Wherefore by their fruits ye shall know them (Matthew 7:20).
For example the Balls in a Vase problem clearly shows what nonsense is
the consequence of contemporary mathematical thinking. There is no need
for further argumentation.

Wrong: whether maths is a science or not, it is NOT grounded on dogma
(or better: mention one dogma of mathematics).
About maths being or not a (natural) science: I think that may depend
on what definition we use for "natural science". Maths doesn't require
labs, observation of physical phenomena or testing of results again and
again, just as chemistry, physics or biology may need, but maybe not
only that is what makes a science according to other definitions.
Anyway, I really don't care whether someone thinks maths is or not a
science.

I'll be candorously innocent...Han, please: what nonsense is that
you're talking about related to the vase balls problem, and how does it
come from "contemporary mathematical thinking"? And what would this
"contemporary mathematical thinking" be?
I wonder whether I'll get a response...

No, but what shocks me is that the tax payer has to pay money for such
ambiguous nonsense. The story of Tristram Shandy is similar to the
vase, even though the vase is more clear about limits. We know, not by
intuition, but by logic, that the vase at any time contains more balls
than have escaped. And of course, this is also valid too for noon, if
omega transactions is a meaningful notion at all. To assert that at
noon (finished infinity, actualized transfinity) the vase is empty is
not counter-intuitive but it stupid.

Apply simply the knowledge that the contents of the vase grows, in
infinity. No axiom is powerful enough to yield the contrary. This story
only tells us that, if both sides of infinity are considered
1) Before noon every ball comes out of the vase
2) Before and at noon there are more balls in the vase than have come
out
then the axioms yield a contradiction.

It is nonsense, but it is the truth if infinity can be calculated. I
said it merely to show that actual infinity is not only a huge nonsens
but rather an infinite nonsense.

Of course you know (?) that the present day is the present day of X,
i.e. the day he lives. The present day is a variable. This variable is
never set to the value "written" but has always the value "not yet
written".
