Abstract: Financial markets are complex systems, where crises of large fluctuations with high risks take place more than often. However, classical economics is unable to handle these situations. From a complexity 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 framework of computational experimental finance based on the microscopic modeling of markets. We argue that finance should be rebuilt resorting to a phenomenology framework, and econophysics will play a crucial role in this scientific revolution of economics.
