Abstract:

Apr2 ColloqMany problems involving the large deformations of soft extended objects such as strings and membranes can be formulated using elementary geometry and physics. I will discuss some of the general and specific features of these problems and their role in the description of patterns on many different length scales in the material world ranging from the deformation of atomically thin nanotubes, the self-similar wrinkles in skin, the aesthetic drapes of a fabric, the intricate folds in origami, the violently crumpled sheet that is the fate of many a calculation gone awry, and the morphology of tectonic subduction zones.
