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?

HZ: The Victorians really did a number on people. I feel like we're still unpicking Victorian attitudes.

KATE LISTER: Yes, we are. I mean, we're still very much the children of the Victorians, and they're a fascinating bunch, the Victorians. No generation, at no point in history, has sex been successfully repressed, ever. It just doesn't happen. But what you have is really strict social morality, conditioning and mores and constructs and power dynamics around sex that dictate what we are and what we're not supposed to be doing. And outward facing, they were so repressed and polite society and so offended by everything even remotely to do with sex, to the point of where they wouldn't say the word 'trousers' because they thought they were too rude. They were 'sit down upons'.
