Simulation

A simulation is an imitation of the operation of a real-world process or system over time. Simulations are used in many aspects of science, technology, and engineering, such as simulation of climate change, simulation of the solar system, and simulation of the process of movement of electrons in a computer chip. In Hebrew, simulation is called מולטיפליקציה (mul'tiplikatsiya) or מולטיפליקציה של תהליך (mul'tiplikatsiya shel t'halikh). In French, it is called simulation, in German Simulation, in Spanish simulación, and in Japanese シミュレーション (shimyurēshon). Simulations are often used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unethical to engage. They are also used when the real system is too complex or expensive to implement for experimentation. Computer simulations are often used to study the behavior of dynamical systems, and to analyze and study phenomena in physics, chemistry, biology, geology, engineering, medicine, economics, social science, philosophy, psychology, and many other fields.
