This document discusses fractals and chaos theory. It begins by defining fractals as shapes made of parts that are copies of the whole, with theoretically infinite detail and self-similarity regardless of scale. Examples given include the Sierpinski gasket, Koch curve, and fractal trees. Fractals can have infinite perimeter but finite area. The concept of fractal dimensions is introduced, where fractal objects have non-integer dimensions. Chaos games and the Mandelbrot set are discussed as examples of chaos theory and fractals found in nature. Benoit Mandelbrot is credited with bringing fractals and their ability to model irregular natural forms to the mainstream.
71. Clouds are not spheres, mountains are not
cones, coastlines are not circles, and bark
is not smooth, nor does lightning travel in a
straight line... Nature exhibits not simply a
higher degree but an altogether different
level of complexity.
