David Deutsch

The fabric of reality

Deutsch is best known for his views on quantum computing and its link to the many worlds interpretation of quantum mechanics. Naturally these subjects figure highly in this book, but I would say this isn't just a book about modern physics, in fact it's more of a philosophy book. If that's put you off then it shouldn't - this is philosophy as it should be written. In a non-technical and highly readable way, Deutsch puts forward the arguments for his view of the nature of reality, and I have to say that he is fairly persuasive - even for people like me who don't believe in the many worlds interpretation

The double slit experiment is introduced early in the book and is central to his arguments for the multiverse - he shows how this leads to the conclusion that light is being influenced by photons from other universes. He then links this in an intruiging way to the other three strands of his philosophy, which are evolution, epistemology and the theory of computation. He goes via virtual reality, time travel and his own solution to the problem of induction, and concludes that we aren't just here by chance, rather intelligent beings are an integral part of the universe. info

Product Description
For 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.
