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.

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
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! […] Click to continue reading this post
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.

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: […] Click to continue reading this post
Jean-Jacques Sempé does it again, with another great New Yorker cover. This time, his subject is- my people! (click for more detail):

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 years, working first with quantum mechanics, and […] 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
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:

The next Categorically Not! is Sunday 13th May – Mother’s Day! (USA). The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See the links below for some recent descriptions (and even video) of previous events.
The theme this month is recycling. Here’s the description from the site:
Everything gets recycled: newspapers and banana peels, the air you breathe and the earth you walk on; some would even say our souls. Our bodies, we know, are made from materials recycled in generations of stars. The mix of genes that makes us who we are is a stew recycled by long lines ancestors—something nice to remember on Mother’s Day. Artists recycle everything from concrete objects to abstract ideas. New musical forms—like new scientific theories—are inevitably reconstructed from pieces of the past.
We’ll start with the ancestors of us all: the stars. An astrophysicist with the Carnegie Observatories, Alan Dressler uses both the Hubble Space Telescope […] Click to continue reading this post
Science and Society… Science Education. You’ve heard me speak of this issue so many times here, so I won’t repeat myself too much. Seems that Natalie Angier is in agreement – So much so that she took matters into her capable hands and wrote a book to try to change things: “Canon: A Whirligig Tour of the Beautiful Basics of Scienceâ€. I have not read it, but I’ve heard a lovely NPR interview with her today, and she read an extract. You can hear it at this NPR site, and also read an even longer extract there.
In the interview, she backed off a bit from saying that everyone learning a bit of basic science literacy is of vital importance (increasingly so in this day and age, I’d say), although she acknowledges that there are a number of us in the scientific community who do think so. You’ll notice the -perhaps understandably- lighter approach (â€these things are fun…†) that is taken in the book blurb I quote below. While I agree that the fun part is very important indeed (and we really need to get that across a lot!), and that one should always try to persuade rather than scare, I do think that we’re in a dangerous situation sometimes with regards the overall science education and attitude to science of our citizenry. We should definitely not be reluctant to say it. I think that she thinks so too, but does not – when promoting a book – want to make the book seem like it is bitter medicine, but rather, a bit of tasty candy. I’d prefer to think of books like this as a delicious piece of fruit: both tasty and good for you. To be fair, I should mention that in the interview, while declining to subscribe entirely to the view herself, she mentioned a scientist acquaintance who considers the issue as analogous to the urgency for everyone to acquire literacy when the world changed and printing and the written word became common currency. While we are not quite there yet, I’m inclined to agree with that view, on balance…
Well, rather than repeat myself endlessly on this interesting matter, here’s the blurb from her website: […] Click to continue reading this post
I don’t know if you’ve already heard about it, but the first commercial solar energy plant, (located near Seville, Spain) was inaugurated a while ago (30th March). It is an 11 Megawatt plant, called PS10 and:
…the project produces electricity with 624 large movable mirrors called heliostats.
Each of the mirrors has a surface measuring 120 square meters (1,290 square feet) that concentrates the Sun’s rays to the top of a 115 meter (377 foot) high tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity.
I got that quote from an excellent article here. You can read a lot more there about some of the future plans of the EU for solar power there. Go directly to the website of the company that built it, Solucar, for more information and images of the plant.
The 625 mirrors with the central tower, all glowing from the reflected sunlight, is quite […] Click to continue reading this post
So the planet hunter Corot has found its first extra-solar planet. It is a bit bigger than Jupiter, and orbiting awfully close to its sun-like star. Artist’s impression, from ESA, to the right. Click for larger.
From a BBC article by Rebecca Morelle:
The new body is called Corot-exo-1b and can be found 1,500 light-years away in the constellation of Monoceros.

NPR’s Robert Krulwich does it again. As part of a long special series that NPR has begun about carbon and climate change, he starts out with a really really good piece (with his usual level of humour and sound effects – and graphics on their website) on carbon. What is it with carbon that makes it such a special element to us, our biology, our planet? What is it about carbon that makes it so happy to stably bond into chains (storing energy), and so stably that we get huge reserves of energy stored underground in the form of fossil fuels (oil, etc).
