In the two volumes that comprise this work Roger Penrose and Wolfgang Rindler introduce the calculus of 2-spinors and the theory of twistors, and discuss in detail how these powerful and elegant methods may be used to elucidate the structure and properties of space-time. In volume 1, Two-spinor calculus and relativistic fields, the calculus of 2-spinors is introduced and develo...(展开全部)

This volume introduces and systematically develops the calculus of 2-spinors. This is the first detailed exposition of this technique which leads not only to a deeper understanding of the structure of space-time, but also provides shortcuts to some very tedious calculations. Many results are given here for the first time.

There are some wonderfully bizarre ideas in physics, and it seems a pity to keep them locked up in small boxes, available only to an esoteric coterie of key holders. Brian Ridley's book sets out to survey in simple, nonmathematical terms what physics has to say about the fundamental structure of the universe. He deals with all the basic concepts of modern physics: elementary pa...(展开全部)

One fine day, and I know how romantic and old-fashioned that sounds, but it is what happened in my case, I packed a rucksack, took leave of my mother, and caught the train to Breda. An hour later - you know how small the Netherlands is - I was standing at the side of the road on the Belgian border sticking my thumb in the air, and I have never really stoppped since.' After maki...(展开全部)

Since making his first voyage as a sailor to earn his passage from his native Holland to South America, Cees Nooteboom has never stopped traveling. Now a selection of his best travel pieces are gathered together in this collection of immense range and depth, informed throughout by author's wonderful sense of humor. From exotic places like Isfahan, the Gambia, and Mali, to seem...(展开全部)
