History of Entropy - Statistical Thermodynamic Views

Statistical Thermodynamic Views

In 1877, Ludwig Boltzmann formulated the alternative definition of entropy S defined as:

where

kB is Boltzmann's constant and
Ω is the number of microstates consistent with the given macrostate.

Boltzmann saw entropy as a measure of statistical "mixedupness" or disorder. This concept was soon refined by J. Willard Gibbs, and is now regarded as one of the cornerstones of the theory of statistical mechanics.

Famous quotes containing the word views:

    Meek young men grow up in libraries, believing it their duty to accept the views which Cicero, which Locke, which Bacon, have given, forgetful that Cicero, Locke, and Bacon were only young men in libraries, when they wrote these books. Hence, instead of Man Thinking, we have the book-worm.
    Ralph Waldo Emerson (1803–1882)
