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. Qualified seniors can take graduate courses. Students may complete an M.A. in the combined A.B./M.A. program.

Faculty

Peter A. Beckmann, Marion Reilly Professor (on leave semester I)
Mark Matlin, Senior Lecturer and Laboratory Coordinator
Elizabeth F. McCormack, Professor
David Nice, Visiting Assistant Professor
Michael W. Noel, Associate Professor and Chair
Michael B. Schulz, Assistant Professor

The courses in Physics emphasize the concepts and techniques that have led to our present way of modeling the world around us. They are designed to both relate the individual parts of physics to the whole and to treat the various subjects in depth. Opportunities exist for interdisciplinary work and for participation by qualified majors in research with members of the faculty and their graduate students.

Required Introductory Courses for the Major and Minor

The introductory courses required for the physics major and minor are PHYS 121 (called PHYS 103 in 2007-08) and PHYS 122 (or PHYS 101 and 102) and MATH 101 and MATH 102. Advanced placement and credit is given for a score of 4 or 5 on the AP tests and for a score of 5 or above on the IB examination. Alternatively, students may take the departmental advanced placement examination either during the summer before entering Bryn Mawr or just prior to, or during, the first week of classes. Entering students are strongly urged to take this examination in physics and the corresponding placement examination in mathematics if they have had reasonably strong courses in high school. Students can place out of either the first or the first two semesters of physics and mathematics.

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 two introductory physics courses and the two introductory mathematics courses, nine additional courses are required for the major. (Haverford courses may be substituted for Bryn Mawr courses where appropriate.) Six of the nine courses must be PHYS 201, 214, 306, 331 and MATH 201, 203. The remaining three courses must be chosen from among the other 300-level physics courses, one of which may be substituted with any one course from among ASTR 305, 320 and 322, or any one course from among MATH 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 PHYS 302, 303, 308, and 309 (in addition to PHYS 306 and 331 which are required for the major). 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 PHYS 403. (Note that PHYS 403 is usually two semesters and does not count toward one of the 13 courses required for the major.) Seniors can take graduate courses, usually Physics 501: Quantum Mechanics or Physics 503: Electromagnetism, to get a head start on graduate school.

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

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

1st Year
PHYS 121 (called PHYS 103 in 2007-08), 122
MATH 101, 102

2nd Year
PHYS 201, 214
MATH 201, 203

3rd Year
PHYS 306, 331 and one other 300-level physics course

4th Year
Two 300-level physics courses

Four-Year Plan providing adequate preparation for graduate school:

1st Year
PHYS 121 (called PHYS 103 in 2007-08), 122
MATH 101, 102

2nd Year
PHYS 121, 122
MATH 201, 203

3rd Year
PHYS 306, 331 and either 303, 309 or 308, 302

4th Year
PHYS 308, 302 or 303, 309
PHYS 403 (both semesters)

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 (MATH 101 and 102) 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) PHYS 403 for both semesters in the 4th year.

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

1st Year
MATH 101, 102

2nd Year
PHYS 103, 122
MATH 201, 203

3rd Year
PHYS 201, 214, 306, 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 PHYS 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 PHYS 201, 214, 306, 331; MATH 201, 203; and one additional 300-level physics course. The ASTR and MATH courses described under Major Requirements may not be substituted for the one additional 300-level physics course.

Minor in Computational Methods

Students can major in physics and receive a minor in computational methods. Students would need to complete the requirements for the physics major where one of the additional 300-level courses must be PHYS 322. Further, students would have to complete CMSC 110, 206 and 231 and one of PHYS 304 (at Haverford), CMSC 212, 225 (at Haverford), 245, 246, 330 or 340 (at Haverford).

Minor in Educational Studies or Secondary-School Teacher Certification

Students majoring in physics can pursue a minor in educational studies or state certification to teach at the secondary-school level. Students seeking the minor need to complete six education courses 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 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 as indicated in the listings of the specific courses below. These courses (numbered 302, 303, 308, 309, and 322) may be taken at either institution to satisfy major requirements. In addition 100- and 200-level courses can be used to replace 100- and 200-level courses at Bryn Mawr but these courses are not identical and careful planning is required.

PHYS B101, B102 Introductory Physics

Two introductory courses on the study of the physical universe intended primarily for students on the pre-health professions track. Emphasis is on developing an understanding of how we study the universe, the ideas that have arisen from that study, and on problem solving. Topics are taken from among Newtonian kinematics and dynamics, relativity, gravitation, fluid mechanics, waves and sound, electricity and magnetism, electrical circuits, light and optics, quantum mechanics, atomic and nuclear physics, and particle physics and cosmology. Calculus is introduced and used as needed. An effective and usable understanding of algebra and trigonometry is assumed. Freshmen who will take or place out of MATH 101 should take PHYS 121 (called PHYS 103 in 2007-08). Lecture three hours, laboratory three hours every second week. (staff, Division IIL and Quantitative Skills)

PHYS B103 An Introduction to Physics (2007-08)

See PHYS B121 for course description.

PHYS B107 Conceptual Physics

This course addresses how human beings model physical systems far from the everyday human realm. The course addresses how the human senses work, the role of biological evolution, and how we develop models for the physical universe. We try to understand that the "world out there," though an absolute in some abstract sense, must be interpreted and "modeled" by the human brain. Once this is understood, a huge pedagogical impediment to engaging models in electromagnetism, quantum mechanics, special relativity, general relativity, cosmology, particle physics, and nuclear physics is overcome. There is no mathematics at all. Readings include Abbott's Flatland, Wells' The Country of the Blind, Borges' Library of Babel, Kafka's Metamorphosis, other short stories involved with modeling the world, and select short scientific articles. Students keep a journal where they comment on web sites related to the topics covered in class. Lecture three hours, laboratory three hours every second week. Note: this course does not satisfy the Quantitative Skills requirement. Also see PHYS 150 which is PHYS 107 without the laboratory. (Beckmann, Division IIL) Not offered in 2007-08.

PHYS B109 How Things Work

This course gives students the opportunity to explore the physical principles that govern the objects and activities familiar in their everyday lives. For example, objects such a roller coasters, rockets, light bulbs and Xerographic copiers will be used to explore motion, fluids, heat and electricity. Lecture three hours, laboratory three hours every second week. Note: this course does not satisfy the Quantitative Skills requirement. Also see PHYS 160 which is PHYS 109 without the laboratory. (Noel, Division IIL)

PHYS B121 An Introduction to Physics

Called PHYS 103 for 2007-08. This course develops physical intuition and problem-solving skills by exploring ideas and discoveries of twentieth and twenty-first century physics. Fundamental physical concepts such as energy, momentum, waves, and electromagnetic forces are introduced and used to gain insight into topics such as the quantum mechanical behavior of atoms, the wave-particle duality of matter, special relativity, and cosmology. This course is the first semester of the introductory physics sequence, but it also serves as a one-semester stand-alone course. It is suitable for any student with a strong interest in physical science. Lecture three hours, laboratory three hours every second week. Corequisite: Math 101. (staff, Division IIL and Quantitative Skills)

PHYS B122 Classical and Relativistic Mechanics
