Percolation

For people who check facts
This article is a stub. You can help Wikipedia by expanding it.

In chemistry and other physical sciences, percolation is a type of filtering. An abstract mathematical model of percolation can be applied to other processes, which are then also called percolation, that share the mathematical description in common with the filtering process. For that abstract treatment, see percolation theory.
