Pride and Science
Central London featured two important events this past weekend. First was the annual Gay Pride Parade, a riotous and joyful procession of rainbow flags, pink clothing, and (mostly) ill-fitting dresses on very large people. Sadly, the only thing that marred the good-natured, family-friendly event were the stupid protesters. But it was wonderful to see that…

Physics for Fiction
I spent a few hours last week with a bunch of science fiction writers, giving them a tutorial on modern cosmology as part of the (first) “Physics for Fiction” workshop organized by my Imperial Astrophysics Colleague Dave Clements. The participants were some very big names in modern Science Fiction, and some hot up-and-coming writers, including…

Come on Baby Let’s Go Downtown
·
The summertime British music scene is taken over by a series of festivals up and down the country; the biggest and most famous is Glastonbury, but the same weekend London’s Hyde Park holds the somewhat scaled-down (no sleeping over in tents) “Hard Rock Calling“. I arrived too late for the Pretenders, whom I had last…

Ornette Coleman’s Meltdown
·
The annual Meltdown festival took over London’s South Bank Centre this week. I saw Yo La Tengo‘s rock ’n’ roll Q&A, and unfortunately missed a performance by David Murray, one of my favorite saxaphonists. But the highlight was curator Ornette Coleman himself, in an evening dedicated to his “Shape of Jazz to Come”, the record…

Another launch
·
Not all CMB (Cosmic Microwave Background) experiments get launched on a rocket. There’s a long history of telescopes flown from balloons — huge mylar balloons floating over 100,000 feet in the air. MAXIMA and BOOMERaNG, the first experiments to map out the microwave sky on the sub-degree scales containing information about the detailed physical conditions…

Exam nightmares
The students in my cosmology course had their exam last week. There’s no doubt that they found the course tough this year — it was my first time teaching it, and I departed pretty significantly from the previous syllabus. Classically, cosmology was the study of the overall “world model” — the few parameters that describe…

In the Sky (at Night)
·
Despite my almost eight years in Britain as an astronomer, I suppose I have to be embarrassed to admit I’ve never actually watched “The Sky At Night“, apparently the longest-running show on television (possibly in the whole world, not just the UK). But I’m watching this evening’s episode, mostly because I’m on it. I was…

Conditional Probability explained
·
Before it happened, I would have said slim. But since it happened, 100%. –Lawrence Fishburne, CSI, on the chances of being hit in the head by a tortoise dropped by a bird of prey. (This goes well with Ted Bunn’s exegesis of the Daily Show’s brief foray into probability theory for their segment filmed at…

Launch!
·
Cross-posted on Andrew Jaffe’s Blog and the Planck Mission Blog. Planck and Herschel are en route to their orbit at L2! We were about 7.5 km from the launch, at the “Agami” viewing site. Here is my golden ticket: We all milled around for half an hour, snapping pictures of friends, eminent scientists, and at…

Launch Blog — Day 2: Rollout
·
Cross-posted on Andrew Jaffe’s Blog and the Planck Mission Blog. Today we saw the rollout of the gargantuan Planck/Herschel Ariane 5 rocket, when they move it from its assembly building to the launchpad. Spectacular! There are plenty more pictures, and some movies, which I’ll try to edit and post shortly. At the end of the…
