A pioneering and accessible book integrating recent advances in theoretical physics and computer scienceFor David Deutsch, a young physicist of unusual originality, quantum theory contains our most fundamental knowledge of the physical world. Taken literally, it implies that there are many universes "parallel" to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview -- one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible -- the subject of this daring, challenging book.The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here -- for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert -- is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence."Full of refreshingly oblique, provocative insights". -- The New York Times Book Review
本书的作者David Deutsch是牛津大学的物理学家,搞的专业是量子计算。从他的专业研究出发,他通过量子的眼睛,试图解释整个世界。他说,存在多重宇宙。一个粒子有上百万个幽灵副本,每一个粒子存在于一个宇宙当中,这样就构成多重宇宙。也就是说,有许多其他的宇宙,也有许多...
评分(并非专业,只能评价此书风格) 多伊奇的这本书保留了那个时代的两个鲜明特色,非常雄辩,又很敏捷,速度惊人。 这本书的写法很有些伽利略的风范。与当今物理学著作的典型写法不同,近现代物理学肇造时期的“学术著作”,采取的多是对话形式,其中最经典的就是伽利略的《关于...
评分 评分作者试图以四大理论——量子物理、认识论、计算理论和进化论来构建对宇宙乃至万物的认识。摘录一些有益的观点: 科学的目的是提供解释,而不是作出预测 凸现性:不能从还原主义的低层级角度推导出来(提供解释)的高层级现象 科学认识:比其他理论更好(解释性上),且可以随着...
评分这本书就一些有趣的话题,有选择性的介绍了一些当今科学的观点,而且通俗易懂,重要的是,书中无时无刻不在提醒着读者一种做科学研究的方法,请注意作者本身就是量子科学家,所以这些方法有相当的可信性. 此书特别适合刚从高考的桎梏中解脱,将上大学的同学们,绝对会给你耳目...

评分抛开繁琐的哲学讨论,研究具体问题,在纯粹的实证主义和相对主义间找到平衡点
评分很难啃的书。前边分别介绍四个理论支柱时候比较精彩,但综合到一起的时候觉得这四个理论没有粘合的非常紧密?
