Coastlines are fractals. Old news. But this news
story based on this paper in
Nature says that now we know why coastlines are fractals: because
that's the geometry that preserves the coastline, because it maximally damps the
force of the waves. In other words, coastlines are the products of evolution.
The coast line that is most likely to be preserved is that which is most
effective at damping the erosive nature of waves, and that's a fractal.
