Physics of Community: The Modeling of Decision Making Processes

We use concepts from chemical engineering to model decision making processes in education, politics, finance, and other social arenas. Ideas and decision making processes can be represented in ways analogous to molecules and process flow diagrams, connected by continuum equations. The science of decision making then begins to have interesting analogies to the processes of physics, chemistry … and biology. We combine ideas from game theory and information sciences with concepts of chemical engineering modeling to examine particular social problems.
