His statistical research into the velocity distribution of gas molecules extended the ideas of James Clerk Maxwell. Boltzmann's general law said a system will approach a state of thermodynamic equilibrium because this is the most probable state. He introduced the Boltzmann equation in 1877 relating the kinetic energy of a gas atom or molecule to temperature. The formula involves the gas constant per molecule called the Boltzmann constant. In 1884 he derived a law, often termed the Stefan-Boltzmann law, for blackbody radiation discovered by his Viennese teacher, Josef Stefan (1835-1893). After being attacked for his belief in the atomic theory of matter, Boltzmann committed suicide.
