An equation named for this scientist governs the time-evolution of the phase-space distribution function for a system of particles and contains force, diffusion, and collision terms. At zero chemical potential, Gibbs factors equal this scientist’s factors, which equal the exponential of minus E over kT. A constant named for this scientist relates temperature (-5[1])to kinetic energy by the equipartition theorem. This scientist’s tombstone is engraved with the equation “S equals k log W,” which sets entropy proportional to the log of the number of microstates. For 10 points, what Austrian “father of statistical (10[1])mechanics” (10[1])co-names a distribution of particle speeds (10[1])with James Clerk (“clark”) Maxwell? ■END■ (10[2])
