Take air pressure,for example.The familiar isobars on weather chartsdefine regions of equal pressure,similar to the elevation contours ona map.Indeed,an isobar can be thought of as a kind of "coastline",described by its own fractal law.But there’s a key difference:acoastline’s shape is defined only at one specific value of height – sealevel.In contrast,the isobars of air pressure form a whole array ofshapes at different heights,like Russian dolls nested within eachother.Air pressure is what mathematicians call a multifractal field,described by a whole set of power laws,rather than just one.
