The most successful theory in all of science (and the basis of one third of our economy) says the strangest things about the world and about us. Can you believe that physical reality is created by our observation of it? Physicists were forced to this conclusion, the quantum enigma, by what they observed in their laboratories.

Trying to understand the atom, physicists built quantum mechanics and found, to their embarrassment, that their theory intimately connects consciousness with the physical world. Quantum Enigma explores what that implies and why some founders of the theory became the foremost objectors to it. Schrodinger showed that it absurdly allowed a cat to be in a superposition simultaneously dead and alive. Einstein derided the theory's spooky interactions. With Bell's Theorem, we now know Schrodinger's superpositions and Einstein's spooky interactions indeed exist.

Authors Bruce Rosenblum and Fred Kuttner explain all of this in non-technical terms with help from some fanciful stories and bits about the theory's developers. They present the quantum mystery honestly, with an emphasis on what is and what is not speculation.

Physics' encounter with consciousness is its skeleton in the closet. Because the authors open the closet and examine the skeleton, theirs is a controversial book. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is controversial.

Every interpretation of quantum physics encounters consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself: and encounter quantum physics. Free will and anthropicprinciples become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing. Readers are brought to a boundary where the particular expertise of physicists is no longer a sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves.

The measurement problem in quantum physics (i.e. the "quantum enigma" of this volume's title) is that the wave-function in quantum mechanics evolves according to the Schrödinger equation into a linear superposition of different states, but any measurement finds the physical system in a definite state, suggesting that the act of observation has somehow converted probabilities into reality. The authors (a pair of physics professors from the U. of California at Santa Cruz) of this work are amongst those who resolve this problem by suggesting that reality is actually created by consciousness. They explain this idea to a general audience and explore its implications "beyond physics." Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)

"A remarkable and readable presentation of the basic mysteries of science, our universe, and human life. Critically important problems in our understanding are interestingly discussed with perception, depth, and careful objectivity."--Charles Townes, winner of the Nobel Prize in Physics, inventor of the laser, and Templeton Prize recipient

"Employing the simplest, correct demonstration of the Great Quantum Dilemma that I have ever seen, Rosenblum and Kuttner starkly expose the hidden skeleton in the physicist's closet."--Nick Herbert, author of Quantum Reality

"This book is unique. I know of no other which so artfully tackles two of the greatest mysteries of modern science, quantum mechanics and consciousness. It has long been suspected that these mysteries are somehow related. The authors' treatment of this thorny and controversial issue is honest, wide-ranging and immensely readable. The book contains some of the clearest expositions I have ever seen of the strange and paradoxical nature of the quantum world. Quantum Enigma is a pleasure to read, and I am sure it is destined to become a classic."--George Greenstein, Professor of Astronomy, Amherst College, Co-author of The Quantum Challenge: Modern Research on the Foundations of Quantum Mechanics

"The boundary of existence that modern physics finds itself butting against is consciousness. The cautious, sober approach of Quantum Enigma makes its astonishing conclusions all the more credible. This is an immensely important and exciting book."--Raymond Chester Russ, Editor, Journal of Mind and Behavior

"Thoroughly engaging for both seasoned physicists and interested laypersons. Fascinating, important."--Choice

Bruce Rosenblum is Professor of Physics and former Chairperson of the Physics Department at the University of California, Santa Cruz. He has also consulted extensively for government and industry on technical and policy issues. His research has moved from molecular physics to condensed matter physics and, after a foray into biophysics, has focused on fundamental issues in quantum mechanics.

After a career in industry that included two technology startups, and following a second career in academic administration, Fred Kuttner now devotes most of his time to teaching physics at the University of California, Santa Cruz. His research interests have centered on the low temperature properties of solids and the thermal properties of magnets. For the last several years, Kuttner has worked on the foundations of quantum mechanics and the implications of the quantum theory.
