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dynamics of complex systems‎.‎ The bifurcation is an understandable consequence of the need to accommodate the perhaps outdated dictates of the traditional advanced undergraduate mechanics course‎.‎ Noltes book is a bold attempt toward updating and energizing the physics curriculum‎.‎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
