In set theory, an infinite set is a set that is not a finite set. Infinite sets may be countable or uncountable. Some examples are:
- the set of all integers, {..., -1, 0, 1, 2, ...}, is a countably infinite set; and
- the set of all real numbers is an uncountably infinite set.

Famous quotes containing the words infinite and/or set:
“Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.”
—Epicurus (c. 341–271 B.C.)
“The sun set; but set not his hope:
Stars rose; his faith was earlier up:
Fixed on the enormous galaxy,
Deeper and older seemed his eye:
And matched his sufferance sublime
The taciturnity of time.”
—Ralph Waldo Emerson (1803–1882)
