Résumé Et toi, quel est ton genre? Les Betty, intellectuelles précaires, partageant un désir militant, critiques tant vis-à-vis des groupes féministes historiques, que des pratiques politiques au sein du mouvement des mouvements, nous racontent leur création d’un espace, le "sexishock" au cœur même d’un centre social à Bologne.

The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed (...) back into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me. (shrink)

Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. They are difficult because the fundamental dynamical laws of physics do not privilege an arrow of time, and the quantum-mechanical wave function describes a high-dimensional reality that is radically different from our ordinary experiences. -/- In this paper, I characterize and elaborate on the ``Wentaculus” theory, a new approach to time’s (...) arrow in a quantum universe that offers a unified solution to both problems. Central to the Wentaculus are (i) Density Matrix Realism, the idea that the quantum state of the universe is objective but can be impure, and (ii) the Initial Projection Hypothesis, a new law of nature that selects a unique initial quantum state. On the Wentaculus, the quantum state of the universe is sufficiently simple to be a law, and the arrow of time can be traced back to an exact boundary condition. It removes the intrinsic vagueness of the Past Hypothesis, eliminates the Statistical Postulate, provides a higher degree of theoretical unity, and contains a natural realization of “strong determinism." I end by responding to four recent objections. In a companion paper, I elaborate on Density Matrix Realism. (shrink)

Realism about quantum theory naturally leads to realism about the quantum state of the universe. It leaves open whether it is a pure state represented by a wave function, or an impure one represented by a density matrix. I characterize and elaborate on Density Matrix Realism, the thesis that the universal quantum state is objective but can be impure. To clarify the thesis, I compare it with Wave Function Realism, explain the conditions under which they are empirically equivalent, (...) consider two generalizations of Density Matrix Realism, and answer some frequently asked questions. I end by highlighting an implication for scientific realism. (shrink)

We provide a logical matrix semantics and a Gentzen-style sequent calculus for the first-degree entailments valid in W. T. Parry’s logic of Analytic Implication. We achieve the former by introducing a logical matrix closely related to that inducing paracomplete weak Kleene logic, and the latter by presenting a calculus where the initial sequents and the left and right rules for negation are subject to linguistic constraints.

In this chapter, the author says that the standard view of brain‐in‐a‐vat scenario is endorsed by the people who created The Matrix. The author argues that the hypothesis that he is envatted is not a skeptical hypothesis, but a metaphysical hypothesis. That is, it is a hypothesis about the underlying nature of reality. According to the author, the Matrix Hypothesis is equivalent to a version of the following three‐part Metaphysical Hypothesis. First, physical processes are fundamentally computational. Second, our (...) cognitive systems are separate from physical processes, but interact with these processes. Third, physical reality was created by beings outside physical space‐time. The Metaphysical Hypothesis combines the Creation Hypothesis, the Computational Hypothesis, and the Mind‐Body Hypothesis. It also adds a more specific claim: the computational processes underlying physical space‐time were designed by the creators as a computer simulation of a world. (shrink)

Intrigued by Robinson and Southgate's 2010 work on “entering a semiotic matrix,” we expand their model to include the juxtaposition of all signs, symbols, and mental categories, and to explore the underpinnings of creativity in science, religion, and art. We rely on an interdisciplinary review of human sentience in archaeology, evolutionary biology, the cognitive science of religion, and literature, and speculate on the development of sentience in response to strong selection pressure on the hominin evolutionary line, leaving us the (...) “lone survivors” of complex, multiple lines of physical and cultural evolution. What we call Matrix Thinking—the creative driver of human sentience—has important cognitive and intellectual features, but also equally important characteristics traced to our intense sociability and use of emotionality in vetting rational models. Scientist, theologian, and artist create new cultural knowledge within a social context even if alone. They are rewarded by emotional validation from group members, and guided by the ever present question, “Does it feel right?”. (shrink)

Using matrix iterations of ccc posets, we prove the consistency with ZFC of some cases where the cardinals on the right hand side of Cichon’s diagram take two or three arbitrary values (two regular values, the third one with uncountable cofinality). Also, mixing this with the techniques in J Symb Log 56(3):795–810, 1991, we can prove that it is consistent with ZFC to assign, at the same time, several arbitrary regular values on the left hand side of Cichon’s diagram.

The present article shows that there are consistent and decidable manyvalued systems of propositional logic which satisfy two or all the three criteria for non-trivial inconsistent theories by da Costa . The weaker one of these paraconsistent system is also able to avoid a series of paradoxes which come up when classical logic is applied to empirical sciences. These paraconsistent systems are based on a 6-valued system of propositional logic for avoiding difficulties in several domains of empirical science ).

Drawing on 75 semi-structured qualitative interviews with Arab, South Asian, and Black Muslim women social justice activists, ages 18–30 years, organizing in the United States and the United Kingdom, I theorize their experiences as the basis of the matrix of gendered Islamophobia. Building upon Jasmine Zine’s concept of gendered Islamophobia, I synthesize this concept with Patricia Hill Collins’s theory of the matrix of domination to give a more in-depth and nuanced structure of how gendered Islamophobia operates and is (...) resisted by Muslim women activists. This article identifies the overlapping configurations of power that affect Muslim women’s lives through structural, disciplinary, hegemonic, and interpersonal domains, countering reductionist accounts of Islamophobia as a universalized, unvariegated social force impacting all Muslims in similar ways. Instead, the matrix of gendered Islamophobia locates Islamophobia within shifting axes of oppression that are simultaneously structured along the lines of gender, race, class, sexuality, and citizenship. The findings of this research reveal a dialectical relationship between Muslim women’s oppression and simultaneous contestation of gendered Islamophobia via their collective remaking of alternative ideas, politics, discourses, and organizing practices.

In this revolutionary work, the author sets the stage for the science of the 21st Century, pursuing an unprecedented synthesis of fields previously considered unrelated. Beginning with simple classical concepts, he ends with a complex multidisciplinary theory requiring a high level of abstraction. The work progresses across the sciences in several multidisciplinary directions: Mathematical logic, fundamental physics, computer science and the theory of intelligence. Extraordinarily enough, the author breaks new ground in all these fields. In the field of fundamental physics (...) the author reaches the revolutionary conclusion that physics can be viewed and studied as logic in a fundamental sense, as compared with Einstein's view of physics as space-time geometry. This opens new, exciting prospects for the study of fundamental interactions. A formulation of logic in terms of matrix operators and logic vector spaces allows the author to tackle for the first time the intractable problem of cognition in a scientific manner. In the same way as the findings of Heisenberg and Dirac in the 1930s provided a conceptual and mathematical foundation for quantum physics, matrix operator logic supports an important breakthrough in the study of the physics of the mind, which is interpreted as a fractal of quantum mechanics. Introducing a concept of logic quantum numbers, the author concludes that the problem of logic and the intelligence code in general can be effectively formulated as eigenvalue problems similar to those of theoretical physics. With this important leap forward in the study of the mechanism of mind, the author concludes that the latter cannot be fully understood either within classical or quantum notions. A higher-order covariant theory is required to accommodate the fundamental effect of high-level intelligence. The landmark results obtained by the author will have implications and repercussions for the very foundations of science as a whole. Moreover, Stern's Matrix Logic is suitable for a broad spectrum of practical applications in contemporary technologies. (shrink)

The paper offers a matrix-based logic (relevant matrix quantum physics) for propositions which seems suitable as an underlying logic for empirical sciences and especially for quantum physics. This logic is motivated by two criteria which serve to clean derivations of classical logic from superfluous redundancies and uninformative complexities. It distinguishes those valid derivations (inferences) of classical logic which contain superfluous redundancies and complexities and are in this sense from those which are or in the sense of allowing only (...) the most informative consequences in the derivations. The latter derivations are strictly valid in RMQ, whereas the former are only materially valid. RMQ is a decidable matrix calculus which possesses a semantics and has the finite model property. It is shown in the paper how RMQ by its strictly valid derivations can avoid the difficulties with commensurability, distributivity, and Bell's inequalities when it is applied to quantum physics.

We propose a rational method for addressing an important question—who deserves to be an author of a scientific article? We review various contentious issues associated with this question and recommend that the scientific community should view authorship in terms of contributions and responsibilities, rather than credits. We propose a new paradigm that conceptually divides a scientific article into four basic elements: ideas, work, writing, and stewardship. We employ these four fundamental elements to modify the well-known International Committee of Medical Journal (...) Editors (ICMJE) authorship guidelines. The modified ICMJE guidelines are then used as the basis to develop an approach to quantify individual contributions and responsibilities in multi-author articles. The outcome of the approach is an authorship matrix, which can be used to answer several nagging questions related to authorship. (shrink)

Husserl’s commitment to reality is marked by the urgency to return, or rather to a repeated return each time the objective is achieved . He explains this explicitly in The Crisis of European Sciences and Transcendental Phenomenology, taking his cue from Descartes’ Meditations . Reduction, which is the exact name for re- turn, means change of attitude, abandonment of the natural position as naive . Jan Patočka notes in this regard, that today people who have experienced modern sci- ence no (...) longer simply live in the naive natural world . The naive natural world is in- terpreted under species of the mathematical model . So, the gap between meaning as an expectation of experience and meaning within the framework of the model is increasingly evident . If intentionality, according to Husserl and disciples, includ- ing Heidegger, cannot be other than the idea itself, then it is just a something for something . It’s like giving voice to one thing and not another . Commitment to life (Husserl’s Lebenswelt) requires a return to corporeality, as Patočka adds, following Maine de Biran’s accurate insight, that is, of something immediately given, prior to any perceptual experience . The term “matrix” in the title brings to mind the eponymous 1999 film based on the philosophical metaphor of Plato’s cave in the fashion of the digital age . The protagonist, Neo, finds himself living for a long time in the lack of support of reality, precisely because of distrust: something is wrong, and this can only be felt . However, how can the hacker mentality help you under- stand that perhaps it is but a game? (shrink)

This book explores Gilles Deleuze's contribution to film theory. According to Deleuze, we have come to live in a universe that could be described as metacinematic. His conception of images implies a new kind of camera consciousness, one that determines our perceptions and sense of selves: aspects of our subjectivities are formed in, for instance, action-images, affection-images and time-images. We live in a matrix of visual culture that is always moving and changing. Each image is always connected to an (...) assemblage of affects and forces. This book presents a model, as well as many concrete examples, of how to work with Deleuze in film theory. It asks questions about the universe as metacinema, subjectivity, violence, feminism, monstrosity, and music. Among the contemporary films it discusses within a Deleuzian framework are Strange Days, Fight Club, and Dancer in the Dark. (shrink)

This article seeks to re-evaluate the importance of the political in the thinking of Maurice Merleau-Ponty. The article first shows that Sartre’s description of Merleau-Ponty’s intellectual trajectory as one of increasing political apathy from the 1950s onwards is inaccurate. The article then demonstrates that throughout the post-war period, including in his project for a new ontology, Merleau-Ponty believed that a revised version of Marxism would provide the methodological framework within which philosophical work could address the political challenges of the present. (...) This revised Marxism was to be a direct alternative to the reifying uses of Marx’s thinking. It would rely upon the latter’s self-reflexive historicism, which meant its very failures showed how philosophy might transform itself in connection with its own time. Cet article tente souligner la place du politique dans la pensée de Maurice Merleau-Ponty. On contestera d’abord la description faite par Sartre de sa trajectoire intellectuelle, selon laquelle il aurait fait preuve d’une apathie croissante, à partir des années cinquante, vis-à-vis des questions politiques. On montrera ensuite que durant toute la période d’après-guerre, jusque dans les recherches ontologiques ultimes, Merleau-Ponty a pensé qu’un usage renouvelé du marxisme permettrait au travail philosophique de répondre aux défis politiques du présent. Une telle révision du marxisme représentait une alternative directe aux usages réifiant de la pensée de Marx. Cette révision serait rendue possible par la réflexivité historiciste de cette pensée, qui fait que, dans ses erreurs mêmes, celle-ci révèle la capacité de la philosophie à se transformer au contact de son temps.

In this pioneering work, the author develops a fundamental formulation of logic in terms of theory of matrices and vector spaces. The discovery of matrix logic represents a landmark in the further formalization of logic. For the first time the power of direct mathematical computation is applied to the whole set of logic operations, allowing the derivation of both the classical and modal logics from the same formal base. The new formalism allows the author to enlarge the alphabet of (...) the truth-values with negative logic antivalues and to link matrix logic descriptions with the Dirac formulation of quantum theory - a result having fundamental implications and repercussions for science as a whole. As a unified language which permits a logical examination of the underlying phenomena of quantum field theory and vice versa, matrix logic opens new avenues for the study of fundamental interactions and gives rise to a revolutionary conclusion that physics as such can be viewed and studied as a logic in the fundamental sense. Finally, modelling itself on exact sciences, matrix logic does not refute the classical logic but instead incorporates it as a special deterministic limit. The book requires multidisciplinary knowledge and will be of interest to physicists, mathematicians, computer scientists and engineers. (shrink)

Two experiments used eyetracking during reading to examine the processing of the matrix verb following object and subject relative clauses. The experiments show that the processing of the matrix verb following an object relative is indeed slowed compared to the processing of the same verb following a subject relative. However, this difficulty is entirely eliminated if additional material intervenes between the object gap and the matrix verb. An explanation in terms of spillover processing is ruled out, suggesting (...) that it is the gap-matrix verb sequence that is itself responsible for the difficulty. We consider two accounts of this difficulty, one emphasizing the potential difficulty of rapidly switching between the sentential subject's thematic or syntactic role in the embedded clause and its role in the matrix clause, and one emphasizing the potential difficulty of performing two demanding memory retrievals in rapid succession. The present experiments also closely replicate the previous findings from eyetracking that the noun phrase and the verb within an object relative are both loci of processing difficulty, but that the former induces substantially greater difficulty.

The question "Where do we come from?" has fascinated philosophers, scientists, and artists for generations. This book reorients the question of the matrix as a place where everything comes from (_chora_, womb, incubator) by recasting it in terms of acts of "matrixial/maternal hospitality" producing space and matter of and for the other. Irina Aristarkhova theorizes such hospitality with the potential to go beyond tolerance in understanding self/other relations. Building on and critically evaluating a wide range of historical and contemporary (...) scholarship, she applies this theoretical framework to the science, technology, and art of ectogenesis (artificial womb, neonatal incubators, and other types of generation outside of the maternal body) and proves the question "Can the machine nurse?" is critical when approaching and understanding the functional capacities and failures of incubating technologies, such as artificial placenta. Aristarkhova concludes with the science and art of male pregnancy, positioning the condition as a question of the hospitable man and newly defined fatherhood and its challenge to the conception of masculinity as unable to welcome the other.

I will try to explain in the context of the Matrix and philosophy what the truth is and whether there is the free will or not. Everyone wants to know the truth, but no one clearly explains what it is. The matrix is the desert of the truth and human mind remains therein thirsty. Can we know that we are alive or dead, that is to say, what is the difference between reality and imagination? Never can this problem (...) only be solved by our minds? So long as we try to arrive at necessity, we absolutely remain in possibility. (shrink)

We clarify different definitions of the density matrix by proposing the use of different names, the full density matrix for a single-closed quantum system, the compressed density matrix for the averaged single molecule state from an ensemble of molecules, and the reduced density matrix for a part of an entangled quantum system, respectively. We show that ensembles with the same compressed density matrix can be physically distinguished by observing fluctuations of various observables. This is in (...) contrast to a general belief that ensembles with the same compressed density matrix are identical. Explicit expression for the fluctuation of an observable in a specified ensemble is given. We have discussed the nature of nuclear magnetic resonance quantum computing. We show that the conclusion that there is no quantum entanglement in the current nuclear magnetic resonance quantum computing experiment is based on the unjustified belief that ensembles having the same compressed density matrix are identical physically. Related issues in quantum communication are also discussed. (shrink)

Longitudinal diagnostic classification models (DCMs) with hierarchical attributes can characterize learning trajectories in terms of the transition between attribute profiles for formative assessment. A longitudinal DCM for hierarchical attributes was proposed by imposing model constraints on the transition DCM. To facilitate the applications of longitudinal DCMs, this paper explored the critical topic of the Q-matrix design with a simulation study. The results suggest that including the transpose of the R-matrix in the Q-matrix improved the classification accuracy; ten-item (...) tests measuring three linear attributes across three time points provided satisfactory classification accuracy for low-stakes assessment. Educational implications and future directions were discussed. (shrink)

_The Matrix_ Written and directed by Andy and Larry Wachowski Village Roadshow Pictures, 1999.

'The Matrix Project' comprises two contexts, namely photographic work of architect Thierry Lagrange and the self-reflective trajectory that he developed during his doctorate at KULeuven. Lagrange's practice-based research developed to an autonomous artistic project, in which he studied the signification and nature of observation within a creative process. Through his multifaceted practice as an architect, photographer and researcher, Lagrange developed 'The Matrix Method'; a method that stimulates creativity within different contexts and can be implemented for example in art (...) education. For the Matrix Project, 25 years' worth of photographs was entered into a context of research and presents a new perspective on different ways of seeing in our present visual culture. (shrink)

Motivated by a question of W. Rautenberg, we prove that any matrix that is term-equivalent to the well-known nonfinitely based matrix of A. Wroski is itself also nonfinitely based.

Character structures underlie everyone’s personality. When rigidly defended, they limit us; yet as they become more flexible, they can reveal sources of animation, renewal and authenticity. _The Matrix and Meaning of Character_ guides the reader into an awareness of the archetypal depths that underlie character structures, presenting an original developmental model in which current analytic theories are synthesised. The authors examine nine character structures, animating them with fairy tales, mythic images and case material, creating a bridge between the traditional (...) language of psychopathology and the universal realm of image and symbol. This book will appeal to all analytical psychologists, psychoanalysts and psychotherapists who want to strengthen their clinical expertise. It will help clinicians to extend their clinical insights beyond a strictly behavioural, medical or cognitive approach, revealing the potential of the human spirit. (shrink)

The matrix notation of paper I is extended to include first-rank spinors expressed as two-component spin-vectors. Well-known two-component and four-component spinor equations are expressed in this notation. In addition, it is shown how other covariant wave equations can easily be invented. A certain nonlinear equation is found to have only positive-energy solutions for particles and antiparticles.

In this multidisciplinary book, mathematician Matthew He provides integrative perspectives of algebraic biology, cognitive informatics, and poetic expressions of the human mind. Using classical Pythagorean Theorem and contemporary Category Theory, the proposed matrix models of the human mind connect three domains of the physical space of objective matters, mental space of subjective meanings, and emotional space of bijective modes; draws the connections between neural sparks and idea points, between synapses and idea lines, and between action potentials and frequency curves.

The matrix‐degrading metalloproteinases are an intriguing family of enzymes that have evolved to digest specific extracellular matrix components. The expression of these enzymes is very highly regulated and can be controlled transcriptionally by a number of growth factors, tumor promoters, oncogenes, and hormones. It is suggested that the coordinated regulation of matrix metalloproteinases and their inhibitors by these agents modify the integrity of the extracellular matrix. These modifications may, at least in part, be responsible for mediating (...) the effects of these factors on complex physiological processes. (shrink)

If the density matrix is treated as an objective description of individual systems, it may become possible to attribute the same objective significance to statistical mechanical properties, such as entropy or temperature, as to properties such as mass or energy. It is shown that the de Broglie--Bohm interpretation of quantum theory can be consistently applied to density matrices as a description of individual systems. The resultant trajectories are examined for the case of the delayed choice interferometer, for which Bell (...) [Int. J. Quantum chem. 155--159, (1980)] appears to suggest that such an interpretation is not possible. Bell’s argument is shown to be based upon a different understanding of the density matrix to that proposed here. (shrink)

The aim of this paper is to show that the operations of forming direct products and submatrices suffice to construct exhaustive semantics for all structural strengthenings of the consequence determined by a given class of logical matrices.

We present a matrix model for the study of the population dynamics of brown trout Salmo trutta L., introduced in the '60s in the virgin aquatic ecosystems of the Kerguelen Islands. This species clearly acclimatized very well: a portion of the population became migratory and spent a part of its life cycle in the sea, which allowed the rapid colonization of two rivers close to the stream of origin in the same bay (Baie Norvégienne).These migratory trout can become a (...) smolt at 2, 3, or 4 years of age. The model takes into account age and smolt age structures and in a first step considers the fish from the Baie Norvégienne as belonging to a single population. The transition matrix looks like a 32 × 32 Leslie matrix in which some survival rates are not on the subdiagonal. They represent survival after the first sea migration and are particularly important for the dynamics of the whole population. (shrink)
