General Relativity provides an unusually broad survey of the current state of this field. Chapters on mathematical relativity cover many topics, including initial value problems, a new approach to the partial differential equations of physics, and work on exact solutions. The chapters on relativistic cosmology and black holes explore cosmology. Other chapters deal with gravitational waves, experimental relativity, quantum gravity, and aspects of computing in relativity. The book will be useful both to postgraduates and to established workers in the field.

This volume crosses the boundaries of physics' traditional subdivisions to treat scattering theory within the context of classical electromagnetic radiation, classical particle mechanics, and quantum mechanics. Includes updates on developments in three-particle collisions, scattering by noncentral potentials, and inverse scattering problems. 1982 edition.

Now in paperback, the main theme of this book is the study of geometric properties of general sets and measures in euclidean spaces. Applications of this theory include fractal-type objects such as strange attractors for dynamical systems and those fractals used as models in the sciences. The author provides a firm and unified foundation and develops all the necessary main tools, such as covering theorems, Hausdorff measures and their relations to Riesz capacities and Fourier transforms. The last third of the book is devoted to the Beisovich-Federer theory of rectifiable sets, which form in a sense the largest class of subsets of euclidean space posessing many of the properties of smooth surfaces. These sets have wide application including the higher-dimensional calculus of variations. Their relations to complex analysis and singular integrals are also studied. Essentially self-contained, this book is suitable for graduate students and researchers in mathematics.

Lavishly illustrated and annotated, this first and definitive collection of letters to and from the great English playwright provides a divine portrait of an age, from the Blitz to the Ritz and beyond. "Superb.... The portrait of a complex, charming, driven, serious and, frankly, courageous artist." —The Wall Street Journal The incomparable Noël Coward loved to correspond with friends, enemies, the famous and infamous, the talented and the powerful, including Virginia Woolf, Winston Churchill, Greta Garbo, Laurence Olivier, Katharine Hepburn, Marlene Dietrich, Lawrence of Arabia, Somerset Maugham, and many more. Granted unlimited access to the Coward archive, Barry Day presents many never-published letters and has unearthed new, startling evidence of Coward's wartime work as a spy. Along with 191 rare photographs, these letters bring to life the people and events that shaped the twentieth century—and a remarkable man who made his own indelible mark at the heart of it.
