3. 3 07/11/2008Applied Math at the DOEDavid L. Brown What kinds of questions can CS&E help answer for DOE? Can we predict the operating characteristics of a clean coal power plant? Answering these and other important questions involves study of increasingly complex physical and engineered systems How stable is the plasma containment in a Tokamak? How quickly is climate change occurring and what are the uncertainties in the predicted time scales? How quickly can the US recover if part of the power grid became inoperable? How can new materials be designed with a specified desirable set of properties?
