Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this 2004 book, is one of the leading research programs in the field. The first part of the book discus...(展开全部)

From one of the world's most distinguished scientists, the first popular book to present the controversial and exciting ideas behind quantum gravity. The Holy Grail of modern physics is a theory of the universe that unites two seemingly opposing pillars of modern science: Einstein's theory of general relativity, which deals with large-scale phenomena (planets, solar systems a...(展开全部)

Now in paperback, this text provides a self-contained introduction to applications of loop representations and knot theory in particle physics and quantum gravity. Loop representations (and the related topic of knot theory) are of considerable current interest because they provide a unified arena for the study of the gauge invariant quantization of Yang-Mills theories and gravi...(展开全部)

His first new collection of short humor in fifteen years is classic Woody Allen. Zero Gravity is the fifth collection of comic pieces by Woody Allen, a hilarious prose stylist whose enduring appeal readers have savored since his classics Getting Even, Without Feathers, Side Effects, and Mere Anarchy. This new work combines pieces that have appeared in The New Yorker along with...(展开全部)

卡洛·罗韦利，意大利理论物理学家，圈量子引力理论的开创者之一。曾在美国、意大利工作，现在法国带领量子引力研究小组。著有畅销书《七堂极简物理课》，被译为40多种语言，被誉为下一个“史蒂芬·霍金”。

What are time and space made of? Where does matter come from? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed over the last few dozen centuries. In elegant and accessible prose, Rovelli takes us on a wondrous jou...(展开全部)
