Abstract: Conformal symmetry generalizes scale invariance, the hallmark of continuous phase transitions. The additional symmetry highly constrains correlation functions and imposes an infinite set of ``crossing'' relations between them. It has now become possible to calculate scaling dimensions, critical exponents, and other quantities by exploiting crossing symmetry. This bootstrap program has in some cases provided accurate predictions for critical phenomena. This review provides a state of the art picture of this program.
