Our science history tells that we human have been arguing and debating on the nature and definition of “potential infinite and actual infinite” for at least 2500 years since Zeno’ time, and there are still no results nowadays. So, when facing “infinite things” in present classical infinite related science theory system, no one is sure whether they are “potential infinite things” or “actual infinite things” and are not sure how to treat them scientifically------- many suspended old and new infinite related paradox families are produced (such as 2500-year old Zeno’s Achilles--Turtle Race Paradox and so many modern versions of Zeno’s Achilles--Turtle Race Paradox, Russell's Paradox and so many modern versions of Russell's Paradox, …)by the confusing of “potential infinite and actual infinite” and these paradox family members are surely unsolvable in present classical infinite related mathematics where they were produced and nourished.

One may say “look at the history of mathematics and don’t mind the arguing and debating on the nature and definition of potential infinite and actual infinite, our mathematics goes well without the definition of infinite, just close one eye and open another eye in the field of infinite and we are used to this since Zeno’ time”.

But the facts are: more and more suspended infinite related paradox families are produced by the “confusing of potential infinite and actual infinite” such as infinitesimal relating paradoxes in analysis, infinity relating paradoxes in set theory, both infinitesimal and infinity relating paradoxes in the ideas and skills of “Cantor’s diagonal-contradictory proofs and the conclusion on “Real Number Set has more elements than Natural Number Set (infinite elements in Real Number Set is more infinite than that in Natural Number Set-------Infinite R is more infinite than Infinite N)”.

Can we really just close one eye and open another eye in the field of infinite and force us be used to the fundamental defects in our mathematics?

Trying our best to have scientific foundation for our mathematics is a must we should shoulder sooner or later beyond our will.
