Kenneth G. Wilson

Work Wilson's work in physics involved formulation of a comprehensive theory of scaling: how fundamental properties and forces of a system vary depending on the scale over which they are measured. He devised a universal "divide-and-conquer" strategy for calculating how phase transitions occur, by considering each scale separately and then abstracting the connection between contiguous ones, in a novel appreciation of renormalization group theory. This provided profound insights into the field of critical phenomena and phase transitions in statistical physics enabling precise calculations. One example of an important problem in solid-state physics he solved using renormalization is in quantitatively describing the Kondo effect.

He extended these insights on scaling to answer fundamental questions on the nature of quantum field theory and the operator product expansion and the physical meaning of the renormalization group.

He also pioneered the understanding of the confinement of quarks inside hadrons, utilizing lattice gauge theory, and initiating an approach permitting formerly foreboding strong-coupling calculations on computers. On such a lattice, he further shed light on chiral symmetry, a crucial feature of elementary particle interactions.
