Vlasov's equation is a special case of an equation named after this man in which collisions are neglected, while another equation named after this man describes "almost rigid motion." An equation inscribed on his tombstone reads "S = k log W", where k is his namesake constant. A law stating that the energy radiated by a black body is proportional to the fourth power of temperature is named for Stefan and this man. For 10 points, name this Austrian scientist, one of the founders of statistical mechanics.
