AbstractQuantum mechanics for describing the behavior of microscopic entities and thermodynamics for describing macroscopic systems exhibit separate time concepts. Whereas many theories of modern physics interpret processes as reversible, in thermodynamics, an expression for irreversibility and the so-called time arrow has been developed: the increase of entropy. The divergence between complete reversibility on the one hand and irreversibility on the other is called the paradox of time. Since more than hundred years many efforts have been devoted to unify the time concepts. So far, the efforts were not successful. In this paper a solution is proposed on the basis of matter-energy equivalence with an energetic distinction between matter and mass. By refraining from interpretations predominant in modern theoretical physics, the first and second laws of thermodynamics can be extended to fundamental laws of nature, which are also valid at quantum level.

AbstractOver the last two centuries, thermodynamics has contributed significantly to technical and industrial progress. According to phenomenological thermodynamics developed by Rudolf Clausius and Josiah Willard Gibbs, properties such as volume or interface represent energetic qualities of a real body. In the present work, the energy concepts of thermodynamics and special relativity are connected with each other. The plausibility of complete mass-energy equivalence is evaluated within the thermodynamic context. Einstein’s interpretation of the well-known equation E = mc2 as complete mass-energy equivalence results as a special case for idealized moving point masses – according to the assumptions of the theory of special relativity. It is shown that mass is one energy-equivalent property of matter, but not the only one, because complete mass-energy equivalence contradicts the principle of conservation of energy. Thermodynamics suggests matter-energy equivalence. In accordance with the two main laws of thermodynamics and corresponding with experimental facts, it forms the basis of an in-depth understanding of nature and provides impetus for the research in quantum physics, thermodynamics and astrophysics.

The phenomenon of quantum erasure exposed a remarkable ambiguity in the interpretation of quantum entanglement. On the one hand, the data is compatible with the possibility of arrow-of-time violations. On the other hand, it is also possible that temporal non-locality is an artifact of post-selection. Twenty years later, this problem can be solved with a quantum monogamy experiment, in which four entangled quanta are measured in a delayed-choice arrangement. If Bell violations can be recovered from a “monogamous” quantum system, then the arrow of time is obeyed at the quantum level.

This paper examines the intersecting of the themes of temporality and truth in Deleuze's philosophy. For the ancients, truth was something eternal: what was true was true in all times and in all places. Temporality (coming to be and passing away) was the realm of the mutable, not the eternal. In the seventeenth century, change began to be seen in a positive light (progress, evolution, and so on), but this change was seen to be possible only because of the immutable laws of nature that govern change. It was not until philosophers such as Bergson, James, Whitehead – and then Deleuze – that time began to be taken seriously on its own account. On the one hand, in Deleuze, time, freed from its subordination to movement, now becomes autonomous: it is the pure form of change (continuous variation) that lies at the basis of Deleuze's metaphysics in Difference and Repetition (and is explored more thematically in The Time-Image). As a result, on the other hand, the false, freed from its subordination to the form of the true, assumes a power of its own (the power of the false), which in turn implies a new ‘analytic of the concept’ that Deleuze develops in What Is Philosophy?

The paper makes an attempt to resolve two conceptual mingling: (a) the mingling of the two interpretations of the concept of orderedness applied in statistical thermodynamics and in symmetrology, and (b) the mingling of two interpretations of evolution applied in global and local processes. In conclusion, it formulates a new interpretation on the relation of the emergence of new material qualities in selforganizing processes on the one hand, and the evolution of the universe, on the other. The process of evolution is a sequence of emergence of new material qualities by self-organization processes, which happen in negligible small segments of the universe. Although thermodynamics looks at the universe as a closed (isolated) system, this holds for its outside boundaries only, while the universe has many subsystems inside, which are not isolated (closed), since they are in a permanent exchange of matter, energy, etc. with their environment (with the rest of the universe) through their open boundaries. Any ";;emergence";; takes place, i.e., all new qualities come into being just in these small open segments of the universe. The conditions to apply the second law of thermodynamics are not present here. Therefore, global evolution of the universe is the consequence of local symmetry decreases, local decreases of orderedness, and possible local decreases of entropy.

Although Pierre Duhem is well known for his conventionalist outlook and, in particular, for his critique of crucial experiments outlined in his thesis on the empirical indeterminacy of theory, he also contributed to the scholarship on the psychological profiles of scientists by revising Pascal’s famous distinction between the subtle mind and the geometric mind (esprits fins and esprits géométriques). For Duhem, the ideal scientist is the one who combines the defining qualities of both types of intellect. As a physicist, Duhem made important theoretical contributions to the field of thermodynamics as well as to the then-nascent physical chemistry. Due to his rejection of atomism and his unrelenting critique of Maxwell’s electrodynamics, however, in his later years, Duhem’s work was surpassed and abandoned by the dominant tendencies of physics of the time. In this essay, I will discuss whether Duhem himself can be understood through the lens of his own account of the scientist’s psychological profile. More specifically, I examine whether the subtle mind – to which he seems to assign greater cognitive value – in fact plays a key role in Duhem’s critique of the English School (école anglaise), or if his preference for the axiomatic structure of theoretical physics shows a greater affinity with the geometric mind.

Abstract A metaphysical fact is a fact, clearly recognizable in the course of time, for which there is no scientific explanation, that is, no legal explanation or explanation deduced in the manner recommended by modern science. I contend that life’s emergence and human thought’s emergence are metaphysical facts in this sense. These emergences are not to be explained by Darwinian principles which themselves do not seem adequate to explain genetic evolutionism. But modern cosmology has given us leave to reflect on cosmic evolution in a manner which gives sense to overall finality. There is an anthropic principle which has two forms: in the weak form, it can help science discover new legal explanations; in the strong form, it offers a teleological explanation of the laws of nature. As F. Dyson noted, we have two styles of explanation: the one is scientific; the other is metascientific (or metaphysical). We have no reason to reject teleological explanations about ontological questions.

Quantum Mechanics is one of the most successful theories of nature. It accounts for all known properties of matter and light, and it does so with an unprecedented level of accuracy. On top of this, it generated many new technologies that now are part of daily life. In many ways, it can be said that we live in a quantum world. Yet, quantum theory is subject to an intense debate about its meaning as a theory of nature, which started from the very beginning and has never ended. The essence was captured by Schrödinger with the cat paradox: why do cats behave classically instead of being quantum like the one imagined by Schrödinger? Answering this question digs deep into the foundation of quantum mechanics. A possible answer is Dynamical Collapse Theories. The fundamental assumption is that the Schrödinger equation, which is supposed to govern all quantum phenomena (at the non-relativistic level) is only approximately correct. It is an approximation of a nonlinear and stochastic dynamics, according to which the wave functions of microscopic objects can be in a superposition of different states because the nonlinear effects are negligible, while those of macroscopic objects are always very well localized in space because the nonlinear effects dominate for increasingly massive systems. Then, microscopic systems behave quantum mechanically, while macroscopic ones such as Schrödinger’s cat behave classically simply because the (newly postulated) laws of nature say so. By changing the dynamics, collapse theories make predictions that are different from quantum-mechanical predictions. Then it becomes interesting to test the various collapse models that have been proposed. Experimental effort is increasing worldwide, so far limiting values of the theory’s parameters quantifying the collapse, since no collapse signal was detected, but possibly in the future finding such a signal and opening up a window beyond quantum theory.

Understanding the nature and the structure of human language coincides with capturing the constraints which make a conceivable language possible or, equivalently, with discovering whether there can be any impossible languages at all. This book explores these related issues, paralleling the effort of a biologist who attempts at describing the class of impossible animals. In biology, one can appeal for example to physical laws of nature (such as entropy or gravity) but when it comes to language the path becomes intricate and difficult for the physical laws cannot be exploited. In linguistics, in fact, there are two distinct empirical domains to explore: on the one hand, the formal domain of syntax, where different languages are compared trying to understand how much they can differ; on the other, the neurobiological domain, where the flow of information through the complex neural networks and the electric code exploited by neurons is uncovered and measured. By referring to the most advanced experiments in Neurolinguistics the book in fact offers an updated descriptions of modern linguistics and allows the reader to formulate new and surprising questions. Moreover, since syntax - the capacity to generate novel structures (sentences) by recombining a finite set of elements (words) - is the fingerprint of all and only human languages this books ultimately deals with the fundamental questions which characterize the search for our origins.

1. In many problems in theoretical physics one encounters situations in which it is desirable to be able to expand orbitals centred at one particle about another centre, frequently, but not always, another particle.There have long been available methods for permitting this to be effected for bound states but no such procedures are available for the continuum.Typical examples of physical situations in which such procedures are desirable are positron scattering from atomic and molecular systems, electron scattering from molecules, and nucleon scattering from light nuclei, to mention only a few.The author's interest arose from a desire to establish a general theory of slow electron scattering from molecules, and an account of such a theory will appear shortly (1).

The process of teaching physics at a medical university is developing within the framework of a fairly rigid modern educational paradigm. On the one hand, there is a steady reduction in the study time allotted to the academic discipline, both lecture hours and hours of practical training. On the other hand, the role and place of physics as the basis of radiation medicine in the health care system, and specifically in medical diagnostics, is constantly growing. In addition, modern physics, following in the wake of the advanced achievements of science and technology, is actively replenished with new technologies and teaching methods, which leads to a significant increase in the material required for assimilation. There is no doubt that this problem is not specific to physics and therefore its solution is not in the plane of increasing the volume of hours at the expense of other disciplines. Innovative approaches are required that take into account modern realities and general trends in the development of the educational process.
