There is only one real reason to major in mathematics: because you enjoy it. There are also lots of reasons that mathematics is an important subject. It is the language of science and technology. It has important applications and it is beautiful to those whose can appreciate its beauty. But ultimately, you should spend your precious time at Dartmouth doing something that moves you.

On the other hand, you may still want some more concrete reasons. I have collected a few documents here that others have written that may help.

• What are some recent majors doing now? We recently polled some of our past majors. Here is a survey summary. And a more complete list of survey responses.
