What is a simulation?
Q: What is a simulation?
A: A simulation is a way of seeing something happen without it actually taking place in the same way. It can be used to predict what might happen, show people what will happen next or what happened in the past, or even show what people believe is happening in a place or time where it is impossible to know what really happens.
Q: What are some examples of research institutions devoted to simulations?
A: Examples of research institutions devoted to simulations include The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES).
Q: Why are simulations used?
A: Simulations are used because they allow things to be controlled that might not be easy to control in real life. They can also use smaller versions of an object or system for testing or practice, and these smaller versions can simulate the real thing while being safer than the actual thing itself.
Q: How do computers help with simulations?
A: Computers are often used in simulations as they can make simulations of what a spaceship's route might be on the way to the moon, helping plan out missions and other activities safely and accurately before they take place.
Q: How did astronauts practice before going into space?
A: Astronauts practiced using simulations of outer space before they went there, such as practicing on moon-like terrain in swimming pools rather than actually going into outer space itself.
Q: Are all types of objects able to be simulated?
A: Yes, many different types of objects and systems can be simulated using smaller versions that still accurately represent how the real thing would act or behave if it were present instead.
