META-QUESTIONS CAN REVEAL FRACTAL PATTERNS

A shoreline is the same when you look at it from space, from a mountain, or on the shore. Tree branches have the same structure at multiple levels. The level of the detail hardly changes with each iteration. We call these fractal structures. It is the same with the human lung, in art, etc. This self-similarity is known as a fractal pattern.

There are so many fractal structures in nature that it is hard to choose where to begin. If we begin with ourselves, many of our internal organs have a fractal structure. The biggest example can be the lungs. The reason for this is in the need for more exchange surface for the oxygen and carbon dioxide. The surface of the brain is folded in a fractal structure. Arteries also have a high fractal dimension so that their coverage is more uniform. They may have some iterative "rule'' that grows them in such a way.
