Free electron Theory and Boltzmann Transport equation. This chapter presents a fast parallel Monte Carlo method to solve the radiative transport equation in inhomogeneous participating media for light and gamma photons. Light transport is relevant in computer graphics while higher-energy gamma photons play an essential role in medical or physical simulation., Variational Formula for the Relaxation Time in the Boltzmann Equation The Boltzmann equation,1 the work-horse of transport calculations2 in gas dynamics, solid-state physics, and related branches of investigation, is essential to the analysis of transport.

Boltzmann's equation (or Boltzmann-like equations) appears extensively in such disparate fields as laser scattering, solid-state physics, nuclear transport, and beyond the conventional boundaries of physics and engineering, in the fields of cellular proliferation and automobile traffic flow. is the Boltzmann transport equation shown below, where f is the unknown distribution function which, in its most general form, depends on a position vector r, a velocity vector v, and the time t. The quantity ∂f/∂t on the left side of Eq. (1) is the rate of change of f at fixed values of r and v.

However, one should be aware that the Boltzmann equation is not itself a “ﬁrst principle” of physics, but a low density limit of molecular dynamics. In the days of Maxwell and Boltzmann, and maybe even at the time of Hilbert’s own papers on the subject, this may not have been so clear to everyone.

is the Boltzmann transport equation shown below, where f is the unknown distribution function which, in its most general form, depends on a position vector r, a velocity vector v, and the time t. The quantity ∂f/∂t on the left side of Eq. (1) is the rate of change of f at fixed values of r and v. There are at least three equations named after Boltzmann. The first is the famous S=k\ln W, where S is the entropy, k is Boltzmann's constant, and W is the number of states accessible to the system. Boltzmann first wrote down his equation in 1872, although Planck was actually the first to write it in this form. This equation is inscribed on Boltzmann's tomb.

This paper relies on the following theses: (a) the analysis of the concept of diffuse motion is the theoretical leitmotiv of Boltzmann’s work during this period and, (b) the results obtained provide, at least from Boltzmann’s standpoint, the justification of two essential moves of the non-equilibrium theory in 1872: the collision mechanism This chapter presents a fast parallel Monte Carlo method to solve the radiative transport equation in inhomogeneous participating media for light and gamma photons. Light transport is relevant in computer graphics while higher-energy gamma photons play an essential role in medical or physical simulation.
