A visit to a bookstore is generally a good idea. I say generally because I started reading the book on Black Swan written by Nassim Nicholas Taleb and it has distracted me from some serious work. Taleb has an interesting theory as to attributing everything to the chance. Well one cannot argue much with such theories but the question that I could not resist is, so what? 

In the world of complexity,there are obviously several


many variables. However, as a physicist I think of understanding the universe in much complex phenomena into simple elegant natural principles. Obviously understand such complexity with some physical principle gives us predicitive power. 

Where I agree with Taleb is the black swan idea is as good when it applies to human domains such as stock market, wars and climate.  David Hume called it problem of induction.  However, using history as a guide I can confidently say that the seeming nonlinear randomness there is a more fundamental principle that governs the nature of the universe.
