One of my favorite head trips is considering whether our reality is actually a control system of some kind. Quite a few people much smarter than me have theorized about the physics of this idea, that the entire universe may be made of information, of bits. Some physicists go as far as suggesting that the universe isn't like a computer, but rather it is a computer. One such person is Vlatko Vedral, a professor of quantum information science at Oxford University. Vedral has just published a new non-technical book about this mindbending field of inquiry, titled Decoding Reality: The Universe as Quantum Information. I haven't read Decoding Reality yet, but I'm always up for some quantum weirdness from those who've turned pro. Above is a video interview with Vedral from The Guardian.
