Why do some people have an outsize effect on the human system? Another scale invariant property related to bosonic behaviour and the nucleation of raindrops by dust particles, related to bosonic symmetry and "an idea whose time has come", Hitler, Mao, Stalin, Jesus, Ghandi, The Beatles . . .
I am feeling funny in the head. What does this mean? Vague feeling of unbalance, compromised motor control. Walking crooked.
[page 247]
What should I do next? Continue gestating texts.
Luther introduced a biblical democracy by providing his constituents with a common text, the Bible, to act as foundation for their theological and institutional votes. A microcosm of large scale democracy which revolves on common culture and education as a foundation for a broad consensus on social decision making, something which fails when the moral foundations of society become fragmented. The foundation of democracy is moral science.
From heat engines to quantum engines. Love and entanglement. Does quantum entanglement influence statistical physics, ie statistical mechanics? Yes compare Bose, Fermi and Classical statistics. In other words, what are the theological implications of these statistical schemes when the particles involved are people (or any other elements of a symmetry)? Clare Yu: Maxwell-Boltzmann, Fermi and Bose Statistics
Have at last seen a way to explain quantum mechanics and transfinite set theory to the philosophy department. We think of the network in terms of sets and do not need to look inside the sets. This gives us the basic symmetry. The name of a set is its cardinal which names a symmetry whose elements are all the permutations (ordinal numbers) corresponding to that cardinal. We divide these sets into three classes without inquiring exactly how they work, indifferent, which merely bounce of one another, following Maxwell Boltzmann statistics, attractive that follow Bose Einstein and repulsive that are Fermi Dirac, something like this, so that we do not have to go into detail.

Analytic rigour versus synthetic love. The wonderful thing is that the supreme analysis of Whitehead and Russel led to
[page 248]
work of Gödel and Turing which opened analysis up to the softness of uncertainty opening the path to uncertainty evolution, love and creation. Here is our fundamental mathematical theological breakthrough which I have been talking to myself about for many years. I have my diaries back to 1982 and one of these days I will transcribe them and search them for the first seeds of each idea that has gone into building my theology.
Sovereignty couples to complexity, and moral science is the most complex of all.
The biblical account of creation omits many details. God said let there be light and there was light, but how did he do it? My purpose in this thesis is to speculate about how this was done. I have two starting points, the model of Gd created by Thomas Aquinas and the modern cosmological and evolutionary theory of how things came to be the way they are. So we begin with a God of absolute simplicity and an initial singularity. The next step was taken by the Christian theologian who invented the doctrine of the Trinity - one God [with three persons which we understand here to be three communication sources].
My dream is to write theology as beautiful as music.
So from Trinity to network, layered, how do we get there?
First, what has standard cosmology got to say about
[page 249]
the transition from initial singularity to universe? It is a time reversed black hole. It is easy enough to imagine the formation of a black hole given the structure of the universe we have, but how do we go in the opposite direction?
Theology and philosophy began before anybody really knew how things worked. This knowledge has only been available in the last century or so, since the advent of modern science ranging from relativity and quantum mechanics through biology and ecology to our current understanding of psychology, economics and politics. Nevertheless we my see theology as the first, rather magical, theory of everything, a search fo certainty in an uncertain world.

The essence if thesis writing is to "weaponize" an idea.
The magical history of theology
The ancient Christian theology is an hypothesis, subject to verification. If I can produce a better hypothesis, I am at least doing better.

page 13: ' Newton . . . saw his task in science as revealing God's method of governing the physical world.'
We can talk about people talking to one another without knowing their languages or all the internal details of encoding and decoding language
[page 250]
and we can do the same with all communicating entities using the symmetry of reversibility based on entropy. Philosophers have spent millennia talking about language without having the slightest clue how the human (or any other) mind works and so they are to a large extent dancing in the dark. My thesis can get a long way on entropy, reversibility and the Carnot view if communication first presented in An essay on the divinity of money. natural theology: An essay on the divinity of money
Wilczek page 33: ' . . . quarks and gluons . . . are embodied ideas.' As are all ideas of course.
Hertz on Maxwell's equations:
One cannot escape the feeling that these mathematical formulae have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers, that we get more out if them than was originally put into them. [because an algorithm expresses a symmetry which may have a very large number of instantiations.]

There can be no space nor any part of space without gravitational potentials; for these confer upon space its metrical qualities, without which it cannot be imagined at all. The

It is easy to get upset about all the examples of inadequate and deliberately incompetent management that we see around the world, most if which we can interpret as people not taking due care and responsibility t understand and deal with the consequences of their actions. (Cook) We can understand this in the context of cybernetics and control and the failure f narrow bandwidth management to address broad bandwidth problems so that the outcomes are unconstrained, random and chaotic. At the root of this we can see an application of Carnot's idea of reversibility extended from dimple thermodynamics to statistical mechanics and information theory. Here we need to see privacy as entropy control, me keeping to myself so as not to be disrupted by outside forces such as the secret police. Tim Cook: 2019 Commencement address by Apple CEO
Scepticism-essay, emphasising simplicity as an heuristic method. We learn from Wilczek that the structure of the atomic nucleus, and of protons and neutrons, is already exceedingly complex but logically and mathematically complete and consistent, so it may have an evolutionary origin, but like the origin of life, it is a big leap
[page 253]
from initial singularity to stable complexity and we seek an explanation. The candidate proposed in this essay is network structure which has on one hand enormous power to explore possibilities and on the other a straightforward ability to eliminate inconsistencies because they simply cannot happen and this selective process happens at all places and times serving to keep the universal system on the straight and narrow. The time constant of this guidance varies from infinitesimal fractions of a second to the life of the universe. These ideas make me happy in the face of the sea of irrational political troubles that I read about every day. War, obviously enough, in one of the correction mechanisms serving to destroy inconsistency, but we would prefer to achieve the same ends by the softer and less destructive means of diplomacy. We look forward to the time when national security spending is shared equally between the military and the diplomats.
Back to Wilczek page 85 Why field theories?
LOOKING = TRANSFORMATION
Wilczek page 87: 'Field theory integrates influences of individual particles by realistically modulated superposition.
page 88: Field are convenient, but are they a 'necessary ingredient of ultimate reality [meaning here proximate reality].'
page 102: 'Experimenters have worked very hard to discover any effect that could be ascribed to quantum fluctuations in the metric field, or in other words, quantum gravity.'
[page 254]
Wilczek page 102: 'String field theory is clumsy at best'.
Einstein geometrodynamics describe the metric field.
'Is the metric field s condensate?' [Condensate: page 90: 'Physicists usually call these materials ethers condensates. One could say that they . . . condense spontaneously out of empty space . . .. The best understood of these condensates consists quark-antiquark pairs . . . σ mesons . . . have negative total energy . . . the energy cost of making these particles is more than made up by the energy you can liberate by unleashing the attractive forces between them as thy bind into little molecules.' ???]
Augustine: What was God doing before he created the world? (Confessions chapter 10) - Presentism / local presentism / continuous creation.
'Until God creates the world no "past" exists. So the question does not make sense.' God is eternal, so time and space are emergent.
page 104: 'The flow of time commences with the condensation of the metric field'.
Einstein 'cosmological term'.
page 107: 'well tempered equation ρ (density) = -p (pressure) / c2 from special relativity.
page 108: Expansion of space with density ρ gives negative pressure since ρ = -p/c2 so enough energy is gained to make enough mass to keep ρ constant [continuous creation?]
page 109: Cosmological constant problem: QQbar 1044 out; weak 1056 out; unified 10112 out; (see Weinberg)
page 110: Why so wrong? Because zero point energy wrong, because interpretation of quantum fluctuation ie uncertainty is wrong. Uncertainty is formal, not dynamic [?].
[page 255]
Always stretching to reach a little bit further. Wilczek's story is nice, but we need to replace the grid with a network and avoid a few hundred orders of magnitude discrepance between theory and observation [the answer, I think, lies in the fact is that the grid is solid massive and continuous whereas the network is a web of discrete sources and channels. Shannon's theorem is effective in the net whereas the grid is a continuous blur].
Wilczek page 121: Chaos theory assumes the absence of control.
Back to page 105: 'The concept of grid density is essentially the same as Einstein's cosmological term, which is essentially the same as "dark energy".
Friday 21 June 2019
page 155: 'Numbers themselves can't provide physical units for measurement: they can't make rulers or scales or clocks.' But they do provide a universal measure count = entropy.
page 157: 'Fundamental constants are conversion factors' c converts T to L, h converts T -1to E-1 and F converts energy to curvature. Each of these constants has 'embedded dimensions', c (eg) = LT-1 etc.

Sailing in difficult but stimulating waters. Since the turn of century one might guess that about 100 000 physicists and 100 billion dollars. have gone into the development of the Standard Model that political physicists have claimed to be the greatest human achievement in history (Wilczek page 164).Hard to believe when it seems so obviously wrong, producing the biggest discrepancy between theory and measurement ever recorded, a factor in the range of 10100. Yet how can I put my little bit of theological research against this, and, more particularly, how can I make it into a credible honours thesis. The key, it seems, may be philosophical vagueness, attacking an easy target like Christianity rather than physics, more difficult because it does closely track reality in its less speculative regions.

'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, P van Baal, F A Bais, C Becchi, M Creutz, A DeRujula, B S DeWitt, F Englert, L D Faddeev, P Hasenfratz, R Jackiw, P van Nieuwenhuizen, A Polyakov, R Stora, S Weinberg, F Wilczek, E Witten, C N Yang.

Weinberg, Steven, The Quantum Theory of Fields Volume I: Foundations, Cambridge University Press 1995 Jacket: 'After a brief historical outline, the book begins anew with the principles about which we are most certain, relativity and quantum mechanics, and then the properties of particles that follow from these principles. Quantum field theory then emerges from this as a natural consequence. The classic calculations of quantum electrodynamics are presented in a thoroughly modern way, showing the use of path integrals and dimensional regularization. The account of renormalization theory reflects the changes in our view of quantum field theory since the advent of effective field theories. The book's scope extends beyond quantum elelctrodynamics to elementary partricle physics and nuclear physics. It contains much original material, and is peppered with examples and insights drawn from the author's experience as a leader of elementary particle research. Problems are included at the end of each chapter. '

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

Albert Einstein, Ether and Relativity, ' The development of the theory of electricity along the path opened up by Maxwell and Lorentz gave the development of our ideas concerning the ether quite a peculiar and unexpected turn. For Maxwell himself the ether indeed still had properties which were purely mechanical, although of a much more complicated kind than the mechanical properties of tangible solid bodies. But neither Maxwell nor his followers succeeded in elaborating a mechanical model for the ether which might furnish a satisfactory mechanical interpretation of Maxwell's laws of the electro-magnetic field. The laws were clear and simple, the mechanical interpretations clumsy and contradictory. Almost imperceptibly the theoretical physicists adapted themselves to a situation which, from the standpoint of their mechanical programme, was very depressing. They were particularly influenced by the electro-dynamical investigations of Heinrich Hertz. For whereas they previously had required of a conclusive theory that it should content itself with the fundamental concepts which belong exclusively to mechanics (e.g. densities, velocities, deformations, stresses) they gradually accustomed themselves to admitting electric and magnetic force as fundamental concepts side by side with those of mechanics, without requiring a mechanical interpretation for them. Thus the purely mechanical view of nature was gradually abandoned.' back |
Alexandra Stevenson and Keith Bradsher, As Hong Kong Erupted Over Extradition Bill, City's Tycoons Waited and Worried, ' HONG KONG — Weeks before this semiautonomous city erupted in political chaos over a contentious extradition bill, more than 200 of its most powerful business leaders were summoned to the Chinese government’s headquarters here.
The message from Beijing: If you have worries about the bill, keep them to yourself.
And they did — until hundreds of thousands of protesters took to the streets. When the Chinese government appeared unsure how to react, and a later protest turned violent, business leaders were stirred into action. Deals were canceled. Money appeared to flee, raising concerns that Hong Kong could cede financial ground to Singapore. Within days, a handful of business leaders were publicly suggesting that the Hong Kong government should back down. ' back |

Born rule - Wikipedia, Born rule - Wikipedia, the free encyclopedia, 'The Born rule (also called the Born law, Born's rule, or Born's law) is a law of quantum mechanics which gives the probability that a measurement on a quantum system will yield a given result. It is named after its originator, the physicist Max Born. The Born rule is one of the key principles of the Copenhagen interpretation of quantum mechanics. There have been many attempts to derive the Born rule from the other assumptions of quantum mechanics, with inconclusive results. . . . The Born rule states that if an observable corresponding to a Hermitian operator A with discrete spectrum is measured in a system with normalized wave function (see bra-ket notation), then
the measured result will be one of the eigenvalues λ of A, and
the probability of measuring a given eigenvalue λi will equal <ψ|Pi|ψ> where Pi is the projection onto the eigenspace of A corresponding to λi'. back |

Still, with the appropriate interpretation, it does describe the quantum amplitude for finding a point particle in various places, the relativistic wavefunction, but the particle propagates both forwards and backwards in time.

One important consequence of the equations is that they demonstrate how fluctuating electric and magnetic fields propagate at the speed of light.' back |

Pope Paul VI, Inter Insigniores: On the question of admission of women to the ministerial priesthood, '. . . in execution of a mandate received from the Holy Father and echoing the declaration which he himself made in his letter of 30 November 1975, the Sacred Congregation for the Doctrine of the Faith judges it necessary to recall that the Church, in fidelity to the example of the Lord, does not consider herself authorized to admit women to priestly ordination.' back |
R. Jefrey Smith, Hypesonic Missiles Are Unstoppable. And They're Starting a New Global Arms Race, ' On March 6, 2018, the grand ballroom at the Sphinx Club in Washington was packed with aerospace-industry executives waiting to hear from Michael D. Griffin. . . . Griffin is now the chief evangelist in Washington for hypersonics, and so far he has run into few political or financial roadblocks. Lawmakers have supported a significant expansion of federal spending to accelerate the delivery of what they call a “game-changing technology,” a buzz phrase often repeated in discussions on hypersonics.' back |
Reuters, Scientists shocked by Arctic permafrost thawing 70 years sooner than predicted, 'Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.
A team from the University of Alaska Fairbanks said they were astounded by how quickly a succession of unusually hot summers had destabilised the upper layers of giant subterranean ice blocks that had been frozen solid for millennia.
“What we saw was amazing,” Vladimir Romanovsky, a professor of geophysics at the university, told Reuters. “It’s an indication that the climate is now warmer than at any time in the last 5,000 or more years.“ ' back |
Sarah Boseley , One in three women suffers violence, study finds, 'More than a third of all women worldwide – 35.6% – will experience physical or sexual violence in their lifetime, usually from a male partner, according to the first comprehensive study of its kind from the World Health Organisation (WHO).' back |

Steven Weinberg, The Cosmological Constant Problems, 'Abstract. The old cosmological constant problem is to understand why the vacuum energy is so small; the new problem is to understand why it is comparable to the present mass density. Several approaches to these problems are reviewed. Quintessence does not help with either; anthropic considerations offer a possibility of solving both. In theories with a scalar field that takes random initial values, the anthropic principle may apply to the cosmological constant, but probably to nothing else.' back |
The Editors, Commonweal, Stumbling toward War, ' While the administration continues to call for greater international pressure on Iran, many European leaders are urging restraint on the part of both countries. Having learned the lessons of the war in Iraq, they do not want to be drawn into another conflict built on lies and exaggeration. The United States should understand that, this time around, there will be no “coalition of the willing.” Iran retains the support of China and Russia, two countries that, unlike Iran, do have the ability to inflict grave harm on the United States.' back |
Tim Cook, 2019 Commencement address by Apple CEO, ' First things first, here’s a plain fact.
' Silicon Valley is responsible for some of the most revolutionary inventions in modern history. . . .
But lately, it seems, this industry is becoming better known for a less noble innovation: the belief that you can claim credit without accepting responsibility.
We see it every day now, with every data breach, every privacy violation, every blind eye turned to hate speech. Fake news poisoning our national conversation. The false promise of miracles in exchange for a single drop of your blood. Too many seem to think that good intentions excuse away harmful outcomes.' back |
Wojciech Hubert Zurek, Quantum origin of quantum jumps: breaking of unitary symmetry induced by information transfer and the transition from quantum to classical, 'Submitted on 17 Mar 2007 (v1), last revised 18 Mar 2008 (this version, v3))
"Measurements transfer information about a system to the apparatus, and then further on -- to observers and (often inadvertently) to the environment. I show that even imperfect copying essential in such situations restricts possible unperturbed outcomes to an orthogonal subset of all possible states of the system, thus breaking the unitary symmetry of its Hilbert space implied by the quantum superposition principle. Preferred outcome states emerge as a result. They provide framework for the ``wavepacket collapse'', designating terminal points of quantum jumps, and defining the measured observable by specifying its eigenstates. In quantum Darwinism, they are the progenitors of multiple copies spread throughout the environment -- the fittest quantum states that not only survive decoherence, but subvert it into carrying information about them -- into becoming a witness.' back |
