    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.

    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:
    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.

    Opis:
    The current 50th issue of Philosophical Problems in Science (Zagadnienia Filozoficzne w Nauce) summarizes the efforts of both philosophers and scientists to understand how a broader philosophical context sets the stage for the development of scientific research, with physics playing a leading role. In particular, the paper reviews the content of the last twenty-five issues of the journal with an emphasis on the philosophical problems that arise in the practice of physics. The overview reveals that these problems reflect the main conceptual division in physics between the treatment of the micro-world described by quantum mechanics and the macro-world governed by the general theory of relativity. Both of these theories, taken separately, generate a host of philosophical concerns such as their proper interpretation (Bell’s Theorem and its consequences) or the meaning and the eventual validity of the notions of space and time. Other philosophical problems in physics, such as chaos and determinism, are also considered. The authors are well aware that the formulation of the future theory of quantum gravity will be a demanding task requiring profound philosophical reflection.

    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:
    Unlike in the classical regime, the measurement performed on a quantum system perturbs the state of the system and its properties remain unknown between measurements. Several early interpretations of quantum mechanics suggested that the reduction of the wave vector that occurs in a measurement is effected by a conscious act of an observer. For example, London and Bauer fostered the conviction that it is the act of observation that decides on the fate of the Schrodinger cat. Later developments of quantum mechanical formalism, e.g., decoherence, indicated that there was no need to causally link the mental states of an observer with the purely physical process of a quantum measurement. In particular, the novel quantum models of human brain put forward by Roger Penrose suggest that it is the reduction of the wave vector that causes conscious act of the observer. Although this reversal does not clarify the specifics of the quantum measurement process directly, it illustrates the principle of methodological naturalism whereby externally introduced heuristic postulates are replaced by well justified scientific explanations.

    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 double slit experiment is a relatively simple physical test that can be useful for demonstrating the corpuscular-wave dualism of light and matter, which is the supreme mystery of the whole quantum physics. A particular riddle here is especially the mechanism responsible for the formation of a interference pattern in a situation when single quantum objects pass through the experimental setup. In the article the main idea of the experiment is discussed and two possible explanations of its results are briefly shortly presented: the view of the Copenhagen school and the de Broglie-Bohm’s pilot wave theory.

    Opis:
    The 1935 thought experiment of Einstein, Podolsky and Rosen is one of the most important episodes in the history of the dispute about the correct interpretation of quantum mechanics. The present paper deals with the origin of the EPR paper and discusses some other thought experiments that preceded the formulation of the Einstein-Podolsky-Rosen argument. Special attention is paid to the evolution of a simply photon-box experiment, which was devised by Einstein in 1930 and then modified by him several times before 1935. It is argued that the scheme of the original EPR argument is in fact contained in these few seminal experiments.

    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:
    The paper can be regarded as a short and informal introduction to noncommutative calculi of probability. The standard theory of probability is reformulated in the algebraic language. In this form it is readily generalized to that its version which is virtually present in quantum mechanics, and then generalized to the so-called free theory of probability. Noncommutative theory of probability is a pair (M, φ) where M is a von Neumann algebra, and φ a normal state on M which plays the role of a noncommutative probability measure. In the standard (commutative) theory of probability, there is, in principle, one mathematically interesting probability measure, namely the Lebesgue measure, whereas in the noncommutative theories there are many nonequivalent probability measures. Philosophical implications of this fact are briefly discussed.

    Opis:
    Andrzej Dragan’s book Quantechism or a cage for people is a great popular science book to start a fascinating adventure with the theory of relativity and quantum mechanics. It is written in an easy language, does not require from the reader a deep knowledge of contemporary physical issues, while describing, illustrating and explaining them very well. Instead, it requires broader historical knowledge and at least basic philosophical knowledge for verification, helping to bring out what is most valuable in the book. Unfortunately, the book, while popularizing science, also makes a terrible mess and does a lot of damage to the deeper understanding of physics, its history, and the meaning and function of philosophy and religion. And so it can become an attractive and appealing, but nevertheless a trap-cage for thinking people.

    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.
