In mathematics, a null set is a set that is negligible in some sense. For different applications, the meaning of "negligible" varies. In measure theory, any set of measure 0 is called a null set (or simply a measure-zero set). More generally, whenever an ideal is taken as understood, then a null set is any element of that ideal.
The remainder of this article discusses the measure-theoretic notion.

Famous quotes containing the words null and/or set:
“A strong person makes the law and custom null before his own will.”
—Ralph Waldo Emerson (1803–1882)
“One, two and many: flesh had made him blind,
Flesh had one pleasure only in the act,
Flesh set one purpose only in the mind—

Still those same terrors wherewith flesh was racked.”
