Euclidean Geometry seems to be irrelevant when trying to describe complex geometrical shapes found in nature.
Fractal geometry is a new form of mathematics used to describe objects having self-similarity.
In this talk, two aspects of fractals are presented. The first is Random Iteration Algorithms for producing fractal patterns such as the fern or the Mandelbrot Set. The second is the calculation of dimensions of fractal objects such as the Sierpinski gasket or the Von Koch curve . The latter is used as a model for a coastline whose raggedness is to be determined.
