From: maxwell on 28 Oct 2009 20:19 This is the first part of a review of The Theory of Elementary Waves (TEW) by Lewis E. Little. The focus will be on Littles recently published book but, for those readers who wish to save money, the original paper (same title, same theory) was published in Physical Essays in 1996 and is accessible online at http://elementarywaves.com/TEW96paper.html .. This review will be a more detailed discussion of the book than the one written by science writer Brian Clegg in Popular Science, a magazine he edited, (http://www.popularscience.co.uk/reviews/ rev449.htm ) and is designed to help readers of this review to make a decision between either wasting any further time on this theory or to read the original paper in depth or even, perhaps, to buy the book. A quick Google search on the complete phrase (TEW) will provide nearly 400,000 hits so there is obviously some interest in this theory. The book was published in 2009 and is available through Amazon ( http://www.amazon.com/Theory-Elementary-Waves-Explanation-Fundamental/dp/0932750842 ); the majority of public reviews there are favorable, perhaps indicating the wide-spread dissatisfaction with the current interpretations of quantum mechanics (which I share). The book was published by New Classics Library, an organization dedicated to new models of reality and headed by Robert Prechter, who both edited this book and provided the foreword, where he acknowledges Dr Little as being as revolutionary as Copernicus. One of the first surprises in reading the book is how little this theory has changed since it first appeared in 1996. Some chapters have been re-arranged and almost all the math has been omitted. It must be said, however, that there is minimal math even in the original paper, often just quoting well-known formulae (like QED propagators) but not being used. In fact, one of the most frustrating aspects of this theory is that it has not and does not predict anything new so that its value could be determined. Littles extensive use of natural language is appropriate to discuss the philosophy of quantum mechanics but there are so few mathematical derivations (beyond the most simplistic use of algebra) that this theory runs the risk of being regarded simply as hand-waving. The book is short (about 150 small pages) and lacks both a bibliography and index, making cross-referencing difficult. Each of the twelve principal chapters covers three or four topics very briefly. The Introduction sets the scene by claiming a realist view of physics (one I share) by criticizing modern physicists who "conceive of physics not as a science dealing with real entities and their consequent behavior but instead as nothing more than a mathematical description of behavior. For another of my reviews of a recent book by a philosopher of science that criticizes this view (The Inadequacies of Phenomenology), see my earlier posts in the Foundations NG: http://groups.google.com/group/sci.physics.foundations/t/f953615ecb5eb090 As Lewis is reminding us physicists (and mathematicians always seem to forget): Behavior is always behavior of something something real. <p.5> Chapter two covers quantum mechanics (QM) and the weirdness of conventional interpretations, not the least of which is the behavior of microscopic particles covered by the complementary descriptions of waves and particles, even though these two concepts are the complete opposite of one another (point versus all of space) in other words, a self-contradiction. The paradigmatic experiment here is the double-slit scattering of non-interfering subatomic particles producing a pattern (over time) on the target screen that resembles one where the source is emitting waves that subsequently interfere with one another. As Little reminds us, waves are never observed (only point hits on the target screen are seen) <p.11> but quantum physicists leapt to the conclusion that actual waves were being emitted from the source, traveling through BOTH slits and were guiding the particles (the forward-wave hypothesis). This viewpoint resulted in the form of QM known as wave mechanics invented in 1925 by Erwin Schroedinger in analogy with geometric and wave optics. The problem is that although waves can follow multiple paths at the same time (from the source, through the slits, to the screen), localized particles can only be at one point at any one time so they must follow only one trajectory. Lewis points out that these waves only meet at the screen, a view shared by those who view the waves collapsing into a particle when they reach the screen. The logical contradictions of this interpretation do not prove that the subatomic world is weird or that standard (Aristotelian) logic does not apply but that the forward-wave hypothesis is false <p. 15>. In the next section <2.3> Lewis analyzes the famous experiment of Kaiser et al in 1992 involving neutron interferometry where the claim was made that reverse-temporal causality was demonstrated. Lewis dismisses this as nonsense (Time cannot go backward.) but makes no mention of advanced solutions to the wave equation that have been used successfully in both classical EM (Feynman & Wheeler, 1945) and the Transactional Interpretation of QM (Cramer 1986). (... to be continued).

Of course collapsing into "a particle" would never do to explain the phenomenon except the wave should so collapse at both slits to yield two particles, one for each hole. It is the diffraction, the interference pattern observed on the screen which shows that both slits have been penetrated by a wave. Would any suggest that such a wave collapse occurs at only one hole, while at the other it passes through as a wave? How then will the interference pattern be explained seeing there is no other wave to be interfered with, but only the path of an alleged particle instead. Thomas Young's sketch of the double slit diffraction pattern observed . . . http://en.wikipedia.org/wiki/File:Young_Diffraction.png As for the attempt to apply Schrödinger's wave mechanics to the double- slit diffraction anomaly, this was not Schrödinger's baby but that of Louis de Broglie with his "pilot wave" hypothesis which being proposed never came to anything mathematically sound. And as to what Schrödinger's opinion may have been on it, that may be out there, but for more on this specific topic current here today . . . http://groups.google.com/group/sci.physics/browse_thread/thread/6100aef7decc2148# -- JM

Hey, guy, time can't go backward (as far as we've observed and know). I would not call the use of advanced solutions to the wave equation "sucessful". While it is true that certain very interesting results have been obtained through theory sort of based upon this theory, those solutions are clearly "non-physical" and any application that tries to use them only APPROXIMATES them as best we can in normal time. Nobody that I know is currently making time travel successfully in reverse. The Lewis "guide wave" theory is especially interesting in that it makes the waves travel in a reverse direction rather than having time do so. In other words the waves are not from the source but from the detectors.

The classical equations of motion are time reversible (second order in the time derivative) but at our human level the chance of seeing this happen is slim to none. Similarly, the wave equation has two solutions at the micro-level. However, if you are a positivist you will believe that all reality only exists at the human scale or larger, so 'by definition' time-reversal is 'impossible'. Some of us do not put ourselves at the center of the universe. |
