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
第一章 万有之理 早前看《数学游戏》,有一篇文章借用一种简单的“蚂蚁”游戏得出结论说,对于很简单的行为规则,我们都没有能力预言它的结果,那又如何寻求万有之理呢?当时我认为,解释世界也许不可能,但是人类最终可以描述世界。象伽利略做的那样,只说“是什么”,不说“...
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...

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
评分虽然很爽但是一半不懂,等聪明一点以后再看一遍=-=
