The mission of the Department of Mathematics, Computer Science, and Statistics is to provide an excellent education in the theoretical, practical, and aesthetic aspects of mathematics, statistics, and computer science to undergraduate students. The Department of Mathematics, Computer Science, and Statistics offers an introduction to the concepts, structures, and techniques of the different fields of our three disciplines. It is the philosophy of the department that all students of the mathematical sciences should have an understanding of and appreciation for the theoretical aspects of the discipline as well as their far-reaching applications. The skills of analytic thinking and logical argument combined with the ability to communicate successfully provide the fundamentals of a good liberal arts education. Mathematics, statistics, and computer science are generally considered essential for persons interested in the natural and social sciences. A Mathematics, Computer Science, or Statistics major will be well prepared for graduate study, secondary school teaching, or employment in government or industry. Professional opportunities are available in all analytically oriented fields. The departmental computer facilities are located in a computer lab on the third floor of the Olin building.

Mathematics, Computer Science, and Statistics majors are encouraged to study abroad, and the department allows appropriate coursework from approved international programs to apply toward the major. This is particularly true for the Budapest Semester in Mathematics and the Budapest Semester in Computer Science.

***Note:** Normally, no more than three courses towards the major or one course toward the minor taken at other institutions may count. Students planning to take courses elsewhere, including those in Gustavus-approved international programs, should make prior arrangements with their departmental advisor and the chair of the department. Exceptions to these limits may be made on an individual basis.

## Mathematics

**Mathematics Major:** At least 11 courses. A grade of C– or higher is necessary in all courses used to satisfy the requirements of the major, which are as follows:

- MCS-122, MCS-150, MCS-220, MCS-221, and MCS-222.
- MCS-142 and MCS-177.
- An immersive sequence of two Level III courses. Approved sequences are

- MCS-303 and MCS-313 (reserved for mathematics education)
- A collaborative experience—a course which includes a significant component of collaborative work in groups. Approved collaborative experiences are

MCS-358, MCS-355, and MCS-270. MCS-344: Advanced Topics in Mathematics can be used to satisfy this requirement, upon approval by the department. An approved internship or summer research opportunity may also be used to satisfy this requirement. Students choosing this latter option must register for MCS-368 (1 course) prior to the internship or research experience. - One additional course chosen from MCS-303, MCS-313, MCS-314, MCS-321, MCS-331, MCS-344, MCS-350, MCS-353, MCS-355, MCS-357, and MCS-391.

Mathematics Teaching majors must complete all Mathematics major requirements, including MCS-303 and MCS-313 (requirement 3a), and all courses required for licensure, including student teaching (see Department of Education).

**Mathematics Minor:** 6 courses. A grade of C- or higher is necessary in all courses used to satisfy the requirements of the minor, which are as follows:

## Mathematics Honors Program

In order to graduate with Honors in Mathematics, a student must complete an application for admission to the Honors program, available through the department chair, showing that the student satisfies the admission requirements, and then the requirements of the program.

The requirements for admission to the Honors program are as follows:

- Completion of MCS-122, MCS-221, MCS-150, MCS-220 MCS-222, MCS-222, MCS-142, and MCS-177 with a grade point average greater than 3.14.
- Approval by the Mathematics Honors committee of an Honors thesis proposal. (Guidelines are available in the Mathematics Advising Guide.)

The requirements of the honors program after admission are as follows:

- Attainment of a GPA greater than 3.14 in courses used to satisfy the requirements of the major. If a student has taken more courses than the major requires, that student may designate for consideration any collection of courses satisfying the requirements of the major.
- Approval by the Mathematics Honors Committee of an Honors thesis. The thesis should conform in general outline to the previously approved proposal (or an approved substitute proposal), should include approximately 160 hours of work, and should result in an approved written document. Students completing this requirement will receive credit for the course MCS-350, whether or not they graduate with Honors. (See the Mathematics Advising Guide for the thesis guidelines.)
- Oral presentation of the thesis in a public forum, such as the departmental seminar. This presentation will not be evaluated as a criterion for thesis approval, but is required.
