内容简介

Roger Penrose, one of the most accomplished scientists of our time, presents the only comprehensive and comprehensible account of the physics of the universe. From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

作者简介

Roger Penrose is Emeritus Rouse Ball Professor of Mathematics at Oxford University. He has received a number of prizes and awards, including the 1988 Wolf Prize for physics, which he shared with Stephen Hawking for their joint contribution to our understanding of the universe. His books include The Emperor's New Mind, Shadows of the Mind, and The Nature of Space and Time, which he wrote with Hawking. He has lectured extensively at universities throughout America. He lives in Oxford.

I have to say, it's a masterpiece

　　蓝徽容并不心惊，淡然地回望着他，他的五官，与简璟辰有几分相似，只是眉眼更为开阔，多了几分豪飞之意，他的眼神，也比简璟辰多了几分威严肃杀之意。

书应该不错。很有趣，还分内容进行难度提示，不过1000多页...书的装帧是胶水，不过这些都不是问题，赶紧领略内容吧！——下面请尚未购买者自行略去不看，“赫拉克利特（Heraclitus）时间”——事无定事，万物皆流。我们看到的兔子，是完美的“本质兔子”的苍白投影。那只完美的、本质性的柏拉图式兔子（以及所有完美的几何图形）就高悬在理想空间的某处。有血有肉的兔子可能会因变化而有所不同，但是它们的变异总披看作是从“完美兔性”(theidealessenceofrabbit）的偏差。 这幅图策是多么彻底地背离进化啊！柏拉图主义者将兔子的任何变化，都视为对“本质兔”的散乱偏离，并且，总是有抗拒变化的阻力——仿佛所有真正的兔子和天上的“本质兔”都被无形的松紧绳拴在了•起。生命进化的观点则与此完全相反―后代可以无限地脱离他们祖先的存在形式，井且每一次背离，都会成为未来变种的潜在祖先。没有什么永恒的‘兔性”(rabbitiness)，也没有什么高悬在天空的“本质兔”，只有一群群毛茸茸的、长耳的、食粪的、胡须颇动的个体，在大小、形状、颜色和癖好方而，呈现某种统计分布。旧分布中偏在一隅的长耳兔，也许会发现自己在后来的地质时期成了新分布的中，心。假定兔子的世代有足够庞大的代数，其祖先和后代的分布共至会没有交集：祖先拥有的最长的耳朵，可能比后代中最短的耳朵还要短。进化论是多么深刻，人生何尝不是呢！

这座就以设计师名字命名的图书馆的屋顶上伫立着四座石像，代表的是四门最古老的学科：神学、法学、物理学和数学。馆内的书架、桌椅等精致的家具也都由莱恩亲自设计。

我们再从宏观上来看，太阳系是由发光发热的巨大的核反应堆和围绕太阳旋转的几大行星组成，太阳系中的行星，都是围着太阳旋转的，不难发现，这种结构与原子的结构何其相似！银河系的结构正像是我们了解的其它物质一样，如果我们以更大的视点来看它，说它是某个巨型物质的一个分子或是一个组织细胞不是也很确切吗？
