Playing with Planets

By | | , , , , , ,

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 →

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…)

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 →

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 →

A Funny Thing Happened on the Way to the…

On Tuesday I headed to Santa Monica. Two dear friends of mine had invited me to a private screening of a film they’d just completed, one as writer+director, the other as producer. The film was a labour of love, and I’d not heard much about its progress since earlier in the year, and so I was delighted to be back in town to go to it. I took a friend along, and we decided to leave early enough to go to the beach for a little while – the traditional antidote to the high heat of the last several days.

To cut a long story medium, at some point I was wading up to my knees in the water. I’d just replied in reassurance that I’d be quite fine still wearing my glasses (with sunglasses attachments on) since I was not going to swim when a larger than average wave surged forward and knocked me off my feet with such stunning force that I thudded to the bottom on my knees, and my face and hands got tangled up in seaweed! Moments later, the undertow pulled everything back I and I was standing back up, fumbling with seaweed, and missing my glasses! This began a period of considerable activity at the sea, with large surges and strong pullback so that it was difficult to stand still to look for anything, and moreover, it was impossible to see anything since the sand was churning around too much.

It all seemed very funny to me. It was clear after a while that there’d be no reappearance of my glasses. No amazing story where the sea threw them back out after a while, twisted, maybe missing the arms, but at least useable for some kind of vision… There were simply no glasses to be had. Luckily, my friend had driven us, so I did not have to worry about that. There was little time to dash back home to get an old pair and return for the screening. I’d have to figure out how to manage without them. Now bear in mind that I am very short sighted indeed. If I was sitting five feet […] Click to continue reading this post →

Nostalgia for the Light

Have you heard about the film “Nostalgia for the Light“, by Patricio Guzmán? As you know, one of my main cares in the business of communicating science broadly is having it be mixed up nicely with the rest of the culture (not making it a lecture all the time). This helps reach broader audiences, for a start. In a sense, this looks like a film that is doing that. It seems it was released in 2010, but is appearing on some big screens for the first time this year, in some places. I’ve not seen it, but it is soemthing I intend to see, based on the synopsis alone. I thought I’d mention it to you.

The summary from the Guardian film site says “Drama in which a group of Chilean astronomers’ search for the origins of life is contrasted with local womens’ efforts to find the bodies of loved ones killed by the Pinochet regime.”

There’s a trailer here:[…] 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 →

Curious about Curiosity?

Comments Off on Curious about Curiosity?

So, if like many people, you are excited about the (late) weekend landing of Curiosity (the roving Mars Science Laboratory) on Mars, and/or if you want to know more, Kenneth Chang has an article in the New York Times all about it here. (Image right is an artist’s impression done for NASA/JPL.) The sequence of operations that have to go right for Curiosity to, er, stick the landing* is quite amazing, and so let’s all wish them good luck. Have a […] Click to continue reading this post →

New York Times Nonsense

By | | , , , ,

I can’t decide whether to be annoyed or amused by the opinion piece by Andrew Hacker entitled “Is Algebra Necessary?” in the New York Times on Sunday*. Annoyed because it is such an obviously flawed piece of writing, essentially saying that since (in the US) the system is failing to teach lots of people basic mathematics in school, the solution is to stop teaching it rather than figure out what is going wrong with the teaching process, while at the same time very lamely trying to make the case that it has no use anyway. Amused because it’s obviously flawed, and hopefully anyone reading it will laugh – one’s first thought has to be that it is not a serious article, given that it it is published in a respectable newspaper with reasonably educated editors.

But one can’t – shouldn’t – laugh, since there are (sadly) many people (lots of whom […] Click to continue reading this post →

Superconductivity for You!

By | | , ,
1 Comment

I was very impressed with the presentation Julien Bobroff gave in Monday’s public dialogue here at the Aspen Center for Physics. It was all about Superconductivity, and he and his team have done a tremendous job of putting together lots of materials for exploring this topic. Its a great example of some really careful thinking producing very accessible ways into understanding a remarkable quantum mechanical phenomenon that has quite a bit of striking and direct impact on a number of walks of life. This makes for great material for everyone, whether you are an expert physicist (who might want to show some of this to others), a teacher who wants some good materials to your classes, or simply someone who is not an expert but just find yourself curious about the world.

Have a look at their excellent website where everything is collected together, […] 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 →
