Boltzmann's Entropy and Time's Arrow [PDF]

open access: possiblePhysics 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.

State-to-State Cosmology: A New View on the Cosmological Arrow of Time and the Past Hypothesis

Foundations of physics, 2021
Cosmological boundary conditions for particles and fields are often discussed as a Cauchy problem, in which configurations and conjugate momenta are specified on an “initial” time slice.

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 ...
