Chaos theory is not just of interest to the physical sciences. Davies (mathematics, Australian National U.) introduces the theory of chaos (including fractals) in non-linear dynamic systems coupled with numerical and graphical representation, without resorting to advanced calculus and algebra. Appendices provide documentation for Chaos for Java software, a discussion of computing various types of equations, and a list of dimensional maps. Annotation c.
