James Clerk Maxwell’s path to the Gaussian distribution

If a great many equal spherical particles were in motion in a perfectly elastic vessel, collisions would take place among the particles, and their velocities would be altered at every collision; so that after a certain time the vis viva [kinetic energy] will be divided among the particles according to some regular law. – James… Continue reading
