Quantum Physics: Illusion or Reality? (Canto) [Paperback]

Alastair I. M. Rae (Author)

Book Description

Publication Date: October 25, 2004 | ISBN-10: 0521542669 | ISBN-13: 978-0521542661 | Edition: 2

The concept of Quantum Physics led Einstein to state that "God does not play dice". The difficulty he, and others, had with Quantum Physics was the great conceptual leap it requires taking from conventional ways of thinking about the physical world. Alastair Rae's introductory exploration into this area has been hailed as a "masterpiece of clarity" and is an engaging guide to the theories offered. This revised edition contains a new chapter covering theories developed during the past decade. Alastair Rae has been a Lecturer, a Senior Lecturer, then Reader in Quantum Physics in the School of Physics and Astronomy at University of Birmingham from 1967-2003. His publications include the First Edition of Quantum Physics, (Cambridge, 1994) and Quantum Mechanics (Institute of Physics, 2002), now in its Fourth Edition. First Edition Pb (1994): 0-521-46716-0

This review is from: Quantum Physics: Illusion or Reality? (Canto) (Paperback)

I'm not a math physics person, but I enjoy learning what I can about them, which is why I purchased this book. I almost put it aside as I felt some of the first few pages were over my head, but I decided to look upon it as stretching exercises for the mind, and managed to reach a tolerable comprehension of the material. Thereafter the book was both understandable and thoroughly readible. I found intriguing the philosophical implications of quantum physics. Particularly interesting was the author's discussion of Popper and Eccles's concepts of the 3 worlds of reality: the world of objects, of the human mind and of the products of the human mind. The implication of human consciousness in cetain physical interactions and the possiblity that consciousness actually creates reality itself was the topic of several pages. The author also briefly touches upon artificial intelligence, multiple-world hypothesis, the effect of size on expected theoretical outcomes, and time and its direction. It was a thoroughly enjoyable book.

This review is from: Quantum Physics: Illusion or Reality? (Canto) (Paperback)

Since the formulation of quantum theory in the 1920s the Copenhagen Interpretation of reality has been the mainstream view among physicists. But this interpretation has been uncomfortable for many, because it raises a number of paradoxes. The lack of cause and effect, (indeterminism), the so called "observer effect (quantum measurement problem), and non-locality, are among them.
Waisting no time in this 118 page book, Alastair Rae grabs the reader in the very first sentence of the book by quoting Albert Einstein's famous pronouncement: "Does God play dice [with the universe]?"
Using impeccable logic and only a bit of mathematical jargon, which can be circumvented by the reader, Rae sets out to solve many of these paradoxes. Citing experiments with polarized photons of light, he asks: What exactly constitutes a measurement? Does a measurement occur when a record is made? Or does it take consciousness to collapse the wave into a definitive particle? Is there a resolution to the Schrodinger's Cat paradox? How can we explain nonlocality?
Rae systematically entertains and rebuts in a convincing and objective way many different philosophies put forward to make sense of quantum reality. Some have claimed, most notably Niels Bohr, that it's the interaction of the partilce with a macor-measuring device that instigates the collapse. Others believe that it takes a consciousness to create reality. Still others, looking for a way to save determinism, and circumvent the measurement problem latch on to Hugh Everett's many-world interpetation.
Ironically as Rae points out most scientists claim to be "positivists", believing that it is meaningless to speculate on unobservable quantities. yet, they apparently have no problem believing in a myriad of unobservable and unmeasureable universes, completely and irreversibly cut off from our own.
In the final two chapters Rae objectively entertains what he believes is the most likely resolution of the quantum measurement problem. His idea was first proposed by Ilya Prigonine who won the Nobel Prize for his work in the field of irreversible chemical thermodynamics. The classical idea put forward by Prigonine states that there is an irreversible arrow of time and the second law of thermodynamics is never violated. Citing Prigonine's work, Rae explains: If no measurement is made of a quantum system no impression has been made on the universe, and the information which could have been obtained can be reversed and destroyed. If, however, a measurement is made, a change of some sort has occurred, either in the measuring device or our brain. The measurement has impacted the universe in some manner, and as a result the macro system must now follow the second law of thermodynamics, which has and arrow of time and hence is irreversible.
Rae states that "if we follow Prigogine's approach, indeterminism becomes an implicit part of classical physics.
Has Alastair Rae accomplished what he set out to do in this Book? Not quite. At the beginning of the book he states that he will tackle the problem of indeterminism, yet he spends most of his time attempting to explain the quantum measurement problem which is something quite different. And when he does address determinsim it falls short on several points.
First, a Prigogine macro system is indeed unpredictable, but it is not indeterminate as Rae seems to imply. Rather, it is a determinate and irreversible system having and arrow of time and an initial cause, no matter how subtle.
Secondly, he fails to address the process of nuclear decay, and the jump of the electron from one orbit to another--both of which are "real" and indeterminate.
Finally, in regard to the quantum measurement problem. Rae does not take into account recent experiments done with photons as cited in Scientific American (November 1991). In this particular experimental set-up at the Universtity of Rochester, researchers demonstrated that "The mere possibility that the paths can be distinguished is enough to wipe out the interference pattern." There is no measurement made, no record made, and no interaction with a macro system. Yet, the collapse of the wave happens without interacting with a macro sytem. Therefore, it seems that Ray's explanation of a resolution to the problem by creating a record in a classical Prigogine system is invalid.
This is still a very well written, concise, and provacative book and I would recommend it for those who want to understand the basic principles and paradoxes of quantum reality. This review written by: Quantum Reality1, author of "Quantum Reality: A New Philosophical Perspective."

Bringing complex topics to a level where they can be understood by beginners is an art. Alastair Rae does just that, and should be congratulated for it. His chronological explanations of the basic Quantum Physics notions make you feel welcome in a field of Science otherwise perceived as closed to most novices.
