Austrian physicist whose greatest achievement was in the development of statistical mechanics which explains and predicts how the properties of atoms (such as mass, charge, and structure) determine the visible properties of matter (such as viscosity, thermal conductivity, and diffusion).  He is renowned for his famous H-Theorem published in 1872.
