The Limitations of Mathematics in Physics
The present philosophy in theoretical physics is to search for mathematical relationships that predict experimental results that are then used to verify the validity of the mathematics in defining our physical Universe, from the microcosmic to the macrocosmic. The philosophy was expressed succinctly by Dr. Hawking in Scientific American when he stated that he didn't care about "reality" because he didn't know what "reality" was, all that he cared about was whether the mathematics correctly predicted the results of experiment. Unfortunately, requiring that the results of observation and of mathematics be in agreement is NECESSARY BUT NOT SUFFICIENT in our study of the Universe around us. As a research tool, mathematics suffers from two basic limitations: A:- It is a linear logic process rather than an area logic process. Any error along the line of logic being used can easily propagate throughout the remaining logic chain without giving warning of its presence. (A solution using an area logic process, on the other hand, is similar to the solution of a crossword or jigsaw puzzle. An error made anywhere in such a process is revealed by an incongruity somewhere in the solution. As such, such a logic process is self-correcting because it forces one to go back and rethink the problem.) B:- The logic associated with the mathematical treatment of a process can lead to results in regions of the problem domain where another constraint is imposed by Nature. To a mathematically trained physicist such a constraint may well go unrecognized because it is not inherent in the mathematics. The existence of such a constraint may render the mathematical conclusions involved useless. The limitation described in paragraph A is illustrated by the by the derivation of the Lorentz Transformation for Transverse Force. Unlike the derivation of the Lorentz Transformation for Parallel Force that provides the correct result, the derivation of the Lorentz Transformation for Transverse Force is incorrect. (The derivation of this transformation is straightforward and is easily accomplished using the conventional Lorentz Transformations for Mass, Length and Time. The infamous "Right Angle Lever Paradox", see diagram http://members.aol.com/einsteinhoax/rf511.gif , provided a “common sense” warning that an error had been made in that mathematical derivation. In this diagram, if forces are applied at the ends of the right angle lever and the lever is observed not to rotate in both the "moving" and "stationary" reference frames, then the moments applied to each arm must be equal are equal in magnitude and opposite in direction in each of the reference frames. With the conventionally accepted values, the product of the Lorentz Transformation for Parallel Length and the alleged Transformation for Parallel Force is not equal to the product of the Lorentz Transformation for Transverse Length and the alleged Transformation for Parallel Length. This inequality implies that, if the torques applied to the arms are equal in one of the reference frames ("moving" or "stationary") they cannot be equal in the other reference frame ("stationary " or "moving") and the lever would then rotate in one of the reference frames and not the other. Since the lever does not seem to know of this requirement, it remains stationary, and it was necessary to reconcile the dilemma that resulted. One would think that rational men would accept that an error had been made in the derivation of the force transformations and search for that error. Instead, it was assumed that the derivation of the Lorentz Transformations for the Forces had to be correct, after all they were derived mathematically. To account for the difficulty, a convoluted explanation was devised which asserted that the rate of increase of energy in the transverse lever produced by the parallel force was balanced by the rate of increase of the angular momentum supplied by the torque difference between the two directions. The explanation conveniently ignored the fact that for moments to be applied to the lever by the forces applied to its ends, equal and opposite forces would result at the hinge pin. As a result, any energy that is added to the transverse lever arm by the applied parallel force at its end will be removed at the hinge pin, and the rate of change of energy in the lever is exactly zero. What was also ignored was the fact that the angular momentum of the lever is the product of its moment of inertia and its angular velocity. Since the lever was observed not to rotate in either reference frames, the rate of change of the lever's angular momentum is also zero. Properly done, the mathematical explanation amounts to the statement that 0 = 0. This is certainly true but is also meaningless. It is frightening that the advanced academic community could overlook such an error and appear in a large number of postgraduate level texts. It is even more frightening that individuals who would embrace such an explanation are in a position to teach our best and brightest. For a derivation of the correct Lorentz Transformations for Forces see http://www.members.aol.com/einsteinhoax/relcor.htm ). The type of error illustrated by paragraph B occurs in regard to the idea of "action at a distance" being produced by the exchange of "virtual particles". Mathematically, such particles are capable of providing both attractive and repulsive forces. In reality, in the absence of an overlying substrate for space (e.g.- the classical Aether or Dirac's "Sea of Negative Energy") with which the "virtual photons" could interchange momentum, the production by "virtual photons, of attractive forces acting at a distance would seem to be impossible. But then, if such a substrate exists, why do we need the concept of "virtual photons"? Perhaps it would be constructive to illustrate this type of limitation on the reliability of a purely mathematical treatment by considering the analysis of a conventional FET transistor circuit, the cascode. This circuit consists of two FET transistors with the drain of the first one driving the source of the second one and with the gate of the second biased at a constant positive voltage. For low frequency signals, the operation of such an amplifier is completely defined mathematically by a property known as "transconductance". The electron flow in the collector of the second FET is the product of the signal voltage applied to the gate of the first FET times the transconductance of the first FET. The mathematics tells us that a positive signal will produce a positive flow of electrons at the output and a negative signal will produce a negative flow of electrons at the output. What the mathematics doesn't tell us is that the process will not work unless there was a bias flow of electrons in the amplifier to which the output signal was added. With the bias current, the amplifier can produce both positive and negative electron flow signal outputs by adding to or subtracting from the bias current. Without the bias current, the amplifier can only produce positive electron flow outputs. The mathematics is NECESSARY BUT NOT SUFFICIENT to define the process. Similarly, the writer asserts that the mathematics associated with "virtual photons" is also NECESSARY BUT NOT SUFFICIENT. A substrate (e.g.- the classical Aether or Dirac's "Sea of Negative Energy" or one of the several "background energy of space" concepts) would seem to be necessary for the idea of "virtual photons" as a force carrier to work, but, if the substrate exists, why is the concept of "virtual photons" as force carriers required? Whether "virtual photons" exist can be evaluated by a rather simple experiment as shown in the figure at http://www.members.aol.com/einsteinhoax/cf43.gif . There is an even simpler means of evaluating the concept. A recent news item revealed that a loose oxygen cylinder was captured by the magnetic field of an MIR machine and flew across the room to crush the skull of a child being examined. If such a strong magnetic field existed in the room and that field involved "virtual photons", those photons would be sufficiently numerous to produce an amount of electromagnetic noise that would be easily measured. I doubt very seriously if such noise would be found if s search were made. Remember that Dr. Einstein warned "we have not proven that the Aether doesn't exist, we have merely proven we do not need it (for calculations). Also remember that it took 25 years of peer pressure to cause Dr. Einstein to relinquish the idea of "absolute time" (equivalent to believing the Aether) and accepting the unproven (and rather ludicrous) consensus viewpoint of space and time as a single entity. Theoretical physics has taken the easy position that only mathematics and experiment are required to deal with reality. Unlike every other branch of science, it is asserted that "mechanism" is irrelevant in physical theory. Since we live in the "mechanism" represented by our Universe, the prime goal of any responsible theoretician should be an understanding of the workings of that "mechanism" with the mathematical and experimental results used to iteratively improve our understanding of that "mechanization". What we have today, with the idea of "mechanism" eliminated, is more akin to group quasi-religious charlatanism (how many Angels can dance on the head of pin?) practiced by a controlling cadre of self promoting "scientists" than it is to an organized science.

Srettel15 resent the same drivel:
A:- It is a linear logic process rather than an area logic process. Any error along the line of logic being used can easily propagate throughout the remaining logic chain without giving warning of its presence. (A solution using an area logic process, on the other hand, is similar to the solution of a crossword or jigsaw puzzle. An error made anywhere in such a process is revealed by an incongruity somewhere in the solution. As such, such a logic process is self-correcting because it forces one to go back and rethink the problem.) Linear logic? Area logic? Who does this idiot think he is kidding? To him linear logic is obviously anything he does not like while area logic is anything he does like. What a turkey. As any book on logic will tell you logic is what necessarily follows for the premises by the rules of logic. We all have a pretty good intuitive ideas what they are and they are not divided into linear or area. Sick of reading this crap. Bill |

What a turkey. As any book on logic will tell you logic is what necessarily follows for the premises by the rules of logic. We all have a pretty good intuitive ideas what they are and they are not divided into linear or area. Robert J. Kolker correctly wrote: For sure, the rules of logic that scientists and mathematicians use are well known and quite rigorous in their application. But one thing logic will NOT tell you, is what to assume in the first place! What are the sources of fruitful scientific hypotheses? It is not combing over vast heaps of facts to come up with an inductive hypothesis, although this sometimes happens. Good theories and hypotheses do not leap out of piles of act, as did Athena from the Brow of Zeus. The process by which hypothesis are made was studied by the American logician, philosopher and mathematician Charles S. Peirce. He called the process abduction (nothing to do with kidnapping!) as opposed to induction. No, there are no algorithmic or mathematical rules by which one can come up with the best hypothesis proposing causes to a given set of effects. This, like mathematical creativity is based on subconscious processes and intuition. That is what makes theory formation an art as well as a discipline. Here is an example: the equivalence principle, which Einstein called the happiest thought of his life. It is an abduction which characterizes gravitation and leads to the hypothesis that gravitation is an effect of spatial transformation by the presences of mass. A bend in the manifold, as it were. The is no logical necessity for this hypothesis and others have proposed covariant theories of gravitation using forces that do almost as well as GTR. Einstein asked a key -question-. Is there a difference between being in an elevator (or a uniformly accelerated vessel in space) and being subject to a uniform gravitational field. The answer, in the small, locally, as that one cannot determine the difference. From this question follows the geometry of spacetime. Others might have asked the question -- how do we modify Newton's law to account for certain well known gravitational effects, such as the precession of the perihelion of Mercury, for example. So there is an area of -thought- that leads to winning hypothesis, that is not entirely algorithmic or mechanical. But this area is -not- deductive logic. Deductive logic is still as rigorous and rule based as ever. There does not appear to be a surefire mechanical method that can be programmed on a computer, that will produce the best hypotheses. Just as there is no computerizable algorithmic methed for telling a mathematician -what theorems- are important. From a purely formal and logical point of view all theorems are equal, but we know from experience that some theorems are more important to prove than others, because in seeking the proof, other areas of mathematics are opened up. The quest for Fermat's (so-called) Last Theorem (which was really a conjecture on his part) is a good case in point. In the area of mathematics, fruitful conjectures are the counterparts to fruitful hypotheses in physics. Deduction uses logic - induction uses creativity. Absolutely necessary but it is not logic.
