The renormalization group (RG) is a mathematical and conceptual framework used in theoretical physics to study changes in a physical system as one looks at it at different scales. It is particularly prominent in quantum field theory, statistical mechanics, and condensed matter physics. The central idea behind the RG is that the properties of a system can change when one changes the scale at which one observes it.
