What have I got to say on the chromodynamics page? (page 24: Quantum chromodynamics: QCD). Plod along with the introduction and history and then atempt to make a criticism of the current theory in the light of my placement of Hilbert space prior to Minkowski space and find some light on asymptotic freedom from this point of view. We are looking at a network of three quarks and three gluons inside a hadron and trying to find a cause of asymptotic freedom which does not depend on renormalization and take advantage of the Turing vacuum introduced on page 23: Quantum field theory This seems to be impossible, but I like to relax myself by feeling that another month spent perfecting pages 23, 24 and 25

[page 352]

would be well spent. Now may be the time to send page 22_gravitation to Rovelli [who, it seems, has no time to listen].

Some points for cc24_chromodynamics from Wilczek The Lightnesss of Being. Frank Wilczek (2008): The Lightness of Being: Mass, Ether, and the Unification of Forces

Wilczek page 1, Part I: The Origin of Mass: 'Matter is not what it appears to be . . . [a persistent refrain from the physics popularizers, see Rovelli ref below] The mass of ordinary matter is the embodied energy of the basic building blocks, themselves lacking mass. Nor is space what it appears to be . . . [it] is revealed in our minds as a compolexc mechanism full of spontaneous activity'. See Wilczek page 109: total [computed density of universe as a factor of its observed density 1044 → 10100+ or so, the cosmological constsant problem, pure theoretical rubbish.

page 4: 'Devices to enhance our senses reveal a richer world . . . but the ultimate sense-enhancing device is the thinking mind' or an uncontrolled imagination.

page 6: 'The deep strucutre of the world is quite different from its surface structure.' The physicists are as far off as the theologians.

page 9: 'The scientific soul of matter, its irreducible essence, was mass'.

The new theory sees a world based on a multiplicity of space filling ethers, a totality I call the Grid. The new world model is extremely strange, but also extremely successful and

[page 353]

and accurate ' to the order of 10±50 [See also Carlo Rovelli (2017): Reality is Not What it Seems: The Journey to Quantum Gravity]

Wilczek page 12: Zeroth Law: the consiervation of mass = no mass no matter.

page 16: E = mc2

page 19: Dirac: ' "I play with equations" ' ie numerical equivalences.

page 20: 'Energy more central that mass', action more central than energy.

Wilczek page 47 (cont): Screening.

page 48: Diagram of sceening

page 50: Antiscreening = asyptotic freedom. This book is as stupid as Rovelli!

Antiscreening seems very ad hoc? The ideas built around the renormalizastion of Yang-Mills theory by Veltman and 'tHooft. Yang-Mills theory - Wikipedia, Martinus J G Veltman: Nobel Lecture 1999: From weak interactions to gravitation, Gerardus 't Hooft (1999): Nobel Lecture 1999: A Confrontation with Infinity

page 73: "The Grid": 'What we perceive as empty space is really a powerful medium whose activity moulds the world ' and yet we do not feel it and it is complete arbitrary fiction as the cosmological constant problem illustrates. Wilczek builds all this on his misunderstanding of what it going o in the hadron world. I just have to put my finger on it in a 2000 word summary of his book, say the last 3 but one sections of cc24_chromodynamics [hence all these notes].

Feynman + cosmological constant.

page 85: ' Theories consistent with special relativity must be field theories' [? individual particles exist in Minkowski space].

page 86: c is a feature of the Minkowski metric, ie the sructure of space. (page 12: The quantum creation of Minkowski space). The argument for field is a bit dodgy. A light beam is in fact a swarm of particles each having an individual arrival time and an individual effect upon its annihilation. Averaging them into a field using the law of large numbers may be unphysial.

[page 365]

Computing the 'summed influence' requires accounting for each particle.

page 89: 'interaction with a virtual electon-positron pair. Slippery customers these virtual particles, cooked up by treating units of measurement as dynamic rather than kinetmatic logical principles.

'complicated, small but very specific modifications of the force that you would calculate from Maxwell's equations'.

page 90: grid of layered ethers through which we can move in inertial motion giving the eternal orbit of the Moon (modified by the [dissipative] flexibility of the Earth and Moon, not rigid bodies). 'Material ether = condensate. The time is coming for me to get into arguentative / assertive mode. To Rovelli: 'In other words you ignore my ideas at your peril because you and your fellow quantum gravtiationista are WRONG (I think).

page 93: Heavy Ion Collider Relativistic Heavy Ion Collider - Wikipedia

[page 356]

Wilczek page 94: Weak inreractions: W + Z bosons. 'striking similarities' symmetry with respect to complexity.

page 95: W + Z gain mass by superconductivity - photons slowed and made massive in a superconductor (?)

page 96: W + Z superconductor — empty space (?) Higgs condensate (?)

page 97: Empty space is multilayered multicoloured superconductor [of W + Z ?] ? Metric field - "Mother of all Grids".

pages 99-101: Wilczek is a 'field man' and so profoundly mistaken, though we can imagine a network as a sort of field with non-local connections. 'Consistency requires the metric field to be a quantum field [?]' (see above Wilczek page 85).

Friday 31 March 2023

Wilczek and Rovelli (not to mention the likes of Deutsch and all the other ones who seem to be able to ignore the cosmological constant problem) show me how far off from reality the higher echelons of theoretical physics are. Ignoring Feynman's idea that physics must begin with a realistic picture. Mathematical precision and equations count for very little when the methodology allows indefinite fudge factors (Add to these Streater and Wightman). As ever, press on. Streater & Wightman (2000): PCT, Spin, Statistics and All That

Wilczek 102: 'What Eistein meant is that it is hard to imagine how the physical world would function without the metric field. Light would not know which way to move or how fast.'

[page 351]

This question is taken care of by the constitutive role of light in the Minkowski metric on page 12: The quantum creation of Minkowski space.

Wilczek page 103: 'We have to let our concepts and equations take us where they will' but there is nothing to say that they are not totally on the wrong track. So he quotes Hertz (writing before Wigner) 'one cannot escape the feelibg that there mathematical formulae have an independent existence and an intlligence of their own'. In fact they have an embedded existence, a product of evolution and selection by survival which has brought a logically constrained (confined) universe to its present state. They tell us nothing more about the world than the statistics of a census tell us about a human culture.

page 104: 'The existence of the past depends on the existence of minds.' Silly, the past is everywhere in the present made possible by null geodesics [and other stable systems].

page 105: '. . . the most recent astronomical discovery that the Grid weighs — that the entity we perceive as space has a universal, non-zero density — crowns the case for physical reality. The concept of grid density is essentialy the same as Einstein's cosmological term, which is essentially the same as dark energy.'

page 106: 'Beause mass density and pressure have the same value everywhere, they can be regarded as intrinsic properties of space itself. That's the Grid viewpoint.'

page 107: 'Well tempered equation:' ρ = p / c2

[page 358]

Wilczek: 'well tempered equation' consistent with boost symmmetry of special relativity, ' claiming 'density of well-tempered Grid stays constsant' (do we believe this, based on the notion that a well tempered Grid gives us negative pressure p = − ρc2).

page 109: 'pressure affects the rate at which the universe is expanding.' Here [he documents that] the cosmological constant discrepancies between theory and measurement cover the range of 1044 → 10112 → ∞.

page 110: 'Maybe there is some important gap in our understanding of how gravity responds to Grid density.' Maybe the whole story of Grids and vacuums is wrong, mistaking virtual mathematical ideals for reality. He shows no connection with quantum theory, superposition and evolution. Whose fantasies are wilder? I will go with mine which has a deep root in history.

page 112: Computing matter: 'We try to find mathematical structures that mirror reality . . . By achieving such a correspondence, we can put reaality in a form we can manipulate with our minds.' Any faithful representation will do, not necessarily mathematical.

page 113: 'The algorithms of QCD empower us to program computers to churn out protons . . . '. So achieving 'Mass without mass': u and d quarks weight about 1% of the proton.

[Computation] 107 sec at 1012 flops mimics proton for 10-24 sec, say 1043 times slower. Why? Representing complex continuous algorithms numerically rather than symbolically? Knuth page v. Semi numerival computations are at the borderline between numerical and

[page 359]

symbolic. We might guess that the hadrons work symbolically. Donald E. Knuth (1981): The Art of Computer Programming

Wilczek page 114: 'quantum reality is really big.'

page 118: Multiplication of states by permutation and combination.

page 119: Laplace demon.

page 120: All this talk of complexity in computation hides the fact that the world is relatively simple and predictable at the classical scale.

page 121: Maybe the digital nature of quantum logic, dealing only in selected eigenvslues, makes the world very precise, ie atomic spectra may be become naturally defined with absolute precision by the symbolic interpretation of states which we decompose into high dimensional matrices which take a lot of computation to extract eigenvalues.

page 122: Creutz - Lattice of point [The use of lattice in Minkowski space seems to indicate a misunderstanding about the relationship between Hilbert and Minkowski spaces]. page 123: Variation and selection. Michel Creutz (1983): Quarks Gluons and Lattices

page 124: QCD determined by a small set of parameters: mass for each quark and one coupling strenth. Here we can apply Chaitin's version of Gödel's theorem, ie [cybernetic] requisite variety [to indicate that the enormous amount of computation needed to understand a hadron is grossly superfluous since a small input to a computation cannot generate a larger output]. Gregory J. Chaitin (1982): Gödel's Theorem and Information

pages 125, 127: 'the greastest scientific achievement of all time!' [maybe the greatest feat of measurment accompanied by the worst line of explanation].

page 128: The Origin of Mass. He says mass arises from the motion arising from quantum uncertainty [this seems to be the fundamental error in field theory].

page 136: 'Because if [a theory] is approximately right and can't be changed, it must be exactly right.' ?

page 138: 'ambition to make precise mathematical world models and faith that one could succeed, was the decisive inxshaustble Scientific Revolution [led astray by numerical calculation, overlooking the fact that the heart of mathematics (and the universe) is logical computaation and proof].

[page 360]

Wilczek page 139: Data Compression

page 140: Compression exploits symmetry and uses algorithmic informßation theory. Algorithmic information theory - Wikipedia

page 141: Particles and [other] stable systems are 'infinte loops' in the Turing vacuum.

page 143: Feebleness of gravity

page 149: Coupling: Gravitation, no teeth, no quanta, negligible coupling. EM, teeth, quanta, powerful coupling. The difference between cogs and belts.

page 150: Photon is like a gear because for a photon the interval between electrically charged particles is zero. So, he says, the answer is to deny the feeblness of gravitation, which leads us into a lot of silly stuff. So . . .

page 151: [Like] 'Why are protons so light?'

page 153: 'It takes energy to localize quarks' [we thought it was momentum. Δx.Δp ≈ h]. So, he says, proton mass arises from 'non completely cancelled' disturbance in gluon fields and not quite completely localized positions of quarks. Ie, we are repeating the cosmological constsant problem and treating uncerainty as a dynamic principle rather than a formal geometric pixellization. 'In this account the newest and trickiest element is the way the disturbance in the gluon field grows with distasnce [antiscreening?].

page 154: Planck units: page 155: Absolute units derive , page 156, from c, G, h [does this hocus pocus actually mean anything?].

page 157 c relates space to time, h relates time to energy, G measures curvature of space.

page 158: 'proton mass is very small in Planck units.'

[page 361]

Saturday 1 April 2023

Wilczek page 159: 'seed strong force' between quarks measured in Planck units is 1/25: 'We've overcome a major obstacle blocking the path toward a unified theory of forces' by fiddling with units rather than saying anything about reality. 'Pretty story'.

page 162: Part III Is Beauty Truth?

page 163: None of this tale can be verified because energies and momenta in the 'Planck regime' are far beyond any possible experimental realization.

page 164: Standard Model 'summarizes .. . almost everything we know about the fundamental laws of physics,' Standard Model is the Core theory.

page 165: 'The Core is Nature's last word' [you wish!].

page 166: Core: QED, QCD, Weak Interaction morphs differet flavours of quarks into one another: ud changes proton into neutron.

page 167: Weakness of gravity (?). Neutrinos have mass (very small, very little interaction).

page 171: Summary of Core (see vague figure 17.1, page 164)

page 172: 'Core . . . great achievement summing up centuries of briilliant work.' Experimentally correct, but arbitrary fiction based on the vacuum that is demolished by the cosmological constant problem.

[page 363]

page 172: (cont) 'The core contains the seeds of its own transcendence.' [?]

page 173: 'master symmetry' SO(10). Rotations in 10D space (Unitarity is rotation in 0 dimensional space, covering all possible Turing machines. Fig 17.2 page 165: Charge account where all the fundamental particles can be transformed into one another.

page 174: 'both a particlse and an antiparticles are excitations of the same field.'

page 175: Invisible "N" particle that gives mass to the neutrino. 'The Charge Account maps the mathematically ideal to the physically real.' which may be where the trouble lies.

page 177: A problem: If strong, weak and EM are all aspects of a common master force they should all have the same strength. Why? Who knows.

page 179: Again: 'A great lesson from the Core is that the entity we perceive as empty space is in reality a dynamic medium full of structure and activity [eg the world].

page 180: 'To get down to basics we need to transfer impossible amounts of energy.'

page 185: Unififcation loves SUSY: Maxwell added dE/dt → magnetism.

page 186: Dirac equation → positron.

page 187: So equations may predict new particles, new software processes) - So now we have supersymmetry intoducing new dimensions: 'quantum dimensions'. New spins.

page 188: 'Supersymmetry leads us to double the number of fields, which must be heavier than their observed siblings.'

page 202: We only understand the origin of mass in hadrons [but aything with mass will have internal process].

[page 364]

Wilczek page 203: Dark matter and energy: quantum ideal without eigenvalues? Dark energy exerts negative pressure: force has no role in general relativity [but W is always talking about force?] More 'heroic' experiments to test for axions.

page 204: 'I've shown you my choicest smooth pebble, my prettiest shell and an undiscovered ocean [which I have discovered]. I hope you've enjoyed them. After all, they're our world.' The data is good, the theory is uncontrolled imagination both in physics and theology.

page 211: Appendix B: The Multilayered, Multicoloured Cosmic Superconductor. Meissner effect - magnetic field cannot penerate, since current flow is generated to oppose magnetism. He says Meissner effect causes supercoductivity, but the opposite is also true, an application of Maxwell's equation. Meissner effect - Wikipedia

page 212: Grid: Electric and magnetic forecs result from the interplay between charged sources and virtual photons, aka field fluctuations. He claims photons are heavy in a superconductor??

page 213: So W + Z are heavy photons in a superconductor (he says). What is really important about W and Z is what they do, not their mass, ie there formal identity as units of embodied software (Landauer).

page 214: Cooper pairs = bosons

page 215: 'With more symmetry you have more possibilities for transformations [and spheres have the most] . . . '

page 217: Appendix C: From "not wrong" to (maybe) right. 'Supersymetry is too good for this world'. Symmetry breaking: which side of the road?

[page 365]

Wilczek page 250: 'strategically ignore glaring prolems' like the cosmological constant problem [again]. The core of the problem with Wilczek and physics in general is the idea that quantum fluctuations drive the world. No, it is the bifurfation into dyamic asd potential energy, Minkowski space and gravitation.

What we need is a new Turing like model of asymptotic freedom which may have some similarity to the role of the velocity of light and the generation of Minkowski space. This will be my gem, and throw out all the renormalization and screening and antiscreening on the basis that all actual communications betwen sources are one to one, computable and in all cases (other than gravitation) involve a code.

My little bits of depression (and reading all the bullshit in Wilczek's book is very depressing) can be remedied by looking at the beauty of the divine world (walking along the Torrens today) and trying to explain it reassonably rather than sticking to ancient the misunderstandings which are so deeply embedded in theology and physics.

Wilczek and the physics trade all believe that the world was made like this and it is their job to work out what the maker had in mind. The problem is different if we assume that there was a simple but powerful initial singularity which has made itself into the current world. One thing implicated in this view is the heuristc of simplicity which says that the initial stages must be very simple and easily understood (Page 25 principle 2: The heuristic of simplicity).

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. A near-obligatory acquisition for circulating physics collections.' --Gilbert Taylor

For example, in the proton, of mass mp ≈ 938 MeV , the valence quarks, two up quarks with mu ≈ 2.3 MeV , and one down quark with md ≈ 4.8 MeV , only contribute about 9.4 MeV (= 1%) to the proton's mass.

Dorothea Sophia, Mattering: A recreation of the Realism of Charles S. Peirce, Yet, as Douglas Anderson (2013) wrote in an email to me: Clarity can be used in many ways--clear skies, clear vision, clarity of a wine, etc. Peirce focuses on simple logical clarity by which he seems to mean knowing the boundaries of a concept as best we can. He borrows from Descartes and Leibniz who argue that clarity and distinctness are the two modes of measuring a definition. Peirce adds the pragmatic meaning as yet another level of clarity--ultimately for him the final measure of clarity. Thus, the better we know the possible and necessary consequences of "we" the "clearer" will our understanding of the concept be. All of this means for Peirce that there is NO absolute clarity--all concepts have some element of indeterminacy (vagueness or generality). To be intelligible for Peirce means to be something that inquiry might grasp. So Kant's "thing in itself" is unintelligible but "neutrons" are intelligible. Even "God" is intelligible insofar as a belief may have recognizable consequences. But something could be very intelligible and not very clear. And of course no unintelligible "thing" could be clear to us. back

If this success seemed to be due to sorcery, it may be of interest to explain the physical insights on which it is actually based.' back

In contrast with the traditional proof based on the paradox of the liar, this new viewpoint suggests that the incompleteness phenomenon discovered by Gödel is natural and widespread rather than pathological and unusual.'

An extensive review on the subject including detailed references to contemporary work can be found elsewhere. As is well known, the work on renormalizability of gauge theories caused a complete change in the landscape of particle physics.' back

Meissner effect - Wikipedia, Meissner effect - Wikipedia, the free encyclopedia, ' The Meissner effect (or Meissner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state when it is cooled below the critical temperature. The German physicists Walther Meissner and Robert Ochsenfeld discovered this phenomenon in 1933 by measuring the magnetic field distribution outside superconducting tin and lead samples. ' back

Nymphomaniac (film) - Wikipedia, Nymphomaniac (film) - Wikipedia, the free encyclopedia, ' Joe becomes annoyed with Seligman, accusing him of overlooking the severity of her lost sexuality to focus on the allegorical before realising he cannot relate to her stories. He goes on to confirm his asexuality and virginity, but assures her his "innocence" and lack of bias makes him the best man to listen to her story. She becomes inspired to tell him another portion of her life after noticing a Rublev-styled icon of the Virgin Mary and a discussion about the differences between the Eastern Church ("the church of happiness") and the Western Church ("the church of suffering").' back

Qian Li et al, Abyssal ocean overturning slowdown and warming driven by Antarctic meltwater, ' The abyssal ocean circulation is a key component of the global meridional overturning circulation, cycling heat, carbon, oxygen and nutrients throughout the world ocean1,2. The strongest historical trend observed in the abyssal ocean is warming at high southern latitudes, yet it is unclear what processes have driven this warming, and whether this warming is linked to a slowdown in the ocean’s overturning circulation. Furthermore, attributing change to specific drivers is difficult owing to limited measurements, and because coupled climate models exhibit biases in the region. In addition, future change remains uncertain, with the latest coordinated climate model projections not accounting for dynamic ice-sheet melt. Here we use a transient forced high-resolution coupled ocean–sea-ice model to show that under a high-emissions scenario, abyssal warming is set to accelerate over the next 30 years. We find that meltwater input around Antarctica drives a contraction of Antarctic Bottom Water (AABW), opening a pathway that allows warm Circumpolar Deep Water greater access to the continental shelf. The reduction in AABW formation results in warming and ageing of the abyssal ocean, consistent with recent measurements. In contrast, projected wind and thermal forcing has little impact on the properties, age and volume of AABW. These results highlight the critical importance of Antarctic meltwater in setting the abyssal ocean overturning, with implications for global ocean biogeochemistry and climate that could last for centuries.' back

Relativistic Heavy Ion Collider - Wikipedia, Relativistic Heavy Ion Collider - Wikipedia, the free encyclopedia, ' The Relativistic Heavy Ion Collider (RHIC) is the first and one of only two operating heavy-ion colliders, and the only spin-polarized proton collider ever built. Located at Brookhaven National Laboratory (BNL) in Upton, New York, and used by an international team of researchers, it is the only operating particle collider in the US. By using RHIC to collide ions traveling at relativistic speeds, physicists study the primordial form of matter that existed in the universe shortly after the Big Bang. By colliding spin-polarized protons, the spin structure of the proton is explored.' back

Rich Lowry, Opinion | Trump’s Huge Jan. 6 Mistake , ' The philosopher Eric Hoffer famously wrote, “Every great cause begins as a movement, becomes a business, and eventually degenerates into a racket.” What he evidently didn’t count on was great outrages becoming causes. From the perspective of the immediate aftermath of Jan. 6 it was hard enough to believe that Donald Trump would survive the event, let alone make it a plank in a powerful comeback bid just a few years later. But there was Trump in Waco, Texas, opening his inaugural rally of the 2024 campaign with a recording of the song “Justice for All” that he performed with the J6 Prison Choir, with some scenes of Jan. 6 playing on the jumbotrons. Among those favorably inclined toward it, the bloody riot at the Capitol has progressed from something to be minimized — and blamed on others, whether antifa or federal informants — to closer to something to be celebrated, almost, if not quite, Stop the Steal’s Bastille Day.' back

Rolf Landauer (1999), Information is a Physical Entity, 'Abstract: This paper, associated with a broader conference talk on the fundamental physical limits of information handling, emphasizes the aspects still least appreciated. Information is not an abstract entity but exists only through a physical representation, thus tying it to all the restrictions and possibilities of our real physical universe. The mathematician's vision of an unlimited sequence of totally reliable operations is unlikely to be implementable in this real universe. Speculative remarks about the possible impact of that on the ultimate nature of the laws of physics are included.' back

Wu Experiment - Wikipedia, Wu Experiment - Wikipedia, the free encyclopedia, ' The experiment established that conservation of parity was violated (P-violation) by the weak interaction, providing a way to operationally define left and right without reference to the human body. This result was not expected by the physics community, which had previously regarded parity as a conserved quantity. . . . As stated by We et al: If an asymmetry in the distribution between θ and 180° − θ (where θ is the angle between the orientation of the parent nuclei and the momentum of the electrons) is observed, it provides unequivocal proof that parity is not conserved in beta decay.' back

Yang-Mills theory - Wikipedia, Yang-Mills theory - Wikipedia, the free encyclopedia, 'Yang–Mills theory is a gauge theory based on the SU(N) group, or more generally any compact, reductive Lie algebra. Yang–Mills theory seeks to describe the behavior of elementary particles using these non-Abelian Lie groups and is at the core of the unification of the electromagnetic force and weak forces (i.e. U(1) × SU(2)) as well as quantum chromodynamics, the theory of the strong force (based on SU(3)). Thus it forms the basis of our understanding of the Standard Model of particle physics.' back
