Moving on from his books on chaos ("Does God Play Dice?") and symmetry ("Fearful Symmetry"), the author of this book deals with the wider field of complexity theory. The book tackles the question of how complexity arises in nature, of how life overcomes chaos and entropy to create developing order. Co-written with biologist Jack Cohen, the book will range across the central areas of modern science, from quantum mechanics and cosmology to evolution and intelligence, looking at the central questions of order, chaos, reductionism and complexity.
