The (Mis)behaviour of Markets

I never knew Benoit Mandlebrot had such a broad and interesting career - I just knew him from fractals and chaos theory.
In this book he gives a more mathematical depth to the concepts in Taleb's Black Swan. Fundamentally that modern financial instruments are based on a fallacy that the probability distribution of events is normal or gaussian. Real life isn't like that the unexpected is far more common than we like to think (as events in 2008 have confirmed)
