In [[physics]], [[chemistry]], and [[materials science]], '''percolation''' ({{etymology|la|{{wikt-lang|la|percolare}}|to filter, trickle through}}) refers to the movement and [[filtration|filtering]] of fluids through porous materials. It is described by [[Darcy's law]]. Broader applications have since been developed that cover connectivity of many systems modeled as lattices or graphs, analogous to connectivity of lattice components in the filtration problem that modulates capacity for percolation.
