Starred Review. In a book that's all but impossible to put down, science journalist Seife (Alpha & Omega) explains how the concepts of information theory have begun to unlock many of the mysteries of the universe, from quantum mechanics to black holes and the likely end of the universe. Seife presents a compelling case that information is the one constant that ties all of science, indeed all of the universe, together. His skill with language permits him to do what many have tried and few have accomplished—making complicated concepts of quantum mechanics accessible to the average reader. Seife demonstrates how quantum oddities so alien to classical physics actually are consistent with the same physical laws that govern the world we see. For example, the fact that entangled particles half a universe away can instantaneously communicate with one another (what Einstein called "spooky action" at a distance), apparently violating the law that nothing can exceed the speed of light, can be understood through information theory. Seife takes all of this to a most bizarre, but logical, conclusion reached by many cosmologists: the universe as we know it is but one of an infinite number of universes, all brought into being through information transfer.

Bit by bit, cutting-edge physicists are acclimatizing themselves to the notion that the universe is like a computer, its events akin to information processing. Seife treks through the thinking that implies humanity's final demotion from emanation of godhead to binary digits. An excellent popular science author (Alpha and Omega, 2003), Seife opens with the history of thermodynamics and the equation of entropy. This equation is the foundation of information theory, which was formalized in 1948 by Claude Shannon, who also coined the term bit. The author then delves into why the idea of the universe-as-information appeals to theorists, resting his presentation on the weirdness of wave-particle duality. Challenging but rewarding fare for attentive general science readers, who might also be interested in Programming the Universe (2006), by information theorist Seth Lloyd. Gilbert Taylor
