  Fractal - Wikipedia, the free encyclopedia
The term fractal was coined in 1975 by BenoƮt Mandelbrot, from the Latin fractus or "broken".
Fractal geometry is the branch of mathematics which studies the properties and behaviour of fractals.
Fractal geometry was also used for data compression and for modelling complex organic and geological systems, for example the growth of trees or the development of river basins.

Fractals are generally irregular (not smooth) in shape, and thus are not objects definable by traditional geometry.
Some common examples of fractals include the Mandelbrot set, Lyapunov fractal, Cantor set, Sierpinski gasket and carpet, Menger sponge, dragon curve, Peano curve, and the Koch curve.
These naturally occurring fractals (like clouds, mountains, river networks, and systems of blood vessels) have both lower and upper cut-offs, but they are separated by several orders of magnitude.

The term fractal is now used as a scientific concept, as well as a strictly mathematical idea.
Fractals such as the Mandelbrot set are more loosely self-similar: they contain small copies of the entire fractal in distorted and degenerate forms.
Fractal techniques have also been employed in image compression, as well as a variety of scientific disciplines.

 Fractal   (Site not responding. Last check: 2007-11-06)
In many cases a fractal can be generated (for example on a computer screen) by a repeating pattern, typically a recursive or iterative process.
Fractals of many kinds were originally studied as mathematical objects, and the term "fractal" has been given various precise definitions by mathematicians.
Fractal geometry rescues this situation by providing new tools which are able to accommodate this detail.

 sci.fractals FAQ
Fractals also describe many real-world objects, such as clouds, mountains, turbulence, coastlines, roots, branches of trees, blood vesels, and lungs of animals, that do not correspond to simple geometric shapes.
Roughly, fractal dimension can be calculated by taking the limit of the quotient of the log change in object size and the log change in measurement scale, as the measurement scale approaches zero.
Topics include: challenges of using fractals in the classroom, new ways of generating art and music, the use of fractals in clothing fashions of the future, fractal holograms, fractals in medicine, fractals in boardrooms of the future, fractals in chess.

 Extracting beauty from chaos
Like most fractal images, Lyapunov Exponent fractals are produced by iterating functions and observing the chaotic behaviour that may result.
Alexander M. Lyapunov, 1857-1918) is used to measure the extent to which ever-smaller "infinitesimal" errors are amplified.
The Lyapunov Exponent is defined to be the limiting value of the above quantity as the initial error E[0] is made ever smaller-and-smaller, and the number of iterations n is sent to infinity.
