"WebThe Boltzmann equation was given by Ludwig Boltzmann in 1872. In modern literature, the term Boltzmann equation is often in use in a more general sense, referring to any kinetic equation that shows the change of a macroscopic quantity in a thermodynamic system. These quantities can be energy, charge or particle number. " - On the boltzmann equation
