    check our most recent publications or contact us for more information Earth s carbon cycle Earth s carbon cycles through the atmosphere oceans living organisms and rocks How does the carbon cycle work The problem ostensibly falls at the intersection of earth science biology and chemistry However observations spanning a wide range of environments and biogeochemical transformations exhibit common features suggesting that simple physical mechanisms exert significant control We seek a fundamental understanding of these physical processes and explore their relevance to present and past environmental change Co evolution of life and the environment The geologic record suggests that major events in the history life nearly always occur concurrently with environmental change To understand how and why these changes occur we study the geochemical fossil and molecular records and relate them to environmental dynamics We are especially interested in the early oxygenation of the environment the evolution of multicellular life and mass extinctions Geometry of natural forms The natural world contains abundant examples of geometric organization We seek the mathematical expression of such forms and shapes and relate them to the physical mechanisms responsible for their formation A particularly rich set of problems occurs in the growth of valley and

    18352J Theoretical Environmental Analysis This undergraduate course provides students with an understanding of the mechanisms that underly the organization of the natural environment It also introduces students to methods of quantitative analysis that are useful for investigating how any system works The course teaches students how to identify fundamental phenomena how to formulate theoretical models and how to quantitatively test models by comparison to observations A secondary but no less important objective is to provide students with a unified view of environmental science by emphasizing aspects of earth atmospheric and planetary sciences that collectively act to create the natural environment both physical and biological Offered jointly by the Department of Earth Atmospheric and Planetary Sciences and the Department of Mathematics Past courses of note 12 006J 18 353J 2 050J Nonlinear Dynamics I Chaos This undergraduate course provides an introduction to the theory and phenomenology of nonlinear dynamics and chaos Offered first by the Department of Earth Atmospheric and Planetary Sciences in 1989 and later jointly with the Department of Mathematics and the Department of Mechanical Engineering The course continues to be taught by others and remains popular Course materials including detailed lecture notes are available through MIT s Open
