Chaos theory 
is a mathematical field studying deterministic laws and dynamical systems.
I would argue that humans are dynamical systems, which is why I include this page in this study.
Chaos theory gives us the vocabulary of Attractor Basins, an example of which is the Lorenz Attractor which says that climate orbits two attractor basins, one signifying cooling, and one signifying heating, and it does so in a "chaotic way" meaning it's hard to predict which attractor is in play at any given time.
We will return to Attractor Basins in various places in a study of conversations.
