George Box once said “All models are wrong, but some are useful.” As we build up our understanding of the world around us, we find different parts of our maps fall short of the territory. Sometimes our predictions end up out of joint with reality, but sometimes we just can’t stand how inelegant our approximation is. We’re getting the right answers, but we suspect we haven’t actually hit on why yet. And we suspect that missing the beauty of the big picture will eventually lead us astray.
And I like living in a world where twice a year we get to have a fight about the aesthetics of two different ways of talking about math. You can read Tau’s side of the story here.
