From the reviews: "This excellent book should certainly find a good place in every library of research centres in astronomy and cosmology." (Physicalia, 25/3, 2003) "There is plenty of interesting and useful information in the book. [...] I was always puzzled as to why Lyapunov exponents of chaotic orbits take so long to ... Read moreconverge, and now I understand." (Prasenjit Saha, Physics Today, Nov. 2003) "This book is the first to provide a general overview of order and chaos in this field of research.[…] This book, addressing especially astrophysicists, can also be used as a textbook on dynamical systems and astronomy for students in physics." (Zentralblatt MATH 2004, vol. 1041, page 69) "This book represents a collection of the experience accumulated by Contopoulos in about 50 years of activity. … Researchers in dynamical systems and in astronomy and astrophysics will find in this book excellent source of information … . Advanced students working in dynamical systems may use it as a complete textbook … . Students in dynamical astronomy will appreciate in particular the two sections devoted to the dynamics of galaxies and to other astronomical applications." (A. Giorgilli, Mathematical Reviews, 2004 f) "The study of orbits in nonlinear dynamical systems has progressed enormously over the last decades and thus became an important tool in dynamical astronomy. … This book is the first to provide a general overview of order and chaos in this field of research. … Quite useful and interesting is a list of more than seventy open problems … . This book, addressing especially astrophysicists, can also be used as a text book on dynamical systems and astronomy for students in physics." (Klaus Brod, Zentralblatt MATH, Vol. 1041 (16), 2004) "The author is a well-known scientist who has been involved in research in Dynamical Astronomy and Dynamics of galaxies for the last 50 years. … The amount of work done isimpressive, and the present Volume can be considered as a summary of ideas and numerical results obtained by the authors and collaborators. … The book can be interesting as a source of information for the heuristic discussions following the presentation of several concrete problems in Astronomy." (Carles Simó, SIAM DS Web, January, 2004) "If you are charmed by the order-chaos dichotomy, you will find much to enjoy in the book. … George Contopoulos has a half-century record of working on unusual but interesting problems. … It is interesting to have a pioneer’s view. … there is plenty of interesting and useful information in the book. … I was always puzzled as to why Lyapunov exponents of chaotic orbits take so long to converge, and now I understand." (Prasenjit Sinha, Physics Today, November, 2003) "This large monograph, more than 600 pages, is devoted to the modern approach of dynamical astronomy. … The author, who has largely contributed to the dynamical astronomy, gives here a complete panorama of this domain in a clear and modern presentation. Mathematical concepts of the theory are nicely presented with more than 350 figures in view to make things understandable. … This excellent book should certainly find a good place in every library of research centre in astronomy and cosmology." (Stéphane Métens, Physicalia, Vol. 25 (3), 2003) "This comprehensive book covers many important topics of dynamical systems with application to the contemporary understanding of stellar and galaxy structure and evolution. … It should be regarded as not only a good introduction to the complicated field of dynamical astronomy, but also as a handbook for many people working in different branches of contemporary physics and astrophysics. It, therefore, will be useful for many professionals and especially postgraduate university students … as well as for those specialized in mechanics and general dynamics." (A. M. Fridman and M. Ya.
