Mandelbrot Set
The Mandelbrot set was introduced in 1980, showing how complex phenomena
could be generated from simple rules iterated repeatedly. The Mandelbrot
set is formed by iterating z = z2
+ c for all values of c = x + i y, with
an initial value of z = 0. For different complex numbers c, many of the
points generated by iterating z2 +
c escape to infinity. Those that do not are in the Mandelbrot set.

Benoit Mandelbrot, often referred to as the father of fractals, almost
single-handedly created a new geometry of nature. This new mathematics,
with a physics base, has fundamentally altered our view of the universe.
It is based on the concept of using simple rules to generate complex
structures. According to Mandelbrot, fractals themselves "are
irregular geometric shapes
having identical structure at all scales." In his 1967 paper
"How long is the coast of Britain? Statistical self-similarity and
fractional dimensionally?" Mandelbrot identified the concept of
length as dependent upon the choice of measuring instrument. He introduced
the concept of fractal dimension by suggesting that the dimension of a
coastline, for example, must fall somewhere between the dimensions of a
smooth curve (with dimension one) and a smooth surface (with dimension two).
