摘要：
I discuss various aspects of the role of the conformal anomaly number c in two-and one + one-dimensional critical behaviour: its appearance as the analogue of Stefan's constant, its fundamental role in conformal field theory, in the classification of 2d universality classes, and as a measure of quantum entanglement, among other topics.
