Although its use in common language is often vague, infinity is very important to mathematics and is used very precisely within a variety of contexts, from Greek paradoxes to the development of perspective in renaissance art.
It's usage is therefore dependent upon the context in which it is used. Zeeman outlines three typical examples:
Zeeman demonstrates the importance of infinity not only to mathematics, but also to the world of art, where its use in perspective is integral to conveying three dimensional spaces in two dimensional artworks.
