Leonardo Da Vinci's Mind Match

Lenardo da Vinci seemed to pay lot of attention to nature and God's work. He was not only a painter but also a great scientist.
Along with many other theories, he also formulated a theory about relationship between size of tree's truck and the combined measure of its branches.
According to da Vinci's theory "the squared diameter of a tree’s trunk is equal to the squared sum of the diameters of its branches. Moreover, if a trunk is split into two sections, the sum of the thickness of all the branches coming off of one of the section is equal to the thickness of that section of trunk."

A French researcher Christophe Eloy, a visiting professor at the University of California at San Diego and a specialist in fluid mechanics, now claims to have proven this theory mathematically.
Scientist hopes that his findings would have several applications including better understanding of the mechanism of how plants grow and resist outside elements.
