SUMMARY:Small-numbers dynamics in biology and nanotech: the Maximum Caliber
	 approach to nonequilibrium statistical mechanics
DESCRIPTION:Featuring Ken Dill\, University of California at San Francisco\
	nHosted by: William Klein\nPoster: http://physics.bu.edu/internal//posters/
	2008_Fall/02_Dill.pdf\n\nPart of the Physics Department Colloquia Series.\n
	\nAbstract:  The laws of dynamics — Fick’s law of diffusion\, Fourierâ€
	™s law of heat flow\, and the mass-action models of biochemistry\, for exam
	ple — are applicable in bulk solutions where the numbers of particles are
	 macroscopically large.  But\, inside biological cells\, or in applications
	 in nanotechnology\, the numbers of particles of a given type is often less
	 than a few hundred.  We are interested in the dynamical fluctuations that 
	occur in such cases.  To explore small-numbers dynamics\, we have explored 
	small-numbers diffusion by microfluidics and single-particle two-state chem
	istry using laser-trap experiments.  We find that the dynamical distributio
	ns are well predicted by a trajectory-based approach that ET Jaynes called 
	"Maximum Caliber".
