The Second Woodward Conference, held November 17-18, 1989 at San Jose State University, brought together pioneers and experts from a number of different disciplines to discuss problems involving nonlinear structures in physical systems, with emphasis on pattern formation, chaos and waves. These proceedings contain results of interest to workers in physics, chemistry, biology, materials science and mathematics. Topics discussed include: - pattern formation of bubbles, viscous fingers, electrodeposits, solidifications, chemical systems and frustrated systems - chaos, self-organized criticality and complex systems - convection and traveling waves in simple and com- plex liquids - nonlinear structures in materials such as magnetic systems, polymers, fluid dispersions, and glassy and solid thin films - other nonlinear structures in plasmas, premixed flames, biological systems etc.
