Dynamics of Complex Systems
12.517 G(2) 3­0­9 Spring 2003

The theme for Spring 2003 will be
Evolution of Biogeochemical Cycles.

This term we will focus on the dynamics of long-term biogeochemical cycles. Emphasis will be on the development of theories to explain and interpret observed variations in the geologic record. The class will be composed of pedagogical lectures and roundtable discussions of classical works and recent literature.

We will meet twice weekly. No background in earth science will be presumed; however mathematics at the level of 18.03 is essential.

Schedule: Mondays and Wednesdays from 3:00-4:30 in Rm. 54-313.

Instructor: Prof. Daniel Rothman
