If a tree falls on Ottermann, and no one hears it, does anyone care?

Trees. Large perennials with woody stems that come in many varieties, that most of us find pleasing for any number of reasons.

Da Vinci. A true renaissance man.

What do they have to do with each other? Well, have you ever heard of 'Da Vinci's Rule of the Trees'?

In short, it states that: The sum of the diamater of all branches and limbs equals the diamater of the trunk.

In a slightly longer form: If you measure the diamater of every limb or branch that is not part of the trunk, the sum total of them all added up will equal the diamater of the main trunk.

For a long time, people just nodded and said, "Uh-huh, sure.". No one really thought to test it until a physicist named Christophe Eloy started experimenting with it. Trees are fractal in nature, meaning the patterns formed by the larger parts, (trunk and limbs), are repeated in the smaller parts. (branches) Eloy then made models based on the fractals of trees and put them in a wind tunnel. When he finally had a tree that replicated a real tree, he did his measurements. Da Vinci appeared to be correct.

In the field, studies have shown that many trees across several species follow this rule. Scientists aren't sure why trees follow this rule, but they find that it holds true when tested.

Methinks Mother Nature is a little OCD.
