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:

Down The Line on Strings
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 Right Tools for the Job
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
Glad it is Mother’s Day
It is Mother’s Day in the USA (a few weeks after the UK one – this means I send two sets of greetings to my mother each year). This year, rather than a rose, I’m going to put up a member of the gladiolus family, since one of mine put on a stunning display two days ago and deserves to be shared.
I almost forgot to carry out my plan to do this post, as I’ve been shooting Click to continue reading this post
Tales From The Industry XXVIII – Angels, Demons, and Antimatter
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
Check Back
[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. Apparently there is actual physics playing a role in the film/book. (I play a small role in this film about the movie, which will be aired tomorrow.) But I am way too tired now to blog it (and the shooting thereof), and so will do so tomorrow. So check back.

Professors Do It Too
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
Locomotion
There’s something quite marvellous about trains. You can sit and think, work, or play while it slowly extracts you from your city and gently inserts you into another. There’s no mess and fuss to do with cars and so forth, and the scenery is almost always interesting, whether it be the backs of people’s houses, where you can see washing lines, pools, gardens, gym equipment, horses and llamas (no I am not joking), 
or those businesses and infrastructure that we don’t often keep on the high street – any number of strip clubs, storage for trains and school buses, lumber yards, power stations, public storage units, yards with endless amounts of rusted metal – or farmland growing crops (sometimes in interesting geometrical arrangements), ocean, boats, piers, oil refineries, and of course surf and beaches. (I’ve some video clips of some of this. Perhaps I’ll edit it all together into a video for you later.)
You can look up from your thoughts, work, or leisure from time to time and gaze out over any of this for a while, drinking in the scenery at will. I find that people on the train are very friendly -almost ridiculously so- almost as though either the train attracts a certain type of person who is conducive to this type of mood, or there is something Click to continue reading this post
Yesterday at JPL
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
John Oliver at the LHC
Of all of the videos I’ve seen of people visiting the Large Hadron Collider (LHC), this one is the funniest by very far… yes… it’s John Oliver again:

The probability discussion is just priceless…

Fun at the Museum Tonight!
Last month’s First Friday was just great! I think I finally understand where LA goes on a Friday night. The Natural History Museum was full of people wandering around looking at the exhibits, going on the tours and listening to the talks (all were at capacity!) and just hanging out listening to the musicians or the DJs. Reminds me a lot of that Josh Ritter event I went to a while back, but so much more extensive, since Click to continue reading this post
JPL Open House!
It is that time of year again. The Jet Propulsion Laboratory is having an open house this weekend, 2-3 May 2009! This is excellent news, as I’ve been very impressed with the open house in past years, and I am pleased that it has continued. There’s a real dedication to doing it well, with lots of volunteers giving of their time to make it a really high quality event. I recommend it. Their event page is here. You might find my description of one of the visits I did useful as a guide to what to expect. It is here.
Maybe see you there….
Enjoy!

Products of Culture
Well, on day ten (see the earlier post, and also this one) I had no choice: I had to find the time to make some bread soon. I decided to try the default recipe, even though it was not much like the bread I make. One should try new things. The good news was that it is quick and easy to do, and so I did not need to set aside a huge amount of time. So after a bit of prepping:
…it was popped into the oven. Recipe (“remaining batter” is about 1.5 cups of the yeast starter left over from the doings on day ten… see earlier post) for this “Amish Friendship Bread”:
