Why have scientists, engineers, and mathematicians become intrigued by chaos? Chaos is about predictability in even the most unstable systems, and symmetry is a pattern of predictability - a conceptual tool to help understand complex behaviour. The Symmetry of Chaos treats this interplay between chaos and symmetry. This graduate textbook in physics, applied mathematics, engineering, fluid dynamics, and chemistry is full of exciting new material, illustrated by hundreds of figures. Nonlinear dynamics and chaos are relatively young fields, an in addition to serving textbook markets, there is a strong interest among researchers in new results in the field.

Written in the 1980s by one of the fathers of chaos theory, Otto E. Rössler, the manuscript presented in this volume eventually never got published. Almost 40 years later, it remains astonishingly at the forefront of knowledge about chaos theory and many of the examples discussed have never been published elsewhere. The manuscript has now been edited by Christophe Letellier - involved in chaos theory for almost three decades himself, as well as being active in the history of sciences - with a minimum of changes to the original text.Finally released for the benefit of specialists and non-specialists alike, this book is equally interesting from the historical and the scientific points of view: an unconventionally modern approach to chaos theory, it can be read as a classic introduction and short monograph as well as a collection of original insights into advanced topics from this field.

This book is devoted to the history of chaos theory, from celestial mechanics (three-body problem) to electronics and meteorology. Many illustrative examples of chaotic behaviors exist in various contexts found in nature (chemistry, astrophysics, biomedicine). This book includes the most popular systems from chaos theory (Lorenz, Rössler, van der Pol, Duffing, logistic map, Lozi map, Hénon map etc.) and introduces many other systems, some of them very rarely discussed in textbooks as well as in scientific papers. The contents are formulated with an original approach as compared to other books on chaos theory.

This book traces how key figures came to study chaos theory during the 1970s and 1980s, offering a collection of personal accounts that reveal the lesser-known stories behind a scientific revolution. Contributors were invited to share how they first encountered chaos, who introduced them to it, and what drew them to this then-unconventional field. They were encouraged to reference the works that shaped their journeys, providing insight into the often-surprising paths that led to major discoveries.With no strict stylistic constraints, each chapter reflects the individuality of the scientists, while also revealing common threads and influences that shaped the development of chaos theory. Together, these recollections offer a rare glimpse into the scientific atmosphere of the time — an era marked by curiosity, collaboration, and the rise of personal computing.Many pivotal contributions are discussed, and the book includes rare archival materials such as photos and letters. Highlights include a 1958 group photo from Hayashi's lab in Japan, and the first English translation of a significant Russian paper by Stepan Pulkin, whose daughter, a mathematician, contributed both the translation and personal insights.This book is both a historical document and a tribute to the people behind the equations — a unique opportunity to witness the birth of chaos theory through the eyes of those who lived it.
