Programming The Universe: A Quantum Computer Scientist Takes on the Cosmos - Tapa blanda

"Seth Lloyd is an authoritative and often funny guide to this head-bending stuff...startlingly novel" (Stephen Poole Guardian)

"Lloyd does an excellent job of explaining all this in clear, accessible language... I urge you to buy the book" (John Gribbin Independent)

"Visionary and fun" (New York Times)

"His excellent book explains the science in terms as simple as one could hope for" (Andrew Crumey Scotland on Sunday)

"Lloyd thinks he has found a new way to explain one of the most basic questions in science: Why is the world so complex?... Fascinating and profoundly comforting... Seth Lloyd certainly gives his readers a lot of bang for their buck" (The New York Times Book Review)

IN THE BEGINNING WAS THE BIT...

The universe is made of bits of information and it has been known for more than a century that every piece of the the universe - every electron, atom and molecule - registers these bits and that information. It is only in the last years, however, with the discovery and development of quantum computers, that scientists have gained a fundamental understanding of just how that information is registered and processed.

Building on recent breakthroughs in quantum computation, Seth Lloyd shows how the universe itself is a giant computer. Every atom and elementary particle stores these bits, and every collision between those atoms and particles flips the bits into a new arrangement and effortlessly spins out beautiful and complex systems, including galaxies, planets and life itself.

But every computer needs a program, the set of instructions that tell it what patterns to create. Where did the bits come from that tell the universe to create its magnificent complexity? Who - or what - is programming the universe?
