From an information encoding point of view the transition from time to space-time is marked by the transition from time division multiplexing to space division multiplexing, from sequential thought as I write these words in my mind to the spatial extension of these words on paper, from serial transmission, the basic means of communication, to parallel transmission, which depends on the existence of memory for the transmission of a lump of data as a unit. As I walk around I am parallel, transmitting all the information in my body as a unity. Serial Communication - Wikipedia
A new era after a brief period resting in my old home for the last 40 years and contemplating the disposal of the property and the library that I built up there.
Can we write the constitution of the universe in terms so wide that it serves the whole creative process from the procession of the world from the initial singularity to the creation of nations from sets of people?
[page 193]
The natural starting point for a critique of quantum field theory as developed by Zee is his presentation of Feynman's path integral explanation of the propagator, the rate of communication between two states [my preferred explanation is that 'propagation' occurs as a single quantum of action, statistically inhibited by the need to establish harmony (tuning) between source and destination, identical, for instance, to tuning one's radio].
Constitutionality is to be built on evidence, not fantasy and gossip, all the way from physics to the development and application of law and justice.
The usual story; Q: Quid est hoc quod est esse? A: Deus esse.

Although I see many problems with quantum field theory I fear, in the cold early hours of the morning, that I have no answers.
Calculation ≡ applied logic.
Carlo Rovelli: Helgoland Carlo Rovelli (2021): Helgoland
The initial distinction of states of action in the world is by frequency which we equate with energy. The next step in differentiation is by spatial location enabling two particles of the same energy, like photons, to exist simultaneously in different positions (maybe this holds only for fermions). Here the velocity of light enters in some way to maintain contact communication despite spatial separation.

Rovelli page 44: The phenomena from which the strangeness of quantum derives is called quantum superposition. Dirac page 4 → interference. P A M Dirac (1983); The Principles of Quantum Mechanics (4th ed)
Rovelli page 68; 'The world is a dense web [network] of interactions'. Non interaction ≡ non existence. Initial singularity interacts with itself, as does the universe.
Event = meeting = particle.
How do bosons and fermions interact? By spin. Photon spin 1 can flip an electron spin ½ from - ½ to + ½, a specific example of a general process closely coupled to the quantum of action / angular momentum/
Anything I am not in contact with, ie knowing, is spacelike separated from me. So we might see unknown amplitudes as outside our personal light cones, and it is only when my amplitude contacts your amplitude that we know eachother.
page 71-72: This brings relativity into the area of knowledge by contact appropriate for cognitive cosmology.
[page 195]
The creation of space is the creation of spacelike separation which is the creation of ignorance. Ignorance ≡ spatial distance.
Isolation is as important as contact for the development of a world of many parts.

Although I would like to digitize the universe at the microscopic level I like continuity and long distance anticipation when I am driving, made possible by photon [travelling much faster than massive vehicles].
The theory of relativity gives us the foundation for declaring points outside the light cone of a specific point to be spacelike separated from that point and therefore having no causal connection with it. Nevertheless all particles in the universe within or outside their mutual light cones are parts of the same universe and therefore have some connection which we can imagine as arising from the past when the universe was small, or from the fact that the world of amplitudes and 'spooky action at a distance' is real and connects all points in the universe even though it may lack the ability, like entanglement, to be used as a medium for information transfer because the sender cannot predict or control the outcome of its observation and so is not in a position to predict the outcome of an observation by the receiver. We may say that the spooky world is real but not deterministic enough to be used for communication or control and so has features in common with spirituality and emotion, a realm of reality outside the immediate purview of rational deterministic processes subject to scientific investigation. Salart et al: Testing the speed of 'spooky action at a distance
[page 196]
We may couple this idea with the notion that from the point of view of gravitation the universe is simply one particle and so there is in a sense no possibility of observation which will yield different results to be carried by particles corresponding to eigenvalues of interacting matrices. The universe, since it is unique, is in effect an unobserved particle. Inside it, nevertheless, particles and observations can come to be by processes analogous to the procession of the persons of the trinity whose nature is strictly defined by their relationships to one another within a globally undefined system. In other words, there is no god's eye view of the universe that makes it real in the way that an interaction between photons and electrons becomes real, ie observable.

My perennial question: is there any future in my attempt to follow Aristotle's footstep from physics to theology? The big barrier at the moment, represented by the sheer complexity of the physical theories of the nature of the world, is that the story seems too difficult for me to understand or tell. At one end we have the traditional simplicity of god and the initial singularity which appear to be an excellent bridge from the past to the future. On the other is the enormous theoretical complexity of the world as we currently experience it and the difficulty of cutting a clear and simple path between the beginning and now. The traditional answer is that the omnipotent and omniscient god takes care of all this. In physics the equivalent answer is that it all comes out in the big bang [and the little bangs we make in our particle accelerators]. In my world the transfinite network provides a source of entropy, particularly since von Neumann shows that quantum observation, ie quantum communication, increases entropy. In my world the transfinite network provides a source of entropy
[page 197]
quite competent to explain the complexity of the world but the detail escape me. The methodology of evolution by variation and selection working within this paradigm serves as an adequate explanation for this trajectory, particularly since von Neumann shows that quantum observation, ie quantum communication, increases entropy. So we have a good framework and what troubles me is how to match this with the current state of the physicists' explanation of how things are. One would like to produce a radical simplification of physics based on the evolutionary mechanism that gives us the world as we experience it. Watching the news, we see variation and selection at work, both in its successes and failures and we are looking for theological guidance to increase the success rate at the expense of the failure rate, but we must face the inherent fact that the future is uncertain. Requisite variety tells us that there is no omnipotent controller, so we are limited to pursuing a policy of no regrets. This applies as much to me as to anybody else, so I am pursuing my explorations while trying to manage my losses. John von Neumann: Mathematical Foundations of Quantum Mechanics, chapter 5.
Rovelli page 73: 'All properties of all objects are relational' [but I do have constant properties that are specified by my relation to myself].
page 74: 'The "quantum state" ψ is always a relative state. *This is the central technical feature of the relational interpretation.'

'Pitting scientific terrorists against the cardinals of Vatican City, this well-plotted if over-the-top thriller is crammed with Vatican intrigue and high-tech drama. Robert Langdon, a Harvard specialist on religious symbolism, is called in by a Swiss research lab when Dr. Vetra, the scientist who discovered antimatter, is found murdered with the cryptic word "Illuminati" branded on his chest. These Iluminati were a group of Renaissance scientists, including Galileo, who met secretly in Rome to discuss new ideas in safety from papal threat; what the long-defunct association has to do with Dr. Vetra's death is far from clear. Vetra's daughter, Vittoria, makes a frightening discovery: a lethal amount of antimatter, sealed in a vacuum flask that will explode in six hours unless its batteries are recharged, is missing. Almost immediately, the Swiss Guard discover that the flask is hidden beneath Vatican City, where the conclave to elect a new pope has just begun. Vittoria and Langdon rush to recover the canister, but they aren't allowed into the Vatican until it is discovered that the four principal papal candidates are missing. The terrorists who are holding the cardinals call in regarding their pending murders, offering clues tied to ancient Illuminati meeting sites and runes. Meanwhile, it becomes clear that a sinister Vatican entity with messianic delusions is in league with the terrorists. Packing the novel with sinister figures worthy of a Medici, Brown (Digital Fortress) sets an explosive pace as Langdon and Vittoria race through a Michelin-perfect Rome to try to save the cardinals and find the antimatter before it explodes. Though its premises strain credulity, Brown's tale is laced with twists and shocks that keep the reader wired right up to the last revelation.'

Nin, Anais, Incest: From a Journal of Love: The Unexpurgated Diary of Anais Nin 1932-1934, Houghton Mifflin Harcourt 1992 Amazon editorial review: From Library Journal
"This second volume of the unexpurgated version of Nin's diary spans the period from October 1932 to November 1934. It draws upon previously unpublished material from the period covered by the first volume of the diary as published in 1966. Incest follows Henry & June ( LJ 10/1/86), focusing not only on Nin's continued relationship with author Henry Miller but also on her physical and emotional attachments to four other men. Nin offers intimate details of disturbing events such as her intense incestuous affair with her father and her abortion during her sixth month of pregnancy. Her diary offers direct insight into a narcissistic, passionate, analytical, and complex mind, but the brief introduction does disappointingly little to explain the editorial process that created this version of Nin's diary, which differs dramatically in style and content from its expurgated counterpart. Nevertheless, this is an important supplement to the 1966 diary and is recommended for most literature collections.'

Rovelli (2021), Carlo, and Erica Segre & Simon Carnell (translators), Helgoland, Allen Lane / Penguin 2021 ' In June 1925, twenty-three-year-old Werner Heisenberg, suffering from hay fever, retreated to a small, treeless island in the North Sea called Helgoland. It was there that he came up with one of the most transformative scientific concepts- quantum theory.
Almost a century later, quantum physics has given us many startling ideas - ghost waves, distant objects that seem magically connected to each other, cats that are both dead and alive. At the same time, countless experiments have led to practical applications that shape our daily lives. Today our understanding of the world around us is based on this theory. And yet it is still profoundly mysterious.
In this enchanting book, Carlo Rovelli, one of our most celebrated scientists, tells the extraordinary story of quantum physics and reveals its deep meaning- a world made of substances is replaced by a world made of relations, each particle responding to another in a never ending game of mirrors.

Papers
Salart, Daniel, et al, "Testing the speed of 'spooky action at a distance", Nature, 454, , 14 August 2008, page 861-864. 'Correlations are generally described by one of two mechanisms: either a first event influences a second one by sending information encoded in bosons or other physical carriers, or the correlated events have some common causes in their shared history. Quantum physics predicts an entirely different kind of cause for some correlations, named entanglement. This reveals itself in correlations that violate Bell inequalities (implying that they cannot be described by common causes) between space-like separated events (implying that they cannot be described by classical communication). Many Bell tests have been performed, and loopholes related to locality and detection have been closed in several independent experiments. It is still possible that a first event could influence a second, but the speed of this hypothetical influence (Einstein's 'spooky action at a distance') would need to be defined in some universal privileged reference frame and be greater than the speed of light. Here we put stringent experimental bounds on the speed of all such hypothetical influences. We performed a Bell test over more than 24 hours between two villages separated by 18 km and approximately east–west oriented, with the source located precisely in the middle. We continuously observed two-photon interferences well above the Bell inequality threshold. Taking advantage of the Earth's rotation, the configuration of our experiment allowed us to determine, for any hypothetically privileged frame, a lower bound for the speed of the influence. For example, if such a privileged reference frame exists and is such that the Earth's speed in this frame is less than 10-3 times that of the speed of light, then the speed of the influence would have to exceed that of light by at least four orders of magnitude.. back |

'A large number of complex networks is scale free - that is they follow a power law degree distribution. Here we propose that the emergence of scale-free networks is tied to the efficiency of transport and flow processing across these structures, In particular we show that for large networks on which flows are influenced or generated by gradients of a scalar distributed on the nodes, scale free structures will ensure efficient processing, whereas structures that are not scale free, such as random graphs, will become congested.'. back |

Patricia McCormick, The Girl in the Kent State Photo, ' That photo, of her kneeling over the body of Kent State University student Jeffrey Miller, is one of the most important images of the 20th century. Taken by student photographer John Filo, it captures Mary Ann’s raw grief and disbelief at the realization that the nation’s soldiers had just fired at its own children. The Kent State Pietà, as it’s sometimes called, is one of those rare photos that fundamentally changed the way we see ourselves and the world around us. Like the image of the solitary protester standing in front of a line of tanks in Tiananmen Square. Or the photo of Kim Phuc, the naked Vietnamese girl fleeing the napalm that has just incinerated her home. Or the image of Aylan Kurdi’s tiny, 3-year-old body facedown in the sand, he and his mother and brother having drowned while fleeing Syria.' back |
Paul Baumann, The Beauty of the Incomprehensible
Karen Kilby on the limits of theology, ' The book’s concluding essay, “Beauty and Mystery in Mathematics and Theology,” is an eye-opener for anyone who thinks mathematics is solely about exacting calculations, measurement, manipulation, and control. Kilby explains that the field of “pure” mathematics does not describe the natural world, nor is it of practical use to the engineer or scientist. It is about “beauty.” In that sense—and in its exploration of the ungraspable concept of infinity—it is analogous to the work done by theologians, which also should be valued for its beauty. Like the God who reveals himself yet remains hidden, pure mathematics cannot deliver any final answers. “One of the most striking features of some of the best of pure mathematics—one thing which makes it beautiful—is the way in which it confronts us with that which exceeds our control, the way it opens up to us things which are beyond our ability to comprehend,” Kilby writes. Pure mathematics enables practitioners to describe with greater and greater clarity and beauty what is finally incalculable and unknowable about the nature of numbers and thus reality. I’ll take her word for it. A search for greater clarity, guided by humility and a sense of awe, is also how Kilby understands theology. It is a compelling vision, one that does not surrender either to an apophatic reticence or to a complacent orthodoxy.' back |

Russell Shorto, The woman Who Made van Gogh, ' In 1905, she arranged a major exhibition at the Stedelijk Museum, Amsterdam’s premier modern-art showcase. She reckoned that it was time for a grand statement. The success she had had in promoting her brother-in-law’s art boosted her self-confidence. As more and more people in the field came to agree with her assessment of Vincent, she shed her youthful hesitancy. Rather than hand over the task of organizing the show, she insisted on doing everything herself. She rented the galleries, printed the posters, assembled names of important people to invite, even bought bow ties for the staff. Her son, Vincent, now 15, wrote out the invitations. The result was, and remains, the largest-ever van Gogh exhibition, with 484 works on display. back |
