How about the use of fractals in science?
In order of increasing difficulty and decreasing use are applications
to (1) describe, (2) explain, (3) predict phenomena.
My expertise in the earth sciences.
Fractals as description: There have been many books that show how fractals
can describe natural phenomena such as landscapes, cracks in rocks,
earthquake aftershock distributions.
Fractals as explanation: The observed fractal distribution of fractures
in rock constrains explanations of causes these fractures.
The fractal pattern of aftershocks may be related to fractal nature of fractures.
Fractals as prediction: The probability of earthquake aftershocks decreases
in a fractal manner. This is waht you here from seismologists after a large
earthquake. Imicisble fluids can interfinger in a fractal manner. This helps
petroleum engineers understand how injection recovery methods will perform
and hydrologist how water and polutants flow in the earth. Geological layers
are fractal. Earth noise is fractal. This constrains time series analysis in
inverting seismic recordings for earth images.
