Paweł JędrzejkoDepartment of American and Canadian StudiesInstitute of English Cultures and LiteraturesFaculty of PhilologyUniversity of Silesia in KatowicePolandShapes of Time: Science – Literature – Reality(A Reflection upon Sonia Front’s Quantum Consciousness)Abstract: The article offers a reflection upon Sonia Front’s work oriented towards working out adequate intellectual instrumentarium to address quantum fiction: a phenomenon inspired by the philosophical ramifications of crucial developments in physics in the 20th and 21st centuries. Revolving around her recent monograph titled Shapes of Time in British Twenty-First Century Fiction (2015), the argument of the article aims at shedding light on how Sonia Front arrives at the postulate of a certain order countering chaos within a great hermeneutic circle: w wheel in motion, propelling the constant return from the quantum reality to the reality of discurse, a return in which the overwhelming General impacts the ungraspable Detail and the Detail decides about the shape of the General, the great hologram. Front does it in full awareness of the temporariness of such an order, but despite its transience, she decides to formulate an academic statement, to tell a „truth” about the world, time, and human experience: an experience that inescapably becomes her-and our-share. Presented in such a perspective, quantum consciousness, as postulated by Sonia Front, seems to offer a new promise for the research practice of contemporary scholarship.Keywords: quantum mechanics, literary studies, quantum fiction, cultural practice, methodology

Opis:
We have shown that the Schrödinger wave equation can be explained and derived from fundamental postulates that are based on the conservation of probability, significance of measurements at infinity and nature’s tendency of maintaining a system as unbiased as possible. As a reasonable measure for the local randomness, Fisher information is considered. The presented approach provides an axiomatic derivation for the Schrödinger wave equation, avoiding imperfect models borrowed from classical mechanics such as direct application of the energy conservation, statistical mechanics or vibrating string models.

Opis:
According to the author, a perfect example of the theory, which is considered to be removed from the historical context, is the uncertainty principle. For various reasons, this principle became the most famous element of atomic theory, and it usually serves as kick-off for popular lectures in quantum mechanics. This order of presentation can, however, distort an accurate picture of the uncertainty principle and quantum mechanics in general. In this article we try to identify specifically the misunderstandings initiating a course of quantum mechanics contrary to the chronology from the uncertainty principle can lead.

Opis:
Even though the description of the universe in cosmology is known to be given by a smooth 4-dimensional Lorentz manifold for energies below Planck scale, one still can ask about the origins of this phenomenon. In this paper we show that mathematics used for description of quantum systems at micro scale determines smoothness of spacetime at large cosmological scales and indicates the dimension 4 as the only possible dimension for spacetime.

Opis:
One of the most important interpretative problems of quantum mechanics concerns the so called hidden variables. Sometimes it is said that the Bell's theorem falsifies theories of such variables, but in fact, it falsifies only local ones. This paper deals with David Bohm's interpretation of quantum mechanics, which is a kind of nonlocal hidden variable theory. This theory delivers a full deterministic and realistic description of quantum phenomena and predicts the same results as standard quantum mechanics. It is argued that this interpretation is still worth being investigated, because it remains in the full agreement with the mathematical formalism of this theory and it surpasses the standard interpretation as far as simplicity and lack of arbitrary assumptions are concerned.

Opis:
W odpowiedzi Łukasiewiczowi na Opatrzność Boża a przypadek w świecie bronię trzech wniosków. Po pierwsze, stanowisko nazwane przez niego „deizmem epistemicznym” staje przed wyzwaniami ze strony fizyki, których często się nie zauważa. Po drugie, jeśli teiści opowiadający się za argumentem celowościowym opartym na tzw. delikatnym dostrojeniu nie mają racji, to nie ma jej również większość fizyków, która uważa, że delikatne dostrojenie wymaga wyjaśnienia. Po trzecie, nie wszystkie prawa przyrody są warunkowe w takim sensie, jaki przyjmuje Łukasiewicz. Na szczęście rozróżnienie między prawami a nienomologiczną informacją pozwala na rozszerzenie jego modelu działania Boga.
This reply to Łukasiewicz’s “Divine Providence and Chance in the World” argues for three conclusions. First, what he calls “epistemic deism” faces challenges from physics that are not widely recognized. Second, if theists in favor of the fine-tuning design argument are wrong, then so are most physicists, who believe that fine-tuning requires an explanation. Third, not all laws of nature are conditional in the way that Łukasiewicz believes. Fortunately, the distinction between laws and non-nomic information provides a way to expand his model of divine action.

I address the question whether the wave function in quantum theory exists as a real (ontic) quantity or not. For this purpose, I discuss the essentials of the quantum formalism and emphasize the central role of the superposition principle. I then explain the measurement problem and discuss the process of decoherence. Finally, I address the special features that the quantization of gravity brings into the game. From all of this I conclude that the wave function really exists, that is, it is a real (ontic) feature of Nature.

Opis:
The history of quantum mechanics is divided into two periods which are labeled as the first and the second quantum revolutions. During the first of these periods mathematical formalism of quantum theory was formulated and interpreted, during the second – new quantum technologies were developed. It turns out that conceptual revolution of the first period enabled technological revolution of the second. In this article it is argued, that Irish physicist, John S. Bell, played an important role in the process of triggering the second quantum revolution. His work on quantum entanglement of the EPR particles made possible elaborating some new methods and theoretical approaches clarifying the quantum description of single objects. These methods and approaches became the core of new scientific domains which are hybrids of quantum mechanics and some classical sciences. The quantum cryptography and the quantum computation are examples of such domains and in the paper special attention is paid to them. It is showed that theoretical analyses of John S. Bell provide a conceptual background for these disciplines and this is why it’s not improper to call this physicist – as Alain Aspect did – a prophet of the second quantum revolution.

Opis:
The article entitled “The strange world of quanta” tries to explain, in a very general and selective way, the physics theory known as the quantum mechanics. In opposition to the classical modern theories – the classical mechanics and the mechanism – the quantum mechanics has been characterized as the new revolutionary theory which changed the scientific method and the way the reality was perceived in the XXth century. The title of this article is inspired by the apparent divergence between the everyday world and the world described by the quantum mechanics. The quantum physics is a theory which has been confirmed empirically multiple times and which greatly influenced the technological development in the XXth century. It is also hoped that it will help the humanity in the future. However, as the theory which describes the micro-scale world it stands in opposition to another influential theory of the XXth century – the general theory of relativity – which describes the macro-scale world. The problem is that these two theories can not be both fundamental and true at the same time, as they describe the two aspects of the same world. This incoherence of the laws of the universe is especially disturbing when we take into account the fact that according to the Big Bang theory the universe emerged from the micro-world. Therefore, the science community awaits the emergence of the so-called “theory of everything” which could unify both theories and explain the processes taking place in the micro- and macro-scale equally well.

Opis:
The dichotomic physical quantities, also called propositions, can be naturally associated to maps of the set of states into the real interval [0,1]. We show that the structure of effect algebra associated to such maps can be represented by quasiring structures, which are a generalization of Boolean rings, in such a way that the ring operation of addition can be non-associative and the ring multiplication non-distributive with respect to addition. By some natural assumption on the effect algebra, the associativity of the ring addition implies the distributivity of the lattice structure corresponding to the effect algebra. This can be interpreted as another characterization of the classicality of the logical systems of propositions, independent of the characterizations by Bell-like inequalities.

Opis:
The aim of this paper is to present the views of one of prominent Polish chemists, namely Bohdan Szyszkowski. Presented views are concerning the relation of the concepts of aether, continuity and causality in the context of revolution in physics that took place at the turn of 19th and 20th centuries. The issues particularly concern his thoughts related to the old quantum theory and special relativity. In particular, this article presents the role of these concepts in the foundations of physics and – in a more general aspect – in the recognized fields of knowledge. The nature of Szyszkowski’s analysis allows him to be considered a very interesting thinker in the area that today is called the philosophy of physics or, perhaps more accurately, the philosophy in science. An important observation made by Szyszkowski is emphasized that mathematical structures cannot have physical properties. Attention was also paid to the Polish intellectual community, which was formed in Kiev before 1919.

This article is drafted on the basis of three complementary essays by Professor Jerzy Janik. The author takes a look at selected issues in the field of quantum mechanics – especially the problem of quantum superposition and supersymmetry – from perspective of great philosophical systems. The author draws attention to the fact that some of these issues reflect old philosophical problems (e.g., empiricism vs rationalism), and – in some cases – philosophical perspective may save interpretations of quantum mechanics from paradoxes.

Schrödinger's cat
Opis:
The Schrödinger's Cat paradox was proposed in 1935 by Edwin Schrodinger, one of the founders of quantum mechanics, as an attempt to visualize the macroscopic realization of a quantum superposition state. A cat is placed in a sealed box together with a vial of poison. A two-state particle (e.g. an electron) is sent into a detector in the box resulting either in a broken or an intact vial and a dead or live cat, respectively. The main problem consists in whether the superposition state of a microscopic particle can be transferred upon the macroscopic cat, that is, whether the cat can exist in a superposition state, being simultaneously dead and alive. Since the standard Copenhagen interpretation is unable to assign any reality to the quantum superposition state, the paradox finds no resolution within the regime of this interpretation. Von Neumann's insistence on the uniform treatment of both microscopic (quantum) and macroscopic (classical) objects according to the laws of quantum mechanics provides a more consistent framework for the resolution of the paradox. In particular, the discovery of the phenomenon of decoherence, whereby the disappearance of the quantum interferences at the macro level is accounted for, suggests the onset of an extremely efficient interference relaxation process (10-23 s) upon the interaction of the two state particle with the detector. As a result, Schrodinger's cat can exist macroscopically either as dead or alive and never as a combination of both. Decoherence not only aids the resolution of the Schrodinger's Cat paradox but also sheds light upon the mechanisms by which the macro-world emerges from the microscopic quantum realm.

Opis:
W artykule przedstawiono w prosty sposób wyprowadzenie nierówności Bella, odgrywającej ważną rolę w próbach zrozumienia natury cząstek elementarnych. Nierówność ta, wyprowadzona przy pewnych „rozsądnych” założeniach realizmu i lokalności, nie jest spełniona w mikroświecie. Oznacza to więc, że owe założenia nie muszą należeć do paradygmatu poznania mikroświata. Jego „dziwność” stawia wysokie wymagania naszej wyobraźni opartej na intuicji wywodzącej się ze świata makroskopowego.
The paper contains a simple introduction to the Bell’s inequality which is important in understanding the nature of elementary particles. The inequality was derived under “reasonable” assumption of realism and locality and is not satisfied in the quantum world of particles. It means that the above assumption does not necessarily belong to the quantum world paradigm.
