What is the importance of computational physics?
Introduction Computational physics has been an important research tool in physics for over 40 years. It has enabled physicists to understand complex problems more completely compared to using theoretical and experimental methods alone.

Why are computational models useful?
Computational models are an invaluable tool in modern biology. They provide a framework within which to summarize existing knowledge, enable competing hypotheses to be compared qualitatively and quantitatively, and to facilitate the interpretation of complex data.
What are simulations in physics?
A physics simulation is a recreation of a real-world occurrence. These simulations could be in the real world, in a virtual environment by using a physics engine, or partially in both. The existence of virtual simulation brought about a field of simulation-based physics.
What are the advantages of computational models over verbal explanations?
In a computational model you can control many more variables much more precisely than you can with a real system, and you can replicate results precisely. This enables you to explore the causal role of different components in ways that would otherwise be impossible.
What is computation as simulation?
Definition A computational simulation is a dynamic, process-oriented model instantiated on a computer. These can range from traditional economic models (expressed as equations) to more abstract constructs and processes (expressed as objects, agents, operators and algorithms).
What is simulation and why use simulation?
A simulation is the re-creation of a real world process in a controlled environment. It involves creating laws and models to represent the world, and then running those models to see what happens. Simulations are used for scientific exploration, for safety tests, and to create graphics for video games and movies.
