Yeah it depends on the particular theory. Say, if you want to implement some physics model as a computer simulation. Often, physics is presented as a set of interconnected of equations (some are general, some are based on assumptions, representing special cases). Unfortunately, most of the time these equations are not built "bottom-up", so to speak. They do describe various aspects of physical reality, but often don't allow a nice computational/operational interpretation of it right away. So converting this knowledge into a computational model can be non-trivial.
