HZ: Zero, out of all the numbers and mathematical symbols, seems unique in being a combination of typographical marker and philosophical vortex. What makes it so special?
KYNE: It's a really interesting number because it's one of the newer numbers really. And there was lots of debate about whether it should count - no pun intended - as a number at all. What is a number in the first place? Can you give a definition without using the word number, like even a synonym, like quantity or amount?
HZ: Damn you, I was going to go 'quantity'!
KYNE: Right? I was like thinking about this earlier, so I wrote down my best definition. This is my best try: "A number is an abstract mathematical object used to describe things." So I know that definition uses the word 'mathematical', which I mean, in fairness is another tricky word to wrangle a definition out of. It's pretty clunky, I know, but...
HZ: You set that rule. You made it difficult you for yourself.
KYNE: I really encourage whoever's listening, try to ask yourself: how do you define a number?
