The history of creation is the foundation of my faith. It was not done by an omniscient creator but by a structureless omnipotent agent guided by consistency [in other words there was no plan, only omnipotent power constrained only by local consistency].
The basic constraint on quantum physics, identified by von Neumann, is the normalization of messages [from the world] in spacetime which means that a message is a random event that obeys the laws of probability.

My book is based on the idea that quantum computation and communication are at least as powerful as Turing digital computation and communication [and so can evolve software that distinguishes massive charged fermions from massless neutral bosons]. The problem is that while we can observe and measure discrete entities in Minkowski space like the impact of a photon on an atom and the emission of an electron (the photoelectric event) we cannot see the quantum details of this event [although we know it happens] and we must try to work out how it is actually happening by repeating the event a large number of times under different conditions. The result of this work has been quantum field theory which reveals very precise calculations on the assumption that there is a linear quantum operator at every point in continuous Minkowski spacetime, an assumption that leads to the plague of infinities that has dictated the mathematical structure of quantum field theory. The problem can be solved by the assuption that the mathematical continuity motivated by the Pythagorean theorem does not represent reality and we can cure this problem by placing quantum mechanics under rather than over Minkowski spacetime, assuming further that every event in the quantum world is a discrete [logical] event measured by the quantum of action and using this foundation to explain that the quantum origin of Minkowski spacetime is a consequence of the computational versatility of quantum mechanic whose founding distinction [the explanation of network communication] is the differentiation of bosons and fermions [which divides all fundamental particles into two disjunct categories].

My problem with navigating the real world is that one half of me is a tradesman working in the Minkowski world and the other half of me is working on physical theology which means quantum mechanics, a world of abstract formal logic, the world that Plato discovered where space and time do not exist. So yesterday I used a set of allen keys to dismantle a piece of furniture to get the material to make a barrier to stop kittens escaping. Today I have no idea where I left these allen keys [and suspect they have been moved by the cleaner].
Denialism is irrational but the world is guaranteed to be rational by the boundary of consistency placed on omnipotence. Aquinas, Summa I, 25, 3: Is God omnipotent?
The key to the whole story is the versatility of Hilbert space. Aristotle constructed his path from matter and form to the [cognitive] unmoved mover by the doctrine of potency and act. How do we reformulate this path in terms of Hilbert space and quantum mechanics? For Aristotle this idea probably grew round the agent intellect, separate, formal, intelligent and eternal and a clear foundation for Aquinas' model of God. In the book we use the doctrine of the Trinity as a starting point for this story and equate kinematic formalism to the potential and dynamic reality to action. Here we begin with [naked] gravitation which, like God, is pure dynamic action, driving the
[page 206]
formation of kinematic Hilbert space from which quantum mechanics, using something like the lagrangian and hamiltonian methods, selects stationary states represented by quanta of action using an analogue of the mathematics of variation. These fixed points are converted from kinematic to dynamic by the bifurcation of gravitation into potential and kinetic energy [and we wonder about the conditions determining the numerical value of this bifurcation, perhaps the mass-energy of the particles so formed]. Each time I formulate these ideas they have an emotional content which we imagine to be represented by density operators.

Quantum field theory is in effect a theology which guides the practical actions of 'priests' who manufacture space based instruments to show us how the Universe works. Some of this theology may have been a bit misguided, requiring human sacrifices and special networks, something that we see echoed in the industrial world of money and production,

Letter to Gerard O'Brien re MPhil.
The key hypothesis is that if the Universe is divine physics and theology have the same subject. Aristotle achieved this by expanding hylomorphism to the doctrine if potency and act which gave him tools to develop the separate and immortal agent intellect as the source of intelligence and the model for the psychological unmoved mover (Bordt. see above).
My idea is to give quantum mechanics the role in physics played by Aristotle's hylomorphism, show that linear operators in quantum mechanics play the role of Aristotle's agent intellect and use these ideas as the foundation of an idea I call cognitive cosmogenesis while avoiding the problems in quantum field theory by making Hilbert space prior to Minkowski space: Chapter 12: Is Hilbert space independent of Minkowski space? Synopsis: Jeffrey Nicholls (2025): Cognitive Cosmogenesis: a systematic integration of theology and physics
In this book I imagine a similar starting point and conclusion to the standard model of cosmogenesis but suggest an alternative creative process. The initial singularity is conceived as naked gravitation identical to the divinity modelled by Aquinas. The first structure to emerge in this singularity is the Hilbert space of quantum mechanics. This provides the formal variation necessary for evolution independent of the constraints of classical Minkowski spacetime. The quantum phenomena of non-location and entanglement show that this primordial process is free to discover kinematic fixed points. These structures derive energy from gravitation to become the elementary bosons and fermions that define Minkowski space. Local Minkowski spaces control the global structure of the Universe described by Einstein.
[I further suggest] that [quantum mechanics] has sufficient flexibility to describe democracy and politics" Chapter 27: The political consequence of physical theology:
Synopsis: Top down Catholicism claims to act with the infallible and omnipotent power of God to dictate to its followers. In 2000 years of consistent deception the Church has become a global descendant of the Roman Empire. An imperial picture. Here we work from the bottom up. A key to the connection of theology and physics is symmetry with respect to complexity. Although the difference in scale between fundamental particles and an ideal democratic polity is immense, they are formally quite similar. Democratic politics fits Hilbert space. Voting itself is linear, a form of superposition. Individuals and political parties are characterized by their directions in political space which may be modelled as vectors in a Hilbert space. Every person is represented by a basis vector and their sums in various combinations present us with a comprehensive picture of the political directions in an electorate. There seems to be fundamental harmony between democratic politics and the nature of the world.
We build the creation of the world around quantum mechanics, which provides the form, and gravitation which provides the action by bifurcating into potential and kinetic energy,
Cognitive Cosmologenesis is a memoir of my 60 years if experience with Catholic theology. My idea is to repeat the work of Thomas Aquinas who reformulated Christianity in the scientific language if Aristotle in his Summa Theologiae. My project, which I find rather exciting is to repeatg this reformulation using modern science and quantum theory to put theology on s sound scientific footing by uniting it to modern physical science.

Football: particles at work in an environment of photons. Every particle is a song; every song is a particle [a form made concrete by energy, analogous to Aristotle's notion of forms made concrete by matter: now in Minkowski space matter ≡ energy, energy ≡ quanta of action per time].

Inconsistent social, political and software systems lead to evil by annihilation of elements of the inconsistency. There is reality and there's politics. Politics is largely hypothesis (fantasy); reality is observable.
Re NMT ann 2024_1212_12: Developing an industrial process. My next step may be to write a paper comparing conventional axiomatic approach to quantum field theory built on the assumption that Minkowski space is the actual foundation of the Universe versus my version that places Hilbert space at the foundation and sees Minkowski spaced as a logical consequence of the quantum mechanical / gravitational production of Minkowski space through the formal quantum mechanical development of stationary states [to be understood as items of software] corresponding to bosons and fermions and raising of these states to the status of real observable particles [execution of actions] in Minkowski space by the bifurcation of gravitation into potential and kinetic energy. This establishment of local Minkowski space then feeds [executes] general relativity [by units of Minkowski space interacting with one another as in a differential manifold] to give us

Scale invariance of quantum mechanics is a consequence of linearity: Wigner: "It can in fact be shown that every state of any quantum mechanical system no matter what type of interactions are present, can be considered as a [scil: linear] superposition of states of elementary systems.

Quantum of action and Hamilton's principle. All events involve a complete quantum of action [ie = a full rotation on the polar complex plane]. New principles.
[page 210]
Field theory is one of the dimensions of continuity that have arisen from the Pythagorean theorem and the imagination of ancient mathematicians and the efforts by nineteenth century mathematicians to define real numbers to make calculus respectable.
Field is a delusion like the luminiferous ether and the continuity of Minkowski spacetime [which is pixellated by quanta].
All we need [in the Minkowski space where we live] are particles and messages, bosons and fermions. We take as a principle that all interactions require an integral number of quanta of action [just as all computations require an integral number of operations] which we take to be logical operators. How do we fit these into quantum mechanics? Fixed points and Hamilton's principle [which are in effect built into quantum theory by its logical structure].
In other words we modify Feynman's path integral with Hamilton's principle to get an integral number of quanta, 1 [per completed] elementary event.
The big deal is that quantum mechanics predates space and time and deals only in formal logic. This logic is operated by the structure of naked gravitation generated by fixed point theory. So the plan: write a paper on the alternative to QFT and get a prof to submit it to arXiv and then show how it upstages QFT.

Wigner: Invariance in physical theory: The invariances is Minkowski space are consequences of the invariance in quantum mechanics which is basically rooted in the integral nature of logical quantum mechanics. Gauge theory is built around phase but the phases in actual interactions are all measured mod 2π. The rational values attributed to phases in gauge theory are not intrinsic to the action but are a consequence of the probability of interaction computed by something like Feynman's path integral [and Feynman diagrams].

A lot of stuff exists in my mind in forms other than words so sometimes the conversion from thought (the quantum world) to words (the Minkowski world) can be a bit slow, leaving me speechless or unable to make sense of what I am hearing or reading.

More phone: The effect of the approach explained in Streater and Wightman (page 96): 'Since in quantum mechanics observables are represented by hermitian operators which act on the Hilbert space of state vectors one expects the analogue in relativistic quantum mechanics of a classical observable field to be a set of hermitian operators defined at each point in spacetime and having a well defined transformation law under the appropriate groups.' The effect of this approach is to import the complexities of special relativity into quantum mechanics which in itself has nothing to do with space and time. Streater & Wightman (2000): PCT, Spin, Statistics and All That"
[The consequence of this is noted by Veltman (page 20): ' Thus corresponding to a Lorentz transformation there is a complicated, big transformation in Hilbert space. Martinus Veltman (1994): Diagrammatica: The Path to the Feynman Rules]
[Veltman's description of Hilbert space, page 33: 'A vector in Hilbert space represents a physical state. What is a physical state? A physical state is simply a physical situation with particles moving here and there, with collisions, with dogs chasing cats, with people living and dying, with all sorts of things happening.' This is in Minkowski space. What is it in Hilbert space? A linear operator represented by a density matrix?]
Werner Jaeger Aristotle Werner Wilhelm Jaeger (1997): Aristotle: Fundamentals of the history of his development
page 3: 'Aristotle was the first thinker to set up along with his philosophy a conception of his own position in history; he therefore created a new kind of philosophical consciousness, more responsible and inwardly complex.
I bought this book in 1070 and although I have been talking about Aristotle non-stop since the 60s, this seems to be the first time I have read it now that I have written a book reliving his path from logic and physics to metaphysics and theology, from detail to simplicity

page 4: cosmogenesis Aristotle: 'here and elsewhere we shall not obtain the best insights into things until we actually see them grow from the beginning.'
page 13: 'Aristotle made himself out of Platonic philosophy,'
' The Academy Aristotle entered in 367 was no longer that of the time of the Symposium, around whose table Plato in the full tide of his enthusiasm had imagined the leaders of art and science and the representatives of Hellenic youth gathered to hear from the lips of the prophets the great mystery of the birth of intellect out of Eros.' ie the birth of quantum mechanics from the lust for life of naked gravitation seeking orgasm and understanding, ie stationary points.
Density matrix can represent feeling, eg in sound [a superposition of a multitude of state vectors]. Girl from Ipanema Astrud Gilberto Astrud Gilberto, Joao Filberto, Stan Getz (1962): The Girl from Ipanema
Jaeger page 15: ' Plato's abstract and methodological period began about 369. This gave Aristotle a definite direction . . .
[page 215]
the early Plato was a reformer and an artist. In contrast to this, Aristotle's work was abstract, and his attitude was that of a pure scientist.' Really? Yes and No.
Jaeger page 16: Platonic forms: abstract (kinematic) entities (puppets) can only operate in the context of concrete (dynamic) entities. Naked gravitation, the initial singularity is both abstract and concrete [owing to its simplicity] or as Aristotle and Aquinas might say, it essence is its existence, it is a necessary being and ipso facto. eternal. It can be represented by an empty set, ∅ and be populated with stationary yet 'kinematic' points by fixed point theory. Every time I write this is get the world closer to the reality I seek. Aquinas, Summa, I, 3, 4: Are essence and existence the same in God?

[Phone:] Turing machines work in Minkowski space just as ordinary electronic computers do but the role of quantum mechanics in the computing and switching process is not specifically related to the computing process which could equally well be done, as it is in many applications, with relays.
Jaeger page 21: 'Fruitful and congenial as was the youthful Aristotle's experience of the strict and mathematical procedure of the various sciences
[page 216]
the impression made upon him by Plato's personality was the strongest of all' [historical reconstruction?]
Jaeger page 22: Aristotle saw, as clearly as Eudoxus that Plato, in his philosophical work, had welded together scientific discoveries, elements of myth and mysterious spiritual realities to which the eye of knowledge had never penetrated. . . . it was precisely the non-scientific elements of Plato's philosophy, that is, the metaphysical and religious parts of it, that left a lasting imprint on his mind.'
page 40: The author of the Eudemus [supposed to be Aristotle] had surrendered himself absolutely to this belief in another life, and to the corresponding viewa of the world and the soul.'
Like Plato in Phaedo, Aristotle in Eudemus attacked the materialistic view which is opposed to the doctrine of immortality.
A prima faciae case against the primacy of Minkowski space as the foundation of divinity is that it is material and the view has been established since time immemorial that divinity is immaterial [since it is not observable] and Aquinas used this idea to show that God is omniscient, perhaps harking back to the observation in de Anima that the agent intellect is immaterial thus sealing the connection between immateriality and the intellect. We might say that intellect and
[page 217]
knowledge are built into quantum mechanics by its linearity and the quadratic nature of Minkowski space rules it out as a venue for intelligence, [perhaps] destroying the view that Turing neural networks can be the foundation for articicial intelligence — Luke Munn: Luke Munn (2024_11_15): Friday essay: it’s ‘the intelligence age’, say tech titans – but information will not save us

The difficulty with writing is to produce a faithful representation of all the things running around in my head at a particular moment (now) which have to be sorter=d and ordered to give a close approximation. The quantum mechanical density operator we well suited to represent a piece of music or a state of mind as a superposition of all the possible stationary point encoded in a linear operator.
What we seek, as the foundation of my paper, is the two classes of operators corresponding to bosons and fermions. A question to be posed by my paper to AJ Philosophy. We may be able to pick this from some of the operators listed in Nielsen and Chuang. Nielsen & Chuang (2016): Quantum Computation and Quantum Information
What made the US great was [technology and] science but they may have abandoned that now. The plan is to start a new era y making theology scientific and removing the immense drag on humanity arising from ancient mythology which seems to be enjoying a renaissance [my book (in press) Cognitive Cosmology is designed to nip all this rubbish in the bud by showing that real theology and religion can only be based on the scientific hypothesis that the Universe is divine so that the physical sciences (physics, biology, psychology, sociology, archaeology etc) are the basic current and historical sources of observable information for theology].

Although the difference in scale between fundamental particles and the people of an ideal democratic polity is immense, they are formally quite similar. Both democratic politics and quantum electrodynamics work in Hilbert space. Voting is linear, a form of superposition distributed by parties.

Robert Beyer's 1955 English translation, which von Neumann reviewed and approved, is cited more frequently today than ever before. But its many treasures and insights were too often obscured by the limitations of the way the text and equations were set on the page.

He has also corrected a handful of typographic errors, revised some sentences for clarity and readability, provided an index for the first time, and added prefatory remarks drawn from the writings of Léon Van Hove and Freeman Dyson.

Albert Einstein (1905c), On a heuristic point of view concerning the production and transformation of light, ' The wave theory of light, which operates with continuous spatial functions, has proved itself splendidly in describing purely optical phenomena and will probably never be replaced by another theory. One should keep in mind, however, that optical observations apply to time averages and not to momentary values, and it is conceivable that despite the complete confirmation of the theories of diffraction, reflection, refraction, dispersion, etc., by experiment, the theory of light, which operates with continuous spatial functions, may lead to contradictions with experience when it is applied to the phenomena of production and transformation of light.
Indeed, it seems to me that the observations regarding "black-body" light, and other groups of phenomena associated with the production or conversion of light can be understood better if one assumes that the energy of light is discontinuously distributed in space.' back |

Aquinas, Summa I, 25, 3, Is God omnipotent?, '. . . God is called omnipotent because He can do all things that are possible absolutely; which is the second way of saying a thing is possible. For a thing is said to be possible or impossible absolutely, according to the relation in which the very terms stand to one another, possible if the predicate is not incompatible with the subject, as that Socrates sits; and absolutely impossible when the predicate is altogether incompatible with the subject, as, for instance, that a man is a donkey.' back |
Aquinas, Summa, I, 3, 4, Are essence and existence the same in God?, ' I answer that, God is not only His own essence, as shown in the preceding article, but also His own existence. This may be shown in several ways.
First, whatever a thing has besides its essence must be caused either by the constituent principles of that essence (like a property that necessarily accompanies the species — as the faculty of laughing is proper to a man — and is caused by the constituent principles of the species), or by some exterior agent — as heat is caused in water by fire. Therefore, if the existence of a thing differs from its essence, this existence must be caused either by some exterior agent or by its essential principles. Now it is impossible for a thing's existence to be caused by its essential constituent principles, for nothing can be the sufficient cause of its own existence, if its existence is caused. Therefore that thing, whose existence differs from its essence, must have its existence caused by another. But this cannot be true of God; because we call God the first efficient cause. Therefore it is impossible that in God His existence should differ from His essence.' back |
Art Jipson (2024_11_09), New Apostolic Reformation evangelicals see Trump as God’s warrior in their battle to win America from satanic forces and Christianize it, ' A growing movement believes President-elect Donald Trump is fighting a spiritual war against demonic forces within the United States. Trump himself stated in his acceptance speech on Nov. 6, 2024, that the reason that “God spared my life” was to “restore America to greatness.”
I have studied various religious movements that seek to shape and control American society. One of these is the New Apostolic Reformation, or NAR, whose followers believe that they are waging a spiritual battle for control of the United States. NAR is an offshoot of Protestant Christian evangelicalism.
NAR advocates claim they receive divine guidance in reconstructing modern society based on Christian spiritual beliefs. In 2015, an estimated 3 million adult Americans attended churches that were openly part of NAR. . . .
NAR emerged in the late 1990s when theologian C. Peter Wagner popularized the term “New Apostolic Reformation.” Wagner argued that God was creating modern-day apostles and prophets who would lead Christianity in remaking American society. . . .
The roots of the New Apostolic Reformation can be traced to the broader charismatic movement that sees spiritual forces as an active part of everyday life.
This view does not separate sacred experience from regular everyday life. For the much larger network of charismatic Christians and Pentecostal movements that emphasize a personal relationship with God, the world is full of the active presence of the Holy Spirit, spiritual gifts and direct divine experiences. . . .
The New Apostolic Reformation represents a significant development, blending charismatic practices with a strong emphasis on politics and cultural transformation.
However, a large majority of Americans disagree that society should be remade based on religious theology. Thus, for now, the NAR movement’s fundamental views about religion and government are starkly at odds with most Americans.' back |

Olha que coisa mais linda
Mais cheia de graça
É ela, menina
Que vem e que passa
Num doce balanço
A caminho do mar
Moça do corpo dourado
Do sol de Ipanema
O seu balançado é mais que um poema
É a coisa mais linda que eu já vi passar
Ah, por que estou tão sozinho?
Ah, por que tudo é tão triste?
Ah, a beleza que existe
A beleza que não é só minha
Que também passa sozinha
Ah, se ela soubesse
Que quando ela passa
O mundo inteirinho se enche de graça
E fica mais lindo
Por causa do amor
Look, such a sight, so beautiful,
So filled with grace,
It's her, this girl who comes and who passes,
With a sweet swing, on her way to the sea.
Girl with body of gold
From the sun of Ipanema,
Her swing is more than a poem,
Is a sight more beautiful
Than I have ever seen pass by.
Ah, why am I so alone?
Why is there so much sadness?
This beauty that exists,
This beauty that is not only mine,
That also passes by alone.
Ah, if she but knew,
That when she passes by,
The world smiles,

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 |
Cabadell, Le Quéré, Perters, Hauck, Pongratz, Friedlingstein & Andrew (2024_11_13), Global carbon emissions inch upwards in 2024 despite progress on EVs, renewables and deforestation, ' Carbon dioxide (CO₂) emissions from fossil fuels continue to increase, year on year. This sobering reality will be presented to world leaders today at the international climate conference COP29 in Baku, Azerbaijan.
Our latest annual stocktake shows the world is on track to reach a new record: 37.4 billion tonnes of CO₂ emitted from fossil fuels in 2024. This is an increase of 0.8% from the previous year.
Adopting renewable energy and electric vehicles is helping reduce emissions in 22 countries. But it’s not enough to compensate for ongoing global growth in fossil fuels.
There were also signs in 2023 suggesting natural systems may struggle to capture and store as much CO₂ in the future as they have in the past. While humanity is tackling deforestation and the growth in fossil CO₂ emissions is slowing, the need to reach an immediate peak and decline in global emissions has never been so acute. . . .
Our latest carbon budget shows global fossil fuel emissions continue to increase, further delaying the peak in emissions. Global CO₂ emissions continue to track in the middle of the range of scenarios developed by the Intergovenmental Panel on Climate Change (IPCC). We have yet to bend the emissions curve into the 1.5–2°C warming territory of the Paris Agreement.
This comes at a time when it’s clear we need to be reducing emissions, to avoid worsening climate change.
We also identified some positive signs, such as the rapid adoption of renewable energy and electric cars as they become cheaper and more accessible, supporting the march toward a net-zero emissions pathway. But turning these trends into global decarbonisation requires a far greater level of ambition and action.' back |
Christopher Shields (Stanford Encyclopedia of Philosophy b), The Active Mind of De Anima III 5 , ' After characterizingnous the mind (nous) and its activities in De Animaiii 4, Aristotle takes a surprising turn. In De Anima iii 5, he introduces an obscure and hotly disputed subject: the active mind or active intellect (nous poiêtikos). Controversy surrounds almost every aspect of De Anima iii 5, not least because in it Aristotle characterizes the active mind—a topic mentioned nowhere else in his entire corpus—as ‘separate and unaffected and unmixed, being in its essence actuality’ (chôristos kai apathês kai amigês, tê ousia energeia; DA iii 5, 430a17–18) and then also as ‘deathless and everlasting’ (athanaton kai aidion; DA iii 5, 430a23). This comes as no small surprise to readers of De Anima, because Aristotle had earlier in the same work treated the mind (nous) as but one faculty (dunamis) of the soul (psuchê), and he had contended that the soul as a whole is not separable from the body (DA ii 1, 413a3–5). back |
D. Fernández Gil et al (2024_11_14), Detection of an orthogonal alignment between parsec-scale AGN jets and their host galaxies, ' Abstract
The relationship between galaxies and their supermassive black holes (SMBHs) is an area of active research. One way to investigate this relationship is to compare parsec-scale jets formed by SMBHs to the projected shape of their kiloparsec-scale host galaxies. Here we analyse very-long-baseline interferometry (VLBI) images of active galactic nuclei (AGNs) and optical images of their host galaxies by comparing the inner-jet position angle in VLBI-detected radio sources with the optical shapes of galaxies as measured by several large optical surveys. In total, 6,273 galaxy–AGN pairs were found. We carefully account for the systematics of the cross-matched sources and find that Dark Energy Spectroscopic Instrument Legacy Imaging Surveys (DESI LS) data are significantly less affected by them. Using DESI LS data, with which 5,853 galaxy–AGN pairs were cross-matched, we find a weak but significant alignment signal (with P ≲ 0.01) between the parsec-scale AGN jet and the kiloparsec-scale projected minor axis of the optical host galaxy in sources with measured spectroscopic redshifts. Our results show that the observed source properties are connected over three orders of magnitude in scale. This finding points towards an intimate connection between a SMBH, its host galaxy and its subsequent evolution. back |
Density matrix - Wikipedia, Density matrix - Wikipedia, the free encyclopedia, 'In quantum mechanics, a density matrix (or density operator) is a matrix that describes an ensemble[1] of physical systems as quantum states (even if the ensemble contains only one system). It allows for the calculation of the probabilities of the outcomes of any measurements performed upon the systems of the ensemble using the Born rule. It is a generalization of the more usual state vectors or wavefunctions: while those can only represent pure states, density matrices can also represent mixed ensembles (sometimes ambiguously called mixed states).' back |
Ellie Martus & Fengshi Wu (2024_11_12), Authoritarian fossil fuel states keep hosting climate conferences – how do these regimes operate and what do they want?, ' For the third year in a row, the United Nations Climate Change Conference will be hosted by an authoritarian state that sells fossil fuels. This week the 29th “conference of the parties”, COP29, is being held in Baku, Azerbaijan. It follows COP28 in Dubai, the United Arab Emirates last year and COP27 in Sharm El-Sheikh, Egypt the year before that.
It’s concerning that a succession of authoritarian and fossil fuel-rich states have been selected to host international climate negotiations. It means we must pay extra attention to political influences on the talks and beware of greenwashing by the hosts.
The domestic politics of these states also shapes global supply chains of fossil fuels and critical minerals. This in turn directly affects Australia’s trade, economy and foreign policies.
There are now more authoritarian and hybrid regimes globally than there are democracies. So some basic understanding of how authoritarian states respond to climate change matters, for Australia and the rest of the world. . . .
As far as China goes, the global superpower is extending its geopolitical influence by helping developing countries access cheap renewable energy technologies from non-Western sources. This challenges the leading role of the US and the West in the field of international cooperation on climate change.
As COP29 gets underway, the potential for authoritarian states to shape the outcomes remains strong. Understanding how these regimes work, and what they want, is vital as they affect global cooperation on climate change.' back |
Enayat Nasir (2024_11_12), How the Taliban are seeking to reshape Afghanistan’s schools to push their ideology
, ' The Taliban takeover of Afghanistan in 2021 was a blow for education across the country – but especially for girls and women. Since then, the Taliban’s leaders have outlawed education for girls after sixth grade, expanded religious seminaries known as madrasas ninefold and reintroduced corporal punishment in schools.
Now, the Taliban are continuing their assault on education for both boys and girls by changing the curriculum in grades 1-12. They have already revised textbooks up to eighth grade, and they’re on track to finish the rest within months. After completion, the revised curriculum will go up for approval by the Taliban’s supreme leader and will likely be followed by swift implementation. The process is straightforward. The supreme leader of the Taliban controls education policy – including the curriculum. Once submitted to him, he has no reason to reject or delay the implementation.
As an educational policy scholar who pushed for educational progress in Afghanistan before the Taliban takeover, I believe these changes echo the tactics of the Soviet-backed regime in the 1980s to impose an ideology through textbooks. They also reflect the stifling climate of the 1990s, which promoted violence and suppressed critical thinking in education. By controlling education, the Taliban aims to instill their totalitarian and extremist religious-based ideology in young minds, ensuring their grip on power for generations to come.' back |

Francesca Teltscher Taylor (2024_11_13), Germany’s post-Holocaust moral remaking is being challenged by the rise of the far-right – and wars in Gaza and Ukraine, Review: Out of the Darkness: The Germans 1942–2022 by Frank Trentmann (Allen Lane)
' Current conflicts in Ukraine and Gaza (now spreading across the Middle East), have placed Germany in a difficult position, forcing it to reconsider its role in the world. A uniquely German sense of guilt and shame for the Holocaust “inseparably” ties the Israel-Palestine conflict to “Germany’s unquestionable solidarity with Israel”, writes Frank Trentmann, in his new book on the legacy of World War II in Germany.
Since Hamas’ attacks on Israel on October 7 2023, politicians have reiterated that Israel’s security is Germany’s “reason of state”. This makes criticism of Israel’s treatment of Palestinians in the occupied territories “an extremely sensitive matter”. Even Jewish critics of Israel’s government have been cancelled and criticised as antisemitic.
Following the second world war, Germany has focused on atoning for its role as perpetrator and collaborator and, while a NATO member, it has largely avoided playing a leading role in international conflicts. Russia’s invasion of Ukraine has forced Germany to reevaluate its foreign policy and emerge from national introspection in what Chancellor Olaf Scholz has called a “Zeitenwende”, or historical turning point.
Germany has been forced to consider the state of its army. Until last year, when it released its first comprehensive national security strategy, it had “no national security strategy, let alone a security council”. And at the end of 2022, it only had enough bullets for two weeks of fighting.
Trentmann’s impressive book, Out of the Darkness: The Germans 1942–2022 shows: “Germans define themselves through a critical confrontation with their past”.' back |

James M Tiedje et al (2022_04_19), Microbes and Climate Change: a Research Prospectus for the Future, ABSTRACT
Climate change is the most serious challenge facing humanity. Microbes produce and consume three major greenhouse gases—carbon dioxide, methane, and nitrous oxide—and some microbes cause human, animal, and plant diseases that can be exacerbated by climate change. Hence, microbial research is needed to help ameliorate the warming trajectory and cascading effects resulting from heat, drought, and severe storms. We present a brief summary of what is known about microbial responses to climate change in three major ecosystems: terrestrial, ocean, and urban. We also offer suggestions for new research directions to reduce microbial greenhouse gases and mitigate the pathogenic impacts of microbes. These include performing more controlled studies on the climate impact on microbial processes, system interdependencies, and responses to human interventions, using microbes and their carbon and nitrogen transformations for useful stable products, improving microbial process data for climate models, and taking the One Health approach to study microbes and climate change. back |

Justin Ellis (2024_11_12), How could Donald Trump target the LGBTQ+ community? Project 2025 is a ready blueprint for discrimination, ' Donald Trump’s victory in last week’s US election has sent shockwaves through the LGBTQ+ community, given the president-elect’s divisive rhetoric and demonisation of the trans community in particular.
There are fears a second Trump administration will have devastating effects for millions of LGBTQ+ people in the United States and beyond.
What could Trump do while in office? The Project 2025 policy manifesto provides some clues.
A blueprint for discrimination
Written by the Heritage Foundation, a conservative think tank, Project 2025 is a playbook for the next conservative president.
Join 200,000 Australians who get their daily news from The Conversation.
It contains input from more than 110 groups on key policy and personnel recommendations. The intention is to act quickly. It features a 180-day action plan that “includes a comprehensive, concrete transition plan for each federal agency”.
Trump sought to distance himself from the manifesto during the campaign. However, many of the contributors played roles in Trump’s first term in office. This includes Stephen Miller, who is expected to be named deputy chief of staff for policy in his second term. Miller’s group, America First Legal, has backed Project 2025.
In 2022, Trump also said of the Heritage Foundation plans:
This is a great group, and they’re going to lay the groundwork and detail plans for exactly what our movement will do and what your movement will do when the American people give us a colossal mandate to save America.
The Project 2025 manifesto advocates the removal of anti-discrimination policies that protect the LGBTQ+ community. According to the American Civil Liberties Union (ACLU), this means removing all federal regulations and rules prohibiting discrimination on the basis of sexual orientation and gender identity.
Specifically, Project 2025 aims to limit the application of a Supreme Court ruling protecting people from workplace discrimination on the basis of sexual orientation and transgender status. back |
Kate Scott (2024_11_12), The ‘Lost Boys’ of Gen Z: how Trump won the hearts of alienated young men, ' Generation Z was supposed to be a vanguard of progressive politics – more queer, ethnically diverse and environmentally conscious than previous generations. Spurred on by climate protests, racial equality campaigns and feminist movements, we were sold the vision that Gen Z could usher in a more progressive and equitable future.
So, how is it that Donald Trump was elected to a second term despite this cohort now having reached voting age? And how did he secure a larger share of voters under 30 than any Republican presidential candidate since 2008?
The answer may lie in Gen Z’s “Lost Boys”, as they’ve been dubbed by some in the media. . . .
In Trump, they see an outlet for their grievances – a figure who promises to restore the old order and give them the recognition they believe they deserve.
Despite the narrative that Gen Z is more progressive than previous cohorts, recent voting data tell a different story when it comes to young men. While the political leanings of Gen Z women have stayed steadily left of centre, Trump’s popularity among young men surged by 15 percentage points from 2020. . . .
If the future belongs to Gen Z, it’s clear this particular subset of young men is not ready to follow the same path as their progressive peers. For many “Lost Boys”, Trump is more than just a political figure – he is a symbol of empowerment in a world that increasingly leaves them behind.
As the political and cultural landscape continues to evolve, understanding this phenomenon isn’t just a matter of curiosity, but a key to addressing the needs of a generation still trying to find its place in a confusing world.' back |

Lara Jakes (2024-11_09), Trump Should Not Let Putin Claim Victory in Ukraine, Says NATO Official, 'A senior NATO military official suggested on Saturday that any peace deal negotiated by President-elect Donald J. Trump that allowed President Vladimir V. Putin of Russia to claim victory in Ukraine would undermine the interests of the United States.
In a wide-ranging interview on the sidelines of a European defense summit in Prague, Adm. Rob Bauer, the Dutch chairman of NATO’s Military Committee, said: “If you allow a nation like Russia to win, to come out of this as the victor, then what does it mean for other autocratic states in the world where the U.S. has also interests?”
He added: “It’s important enough to talk about Ukraine on its own, but there is more at stake than just Ukraine.”
Mr. Trump has said repeatedly that he could end the war in Ukraine in a day, without saying how. A settlement outlined by Vice President-elect JD Vance in September echoes what people close to the Kremlin say Mr. Putin wants: allowing Russia to keep the territory it has captured and guaranteeing that Ukraine will not join NATO.' back |
Luke Munn (2024_11_15), Friday essay: it’s ‘the intelligence age’, say tech titans – but information will not save us, ' “We have entered the Intelligence Age,” proclaimed Sam Altman, the chief executive of OpenAI, in September. “Deep learning worked,” he explained, and this breakthrough in learning from data will unleash a smart era in which the more data becomes available, “the better it gets at helping people solve hard problems”.
Altman joins other thought leaders, corporations like Google and Amazon, and organisations such as the United Nations and the World Economic Forum, in pinning humanity’s hopes on better information.
The logic is enticing. By harvesting all the world’s knowledge, AI models can locate patterns, make correlations, and offer data-driven “insights”. The optimal solutions to our biggest problems are needles in a data haystack, so finding them exceeds the limited human mind. It is up to technology like deep learning to “capture it all”, analyse or train on it – and then offer up the brilliant game-changing idea or most rational response. . . .
In the past five years, my research has explored how technologies construct knowledge – but also exploit emotion and amplify radicalisation. To understand the current political moment, we need to understand both the limits of reason and the power of unreason. . . .
Gaza is Exhibit B. Law for Palestine, a not-for-profit, youth-led legal organisation, has meticulously compiled a database with more than 500 instances of incitements to genocide.

Last week, South Africa filed its Memorial to the International Court of Justice, a key document in its case against Israel. Its evidence is detailed in more than 750 pages of text, supported by exhibits and annexes of more than 4,000 pages. . . .
And yet Israel’s assault on Gaza continues, with deaths mounting up. According to Al-Jazeera, some of the government’s kill lists are generated via big data analysis, a kind of AI-assisted genocide. . . .
But history suggests our crises and responses have always been shot through with the “irrational”, a darker mélange of emotional power, bodily violence and political will.

(See the entry on quantum mechanics.) In the last few years QFT has become a more widely discussed topic in philosophy of science, with questions ranging from methodology and semantics to ontology. QFT taken seriously in its metaphysical implications seems to give a picture of the world which is at variance with central classical conceptions of particles and fields, and even with some features of QM.' back |
Michael Bordt (2011), Why Aristotle's God is not the Unmoved Mover, ' The aim of this essay is to show that the view—popular among
certain philosophers and theologians—that Aristotle’s God is the
unmoved mover is incorrect, or at least leads to serious misunderstanding. In a nutshell: among other things, the project of the twelfth book of the Metaphysics is to determine what the first ousia is. This first ousia is not identified with God in so far as it is an unmoved mover, but in so far as it is the actual activity (energeia) of thinking. To put matters differently, the actual activity of the first ousia does not consist in moving anything. Its activity rather consists in the exercise of reason, in thinking. Since, however, thinking is without qualification the best activity, and since God is that being who just does engage in the best activity, the first ousia, in so far as it is the same as the activity of thinking, must be God. Thus we perhaps expect that, at the summit of ontology, God himself will be the object of this first philosophy. Metaphysics Λ meets such an expectation only in a very limited way.
The limitation is the following: that which, so to speak, stands at
the summit of metaphysics is not God, but the activity of reason.
While this activity is identified with God, it is not so identified directly or immediately, but only as mediated by way of the conception of the best possible life. The twelfth book of the Metaphysics thus provides to an even lesser extent than is usually assumed the outlines of a theology. By way of recompense, however, Aristotle offers us a truly breathtaking metaphysics.' back |

Nick Carter & Robyn Scott (2024_11_31), Victors in the race for emerging tech will determine future , ' It is often claimed that the birth of the printing press heralded the start of the modern era, allowing ideas from the scientific revolution to spread. But does that give us the whole picture?
For writer Yuval Noah Harari, for example, the evolution is far more complicated, as he argues that the printing press unleashed two centuries of conspiracy theories and fake news as well, leading to grotesque behavior like witch trials. And when the revolution in scientific and philosophical thought did eventually take place some 200 years later, it was only after our institutions were able to earn the trust of populations. . . .
The growing pace of technological change is making the challenge more dynamic every day. Meanwhile, generative AI has begun elevating technology to an “agent” that can be wielded without a human in the loop. Yet, the foundations of generative AI’s jaw-dropping capabilities remain shaky — it is, after all, trained on our colossal global stash of information, which is characterized by some reliable facts sitting atop a huge, unreliable core of bits and bytes. . . .
A pressing example of this — perhaps less than a decade away — is quantum computing, which will enable us to solve impossible mathematical problems. However, it will also bestow decisive advantage to those seeking to undermine the values of the free world. In a post-encryption world, much of what was secret will no longer be so. . . .
Collectively, emerging technologies are creating an unstable world, where we don’t clearly understand what national security looks like. Reform will require imagination and energy, as well as unpopular decisions. But the first duty of any government is to protect its population. And when our leaders confront these emerging technologies — which they must — it will be clear that they lie at the heart of national security, for better or worse.' back |
Oren Cass (2024_11_09), Trump Is About to Face the Choice That Dooms Many Presidencies, ' Mr. Trump will hear a lot of counterarguments from the affluent and influential class that builds its business model on underpaid, undocumented labor, especially in industries such as construction and hospitality, where he has personal experience, as well as in agriculture. . . .
Rebuilding the American industrial base is another issue that Mr. Trump has elevated to the top of the national agenda, but about which his instincts are sometimes torn. Policies including tariffs are one vital tool to encourage domestic investment. But so is giving a targeted boost to technologies or sectors that are of particular importance. The bipartisan CHIPS and Science Act has done just that for the manufacture of cutting-edge semiconductors ; since its passage in 2022, all five of the leading global chipmakers have committed to building advanced U.S. plants. . . .
“That chip deal is so bad,” Mr. Trump told the podcaster Joe Rogan, prompting the speaker of the House, Mike Johnson, to say he would pursue repeal. Many of Mr. Trump’s advisers will tell him to dispense with industrial policy and cut taxes instead.
But CHIPS is overwhelmingly popular, so much so that Mr. Johnson quickly walked back his comment. . . . Perhaps most important, these policies work and are already spurring huge investments and the creation of high-quality jobs. When the Taiwan Semiconductor Manufacturing Company announced last month that its first plant in Arizona is already achieving production yields better than those of factories in Taiwan, the free-market message began shifting from decrying the policy to denying that it deserved credit for the success.
Real investment in factories has more than doubled since President Biden took office; for the electronics industry, it has nearly quadrupled since the beginning of 2022. By comparison, Mr. Trump’s Council of Economic Advisers tried to show that his 2017 tax cut spurred investment but instead found an effect of zero, though other research has since suggested some limited gains. What the tax cut did produce was lower corporate tax bills, and C.E.O.s will push for a repeat. A golden age for America does not depend upon high stock prices and C.E.O. bonuses. It depends upon real investment. If Mr. Trump wants to deliver for the average American, his policies must focus on the latter — including effective policies that were initiated by his political opponents.' back |

The experimental results disagree with classical electromagnetism, which predicts that continuous light waves transfer energy to electrons, which would then be emitted when they accumulate enough energy. An alteration in the intensity of light would theoretically change the kinetic energy of the emitted electrons, with sufficiently dim light resulting in a delayed emission. The experimental results instead show that electrons are dislodged only when the light exceeds a certain frequency—regardless of the light's intensity or duration of exposure.' back |
