Physics is nothing but modeling phenomena found in the world. Usually physicists use mathematical functions as their preferred class of models but they are free to use whatever they please. I don't believe there is a 'fundamental' science since it's all just modeling. Maybe the science of modeling is the most fundamental. Computer science, however, does seem to come closer to the 'study of models' then physics.
