In what sense is zero not a quantity?
A quantity is an amount. Nothing is the absence of amount. While we use 0 as if it were an amount, and sentences that use it are understood quite well, it changes not that nothing is not the something required to have an amount.
would you consider the empty set a set
I do not know set theory.
I think it'd be more accurate to say that it's NULL to NULL
I guess that humor doesn't work on you. Congratulations, you broke the joke.
