Course begins with an exploration of chaos and complex systems theory as an antidote to the equilibrium thinking most students have been taught. This includes the logistic model as a basic definition of chaos theory, and complex systems models self-organized criticality, Bak-Sneppen ecosystem, network theory, attractors, hysteresis, and bistable systems (many accompanied by computer-based experiments). The remaining two third of the semester is devoted to understanding and explaining the behavior of Earth systems and human societies in terms of the non-equilibrium universality properties of chaos/complex systems.
