People look down on stuff like geography and meteorology, and not only because they're standing on one and being soaked by the other. They don't look quite like real science. But geography is only physics slowed down and with a few trees stuck on it, and meteorology is full of excitingly fashionable chaos and complexity. And summer isn't a time. It's a place as well. Summer is a moving creature and likes to go south for the winter.
Terry PratchettInteresting thing, these fellows never seem to get the idea of perspective-' The Bursar thought, or received the thought: that's because perspective is a lie. If I know a pond is round then why should I draw it oval? I will draw it round because round is true. Why should my brush lie to you just because my eye lies to me?
