From the reviews: "This book is a collection, from the last 40 years, of the most influential papers in the development of chaos theory. ... The editors are eminent in this field ... . Their selection of papers is excellent ... . it is a book for mathematics graduates specializing in non-linear dynamics. ... is a well-presented and well-deserved tribute to the life's work of Professor Yorke ... . might well be as that benchmark that mathematicians of the future will view its publication hundreds of years from now."
