5.0 out of 5 stars Fantastic science boldly conjectured, 9 Dec 2009
This review is from: The Fabric of Reality: Towards a Theory of Everything (Paperback)
As a small child, David Deutsch wanted to learn everything. This does not mean that he wanted to know everything but that he wanted to understand everything that could be understood. To this end, Deutsch recognises four strands to a deep understanding of the fabric of reality: quantum physics, epistemology, computation and genetical evolution.

The particular theories Deutsch proposes in these subjects are: the parallel universes or many worlds interpretation; Karl Popper's hypothetico-deductive model; Charles Darwin's theory of evolution by natural selection, specifically in the gene-centric interpretation given it by Richard Dawkins (the selfish gene school); and, in regard to computation, the Church-Turing conjecture of universal computation, universal virtual reality based on universal computation, Deutsch's own theory of quantum computation and artificial intelligence.

A wilder application of computation to physical reality is Frank Tippler's theory of the omega point, a state reached in the last moments of the collapsing universe, where the minds of all previous people can be resurrected.

The Fabric of Reality is altogether an excellent book, marred only by David Deutsch's insistence that anyone who doubts the many worlds interpretation does not understand quantum theory properly (and his strong hint that we are retarded by lack of imagination or honesty).
