===Computer simulation===
[[Computer simulation]] is a computer program, or network of computers, that attempts to [[simulation|simulate]] an abstract [[model (abstract)|model]] of a particular system. Computer simulations have become a useful part of [[mathematical model]]ling of many natural systems in physics, and computational physics, chemistry and biology; human systems in economics, psychology, and social science; and in the process of engineering and new technology, to gain insight into the operation of those systems, or to observe their behavior.<ref>

Computer simulations vary from computer programs that run a few minutes, to network-based groups of computers running for hours, to ongoing simulations that run for months. The scale of events being simulated by computer simulations has far exceeded anything possible (or perhaps even imaginable) using the traditional paper-and-pencil [[mathematical modeling]]: over 10 years ago, a desert-battle simulation, of one force invading another, involved the modeling of 66,239 tanks, trucks and other vehicles on simulated terrain around [[Kuwait]], using multiple supercomputers in the [[United States Department of Defense|DoD]] [[High Performance Computing Modernization Program]].<ref name="JPLsim">[http://www.jpl.nasa.gov/releases/97/military.html "Researchers stage largest military simulation ever"].
