I am going through a thin period in the theology business trying to put some more solid realism under my rather gung-ho claim that the universe is divine and finding it difficult, but, I hope productive [becasue I have been working to a very low standard because my "opposition" the Christian belief system is so in-credible]. I need to get a better grip on my objections to quantum field theory to try to gain a deeper understanding to map onto my theological aspirations. The review of scientific-theology is leading me that way and I hope it will be fruitful in building a logical and empirical extension of my feeling that might capture the interest of some professionals and go somewhat viral. The technique of overreaching to drag myself forward is excellent for driving research and discovery but I must fall back to firmer ground for publication, although I give myself licence to let it all hang out in these notes. Part of my probem is a search for heaven on Earth ["a new world order"] which might be rather naive given the reality of evolution, but there is no reason to exclude a
[page 294]
formally realistic algorithm which may be difficult to out into practice given human nature, but then multicellular organims have been difficult to realize given the variety of unicellular natures and viruses in the world. Edward Fishman: The World Order Is Dead. Here's How to Build a New One for a Post-Coronavirus Era
The link that makes it all work is that computation and quantum mechanics are both cyclic and the passage from complex amplitude to reality requires one quantum of action, that is one cycle of action. So once again I am rescued from desperation by an old insight and refreshed press on [creation saves me again, the joy of seeing a way out of an impossible predicament].

Teilhard de Chardin writes about he Phenomenon of Man but on the whole we are more interested in The Phenomenon of Me. Although my genes are with me for life with a bit of epigenetic modification, what I call me is a product of the socio-linguistic-theological milieu in which I grew up which was a version of the twisted milieu of divine murder and eternal life that Teilhard de Chardin defends on the Divine Milieu. One wonders whether he really believed it all or just toed the line to keep his rather cushy job in the Church. Pierre Teilhard de Chardin: The Phenomenon of Man, Teilhard de Chardin (2001): The Divine Milieu
The tacit dimension of the Schrödinger equation is a
[page 295]
countably infinite dimensional Hilbert space. If we think of each dimension of the Hilbert space as a placeholder for a decimal digit, the Hilbert space is capable of representing [infinite decimals] of all the real numbers and, since the cardinals of the real and complex numbers are equivalent, all the complex numbers. We may also consider each dimension of the Hilbert space as a placeholder for one of the countably infinite set of turing machines, so the Hilbert space may also be seen as the domain of the transfinite network.
Teilhard de Chardin's story fits perfectly with the divine universe once we delete all the Jesus personality cult stuff and the sin and redemption and just accept that the universe is divine best understood by cognitive cosmology.

Matrix mechanics: 'The matrix formulation was built on the premise that all physical observables are represented by matrices, whose elements are indexed by two different energy levels. The set of eigenvalues of the matrix were eventually understood to be the set of all possible values that the observable can have. Since Heisenberg's matrices are Hermitian, the eigenvalues are real.
'If an observable is measured and the result is a certain eigenvalue, the corresponding eigenvector is the state of the system immediately after the measurement. The act of measurement in matrix mechanics 'collapses' the state of the system. If one measures two observables simultaneously, the state of the system collapses to a common eigenvector of the two observables. Since most matrices don't have any eigenvectors in common, most observables can never be measured precisely at the same time. This is the uncertainty principle.
If two matrices share their eigenvectors, they can be simultaneously diagonalized. In the basis where they are both diagonal, it is clear that their product does not depend on their order because multiplication of diagonal matrices is just multiplication of numbers. The uncertainty principle, by contrast, is an expression of the fact that often two matrices A and B do not always commute, i.e., that AB − BA does not necessarily equal 0. The fundamental commutation relation of matrix mechanics,
Σk (XnkPkm) = ih/2π δnm
implies then that there are no states that simultaneously have a definite position and momentum.
this principle of uncertainty holds for many other pairs of observables as well. For example, the energy does not commute with the position either, so it is impossible to precisely determine the position and energy of an electron in an atom. Matrix mechanics - Wikipedia
Given that the matrix formulation (and the wave formulation) are correct. So what does this mean?
We may think of a differential operator as the output of a market, so exchange rate = d(US)/d(AU) is determined by a dimension of the money markets that in fact relate the curved spaces of national economies to one another, at least as perceived by participants in the money market. We might think of an action market that determines the value of a
[page 297]
quantum of action in various contexts, perhaps indicating that a high level action is more valuable (has a greater effect) than a low level action.
Matrix mechanics and the uncertainty principle tell us that the translation between different codes is of limited precision [not if the codes are digital and every digit can be translated precisely into a corresponding digit?]. Zurek shows that error free communication requires sharing a code which enables [is equivalent to] simultaneous diagonalization [in effect digitization via eigenfunctions] of observer and observed.
We are looking for a way of identifying quantum mechanics with a logical network and the route seems to be a combination of matrix mechanics, wave mechanics, path integrals and Feynman diagrams and special relativity. Maybe another look at Jauch and quantum logic [or see Nielsen and Chuang, who seem to think matrix mechanics is enough for quantum computation and communication].

All this physical stuff is not very human but possibly worth it in the long run bolstering the prolegomena but perhaps it is time to get a bit passionate, political and human and exploit the foundation of the story that the universe is divine and we are aiming for the creation of heaven on earth driven by the lust for life and the salvific value of creation and the rules of reality, the new world order. The internet has revealed a enormous burden of psychological diseases on the planet, some organic but mostly social. By this criterion we would have to count Trump and his murderous followers as sick people. What we need to do really is simply to imitate the structure of multicellular organisms which are built around a genetic community and an immune system. Jeffrey Nicholls: Prolegomenon to Scientific Theology
But do I feel this? Am I excited by the prospect of preaching a new world like Teilhard de Chardin did? Not much because
[page 298]
it seems a pretty hopeless task, but perhaps no more hopeless than identifying god with the world.

The second law of thermodynamics is the driving force behind the lust for life because we love high entropy wide open spaces. Looking back 33 years to the theory of peace I see that my idea that Cantors theorem is the key to space, social distance and peace was spot on, very encouraging when I sometimes feel I am on a hopeless quest [the problem is to find an algorithm for measuring entropy which gives higher values to complex organisms like myself than the equivalent amount of gas].

Ideas in the mind, like things in the world, move themselves led by the potentials in which they find themselves. Our minds are tuned to the most attractive thing in the world, potential, which is why we are so easily led astray by scammers like the church.
Wilczek: Nobel Prize address. Frank Wilczek: Nobel Lecture: Asymptotic Freedom: from Paradox to Paradigm, Wilczek: The Lightness of Being: Mass, Ether, and the Unification of Forces
Wilczek in 't Hooft page 295: '(In the present formulation of physics quantum theory itself appears as a set of independent principles which loosely define a conceptual framework. It is not absurd to hope that in the future these principles will be formulated more strictly, in a way that involves symmetry deeply.)'
[page 299]
Our minds are attuned to the most attractive things on Earth, which are possibilities, which is why we are such easy marks for fairy tales like the Catholic history of salvation.
The simplest and most appropriate approach to quantum mechanics for my purposes here is quantum computation, because it has to do with small Hilbert spaces, explores the subtleties of quantum theory and is close to the network approach in which I am interested. Further, it predates the existence of space, existing in a realm of pure time-energy, creating space as it goes and it seems to me in this way avoiding all the difficulties of quantum field theory, logically creating spacetime and the particles within it.

Looking at myself I see not an activist but a pacifist, not a person trying to make a difference by being connective and talkative but by trying to understand how thing work and explain it to myself in sufficient detail to make myself comfortable with a point of view and then write about it. My long term strategy is to document this work on this website so as to be my background if and when I get some sort of political hearing. In the meantime I go up and down in my feeling toward what I am trying to do, frustrated perhaps by my inability to make clear sense of the foundations of the universe and to document the path from the classical god of Aquinas to the cognitive cosmology that I see as framing the whole divine universe, but every day I make fresh attacks on this problem and try to document my tiny tentative steps and dreams here.
[page 300]
My new trinity of websites, creation saves, divinityrules and lust4life are an attempt to capture the potential that defines the creative motion of the universe, the potential which I feel in retrospect is captured in my application of Cantor's transfinite symbolism to a theory of peace based on creating a social space large enough for us all to be free but coherent enough to provide the divine milieu that creates the space in which we freely move.

The big effort is to write something which will put an end to war by removing the causes of war. Basically a cybernetic question, forever unanswerable because the future is generally more complex than the past.

From Library Journal
"The published editions of Women in Love , probably Lawrence's greatest novel, have always been remarkably corrupt due to a lengthy, complex process of revision and transcription, a threatened libel suit, and numerous unauthorized bowdlerizations. The editors of this new Cambridge Edition have labored scrupulously to produce an authoritative text. What emerges, if not dramatically different, is fresher and more immediate. The introduction provides a valuable history of the novel's composition, revision, publication, and reception, and though the elaborate textual apparatus is strictly for advanced students of bibliography, the notes are splendid. Lawrence's 1919 Foreword and two early discarded chapters are also included. The recovery of a modern classic.' Keith Cushman, Univ. of North Carolina, Greensboro

Nielsen, Michael A, and Isaac L Chuang, Quantum Computation and Quantum Information, Cambridge University Press 2000 Review: A rigorous, comprehensive text on quantum information is timely. The study of quantum information and computation represents a particularly direct route to understanding quantum mechanics. Unlike the traditional route to quantum mechanics via Schroedinger's equation and the hydrogen atom, the study of quantum information requires no calculus, merely a knowledge of complex numbers and matrix multiplication. In addition, quantum information processing gives direct access to the traditionally advanced topics of measurement of quantum systems and decoherence.'

This theory gives precise mathematical responses to questions like: What is a quantized field? What are the physically indispensable attributes of a quantized field? Furthermore, Axiomatic Field Theory shows that a number of physically important predictions of quantum field theory are mathematical consequences of the axioms. Here Raymond Streater and Arthur Wightman treat only results that can be rigorously proved, and these are presented in an elegant style that makes them available to a broad range of physics and theoretical mathematics.'

't Hooft, Gerardus, 50 Years of Yang Mills Theory, World Scientific 2005 ' On the 50th anniversary of Yang-Mills theory, this invaluable volume looks back at the developments and achievements in elementary particle physics that ensued from that beautiful idea.During the last five decades, Yang-Mills theory, which is undeniably the most important cornerstone of theoretical physics, has expanded widely. It has been investigated from many perspectives, and many new and unexpected features have been uncovered from this theory. In recent decades, apart from high energy physics, the theory has been actively applied in other branches of physics, such as statistical physics, condensed matter physics, nonlinear systems, etc. This makes the theory an indispensable topic for all who are involved in physics.An international team of experts, each of whom has left his mark on the developments of this remarkable theory, contribute essays or more detailed technical accounts to this volume. These articles highlight the new discoveries from the respective authors' perspectives. The distinguished contributors are: S Adler, F A Bais, C Becchi, M Creutz, A De Rujula, B S DeWitt, F Englert, L D Faddeev, P Hasenfratz, R Jackiw, A Polyakov, V N Popov, R Stora, P van Baal, P van Nieuwenhuizen, S Weinberg, F Wilczek, E Witten, C N Yang. Included in each article are introductory and explanatory remarks by the editor, G 't Hooft, who is himself a major player in the development of Yang-Mills theory.

Wilczek, Frank, The Lightness of Being: Mass, Ether, and the Unification of Forces, Basic Books 2008 ' In this excursion to the outer limits of particle physics, Wilczek explores what quarks and gluons, which compose protons and neutrons, reveal about the manifestation of mass and gravity. 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

I was born at the tail end of the baby boom and benefited from a women’s liberation movement that sent the message that my sex wasn’t an obstacle to whatever I chose to do with my life. My mom never got anything close to that kind of message, but her refusal to accept the parameters of the life she was supposed to lead allowed her to help change history.

Summary: The idea that Quarks that are born free are confined and can’t be pulled apart was once considered a paradox. The emerging theory for strong interactions, Quantum Chromo Dynamics (QCD) predicts the existence of gluons, which together with quarks can be seen indirectly as jets from hard scattering reactions between particles. Quantum Chromo Dynamics predicts that the forces between quarks are feeble for small separations but are powerful far away, which explains confinement. Many experiments have confirmed this property of the strong interaction. '.

This cooling is largely associated with ~2°C change in the North Atlantic. Current global temperatures of the past decade have not yet exceeded peak interglacial values but are warmer than during ~75% of the Holocene temperature history.

Neil Bailey & Daniel West, Are the COVID19 restrictions really worth the cost? A comparison of estimated mortality in Australia from COVID19 and economic recession, ' There has been considerable public debate about whether the economic impact of the current COVID19 restrictions are worth the costs. Although the potential impact of COVID19 has been modelled extensively, very few numbers have been presented in the discussions about potential economic impacts. For a good
answer to the question “will the restrictions cause as much harm as COVID19?” credible evidence-based estimates are required, rather than simply rhetoric. Here we provide some preliminary estimates to compare the impact of the current restrictions against the direct impact of the virus. Since most countries are currently
taking an approach that reduces the number of COVID19 deaths, the estimates we provide for deaths from COVID19 are deliberately taken from the low end of the estimates of the infection fatality rate, while estimates for deaths from an economic recession are deliberately computed from double the high end of
confidence interval for severe economic recessions. This ensures that an adequate challenge to the status quo of the current restrictions is provided. Our analysis shows that strict restrictions to eradicate the virus are likely to lead to at least eight times fewer total deaths than an immediate return to work scenario.' back |

When it is most difficult to imagine the world getting better, they’ve summoned the creativity — and the courage — to invent the world anew. . . . back |
Thomas L. Friedman, Make America Immune Again, ' This pandemic has both exposed and exacerbated the fact that over the last 20 years we as a country have weakened so many sources of our strength. We’ve simultaneously eroded our cognitive, ecological, economic, social, governance, public health and personal health immune systems — all the sources of resilience we need to get through this pandemic with the least damage to lives and livelihoods.
All these immune deficiencies are the logical outcome of how we’ve let ourselves go as a country, how we’ve let ourselves be dumb-as-we-wanna-be for so many years — devaluing science and reading, bashing public servants for political sport, turning politics into entertainment, not to mention adopting horrible eating habits that have left 40 percent of Americans obese.' back |
Tristan Ahtone & Robert Lee, Ask Who Paid for America's Universities, ' An investigation we did for High Country News found that the act redistributed nearly 11 million acres, which is almost the size of Denmark. The grants came from more than 160 violence-backed land cessions made by close to 250 tribal nations. When adjusted for inflation, the windfall netted 52 universities roughly half a billion dollars.
The coronavirus pandemic has magnified the United States’ disparities and prompted conversations about its values. A cleareyed history of how land-grant universities profited from violence and expropriation can provide a starting point to confront the nation’s record of genocide.' back |
