Sunday 11 October 2020

Braindead Sunday. Waiting for the spark. Deadly bored. The price I pay for having a good idea yesterday? Once again proving that trying hard to have ideas is not much more productive than trying hard to win a lottery. Maybe my mind thinks I know all I need to know and I should get on with a bit of writing, but I am too lazy to force myself to do things.

Back to st06_constructing_world and continuing to search for the physical meaning of quantum mechanics, much of which I imagine to be incorporated in the space-time / momentum energy statement of the so called uncertainty principle which I prefer to call the principle

[page 224]

of limited resolution. Δx.Δp ≈ ΔE.Δt ≈ h The fact that this appears in two forms in space-time points (to me) to a bifurcation whose underlying symmetry is the distinction between kinetic and potential energy which seem to be the first or second break after actus purus. In space time act comes through as ML2T-1 and energy as ML2T-2 in which we might replace M by E/c2 . . . which is just action again, so did this little circle reveal anything?

Copenhagen Wikipedia: ' The Copenhagen interpretation denies that the wave function provides any directly apprehensible image of an ordinary material body or a discernible component of some such, or anything more than a theoretical concept.' Copenhagen interpretation - Wikipedia

Carl Friedrich von Weizächer: 'while participating in a colloquium at Cambridge denied that the Copenhagen interpretation asserted "What cannot be observed does not exist". Instead he suggested that the Copenhagen interpretation followed the principle "what is observed certainly exists; about what is not observed we are still free to make suitable assumptions; We use that freedom to avoid paradoxes.

" The domain of the wave function is configuration space [Hilbert space] an abstract object quite different from ordinary physical spacetime. At a single "point'" of [infinite dimensional] configuration space the wave function collects probabilistic information about several distinct particles that respectively have space-like separation. So the wave

[page 225]

function is said to supply a non-seperable representation".'

Heisenberg: 'Of course the introduction of the observer must not be understood to imply some kind of subjective features are to be brought into the description of nature. The observer has rather, only the function of registering decisions, ie processes in space and time, and it does nit matter whether the observer is an apparatus or a human being; but the registration, ie the transition from the "possible to the actual" is absolutely necessary here and cannot be omitted from the quantum theory.' Werner Heisenberg: Physics and Philosophy: The Revolution in Modern Science, p 137

Weinberg 'The Copenhagen interpretation describes what happens when an observer makes a measurement but the observer and the act of measurement are treated classically. This is surely wrong: Physicists and the apparatus must be governed by the same quantum mechanical rules that govern everything else in the universe. But these rules are expressed in terms of a wave function (or more precisely a state vector) that evolves in a perfectly deterministic way [lossless codec, ie turing machine]. So where do the probabilistic rules of the Copenhagen interpretation come from? . . . It is enough to say that neither Bohr nor Einstein had focussed on the real problem of quantum mechanics. The Copenhagen rules clearly work, so they must be accepted. But this leaves the task of explaining them by applying the deterministic equation for the evolution of the wave function., the Schrödinger equation, to observers and their apparatus.' Steven Weinberg: Einstein's Mistakes

The obvious answer (to me) is a combination of fixed point

[page 226]

theory, halting computation and the random interruptions of machines in a network, putting them on a new trajectory whose point of halt in one of the eigenfunctions embedded in the nature of the interacting particles. The image of the spinning die being interrupted and observed by the table [upon which is falls] seems appropriate.

Energy has two roles, gravitation and quantum mechanics. Quantum mechanics looks at the fine structure of energy built round the quantum of action. Gravitation looks at the broad structure, treating the flow of energy as a power network wired in 4D without crossing, the most complex flows being described by the Riemann tensor [understood as we understand quantum hamiltonians] in which differentials between components measure the orthogonal / linear / independent flow rates. How does energy connect to a) the shape of space? - by orthogonality; how does it connect to quantum mechanics? by computation and by tuning / superposition. So we distinguish superposition from orthogonality. Lanczos tensor - Wikipedia

Having identifed the initial singularity, actus purus and the classical god, the next step is to see how closely we can

[page 227]

attribute the classical properties of god with the quantum of action, following step by step through the prima pars of the summa. This is the task for section 6.2, treating briefly of existence, simplicity, perfection, goodness, infinity, de existentia in rebus, immutability, eternity, unity, knowledge, ideas, truth, life, love, justice and mercy, providence, power, beatitude, and then to the trinity as the archetype of the creation of the universe within god by procession and communication, generating the transfinite network. Here we study how the quanta of action learn from each other, generating the language of love like the spirit by their own interaction. Thomas Aquinas, Summa, I, 2, 3: Does God exist? et sqq.

Next step: how does the baby universe grow the shape of general relativity? Is quantum mechanics a prerequisite? Is it a web of rapidly reproducing quanta of action? Do we need fermions and bosons? The graviton is a boson. What is the corresponding fermion? What is the smallest sample of differentiable manifold that we can make [Riemann?]?

When we apply group theory to particle physics we assume that the group is in some way embodied in the particles as, for instance, the group SU(3) is embodied in the quarks. What we are wanting to say is that this embodiment is the representation of a certain turing machine (piece of software) in a quantum of action that acts as commanded by the software, thus playing its role in the group. So what is the gravitational group, and how is it shared among a swarm of quanta?

[page 228]

Looking for a logical foundation of the universe. 1. copying of quanta of action. 2. Time division multiplexing = energy. 3. bosons. 4. space division multiplexing - fermions. 5. Independent existence means independent form = {intrinsic, environmental}. 6. multiplication of quanta opens the way to potential energy → variation / selection. 7. logical processing by contact, not, and, or, so we are thinking in terms of logical pieces fitting together as we fit them in our minds. In mathematics the mathematical mind is the representation of the logic; in reality the logical structure embedded in the particle is the representation and a process occurs when two quanta communicate just as a mathematical argument proceeds by the meeting of the elements in an abstract turing machine played out in a human mind. So we base the whole universe on the axioms of set theory + the axioms of logic.

Now let us turn to the millennium prize for Quantum Yang Mils Theory and try to apply the ideas above. Can I trust myself when I get excited? The thoughts I am trying to capture logically point to the first couple of cycles of development in the evolution of the universe from the pure initial singularity. I am in effect coming in at the front (back) door when all the high energy physicist are coming in from the back (front) door. The first job is to make a couple of k on the market. Carlson, Jaffe & Wiles: The Millennium Prize Problems page 129 '1. The Physics of Gauge Theory.'

[page 229]

' classical notions, such as "the trajectory of a particle" do not apply. Because we are talking about logical events that are prior to spacetime.'

Fields: may simply be proxies for the interaction of particles in contact, eg Maxwell, Einstein. 'Since fields interact with particles, it became clear by the late 1920s that an internally coherent account of nature must incorporate quantum concepts for fields as well as particles.' Why? Fields are invisible, but this may be a consequence of the invisibility theorem and be explained by the logical operations of embodied software http://naturaltheology.net/Development/Dev02_Model/model06Invisibility.html

' The distinction between fields and particles breaks down since the Hilbert space of a quantum field is constructed of particle-like excitations. Conventional particles, such as electrons are reinterpreted as states of a quantized field.' ie (I would say) quanta of action [in which are embedded code corresponding to the nature of the particle we are talkng about].

Anti particles – open the way to creation and annihilation, and we see conservation of energy as the conservation of matter in the Aristotelian sense: nec quid, nec quale, nec quantum, nec aliquid eorum quibus ens determinatur [neither what, now what sort nor what amount, nor anything of the properties by which being is determined].

Nobel Prize: 'covariant and gauge invariant formulations of QED that allow computations of observables at any order of perturbation theory.' Feynman, renormalization, hocus pocus [inspired by Dirac: “It seems that some essentially new physical ideas are here needed.” 'At any rate, I believed that the difficulty arose somehow from a combination of the electron acting on itself and the infinite number of degrees of freedom of the field.'].

a) Feynman diagrams operate in spacetime
b) more complex diagrams make smaller contributions

In full QED ' There is a possibility that an electron at A or a photon at B, moving as a basic action to any place and time in the universe'.

That includes places that can only reached at speeds greater than than that of light and also earlier times (An electron moving backwards in time can be viewed as a positron moving forward in time.) [more hocus pocus?].

Propagators are essentially solutions to the Dirac equation (electron) and Maxwell's equation (photon).

Infinite probability amplitudes arise from self energy = not unitary.

Mathematical formulation. Peskin & Schroeder: An Introduction to Quantum Field Theory, p 78

Why is this so? Are these fictions real? It seems unlikely. They are a product of the two contradictory notions that on the one hand quantum processes exist prior to space and on the other hand that space-time is the domain of QED and so gives us an infinity of loops of possibly infinite energy. One way to deal with this is to replace continuous parameters with digital logic, a process slowly oozing ahead in the conceptual world.

From algorithmic information point of view Dirac and Maxwell's equations do not tell us much and then we have to add thousands of Feynman diagrams and propagators to get an accurate answer. What if we filled all the particles with turing machines and linked them into gigantic network, we could make a complex system out of simple pieces?

What, for instance, is the code f0r asymptotic freedom? Maybe

it is very easy to build within the spacetime operating system. I seem to have the same block here trying to make computational physics as I faced when I began to try to write software.

Writing is at a standstill while confidence is building in the creative approach I hypothesize for the universe to build itself, seeing parallels between the discoveries of high energy physics and the early days of the logical evolution of the universe. The parallel between creation and the development of the mathematical community seems to be growing clearer and the promise of a consistent logical approach to the complexification of action seems to be showing some daylight around the difficulties currently induced in quantum field theory by the historical burden of analytically continuous mathematics that became entrenched in the nineteenth century. [This] has yet to be fully exorcised by the logical and quantum development of the twentieth century, all played out against the background of overly simplistic and politically naive authoritarian religion, which is currently (I hope) enjoying its last gasp. Thinking about no 7 of the millennium prize problems, I feel more strongly the need to go back to logical continuity after we have been led into a lot of ad hocery to make the very narrow complexity of continuous mathematics do the job of modelling the pure intelligence of the universe. The US election is bringing this confrontation between fundamentalist religion and creative excitement into sharp focus, since of the big three authoritarian countries, China, Russia and the current US, [US] is the only one that can save itself.

Saturday 17 October 2020

Although I have been thinking my approach to particle physics (where 'particle' means any independent entity) is a long way from the current standard, the more I think about the two pictures the more they appear to converge and the more timid confidence I am beginning to feel in the logical quantum of action / turing machine model I have been on for years. So I hope that in the end I will congeal on something that looks credible in the eyes of both physicists and theologians, which is the aim. My present impasse in the relationship between quantum mechanics and gravitation may also have a germ of a solution in section 3.4.2 of my thesis. Jeffrey Nicholls: Prolegomenon to Scientific Theology, 3.4.2

Introduction of gauge theory: ' In field theories, different configurations of the unobservable fields can result in identical observable quantities. A transformation from one such field configuration to another is called a gauge transformation. The lack of change in the measurable quantities is called a gauge invariance. . . . Since any kind of invariance under a field transformation is considered a symmetry, gauge invariance is sometimes called gauge symmetry. . . .. Over the course of the 20th century physicists gradually realized that all forces (fundamental interactions) arise from the constraints imposed by local gauge symmetries, in which case the transformations vary from point to point in space and time. . . . Gauge theories constrain the laws of physics because all the changes introduced by gauge transformations have to cancel each other out when written in terms of observable quantities. Introduction to gauge theory - Wikipedia

[page 236]

Gauge theory assumes that there is a lot going on that is not really happening, that is that it is not really represented in a physically observable way. This plethora of events is caused by the use of continuous mathematics on the assumption that it represents an infinite amount of information when in fact it represents [almost] nothing at all [really just the information content of the written equations and their tacit mathematical background].

This all comes from the decision to use artificial frames of reference that have no natural connection to the systems being studied, which go about their business through their internal relationships without reference to any external system. The tensor calculus that we use to honour the fact that reference frames are useless adds a lot of useless discussion of transformation which are more talk about the artificial reference frames than reality. This in turn is the result of trying, like Newton, to achieve a god's eye view of reality rather than the natural subjective view.

Invisibility is not caused by the absence of representation but by the invisibility theorem (see above). Everything real is physically represented. Even spiritual and metaphysical notion are represented by human brain states. Representation means that all physical states are locally finite and not [geometrically] continuous.

A Night at the Louvre: Leonardo da Vinci Louvre

The "mathematical field" in the mathematical community exists in the minds of the mathematicians and their communications. The mathematicians are the fermions and the communications are the bosons. How do we model these as a local gauge symmetry? One point to note

[page 237]

is that given all the human languages that may be involved each core mathematical idea may have a large space of expressions which can be translated [transformed] into each other by the usual process of human communication. The advantage of the turing machine approach coupled with the idea of lagrangian, stationarity and invariance means that at least in simple cases we can arrive at a canonical proof which we might find reflected in nature.

We may think of mathematicians as particles and sources and use symmetry with respect to complexity to "intrapolate" down to fundamental particles.

Obtaining numerical precision (by renormalization and other hocus pocus) at the cost of logical consistency might be a mistake.

How do quanta of action evolve / learn from each other so becoming more complex? Evolution requires some sort of memory which means states that have longer lives than others which is a consequence of reducing energy / frequency [so that higher slower layers (like genes) control the states of lower faster layers (individuals)] so this reducing energy /increasing complexity [are self consistent]. So how do quanta of action exploit this process to create language like children learn. Potential is the final cause, attracting creation out of nothing [by arranging pre-existing parts / quanta like a jigsaw]. We take the foundation of all this from the trinity. The spirit is the language [boson] that father and son share as a consequence of their common descent [so maybe the son is slower than the father and so controls them].

Jaffe & Witten page 130: 'The massless nature of classic Yang-Mills waves was a serious obstacle to applying the Yang-Mills to other forces, for the weak and nuclear forces are short range and many of the particles are massive.' ie massive bosons, W, Z.

Jaffe & Witten page 131: Problem (somewhat) solved by Glashow-Salam-Weinberg electroweak theory with Higgs to give mass. One day I might understand this. Have a look at Shapiro/ Marjorie Shapiro: Physics 226: Particle Physics: Lectures 1 - 28

For strong force masslessness solved by "asymptotic freedom".

Quarks are SU(3) electrons.

'For QCD to describe the strong force we need:

.

'(1) "Mass gap", ie every excitation of vacuum needs energy Δ > 0

'(2) "quark confinement" means individual SU(3) quarks form an SU(3) invariant unit like proton and pion.' Ie quarks form a closed system so they are not independently represented.

page 132: '(3)"chiral symmetry breaking" which means 'the vacuum is potentially invariant (in the limit that the quark masses vanish) only under a certain subgroup of the full symmetry group that acts on the quark fields. ' (?) Vacuum state, QCD vacuum. Sounds a bit like rubbish, see cosmological constant problem: Wilczek, expectation value. Vacuum state - Wikipedia, QCD vacuum - Wikipedia, Expectation value (quantum mechanics) - Wikipedia, Frank Wilczek: The Lightness of Being: Mass, Ether, and the Unification of Forces page 109

A corecipient of the 2004 Nobel Prize in Physics, Wilczek knows what he’s writing about; the question is, will general science readers? Happily, they know what the strong interaction is (the forces that bind the nucleus), and in Wilczek, they have a jovial guide who adheres to trade publishing’s belief that a successful physics title will not include too many equations. Despite this injunction (against which he lightly protests), Wilczek delivers an approachable verbal picture of what quarks and gluons are doing inside a proton that gives rise to mass and, hence, gravity. Casting the light-speed lives of quarks against “the Grid,” Wilczek’s term for the vacuum that theoretically seethes with quantum activity, Wilczek exudes a contagious excitement for discovery.

In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false, One is thus led to conclude that the description of reality given by the wave function is not complete.' back

The problem of defining symmetry is an interesting one and we have already noted that Weyl gave a good definition, the substance of which is that a thing is symmetrical if there is something we can do to it so that after we have done it, it looks the same as it did before. For example, a symmetrical vase is of such a kind that if we reflect or turn it, it will look the same as it did before. The question we wish to consider here is what we can do to physical phenomena, or to a physical situation in an experiment, and yet leave the result the same.' back

Feynman, Leighton & Sands FLP III:07, Chapter 7: The Dependence of Amplitudes on Time, 'We want now to talk a little bit about the behavior of probability amplitudes in time. We say a “little bit,” because the actual behavior in time necessarily involves the behavior in space as well. Thus, we get immediately into the most complicated possible situation if we are to do it correctly and in detail. We are always in the difficulty that we can either treat something in a logically rigorous but quite abstract way, or we can do something which is not at all rigorous but which gives us some idea of a real situation—postponing until later a more careful treatment. With regard to energy dependence, we are going to take the second course. We will make a number of statements. We will not try to be rigorous—but will just be telling you things that have been found out, to give you some feeling for the behavior of amplitudes as a function of time.' back

Feynman, Leighton & Sands FLP III:08, Chapter 8: The Hamiltonian Matrix, 'One problem then in describing nature is to find a suitable representation for the base states. But that’s only the beginning. We still want to be able to say what “happens.” If we know the “condition” of the world at one moment, we would like to know the condition at a later moment. So we also have to find the laws that determine how things change with time. We now address ourselves to this second part of the framework of quantum mechanics—how states change with time.' back

Gauge theory - Wikipedia, Gauge theory - Wikipedia, the free encyclopedia, ' In physics, a gauge theory is a type of field theory in which the Lagrangian does not change (is invariant) under local transformations from certain Lie groups. The term gauge refers to any specific mathematical formalism to regulate redundant degrees of freedom in the Lagrangian. The transformations between possible gauges, called gauge transformations, form a Lie group—referred to as the symmetry group or the gauge group of the theory. Associated with any Lie group is the Lie algebra of group generators. For each group generator there necessarily arises a corresponding field (usually a vector field) called the gauge field. Gauge fields are included in the Lagrangian to ensure its invariance under the local group transformations (called gauge invariance). When such a theory is quantized, the quanta of the gauge fields are called gauge bosons. If the symmetry group is non-commutative, then the gauge theory is referred to as non-abelian gauge theory, the usual example being the Yang–Mills theory. ' back

Gerard 't Hooft, Dimensional Reduction in Quantum Gravity, 'The requirement that physical phenomena associated with gr avitational collapse should be duly reconciled with the postulates of quantum mec hanics implies that at a Planckian scale our world is not 3+1 dimensional. Rather, th e observable degrees of free- dom can best be described as if they were Boolean variables de fined on a two-dimensional lattice, evolving with time. This observation, deduced fro m not much more than unitarity, entropy and counting arguments, implies severe restrictio ns on possible models of quantum gravity. Using cellular automata as an example it is argued t hat this dimensional reduction implies more constraints than the freedom we have in constru cting models. This is the main reason why so-far no completely consistent mathematic al models of quantum black holes have been found.' back

This mechanism implies the existence of the Higgs boson. The boson's existence was confirmed in 2012 by the ATLAS and CMS collaborations based on collisions in the LHC at CERN. On December 10, 2013, two of the physicists, Peter Higgs and François Englert, were awarded the Nobel Prize in Physics for their theoretical predictions.

Hodge star operator - Wikipedia, Hodge star operator - Wikipedia, the free encyclopedia, ' In mathematics, the Hodge star operator or Hodge star is a linear map defined on the exterior algebra of a finite-dimensional oriented vector space endowed with a nondegenerate symmetric bilinear form. Applying the operator to an element of the algebra produces the Hodge dual of the element. This map was introduced by W. V. D. Hodge. For example, in an oriented 3-dimensional Euclidean space, an oriented plane can be represented by the exterior product of two basis vectors, and its Hodge dual is the normal vector given by their cross product; conversely, any vector is dual to the oriented plane perpendicular to it, endowed with a suitable bivector. back

Introduction to gauge theory - Wikipedia, Introduction to gauge theory - Wikipedia, the free encyclopedia, 'A gauge theory is a type of theory in physics. Modern theories describe physical forces in terms of fields, e.g., the electromagnetic field, the gravitational field, and fields that describe forces between the elementary particles. A general feature of these field theories is that the fundamental fields cannot be directly measured; however, some associated quantities can be measured, such as charges, energies, and velocities. In field theories, different configurations of the unobservable fields can result in identical observable quantities. A transformation from one such field configuration to another is called a gauge transformation;[ the lack of change in the measurable quantities, despite the field being transformed, is a property called gauge invariance.' back

The fallout for Rio Tinto has been profound as has the groundswell of criticism of Western Australia’s outdated heritage laws. A path forward must ensure a pivotal role for Indigenous communities and secure Keeping Places for heritage items. More broadly, we need more Indigenous places added to the National Heritage List, ensuring them the highest form of heritage protection.

Experiments with ‘anti-political’, direct-action social networks are flourishing. In some quarters, voting is judged a worthless waste of time, money and energy. And more than a few democracies are shaped by what can be called the Philippines syndrome: a strangely contradictory trend marked by elections that come wrapped in intense media coverage and great public excitement mixed with bitter disappointment about the sidelining of elected governments by big banks, big money and the outsourcing of state functions to cross-border power chains. The feeling that elections are pointless manipulations by the rich and powerful finds its nadir in the whole phenomenon of ‘electoral despotism’ in Russia, China, central Asia and elsewhere: the use by oligarchs of periodic elections as an instrument for consolidating arbitrary power.' back

That we are now happily contemplating locking up 14-year-olds on suspicion (not proof) of what they may otherwise do is just a fascinating reflection of how far we've come.
