Simulations
Computer simulations are programs that attempt to replicate real life situations. Using mathematical formulae, they can be used to explore situations and concepts that may be difficult or dangerous to attempt in real life.
For example, at pilot school a flight simulator is used to enable pilots to learn how to land a plane during a storm.
The difference between a model and a simulation is that a simulation uses something physical to mimic or copy the system.
A common example of a simulation would be a thrill ride simulator found in theme parks like Universal Studios in Florida. Another form of simulation is Virtual Reality.
Virtual Reality
Virtual Reality (VR) isn't just about gaming. It is being used in many different scenarios in medicine including treating post-traumatic stress or phobias where VR is used to help patients face their fears in a controlled and supportive environment. It is being used also with Three Dimensional modelling is the process of creating a model or representation of an object that has width, depth and height to train surgeons across many areas of medicine and remove the risk of practicing on real patients.
VR can also be used in education. Examples include: Experiencing experiments or dissections that are difficult to perform in the classroom, going on virtual field trips for Geography or Biology, or visiting a museum or battle site for History.
