Astronomy, Natural sciences The point where the orbit of a planet, as viewed from the Sun, intersects the ecliptic. The ascending and descending nodes refer respectively to the points where the planet moves from South to North and N to S; their respective symbols are ☊ and ☋.

Biology, Botany, Natural sciences A leaf node.

Computing, Engineering, Mathematics, Natural sciences, Networking, Physical sciences, Sciences A computer or other device attached to a network.

Engineering, Natural sciences, Physical sciences The point at which the lines of a funicular machine meet from different angular directions.

Geometry, Mathematics, Sciences The point at which a curve crosses itself, being a double point of the curve. See crunode and acnode.

Geometry, Mathematics, Sciences A similar point on a surface, where there is more than one tangent-plane.

Graph theory, Mathematics, Sciences A vertex or a leaf in a graph of a network, or other element in a data structure.
