Fractal
An object or quantity which displays Self-Similarity, in a somewhat technical sense, on all scales. The objectneed not exhibit exactly the same structure at all scales, but the same ``type'' of structures must appear on allscales. A plot of the quantity on a log-log graph versus scale then gives a straight line, whose slope is said to be theFractal Dimension. The prototypical example for a fractal is the length of a coastline measured with differentlength Rulers. The shorter the Ruler, the longer the length measured, a Paradox known as theCoastline Paradox.
