Chaos Theory: Chaos theory is an area of deterministic dynamics proposing that seemingly random events can result from normal equations because of the complexity of the systems involved. Chaos, with reference to chaos theory, refers to an apparent lack of order in a system that nevertheless obeys particular laws or rules. The two main components of chaos theory are the idea that systems - no matter how complex they may be - rely upon an underlying order, and that very simple or small systems and events can cause very complex behaviors or events.
