The most direct way to see what has gone wrong is to examine one of the “small metaphysics” difficulties that originally spawned theory T thinking. A paradigm exemplar can be found within the doctrinal tensions that Heinrich Hertz located within the elementary tenets of classical physics (a circumstance that is labeled as “the Mystery of Physics 101” here). Although seemingly innocuous in character, Hertz realized that these ambiguities impede a clear articulation of the conservation of energy and allied doctrines. He further recognized that these problems do not reside within simple misunderstandings of component words (such as “force”) but instead are holistically suffused through a much broader canvas of interlocked doctrine. The corrective cure he advocated attempts to whittle down such an overextended system to a self-consistent and axiomatized core. This two-pronged program—the rejection of individual word analysis and its pragmatic replacement by a single-leveled axiomatic corrective—forms the original inspiration for Carnap’s anti-metaphysical attitudes and the theory T conceptions of “rigor” that continue to dominate analytic philosophical presumption to the present day.

A simple example of classical physics may be defined as classical variables, p and q, and quantum physics may be defined as quantum operators, P and Q. The classical world of p&q, as it is currently understood, is truly disconnected from the quantum world, as it is currently understood. The process of quantization, for which there are several procedures, aims to promote a classical issue into a related quantum issue. In order to retain their physical connection, it becomes critical as to how to promote specific classical variables to associated specific quantum variables. This paper, which also serves as a review paper, leads the reader toward specific, but natural, procedures that promise to ensure that the classical and quantum choices are guaranteed a proper physical connection. Moreover, parallel procedures for fields, and even gravity, that connect classical and quantum physical regimes, will be introduced.

This study considers a variant of the realization of Dirac’s ideas regarding the limited number of Faraday force lines and allowance for the finite size of microparticles in physical theory. It is shown that within the framework of the classical approach, consideration of the limited number of Faraday force lines opens additional possibilities for describing and characterizing the physical field and associated phenomena. Specifically, it is shown that it becomes possible to obtain in a facile manner an expression for describing the discrete radiation of an atom, which agrees well with the empirical Balmer relation. An assumption is made about the possibility of the material existence of Faraday force lines as structural elements of the physical field. It is suggested that the natural fields of physical bodies can be considered as a set of materially existing lines of force, i.e., as a luminiferous ether.

In this paper, the problems existing in the concepts of Planck's energy element and Einstein's light quantum are analyzed, and the alternate concept of quantum and a new concept of electron transition power were proposed. This paper clarifies the common misunderstanding in classical electromagnetics that the electron will radiate electromagnetic wave when it moves around the nucleus in a uniform circular motion and points out that the electron will radiate and absorb electromagnetic waves only when it moves around the nucleus in an accelerated or decelerated motion with a change of frequency and expounds the classical physical mechanism of quantum generation. Based on this, the quantization of electron orbital energy level of hydrogen atom and the phenomenon of spectrum are explained without Bohr's “quantization hypothesis.” In addition, the photoelectric effect is explained by using the modified quantum concept. The modified quantum concept and its mechanism of classical physics break the gap between macro and micro physics, eliminate the contradiction between “classical physics” and “quantum mechanics,” and lay an important foundation for the reconstruction of unified macro and micro physics.

Determinism, causality, chance, free will and divine providence form a class of interlaced problems lying in three domains: philosophy, theology, and physics. Recent article by Dariusz Łukasiewicz in Roczniki Filozoficzne (no. 3, 2020) is a great example. Classical physics, that of Newton and Laplace, may lead to deism: God created the world, but then it goes like a mechanical clock. Quantum mechanics brought some “hope” for a rather naïve theology: God acts in gaps between quanta of indetermination. Obviously, any strict determinism jeopardizes the existence of free will. Yes, but only if human mind follows the laws of physics and only if nothing exists outside the physical limits of space and time. We argue that human action lies in-between two worlds: “earth” and “heavens” using the language of Genesis. In that immaterial world, outside time and space constraints, there is no place for the chain of deterministic events. We discuss, in turn, that the principle of causality, a superior law even in physics, reigns also in the non-material world. Though, determinism in the material universe and causality in both worlds seem to be sufficient conditions, to eliminate “chaotic”, or probabilistic causes from human (and divine) action.

The author considers artistic culture as a subject of synergetics and pre-quantum / quantum culture. The author’s reflections are in the field of searching theater, literature, performative art, and cinema. The theater of the future is the research subject, a “scientific” project. The level of the theater rises by an order of magnitude to its surpassing scenarios. Universalism, or rather, trans-professionalism, is becoming an indispensable component of the future artistic process. The leader, the Scientist–Researcher–Poet (Artist), becomes of current interest. The stage works by Castellucci, Suzuki, music by Scott Gibbons and others have modeled this future. Time moves simultaneously in all directions refuting the laws of classical physics. The trajectory of movement indicates quantum measurements. Faulkner, Joyce, Proust, Andre Gide, John Dos Passos, Rilke successfully polemicize with physics. The new dimensions of a person imply a plurality of identifications. Calvino – “The Cloven Viscount”.

AbstractWhen a solid object impacts on the surface of a liquid, extremely high pressure develops at the site of contact. Von Karman’s study of this classical physics problem showed that the pressure on the bottom surface of the impacting body approaches infinity for flat impacts. Yet, in contrast to the high pressures found from experience and in previous studies, we show that a flat-bottomed cylinder impacting a pool of liquid can decrease the local pressure sufficiently to cavitate the liquid. Cavitation occurs because the liquid is slightly compressible and impact creates large pressure waves that reflect from the free surface to form negative pressure regions. We find that an impact velocity as low as ~3 m/s suffices to cavitate the liquid and propose a new cavitation number to predict cavitation onset in low-speed solid-liquid impact-scenarios. These findings imply that localized cavitation could occur in impacts such as boat slamming, cliff jumping, and ocean landing of spacecraft.

A Sagnac interferometer has been a powerful tool for gyroscope, spectroscopy, and navigation based on the Sagnac effects between counterpropagating twin fields in a closed loop, whose difference phase is caused by Einstein’s special relativity. Here, a nonclassical version of a Sagnac interferometer is presented using completely different physics of coherence de Broglie waves (CBW) in a cavity, where CBW is a nonclassical feature overcoming the standard quantum limit governed by classical physics.
