Thinking of math is proven to hurt (and other things we didn't cover)

Seemingly, there is no connection between Cylons, water, the Kinect, and math. But in fact, there is! They're all connected to very cool things that happened recently, but we didn't get a chance to cover. Don't miss today's edition of GeekBytes!

A Cylon Centurion carved from pumpkin detects approaching trick-or-treaters [YouTube]

As we saw in the last week or two, Halloween reallybrings out people’s creativity. But nothing I've seen this year so far matches up to the sheet coolness of this pumpkin Cylon. If you've ever watched Battlestar Galactica (and I'm sure you have), you will immediately recognize the distinctive light and sound effects of a centurion. The pumpkin is connected to two Arduino boards, an ultrasonic sensor that detects when approaching enemies (or, more likely, just people), and iPod amplifiers to play the sounds. And it has a plan.

Interactive Kinect sculpture turns the ceiling into water [Vimeo]

Water installments, such as the stand-in-the-rain-and-don't-get-wet one we told you about recently, are lots of fun. But what about an interactive sculpture that makes it look like you're under water, when you're in fact standing in a completely regular room? Such is artist David Bowen's “Underwater” project, which makes use of Microsoft Kinect, data from moving wave patterns, and no fewer than 486 motors. The result is a moving grid on the ceiling that makes it look as though you're under water. Original! [via Designboom]

Thinking of math is similar to expecting physical pain [PLoS One]

A new study about math anxiety from the psychology department in the University of Chicago found that for people who suffer from math anxiety (and let's face it, don't we all?), thinking about math triggers the same neurological response as anticipating physical pain. Surprisingly, doing that actual math doesn't trigger the same response--it's only the anticipation of math that hurts. So next time you want to avoid math, you have a real scientific excuse!
