Then let us change the experiment to include the insertion into the vase
of a cube at one minute after noon.

The experiment now ranges over [-1,1].

What are the contents of the vase at times in [0,1), TO?

TO is confused! Still or again? probably still, as there doesn't seem to
be much time at which he is not.

Those sets do not have natural number sizes, but do have a difference
set IN\OUT = {}.

Since there are no "moments" involved in the definitions on IN and OUT,
what happens at various "moments" is irrelevant.

You may or may not realize it, but this is /exactly/ how your arguments
come across in a mathematical context. Spark up that bowl! Party on,
