'Kenneth Wilson was a brilliant and creative contributor to the work on renormalization groups and phase transitions. He applied his multifaceted genius to condensed matter physics as well as nuclear and elementary particle physics.'by Murray Gell-MannThe purpose of bringing out this volume is to commemorate the memory of Ken Wilson and to preserve the legacy of his ground-breaking advances. This volume brings together a collection of articles written by colleagues of Ken Wilson as well as fellow physicists and scholars - some of who knew him personally and others who are knowledgeable about his sterling contributions to the foundations of theoretical physics.To commemorate the memory of Ken Wilson, many leading and illustrious physicists have contributed to this volume - Ian Affleck, Belal E Baaquie, Ken Bowler, Edouard Brezin, Tohru Eguchi, Michael E Fisher, Paul Ginsparg, Domenico Giuliano, Stanislaw Glazek, Bailin Hao, Kerson Huang, Roman Jackiw, Richard Kenway, H R Krishnamurthy, N D Mermin, Stuart Pawley, Michael Peskin, Alexander Polyakov, John Schwarz, R Shankar, Akira Ukawa, David Wallace, Franz Wegner, Steven Weinberg, and Anthony Zee.
