Everything in the universe, from the molecules in our bodies to the heart of a black hole, is made up of bits of information. This is the radical idea at the center of the new physics of information, and it is leading to exciting breakthroughs in a vast range of science, including the invention of a new kind of quantum computer, millions of times faster than any computer today. Acclaimed science writer Tom Siegfried offers a lively introduction to the leading scientists and ideas responsible for this exciting new scientific paradigm.

Editorial Reviews

Library Journal
Siegfried, the science editor of the Dallas Morning News, presents the radical idea that information is not merely something abstract and intangible but that it is physical. He asserts that bits and bytes of information are the foundation of reality; in other words, "it from bit." He argues that everything in the universe, from the biology of living things to the cosmology of a black hole, is constructed of nothing more substantial than bits of information. Whether one agrees with this far-out concept or not, Siegfried weaves a provocative and convincing argument, supported by a plethora of scientific and mathematical research cited in numerous sources recommended for further reading. This is the new physics of information, and Siegfried says it is leading to major breakthroughs in a vast range of science such as teleportation and the development of "quantum computers" designed to decode the mysteries of DNA and human consciousness.

In this book, author Tom Siegfried guides his readers on a tour of fascinating discoveries and theories plucked from science headlines. He highlights a wide subject field in modern research and describes how this research is interpreted through the metaphor of the computer. His tour begins with quantum mechanics, passes through information theory, neuroscience, and complexity, and arrives ultimately at cosmology and the fabric of space and time. Without delving into challenging technical details, Siegfried provides an insight into how concepts of information and information processing have become important aspects of science. He gives the reader a flavor of the research and ties the different areas together with information. His broad view of many different areas of research provides a superb starting point for the further study of any one field.

A hint of how difficult modern research can be to understand, and the only limitation of the book, is that quite a few of the references mentioned for further reading were written by the author himself for the Dallas Morning News. There are references to other books written for the general public and a few journal articles, but following any particular research topic further would require a search of the literature. Descriptive and intriguing, The Bit and the Pendulum is written in a familiar and entertaining style. The interrelationships described among current research in diverse fields make the volume a very timely read. I recommend the book for students, teachers, science hobbyists, and scientists of all disciplines. Highly Recommended, Grades 7-College, Teaching Professional, General Audience.

From the Publisher
* "Light stopped." So read a number of headlines over recent news articles, about scientists bringing light to a full stop in a laboratory. The more careful writers explained that actually the experiments consisted of capturing all the information about some light rays in a soup of atoms and laser beams; this information could be used to reassemble the rays later and send them on their way. "The Bit and the Pendulum" explores the possibility that everything, heaven and earth and all that is in them, is, like that light, but a manifestation of information. Physical scientists are likely to meet this idea with a dismissive shrug; they are quite happy with energy as the foundation of everything. On the other hand, information scientists are likely to find the idea quite natural and exciting. Tom Siegfried, the science editor of The Dallas Morning News, invites the general reader to come to a personal conclusion. Siegfried posits that science, particularly physics, and by extension the rational view of the universe, have been driven by a succession of metaphorical worldviews - "superparadigms." In turn, these are motivated by the dominant machines of the era. The first: The universe as clockwork (the pendulum of the title) is manifested in Newtonian mechanics. Here force is a key concept, and energy, kinetic and potential, first appears as a conserved quantity. The second, some centuries later: The universe as a large heat engine Is manifested in the theory of thermodynamics, motivated by the steam engine. Energy, the key concept, is conserved, but entropy, or useless heat energy, increases, so the universe is running down. The third, motivated by the computer, the dominant machine of today, sees the universe as a large information processor. Entropy is information.

Information has a precise definition as the state of a system. The simplest bit of information is an either-or state, a zero or one, up or down, yes or no, or a protein either active or inactive (this last connects biology and information). Any system - an atom, a human, the universe - can be completely described by the answers to a few tens of yes-no questions (20 questions, anyone?); that is, a few tens of bits. An information processor, a computer, is a system that transforms its state, according to rules, into a new state. Do not underestimate the import of all this. The thesis developed in the book is that information is not a formal way of analyzing systems and their behavior. "Information is real. Information is physical," Siegfried writes. And later: "Information is more than a metaphor -it is a new reality." And the progression of events through time is computation, so the universe is essentially a huge. If mysterious, computer.

To illustrate, Siegfried begins with the idea of teleportation: "Beam me up, Scotty." If teleportation really exists - and Siegfried shows it does in some sense - it would consist of transporting not matter but the complete information about the structure of an object, every molecule of Captain Kirk, in such a way that the information in the previous location is destroyed. In this view of reality, Siegfried says, "information is the ultimate 'substance' from which all things are made"; witness the light of the recent headlines.

This concept, at most a few decades old in this form, is controversial. Learned opinions vary from complete acceptance to laughing rejection. This book is personal journalism. The author has met with many of the principal movers and shakers. He lets them speak for themselves and recounts his own intellectual journey. He has attended the scientific meetings and read the scientific papers. His primary mentors seem to have been the physicist John Wheeler, a professor of his at the University of Texas, Austin, and the late Rolf Landauer of I.B.M., a primary figure in the physical theory of information (and a deep skeptic about some of the newer directions of exploration).

What People are saying about this

K.C. Cole
"Funny, clear, deep, and right on target, Tom Siegfried's The Bit and the Pendulum is a friendly guide to a profound revolution now taking place on the forefront of science. From the horizons of black holes to the inner recesses of the human brain, bits are us -- and everything else too. Taking a lighthearted approach to weighty ideas, Siegfried takes us into the tangled web of quantum teleportation, curled up extra dimensions of space and time, and the wetware of computational cells. He lets us get a handle on ideas that are essential for understanding the evolving world."
