www.physics.drexel.eduThe renormalization group itself allows one to solve systems where uctu-ations on a wide range of length scales are important, as is the case in critical phenomena. It is a method for accurately connecting the small scale varia-tions with larger and larger scales. The name follows from the renormalization procedure for Feynman diagrams.
