I want to be a rock star theologian, an impossible dream for my mother's sake who believed every word the priests and nuns told her. She is dead now, and gone. Not in heaven, because they lied to her, the shonkiest pack of deluded salespersons that ever walked the Earth. The opening salvo, I hope, is the ?? essay which will contrast the Aboriginal Australian scientific theology with the dreams of Constantine, closing the circle that began with the Christian invasion of Australia. Stop.

Weyl; Space, Time Matter. Raum, Zeit, Materie 1921. Hermann Weyl

Weyl page xiii: ' Abbildung which signifies representation is generally rendered equally well by transformation, inasmuch as it denotes a copy of certain elements of the space mapped out on, or expressed in terms of, another space.' Overlooking [to some degree] the meaning of representation I now understand in the light of the slogan 'Information is physical'.

[page 185]

Weyl page 2: 'The ideas to be worked out in this book are not the result of some speculative inquiry into the foundations of physical knowledge, but have been developed in the ordinary course of the handling of concrete physical problems, problems arising in the rapid development of science which has, as it were, burst its old shell, now become too narrow'

page 5: ' We are only concerned in seeing clearly that the datum of consciousness is the starting point at which we must place ourselves if we are to understand the absolute meaning as well as the right to the supposition of reality.' What is an "absolute meaning"? A contradiction in terms since a meaning is a relationship or bond between two elements. My meaning is established by my relationship to the universe, my god, a real relationship as Aquinas claims for the relationships in the Trinity, ie substantial, not accidental. In truth there are no accidents in the old sense of elements unrelated to substance, ie colour [nature is substantially true to itself].

' It is of the nature of a real thing to be inexhaustible in content.'

' Time is the primitive form of the stream of consciousness. . . . "being now" ' [true of the cognitive consciousness of the differentiated divinity].

page 6: '. . . space is the form of the external world. That is to say every material thing can, without changing content, equally well occupy a position in space different from its present one.' Nevertheless changing its relationship to other things.

' The new solution of the problem of amalgamating space and time offered by the theory of relativity brings with it a deeper insight into the harmony of action in the world.' Let us say that all action is communication, requiring coordinated (tuned) transmitter and receiver. "Tuning" = "codec".

[page 186]

Weyl page 7: cycle = clock

page 8: A very bad argument: ' in consequence of the homogeneity of the continuum' since there is no continuum, but there are identical particles [made possible, for fermions, by discrete locations in space].

'An essential feature of measurement is the difference between the "determination" of an object by an individual specification ["address"] and the determination of the same object by conceptual means ["formal content"].' The next extension required of general covariance is to realize that "individual perceptions" and "conceptions" are equally events, that is the transmission of messages in a cognitive cosmos [is a measurement].

page 9: Every source is the local "coordinate system" for all the messages it sends and receive, but sources are grouped into linguistic groups insofar as they share codecs, ie they are members of a [mathematical] group.

page 11: Space is a symmetry, but in reality all symmetries are broken.

page 12; ' Starting from the conception of translation I shall then develop Euclidean geometry along strictly axiomatic lines,' Yielding a formal space that may or may not be real.

page 16; ' the intuition of continuity' arises from increased numbers of points, but quantization of universe tells us that only logical continuity is true.

page 17: vectors: linear space / dimensionality, n + 1 vectors in an n dimensional space are linearly dependent on one another, an expression of requisite variety.

[page 187]

Weyl page 20: 'All coordinate systems are equivalent in affine geometry.'

page 22: ' The conception of linear transformation thus plays the same part in affine geometry as the concept of congruence in general geometry.'

page 27: From affine geometry to metrical geometry.

page 28: ' . . . not the length but the square of the length of a vector depends in a simple way on the vector itself; it is a quadratic form. This is the real content of Pythagoras' Theorem,' scalar product.

page 33: Tensors ' "Tensor calculus" . . . will enable us to express in a convenient mathematical form not only geometrical laws but also physical laws.'

page 43: 'As natural phenomena take place in a metrical space the tensor calculus is the natural mathematical instrument for expressing the uniformity underlying them.'

We are thinking the fundamental processes in the universe take place in a logical rather than a numerical space because the space-time / momentum-energy metrics in metrical space are connected by the uncertainty principle Δt.ΔE = j etc which seems to be orthogonal to space-time, ie not coupled to it [ie the uncertainty operates between energy and time /space and momentum]. Physicists generally devise a mathematical symmetry like affine space and then break the symmetry when necessary to conform to data. The preferred mathematical symmetry here is the transfinite logical network and then we constrain it with computable functions like the unitarity we find in quantum mechanics and the Minkowski and Einstein metrics we find in space-time.

[page 188]

Weyl page 107: '. . . we shall make the sole assumption about space that it is an n-dimensional continuum.

page 104: ' One here uses the extremely fruitful mathematical device of making a problem "linear" by reverting to infinitely small quantities.' Good try, but not really permissible in a world of quantized dynamics.

page 218: '. . . the problem of centrifugal force has always been felt to be an unsolvable enigma.'

page 273: We use reference frames to assign numbers to points in space and then we use a model or theory to relate these numbers to one another and the general covariances instituted by tensor calculus enables us to eliminate the influence of arbitrary choice of reference system.

page 284: We may think of space-time as a network and the rest of physics (matter) as messages on this network. Wehl introduces little of quantum theory, fermions, bosons etc.

' Descartes dream of purely geometrical physics seems to have attained fulfilment in a manner of which he could certainly have had no presentiment.' and the introduction of quantum mechanics moves us from geometrical physics to logical physics which we wish to use to explain the transition from initial singularity to 4D spacetime.

page 285: '. . . the quantity of action is a pure number. But this is only as it should be if the theory is to be in agreement with the atomic structure of the world, which according to the most recent results (Quantum Theory) carries the greatest weight.'

[page 189]

Weyl page 311: ' We must here state in unmistakable language that physics at its present state [1950?] can in no way be regarded as lending support to the belief that physical nature is founded on rigorously exact laws. The extended field, "aether" is merely the transmitter of effects and is of itself powerless; it plays a part that is in nowise different from that which space, with its rigid Euclidean metrical structure plays according to the old view; but now the rigid motionless character has been transferred into one which gently yields and adapts itself. But freedom of action in the world is no more restricted by the rigorous laws of field physics than it is by the laws of Euclidean geometry according to the usual view.'

My entries in this notebook are as often concerned with my feelings as they are of any progress I have made in my intellectual pursuit. This seems reasonable to me since the evidence for my work comes from both my experience and the large volume of material that I have read since my theological career began in the sixties. Also I see my mind as a jungle which probably contains many of the answer to the questions I ask but have to find them by looking around because they do not always bubble spontaneously to the surface. As I have gone closer and closer to the idea of cognitive cosmology I have also come to see physics and psychology as merging so that [looking at] my own mind becomes to some extent a source of ideas and evidence for my position, a sort of second person within me.

From a statistical point of view the job is a bit like buying a lottery ticket, or perhaps a lottery ticket every day. If I can make my ideas stick the long term effect would be enormous, the billion dollar prize, but on the other hand the chances of success are very small. I'd hate to estimate how small, but I am hopeful and I am getting the story out to a few people every day, so maybe I am making some progress.

The issue now is to get from quantum mechanics to general relativity, maybe via special relativity, whose fundamental features are the velocity of light and the Minkowski metric. Following the ancient psychological model of the Trinity, we might see the first step in this process as the establishment of an 'atom' of communication comprising two sources (fermions) Father and Son and a link between them (bosons) the Holy Spirit. We identify the initial singularity as a quantum of action, and say it is pure act, following Aristotle's model of the unmoved mover and Aquinas' model of god. Since the initial singularity stands alone and we only assign properties to the elements of the universe through their relationships to one another, we can also accept the ancient notion that it is absolutely simple. We can also accept, given our experience of energy bubbles in accelerator experiments, that the singularity can differentiate into energy, time and a mix of particles, as we speculate happened in the big bang. Since we see the universe as beginning simple and complexifying, and the photon as the simplest particle, whose spin is one quantum of action, we may see the photon as the primordial particle whose

[page 191]

differentiation leads to the population of fundamental particles that we have identified in the last century of physical experimentation. In the trinity the self interaction of the Father creates the Son. In physics we are led to conclude that the self interaction of the initial singularity creates the universe, in some way acting as a "time reversed black hole" (Hawking and Ellis). Hawking & Ellis: The Large Scale Structure of Space-Time

Given this framework, let us explore the general outlines of the creation of the universe within the framework of cybernetics and particle physics, feeling for an axiomatic version of creation that is consistent with the earliest phases of the "big bang", the emergence of quantum theory and general relativity by a process that is essentially isolated, since it is all that there is and the only constraint that can possibly [guide] its behaviour is local consistency. Our first step is to use the consistency constraint on formal mathematics to build a mathematical tool for our task which I call a transfinite logical network, beginning with the simple foundation of computation, Boolean algebra.

Action, eternity, energy, time

Every computation is in effect a proof. The multiplication algorithm, for instance, guarantees that its conclusion truly represents the products of the numbers input [all other things being equal!]

[page 193]

A real key is that reality comes from below rather than from above, as we can see in the universe.

Multiple copies of god will create space [as the Trinity must do if it is to be consistent]. How does this relate to the no cloning theorem? [they will all be different, subsequent ones superposed with their predecessors?]. No cloning theorem - Wikipedia, Shield of the Trinity - Wikipedia

Energy is the rate of multiplication of quanta of action, the rate of multiplication of god.

One of my deepest and most ineradicable beliefs is my native language, and the only way to change this to even a small degree is to replace it with another language and never use it again. This is not really possible because of the enormous tacit cultural foundation upon which the language is built. Michael Polanyi; The tacit Dimension

Wake in fear. What is happening to my world? I am old and safe, wrapped in the wooly welfare state but what about my children and grandchildren? The only thing I can do from my armchair is what Einstein did, totally turn our understanding of our place in the world upside down. We are not the children of a caring omnipotent and omniscient God who loves us so much that they died for us and will not see us come to harm. No, we are part of the world ruled by our own nature and the nature of the world and our salvation does not depend on some hoped for magic but must be based on a cool and comprehensive scientific understanding of our situation.

[page 193]

A particle is a thing, a quantum of memory with both essence and existence, representing a particular action in the overall process of which it is part.

Quantum continuity is very much like logical continuity. The equation <χ|φ> = ∑i <χ|i><i|φ> treats the complete set of basis states |i><i| as a set of memories which are 'written into' by |φ> and 'read out of ' by <χ|[a complete basis is like Aristotle's "middle term"].

Hilbert on the axiomatization of physics, which must be possible because all of physics derives from the initial singularity. In the Beginning was the Act. (Gray, in Carlson, Jaffe & Wiles (eds) page 23) Hilbert's sixth problem. Carlson, Jaffe & Wiles: The Millennium Prize Problems

Jeremy Gray page 24: ' [Hilbert] argued in favour of rigour on the grounds of simplicity, and extended his requirement as far as geometry, mathematics, mechanics and even physics.'

The quantum of action per se in its eternal (ie formal) form is massless since energy, which creates mass, requires frequency, so in effect the eternal symmetry of action is broken by the bifurcation of energy and time expressed by the equation h = E/f. Like most of my momentarily brilliant / brief ideas this may not lead far but is my first contribution to the seventh millennium prize problem by completely rewriting quantum field theory in terms of evolution constrained by the transfinite logical network.

The creative system: The initial singularity multiplies without limit and at random, creating random superpositions. Some of these are computable, some not. Of the computable, some are NP, some not. Those that are NP can be checked by P processes and become selected, others not. The randomness is a consequence of the absence of control established by incomputability and the lack of requisite variety. Checkability is equivalent to reproducibility, that is capable of surviving in the computable ecosystem of the universe. This is the general plan, to be cleaned up by discussions of control representation and computation. All this [leads to] the section of evolution and creation [in the essay [principia theologica].

The transition from amplitude space to real space is a bit like the transition from dreaming sleep to wakefulness.

Algorithmic information theory is the foundation of symmetry [because an algorithm is a symmetry, essentially unchanged by instantiations; action is the fundamental algorithm of the universe].

page 3: instrumentalism vs understanding: why is an unpredictable roulette wheel fair?

page 4: Weinberg: 'The important thing is to make predictions . . . it is simply doesn't matter whether we ascribe these predictions to physical effects or gravitational fields or the motions of photons or to the curvature of space and time.'

page 5: ' . . . the physical world is an oracle.'

page 7: 'The deeper an explanation is the more remote from immediate experience are the entities to which it must refer.' Spoken like a mystic or a theologian. These entities are part of the fabric of reality.

Let us say that wilderness is the most peaceful form of existence, maximum entropy, so the god / universe is wild, uncontrolled by anything but itself. Entropy increases in two ways a) by uncontrolled randomness and b) by controlled reproduction [of discrete entities]. So we can imagine the invention of photons and electric charge (a form of communication) followed by reproduction of charged particles and photons, an early form of the bifurcation into fermions and bosons and the elements that give structure to space.

Invisibility: a fully occupied system has no time for idle talk:

[page 197]

try interviewing a fighter in the middle of a fight, the distraction will cause them to lose. So it is with the basic functions of the universre - they do not have time to talk until their motions are stopped by meeting another system / communicating with another system and emitting a fixed message, a photon or a particle, both of which are eternal, ie immutable [while they last].

Back to Deutsch:

page 32: ' . . . shadows . . . reveal the existence of parallel universes.'

page 33: 'Invisibility is one of the more straightforward properties of light.'

We only see the result of a computation when the machine halts, that is finishes the computation it is working on and turns its resources to communicating the result to its environment.

page 35: 'Attenuation of light eventually reveals quantization, ie individual photons, ie quanta of action with certain embodied properties, energy and polarization packed in one planck quantum.

page 41: Interference and the n-slit experiment, leading to Feynman's path integral . . ..

page 43: 'tangible' vs 'shadow' photons.

page 44: 'Thus we have inferred the existence of a seething prodigiously complicated hidden world of shadow photons.' You wish. Read Feynman.

[page 198]

'It seems that reality is much bigger than it seems, and most of it is invisible [but should show gravitationally if it is real!].

Deutsch page 45: So shadow particles are a parallel universe, QED for D!

page 46: 'Single particle interference experiments . . . show us that the multiverse exists and that it contains many counterparts of every particle in the tangible universe.' Or maybe it shows that quantum mechanics is non-local and pre-exists space-time.

'Shadow particles do not interact with tangible atoms.' BUT they do interact with tangible photons (??) Shadow barrier = shadow atoms.

page 47: 'The heart of the argument is that single particle interference phenomena unequivocally rule out the possibility that the tangible universe around us is all that exists.'

'The existence of the multiverse is still a minority view among physicists. Why? The answer, I regret to say, does not reflect well on the majority.'

Deutsch's problem is his understanding of superposition and the assumption that all the solutions to the wave equation are in some sense real, each one existing in its own universe. This is in a way a misunderstanding of algorithmic information theory that claims, for instance, that all possible instances of F = ma have simultaneous and equally real existence rather than potential existence. The initial singularity is potentially

[page 199]

the universe but it has taken it a while to grow to its potential size and the process is identical in principle to my growth from a single cell guided to become me by the algorithm represented by my DNA and my tacit constraints embodied in the properties of atoms etc.

Deutsch page 48: 'Quantum theory is about the interactions of the real with the possible.' and as Aristotle told us long ago, the possible becomes real by an act and that act in quantum language is measurement or observation. Spacetime exists because realities are becoming real at a rate determined by the local energy density.

page 49: D appears to overlook the role of potential in QM. We may think of a quantum of action as an active rather than passive potential, and perhaps taking Newton's third law into account, that real and potential exist in opposition to one another, rather like energy and time and momentum and distance, in each case separated from one another by a quantum of action Δx.Δp ≈ Δ E.Δt ≈ h.

. . .

page 51: 'The quantum theory of parallel universes . . . is not some optional interpretation . . .. It is the explanation – the only one that is tenable – of a remarkable and counter-intuitive reality.' Which is pure Platonic unrepresented bullshit!

page 52: 'Tangibility is relative to a given observer.' Sounds like the 'psychokinetic effect' rejected on page 50.

[page 200]

Deutsch page 68: Evolution of theory by variation and selection. Popper conjecture and refutation.

page 127: 'We know from the quantum theory that all . . . variables are quantized and therefore no matter how a computer works, the set of possible programs is discrete. Each program can therefore be expressed as a finite set of symbols in a discrete code or computer language. There are infinitely many such programs but each one can contain a finite set of symbols.' We need to distinguish strictly finite, countably infinite and uncountably infinite, ie introduce a transfinite computer network.

page 129: Contradiction in terms 'certain fixed set' ↔ 'infinitely large'

page 132: '. . . quantum computers can perform computations of which no (human) mathematician will ever, even in principle,be capable.' ?

page 134: '. . . the computing power of an abstract machine has no bearing on what is computable in reality,' So Turing is out the door!

page 135: 'The Turing Principle: It is possible to build a virtual reality machine whose repertoire includes every possible physical environment.'

We assume that this machine will model the universe at the quantum scale and will be built on the quantum scale, so the invisibility principe will apply to it because it will be fully occupied with doing its job so some sort of no cloning will apply and its only output will be itself. It suffers from what we might call fatal recursion and has the same problem as god creating the universe anew when

[page 201]

it already exists within them and (as we say) everything (like knowledge) which is accidental in created being is substantial in god so god's idea of the universe is both god and the universe.

Deutsch page 136: '. . . the laws of physics imply the physical existence somewhere in the multiverse, of entities that understand them arbitrarily well.'

page 141: '. . . there is one opposing theory – namely common sense – which requires me to refute in detail whenever it seems to conflict with what I am asserting.' Which seems to be pretty well everywhere!

page 142: 'There is indeed no logically necessary connection betwen truth and explanatory power.' So try that on explaining how an I[nternal] C[ombustion] engine works.

page 143: 'crypto inductivists should all be outed and purged, even if they are successful scientists.'

pages 144-166: proof that jumping off the Eiffel Tower is fatal.

Deutsch page 182: Control creates stable non-equilibrium systems ie (it would seem) keeps entropy down by selection. So on this counting I have lower entropy than the equivalent gas Perhaps we have to bring the time dimension into the calculation of entropy [or exploit the idea that higher layers in the system create exponentially higher entropy by constraining the entropy of the layers they are built on.

[page 203]

Deutsch page 224: 'when we have proven something, we know with absolute certainty that it is true' given the hypotheses of the proof. If these cannot be given a physical representation then the proof may be logical but fail, as we find with the circular proofs of analysis.

Deutsch page 242: D's virtual reality generators are digital and so cannot realize a perfect circle as imagined by the analysts, nor can the quantized universe.

page 222-257: Sounds like one of Donal Trump's incoherent raves. What he appears to be saying is that all his other universes serve as real representatives of things that are not represented and cannot be observed in this universe, so all his arguments have about the same validity as Aquinas' theological arguments which depend for premisses . . . on things which are allegedly 'per se nota' in the mind of god, who is, after all, a set of multiverses (ie three of them, the Trinity).

Deutsch page 277: Multiverse: 'A workable quantum theory of time - which would also be the quantum theory of gravity (?) - has been a tantalizing and unattainable goal of theoretical physics for some decades now (maybe via time, energy, gravity?). But we know enough about it to know that though the laws of quantum physics are perfectly deterministic at the multiverse level . . ..' ie (it seems) that the different multiverses are identical, superpositions at the amplitude level but they are different at the observational level, this accomodating the fact that quantum observations reveal different eigenvalues at random as determined by the Born Rule.

page 330: '. . . Everett's story is indeed one of an innovative young researcher challenging a prevailing consensus and being largely ignored [apart from publishing a book coauthored by some senior physicists] until decades later his view gradually becomes the new consensus.' in some little bubble. Hugh Everett III: The Many Worlds Interpretation of Quantum Mechanics

page 333: 'design' selection, variety, E-Theorem Asymptotic equipartition property - Wikipedia, Brockway Macmillan: The Basic Theorems of Information Theory

page 339: 'On the face of it, the price of understanding interference [superposition] phenomena is to create or exacerbate many philosopical problems.' For D, because he ignores Turing and Gödel and insists of determinism, completely ignoring requisite variety and the cybernetics of control.

So D has a good plan combining quantum theory, epistemology, computation and evolution but his story is seriously distorted by his ignorance of cybernetics, his insistence on determinism and the rather loony many world's solution to the quantum measurement problem. This book looks just the same to me as when I read it in 1997. Can I do any better while staying in the bounds of plausible representation?

[page 207]

So what is my answer to the measurement problem, ie the interface between the world of amplitudes and the world of observation, the interface between Hilbert and Minkowski space. Here's my try.

1. The quantum of action is a thing, identical to the Christian god, which we first meet in the initial singularity implied by general relativity. Hawking & Ellis: The Large Scale Structure of Space-Time

Because the universe started so simple, the explanation of the current structure must be simple. So three more axioms:

2. Pure action, by self reference, can try anything;

3. Requisite variety says such a simple beginning has no control, so these tries are random sequences of events (actions); and

4. Only sets of tries that form a group can explain their survival since the interaction of any two members of a group produces another member of the group.

The first group is the trivial one with one member whose interaction with itself produces itself. The second group is the energy group with two members. And so on.

This axiomatization of physics might make Hilbert happy. The sixth problem.Hilbert's sixth problem - Wikipedia

Star Wars Episode VI: The Return of the Jedi Return of the Jedi - Wikipedia

[page 208]

The upshot of the invisibility theorem is that we cannot see the basic processes of the universe [because they are too busy doing their thing to explain what they are doing] and the upshot of that is that we have to guess what the basic processes are by looking at the results [the "black box" problem"], and our answer to date is quantum theory in its various forms. Here I am inclined to replace quantum theory with a theory of virtual reality a bit like Deutsch based on my thing, the transfinite logical network, beginning from the idea that the foundation of physics is Boolean algebra embodied in a network.

There are two degrees of freedom in the computer network: the Turing machine it embodies and the processing rates or times of these machines. We wish to examine the spectrum of fundamental particles on this two dimensional space. The simplest particle is the photon, massless with an unbounded range of frequencies / energies. The fundamental question for the photon is how it can be highly energetic and massless, and the answer must be in its velocity and its momentum [closely related to velocity] that we see as prior to mass.

We understand quantum mechanics to be represented in a [countably] infinite dimensional Hilbert space and we use Fourier transforms to map between position and momentum representations φ(x) and ψ(p) of the wave function which has a shape determined by the superposition of each of the x and p basis states in the Hilbert space. Any function (more or less) can be represented by a Fourier series, so if we could translate a Fourier representation we would simplify things greatly.

[page 209]

So much of the difficulty of quantum theory arises from what may be a very wasteful representation of what is actually happening in an infinite function space when we might be able to do the same job with something much simpler and get rid of the infinites which are very unlikely to be represented by reality anyway.

So we have wave functions in momentum, position and energy space all interconvertible { ψ(p)}, {φ(x)} and {(c1, c2, . . . )] all of which are representations if a state vector | > and a space of kets in an abstract [Hilbert space] version of the three [representations]. Robert G. Littlejohn: Physics 221 A: Notes 1: The Mathematical Formalism of Quantum Mechanics

'A ray in Hilbert space is a one dimensional space of kets |ψ> related to a complex multiplicative factor c so to some non-zero ket |ψ0> so |ψ> = c|ψ0> so kets in a ray differ by normalization and phase.

Kets belong to a space Ε while bras belong to dual space Ε* of complex values linear operators called in mathematics forms, convectors or dual vectors.

Conversion if ket to bra requires metric.

Hilbert spaces have countable bases. Dirac: real or complexnumber is a c number; operator is a q number.

Cercignani, Carlo, Ludwig Boltzmann: The Man Who Trusted Atoms, Oxford University Press, USA 2006 'Cercignani provides a stimulating biography of a great scientist. Boltzmann's greatness is difficult to state, but the fact that the author is still actively engaged in research into some of the finer, as yet unresolved issues provoked by Boltzmann's work is a measure of just how far ahead of his time Boltzmann was. It is also tragic to read of Boltzmann's persecution by his contemporaries, the energeticists, who regarded atoms as a convenient hypothesis, but not as having a definite existence. Boltzmann felt that atoms were real and this motivated much of his research. How Boltzmann would have laughed if he could have seen present-day scanning tunnelling microscopy images, which resolve the atomic structure at surfaces! If only all scientists would learn from Boltzmann's life story that it is bad for science to persecute someone whose views you do not share but cannot disprove. One surprising fact I learned from this book was how research into thermodynamics and statistical mechanics led to the beginnings of quantum theory (such as Planck's distribution law, and Einstein's theory of specific heat). Lecture notes by Boltzmann also seem to have influenced Einstein's construction of special relativity. Cercignani's familiarity with Boltzmann's work at the research level will probably set this above other biographies of Boltzmann for a very long time to come.' Dr David J Bottomley

Lonergan, Bernard J, and Michael G Shields, Frederick E Crow (Editors), The Ontological and Psychological Constitution of Christ, University of Toronto Press 2002 Amazon Book Description 'Bernard Lonergan's De constitutione Christi was written to accompany a course being taught in Latin at the Gregorian University, Rome during the 1950s and 60s. This little-known treatise, volume seven in the series, is presented in English translation, accompanied by the original Latin text. Here, Lonergan tackles the metaphysical and psychological questions raised by the unique makeup of Christ, who is both fully human and fully divine, according to traditional Christian theology. His analysis falls into two parts: ontological and psychological. In dealing with the ontology of the incarnate Word, Lonergan explores the notion of person, and in doing so provides an interesting treatment of the existential question of personal authenticity raised by Kierkegaard and treated by Lonergan under the heading of Existez. Moving into his psychological analysis, he argues that consciousness is not a matter of introspection, a perception of oneself as object, but rather an awareness of oneself as subject. He then applies this understanding to the self-awareness of Christ, with particular reference to the question of Christ's knowledge of himself as both human and divine. This book is a foundational text in critical areas of contemporary theology; however, it was never widely circulated and has remained effectively unknown to contemporary scholars. With this translation the work will finally be made accessible'

Weyl, Hermann, Space Time Matter (translated by Henry L Brose), Dover 1985 Amazon customer review: ' The birth of gauge theory by its author: This book bewitched several generations of physicists and students. Hermann Weyl was one of the very great mathematicians of this century. He was also a great physicist and an artist with ideas and words. In this book you will find, at a deep level, the philosophy, mathematics and physics of space-time. It appeared soon after Einstein's famous paper on General Relativity, and is, in fact, a magnificent exposition of it, or, rather, of a tentative generalization of it. The mathematical part is of the highest class, striving to put geometry to the forefront. Actually, the book introduced a far-reaching generalization of the theory of connections, with respect to the Levi-Civita theory. It was not a generalization for itself, but motivated by the dream (Einstein's) of including gravitation and electromagnetism in the same (geometrical) theory. The result was gauge theory, which, slightly modified and applied to quantum mechanics resulted in the theory which dominates present particle physics. Weyl's unified theory was proved wrong by Einstein, and his criticism alone, accepted by Weyl and included in the book, would justify the reading. Though wrong, Weyl's theory is so beautiful that Paul Dirac stated that nature could not afford neglecting such perfection, and that the theory was probably only misplaced. Prophetic words! . . .

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

But new evidence suggests innate responses are changed by previous infections or vaccination, through “innate learning” or “trained immunity”.' back

Trinity - Wikipedia, Trinity - Wikipedia, the free encyclopedia, 'The Christian doctrine of the Trinity (from Latin trinitas "triad", from trinus "threefold") defines God as three consubstantial persons, expressions, or hypostases: the Father, the Son (Jesus Christ), and the Holy Spirit; "one God in three persons". The three persons are distinct, yet are one "substance, essence or nature" homoousios). In this context, a "nature" is what one is, while a "person" is who one is.' back

Unitary operator - Wikipedia, Unitary operator - Wikipedia, the free encyclopedia, ' In functional analysis, a branch of mathematics, a unitary operator . . . is a bounded linear operator U : H → H on a Hilbert space H satisfying UU* = U*U = I where U* is the adjoint of U, and I : H → H is the identity operator. This property is equivalent to the following: 1. U preserves the inner product ( , ) of the Hilbert space, ie for all vectors x and y in the Hilbert space, (Ux, Uy) = (x, y) and
2. U is surjective.' back

Variety (cybernetics) - Wikipedia, Variety (cybernetics) - Wikipedia, the free encyclopedia, 'The term Variety was introduced by W. Ross Ashby to denote the count of the total number of states of a system. The condition for dynamic stability under perturbation (or input) was described by his Law of Requisite Variety. Ashby says: Thus, if the order of occurrence is ignored, the set {c, b, c, a, c, c, a, b, c, b, b, a} which contains twelve elements, contains only three distinct elements- a, b, c. Such a set will be said to have a variety of three elements. He adds The observer and his powers of discrimination may have to be specified if the variety is to be well defined. Variety can be stated as an integer, as above, or as the logarithm to the base 2 of the number i.e. in bits.' back

Whitney Houston, I have Nothing,
'Don't make me close one more door
I don't wanna hurt anymore
Stay in my arms if you dare
Must a imagine you there?
Don't walk away from me
I Have Nothing
Nothing, if I don't have you
You see through
Right to the heart of me
You break down my walls
With the strength of your love
I never knew
Love like I've know it with you
Will our memories survive?
One I can hold on to
A don't really need to look
Very much further
I don't wanna have to go
Where you don't follow
I'm holdin' back again
This passion inside
Can't run from myself
There's nowhere to hide
You're the love I remember forever.
