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)
“... many of the things which we deplore, the prevalence of tuberculosis, the mounting record of crime in certain sections of the country, are not due just to lack of education and to physical differences, but are due in great part to the basic fact of segregation which we have set up in this country and which warps and twists the lives not only of our Negro population, but sometimes of foreign born or even of religious groups.”
—Eleanor Roosevelt (1884–1962)
