A question I don't remember ever having been asked before:
Why do you love maths so much?
It's a really hard question to answer - if you asked someone why they like music or football, they'd probably shrug and say 'I just do!'
There are loads of things I love about maths - on one hand, it's this brilliant, creative game that's completely limitless and at the same time very strict about what you can do; and on the other, it's a huge set of tools you can use to understand the world better.
I love that you can do it anywhere, on restaurant napkins, in the margins of newspapers someone's left on the train, on envelopes, even (once, and for reasons I can't really remember) using fridge magnets.
I love battling against a puzzle until I find a solution, getting completely lost in different approaches, finding mistakes, putting them right, scratching my head, getting a flash of insight, realising I'm making it too complicated, simplifying...
But above all, I love the neatness of it - when a puzzle finally drops into place, or you spot a pattern you've seen somewhere before, and it all ties together like a detective novel...
It's glorious. And there's always another episode just around the corner.
