arXiv:2405.13421v1 Announce Type: new Abstract: The positivistic assumptions of determinism and objectivism in the realm of Newtonian mechanics are questioned in this paper. While objectivism is only challenged through proposing the mildest form of subjectivism, determinism is structurally disputed by proposing that the physical reality, at least in the examples discussed, is, in essence, probabilistic and unpredictable. It is discussed that the physical reality and experimenter’s identification of it could basically have inconsistent characteristics, and the study of the physical reality can therefore be conducted in ontic and epistemic levels, leading to two distinct identifications. Four scientific topics, showing two different types of indeterminacy, are introduced and briefly reviewed: chaotic systems, turbulence, fluid transport in porous media, and hydromechanics of fractures. It is proposed that determinism is only meaningful in epistemic level, the first two examples are ontically indeterministic, the last two examples are epistemically indeterministic, and more examples of indeterministic phenomena could, most likely, be found in the nature. Indeterminacy of the physical reality, it is discussed, has always been considered in engineering design processes and such effects have normally been covered through safety factors and feedback loops. By reviewing Hadamard’s well-posedness criteria, Poincae’s complete deterministic approach, and Leibniz’s principles of sufficient reason and identity of indiscernibles, it is claimed that positivism stands on Leibniz’s metaphysical assumptions, which are not necessarily in full agreement with the physical reality. A few suggestions for a path beyond positivism in Newtonian mechanics are finally provided.

arXiv:1709.09508v4 Announce Type: replace Abstract: Scholars of the history and philosophy of science have asked what would decolonized science would look like. This paper develops an answer by interrogating the assumption that observations need to be recorded and communicated using the language of classical physics. Niels Bohr held this assumption even though he recognized the fact that quantum phenomena cannot be analyzed on classical lines. Classical analysis requires the objectification of whatever is being observed so that it can be objectively described. Inherent in this analysis is the intellectual creation of a transcendental verity, a view from nowhere. In contrast, knowledge systems that predate European colonialism make use of the quantum nature of nature without constructing an objective model of it. This paper concludes that uncolonized knowledge systems differ from classical ones in that they are epistemically plural, accepting multiple true observations of the same phenomenon.

arXiv:2405.13373v1 Announce Type: new Abstract: We numerically calculate the spacetime describing the formation and evaporation of a regular black hole in 2D dilaton gravity. The apparent horizons evaporate smoothly in finite time to form a compact trapped region. The spacetime is asymptotically flat at future null infinity and is free of singularities and global horizons. We nevertheless see rich dynamics; an anti-trapped region forms alongside the black hole, and additional compact trapped/anti-trapped regions are formed by backreaction effects as the mass radiates away. These results suggest that the evaporation of regular 2D black holes is unitary.
