The article is devoted to the problem of time in modern science, where in recent years there have been major changes related to the latest discoveries in the field of the foundations of quantum theory. The author refers to works of K.-F. von Weizsacker (which works are not well-known in Russian-speaking field). Weizsacker deploys a large-scale program of building modern physics, while starting (not only as a physicist, but also a professional philosopher) with questions of philosophical interpretation of postulates of modern physics, especially quantum mechanics. His key thesis is that time in physics is fundamentally distinct, which represents the whole physics as an integral scientific discipline. Weizsacker comes from physical and philosophical reflections, that give a special value to his work. Analyzing the conclusions of theoretical physics, namely the issues of substantiation of statistical mechanics, thermodynamics, and, above all, quantum mechanics, Weizsacker comes to the key idea of the structure of time in the substantiation of physical theory. The author in this conclusion disagrees with the opinion of most modern physicists that time has a subjective character, and the modus of the past, present and future reflects its essential character. The allocation of the time structure requires special logic. Such a logic is temporal and quantum. Starting from temporal logic, introducing the concept of possibility and probability, he comes to the substantiation of quantum mechanics. Being modal logic, it is based on the concept of possibility and probability. Key concept for Weizsacker is a binary alternative (Uralternative), closely related to the principle of superposition in quantum mechanics. By introducing the concept of certain alternatives, essentially actualized alternatives, Weizsacker shows how one can get the theory of relativity with its space-time structure. Further, he shows that based on its structure, you can get the theory of relativity. The space-time structure in this case is secondary, relational, as understood by Leibniz, Mach, and Einstein.
This paper constitutes a background to the paper 'Quantum mechanics as space-time statistical mechanics?', arXiv:quant-ph/0501133, presented previously by the author. But it is also a free-standing and self-contained paper. The purpose of this paper is to give the reader an increased and a deeper understanding of the special theory of relativity, and the ideas lying behind the above mentioned paper. We will here consider, discuss, define, analyse, and explain things such as, e.g., the constancy of the speed of light, synchronization, simultaneity, absolute simultaneity, absolute space and time, the ether, and spacetime. Albert Einstein's original version of the special theory of relativity is fundamentally an operational theory, free from interpretation. But the old Lorentzian interpretation and the standard spacetime interpretation of the special theory of relativity will also be considered. This paper also discusses and analyses aspects of the philosophy of science that in my opinion are relevant for an understanding of the special theory of relativity.
With the expansion of science, philosophy appeared to be limited more than ever on a methodology, a logical guide useful for correctness validation of scientific knowledge. Quantum mechanics makes for the first time an ontological background starting from its own ontological potential solidary with the basic axioms of its mathematic formalism. The article aims to review a series of new projects of contemporary philosophy which we called quantum metaphysics; both philosophical projects, among which we mention Ortophysics proposed by Mihai Draganescu. To complete the hermeneutic dimension we reinterpreted a series of contemporary scientific theories appreciating their cultural implications, either by juxtaposition or by contraposition with recurring ideas in the history of philosophy or religious beliefs.
First Published in 1982 Philosophy and the New Physics is a compact and yet remarkably rich excursion through the history of physics from Newtonian mechanics to quantum physics. The theory of relativity, quantum mechanics and ideas about the ‘fundamental constituents’ of matter have attracted a great deal of philosophical comment. Indeed, the originators of some of these theories thought they were solving philosophical problems as well as scientific ones. Classical physics is often portrayed as epitomizing ‘mechanistic materialism’, and the revolution in modern physics is variously claimed to vindicate ‘logical positivism’, ‘operationalism’, ‘organicism’, ‘dialectical materialism’ and ‘Buddhist metaphysics’. In this book Jonathan Powers criticizes all of these claims and argues that such varied and conflicting interpretations are possible because of ineradicable elements of conventionality in scientific theories. This is a must read for scholars and researchers of philosophy of science and philosophy in general.
Motion is simply the manner in which objects transform their location with time. In this paper I have provided a brief overview of the theories explaining motion, its history starting with the ancient conceptions of Galileo and Newton and all the way up to the relativity theory of Einstein and the modern quantum mechanics. Considering the approach of kinematics, dynamics, and the more recent theories, I would like to show how our understanding of motion has evolved to become so simple and super complex so as to enable us know the large as well as the tiny particles in the universe. Once we have discussed the classical era we move on to the major paradigm shifts of the 20th century which actually broke the biscuit of the Newtonian worldview. Starting with Einstein Special and General Relativity, which disturbed the concept of absolute simultaneity. Relativity is a vivid picture of a dynamic and interwoven space in which the speed of light remains the same to all people, and gravity ceases to be a force but rather a curvature of space.
