Having understood what is meant by determinism, initial conditions, and uncertainty of measurements, you can now learn about dynamical instability, which to most physicists is the same in meaning as chaos. Because long-term mathematical predictions made for chaotic systems are no more accurate that random chance, the equations of motion can yield only short-term predictions with any degree of accuracy. At the time of its discovery, the phenomenon of chaotic motion was considered a mathematical oddity. In the decades since then, physicists have come to discover that chaotic behavior is much more widespread, and may even be the norm in the universe. Thus the presence of chaotic systems in nature seems to place a limit on our ability to apply deterministic physical laws to predict motions with any degree of certainty. The discovery of chaos seems to imply that randomness lurks at the core of any deterministic model of the universe. One of the most interesting issues in the study of chaotic systems is whether or not the presence of chaos may actually produce ordered structures and patterns on a larger scale. Some scientists have come to believe that the presence of chaos in physics is what gives the universe its "arrow of time," the irreversible flow from the past to the future.
