A recent Wired article addresses the question of whether computational physics is experiment or theory. Computational physics, also commonly called modeling or simulation, plays a large role in modern research, including my own.
If we agree on the fundamental ideas of science, then we can have a discussion on the role of computational science. Let me give the following (very brief) overview of science:
The Nature of Science: Science is all about models. We look at something in real life and try to make a model of it. We can use this model to predict future (or new) events in real life. If the model doesn’t agree with real data, we change the model. Repeat forever.
