The software package includes a User's Manual for the PC computer. STARTING THE PROGRAM To start the program, type START and press . Alternatively, you may type CHAOS and press . OVERVIEW CHAOS DEMONSTRATIONS is a collection of twenty-six demonstrations illustrating chaos in physical and biological systems. The goal of the program is to encourage an appreciation of the complexity and beauty of even simple systems, not only for the professional scientist, but also for the interested nonspecialist. The demonstrations can be appreciated on many different levels, from the forefront of research in nonlinear dynamics to pure art. They can be used by an instructor in the classroom, by individual students as a tutorial, or as a display in a museum. You can sit back and watch the demonstrations cycle through an automatic sequence or take control and examine in detail the effect of varying the parameters. All the commands are by single keystrokes or single clicks of a mouse. The program is written to make it easy for you to move from one thing to another. It is accompanied by a graded multiple-choice quiz during which you may review the appropriate demonstration.
