Unlike bird flocks, whose motion in the sky cares little about boundaries, most active systems exist within confined spaces. For example, the cytoskeleton is bounded by the cell membrane, and the motion of cells within an organism in constrained by neighboring tissues. Such confinement, it turns out, can have profound effects, and those effects are very sensitive to the geometry of the boundaries. In this talk I will discuss how the response of active systems to the geometry of their confinement arises from the dynamics of their active constituents along the boundaries and how to relate the dynamics along the boundaries to the macroscopic properties of the system (e.g., density, pressure).
