The Maxwell-Boltzmann Distribution Brennan 5
alan.ece.gatech.eduMaxwell-Boltzmann Distribution Scottish physicist James Clerk Maxwell developed his kinetic theory of gases in 1859. Maxwell determined the distribution of velocities among the molecules of a gas. Maxwell's finding was later generalized in 1871 by a German physicist, Ludwig Boltzmann, to express the distribution of energies among the molecules.

ps.uci.eduThis is called the “Maxwell–Boltzmann distribution.” It is the same as our previous result when we applied the canonical distribution to N independent single particles in a classical system. The sum over r is a sum over single particle states. Alternative Derivation of Maxwell–Boltzmann Partition Function We can write the
