the Culture: The perception people have of who “belongs” and who does not, and how that perception makes people act, consciously or otherwise, the images we as a society present and perpetuate in our media and in our conversations and conventions throughout everyday life, and so on. I used my own experience as an example at various points, which may or may not have been helpful – I don’t know.

My experience, in part and in brief, is this: I went a long way into being excited […] Click to continue reading this post

Baby Mothra!!!

So I discovered a terrifying (but also kind of fascinating and beautiful at the same time) new element to the garden this morning. We’re having a heat wave here, and so this morning before leaving for work I thought I’d give the tomato plants a spot of moisture. I passed one of the tomato clusters and noticed that one of the (still green) tomatoes had a large bite taken out of it. I assumed it was an experimental bite from a squirrel (my nemesis – or one of them), and muttered dark things under my breath and then prepared to move away the strange coiled leaf that seemed to be on top of it. Then I noticed.

It wasn’t a leaf.

It was a HUGE caterpillar! Enormous! Giant and green with spots and even a red horn at one end! There’s a moment when you’re unexpectedly close to a creature like that where your skin crawls for a bit. Well, mine did for a while […] Click to continue reading this post

Screen Junkies Chat: Guardians of the Galaxy

Screen Shot 2014-09-11 at 3.13.03 PMYou may recall that back in June I had a chat with Hal Rudnick over at Screen Junkies about science and time travel in various movies (including the recent “X-Men: Days of Future Past”). It was a lot of fun, and people seemed to like it a lot. Well, some good news: On Tuesday we recorded (along with my Biophysicist colleague Moh El-Naggar) another chat for Screen Junkies, this time talking a bit about the fun movie “Guardians of the Galaxy”! Again, a lot of fun was had… I wish you could hear all of the science (and more) that we went into, but rest assured that they* did a great job of capturing some of it in this eight-minute episode. Have a look. (Embed below the more-click):

But How…?

I get questions from time to time about where the drawings on the site come from, or how they are done. notebook_and_tools The drawing I had in one of last week’s posts is a good example of one that can raise questions, partly because you don’t get a sense of scale after I’ve done a scan and cropped off the notebook edges and so forth. Also, people are not expecting much in the way of colour from drawing on location. Anyway, the answer is, yes I drew it, and yes it was drawn on location. I was just sitting on a balcony, chose which part of the view I wanted to represent on the page, and went for it. I wanted to spread across two pages of my notebook and make something of a tall sketch. See above right (click for larger view.) A quick light pencil rough helped me place things, and then a black […] Click to continue reading this post

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

Coral Forest

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

Making and Baking….

Back in LA, I had an amusing day the other day going from this* in the TV studio…
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:
tasty_things_1 involving butter, flour, water and shortening… (and once in the oven, around +350 F) which ultimately resulted in this: […] Click to continue reading this post

West Maroon Valley Wild Flowers

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
