Feynman Gravitation page 163: 'In general [cosmology] deals with all that can be known about what happens.' page 163 Feynman
The network model does not (at least initially) tell us anything new but it does (for me) make everything more comprehensible and provides a logical framework for making computations about events (modelling) Rather as Copernicus did for the solar system, producing a simple are more comprehensible explanation of planetary motion. Newton took the final step by finding a stationary point in the whole motion expressed in the law of Universal gravitation. The law we are looking for might be the law of requisite variety, which partitions the relationships between systems into controllable and uncontrollable.
To build is to establish fixed points by deriving them from other fixed points, in practical terms local unweathered rock.
DIVINE = OF UNBOUNDED COMPLEXITY
When all humans are equal they are also fully differentiated and equiprobable so that the entropy of the system is at a maximum, ie it has reached a complexity bound for that layers., Of course every element of this complexity may be a letter in the alphabet of the next layer of complexity.
Falling in love is the potential which creates the complex interlocking structure of life together, further complexified by interactions of families and children. The first bit of structure is the date, and if the potential is sufficiently deep, things will go on from there.
If gravitation is source free, we do not have any communication, since communication implies two sources? So gravitation lies in the first three axioms of quantum mechanics, and all the complexities only enter when we start splitting the universe into distinct particles.
Everything lives in its own proper time, by which we mean that a message is a 3-space moving through time, that is a timeless entity moving through time, in other words an algorithm or Turing machine.

GRAVITATION <==> CLASSICAL GOD (HEBREW)
THE REST (currently described by field theory) <==> TRINITY
Feynman page 216: 'Just as in the quantum mechanical case, we shall find that the emitter of the radiation is also the stress.'
The basis motivation of communication is internal consistency which can be cured by communication. So we might have two classes of internal inconsistency (error): those that can be corrected locally; and those that require the help of an oracle (the environment) which is obtained by communication, question and answer.
Current = communication channel. The channel is the message, different channel, different message. This is the physical level of abstraction. Later we see the same channel carrying different messages as with photons and the spectrum of momenta.
Still floating free, not connected. I was disconnected when I left the Order of Preachers and have remained a (theologically) free particle since then. Trying quite hard to connect god to physics via communication, or more specifically through the notion that the universe, like god, fills not just physical but noetic space, whose phase space is the symmetric universe. At the physical level all transitions in this universe are wrought by 'currents' of communication. I am seeking to solve enough of my internal inconsistency to begin communicating theologically again.

Cosmological principle: each of us (and every particle) is at the centre of its own universe, in its proper self, partly expressed as an inertial frame.
Feynman page xxxii: 'What I cannot create I cannot understand'/
Massless spin-2 field may be interpreted as a metric.
'Hence it appears that Feynman's intuition about the connection between geometry and gauge invariance is correct.

Books
| Galilei, Galileo, Dialogues Concerning Two New Sciences (translated by Henry Crew and Alfonso de Salvio) , Dover 1954 Jacket: 'Despite the fact that this book encompasses thirty years of highly original experimentation and theorizing on the part of this singular man, it is eminently readable. Written as a discussion between a master and two students, it sets forth its hundreds of experiments and summarizes the conclusions Galileo drew from these experiements in a brisk direct style. Using helpful geometric demonstrations, Galileo discusses aspects of fracture of solid bodies, cohesion, leverage, the speed of light, sound, pendulums, falling bodies, projectiles, uniform motion, accelerated motion, and the strengths of wires, rods and beams under different loadings and placements. Not only does the book display the genius of one of the makers of our civilization, but it also presents, for the historian of science, considerable information about Renaissance misapprehensions which Galileo refuted.'

| Heisenberg, Werner , Physical Principles of the Quantum Theory (translated by Carl Eckart and Frank C Hoyt), Dover 1949 Jacket: 'In this classic, based on lectures delivered at the University of Chicago, Heisenberg presents a complete physical picture of quantum theory. He covers not only his own contributions, but also those of Bohr, Dirac, Bose, de Broglie, Fermi, Einstein, Pauli, Schroedinger, Sommerfeld, Rupp, Wilson, Germer and others in a text written for the physical scientist who is not a specialist in quantum theory or in modern mathematics.'

| Hofstadter, Douglas R, Goedel Escher Bach: An Eternal Golden Braid, Basic/Harvester 1979 An illustrated essay on the philosophy of mathematics. Formal systems, recursion, self reference and meaning explored with a dazzling array of examples in music, dialogue, text and graphics. Amazon back |

| Gaarder, Jostein, and Paulette Moller (Translator), Sophie's World: A Novel About the History of Philosophy, Boulevard 1996 Amazon editorial review: 'Wanting to understand the most fundamental questions of the universe isn't the province of ivory-tower intellectuals alone, as this book's enormous popularity has demonstrated. A young girl, Sophie, becomes embroiled in a discussion of philosophy with a faceless correspondent. At the same time, she must unravel a mystery involving another young girl, Hilde, by using everything she's learning. The truth is far more complicated than she could ever have imagined.' An excellent essay on the relationship between literature and reality. Amazon back |
| Galilei, Galileo, and Stillman Drake (Translator), Albert Einstein (Foreword), J L Heilbron (Introduction), Dialogues Concerning the Two Chief World Systems, Modern Library 2001 Jacket: 'Galileo's Dialogue Concerning the Two Chief World Systems' published in Florence in 1632, was the proximate cause of his being brought to trial before the Inquisition. Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernical system over the Ptolemaic one, proving for the first time that the earth revolves around the sun.'

| Philo, and F H Colson and G H Whitaker (translators), Volume II. On the Cherubim. The Sacrifices of Abel and Cain. The Worse Attacks the Better. On the Posterity and Exile of Cain. On the Giants, Loeb Classical Library 1981 Jacket: 'The philosopher Philo was born about 20 BC to a prominent jewish family in Alexandria, the chief home of the Jewish diaspora and the chief centre of Hellenistic culture; he was trained in Greek as well as Jewish learning. In attempting to reconcile biblical teachings with Greek philosophy he developed ideas that has wide influence on Christian and Jewish religious thought.' Amazon back |

| Feynman, Richard, Feynman Lectures on Gravitation, Westview Press 2002 Amazon Editorial Reviews Book Description 'The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues. Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.' Amazon back |
