我可以保证，这真是一本很有趣的书。跟随作者，你可以进入爱因斯坦的梦境，坐在牛顿老师的课堂，来到星光实验的现场……最近距离接触科学的真相。 本书上部（前五章）和大家一起回顾物理学走过的坎坷历史，这段历史的精彩程度不亚于任何一段战争史。在伽利略、牛顿等巨星纷纷谢幕之后，超级巨星爱因斯坦闪亮登场。他就像一位横空出世的大侠，无门无派，但出手即震惊天下，他的绝招就是“相对论”。 中间的第六章是一段小说体的跨越半个多世纪的真实历史故事，这个故事尘封已久，现在很多年轻人甚至都不敢相信这就是现实，但真相往往比小说更惊人。 最后四章是本书的下部，下部比上部更精彩，结构更宏大，故事更神奇，真相更惊人。在下部中，作者将细致地剖析时空的真相，带你领略神奇的四维时空奇景，了解整个宇宙的终极图景，再回到原子的深处见识不可思议的微观世界，最后看一看当下物理学的最新进展——万物理论。

This landmark text offers a rigorous full-year graduate level course on gravitation physics, teaching students to: • Grasp the laws of physics in flat spacetime • Predict orders of magnitude • Calculate using the principal tools of modern geometry • Predict all levels of precision • Understand Einstein's geometric framework for physics • Explore applications, including pulsars and neutron stars, cosmology, the Schwarzschild geometry and gravitational collapse, and gravitational waves • Probe experimental tests of Einstein's theory • Tackle advanced topics such as superspace and quantum geometrodynamics The book offers a unique, alternating two-track pathway through the subject: • In many chapters, material focusing on basic physical ideas is designated as Track 1. These sections together make an appropriate one-term advanced/graduate level course (mathematical prerequisites: vector analysis and simple partial-differential equations). The book is printed to make it easy for readers to identify these sections. • The remaining Track 2 material provides a wealth of advanced topics instructors can draw from to flesh out a two-term course, with Track 1 sections serving as prerequisites.
