Entropy, Information, and the Arrow of Time

Journal of Physical Chemistry B, 2010
We shall investigate the relationships between the thermodynamic entropy and information theory and the implications that can be drawn for the arrow of time. This demands a careful study of classical thermodynamics and a review of its fundamental concepts.

Entropy, inflation and the arrow of time

Classical and Quantum Gravity, 1991
One of the motivations for the introduction of inflation was to explain the large entropy of the observed Universe. Penrose has recently pointed out that the entropy of the observable Universe is small when compared with the maximal possible entropy. The authors show that this phenomenon is also a natural consequence of inflation.

Transfer entropy in physical systems and the arrow of time

Physical Review E, 2016
Recent developments have cemented the realization that many concepts and quantities in thermodynamics and information theory are shared. In this paper, we consider a highly relevant quantity in information theory and complex systems, the transfer entropy, and explore its thermodynamic role by considering the implications of time reversal upon it.

Boltzmann's Entropy and Time's Arrow

Physics Today, 1993
Given the success of Ludwig Boltzmann's statistical approach in explaining the observed irreversible behavior of macroscopic systems in a manner consistent with their reversible microscopic dynamics, it is quite surprising that there is still so much confusion about the problem of irreversibility.

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 ...
