Editorial Reviews

From Publishers Weekly

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.

From Booklist

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

Format: Hardcover
In reviews thus far of "Decoding the Universe," both formal and informal, there is a pattern of confusion and disorientation about the book's real topic.

Take Laura Miller's review on Salon.com for example. Though it is largely a positive review, she introduces the book as a book on cosmology and compares it, as a few other reviewers have, to Seth Lloyd's book on quantum computing, "Programming the Universe."

Yes it is true, Charles Seife does write about the universe and he does have a chapter on quantum computing, but there is more to the book than multiverses and quantum computing.

In fact, the very reason for this general sense of disorientation may be the real central concept of the book - Information. For most of us, information is, dates, faces, or names of places. It is an abstract concept. Contrast that to the concept of "Information" Seife introduces, a concept that is physical, a concept that is probabilistic and one that governs the behaviors of atoms, black holes and all living beings.

The word "Universe" in the title may have been a bit misleading, conjuring a, somewhere `out there' in a subatomic realm, far far away, image. The universe in Seife's title is not just about the universe out there in the dark sky, it really alludes to a `Universal Law' that applies to all things in our universe. Seife's book is really about an emerging law, that may well become, once all the debates come to an end, the most fundamental law of the universe.

"Information can neither be created nor destroyed.

Charles Seife has not been the first to proclaim that the most fundamental entity in the universe is "information". Physicist John Wheeler, David Bohm, and Tom Siegfried among others have held this view as well, but no other author I've read has gone to such lengths to establish this idea as an undeniable conclusion.

In a consise staight-forward format, Siefe delves into biology, computer science, cosmology, Relativity, and quantum theory, to establish the notion that information and the second law of thermodynamics are intricately linked. And he does this without ever allowing the reader to become lost or confused.

Information is always physical, whether it is marks on paper, holes in a punch card, atoms in an electo-magnetic state on a CD, photon polarization, or up/down spin on an electron. All information has a physical representation. And like any physical thing in our universe, it abides by the laws of nature, including the laws of thermodynamics and Relativity. Information, like energy, can neither be created nor destroyed. Infomation always moves toward the most probable state: maximum entropy. And no information can travel faster than the speed of light.

The qubit, which is the quantum representation of the classical bit, abides by the laws of quantum physics, and despite the weird instantaneous quantum connection between particles in an entangled state demonstrated by Bell's theorem of inequality; the qubit does not violate faster-than-light communication. Oddly, the qubit does violate one tenant of Relativity--that no effect can precede its cause. It seems that the time-asymetrical qubit has no "before" or "after".

104 of 131 people found the following review helpful By Dennis Littrell HALL OF FAMETOP 1000 REVIEWERVINE VOICE on November 3, 2006
Format: Hardcover
Seife begins with an introduction to information theory. He talks about redundancy and the relationship of entropy and probability to information. He recalls the work of Turing and Shannon. Then he reviews relativity as he leads us to quantum mechanics. He recalls the paradox of Schrodinger's cat and other peculiarities of QM.

In general what he tries to explain to the general reader is how science is reinvestigating the fundamentals of physics from the standpoint of information theory, which apparently is going to replace physics. If Seife is correct, professors of physics are going to become professors of information theory, if that hasn't already happened. To me replacing matter and energy with information is not helpful. But to physicists apparently it is not only helpful but something splendid.

Consequently, there is a kind of "gee whiz" quality to Seife's expression, a quality that I found somewhat off-putting. Enthusiasm is fine and the ready acceptance of new ideas is agreeable when the ideas have experimental backing. For example he writes (speaking of a hypothetical creature inside the event horizon of a black hole): "...no matter how hard it tried, the creature would be utterly unable to send us a message...The pull of the black hole is too strong. Even if there were a huge population of these creatures swirling around the black hole, all screaming and signaling as loud as they possibly could, Earth would never receive a single bit or qubit of information about them." (pp. 242-243)

Considering the physical conditions inside a black hole, the image of creatures "screaming and signaling" is absurd to say the least, and frankly ludicrous.
