Because I can.
Because I'm not going to blog at all if I make too many rules.
Because real life doesn't come in chapters and stanzas, however much we may mould it into them.
It's people wanting me to explain the homework from courses I've never heard of. It's about planning to spend a morning doing computer science, but leaving your flash drive at home and arguing about CSS and open source software in the labs instead. It's about being thrilled that the Pottermore beta has opened, but too busy writing Mathematica code to keep up with all the excitement.
It's about wanting to study at Cambridge, but being afraid of moving halfway across the city. It's about being soon-to-move-out, but not changing your own light bulbs. It's about joyful abundance and mountains of homework being almost the same thing. It's about adoring mathematical physics in the same breath you call it an oxymoron, because no physicist can be mathematical.
And then it's about wondering if you really mean what you just said. About thinking that some physicists might be able to do maths and that enough homework to keep you busy might not quitebe mountains. About thinking you hold the world in the palm of your hand and that you'll never achieve anything; about confronting the impossible, the paradoxical, the unthinkable.
It's about something more real than our fragile, finite brains can dream up.
