Fractals, a term coined by their originator Benoit Mandelbrot, are objects of any kind whose spatial form is nowhere smooth (i.e., they are irregular) and whose irregularity repeats itself geometrically across many scales. The irregularity of form is similar from scale to scale, and the objects are said to possess the property of self-similarity or scale invariance. [Source: Encyclopedia of Human Geography; Fractal]
