The responsibility of Twitter updates got you down? D’you think about tweeting but never actually get around to it? Never fear, Adam Wilson is here. The University of Wisconsin–Madison biomedical engineering grad student removes the clunky and outdated interface of keyboard and lets his brain tweet for him. That’s right, he straps an electrode-coated swim cap to his head and watches as letters scroll across his computer screen. When his brain recognizes the letter he wants, the swim cap knows and uploads it directly to Twitter. What’s the meaning of that F to which you’re inexplicably drawn? Why does your attention keep traveling toward the S? Now, thanks to Adam Wilson, you can become conscious of your unconscious, and make sure everyone else in the Tweetosphere is conscious of it too.
Genius Tester #2: Bridge and Torch
Four people come to a narrow bridge at night. Between them, they have one torch, which has to be carried in order for anyone to cross. Only two people can cross the bridge at a time. Person A can cross the bridge in 1 minute, B in 2 minutes, C in 5 minutes, and D in 8 minutes. When two people cross the bridge together, they go at the slower person’s pace. How can they all cross the bridge in 15 minutes or less?
