As a Mathematics major, you employ a special language to describe the structure and attributes of objects, systems and processes in the universe, from the level of sub-atomic particles to that of planets and galaxies. You can contribute to mathematical knowledge for its own sake ( pure mathematics), or put your knowledge to work solving problems in a wide range of fields (applied mathematics). Grounding in mathematics is necessary to improve fuel efficiency, make faster planes, send people into space, predict the weather, develop new medicines and prosthetics, and understand how economies work.
