Boltzmannin

Boltzmannin is the Finnish genitive form of the surname Boltzmann and is used in Finnish to refer to things associated with Ludwig Boltzmann. The most common example is Boltzmannin vakio, the Boltzmann constant, a fundamental quantity in statistical mechanics that relates temperature to energy at the microscopic level.

Ludwig Eduard Boltzmann (1844–1906) was an Austrian physicist who helped establish statistical mechanics and the kinetic

Key contributions attributed to Boltzmann include the Boltzmann distribution, which describes the probability of a system

Boltzmannin vakio (k_B) is the proportionality constant between temperature and energy per degree of freedom; its
