Riassunto:
For a physicist, all the world is information. The Universe and its workings are the ebb and flow of information. We are all transient patterns of information, passing on the recipe for our basic forms to future generations using a four-letter digital code called DNA.
In this engaging and mind-stretching account, Vlatko Vedral considers some of the deepest questions about the Universe and considers the implications of interpreting it in terms of information. He explains 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', which Einstein called 'spooky action at a distance', and 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.
Vedral finishes by considering the answer to the ultimate question: where did all of the information in the Universe come from? The answers he considers are exhilarating, drawing upon the work of distinguished physicist John Wheeler. The ideas challenge our concept of the nature of particles, of time, of determinism, and of reality itself.
This edition includes a new foreword from the author, reflecting on changes in the world of quantum information since first publication.
Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.
Recensione:
By turns irreverent, erudite and funny, Decoding Reality is - by the standard of books that require their readers to know what a logarithm is - a ripping good read...Not since David Deutsch's magestierial 'The Fabric of Reality' has a physicist given us such a wide-ranging and intriguing picture of how quantum mechanics constructs the world. (Seth Lloyd, New Scientist)
Well written and engaging, the book provides a constant flow of new ideas. (Science)
The author evinces great enthusiasm and curiosity throughout. (Steven Poole, The Guardian)
By turns irreverent, erudite and funny, Decoding Reality is...a ripping good read. (Seth Lloyd, New Scientist)
A wide-ranging and intriguing picture of how quantum mechanics constructs the world. (Seth Lloyd, New Scientist)
Excellent, thought-provoking book. (BBC Focus Magazine, Marcus Chown)
An engaging, non-technical exploration of what the new theory of quantum information and computation tells us about life, the universe, and everything. (David Deutsch, author of The Fabric of Reality)
Let Vedral guide you skilfully through the wonderland of modern physics - where nothing is as it seems. This is the finest treatment I have read of the weird interplay of quantum reality, information and probability. (Paul Davies, author of The Eerie Silence and The Goldilocks Enigma)
Vedral's book goes to dizzying heights in answering the very big question: can one understand all of reality from a scientific point of view? (Sheldon Richmond, Science and Education)
