In Introduction to Modern Dynamics, David D. Nolte ... provides us with a textbook for an alternative, and in many ways a more up-to-date, version of the classical mechanics course. Robert C. Hilborn, American Journal of Physics Introduction to Modern Dynamics strikes me as two books in one: a beginning graduate-level modern analyticalmechanics text emphasizing geometric techniques and a survey for advanced undergraduates of some current topics in the dynamics of complex systems. The bifurcation is an understandable consequence of the need to accommodate the perhaps outdated dictates of the traditional advanced undergraduate mechanics course. Noltes book is a bold attempt toward updating and energizing the physics curriculum. David Feldman, Physics Today Physicists in the twenty-first century will surely be called upon to address the many complex problems facing society using methods formulated in the nineteenth-century but enhanced by the powerful computers that are now ubiquitous. This book lays the groundwork for that undertaking and covers topics that should be part of the training of every undergraduate physics major Julien Clinton Sprott, author of Chaos and Time-Series Analysis
