CHAOTIC DYNAMICAL SYSTEMS
A presentation by Victor J. Donnay, Associate Professor of Mathematics, Bryn Mawr College, and students and colleagues at the College
In Dynamical Systems, an object moves according to a rule. Depending on the
rule motion, the object may move in a regular fashion or in a chaotic
fashion. We illustrate the ideas of chaos theory by letting the user play
with three different types of dynamical systems:
1. Billiards in which a ball moves around inside a billiard table.
The user can choose different shapes for the table (polygon, circle,
ellipse, stadium). For some shapes, the billiard motion is regular; for
others it is chaotic.
2. The Phase Space Game in which a point hops around inside a
rectangle. The moving point produces beautiful colored patterns. The user
can vary the rules of motion to produce either a regular pattern, a
chaotic pattern or a pattern that has a mixture of regular and chaotic
3. Iteration of a point on the real number line. A point moves on
the number line according to various rules that the user chooses. One can
display the motion either numerically or using the staircase method.
