“Just saying that a structure is fractal doesn’t bring you any closer to understanding how it forms. There is an unique fractal-forming process, nor a uniquely fractal kind of pattern. The fractal dimension can be a useful measure for classifying self-similar structures, but does not necessarily represent a magic key to deeper understanding” (Ball, 2001, p. 117)

smaller surfaces have a larger heat exchange capacity, thus cool quicker and absorb less heat.
