The Boltzmann equation describes the motion of particles in a fluid. If I&#x27;ve understood the opening section of the paper correctly (which I may not have done), other people have found solutions of the Boltzmann equation under some rather unrealistic assumptions about the distribution of relative velocities when particles collide. (AIUI you&#x27;re supposed to work out that distribution by doing some actual physics, then plug it into the equation; the solutions describe the behaviour of a fluid with the properties encoded in that distribution.)…</p><p><a href="https://hackerpaper.kaipfister.de/p/0912.0888/">Paper and discussion history</a>.
