Workshop and Minicourse
"Conceptual Aspects of Turbulence: Mean Fields vs. Fluctuations"
11-15 February 2008

This workshop brings together a number of researchers working on turbulence in fluids, MHD, and plasmas. As implied by the title, the goal of the workshop is to discuss the interaction between regular and fluctuating, large- and small-scale components in turbulent systems and to attempt to understand how - conceptually and practically - one might to attempt to break beyond traditional approaches and make progress in understanding turbulence in space, on Earth, in the laboratory, in the computer or on paper.
