There are several java applications you can run from this page. They are
all prototypes -- without an interactive user interface!
There are three chaos applets:
One applet runs
the Henon map with parameters set that make it a Hamiltonian system:
Hamiltonian Henon
Another applet runs the Henon map with parameters set that make it a
dissipative system:
Dissipative Henon
Both programs scan through different values of a control parameter "a",
so the pictures will evolve as you watch. The programs will run quickly
or slowly depending on the speed of your computer. Hit the back button
to exit the java program and get back to this screen.
I've also added a Julia set applet, which is _slow_, so be patient as it draws the
map
Julia Set
The last applet was written to demonstrate the random motion of
molecules in a box. The molecules, colored spheres, bounce around and
explore the confines of the box. At fixed times the applet pauses and
counts the number of molecules on the left side of the box and the right
side of the box. For small numbers of molecules, the probability of being
on the left or right has large deviations from 50%. As the number of
molecules is increased, these deviations would become smaller.
Box Model of Gas
There is a bit of flicker as the molecules are redrawn that
I've not eliminated.
