Number theorists, where it's their theory, of numbers,
sometimes do indeed posit a "point at infinity", as
a member, or "one-point compactification", of what
are their "natural numbers".

That "the naturals are compact" is along the lines
of like "the reals are projectively well-ordered"
with regards to that there are models of the integers,
where it is so.

Where it is so, ....

Then with regards to theories of atomism while in the
meso-scale things are divisible, has that it's among
classical theories and complementary duals and you'd
be well advised to be aware of them in settings where
the topics are science, physics, mathematics, logic, ....
