| | Thus, the solar **system** is a **dynamical** **system;** the United States economy is a **dynamical** **system;** the weather is a **dynamical** **system;** the human heart is a **dynamical** **system**. |

| | Mathematically speaking, a **dynamical** **system** is a **system** whose behavior at a given time depends, in some sense, on its behavior at one or more previous times. |

| | Furthermore, it is the task of the mathematical modeler to come up with a mathematical construct, a model, that will describe this relationship between current and past states of the **system** so that predictions about the future course of events for the **system** may be made with some degree of accuracy. |
