Gauge/gravity duality creates new links between quantum theory and gravity. It has led to new concepts in mathematics and physics, and provides new tools to solve problems in many areas of theoretical physics. This book is the first textbook on this important topic, enabling graduate students and researchers in string theory and particle, nuclear and condensed matter physics to...(展开全部)

Quantum field theory forms the present theoretical framework for our understanding of the fundamental interactions of particle physics. This up-dated and expanded text examines gauge theories and their symmetries with an emphasis on their physical and technical aspects. Beginning with a new chapter giving a systematic introduction to classical field theories and a short discuss...(展开全部)

'Never, never, never give in', Winston Churchill's famous quotation best sums up the life of Stephen Westaby, the world-leading cardiothoracic surgeon. This book chronicles the triumphs and failures of his surgical life, the lives saved and extended, the innovations (such as artificial hearts) he developed, and his research discoveries. Having spent his childhood in the backstr...(展开全部)

This is an introduction to the basic tools of mathematics needed to understand the relation between knot theory and quantum gravity. The book begins with a rapid course on manifolds and differential forms, emphasizing how these provide a proper language for formulating Maxwell's equations on arbitrary spacetimes. The authors then introduce vector bundles, connections and curvat...(展开全部)

Small World is a biting and very funny satire in which Martin Parr observes global tourism and the tourist's search for authentic cultures that are themselves destroyed in that search.
