Once I got to sixth form, I discovered that physics just clicked. Things worked. I could think about it and it made sense. I had an interest in time and cosmology, which didn’t really get followed up because I discovered lots of equations and how good at maths you need to be to be able to do those sorts of things. But the stars … I dunno, I’ve got a liking for pretty lights: stars, glow-worms, fireworks, thunder and lightning storms are all neat. Sparkly lights will keep me quiet for a while.
