"The Pendulum: A Case Study in Physics" describes one physical system - the pendulum - and its manifestations in classical and modern physics. While being a technical work, this remarkable study is set within the context of the technological, historical, and cultural developments to which the pendulum has contributed. In this well-illustrated treatment of the study of pendulum, Baker (Bryn Athyn College of the New Church) and Blackburn (Wilfrid Laurier U.) provide fascinating information about the history of the pendulum and what scientists thought it did, the revolution wrought by Foucault, the special cases of the torsion pendulum, the chaotic pendulum, the quantum pendulum, and coupled pendulums, the effects of superconductivity, and the most familiar to most of us, the pendulum clock. They include information on special interests in the appendices, such as the inverted pedulum and the longnow clock. SciTech Book News, December 2005.
