III. FractalField Theory
(1/3 Pages) 






A human body is created as a fractal structure. Specifically, a human body consists of organs; an organ consists of large leaves; a large leaf consists of small leaves; a small leaf consists of cell units; a cell unit consists of cells. This structure consists of differentsized units having "selfresemblance," so that it can indicate that a human body is created as a fractal structure.
1. Representative Fractal Structures in Nature
First of all, let us pay attention to three representative fractal structures in nature: a tree, a river, and a coast line. A fractal structure has selfresemblance. As shown in the figure below, each of the three things consists of differentsized elements having selfresemblance, so that it can be regarded as fractal structures. Specifically, branching of a tree shows selfresemblance; traveling of a river also shows selfresemblance; a coast line shows selfresemblance. Thus, a river, a tree, and a coast line can each be considered a fractal structure. 






(A river, a tree, and a coast line are representative fractal structure in nature.) 




(a) Two and ThreeDimensional Fractal Structure
Fractal structures in nature can be classified into two types, which are two and threedimensional fractal structure. In the examples above, a river and a coast line belong to twodimensional fractal structure; on the other hand, a tree belongs to threedimensional fractal structure. This classification is important for us to analyze what fractal structure a human body has. 




(b) Fractal Structure Seen in A Tissue
Paying attention to a tissue enables us to find out easily that it is created as threedimensional fractal structure. A tissue is created as a threedimensional fractal structure, and can be divided into two types of fractal structures: vertical and horizontalfractal structure. In a tissue, the blood vessels form vertical fractal structure; on the other hand, the cells form horizontal fractal structure. The figure below shows these special characteristics of a tissue. 






(A tissue is made from two kinds of fractal structures, and which are vertical and horizontalfractal structure. Vessels form verticalfractal structure; cells form horizontalone.)
