The concept of electron "spin" is basic to any quantum mechanics course, but what exactly is spinning is never made clear. Wolfgang Pauli, one of the concept's originators, initially rejected the idea because if the electron was to have a finite radius, as indicated by certain experiments, then the surface would be spinning faster than the speed of light. On the other hand, if one regards the electron as a point particle, as we often do, then it is truly challenging to conceive of a spinning top whose radius is zero, not to mention the aggravation of infinite forces"<br /><br />Then he attacks the 2-slit experiment:<br /><br />"....Rather than describing how the light interacts with the slits, thus explaining why it behaves as it does, we merely demand that the light wave meet certain conditions at the slit edge and forget about the actual forces involved. The results agree well with observation, but the most widely used of such methods not only avoids the guts of the problem but is mathematically inconsistent"<br /><br />He goes on and on...attacking Lagrangian mechanics, ....etc<br /><br />"The great swindle of of introductory physics is that every problem has an exact solution.

His unitary field theory of 1936–39 nonetheless<br />anticipated several features of modern grand-unified theories, and contained<br />Yukawa’s theory as a particular case. The tools he developed in this earlier<br />period permitted his and his collaborators’ post-war progress on renormalized<br />quantum electrodynamics, including important results on regularization,<br />causal Green functions, and S-matrix theory. Had these results been<br />expressed in a form as seductive as Feynman’s, Schwinger, and Tomonaga’s,<br />and Freeman Dyson’s contemporary writings, Stueckelberg would be more<br />often recognized as a central figure of this extraordinary episode of the history<br />of physics."<br />...<br /><br />"Now,<br />we do not think that the value of Feynman’s fabulous contribution to physics<br />is in any way diminished by the historical fact that Stueckelberg had already<br />come up with the classical and quantum interpretation of an antiparticle as a<br />particle going backwards in time. With hindsight, one can only lament that<br />Stueckelberg’s papers, published during the war in French in a journal of neutral<br />Switzerland, did not receive the attention they should have merited."<br />....<br /><br />"In<br />general, Stueckelberg’s style, language and choice of journals did not favour<br />the propagation of his ideas. He was quite isolated and his work progressed<br />in parallel with those of celebrities like R. P. Feynman, J. Schwinger and S.<br />Tomonaga. These circumstances explain why Stueckelberg’s contributions<br />are so little known and may seem marginal. It is, in fact, unquestionable that<br />some of his findings have a deep and lasting importance, such as his showing<br />that collision processes cannot be understood if their causal time evolution is<br />ignored."<br /><br />PHYSICS: Its not what you know but its who you know and how its presentedAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-88015571118592391672014-08-08T22:02:07.663-07:002014-08-08T22:02:07.663-07:00Ensemble interpretation conjured up by Popper and ...Ensemble interpretation conjured up by Popper and supported by Einstein.

In principle one can compute the structure of oil<br />molecules and work out the way these molecules interact<br />among themselves in bulk oil and thence go on to the viscosity<br />of oil. But a completely detailed calculation that traverses<br />the whole route from the individual molecule and its ingredients<br />all the way up to the astronomical number (about 10E24) of<br />molecules present in even a small drop of oil is utterly unthinkable.<br />The single molecule is already complicated enough. Thus,<br />approximations and aggregate treatments have to be adopted<br />along the way, relying on various rich and active fields of scienti<br /> c inquiry; for example, the fi eld of statistical mechanics. A<br />pumper who wants highly accurate predictions of flow rate is<br />well advised to adopt the empirical value of viscosity. But that<br />same pumper may also share with others a curiosity about why<br />things are the way they are. Moreover, there is the possibility<br />of learning enough at the microscopic level to design molecular<br />additives that can alter the viscosity in wanted directions."<br /><br />Imagine, trillions of dollars of "molecular additives", coatings, etc that do not work as advertised and are deliberate fabrications (fraud). Thats the purpose of string theory.. passing off bogus science and engineering in the small as legitimate to reap obscene profits. And non observable because I bet they imbed their all subsuming "Grand Theory of Everything" into a hocus pocus "quantum" (remember String theory is more fundamental than quantum mechanics) processor run by Google. If you say "string theory is garbage" but its so big that you cannot understand it all then you lose.<br /><br />Of course this is tin foil hat stuff.

The Relative-state and Many-worlds interpretation<br />7. The Quantum-logical interpretation<br />8. The Hidden-variable interpretation<br />9. The Stochastic interpretation<br /><br />According to Sudbery, Bohr's interpretation is strongly expressed by the Minimal interpretation. He sure gives Bohr a good tongue lashing too:<br /><br />"Moreover, it cannot be true that the sole purpose of a scientific theory is to predict the results of experiments. Why on earth would anyone want to predict the results of experiments? Most of them have no practical use; and even if they had, practical usefulness has nothing to do with scientific inquiry. Predicting the results of experiments is not the purpose of a theory, it is a test to see if the theory is true. The purpose of a theory is to understand the physical world"<br /><br />Sudbery is of the opinion that "No one interpretation is generally accepted" including the Copenhagen which he believes has been applied to at least four different interpretations listed above.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-33692894683718950152014-08-08T12:33:01.790-07:002014-08-08T12:33:01.790-07:00The confusion continues:

"That, in a nutshell, i...From Evert Jan Post:<br /><br />"That, in a nutshell, is how Hilbert space and its spectral properties became<br />the realm of reality for the Twentieth Century physicist, almost to the<br />exclusion of spacetime itself. Fortunately, the representation theory of<br />groups retained a last powerfullink between spacetime and Hilbert's configuration<br />space of quantum states. The group theoretical method was a<br />last concession to a phenomenology of microphysical symmetry.<br />Somehow, and again ironically, symmetry had been permitted to penetrate<br />the fog of uncertainty shrouding microphysical structure. Weyl and<br />Wigner had shown the way.<br />The emergence of macroscopic quantum effects, however, brought us<br />back from the abstract multi-dimensional Hilbert spaces into a reality of<br />more intuitive spacetime model-making. Over and above symmetry, the<br />mathematical machinery instrumental for implementing greater balance<br />between formal and intuitive procedures in physics must be expected to<br />call, more than be fo re , on the topology-oriented studies initiated in<br />mathematics by Poincare, Brouwer, Hopf, de Rham, and Hodge.<br />A recognition of this new impending reality has been very difficult for<br />physics. For more than half a century, it has preached the gospel of a<br />quantum mechanics, in which Hilbert space became almost a sole storage<br />place of fundamental physical truth. Those involved in the study of quantum<br />mechanical fundamentals have been brushing up Hilbert space formalisms,<br />using group theoretical methods for finding out more about the<br />spacetime structure of the objects gene rating the Hilbert space superstructures.<br />There is, at this time, no real acceptance of a need to complement<br />this procedure with intuitive conjecture by following in both directions the<br />threads of logic interconnecting suspected cause and perceived effect.<br /><br />attitude is understandable in an interpretational atmosphere, which, as a result<br />of its own premises, had been forced to restriet the rules of causality in<br />the microdomain.<br />While the use and function of Hilbert space, as it now stands, is not to<br />be underestimated, its primary role is instrumental for ensembles, not for<br />single systems! The Hilbert integral equation as definer of eigenvalue situations<br />has an ensemble connotation, because it defines the wave function<br />W in any point in terms of W everywhere else through the process of<br />integration in the physical domain (chapter XVII;8).<br />The Hilbert integral equation as Schroedinger equivalent has an<br />inherent "smeared-out plurality" wh ich seems out-of-context for a single<br />system. The period integral assessment, by contrast, does not have this<br />reflexive interconnectedness of its spatial parts, which is so characteristic<br />of the Schroedinger plurality. The period integral's domain of integration<br />can be shrunk unto the single (microphysical) object of observation. It is<br />capable of exploring topological structure, where Schroedinger's process is<br />confined to essential physical features of the ensemble constituents only.<br />This inability of making an adequate ensemble versus single-system<br />distinction led quantum mechanics into the dead-end street of formal abstraction.<br />This escape in abstraction became misleadingly acceptable.<br />Getting out of this dead-end situation, the man-made fog of "uncertainty"<br />needs to be lifted so that horizons become visible again. After that, a view<br />of the single-system domain comes into focus, thus opening up a potential<br />for the more intuitively oriented methods of topological modelling in<br />actual spacetime, not Hilbert space! There is presently, at best, a general<br />but vague awareness of the nature of these deficiencies in contemporary<br />quantum mechanics. The existing situation of a long standing status quo<br />reveals physics' reluctance in coming to grips with the cited predicament.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-57830304463541728632014-08-08T10:46:44.660-07:002014-08-08T10:46:44.660-07:00From the Evert Jan Post book:
"If no thing e...From the Evert Jan Post book:<br /><br />"If no thing else, the reprogramming shows that properly chosen ensemble<br />specifications bring the Popper proposition into a revealing quantitative<br />relationship with the Schroedinger equation. While this fact still does not<br />establish beyond a shadow of a doubt that the Schroedinger equation is an<br />ensemble tool, it does make the ensemble option a good deal more probable<br />than the single-system option. As a remaining restraint preventing an allout<br />support of the ensemble option, one should consider that even these<br />explicit quantitative relations between ensemble statistics and Schroedinger<br />results still fall short of aiding in a complete derivation of the Schroedinger<br />equation from first principles.<br />In fact, considering the lacunar nature of the derivational origin of the<br />Schroedinger equation, there should be real doubt whether this equation<br />will ever be derivable from first principles. After all those years of investigation<br />and contemplation, it is more likely that Herman Weyl's words are<br />to be taken more literally than ever intended: the Schroedinger equation's<br />relation to Hilbert space was (and still is) "afavor offortune."<br />With all reservations in place, it is thus concluded that the Schroedinger<br />equation comes conceivably closest to describing dilute ensembles of<br />identical single systems in quantum states that are randomized in phase and<br />orientation. The word "conceivably" here conveys that there is no proof by<br />derivation to completely substantiate this statement. All of this indicates<br />that there is no known context for which the Schroedinger equation can be<br />given a status of absolute physical exactness. The many statements to the<br />contrary in the quantum mechanical textbook literature, therefore, are to<br />be regarded as the products of wishful thinking.<br />Overwhelmed by the equation's unparalleled success, earlier theorizing<br />had always tacitly assumed an absolute and exact status for quantum mechanics'<br />major tool of inquiry. Physical imagery kept drifting around on<br />this magic cloud, which had brought so much "fortune" beyond what<br />physics had deserved on the basis of "merit." Hence, when the Copenhagen<br />interpretation became available as an intellectual vehicle for consolidating<br />this equation's position of "fortune," the Copenhagen view automatically,<br />yet unjustifiably, assumed the same aura of near-perfect truth that had already<br />been identified with the Schroedinger equation and spectral theory.<br />Now, in retrospect, physics should have had some real doubts that such a<br />lofty assignation, even for the Schroedinger equation, might not be on<br />altogether solid grounds.<br />In the course of this reprogramming, evidence has been compiled which<br />amply supports the Popper-ensemble proposition in conjunction with a required<br />phase-and-orientation randomness of its constituent elements. It is<br />the best that can be done for the Schroedinger equation, which, incidentally,<br />is a lot better than what the textbook literature has done for the mutual<br />relation of the Schroedinger equation and the single system. The textbook<br />method simply postulates an interrelation between single-system and<br />Schroedinger equation, and then, depending on Copenhagen-related convictions,<br />this premise is made "plausible" with mystifying statistical considerations,<br />which, until this day have not found their "universe of discourse.
