'This book contains information that will benefit both students and researchers in many areas of physics, mathematics and other sciences who are working on problems in chaos, statistical mechanics, spatial patterns, symmetries, etc.' Contemporary Physics The serious student of chaos will find this book well worth reading. As a technical review, it is presently unparalleled, and as a provocative introduction to the mysteries of patterns, it is unique. Ronald F. Fox, American Journal of Physics ...will be of most interest to specialists looking for a source for this material outside the original literature - the only other place much of it can be found. C. Eugene Wayne, Physics Today The material in this book can, and should, be incorporated into a senior undergraduate, or first year graduate, mechanics course. This is also an interesting and very readable book for physicists and applied mathematicians who are interested in chaos, irreversibility, and theories of spatial patterns and symmetries. I recommend this book highly.... K.K. Lee, Physics in Canada a stimulating book that can provide new ideas on the generation and occurrence of patterns is a wide range of situations. Peter J. Bryant, SIAM Review
