How ever, classical economics is unable to handle these situations. rom a complex- ity science perspective, we present a picture of the evolution and burst of financial bubbles for the current financial tsunami based on the macroscopic modeling of financial markets. We further introduce a fram e- w ork of computational experimental finance based on the microscopic modeling of markets. We argue that finance should be rebuilt resorting to a phenomenology fram ework, and econophysics will play a crucial role in this scientific revolution of economics.
