Computer simulations are now an integral part of contemporary basic and applied physics,
and computation has become as important as theory and experiment. The ability to compute
is now part of the essential repertoire of research scientists.
Since writing the first two editions of our text, more courses devoted to the study of
physics using computers have been introduced into the physics curriculum, and many more
traditional courses are incorporating numerical examples. We are gratified to see that our
text has helped shape these innovations. The purpose of our book includes the following:
1. To provide a means for students to Jo physics.
2. To give students an opportunity to gain a deeper understanding of the physics they
have learned in other courses.
3. To encourage students to "discover" physics in a way similar to how physicists learn
in the context of research.
4. To introduce numerical methods and new areas of physics that can be studied with
these methods.
5. To give examples of how physics can be applied in a much broader context than what
is discussed in the traditional physics undergraduate curriculum.
6. To teach object-oriented programming in the context of doing science.
