Macroscopic laws, microscopic dynamics, time's arrow and Boltzmann's entropy

Physica A: Statistical Mechanics and its Applications, 1993
Abstract I discuss Boltzmann's resolution of the apparent paradox: microscopic dynamics are time-symmetric but the behavior of macroscopic objects, composed of microscopic constituents, is time-asymmetric. Noting the great disparity between macroscales and microscales Boltzmann developed a statistical approach which explains the observed macroscopic ...

Time Reversal, Entropy Relativity, and Computational Naturalness: A Unified Perspective on the Arrow of Time

We investigate the fundamental nature of \emph{time‑reversal symmetry} and its progressive breakdown in complex, structured dynamical systems. Drawing on the fluctuation theorem and recent quantum time‑reversal experiments, we show that although microscopic laws remain reversible, the emergence of \emph{computational naturalness}, characterized by a ...

Timeless Quanta: A Threshold for Mass, Entropy, and the Arrow of Time

A single, parameter-fixed geometric framework is presented that unifies gravitational, quantum, and thermodynamic phenomena without introducing fitted constants. From a threshold curvature condition in a hybrid Gaussian–sech2 collapse geometry, particle masses, coupling constants, and entropy bounds are derived entirely from first principles.

Entropy, Information & the Arrow of Time in the Monadic Electron Universe

The study links entropy growth, time-irreversibility, and quantum entanglement to the topology of a single electron–positron world-line (“the monad”) that knots and links through space-time. A topological entropy S_topo is defined as the Boltzmann constant times the logarithm of the path-integral weight Omega(K) for each knot or link class K.

The Impossibility of Entropy Reversal: Energy Dispersion and the Arrow of Time

This paper offers a rigorous physical analysis of entropy, challenging common misconceptions that equate it with disorder or statistical abstraction. It argues that entropy is best understood as the irreversible dispersal of usable energy, governed by geometric principles and radiative loss.
