"If the only tool you have is a hammer, everything looks like a nail". Most people shy away from simple math. In fact, publishers demand that no equations, however simply don't appear in popular books. From this perspective, the simple graphs and equations that appear in introductory textbooks appear sophisticated. In particular, these tools have a hard time presenting anything but a super simple, static picture of the world. If you approach the same situation with different tools, a very different picture emerges. Even simple computer simulations can show complex behavior that can't be reduced to equations of any sort. I played around with this idea a bit but abandoned it because it would have involved an unrealistic effort to implement it. However, even while simply drawing up a specification, you can see the kind of things a model could address. Most important is the question of stability or even a stable pattern of oscillation. Model specifications seem t...
