Describes the theory of self-organised criticality, an extension of complexity and chaos theories. Bak presents an accessible general theory of complexity which can help to understand nature, and can be applied to any complex system from weather to avalanches. `This book is essential reading for those interested in complex systems in general', Philip Anderson, Nature.
