Fast moving classical variables can generate quantum mechanical behavior. We demonstrate how this can happen in a model. The key point is that in classically evolving systems one can still define a conserved quantum energy. For the fast variables, the energy levels are far separated, such that one may assume these variables to stay in their ground state. This forces them to be entangled, so that, consequently, the slow variables are entangled as well. The fast variables could be the vacuum (...) fluctuations caused by unknown super heavy particles. The emerging quantum effects in the light particles are expressed by a Hamiltonian that can have almost any form. The entire system is ontological, and yet allows one to generate interference effects in computer models. This seemed to lead to an inexplicable paradox, which is now resolved: exactly what happens in our models if we run a quantum interference experiment in a classical computer is explained. The restriction that very fast variables stay predominantly in their ground state appears to be due to smearing of the physical states in the time direction, preventing their direct detection. Discussions are added of the emergence of quantum mechanics, and the ontology of an EPR/Bell Gedanken experiment. (shrink)

Standard canonical quantum mechanics makes much use of operators whose spectra cover the set of real numbers, such as the coordinates of space, or the values of the momenta. Discrete quantum mechanics uses only strictly discrete operators. We show how one can transform systems with pairs of integer-valued, commuting operators $P_i$ and $Q_i$ , to systems with real-valued canonical coordinates $q_i$ and their associated momentum operators $p_i$ . The discrete system could be entirely deterministic while the corresponding (p, q) system (...) could still be typically quantum mechanical. (shrink)

It is put forward that modern elementary particle physics cannot be completely unified with the laws of gravity and general relativity without addressing the question of the ontological interpretation of quantum mechanics itself. The position of superstring theory in this general question is emphasized: superstrings may well form exactly the right mathematical system that can explain how quantum mechanics can be linked to a deterministic picture of our world. Deterministic interpretations of quantum mechanics are usually categorically rejected, because of Bell’s (...) powerful observations, and indeed these apply here also, but we do emphasize that the models we arrive at are super-deterministic, which is exactly the case where Bell expressed his doubts. Strong correlations at space-like separations could explain the apparent contradictions. (shrink)

Hawking particles emitted by a black hole are usually found to have thermal spectra, if not exactly, then by a very good approximation. Here, we argue differently. It was discovered that spherical partial waves of in-going and out-going matter can be described by unitary evolution operators independently, which allows for studies of space-time properties that were not possible before. Unitarity dictates space-time, as seen by a distant observer, to be topologically non-trivial. Consequently, Hawking particles are only locally thermal, but globally (...) not: we explain why Hawking particles emerging from one hemisphere of a black hole must be 100 % entangled with the Hawking particles emerging from the other hemisphere. This produces exclusively pure quantum states evolving in a unitary manner, and removes the interior region for the outside observer, while it still completely agrees locally with the laws of general relativity. Unitarity is a starting point; no other assumptions are made. Region I and the diametrically opposite region II of the Penrose diagram represent antipodal points in a PT or CPT relation, as was suggested before. On the horizon itself, antipodal points are identified. A candidate instanton is proposed to describe the formation and evaporation of virtual black holes of the type described here. (shrink)

A necessary refinement of the concept of circular reasoning is applied to the self-and-universally-referential inductive justification of induction. It is noted that the assumption necessary for the circular proof of a principle of induction is that one inference is valid, not that the entire principle or rule of induction governing that inference is true. The circularity in an ideal case is demonstrated to have a value of lin where n represents the number of inferences asserted valid by the conclusion of (...) the justifying argument, and the ‘I’ represents the inference necessarily assumed valid.An induction antinomy modeled after Russell’s antinomy of the set of all and only non-self-containing sets is derived. Isomorphic antinomies are noted to be derivable for other arguments of philosophical interest, including those purported to undermine theories of determinism, relativism, and skepticism, and including the one that Descartes reduced and converted to ‘Cogito, ergo sum’.

In the standard formalism of quantum gravity, black holes appear to form statistical distributions of quantum states. Now, however, we can present a theory that yields pure quantum states. It shows how particles entering a black hole can generate firewalls, which however can be removed, replacing them by the ‘footprints’ they produce in the out-going particles. This procedure can preserve the quantum information stored inside and around the black hole. We then focus on a subtle but unavoidable modification of the (...) topology of the Schwarzschild metric: antipodal identification of points on the horizon. If it is true that vacuum fluctuations include virtual black holes, then the structure of space-time is radically different from what is usually thought. (shrink)

A promising strategy for better understanding space and time at the Planck scale, is outlined and further pursued. It is explained in detail, how black hole unitarity demands the existence of transformations that can remove firewalls. This must then be combined with a continuity condition on the horizon, with antipodal identification as an inevitable consequence. The antipodal identification comes with a \ inversion. We claim to have arrived at ‘new physics’, but rather than string theory, our ‘new physics’ concerns new (...) constraints on the topology and the boundary conditions of general coordinate transformations. The resulting theory is conceptually quite non trivial, and more analysis is needed. A strong entanglement between Hawking particles at opposite sides of the black hole is suspected, but questions remain. A few misconceptions concerning black holes, originating from older investigations, are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Deep Mysteries: God, Christ, and Ourselves by Aidan NicholsGerard T. MundyDeep Mysteries: God, Christ, and Ourselves by Aidan Nichols, O.P. (Lanham, MD: Lexington, 2020), vii + 133 pp.Basic Catholic teaching declares that God's will must be trusted and that perfect knowledge of all that is resides in the Creator. An implication of this claim is that all of God's work within time and history—in man's linearly conception of (...) time and history—is meaningful. For, as perfect order himself God's work is neither random nor coincidental. God's perfect understanding means that he is able, colloquially speaking, "to connect the dots" perfectly. Thus, the historical particulars of the New Testament events are not random and coincidental, but they connect perfectly within God's plan.In terms of biblical events, then, what are the significances of the time periods during which, and places at which, they occurred? "Why was Jesus born on a particular date, at a particular time, and in a particular manger in Bethlehem? Why was the womb of Mary, Mater Dei, chosen at that exact time, and at that exact place? Why did Jesus stand on that particular mountain and not upon another? There are perfect answers to all of those questions and more, for, as Proverbs declares in this vein: "The LORD has made everything for a purpose" (16:4).In Deep Mysteries: God, Christ, and Ourselves, Father Aidan Nichols, O.P., meditates on questions related to the potential reasons for some of the historical particulars of "the principal Christological mysteries." Fr. Nichols defines the mysteries as these: "the Annunciation, the Nativity, the Baptism, the Transfiguration, the Passion and Death, the Descent into Hell, the Resurrection, the Ascension, Pentecost, and the Second Coming." (41).Attempting to understand how all of the parts of the New Testament fit together perfectly in an historical sense—as God's mind would see it—is a fascinating intellectual endeavor. The primary difference between the innocent inquirer and the vain one, however, is that the former understands that God's reason is infinite and that only the First Mover has the ability to see and to put together all particulars. Thomas Aquinas elucidates the essence of the endeavor to connect the particulars when, in reference to man's ability to understand "the truth of faith," he argues: "Yet it is useful for the human reason to exercise itself in such arguments, however weak they may be, provided only that there be present no presumption to comprehend or to demonstrate. For to be able to see something of the loftiest realities, however thin and weak the sight may be, is... a cause of the greatest joy" [Summa contra gentiles I, ch. 8).Posing the question of what the particulars of history might mean brings immediately another question. As Fr. Nichols asks: "How can the Eternal [End Page 386] and time be conjoined in a phrase, and the truth of such conjoining made credible?" (29). Indeed, if God transcends the man-conceived conception of time, how can man even understand God's movements if man can see time only in linear fashion? Fr. Nichols contends that Christ's "mystery-events are not just historical occurrences that, like all such events, belong to the human past" (31). Rather, argues Fr. Nichols, the mysteries "are permanently able to affect the intended beneficiary of the mysteries: namely, the human race" (31). In other words, contends Fr. Nichols, the mysteries are past, present, and future, in the human conception of time.Attempting "to connect the dots" in Christological historical particulars is a subjective endeavor that requires a great deal of individual deciphering, with reliance especially on the interpretation of perceived symbolism. Fr. Nichols's broad theme-based meditations can provide starting points for further study on more concentrated topics.The most exceptional part of the book is Fr. Nichols's discussion on how Jesus's mysteries exist, simultaneously, in the past, in the present, and in the future. This point is of great significance for both theology and philosophy. For, until the Second Coming, God, not being tied to man's limited experience of time, simultaneously, and... (shrink)

Guided by principles of life history strategy development, this study tested the hypothesis that sexual precocity and violence are influenced by sensitivities to local environmental conditions. Two models of strategy development were compared: The first is based on indirect perception of ecological cues through family disruption and the second is based on both direct and indirect perception of ecological stressors. Results showed a moderate correlation between rates of violence and sexual precocity (r = 0.59). Although a model incorporating direct and (...) indirect effects provided a better fit than one based on family mediation alone, significant improvements were made by linking some ecological factors directly to behavior independently of strategy development. The models support the contention that violence and teenage pregnancy are part of an ecologically determined pattern of strategy development and suggest that while the family unit is critical in affecting behavior, individuals’ direct experiences of the environment are also important.

We tested the hypothesis that choices determined by Type 1 processes are compelling because they are fluent, and for this reason they are less subject to analytic thinking than other answers. A total of 104 participants completed a modified version of Wason's selection task wherein they made decisions about one card at a time using a two-response paradigm. In this paradigm participants gave a fast, intuitive response, rated their feeling of rightness for that response, and were then allowed free time (...) to reconsider their answers. As we predicted, answers consistent with a matching heuristic were made more quickly than other answers, were given higher FOR ratings, and received less subsequent analysis as measured by rethinking time and the probability of changing answers. These data suggest that reasoning biases may be compelling because they are fluently generated; this is turn creates a strong FOR, which acts as a signal that further analysis is not necessary.

This book presents the deterministic view of quantum mechanics developed by Nobel Laureate Gerard 't Hooft. Dissatisfied with the uncomfortable gaps in the way conventional quantum mechanics meshes with the classical world, 't Hooft has revived the old hidden variable ideas, but now in a much more systematic way than usual. In this, quantum mechanics is viewed as a tool rather than a theory. The book presents examples of models that are classical in essence, but can be analysed by (...) the use of quantum techniques, and argues that even the Standard Model, together with gravitational interactions, might be viewed as a quantum mechanical approach to analysing a system that could be classical at its core. He shows how this approach, even though it is based on hidden variables, can be plausibly reconciled with Bell's theorem, and how the usual objections voiced against the idea of 'superdeterminism' can be overcome, at least in principle. This framework elegantly explains - and automatically cures - the problems of the wave function collapse and the measurement problem. Even the existence of an "arrow of time" can perhaps be explained in a more elegant way than usual. As well as reviewing the author's earlier work in the field, the book also contains many new observations and calculations. It provides stimulating reading for all physicists working on the foundations of quantum theory. (shrink)

Superstring theory is an extension of conventional quantum field theory that allows for stringlike and branelike material objects besides pointlike particles. The basic foundations on which the theory is built are amazingly shaky, and, equally amazingly, it seems to be this lack of solid foundations to which the theory owes its strength. We emphasize that such a situation is legitimate only in the development phases of a new doctrine. Eventually, a more solidly founded structure must be sought.Although it is advertised (...) as a “candidate theory of quantum gravity”, we claim that string theory may not be exactly that. Rather, just like quantum field theory itself, it is a general mathematical framework for a class of theories. Its major flaw could be that it still embraces a Copenhagen view on the relation between quantum mechanics and reality, while any “theory of everything”, that is, a theory for the entire cosmos, should do better than that.

Les fractures du temps laissent-elles paraître la durée? Face à l'impossible " omnitemporalité ", l'expérience de la durée. Le geste créateur, l'idée instantanée ou la satisfaction inspirée des artistes interrogent notre lien charnel au monde, qui oscille entre l'abandon au temps morcelé et des synthèses imaginaires. Quand Vénus exauce le désir de Pygmalion, le sculpteur, de voir sa création accéder à la vie, le poète atteste son rêve d'incarnation. Des paradoxes de la physique à la musique répétitive, du cinéma documentaire (...) à la poésie de Michaux, de la synthèse autobiographique de Paul Valéry ou des réflexions de Merleau-Ponty sur l'intersensorialité aux méditations de Heidegger, ces esquisses indiquent les modalités contemporaines de notre présence au monde, dont le cinéma de Wim Wenders ou l'œuvre de Georges Perec portent particulièrement la marque. La sensibilité n'est qu'un autre mot pour dire notre présence au monde. Cet ouvrage approche l'expérience de la durée à travers diverses expressions où s'entrelacent l'attente et l'oubli, le rêve et le récit. Ce souci anime l'action des commissaires d'exposition et des artistes d'aujourd'hui. (shrink)

Methods developed in a previous paper are employed to define an exact correspondence between the states of a deterministic cellular automaton in 1+1 dimensions and those of a bosonic quantum field theory. The result may be used to argue that quantum field theories may be much closer related to deterministic automata than what is usually thought possible.

Conventional particle theories such as the Standard Model have a number of freely adjustable coupling constants and mass parameters, depending on the symmetry algebra of the local gauge group and the representations chosen for the spinor and scalar fields. There seems to be no physical principle to determine these parameters as long as they stay within certain domains dictated by the renormalization group. Here however, reasons are given to demand that, when gravity is coupled to the system, local conformal invariance (...) should be a spontaneously broken exact symmetry. The argument has to do with the requirement that black holes obey a complementarity principle relating ingoing observers to outside observers, or equivalently, initial states to final states. This condition fixes all parameters, including masses and the cosmological constant. We suspect that only examples can be found where these are all of order one in Planck units, but the values depend on the algebra chosen. This paper combines findings reported in two previous preprints (G. ’t Hooft in arXiv:1009.0669 [gr-qc], 2010; arXiv:1011.0061 [gr-qc], 2010) and puts these in a clearer perspective by shifting the emphasis towards the implications for particle models.

Most attempts at obtaining theories that unify quantum mechanics with general relativity require violation of locality and/or causality to some degree. Here, we suggest that these problems actually are very deep and fundamental; hence they may require reconsideration of both quantum mechanics and general relativity at a very fundamental level. An approach called ‘deterministic quantisation’ is sketched.

If philosophers of science advise government on science policy, it will have to be from a descriptive theory of scientific validity taken as hypothetically normative, as in naturalized epistemology. While logical positivism denied any normative import for the practice of science, in the area of "operational definitions" it had an unfortunate influence in psychology and sociology, and one that persists in the accountability movement. Not all philosophy of science issues have implications for the justificatory practice of scientists. For example, both (...) anti-realists and realists condone scientific quarreling about unobserved particles. Many young philosophers of science are now contributing to a sociology of scientific validity which, taken in a hypothetically normative manner, will produce recommendations on science policy.

Balancing Change and Tradition in Global Education Reform is an invaluable resource for policymakers, faculty, students, and anyone interested in how decisions made about the education system ultimately affect the quality of education, educational access, and social justice.

Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet divergences are nearly inevitable. Here, we investigate matter of a form that only displays a finite number of degrees of freedom in compact sections of space-time. In finite domains, one has only exact, analytic solutions. This is achieved by limiting ourselves to straight pieces of string, surrounded by locally flat sections of space-time. (...) Globally, however, the model is not finite, because solutions tend to generate infinite fractals. The model is not (yet) quantized, but could serve as an interesting setting for analytical approaches to classical general relativity, as well as a possible stepping stone for quantum models. Details of its properties are explained, but some problems remain unsolved, such as a complete description of the most violent interactions, which can become quite complex. (shrink)

During the 20 years since the Rwandan genocide a number of younger Rwandan theologians have reflected on the terrible events that ravaged their country in 1994. They have presented PhD theses at different universities in Africa and Europe. Four of these deal explicitly with the 1994 genocide. The basic main question of this review article is how these theologians are looking to reconstruct the broken Rwandan society. This analysis reveals that, while exploring a variety of subjects, each of these theologians (...) is looking for a way in which reconciliation may be achieved in Rwandan society, which has been torn apart by the consequences of the genocide. This article indicates the main issues put forward by these scholars and highlights what they have in common and to what extent they differ. (shrink)

Though we often “fear the worst”, worrying that unexpectedly bad things will happen, there are times when we “hope for the best”, imagining that unexpectedly good things will happen, too. The paper explores how the valence of the current situation influences people's imagining of unexpected future events when participants were instructed to think of “something unexpected”. In Experiment 1, participants (N = 127) were asked to report unexpected events to everyday scenarios under different instructional conditions (e.g., asked for “good” or (...) “bad” unexpected events), and manifested a strong negativity bias in response to non-valenced instructions (i.e., being asked to “think of the unexpected” with no valence given). They mainly reported quite “predictable” unexpected outcomes that were negative; however, a post-test (N = 31) showed that the scenarios used were predominantly positive. In Experiment 2 (N = 257), when participants were instructed to think of “something unexpected and bizarre”, under the same instructional manipulations as Experiment 1, this negativity bias was replicated. In Experiment 3, using a design in which positive/negative materials were matched (verified by a pre-test, N = 60), it was found that when participants (N = 102) were given negative scenarios, they reported more positive events than they do when they are given positive scenarios. Though responding still retained an overwhelming negative bias, this result provided some evidence for a weaker valence-countering strategy; that is, where a negative scenario can lead to positive unexpected events being mentioned, and a positive scenario leads to negative unexpected events being reported. The implications of these results for people's projections of unexpected futures in their everyday lives is discussed. (shrink)

This research empirically investigated the CSR practices of 84 Botswana and Malawi organizations. The findings revealed that the extent and type of CSR practices in these countries did not significantly differ from that proposed by a U. S. model of CSR, nor did they significantly differ between Botswana and Malawi. There were, however, differences between the sampled organizations that clustered into a stakeholder perspective and traditional capitalist model groups. In the latter group, the board of directors, owners, and shareholders were (...) important stakeholders that appeared to be restricting extended stakeholder CSR activities in the Malawi and Botswana organizations. The sampled managers recognized the economic benefits of CSR practices and were not at odds with social objectives. (shrink)

Cultural evolution, producing group‐level adaptations, is more problematic than the cultural evolution of individually confirmable skills, but it probably has occurred. The “conformist transmission,” described by Boyd and Richerson (1985), leads local social units to become homogeneous in anadaptive, as well as adaptive, beliefs. The resulting intragroup homogeneity and inter‐group heterogeneity makes possible a cultural selection of adaptive group ideologies.All archaic urban, division‐of‐labor social organizations had to overcome aspects of human nature produced by biological evolution, due to the predicament of (...) genetic competition among the cooperators. The universal norms found in archaic moral systems are seen as curbs to this human nature, reinforced by beliefs in invisible sanction systems and rewarding and punishing afterlives (as in heaven or reincarnation). Perhaps the ubiquity of lavishly wasteful royal funerals is to be explained as contributing to this function. (shrink)
