"A reading of selected parts sheds interesting light on a variety of complex topics in ways that are perhaps not so easily found in modern textbooks. I would suggest such a strategy to a philosopher or historian of science, or an undergraduate or graduate student in physics. The chapters are all well written, and whatever fraction is understood will prove valuable. The book is long, and not an easy read, but well worth the effort and I highly recommend it."CERN Courier "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-Mann The 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, Édouard Brézin, 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.
