Abstract

Thermodynamic entropy is a pathway for transitioning from the mechanical world of fundamental physics theory to the world of probabilities, statistics, microstates, and information theory as applied to analyses of the universe. This article explains the physical meaning of thermodynamic entropy, and its connection to Boltzmann’s entropy. The inclusion of Boltzmann’s constant in his definition of establishes the connection. The physical meaning of Boltzmann’s constant and his entropy are explained. These explanations first require new analyses of fundamental properties such as force and especially mass. It is strongly suggested that the reader of this article first read two other articles published by Acta and written by this author. The first explains the great importance of formally defining mass using the same correct, historical method used to define force, energy, and momentum. Its title is Calculating the Universal Gravitational Constant. Its ACTA Scientific link is Acta Scientific | International Open Library | Open Access Journals Publishing Group. The second article shows how very different fundamentally unified physics is from theoretical physics. Its title is A Unit of Absolute Universal Time. Its ACTA Scientific link is Acta Scientific | International Open Library | Open Access Journals Publishing Group.
