Dig this: The physicist Richard Taylor has developed a technique for authenticating Jackson Pollock “poured” paintings — by analyzing their fractal dimensions.
Taylor, who also has a degree in art theory, got interested in Pollock’s work back in the 1990s. He suspected that Pollock’s famously chaotic paintings — created by the artist standing over the canvases and dripping paint — displayed fractal mathematics: They had self-replicating geometry, such that the larger shapes in the picture were similar to the tiny shapes you’d see if you looked at closely the edges of the splatters. He put computer-generated grids over images of five Pollock splatter paintings and, sure enough, there they were: Two sets of fractal patterns, one that resolved on a 5 mm scale, and another on a 1 mm scale.
There were two reasons to suspect that Pollock’s paintings might obey fractal geometry. Moving around a large canvas laid on the ground, the artist let paint fly from all angles, using his whole body. Human motion is known to display fractal properties when people restore their balance, says Taylor, and films of Pollock seem to show him painting in a state of ‘controlled off-balance’. Second, the dripping and pouring itself could be a chaotic process. [snip]
“Pollock was in control,” says Taylor. The large-scale fractals are a fingerprint of the artist’s body motion, he notes. “But the small-scale fractals are also to do with his choices — his height over the canvas, the fluidity of his paint, angle and force behind the trajectory, and so on.”
Cool enough, eh? Now dig this: Last year, 32 new “poured” paintings — purportedly by Pollock — were uncovered for the first time. Art historians have been arguing heatedly over whether they’re real Pollocks, because the official Pollock authentication board was disbanded in 1995 when it was assumed there were no new Pollocks to find. One of the former members of the board is launching a new show of Pollock’s work that includes some the new-found paintings; after seeing one of Taylor’s papers on his Pollock-fractal work (in Pattern Recognition Letters, a just awesomely-titled academic journal), the art expert sent Taylor six of the new paintings to analyze.
His verdict? They didn’t display Pollock’s distinctive fractal patterns. While Taylor says his technique shouldn’t be regarded as a final word on Pollock authenticity, it’s a pretty nifty use of fractal math.

My Xbox broke, and I was trying to Google some possible technical solutions, when I noticed that Google appears to be encouraging me to make a typo. I suppose it’s possible that Google’s algorithms know that typing “wont” instead of “won’t” would produce better results.

On the other hand, when I tried the test for multitasking, I was pretty abysmal. I performed worse than people who identify themselves as heavy multitaskers, and those who identify as low multitaskers.

I finally got around to trying out the interactive “test your distractability and multitasking” page at the New York Times, which they put up alongside their story earlier this month about how computer distractions are eroding our lives.
According to the test, I guess I have good focus — I’m not very distractable!
