Collection: Boltzmann's Entropy Formula

In statistical mechanics, Boltzmann’s equation (also known as Boltzmann-Planck equation) is a probability equation relating the entropy of an ideal gas to the quantity W, the number of real microstates corresponding to the gas’s microstate.

In short, the Boltzmann formula shows the relationship between entropy and the number of ways the atoms or molecules of a certain kind of thermodynamic system can be arranged.

The equation was originally formulated by Ludwig Boltzmann between 1872 and 1875, but later put into its current form by Max Planck in about 1900. To quote Planck, “the logarithmic connection between entropy and probability was first stated by L. Boltzmann in his kinetic theory of gases”.

This is an exact replica of the equation written on Boltzmann’s grave in the Zentralfriedhof, Vienna.
