Mandelbrot is an odd character, but a superb thinker. His book does not offer a lot of science, but rather a compelling view of how this fascinating and growing topic developed. I recommend it highly.It's OK but.... Benoît Mandelbrot is unquestionably a great savant but he should have taken some lessons on how to write books. There is an intense feeling of disappointment after reading this book and it is hard to pinpoint why. It's all there: nature in a wondrous new light. An original work which almost singlehandedly (well... almost) spawned a new field, a field which is not only beautiful but immensely useful as well. The discourse is not too complicated and it is not simplistic pap-science either. Yet there is something missing, a passion or what some might call 'heart'. When I pick up a book about fractals, even when it is a highly technical work like formal fractal geometry, there is always a certain sense of excitement, of dabbling with a new and beautiful toy. You won't get that feeling with this book. I still recommend it, in fact I think that it is a must-have if you are serious about this topic, but don't expect too much excitement.
