An interesting and important event next week at Weitzman Institute of Science in Israel. The workshop organized by Dr. Eran Bouchbinder will focus on the dynamics of spatially-extended frictional interfaces. A significant fraction of the meeting will be devoted to open discussions that will focus on outstanding problems in the field (frictional instabilities, nucleation, super-shear rupture, bi-material interfaces, finite-size effects, lubricated interfaces).
