Elementary Principles in Statistical Mechanics

Published in March 1902, this book by Josiah Willard Gibbs is a seminal work in the field of statistical mechanics.

It integrates the laws of thermodynamics with classical mechanics, introducing the concept of 'ensemble' which is a collection of indistinguishable replicas of a system.

Gibbs showed how statistical mechanics could be used to extend thermodynamics beyond classical systems, including microscopic and non-extensive systems.

The book remains a cornerstone in the field despite the advancements in modern physics.
