Then what is the sense to consider arbitrary large or small quantities?

Is there a need for new mathematics dealing with discrete (finite) objects?

OF COURSE there is no such thing as actual, physical "infinity" or "infinitesmal": mathematicians have been saying that for centuries.

That's completely irrelevant to the fact that approximating very large things (or large numbers of things) by infinity and approximating very small things by "infinitesmal" simplifies the calculation enormously.

Calculus (mathematics) is a TOOL. It does not necessarily represent physical reality.OF COURSE there is no such thing as actual, physical "infinity" or "infinitesmal": mathematicians have been saying that for centuries.
