POINTSOURCE
Point source
A point source is a single identifiable localised source of something. A point source has negligible extent, distinguishing it from other source geometries. Sources are called point sources because in mathematical modeling, these sources can usually be approximated as a mathematical point to simplify analysis.The above text is a snippet from Wikipedia: Point source

point source
Noun
- a source of pollution, radiation, waves, fluid or other substance that has one specific location (and negligible physical extent, distinguishing a point source from other source geometries). In simulations they can often be approximated using mathematical point sources.
- the abstract concept of a singularity emitting a flux or flow. A source with infinitesimal dimensions in space.
