How does one exactly illustrate the principle of chaos? Well, fortunately for budding physicists and other interested parties, a very nice animation demonstrating chaos (and other such processes and phenomena) are made available at this website. Created by David M. Harrison of the Department of Physics at the University of Toronto, the site contains Flash animations that illustrate principles in such categories as optics, sound waves, vectors, and relativity. Visitors are welcome to click on each category, or to scroll down to the specific processes such as the Lorenz Attractor or such principles from classical mechanics as displacement and distance. It is worth noting that the animations are also available in Catalan and Spanish.
