Theoretical and Computational Chemistry
Theoretical problems in chemistry range from the quantum mechanics of electrons in individual chemical bonds to the collective behaviors of large molecules and new materials. There are connections to condensed matter physics, to the phenomena of life, to the design of new algorithms, and to more abstract problems of statistical and quantum mechanics. In a series of mini-symposia, we will explore this full range of questions.

Tuesday, 9 April 2013 - From molecular mechanisms to macroscopic dynamics in biological networks
The last decades have seen an explosion of tools for characterizing the microscopic mechanisms at work in biological systems. But many of the most interesting phenomena of life operate at more macroscopic levels—the fates of cells in a developing embryo, the organized motions of cytoplasm, the states of neural networks that represent thoughts or actions, and much more. There is a long history of trying to link microscopic and macroscopic through dynamical and statistical models, as in the physics of inanimate systems. These theoretical efforts highlight two key ideas. First, many of the microscopic parameters disappear from our macroscopic description, yet some molecular details are strikingly important. Second, we want to explain behavior without appeal to implausibly fine tuning, yet many real biological systems are described by very special points in the parameter space of possible models. In this symposium we will explore these issues as they appear in systems ranging from single cells to the brain. We hope that the schedule will allow for considerable discussion.
