Physics

Students may complete a major or minor in physics. Within the major, students may complete a minor in computational methods or educational studies, or complete the requirements for secondary education certification. Students may complete an M.A. in the combined A.B./M.A. program.

Faculty

Michael W. Noel, Assistant Professor

The courses in physics emphasize the concepts and techniques that have led to our present state of understanding of the physical universe. They are designed to relate the individual parts of physics to the whole rather than to treat them as separate disciplines. In the advanced courses, the student applies these concepts and techniques to increasingly independent studies of physical phenomena. Opportunities exist for interdisciplinary work, for participation by qualified majors in research with members of the faculty, and for training in electronics, instrumentation and experimentation, including computer interfacing and programming.

Required Introductory Courses for the Major and Minor

The introductory courses required for the physics major and minor are Physics 103, 104 or 101, 102 and Mathematics 101, 102. Advanced placement and credit is given for a score of 4 or 5 on the AP tests. Alternatively, students may take the departmental advanced placement examinations just prior to or during the first week of classes. Entering students are strongly urged to take departmental placement examinations in physics and mathematics if they had reasonably strong courses in high school. It is best for a student considering a physics major to complete the introductory requirements in the first year. However, the major sequence is designed such that a student who completes the introductory sequence by the end of the sophomore year can major in physics.

Major Requirements

Beyond the four introductory physics and mathematics courses, nine additional courses are required for the major. (Haverford courses may be substituted for Bryn Mawr courses where appropriate.) Five of the nine courses are Physics 206, 214, 215, 306 and Mathematics 201. The remaining four courses must be chosen from among the 300-level physics courses, any one course from among Astronomy 305, 320 and 322, or any one course from among Mathematics 303, 312 and 322.

The department has been very successful in preparing students for graduate school in physics, physical chemistry, materials science, engineering and related fields. To be well prepared for graduate school, students should take Physics 302, 303, 308, 309 and 331. These students should also take any additional physics, mathematics and chemistry courses that reflect their interests, and should engage in research with a member of the faculty by taking Physics 403. Note that Physics 403 does not count toward one of the 13 courses required for the major.

Typical plans for a four-year major in physics are listed below.

Four-Year Plan meeting the minimum requirements for the major:

1st Year
Physics 103, 104
Mathematics 101, 102

2nd Year
Physics 214, 215, 206
Mathematics 201

3rd Year
Physics 306 and one (or two) other 300-level physics course(s)

4th Year
Three (or two) other 300-level physics courses

Four-Year Plan providing adequate preparation for graduate school:

1st Year
Physics 103, 104
Mathematics 101, 102

2nd Year
Physics 214, 215, 206
Mathematics 201

3rd Year
Physics 306 and either 303, 309 or 308, 302

4th Year
Physics 331 and either 308, 302 or 303, 309
Physics 403

The physics program at Bryn Mawr allows for a student to major in physics even if the introductory courses are not completed until the end of the sophomore year, as long as calculus is taken in the first year. It is also possible, although difficult, for the student majoring in three years to be adequately prepared for graduate school. To do this, the outline below should be supplemented with (at least) Physics 403 in the 4th year.

Three-Year Plan meeting the minimum requirements for the major:

1st Year
Mathematics 101, 102

2nd Year
Physics 103, 104, 206
Mathematics 201

3rd Year
Physics 214, 215, 306 and 302 or 331

4th Year
Three 300-level physics courses

Honors

The A.B. degree may be awarded with honors in physics. The award is based on the quality of original research done by the student and a minimum grade point average. The research must be described in a senior thesis presented to the department. A grade point average of 3.4 or higher in 200- and 300-level physics courses (excluding Physics 380 and 390) and an overall grade point average of at least 3.0, both calculated at the end of the senior year, must be achieved.

Minor Requirements

The requirements for the minor, beyond the introductory sequence, are Physics 206, 214, 215, 306; Mathematics 201; and two additional 300-level physics courses.

Minor in Computational Methods

Students may major in physics and receive a minor in computational methods. Students would need to complete the requirements for the Physics major including two of the following courses: Physics 305 (or 316 at Haverford), 306 and 322. Further, students would have to complete Computer Science 110, 206 and 231 and one of Computer Science 212, 225 (at Haverford), 245, 246, 330 or 340 (at Haverford).

Minor in Educational Studies or Secondary-School Teacher Certification

Students majoring in physics may pursue a minor in educational studies or state certification to teach at the secondary-school level. Students seeking the minor need to complete the requirements for the physics major including one of Physics 380, 459 (at Haverford) or 460 (at Haverford), and five additional courses in the Education Program, including a two-semester senior seminar, which requires five to eight hours per week of fieldwork. To earn secondary-school certification (grades 7-12) in physics students must: complete the physics major plus two semesters of chemistry and one semester as a teaching assistant in a laboratory for introductory or intermediate physics courses; complete one year of biology (recommended); complete six education courses; and student-teach full-time (for two course credits) second semester of their senior year.

A.B./M.A. Program

To earn an M.A. degree in physics in the College’s A.B./M.A. program, a student must complete the requirements for an undergraduate physics major and also must complete six units of graduate level work in physics. Of these six units, as many as two units may be undergraduate courses at the 300 level taken for graduate credit (these same two courses may be used to fulfill the major requirements for the A.B. degree), at least two units must be graduate seminars at the 500 level, and two units must be graduate research at the 700 level leading to the submission and oral defense of an acceptable M.A. thesis. Students must also demonstrate skill in computing or in a foreign language.

Courses at Haverford College

Many upper-level physics courses are taught at Haverford and Bryn Mawr in alternate years. These courses (numbered 302, 303, 308, 309 and 322) may be taken interchangeably to satisfy major requirements.
