Heat equation - Wikipedia
https://en.wikipedia.org/wiki/Heat_equationOne can model particle diffusion by an equation involving either: • the volumetric concentration of particles, denoted c, in the case of collective diffusion of a large number of particles, or• the probability density function associated with the position of a single particle, denoted P.
