in·fi·nite (ĭn'fə-nĭt) adj.
[Middle English infinit, from Old French, from Latin īnfīnītus : in-, not; see in-1 + fīnītus, finite, from past participle of fīnīre, to limit; see finite.] in'fi·nite·ly adv., in'fi·nite·ness n. Synonyms: These adjectives mean being without beginning or end: infinite wisdom; boundless ambition; eternal beauty; illimitable space; sempiternal truth. See Also Synonyms at incalculable. Usage Note: Infinite is sometimes grouped with absolute terms such as unique, absolute, and omnipotent, since in its strict mathematical sense infiniteness is an absolute property; some infinite sets are smaller than others, but they are no less infinite. In nontechnical usage, of course, infinite is often used to refer to an unimaginably large degree or amount, and in these cases it is acceptable to modify or compare the word: Nothing could give me more infinite pleasure than to see you win. Withdrawing the troops would create an even more infinite set of problems for the coalition. · Note that unlike other incomparable adjectives, infinite when used in its strict literal sense cannot be modified by words like nearly, since quantities do not approach infinity by degrees. This constraint, too, can be ignored when the word is used simply to refer to a very large number: You need a nearly infinite amount of patience to do the job. See Usage Notes at absolute, unique. |
infinite mathematics
1. Bigger than any natural number. There are various formal set definitions in set theory: a set X is infinite if
(i) There is a bijection between X and a proper subset of X.
(ii) There is an injection from the set N of natural numbers to X.
(iii) There is an injection from each natural number n to X.
These definitions are not necessarily equivalent unless we accept the Axiom of Choice.
2. The length of a line extended indefinitely.
See also infinite loop, infinite set.
