quadricode - Yes. Thanks. Lichtenberg figure<http://en.wikipedia.org/wiki/Lichtenberg_figure>is very interesting. But it doesn't look like lightning. But now I think I get it. Lightning must be a slow crack. The Hans Haverman link is perfect: the ice is is slowly melting rather than shattering. Oak trees grow very slowly. Lightning, even though it seems really fast, must be traveling a lot more slowly than it could in other conditions. And that helps explain, I think, what was confusing to me about blood vessels. The fractal changes. A fat vessel like the aorta looks like the tree in the Hans Haverman ice link: smaller branches jut out at more perpendicular angle to the main branch because that's most efficient. But at the capillaries blood vessels are messy and odd — like an oak. I think that's it. Kind of like how meandering country roads don't look like miniature freeways. The fractal isn't uniform. Real blood vessels don't look this <http://www.flexilearn.com/?p=9> this for example. On Sat, Mar 5, 2011 at 6:08 PM, <quadricode@gmail.com> wrote:
How about this Lichtenberg figure?

I actually expected a crack in ice to look a lot more like lightning but it's completely different.
How about *these* cracks?
