Long, long ago, before anyone even dreamed of the concept of fractals, Leonardo Da Vinci envisioned them. In the voluminous surviving pages of Leonardo Da Vinci’s notebooks can be found the first detailed study of the fractal branching rule in forest ecosystems. Da Vinci, that incomparable renaissance genius, included in his analysis detailed diagrams illustrating the rule. Amongst present day environmental scientists, it is now well known that this rule can be used as a predictive tool. Briefly, the rule states that starting from the trunk of a tree; daughter branches and twigs have the same combined cross-sectional area as the branch from which they originated. Detailed research (some of which has been mine) has now demonstrated that this relationship applies to an entire forest system. An entire forest can be fractally modeled as if it were a single tree. This has enormous economic implications. Taking a census of an extensive forest system is very costly. Computer fractal branching rule models now exist, which vastly reduce the census costs. Also, these models allow calculation of the greenhouse gas adsorption capability of a forest. Today’s rendering uses Da Vinci’s actual fractal branching rule as an illustration of the way fractals can be found everywhere in nature. Everything from quantum physics, biology, geology, meteorology and on up to the formation of galaxies and galactic clusters consist of fractal structures. Here is the fundamental question: Why is this? The trite answers such as “fractals represent the most efficient packing structures” do not even begin to answer this question. It goes much, much deeper than that. Created in Ultra Fractal
