Infinity vs. Finity — What's the Difference?

Infinity is that which is boundless or endless, or something that is larger than any real or natural number. It is often denoted by the infinity symbol shown here.

(uncountable) The state or characteristic of being limited in number or scope.

The state or quality of being infinite

(countable) Something which is limited in number or scope.

A number greater than any assignable quantity or countable number (symbol ∞)

The quality or condition of being infinite.

Unbounded space, time, or quantity.

An indefinitely large number or amount.

(Mathematics) The limit that a function  is said to approach at x = a when (x) is larger than any preassigned number for all x sufficiently near a.

A range in relation to an optical system, such as a camera lens, representing distances great enough that light rays reflected from objects within the range may be regarded as parallel.

A distance setting, as on a camera, beyond which the entire field is in focus.

(uncountable) endlessness, unlimitedness, absence of a beginning, end or limits to size.

A number that has an infinite numerical value that cannot be counted.

An idealised point which is said to be approached by sequences of values whose magnitudes increase without bound.

(uncountable) A number which is very large compared to some characteristic number. For example, in optics, an object which is much further away than the focal length of a lens is said to be "at infinity", as the distance of the image from the lens varies very little as the distance increases further.

The symbol ∞. Category:en:Infinity

Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity.

Unlimited capacity, energy, excellence, or knowledge; as, the infinity of God and his perfections.

Endless or indefinite number; great multitude; as an infinity of beauties.

A quantity greater than any assignable quantity of the same kind.

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.

Time without end
