Professional graduate schools (business, law, medicine) think it's a great major because they realize that studying mathematics develops analytical skills and the ability to work in a problem solving environment; these are skills and experience which rank high on their list of assets.

Whether you're interested in developing models and interpreting their results, or are interested in developing efficient algorithms to expedite known processes, mathematics and computer science are the tools of choice.

Models are needed to investigate air flow across the surface of aircraft wings, chemical and biological processes, astronomical trajectories and urban development. These models need to be designed, created, the data from them collected and analyzed, conclusions drawn and predictions made from them.
