Comment on "Entropy production and the arrow of time" [PDF]
arXiv, 2007 J.M.R. Parrondo at al. in arXiv:0904.1573 continue numerous efforts to unify the concepts of the arrow of time and entropy production with the concept of time invariance in physics. This is a wrong way.

Memory Systems, the Epistemic Arrow of Time, and the Second Law. [PDF]
Entropy (Basel), 2023 The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow

Journal of High Energy Physics, Gravitation and Cosmology, 2021 First, we do a Taylor series expansion of Entropy. Afterwards we define the arrow of time. After that, we define what terms we will analyze in the Taylor series expansion of entropy to help in finding initial conditions which may allow for the earliest possible identification of the Arrow of Time in cosmology. Definition of the arrow of time will allow

Entropy Production and Thermodynamic Arrow of Time in a Recollapsing Universe [PDF]
Nuovo Cim.B115:1039-1048,2000, 1999 We investigate the thermodynamic arrow of time in a time-symmetrically recollapsing universe by calculating quantum mechanically the entropy production of a massive scalar field. It is found that even though the Hamiltonian has a time-reversal symmetry with respect to the maximum expansion of the universe, the entropy production is generic and the ...

Influence of Thermodynamic Arrow of Time on Entropy
Physical Science International Journal, 2023 This study assessed the influence of thermodynamic arrow of time on entropy for boiled cooling water (physical process), the universe and the air (natural process). This was done by determining the entropies of boiled water, the universe and air. This was achieved by using 1.5 litres of pure water, a 2 liter electric kettle, a digital thermometer, a ...

Small and Simple Systems That Favor the Arrow of Time. [PDF]
Entropy (Basel), 2023 The 2nd law of thermodynamics yields an irreversible increase in entropy until thermal equilibrium is achieved. This irreversible increase is often assumed to require large and complex systems to emerge from the reversible microscopic laws of physics. We

Entropy, biological evolution and the psychological arrow of time [PDF]
arXiv, 2014 We argue that in Universes where future and past differ only by the entropy content a psychological arrow of time pointing in the direction of entropy increase can arise from natural selection in biological evolution. We show that this effect can be demonstrated in very simple toy computer simulations of evolution in an entropy increasing or decreasing

Journal of Physics: Conference Series, 2019 Abstract Using the Klauder enhanced quantization to specify the cosmological constant as a baseline for the mass of a graviton, we eventually develop with an initial degrees of freedom argument of about 1000, instead of 100 or so, implying no quantum fluctuations such as reversals in the arrow of time due to the size of initial black ...

Arrow of time: Metaphorical construals of entropy and the second law of thermodynamics
Science Education, 2012 AbstractVarious features of scientific discourse have been characterized in the science education literature, and challenges students face in appropriating these features have been explored. Using the framework of conceptual metaphor, this paper sought to identify explicit and implicit metaphors in pedagogical texts dealing with the concept of entropy ...
