It turns out* that the local NBC affiliate did a piece on the California State Science Fair (which I reported on yesterday). There’s a brief overview, shots of some of the students talking at their displays during the judging, and interviews with some of the students. It’s rather good. Link to it here (unfortunately you have to let it play a brief ad first).

Yesterday was a full day indeed. The main event? The California State Science Fair. The venue? The California Science Center (just across the road from USC). Here’s a picture of it in case you’ve never been:

The time? 7:00am. Yes, we start early, as there is a lot to do for the long morning. The judges all gather in the IMAX theatre for a briefing about the ins and outs of the organization this year, the times at which various things will happen, and a reminder about some of the finer points of judging.
At 8:00am we broke up into groups of judges who will judge various sections. Mine was Applied Mechanics and Structures – Senior. Here, we decided on our collective strategy concerning how we’ll go around the various displays, making sure at least five judges (there were ten of us in total) see each project once in the first round of interviews. We’ll compare notes during the break at 11:00am, agree which ones we should all have seen – in order to focus on deciding which ones get which prizes or honourable mentions. I forgot to take a picture of our group of judges sitting around the table chatting. Most of the judges in my group were people from the aerospace industry, I gathered. About three or four people were new to the whole thing, and so some of us explained a bit about the things that we ought to be looking out for in the judging. This also (given the section were were to judge, and given the makeup of the judging panel – many coming from an industry where the place where the science and engineering are quite thoroughly – and necessarily – mixed together) leads to discussion about making sure to distinguish between a great science project and a great engineering project. It’s also good to be aware, when making comparisons, of the vast differences in resources that some entrants have access to. These two things, to my mind, are very important (and we all agreed). A kid (especially one with access to lots of resources, for example) can dazzle an unwary judge with lots of fancy cool equipment and build something that is truly wonderful and admirable, but that does not necessarily mean that they would have done as much science as the next entrant who has done some very careful scientific experimentation with a innovative way of answering a clearly stated question, but in a less spectacular setting – perhaps mostly using more affordable household items.

Well, with that in mind, we all went off to meet the youngsters! See the project listings here. This is the best part, of course… talking with all those enthusiastic young people Click to continue reading this post
(Random title constructed to reply to Bee’s post called Asymptotic Backreaction.)
You know, I’ve made some great online friends here on this blog. It’s all the result of that community I’m trying to keep going (and expand) here with contributions to the conversation from many of you in the comments, and even sometimes in guest posts. I’ve been lucky enough to meet some of these new friends since everyone likes to pass through Los Angeles sooner or later. In the past six months, four familiar Asymptotia contributors have passed through Los Angeles and I’ve been lucky and delighted to meet them: – Amara (November; on her way to a conference, and she gave us a talk – I’m trying to get her to do a guest post on her “Watering the Earth” topic one day), Candace (January; on her way to a conference here -she did a guest post) by the way, Athena (two weeks ago, on the way to a conference), and this week I finally met Bee (also giving a talk, and on her travels -she’s also done a guest post by the way) who turns out to have just that same excellent eye for observation, and quietly sharp sense of humour, as her blog posts. (She’s the main blogger behind the excellent Backreaction, and she’s done a post there which briefly mentions her visit to Disney Concert Hall with me.)
Anyway, in the photo below is Bee (click for larger), at Grand Central Market (inserted into a photo taken near one you saw earlier. See also this post.):

If you’re looking for a day (or half day) out today in the greater Los Angeles area, let me suggest a trip up to the Jet Propulsion Laboratories (JPL). (Details here.) Their open house (held today and yesterday) is rather fun…. you get to learn about some of the grand space missions of yesteryear (like the 1977 Voyager missions… both craft are still actively sending data from beyond the solar system now), or of the moment (like Cassini-Huygens, for example sending wonderful pictures of Saturn and Titan back for us to learn from and marvel at – see e.g. here), or to come soon (like WISE (an infra-red telescope which will help broaden and deepen our understanding of planetary systems, galaxies, and the universe at large), or Dawn (a mission to go and orbit and study two large asteroids).
You can learn lots of things about the science these missions are teaching us about not only far away worlds, but about our own world. There are also missions which are studying earth directly (making observations about our atmosphere, oceans, and so forth), so even if you don’t care about space, there’s something for you.
You can visit special exhibits for each of the missions, talk to scientists and engineers, and even visit the large warehouses where the spacecraft are made, and where they are assembled. There are the control rooms to visit, 
a dome with giant robots (I’ve no idea about that one), an extra special exhibit about Mars exploration, and lots of stations with all sorts of entertainment for kids! They’ve done a great job providing a lot of material for everyone to take away, including packets of information for teachers to use in their classes too!
The Jet Propulsion Laboratory will have on open house today and tomorrow! This sounds like a lot of fun, actually. More about it on their website, from which I snatched:
This popular event will celebrate JPL’s accomplishments with exhibits and demonstrations about the Laboratory’s ongoing research and space exploration. Many of the Lab’s scientists and engineers will be on hand to answer questions about how spacecraft are sent to other planets, how scientists utilize space technologies to explore Earth and how researchers are now searching for planets beyond the solar system. Visitors will see exhibits, displays, demonstrations and presentations about new technologies, solar system exploration, spacecraft communication and much more.
The Open House is a fun and educational experience for children too, with special hands-on activities designed for kids. Food and beverages will be available, along with space souvenirs and NASA and JPL merchandise.
I think I’m going to go along and have a look! Maybe I’ll see you there…

The Gravity Research Foundation announced its awards for the 2007 essay competition. (Hmm: I think we should have more technical science essays, in more categories, to inform each other about what the big questions and answers are…. and maybe even just for fun (because I’m in a silly mood) -and to make an important point about how vital it is to communicate what we’re up to to each other- have a swanky awards ceremony, with speeches, and music, and an MC, and everything. And of course it should be held somewhere in LA… Like the LA Times Book Awards. It could be held at the same time as (another fantasy): awards we give to our peers for the important task of writing essays, books and other efforts in the service of communicating science to the general public.)
But anyway, you can read all about the winners of this year’s awards here. Nicking a bit of text from the site, here are the top prizes:

Jean-Jacques Sempé does it again, with another great New Yorker cover. This time, his subject is- my people! (click for more detail):
Pretty interesting to see the choices of equations actually (mostly various quantum mechanics statements – Schrodinger’s equation, Heisenberg’s uncertainty principle, the definition of the Hamiltonian in question (there seems to be an external electromagnetic field?), then there’s a reminder of what happens in beta-decay of the neutron…and there’s the inevitable Einstein’s E=mc2 thrown in at random… and more…).
It’s great to see all this up there… although it is worth noting that a more typical blackboard would have (instead of definitions/statements known very well to the physicist) much more of a working computation in progress, probably.
Of course, if the physicist knew that he or she was to be on a New Yorker cover, perhaps they would have Click to continue reading this post
One of the Large Hadron Collider’s detectors, the Compact Muon Solenoid (CMS).
As you gather a lot when there are discussions on the topic here and elsewhere, there’s a lot of excitement and anticipation among high energy physicists about a number of things. I would go as far as to say that we are already in a very rich experimental time for results pertaining to high energy physics (or, if you insist, “fundamental physics” issues (I have in mind, for example, all the wonderful cosmological and astrophysical data that continues to come in, with more to come), and it is set to possibly get much richer – maybe even a new Golden Age with a little bit of luck – when the Large Hadron Collider starts producing results. We are really going into the (relative) unknown with this experiment, and this will be a great time to be working in the field – with a little luck, as I keep repeating.
A number of substantial articles have recently appeared in the general media that give you a good sense of what is going on, more reasons (and more detail) for why there is Click to continue reading this post
One of my colleagues here at USC, Itzhak Bars (picture right, by Don Milici), spends a lot of effort trying to understand aspects of time. In fact, in his way of approaching things, the fact that we see a single time dimension (all the others being space dimensions) would be a consequence of certain choices (“gauge choices”, in the more technical language) made, whereas in the underlying formulation, there’s be two times. Yes, two.
You hear about extra dimensions, and you think “string theory”, no doubt. No, this is nothing to do with string theory. He’s developed this idea independently of string theory for Click to continue reading this post
The History Channel is diversifying a bit, and doing their first science show. It will be called “The Universe” and will premiere on Tuesday, May 29, 2007 at 9pm ET. It will be a series of 13 episodes. Here’s a blurb I found on the web:
It’s been fifty years since man first ventured into outer space. Now we have robots on Mars, telescopes capturing the birth of the stars and their collapse into black holes, and probes slamming into comets at hyperspeed. What we’ve learned has completely changed our understanding of the universe and our relationship with it – we once thought ourselves to be at the center, now we know we are a small, small spec. This epic series throws light on all the known universe and out to the edge of the unknown – what’s going on out there, what is our place, and is there life outside of Earth?
I like the idea of more TV channels (besides the usual suspects like PBS or Discovery) getting involved in making shows that have more science, so given the end that it serves (see the about page) -and because it is interesting and fun work- I was happy to help out when I got a call to do some interviews to camera for use in the show. (The other show I did some segments for last year -see here and here– turns out to be part of a (reportedly somewhat saucy) variety and comedy show, I’ve since heard! It will air on another channel in the Fall, and I’ll tell you more about it then. )
We recorded on Thursday. The original plan was to record in a house in the Hollywood Hills, with access to some Griffith Park backdrop to shoot some b-roll of me doing a bit of hiking, but the fire put a stop to that. Instead, we found another location – a house with a lovely garden overlooking the Topanga wilderness. (Actually, they wondered whether we could use my house and garden, but I decided that the garden was not ready for prime time yet, having just begun to come out of its Winter slump where there was hardly any rainfall… So it remains still just between me and you my dear blog readers, ok? In the end, it would not have worked anyway since on Thursday there was still a lot of activity from helicopters en route to patrolling the Griffith park embers… not good for filming!)
How did it go? Ok, it started well. There were two separate settings, for two separate Click to continue reading this post
By the way, in case you’re in town here and looking for a good show, I ought to mention Assassins, put on by the Sight Unseen Theatre Group at the Meta Theatre. I saw it with a group of friends on Saturday night and it was excellent. (Friends mostly from a rowing club, go figure. Not a grouping I expected to meet in LA…No, I don’t row, I met them at a party the previous week.) A Stephen Sondheim musical (very clever songs and lyrics therefore), with excellent direction and performances, based on the book by John Weidman. They’re going to be done by the end of the week, so move fast.
The various assassins and would-be assassins of various US presidents, assembled together, with guns, song and (a bit of) dance.
So I don’t know whether you’ve noticed or not, but there’s been an awful lot of penguin movies (or movies with a big penguin component) recently. There’s yet another one to come out soon about surfing penguins. I’m slightly annoyed by it already, and I can’t really tell you why. It could turn out to be good, I suppose…
So I got to thinking that this could be theoretical physics’ big break! We can pitch our own penguin movie, since we have up our collective sleeve…
The penguin diagram!
This is a type of “Feynman diagram” describing how various particles interact with each other in a specific process. (More on Feynman diagrams here, for example.) What does it have to do with Penguins? Well, this picture I got from Wikipedia might help:
Apparently, John Ellis is responsible for their appearance in the literature, pushed along by Melissa Franklin. The usual suspects were involved too (drinks, a pub, darts, etc…) From the Wikipedia article here is the story, in (we’re told) John’s words:
It’s Mother’s Day in America… but it can be Mother’s Day everywhere!
(Rose from my garden earlier this week. Made a card out of it for my mum…)
Cliché, I know, but I presume that is what calling it “Commencement Day” is all about. Is that not right?
(Commencement Day at USC: Part of the crowd of graduates, family, and friends assembled in front of the grand stage set up in front of the Doheny library.)
Yesterday was both a happy and slightly sad day for me, because I’m a bit of a softy when it comes down to it. Quite a number of the students I taught over the last few years graduated yesterday. While I was so pleased to see them all happy and looking forward to moving on, and meet their parents and siblings, 
I was also a bit sad, since I won’t be seeing them around the USC campus any more. I feel like I’m losing a number of good friends, which seems like an odd thing to say given that I don’t really know them all as friends in the usual sense…. But I got accustomed to seeing them around, spending time with them talking, laughing, worrying, puzzling… getting coffee, milkshakes… They became a real part of my life for a while… Now they are off to take on the world. I feel a bit like a parent… perhaps I’m getting broody?
The campus was lovely yesterday, even more than it usually is. The ground staff Click to continue reading this post
