Abstract
Active systems defy the laws of equilibrium statistical mechanics, often enjoying long-range order in situations where dead matter cannot, as required by rigorous results. These strong, long range correlations result in a preternatural sensitivity to sample boundaries and boundary conditions. This Colloquium demonstrates this phenomena by focussing on a simple model of dry scalar active matter that demonstrates the salient effects without the additional complexity of hydrodynamics.
