The concept of infinity (symbol: ∞) appears in various branches of mathematics, philosophy1 and astronomy,2 in reference to a quantity without limit or finality, contrasted with the concept of finitude.3 In mathematics, infinity appears in various forms: in geometry, the point at infinity in projective geometry and the vanishing point in descriptive geometry; in mathematical analysis, infinite limits; and in set theory as transfinite numbers. All of these concepts are different and they do not all correspond to the same notion of infinity.
