John and Dawn:
Thanks for sharing that amazing photo with us. Although I have never seen this structure in a meteorite, this type of "fractal" is quite common in nature and the physical world. Typically these patterns can be generated with a simple formula, called the Mandelbrot Set, by the expression:
Z = Z (2/n) + C
(n+1)Any search engine will yield numerous sites dedicated to the Mandelbrot Set. In fact PBS did a special on it with Arthur Clarke as the host, a few years ago. Seemingly unrelated phenomenon such as tree patterns, animal structures, and the patterns one gets when applying pressure to your closed eyes can be described by this formula and its iterations. If you decide to do a "search" on the net for Mandelbrot, be prepared to spend an hour or so being amazed ,it's that addictive!.
