Someone with a little time on their hands, feeds some AC/DC into their laser (OK, technically the waveform of the music), and watches the trapped atoms “dance”
The low-pass filtering means it responds more to the bass and drums.
This isn't The Onion?
Oh, wait. It’s just the time-honored (sorry, honoured) tradition of writing a headline that has the opposite implication than the actual story.
Call for creationism in science
Professor Michael Reiss says that if pupils have strongly-held beliefs about creationism these should be explored.
Rather than dismissing creationism as a “misconception”, he says it should be seen as a cultural “world view”.
Teachers should take the time to explain why creationism had no scientific basis, Prof Reiss said.
He stressed that the topic should not be taught as science.
Yeah, I can see how summing that up should be worded as a call for teaching creationism.
Obvious to the Most Casual Observer
While I was watching the political convention last week (and the week before as well, actually), it astounded me at how often the speakers would resort to obvious logical fallacies. I counted five false dichotomies and four straw men within the Sarah Palin speech alone. Now, just to not be political: I’m sure Joe Biden also committed a whole bunch of logical fallacies, I just didn’t think about it until I heard Sarah Palin ‘poison the well‘ against Barack Obama.
Just discovering this, are we? That’s one reason that I dislike politics, and I was under the general assumption that others capable of spotting such arguments (e.g. scientists) felt the same way.
Hi-Tech Food
I’ll bet the slices are all the same size, but it’s disappointing that the pieces still stick to each other.
Print me some toast. The scan-toaster.
The toaster utilizes a network of toasting “modules” — hot wires that rotate within a 30 degree radius — that burn the image or text you have selected onto the delicious slice of your choice.
Not commercially available, though.

The blackboard of anonymous questions
There are blackboards in the common room of my department. They don’t see much use.
We were joking at tea today that people ought to write problems they want solved or questions they have on the blackboard, and other people could write the answers. Surely this has been tried somewhere. How did it work?
Me Fail Topology? That's Unpossible!
Mmmmm. Peeeeople.

I think it was the right call to re-shoot the scene. The original was, “Soylent Green is Green Dye #3 and peeeeeople! It’s dye and peeeeople!”

Cory Doctorow’s Cipher Wheel Wedding Rings
Cory Doctorow wanted a secret decoder wedding ring, and he asked me to help design it.

[N]ow it’s time to create some cryptographic applications for the rings. Cory and I are holding an open contest for the cleverest application.
