    Can you see zero coffee cups?

    And if by "see" you mean something like "perceive visually" rather than something metaphorical (like "I see your point"), then you cannot in
    fact see zero. Visual perception applies to the physical world and its
    mental reflections (such as dreams, hallucinations, and vivid
    imaginings); zero and all other mathematical items are entirely abstract
    and non-physical. The numeral "0, the expression "4-3-1", and the
    english word "zero" are all *representations* of the abstract
    mathematical zero, not it itself.

    (There are those who think that zero and the other mathematical items do
    have a concrete non-physical existence in some ideal realm. This view
    is called "mathematical realism" or "Platonism". I am not of that view.)
