Abstract: Although he got a Nobel prize in solving a condensed matter problem, Ken Wilson’s contribution to solving strong interaction physics is unparalleled by any other. His lattice gauge theory is the only approach we know how to solve a non-trivial, non-perturbative quantum field theory. In the last 15 years of his scientific career, realizing that lattice QCD has its limit, he hoped to develop new methods to solve QCD in light-front coordinates, a problem posed by Dirac in 1949 and gained considerable importance in high-energy physics through Feynman in 1968. In this talk, I will discuss these topics and argue that Ken’s lattice QCD might hold the best hope to accomplish effectively light-front quantization.
