There's something called "signaling theory" that has uncovered the "root mechanisms" of human relations and is comparable to calculus? That sounds like an absurd fantasy. I'll have to look it up.
As for 'root mechanisms', perhaps "mechanisms" wasn't precisely the right word, but it's up there with game theory. It is typically applied to animals observed in nature- yet that said, we too are animals, and it takes but a moment's thought to recognize it in action among humans.
disregard the seeming lack of relevance.
