This special volume is dedicated to Geoffrey Chew who passed away on April 12, 2019, at age 94. He is best known as the architect and passionate champion of the bootstrap concept, sometimes called nuclear democracy. His work influenced generations of particle physicists. His passion for physics was an inspiration for his many students and associates. From the Chew-Low theory for meson-nucleon scattering to Analytic S-Matrix, Regge Poles, and Bootstrap principle, his originality left its mark in ways that continue to the present. With contributions from Chew''s former collaborators, students, and friends, the book will cover various facets of his life and impact on physics.Contributors include Steven Weinberg, Steven Frautschi, Gabriele Veneziano, Peter Landshoff, Carl Rosenzweig, Basarab Nicolescu, William Frazer, David Gross, John Schwartz, Ling-Lie Chau, Chung-I Tan, Richard Brower, Carleton DeTar, R Shankar, David Kaiser, Fritjof Capra, and others.

This volume concentrates on three main areas of current research in high energy physics: (1) multiparticle and diffractive production in perturbative and nonperturbative QCD, (2) confinement-deconfinement mechanism and the RHIC physics, and (3) interface between high-energy collisions and cosmic-ray/astro-physics. The specific topics covered include: QCD at high energies, diffractive production, and small-x physics, multiparticle production and systematics: correlations and fluctuations, hadronic final states in e+e-, lepton-hadron and hadron-hadron collisions, relativistic heavy ion collisions, interface between high-energy collisions and cosmic-ray physics, and recent development in deconfinement.

This is a volume in honor of Professor Peter Carruthers on the occasion of his 61st birthday. It is a unique collection of papers by the world''s leading experts, describing the most exciting developments in many areas of theoretical physics. While traditionally physics is driven to ever smaller and simpler systems, end-of-this-century scientists see themselves confronted with complex systems in many of their areas. It is just this interdisciplinary character of complexity that is addressed in this book, with topics ranging from the origin of intelligent life and of universal scaling laws in biology via heartbeats, proteins, fireballs, phase transitions, all the way to parton branching in collisions of elementary particles at high energies. The contributions include extensive discussions on complexity (M Gell-Mann, M Feigenbaum, D Champbell, D Pines and L M Simmons), neutrino masses (R Slansky and P Rosen), high temperature superconductors (D Pines), low Moon (M Feigenbaum), origin of intelligent life (S Colgate), chaos of the heart (M Duong-Van), origin of universal scaling laws in biological systems (G West), critical behavior of quarks (R Hwa), status of LEGO (S Meshov), disoriented chiral condensate (F Cooper), and many others.

These proceedings contain descriptions of the latest experiments and results in a variety of hot topics, such as the growth of total cross sections, the ratio of real to imaginary parts of forward scattering amplitudes, etc. Current theories of particle interaction based on QCD were presented and confronted by the latest experimental results from FNAL, CERN, HERA and elsewhere. The theoretical situation seems less clear, or at least more open to argument and criticism, leveled by the different groups responsible and present at the workshop.
