A mind-bending exploration of the deepest questions about the Universe For a physicist, the world and its workings are all the ebb and flow of information. Living beings, for example, are transient patterns of information, passing on the recipe for our basic forms to future generations using a four-letter digital code called DNA. Vlatko Vedral explores the mind-stretching implications of interpreting the Universe in terms of information. His energetic investigation takes us to some of the deepest questions about the Universe and also some of the most everyday, including stock-market predictions, planning a diet, and successful dating. He gives us brilliant explanations of the nature of information, the idea of entropy, and the roots of this thinking in thermodynamics. He describes the bizarre effects of quantum behaviour-effects such as 'entanglement'-what Einstein called 'spooky action at a distance'. He explores cutting-edge work on harnessing quantum effects in hyperfast quantum computers, and how recent evidence suggests that the weirdness of the quantum world, once thought limited to the tiniest scales, may reach into the macro world and make teleportation a reality. And then there is the ultimate question: where did all of the information in the Universe come from? The answers he considers are exhilarating, and challenge our concept of the nature of particles, of time, of determinism, and of reality itself.
In Decoding Reality
, Vlatko Vedral offers a mind-stretching look at the deepest questions about the universe where everything comes from, why things are as they are, what everything is.
The most fundamental definition of reality is not matter or energy, he writes, but information and it is the processing of information that lies at the root of all physical, biological, economic, and social phenomena. This view allows Vedral to address a host of seemingly unrelated questions: Why does DNA bind like it does? What is the ideal diet for longevity? How do you make your first million dollars? We can unify all through the understanding that everything consists of bits of information, he writes, though that raises the question of where these bits come from. To find the answer, he takes us on a guided tour through the bizarre realm of quantum physics. At this sub-sub-subatomic level, we find such things as the interaction of separated quantum particles--what Einstein called "spooky action at a distance." In fact, Vedral notes, recent evidence suggests that quantum weirdness, once thought to be limited to the tiniest scale, may actually reach into the macro world and make teleportation a real possibility. It is in quantum physics, he writes, that we really can find the answer to the ultimate question of life, the universe, and everything.
