Chaotic Dynamics: An Introduction

Books that take you from undergraduate physics to a nontrivial understanding of nonlinear dynamics, chaos and fractals are rare. Chaotic Dynamics does the job ellegantly. The familiar pendulum is used to illustrate the basic techniques and concepts in nonlinear dynamics. The reader is gently introduced to phase diagrams, Poincare sections, basins of attraction and bifurcation diagrams. Computer code is included in the Appendix. The interested reader can use this code to further illustrate the lessons of the text or to embark on his/her own exploration of the pendulum and other dynamical systems. Having used the pendulum to establish a firm conceptual platform, Baker and Gollub progress gracefully into the logistic map to illustrate concepts such as period doubling, Lyapunov exponent, entropy, stretching and folding, and various measures of fractal dimension. The presentation is nicely rounded off with studies of other maps and nonlinear dynamical systems from a range of fields in physics, chemistry and fluid dynamics.
