The COMPLETE summer school on Small-Scale Turbulence in Clouds was hosted by Max Planck Institute for Dynamics and Self-Organization in Göttingen. MPIDS is engaged in a variety of dynamical and in particular self-organizational phenomena: from vortices in turbulent flows, and neural networks in the brain, to granular matter and complex fluids. Although these systems can be assigned to different disciplines, they often follow similar laws and can thus be studied and described using similar methods.
