Jester at Resonaances reports on a talk by Jörg Wenninger about the progress at the Large Hadron Collider (LHC).
There’s information about the repairs, more thoughts about the accident last year, and somewhat frightening news about issues of quality control on some of the manufacturing of crucial parts that may haunt the entire project for some time to come. […] Click to continue reading this post
I just learned from Phil’s blog that the Galileoscopes I mentioned to you some months back (remember? International Year of Astronomy? Not just Darwin year?) are ready for shipping. There were issues with production at first, but now they are ready. The key issue right now seems to be that they are in danger of having to stop production of these lovely things if they don’t get lots of orders by May 31st. Ack!
So please please consider sending in a order for one or a few. Imagine what a delightfully unusual gift it would make for someone. Either someone you know, or someone you don’t know like a neighbour, your local school, church (yes!) or community center, or… even that special someone who you’d like to get to know – what an icebreaker, eh? Here’s a picture from the site of what a happy owner’ll have after assembling it:

I’ve just finished two days of staring for long stretches at the computer screen, reviewing all my footage for the films, (see also here) making careful notes about which takes I like, which I don’t, which are salvageable, which are a total mess, suggestions for cut away shots, transitions, other edits, etc, etc, etc… These notes are for my film editor, who will now take the hard drive of all the footage to begin cutting the first rough versions of the films.
It was a time-consuming process, with the additional complication from the fact that the Industry is in some disarray when it comes to high definition (HD) formats. Largely due to the explosion of technology, the move to, and the demand for the format from the consumer TV world, there is no universal standard for how different camera manufacturers (and even the different models of a given manufacturer) save the files they make, and for how to get those files safely and reliably off the camera and on to your computer in a way that allows you to view them. Different flavours of […] Click to continue reading this post

Yesterday saw my annual stint of judging at the California State Science Fair. Somehow it managed to sneak up on me this year, and so I did not get to do what I planned to do, which is encourage one or two scientist/engineer friends of mine in the area to sign up to get involved, since it is such fun and quite rewarding (ahem: Michelle P., Amy M., mark your calendars for next year! I’m going to come a-calling…) See earlier posts (e.g., here, here) for science fair descriptions, and the fair’s own site with lots of photos each year is here.
(Ok, there’s the whole getting up in time to arrive there by 7:00am or so. That bit is less than good, perhaps.) I arrived a bit later than 7:00, due to some breakfast procrastination that 
I somehow sometimes manage to do even when I wake up with plenty of time (a whole hour this time) to get ready. My plan to simply set out by 6:10am and pleasantly walk/bike and bus down (my usual mode) was thwarted by this and so I had to take a somewhat quicker mode of transport, launching out of the batcave in a hurry at 6:50am! By 7:15am the parents and students in their SUVs and minivans were arriving at the California Science Center in droves, and so this meant that parking was a bit more of a challenge that it would have been 15 minutes earlier. But as you can perhaps see on the right (click for larger view), it all worked out in the end… ( 🙂 )
Here’s a shot of the annual morning briefing of the volunteer judges (all well fed, […] Click to continue reading this post
Why is everyone excited about this picture?
Actually, there’s a dot on the bottom left quadrant. What is it? What did the excellent photographer Thierry Legault manage to image?
Well, it’s wonderful: […] Click to continue reading this post
Tomorrow is the Big Day. For what? The launch of Planck and Herschel – Major new windows on our universe. Keep your fingers crossed for luck!
They’re on the launch pad right now. See here.
So, what are the missions and objectives of these fine spacecraft, I hear you ask.
Well, from the Planck site: […] Click to continue reading this post
The (spoof) phone-in “Down The Line” on Radio 4 last week was brilliant! It featured a guest talking about science, with a particular focus on his dislike of string theory, and with the callers (the usual brilliant cross section of UK phone-in archetypes) taking the discussion all over the place: Doctor Who, soccer, “female scientists”, gay daleks, and so on and so forth.
My favourite question: “Why do they have to keep mucking about with the […] Click to continue reading this post
The space shuttle mission launching today (around 2:00pm ET) has a very special task. It is going to take some astronauts up to do some crucial repairs (see story here) on the Hubble Space Telescope. It is the last such mission (Hubble will be retired into the Pacific eventually) and has been long awaited. Please keep your fingers crossed for a successful mission to keep such an important scientific instrument working for another five (or so) years to teach us more about the universe. (Go to the Hubble site here.)
NPR had a rather good piece about the special tools that were designed to allow these repairs to be carried out. The point is that the astronauts are not just swapping out parts or modules that were designed to be swapped out (like you do a light bulb, a shower head, or a shaving foil), but they have to go in and take out things deeper […] Click to continue reading this post
So, apparently there is physics in the upcoming huge film Angels and Demons (and presumably the book). Lots of it. I did not know that until recently. So imagine my surprise a few months ago when I got a message from a producer (Natalie Artin of Prometheus Pictures) of a documentary about it, asking if I’d like to contribute, talking about aspects of the physics.
They wanted me to talk about anti-matter. This is as a result of finding a blog post of mine over on Correlations, entitled “Not Science Fiction”, which starts:
Anti-matter. Seeing the previous word, you immediately glance back at the title, right? Strangely, it has been 80 years since the discovery of anti-matter, and we use it routinely in our technology. Nevertheless, anti-matter is still thought of as something from science fiction (and mostly bad science fiction at that).
It all goes back to one of my favourite theoretical physicists, Paul Dirac, and you might like how he found it (roughly). He essentially did it by […]
I agreed to talk, if I could focus on one of the main issues of my post: That anti-matter is not weird stuff of science fiction, but actual routine science…. so routine that it is used commonly in medical diagnosis, for example. The “P” in PET scans stands for “positron”. The positron is the anti-electron. (The “E” does not […] Click to continue reading this post
[Update: It is Sunday night, not tonight. See upcoming post.] If you’re a fan of the Da Vinci Code and interested in the new film Angels and Demons (or even if you’re not), do check back here tomorrow (Friday) for some news of something on TV tomorrow night about it. … Click to continue reading this post
Remember a couple of weeks ago I was mentioning an outbreak of schoolboy(-like) giggles from my physics 408b class due (it turns out, if you did the homework on the equation) to some audience-perceived off-colour hidden joke in some of the material I was presenting? (I’m still a bit embarrassed since I had no intention of making the joke they saw.) Well, just a couple of days later, I was witness to it again, but this time it was in a lecture by someone else, and the audience was mostly professors, and it was one of my esteemed colleagues who couldn’t help himself and broke out giggling. Well, actually, there was a short loud guffaw which burst out. So you see, even the fine upstanding citizens can submit to juvenile giggles.
Let me tell the story. We had the eminent evolutionary biologist Patricia Gowaty (UCLA) give an excellent talk entitled “Darwin and Gender”, as part of the College […] Click to continue reading this post
I had a lot of fun at this year’s Jet Propulsion Laboratory (JPL) open house. I’m happy to report that there were, once again, lots of people wandering around looking at the displays and demonstrations, asking questions, hanging out, and so forth, and an impressive turnout of JPL staff answering questions and being very enthusiastic about the science (something which is easy to do because it’s such an excellent topic!). I’ve made a video for you that is coming up at the end of this post. (Click on stills for larger views.)
There was the usual huge emphasis on planetary exploration with rovers and robots and so forth – this seems to capture the imagination of everyone, so why not? – but I was more than a little surprised to find virtually no showing for the Planck mission. There was one poster somewhere, but no booth, no model, no description of the truly amazing science that it will do in unlocking more about the origins of the entire […] Click to continue reading this post
