"Formally speaking, fractals are infinitely complex patterns that are self-similar across different scales. But, in an echo of their geometry, fractals can help us better understand the world on many levels.
Let’s start with the familiar: fractals in nature. “They are all around us – in trees, mountain ranges, river deltas and so on,” says Dave Feldman at the College of the Atlantic in Bar Harbour, Maine. "Such ubiquity makes sense because of the way fractals are made: “a simple iterative process – repeated folding or branching – can produce fractals”, he says.
The inside of your lungs is fractal for a reason:
such arrangements cram a huge surface area into a small volume of space.....maximizing the area of tissue that can absorb oxygen."
