- Chaos and Fractals - ThinkQuest 1996
Chaos is an advanced field of mathematics that involves the study of dynamical systems or systems in motion. Chaos Theory consists of the mathematical proofs and theories that attempt to describe processes in motion. Think of any
mathematical system that changes over time, such as the weather, the stock market, or the genetic distribution of a population. Tour of Chaos: Basic Concepts (Iteration, Orbits, Attraction and Repulsion, Graphical Analysis, Bifurcations); Examples (Cantor Set, Sierpenski Triangle, Mandelbrot Set, Julia Set); Java Applets Involving Chaos (Mandelbrot/Julia Set Explorer, Mandelbrot Escape Sequences).

Generate random numbers on the Internet by using a web form (comparable to throwing dice), randomized sequences (lottery tickets), raw random bytes, virtual coin flips, or bitmaps. All numbers are tested statistically and the results available in real-time. Read the introduction to randomness, random numbers, and how random.org generates random numbers. Source code available.
