The modern understanding of turbulence is that it is a collection of weakly correlated vortical motions, which, despite their intermittent and chaotic distribution over a wide range of space and time scales, actually consist of local characteristic 'eddy' patterns that persist as they move around under the influences of their own and other eddies' vorticity fields. Numerical simulations and experimental observations have now identified some forms and elements of 'life-cycles' of some of these structures. The articles in this volume, first published in 2000, examine a number of key questions that have engaged turbulence researchers for many years. Most involve mathematical analysis, but some describe numerical simulations and experimental results that focus on these questions. However, all are addressed to a wide cross-section of the turbulence community, namely mathematicians, engineers and scientists.

" The production of the book is up to the high standards we customarily expect of Cambridge University Press. The uniform layout of the papers stands in contrast to that of many similar collections. The Isaac Newton Institute, the organizers of the program on turbulence, the editors of this volume, the contributors, and the publisher all deserve our gradtitude for providing the setting for the presentation of this work and for so rapidly and attrctively disseminating it to the research community." AIAA Jrnl
