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)
“A fool, A fool! I met a fool i’ the forest,
A motley fool. A miserable world!
As I do live by food, I met a fool,
Who laid him down and basked him in the sun,
And railed on Lady Fortune in good terms,
In good set terms, and yet a motley fool.”
—William Shakespeare (1564–1616)
