a related way to view this effect is through fractal geometry.As the boundary of a patch changes from a smooth line to a complexly folded configuration,the fractal dimension,D ,increases.At low values of D,p(ek), which is already close to unity. the relationship between p(ek) and D shown in figure 2.16 is speculative,but it represents a start in formulating hypotheses relating these factors. Theoretical explorations of this relationship might prove rewarding
