Infinity
Origin: L. Infinitas; pref. In- not – finis boundary, limit, end: cf. F. Infinite. See Finite.
1. Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity. There can not be more infinities than one; for one of them would limit the other. (Sir W. Raleigh)
2. Unlimited capacity, energy, excellence, or knowledge; as, the infinity of god and his perfections.
3. Endless or indefinite number; great multitude; as an infinity of beauties.
4. (Science: mathematics) a quantity greater than any assignable quantity of the same kind.
Mathematically considered, infinity is always a limit of a variable quantity, resulting from a particular supposition made upon the varying element which enters it.
5. (Science: geometry) That part of a line, or of a plane, or of space, which is infinitely distant. In modern geometry, parallel lines or planes are sometimes treated as lines or planes meeting at infinity.
