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
Imagination is a straightforward form of virtual reality. What may not be so obvious is that our ‘direct’ experience of the world through our senses is virtual reality too. For our external experience is never direct; nor do we even experience the signals in our nerves directly — we would not know what to make of the streams of electrical crackles that they carry. What we experience directly is a virtual-reality rendering, conveniently generated for us by our unconscious minds from sensory data plus complex inborn and acquired theories (i.e. programs) about how to interpret them.

So once again, any theory of the structure of the universe in all but its earliest stages must take a position on what life will or will not be doing by then. There is no getting away from it: the future history of the universe depends on the future history of knowledge. Astrologers used to believe that cosmic events influence human affairs; science believed for centuries that neither influences the other. Now we see that human affairs influence cosmic events. (查看原文)

科学就是提出对世界更好的解释。一个完整的“万物理论”是由四条线构成：量子物理，计算理论，进化论还有认识论。是那种一看目录就知道很牛的书，可惜感觉作者写得有点啰嗦，不太清楚他最初是想写出来给同行们作为消遣，还是给大众一些启蒙。我决定把他和 Naval 录的播客找来听听了。

读了几章就发现自己太膨胀了，居然还读这本书的英文版。一半的章节都是英文版比对着中文版看的，好多地方也没看懂。没办法，物理没学好。。。

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?

What's more important is the way of discovering and understanding knowledge, especially the four strands of knowledge.
