Mpeg movies of chaos and complexity

• Spiral (2.5 megs) defect chaos in Rayleigh-Benard convection from Stephen Morris at the University of Toronto.
• Two mpegs of laser beam's bouncing around in sodium vapor from Reto Holzner's Nonlinear Optics and Nonlinear Dynamics group at the University of Zurich. Yes, Virgina, photons can bounce off of one another (in a suitable bath): beam bouncing film 1, beam bouncing film 2.
• A series of movies showing pattern formation in capillary ripples. This is a very simple experiment. Take a container of water and shake it up and down (about 300 HZ in this movie). Now shine light through the bottom of the clear container, and an image of the top surface of the water will be formed by the light passing through the water/air interface. The patterns formed at the surface are capillary ripples (surface waves whose structure is dominated by the surface tension or "capillary" forces). Now we study the patterns that appear as the amplitude of the forcing is increased. It is observed that standing waves forming a square lattice form at lower amplitudes, and this patterns breaks up (melts) and becomes time dependent at higher forcing amplitudes. For more information see: N. B. Tufillaro, R. Ramshankar, and J. P. Gollub, Order-disorder transition in capillary ripples, Physical Review Letters 62 (4), 422 (1989). ripple film 0, ripple film 1, ripple film 2, ripple film 3, ripple film 4, ripple film 5, ripple film 6, ripple film 7, ripple film 8.
• Here are some movies providing a three-dimensional view of the strange attractor that is constructed from experimental data from the string experiment by Molteno and Tufillaro. The movies where made with the string program by Pete Wyckoff that runs on the SGI: string film 0, string film 1, string film 2, string film 3, string film 4,
• Some movies showing the use of KL tool in the analysis of data from a rotating convection experiment from Li Ning and Bob Ecke: convection film 1, convection film 2, convection film 3.
