Wilson's Renormalization Group Theory

Wilson's Renormalization Group Theory is a framework in physics that explains how systems behave at different scales, especially near critical points like phase transitions. It involves gradually zooming out—averaging or "coarse-graining" tiny details—to see larger patterns emerge. This process reveals how fundamental interactions change with scale, helping scientists understand universal behaviors across diverse systems. Essentially, it’s a method to study how the laws of physics remain consistent or transform when viewed from different perspectives or levels of detail.
