Benoit Mandelbrot noticed the fractal geometry of certain aspects of nature (hence his book). Science has since discovered the existence of fractal patterns throughout diverse natural phenomena, in fields ranging from cosmology to biology to crystallography to economics. In some cases, the patterns are readily apparent in physical structures such as fern fronds and mountains. In other cases, the fingerprint of fractal geometry may be hiding in temporal structures, such as fluctuations in the stock market. Where else — and how else — might we need to look to discover fractals in natural phenomena that, at first glance, don’t seem to show any signs of exhibiting any aspects of self-similarity?
