The n'th ball is removed at 1/2^(n -1) minus before noon.

Which ball(s) does TO suggest remain at noon.

Consider this modification of the "game", TO.

All the balls are in the vase to start with, one for each natural
number.

At one minute to noon ball 1 is removed.
At 1/2 minute to noon, ball 2 is removed.
At 1/4 minute to noon, balll 3 is removed.
.....
At 1/2^(n-1) minutes to noon, ball n is removed.
.....


How many balls are left at noon?

The only reasonable answer is none!

But at every time before noon, there are infinitely many more balls in
the vase than in the previous problem of adding 10 and removing 1.
