1Q84 and Math

I made the "mistake" of picking up ichi Q hachi yon by Haruki Murakami. Of course I cannot put it down. Here is Tengo on Math:

"Math is like water. It has a lot of difficult theories, of course, but its basic logic is very simple. Just as water flows from high to low over the shortest possible distance, figures can only flow in one direction. You just have to keep your eye on them for the route to reveal itself. That's all it takes. You don't have to do a thing. Just concentrate your attention and keep your eyes open, and the figures make everything clear to you."
