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.

- 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.
