Best Answer

Some physicist (experimentalists) work in a laboratory and do a lot of measurements. Other physicist (theoreticians) do not need complicated devices and expensive equipment to do research: a piece of paper and a pencil is enough for them to do their calculations.

Computational physics is between the two: Computers can be used for modelling natural phenomena. The scientists can control every aspect of these computer models, so they have much tighter control than experimentalists. Moreover, they can model very complicated phenomena on computers, phenomena that cannot be studied with the purely mathematical tools of theoreticians. The disadvantages are that the results that can be obtained from these models are not as general and not as precise as the theoretician's formulae, and that the models do not correspond exactly to the real world that experimentalists study.

You could do worse than consider the 15 science divisions at the head of the SCIENCE subdivision in this answers.com. That will give you a good start. You'll find that several of the primary divisions in science have, in turn, subdivisions below them.


What is the importance of computational physics?

That rather puts the cart before the horse. The computer is important, but only as a tool to make possible extremely complex predictive and analytical models and calculations. So the Physics is the important bit. The computer is a research tool.
