Fractal Curve
Construction of the Gosper curve

A fractal curve is, loosely, a mathematical curve whose shape retains the same general pattern of irregularity, regardless of how high it is magnified, that is, its graph takes the form of a fractal.[1] In general, fractal curves are nowhere rectifiable curves -- that is, they do not have finite length -- and every subarc longer than a single point has infinite length.[2]

An extremely famous example is the boundary of the Mandelbrot set.

Fractal curves in nature

Fractal curves and fractal patterns are widespread, in nature, found in such places as broccoli, snowflakes, feet of geckos, frost crystals, and lightning bolts.[3][4][5][6]

See also Romanesco broccoli, dendrite crystal, trees, fractals, Hofstadter's butterfly, Lichtenberg figure, and self-organized criticality.

Dimensions of a fractal curve

Most of us are used to mathematical curves having dimension one, but as a general rule, fractal curves have different dimensions,[7] also see also fractal dimension and list of fractals by Hausdorff dimension.

Relationships of fractal curves to other fields

Starting in the 1950s Benoit Mandelbrot and others have studied self-similarity of fractal curves, and have applied theory of fractals to modelling natural phenomena. Self-similarity occurs, and analysis of these patterns has found fractal curves in such diverse fields as

  1. economics,
  2. fluid mechanics,
  3. geomorphology
  4. human physiology, and,
  5. linguistics.

As examples, "landscapes" revealed by microscopic views of surfaces in connection with Brownian motion, vascular networks, and shapes of polymer molecules all relate to fractal curves.[1]
