Quantum theory is extraordinarily successful, has never made a false prediction, and one-third of our economy depends on products based on it. It also tells us some very weird things. It claims that physical reality is created by observation. Until something has been observed, it is not real. And it also says that something that occurs in one place can instantaneously influence something a long way away, without there being any physical force involved. Fred Kuttner and Bruce Rosenblum worked together at the University of California, Santa Cruz, with a shared interest in explaining the profound mysteries of quantum theory. They published Quantum Enigma in 2011, with the aim of setting out the accepted explanation of quantum theory in an accessible way. This book is a summary of Quantum Enigma. It largely follows the same structure as the chapters of the original, and finishes with a brief conclusion. This summary is unofficial, and has not been endorsed by the authors.

In trying to understand the atom, physicists built quantum mechanics, the most successful theory in science and the basis of one-third of our economy. They found, to their embarrassment, that with their theory, physics encounters consciousness. Authors Bruce Rosenblum and Fred Kuttner explain all this in non-technical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, emphasizing what is and what is not speculation. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is heatedly controversial. But every interpretation of quantum physics involves consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum mechanics. Free will and anthropic principles 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 the only sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves. In the few decades since the Bell's theorem experiments established the existence of entanglement (Einstein's "spooky action"), interest in the foundations, and the mysteries, of quantum mechanics has accelerated. In recent years, physicists, philosophers, computer engineers, and even biologists have expanded our realization of the significance of quantum phenomena. This second edition includes such advances. The authors have also drawn on many responses from readers and instructors to improve the clarity of the book's explanations.
Following the overthrow of the classical world picture by the findings of quantum mechanics, physicists have proposed a broad gamut of alternative worldviews. The Quantum Enigma begins with the major recognition that each of these suffers from a certain "residual Cartesianism" that has been smuggled in unconsciously. It turns out that the moment this hidden and problematic premise is discarded, quantum theory begins to "make sense" in a way that it never has before. As the author shows, it is now possible, for the first time, to integrate the findings of quantum physics into a worldview that conforms to the permanent intuitions of mankind. This work can be read by scientists but is also surprisingly accessible to the general reader unacquainted with the technical conceptions of physics or the quantum-reality literature. --
Quantum mechanics is one of mankind's most remarkable intellectual achievements. Stunningly successful and elegant, it challenges our deepest intuitions about the world. In this book, seventeen physicists and philosophers, all deeply concerned with understanding quantum mechanics, reply to Schlosshauer's penetrating questions about the central issues. They grant us an intimate look at their radically different ways of making sense of the theory's strangeness. What is quantum mechanics about? What is it telling us about nature? Can quantum information or new experiments help lift the fog? And where are we headed next? Everyone interested in the contemporary but often longstanding conundrums of quantum theory, whether lay reader or expert, will find much food for thought in these pages. A wealth of personal reflections and anecdotes guarantee an engaging read. Participants: Guido Bacciagaluppi, Caslav Brukner, Jeffrey Bub, Arthur Fine, Christopher Fuchs, GianCarlo Ghirardi, Shelly Goldstein, Daniel Greenberger, Lucien Hardy, Anthony Leggett, Tim Maudlin, David Mermin, Lee Smolin, Antony Valentini, David Wallace, Anton Zeilinger, and Wojciech Zurek.
Following upon the overthrow of the classical world picture by the findings of quantum mechanics, physicists have proposed a broad gamut of alternative world views. The present book begins with the major recognition that each of these suffers from a certain "residual Cartesianism" that has been smuggled in, as it were, unconsciously. It turns out, moreover, that the moment one discards this hidden and problematic premise, quantum theory begins to "make sense" in a way that it never has before. As the author goes on to show, it now becomes possible, for the first time, to integrate the findings of quantum physics into a world view that is neither forced nor ad hoc, but conforms to the permanent intuitions of mankind. Surprisingly, this treatise can be read with pleasure and profit, not only by scientists, but also by readers previously unacquainted with the technical conceptions of physics or the quantum-reality literature.
Princeton, New Jersey, 1951: As a CIA operative watches from the shadows, two old men—Israeli prime minister David Ben-Gurion and world-renowned scientist Albert Einstein—enter Einstein’s home to speak privately about nuclear weapons and the existence of God. Present Day Cairo, Egypt: Over lunch in the Muslim quarter, world-famous cryptanalyst Thomas Noronha is hired by a beautiful dark-haired woman, Ariana Pakravan, to decipher a cryptogram hidden in a recently discovered secret document under heavy security in Tehran. A manuscript penned by Albert Einstein, it is titled Die Gottesformel: The God Formula. So begins a remarkable adventure that spans the world, as Thomas and Ariana pursue the dangerous truth behind an incredible document. The Einstein Enigma is a breathtaking fusion of science, thriller, and religion, a mind-bending trip to the source of time, the essence of the universe, and the meaning of life itself.
The intellectual adventure story of the "double-slit" experiment, showing how a sunbeam split into two paths first challenged our understanding of light and then the nature of reality itself--and continues to almost two hundred years later. Many of science's greatest minds have grappled with the simple yet elusive "double-slit" experiment. Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe. How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit? With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take.

Quantum theory is the bedrock of contemporary physics and the basis of understanding matter in its tiniest dimensions and the vast universe as a whole. But for many, the theory remains an impenetrable enigma. Now, two physicists seek to remedy this situation by both drawing on their scientific expertise and their talent for communicating science to the general reader. In this lucid, informative book, designed for the curious, Lederman and Hill make the seemingly daunting subject of quantum physics accessible, appealing, and exciting. Their story is partly historical, covering the many "Eureka" moments when great scientists-Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, and others-struggled to come to grips with the bizarre realities that quantum research revealed. Although their findings were indisputably proven in experiments, they were so strange and counterintuitive that Einstein refused to accept quantum theory, despite its great success. The authors explain the many strange and even eerie aspects of quantum reality at the subatomic level, from "particles" that can be many places simultaneously and sometimes act more like waves, to the effect that a human can have on their movements by just observing them! Finally, the authors delve into quantum physics' latest and perhaps most breathtaking offshoots-field theory and string theory. The intricacies and ramifications of these two theories will give the reader much to ponder. In addition, the authors describe the diverse applications of quantum theory in its almost countless forms of modern technology throughout the world. Using eloquent analogies and illustrative examples, Quantum Physics for Poets renders even the most profound reaches of quantum theory understandable and something for us all to savor.
Following the overthrow of the classical world picture by the findings of quantum mechanics, physicists have proposed a broad gamut of alternative world views. This book begins with the major recognition that each of these suffers from a certain ?residual Cartesianism? that has been smuggled in unconsciously. It turns out that the moment one discards this hidden and problematic premise, quantum theory begins to ?make sense? in a way that it never has before. As the author shows, it is now possible, for the first time, to integrate the findings of quantum physics into a world view that is neither forced nor ad hoc, but conforms to the permanent intuitions of mankind. Surprisingly, this treatise can be read not only by scientists, but also by readers unacquainted with the technical conceptions of physics or the quantum-reality literature. Wolfgang Smith graduated from Cornell University at age eighteen with majors in physics, philosophy, and mathematics.After taking an M.S. in physics at Purdue he pursued research in aerodynamics, where his papers on diffusion fields have provided the theoretical key to the solution of the re-entry problem for space flight.After receiving a Ph.D. in mathematics from Columbia University, Dr. Smith held faculty positions at M.I.T, U.C.L.A., and Oregon State University, where he served as Professor of Mathematics until his retirement in 1992. In addition to numerous technical publications (relating to differential topology), Dr. Smith has published three previous books and many articles dealing with foundational and interdisciplinary problems. He has been especially concerned to unmask conceptions of a scientistic kind widely accepted today as scientifictruths. ?Wolfgang Smith is as important a thinker as our times boast, and this is his most seminal book.? ?Huston Smith ?The Quantum Enigma is of great importance not only for the philosophy of science, but also for the whole domain of human knowledge, and should be disseminated as widely as possible.? ?Seyyed Hossein Nasr ?Unusually interesting . . . profoundly enlightening.? ?Henry Margenau
