Simulation and Prediction in Complex Systems The Good the Bad and the Awful--

Leo Kadanoff, President of the American Physical Society, Department of Physics, University of Chicago,

Worthwhile computer simulations are done to explore uncharted territory, resolve a well-posed scientific or technical question, or to make a design choice. Some excellent work is reviewed Some less happy stories are recounted. I then concentrate my attention upon astrophysical simulations, showing how they can explore possible scenarios for stellar explosions.
