Explore New Dimensions with Versatile Chaos Mapping Tool

Physics Academic Software Releases CHAOTIC MAPPER

December 20, 1993--CHAOTIC MAPPER is an exploratory tool that allows for
the examination of chaotic systems and fractal structures. Developed by
James B. Harold of the University of Maryland, the program can be used for
demonstration, but was designed as an aid for guided or independent study.
It encourages exploration of chaotic systems at a self-directed pace and
offers the flexibility to discover interesting new parameter regions and
behaviors.

There are 22 different one- and two-dimensional iterative maps and
three-dimensional differential equations. Depending on the map selected,
users can examine parameter phase space plots, two-dimensional plots,
convergence maps, Poincare sections, basins of attraction, or the behavior
of a group of points. Graphing modes are upward compatible:
two-dimensional systems may be projected into one dimension, and
three-dimensional systems may be reduced to two dimensions using a
Poincare section.

"As a field of study, chaos may be approached from many levels, from simple
iterative maps to complex differential equation systems," says Harold.
"Because of this advantage, and the flexibility of CHAOTIC MAPPER, the
program can be used in a variety of classroom situations." Students may be
given specific tasks to perform as homework or small projects. This could
include identifying attractors or confirming the scaling behavior of a
bifurcation cascade. Or they may be asked to perform an in-depth
investigation of a system, such as the forced, damped pendulum, as a term
project.

New equation systems can be entered and saved to disk for later retrieval.
And once generated, images can also be stored and recalled individually,
as a slide show, or as an animated picture. The program provides full
control over the graphing environment, including zoom feature and color
and palette control. For demonstration purposes, you can store program
configurations and defaults to disk in order to make classroom use
easier.

Reviewers are excited about CHAOTIC MAPPER. Phil Gash, California State
University, Chico, calls it "a comprehensive research and learning tool
that is ideal for investigators exploring chaotic problems requiring one-
and two-dimensional maps." "Excellent software," says Kailish Chandra,
Savannah State College. "Every undergraduate physics department should
make it available to students. And noted chaos software author Julien C.
Sprott, University of Wisconsin, Madison, notes that the "good graphics
and modern user interface allow for detailed exploration of many standard
chaotic systems as well as ones defined by the user.

CHAOTIC MAPPER is published and distributed by Physics Academic Software,
which is a project of the American Institute of Physics in cooperation
with the American Physical Society and the American Association of Physics
Teachers, as part of a continuing series of educational software from
PAS.

CHAOTIC MAPPER operates on PC computers with at least 512K of RAM memory,
DOS 3.3 or higher, and Hercules, CGA, MCGA, EGA, or VGA color graphics. A
math coprocessor, a mouse, and a printer with graphics capability are
highly recommended.

CHAOTIC MAPPER may be purchased from Physics Academic Software for $69.95
plus $3.50 shipping and handling for the first package ($12.50 foreign air
mail) and $.75 ($4.00 foreign) for each additional package. Lab Packs,
which include ten copies of the software and one User's Manual, are
available for $209.95.

For a limited time, you can purchase the entire PAS collection, with or
without Lab Packs, and save up to 20% off the regular price. Physics
Academic Software offers a no-risk guarantee by providing a full refund
for packages returned within 30 days.

PAS also offers a Standing Order Plan, which brings the latest in
innovative physics courseware to your door, along with exceptional
savings. When you join the Standing Order Plan, you will automatically
receive each new PAS program, with or without Lab Packs, and save up to
20% off the list price.
