Fractal or Fake?
Novel art-authentication method is challenged
Julie J. Rehmeyer
Science News Online"Jackson Pollock couldn't possibly have been thinking of fractals when he started flinging and dripping paint from a stick onto canvas. After all, mathematicians didn't develop the idea of a fractal until a couple of decades later. But if one physicist is right, Pollock ended up painting fractals anyway. And that mathematical quality may explain why Pollock's seemingly chaotic streams of paint come together into an ordered, beautiful whole, and why the technique brought Pollock acclaim as a master of American abstract painting.
PAINTING UNDER A MICROSCOPE. Fractals are objects that look the same under magnification as they do as a whole. One researcher says that Jackson Pollock paintings have that property.

A fractal is a geometric structure in which the shapes at a large scale reflect the shapes at a small scale, forming an interlocking set of patterns that nest inside each other like Russian dolls. Approximations of fractal structures have been noticed throughout nature. For example, the overall crystal structure of a snowflake looks remarkably like the structure in a single arm. And the ridges of a mountain range jut into the sky, forming patterns similar to the crags thrusting out from a single peak.
In the same way, the web of large streaks of paint across a whole Pollock painting resembles the finer network covering a small section, Richard Taylor of the University of Oregon in Corvallis reported 8 years ago. He recently used these observations to investigate whether newly discovered paintings are really by Pollock, and hence worth millions of dollars, or whether they're destined for a garage sale. He proposes that the fractal nature of the paintings illuminates what made Pollock a genius rather than a mere slinger of paint.
