Yes, it is a distinct sequence of events. Each ball is involved
in exactly two events. Ball #n is added at time -(1/2)^(floor(n/10)

The argument does not rely on set theory. Every ball that
is added before noon is removed before noon. This is a simple
consequence of the fact that for every n,
if -(1/2)^(floor(n/10)) <0
then
-(1/2)^n < 0

You have never presented any sort of refutation for that
argument, and instead are just responding with lame
insults.

Indeed, and each iteration of the sequence is involved with 10-1 balls.
Which logic seems to have more of a flaw, when they conflict?

For every "n e N". No, that's not set theory. No way.

The concept that everything that went in also came out is based, as WM
would put it, on the concept of a completed infinity. The condensation
point at "noon" is a Zeno machine, design for the express purpose of
producing a paradox.

What are you on? I have presented more than one argument showing that
what you claim is false.

If only one ball can be removed at any time, and the vase becomes empty,
then there has to have been a single ball removed which produced that
result. Of course, it had ten added before it, so there have to have
been -9 balls in the vase before then. That's obviously incorrect.

The problem is precisely characterized as an infinite series which
diverges. There is no discontinuity at noon, as expressed in the problem
itself. That's a transfinitological obfuscation.

Have a nice day!

Hi David!

Well, thanks for that elucidating example. It's all blindingly obvious
now. :)

Yes, for that particular ball, you have described its state over time.
According to your rule, A(10)=0, since 10>6>5. Do go on.

The formula for the number of balls after each iteration is linear. It
does not change direction. While the set may be discrete, the formula
mapping the set from the naturals is continuous in the reals. Either you
see the significance of this, or you don't, I suppose.

You miss the point, as usual. One can look at this in time, in which
case the iterations all become squashed together at noon and
indistinguishable. Or, one can look at this in iterations, in which case
the sum clearly diverges. The Zeno machine is a deliberate attempt to
produce a paradox. Ho hum.

ZF and NBG don't handle sequences or their sums, but only unordered
sets, so they really have nothing to say on the matter.
