One of the secondary goals of the Fermi gamma ray satellite is to look for the signature of dark matter. One idea for dark matter is that it’s composed of weird (and as yet undetected) particles called WIMPs (weakly interacting massive particles). A very odd property about them is that they are self-annihilating: when two of them touch, they turn into energy (and other, more easily detectable particles). When I first read about this several years ago I was pretty excited, because this is finally a testable hypothesis about dark matter.

My fellow Hive Overmind blogger and astronomer Sean Carroll writes that it’s possible Fermi has done just this. The data are not conclusive, but very provocative nonetheless. He has the details.

But I can’t resist adding that on The Big Bang Theory a few weeks ago, Raj and Sheldon were investigating building a detector to look for this very type of dark matter. I wrote David Saltzberg, the science advisor (whom I met on the set last month when I was visiting LA; more on him and that at a later date) and told him this, and he noted that I was right. Well, how about that! It had to happen sometime. Now, to publish…

A little while back, I made a sojourn to Los Angeles to get a few things done. You know, the usual for a science blogger: get a tattoo, hang out with a man crush, watch a live taping of a smash hit comedy show, meet and greet with TV execs.

Ho hum.

But one very cool thing that happened was that while watching the taping of one of my favorite shows, "The Big Bang Theory", I met David Saltzberg. David’s a physicist and astronomer who has serious bona fides in science. All that is very cool and all, but most importantly as far as I’m concerned is that he is the official science consultant on BBT. This is basically my dream job, so I’m very jealous.

But not bitter, because David’s a great guy. We met up on the set and immediately started chatting and having fun. And to cement himself in my pantheon of Very Cool People, he gave me his copy of the script so I could follow along with the show. Whoa! [Bill Prady, the co-Executive Producer of the show, also gave me a copy of the script for my daughter; Bill and David are the ones in the picture, courtesy CBS, from a UCLA article interviewing David.]

When you watch the show, take a look at the whiteboards littering the character’s apartments and offices. They always show a barrage of equations, notes, and diagrams. Those are all real! Yup, David’s work. When Sheldon and Raj argue over dark matter detection, or Leonard spouts off a line about physics, the core science is from David’s brain.

In a very wise and fun move, David has started a blog tying the science in the episodes to what’s currently known in the field, using BBT as a springboard to explain real cutting-edge stuff. It’s called The Big Blog Theory (also available en Español), and is a great read. if you’re a fan of the show, and a total science nerd (and as I always point out, if you read my blog then congrats! You’re a nerd) then you should put Big Blog Theory on your must read list. It adds a dimension to the show that otherwise wouldn’t be accessible except through ten-dimensional matrix transformations of the standard general relativistic metric, and while those are trivial to do it’s a step you now don’t need to take.

I am the king of all nerds. There can be no other.

What else is a guy supposed to do after a big snowfall and while waiting for "Waters of Mars" to air here in the States? And of course TLA helped, sawing the snowballs in half and shaping the body.

And hmmmm. Dalek and dork both start and end with the same letters. Coincidence?

Well, not literally, though that would be really amusing.

Jamie Hyneman and My Close Personal Friend Adam Savage™ were on the always-hilarious Late Night with Craig Ferguson show a little while back, and the video is on YouTube (note: somewhat NSFW dialogue):

Did you hear what Adam mentioned roughly six minutes in? The JREF! Woohoo! Adam is great about donating stuff from Mythbusters to the JREF so we can auction it off to raise money, and that particular gift was pretty special. Rarefied, you might say.

And, thanks to Greg Fish, I can add this:

Yer darn tootin’.

[Get it? Tootin'! Hahahaha!]

The BBC has announced that the new Doctor Who special, Waters of Mars, will air on BBC One on Sunday, November 15!

Squeeeee!

You can get more info on the BBC’s DW site. I’ve been without my dose of the Doctor for far too long, so this is welcome news. Of course, I did get a little bit of a David Tennant booster shot recently, so that helped…

For U.S. folks who get BBC America, the fantastic comedian, skeptic, and musician Tim Minchin will be on the Friday Night with Jonathan Ross show tonight!

Tim is brilliant; his performance at TAM London brought the house down. Jonathan Ross is something of a skeptic himself; he and his family attended TAML as well, and I found them to be funny, intelligent, and totally charming.

I can’t wait to see Tim on the show! I know it’s on YouTube already, but I’d rather wait and see the whole show [Edited to add: the video has been removed]. We’ve been watching it here at Chez BA and it’s really funny.

By the way, both Tim and Jonathan are on Twitter.

As promised, Brian Cox was on The Colbert Report last night, and hit it out of the park. The whole show was better than average (which is saying a lot) but Brian truly rocked!

If you missed it (and live in the States) the whole episode is online (Brian’s segment is about 13:50 into the episode). Comedy Central won’t allow embedding the whole show (sigh), and Brian’s segment isn’t separated out on the CC site, but right before he was on Colbert ragged on physics and the LHC:

In the full segment, they talk about Brian’s book Why E=mc², which was excellent. I’ll try to write a review of it as soon as I can. In the meantime, I do have to praise Colbert for his insight; as Brian points out he was correct in his ideas! I was cheering along with the segment. It still cracks me up that the smartest and most insightful commentary on TV is not from any of the "real" news stations, but from satirical shows like Colbert and The Daily Show. They have better science coverage than CNN, MSNBC and anyone else combined.
