Blogs / Bad Astronomy

Aha! The video I mentioned the other day featuring Watchmen advisor Jim Kakalios — about nerds running the planet — is now on YouTube! So I have embedded it below for those who are too busy to click an actual link.

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?

[More pictures are in my Flickr Snow Dalek set.]

Jim Kakalios was the science advisor for the Watchmen movie, and wrote a book called The Physics of Superheroes. I met him briefly when we both spoke at the National Academy of Sciences about new ways to engage the public about science. He’s a nice guy.

He’s also a funny one, and a canny one. He was asked to give the 2009 convocation address at the University of Minnesota (sorry, the video is not embeddable, so go there and watch it), and he talked about geeks and nerds. I think he hit the right note. We do run this planet. "Revenge of the Nerds" was more than just a movie, it was a primer for the future of nerddom.

You might as well face it. If you’re reading my blog, you’re a nerd. Be proud. I am.

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…

[Note: NASA is trying to launch the new ARES I-X rocket, scheduled right now for 10:54 Eastern time. As I write this weather is not so great so it may be a scrub, but follow me on my BANews feed on Twitter for the latest!]

I don’t usually talk about iPhone-specific stuff, but as it happens I own (a spiffy pink) one, and this is pretty cool.

NASA just released a new app for the iPhone, and I like it. It has info on missions, pictures, videos (links to YouTube), and more. It’s a pretty slick app, professionally put together.

You can filter the missions to look at using categories like Earth, Solar System, Moon and Mars, and so on. It tells you when it launched, what the mission elapsed time is (which is pretty nifty), and from there you can access images and video related to the mission. Not only that, but if you tap the Earth icon when a mission is displayed, it will show you a real-time map of the location of the spacecraft over the Earth! I checked it using the space station against the info at Heavens Above, and it matched closely.

If you start from the home page and tap the image icon at the bottom, you get a choice of pictures from NASA’s Image of the Day as well as the venerable Astronomy Picture of the Day. I checked those and they were up to date with the current day’s images, too. Nice.

Videos appear to be in reverse chronological order, which is nice. Also, if you tap the RSS symbol you get the NASA Twitter stream. Very well done.

Any complaints I have are minor. It refers to Fermi as GLAST, which was its name before launch– a year ago. Some missions are missing, and I hope they’ll put them in when they update the software. Swift would be a great candidate for this, especially if they give real-time access to when it sees gamma-ray bursts. Things like that would turn this app from something cool into something extremely handy. Also, it seemed a little slow to get started, even using 3G. I turned on my wireless connection and it zipped right up though.

Still and all, it’s worth the download. If you’re a geek like me (and c’mon, admit it: if you’re reading this blog in the first place, it’s too late to hide it) you’ll enjoy it.
