Natural Sciences: Physics, 2012-2013
The physics curriculum introduces students to concepts and methods that are fundamental throughout the sciences. It provides opportunities for first-hand experimental and theoretical investigations, together with the study of those basic principles that have led to profound scientific, philosophical and technological developments.
Prospective majors in all of the science disciplines are advised to study some physics in their freshman or sophomore year, because all contemporary sciences rely heavily on basic physical principles. There are three different introductory options. PHYS 101 and 102 constitute a year-long, self-contained treatment of all of physics, with particular attention to applications in the life sciences. PHYS 105 and 106 use calculus somewhat more intensively and are designed for students who expect to continue their study of physics in other courses, either in the physics or the chemistry department. PHYS 115 (followed by 106) provides a third option, designed for students with advanced preparation. Advice on course selection is provided on the department’s web site. The department also offers a half-credit course, ASTR/PHYS 152, intended for first-year students who are considering a physical science major and who would like an opportunity to study recent developments in astrophysics.
The department offers several courses that can be taken with no prerequisites or prior experience in physics. Currently, there are three courses that fall into this category: PHYS 112 examines the conceptual difficulties of quantum mechanics; PHYS 111 considers the science behind various sustainable energy options and the means by which scientists influence policy; and PHYS 108 covers applications of the physical sciences to modern medicine.
Physics offers three distinct programs: a traditional major, an interdisciplinary major designed for a broader audience and a minor. The requirements for these three options are listed below.
A typical course sequence introducing both the traditional major and the minor consists of PHYS 105 (or 115), 106, 213, 214 and the PHYS 211 and 212 laboratories. However, students beginning their study in PHYS 101 and 102 may continue with PHYS 213 and join the major or minor as well. PHYS 105 (or 115), 106, 213 and 214 are also prerequisites for the astronomy and astrophysics majors; ASTR/PHYS 152 is highly recommended, but not required.
The remainder of the traditional major program is quite flexible and, with an appropriate selection of upper-level courses, can accommodate students whose interests extend beyond physics to the interdisciplinary fields of astrophysics, biophysics, chemical physics, philosophy of science, biomedical science or engineering.
The department emphasizes student participation in research with faculty members. Currently, we have active research programs in quantum gravity and theoretical cosmology, quantum computing, observational cosmology, nonlinear physics and fluid dynamics, extragalactic astronomy, biophysics, and nanoscience. Courses numbered 412 to 417 provide majors with opportunities to participate in these research efforts for academic credit during their senior year. Paid summer research positions are often available.
In the Senior Seminar (PHYS 399), majors learn about the wide range of careers related to physics, and prepare a colloquium and senior paper based on independent work. Advanced students interested in teaching may participate in the instructional program by registering for PHYS 459 or 460. Physics majors may also take an area of concentration in education; see the section on Education and Educational Studies. (Students interested in physics or science education at the secondary level should also consult the teaching certification information in the section on Education and Educational Studies.)
Concentrations in both computer science and scientific computing are available for physics majors. Both of these programs are described under the Computer Science program. The department coordinator for both of these concentrations is Peter Love. Physics majors with biological interests may also qualify for the biophysics concentration, described under Biochemistry and Biophysics.
Students interested in engineering can complete an individualized major program in preparation for graduate work in engineering or the Engineering 4/1 Program with the University of Pennsylvania or the 3/2 Program with Caltech. Detailed information is available from the coordinator, Walter Smith. Students interested in materials science should also consult the related offerings in materials chemistry through Haverford’s chemistry department.

- PHYS 105 (or 101 or 115), 106 (or 102), 213, 214, 211 and 212 (or Bryn Mawr equivalents). The last two may be taken concurrently with PHYS 213 and 214.
- MATH 121 and 204 or Bryn Mawr equivalent. For students who are contemplating advanced work in mathematics, PHYS 216 can replace 121, and PHYS 215 can replace 204.
- Six upper-level courses in physics at Haverford or Bryn Mawr. One of these must be a laboratory course such as PHYS 316 or 326. All majors must take three of the four core theoretical courses: PHYS 302, 303, 308 and 309. Students considering graduate study in physics should take four of the following five courses by the end of their junior year: PHYS 302, 303, 308, 309 and 316 or 326 (or their Bryn Mawr equivalents). TTwo of the six upper-level courses may be replaced by upper-level courses in a related department, with the approval of the major advisor. (The student will be asked to prepare a brief written statement explaining the relationship between the proposed courses and the physics major.) One of the six upper-level physics courses may be a 400-level research course. Either PHYS 459 or 460 may also be counted among the six upper-level courses.
- The department requires one course outside the department at a level consistent with the student's background in astronomy, biology, computer science, chemistry or engineering (at Penn or Swarthmore). (This requirement is waived for double majors.)
- PHYS 399, including a thesis and colloquium based on independent work, and attendance at senior colloquia and distinguished lectures hosted by the department.
Students with multiple academic interests who are not likely to undertake physics graduate study are invited to consider the Interdisciplinary Physics Major, whose slightly abbreviated set of requirements can be completed in three years. This track, which can also facilitate a concentration, an engineering option or a minor in another department, can be discussed with any member of the Department. The requirements are as follows:
- Either PHYS 105 (or 115) and 106, or PHYS 101 and 102.
- PHYS 213, 214 and 211 (our sophomore lecture course sequence and one sophomore-level laboratory course).
- MATH 121 (or 216) and MATH 204 (or 215).
- Three 300-level physics lecture courses, of which two are drawn from this list of core courses: PHYS 302, 303, 308, 309.
- An upper-level laboratory course in the natural or applied sciences, such as PHYS 212, BIOL 300a or b, or CHEM 301 or 302. (Alternately, the student can request the substitution of an advanced laboratory course in another area of science or applied science.)
- Two other courses at the 200-level or higher in a related field that are part of a coherent program to be proposed by the student and approved by the major advisor.
- Senior Seminar (PHYS 399) and the associated senior talk and thesis.
The interdisciplinary major differs from the traditional physics major by offering more flexible course choices and by coordinating the physics courses with the student’s work in another field. In the version requiring the fewest physics courses, this major requires 8.5 instead of 10 physics courses, while both majors require 2 mathematics courses, and 3 courses in a related field.
- PHYS 105 (or 101 or 115) and PHYS 106 (or 102); 213, 214, 211 and 212 labs (or Bryn Mawr equivalents).
- MATH 121 and 204 or Bryn Mawr equivalent. For students who are contemplating advanced work in mathematics, MATH 216 can replace 121 and MATH 215 can replace 204.
- One of the four “core” 300-level lecture courses in physics at Haverford or Bryn Mawr: PHYS 302 (Advanced Quantum Mechanics), 303 (Statistical Physics), 308 (Advanced Classical Mechanics) or 309 (Advanced Electromagnetism and Modern Optics).
- Participation for two semesters in the public lectures and seminars hosted by the department.
The award of Honors in physics is based upon the quality of performance in course-work and the senior colloquium and paper. High Honors carries the additional requirement of demonstrated originality in senior research.
