Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics, behaviors and functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time - wikipedia 
Bret Victor worked at Apple (2007-2010) as a member of the “HID Proto” future-interface prototyping team, designing UI concepts for experimental hardware platforms.
After offhand remarks Bret Victor reflects deeply on the climate problem bearing upon us and the many ways that our technological attention could be better spent. site
A term coined by Alan Kay to describe a way of using computers. In Early History Of Smalltalk, Alan Kay explains how after seeing Seymour Papert's work with Logo Language he grew to see personal computing less as a "personal dynamic vehicle" and more as a "personal dynamic medium". Instead of the computer being primarily used for its capacity to perform computation, what if it were used as a medium for communication? Not just as a way for people to send each other text, or pictures, or sound, but as a way to send each other active, "live" simu
The ability to track games and simulations is becoming ever more important in EdTech.
Conversation becoming an improvised real-time simulation for exploring models of thought.
Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Often, computer experiments are used to study simulation models. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning, as in economics. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist.
Key issues in simulation include acquisition of valid source information about the relevant selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes. Procedures and protocols for model verification and validation are an ongoing field of academic study, refinement, research and development in simulations technology or practice, particularly in the field of computer simulation.
