This is, to me, serious evidence that the robot age is right around the corner. For a long time now, it’s been easy enough to solve the Rubik’s Cube problem on a computer. But solving a real cube using a computer, that’s a different matter. First you have to take pictures of all the sides. Then you have to physically manipulate the cube according to your algorithm. The interface to the real world is always a pain.
But here is a robotic Rubik’s Cube solver built out of Lego Mindstorms components. The guy who built this is a hardcore hobbyist, but still, this is relatively cheap stuff, as robots go. Now watch…
You know you’ve struck a cultural nerve when you inspire not just one but dozens of parodies and copycats. It’s hard to say, for instance, why the Lazy Sunday video inspired so many spin-offs, but YouTube tells me there are 278 as of this writing.
Across the Pond, the Keep Calm and Carry On poster hits all the right notes to make it a cultural phenomenon in the UK. Originally created in 1939 to steel the British public to the stresses of the coming war with Germany, it was rediscovered in 2000 and has been a gold mine of merchandising and parody ever since. Its nostalgic evocation of the steady resolve of bygone days has mated with its easily mocked earnestness to breed a deranged litter of spin-offs.
Via BlogLESS I came across Christina Agapakis’s Meme Tree. She’s a biologist, so as you might expect, she’s built a nice phylogenetic tree. Like her, I’m amused by the evolution from simple transpositions like “Keep Calm and Rock On” to “Drink Lots and Pass Out” to more ironic assertions like “Change Words and Be Hilarious”. From there, it’s a short step to the self-mocking “Run Out of Ideas and Make a Parody” and the meta-self-mockingly abstract “Meme Meme and Memey Meme.”
Great news! Dan Schroeder, the physics professor whom some of you will remember from his excellent reviews of iPhone astronomy apps, has written his own astronomy applet. Give it a look.
Why write another astronomy program? Here’s Dan’s answer.
To be useful to most of my students, a simulation program has to be (a) free; (b) delivered through a web browser, with nothing to download or install; (c) easy for beginners to understand; and (d) convenient for showing the motions of the stars and other objects with respect to earth’s horizon.
It’s a lot of fun to play with, and I like how Dan notes that his UI was partially inspired by H.A. Rey’s stargazing books, of which I too was, and remain, a loyal fan.
Here’s a little slice of Ned’s Ancient History: I artfully surfed the dying wave of the Cold War. I paid for an expensive education with the help of an Air Force ROTC scholarship, thanks to Ronald Reagan’s extravagant defense bender. After three years of thoroughly enjoyable active duty, I emerged from the Air Force earlier than expected, thanks to George Bush the Elder’s frantic defense downsizing. Between those bookends, I pulled down the Berlin Wall, caused the Soviet Union to collapse, and co-wrote the smash hit “99 Luftballons”. Which is to say, I came of age in the 80s, and I wore the blue uniform. And I remember the Strategic Air Command (“Peace is our profession”). So does my buddy JMike, who, like me, was a Cold War cadet. For a while, back in the day, he actually worked at SAC Headquarters at Offutt Air Force Base. He was a weather guy, and one day he coked the WX build. I’ll let JMike explain the significance of the phrase. I like this story, and I want you to know that I specifically requested that JMike include the bonus phrase “spooge jar”.

If you have any interest in synthetic biology, Nature Biotechnology has been kind enough to A) devote a special issue to the topic and B) make it available for free. I first learned about this on Rob Carlson’s Synthesis blog because he’s the author of an article on the economics of DNA synthesis (PDF).
I also recommend the survey by Lu, Khalil, and Collins: Next-generation synthetic gene networks (also PDF). Taken all together, the issue communicates a sense “We’re moving faster and faster” combined with “Jesus this stuff is complicated!” Commercial breakthroughs won’t come quickly, but it’s hard not to be impressed with the progress being made.
For an indication of where things are headed, look at the projects being built by student teams for the International Genetically Engineered Machine (iGEM) competition. Browse through the abstracts here and remind yourself that these things (these organisms) are being built by undergraduates in a matter of months. The team from Valencia is building the Valencia Lighting Cell Display (iLCD):
We are making a “bio-screen” of voltage-activated cells, where every “cellular pixel” produces light. It is just like a bacterial photographic system, but it’s digital. Within seconds, instead of hours, you can get an image formed of living cells.
I recall doing much less impressive things with my college projects.
Font designer Mark Simonson does an occasional blog piece called Typecasting (or more recently Son of Typecasting) in which he skewers films for the anachronistic foibles in their fonts. Did you know, for instance, that the steam pressure gauge on James Cameron’s Titanic was set in Helvetica? Crikey! That font was sinking 45 years before it was invented!
It’s a professional hazard. Just as Mark Twain could never look at the Mississippi the same way once he became a riverboat captain, Simonson can’t look at the tombstone in a Western without thinking How did Helvetica (1957) and Eurostile (1962) end up on a tombstone in the year 1885?
When it comes to language, regular readers of the Star Chamber will know that frequent contributor Alan Kennedy is the local expert. This week he has a few thoughts to share about actors and accents.

I can’t let this day pass without a salutation.
Mr. Groundhog has some good news to share: you made it halfway through the winter. It’s February, and you can actually sink your teeth into the afternoon sunlight. Yum.
People often remark that Thanksgiving is nice because, as holidays go, it’s not overly commercialized. Groundhog Day is humbler still. It’s not commercialized, AND nobody knows it exists. Or remembers it, anyway. Plus, it’s named after a rodent. Good luck with that one, Hallmark.
Happy Groundhog Day!
