Undergraduate Major

A typical scenario for a physical explanation of a given situation is this: a small collection of basic physical principles relevant to the situation is used to create a mathematical model of it; computations are carried out using the model, leading to predictions that are checked experimentally; if there is agreement, the physical situation is deemed to have been explained. The objective of the program in physics is to make it possible for students to execute such a scenario for a wide range of physical situations. To that end, students are required to attain a firm grasp of the basic principles of classical physics and familiarity with those of quantum physics, to learn how to decide which principles are relevant to a given situation and how to construct the appropriate mathematical model, to develop the mathematical skills necessary to carry out the computations that generate predictions, and to strengthen the experimental skills used in exploring new phenomena and in carrying out the verification step of the typical scenario.

The ability to execute the typical scenario of physical explanation is useful not only to research physicists, but also to scientists in many other fields, especially interdisciplinary ones, such as biophysics and environmental science; it is also useful to engineers, to members of the medical profession, and to architects. For that reason, the physics program has made special arrangements to integrate a physics major with study preparing for a career in any of the areas mentioned above. Students interested in combining biology and physics should see the interdepartmental program in biological physics elsewhere in this Bulletin.

Graduate Program in Physics

The graduate program in physics is designed to equip students with a broad understanding of major fields of physics and to train them to carry out independent, original research. This objective is to be attained by formal course work and supervised research projects. As the number of students who are accepted is limited, a close contact between students and faculty is maintained, permitting close supervision and guidance of each student.

Advanced degrees will be granted upon evidence of the student's knowledge, understanding, and proficiency in classical and modern physics. The satisfactory completion of advanced courses will constitute partial fulfillment of these requirements. Research upon which theses may be based, with residence at Brandeis, may be carried out in the following areas:

1. Theoretical Physics
   Quantum theory of fields; relativity; supergravity; string theory; condensed matter theory; statistical mechanics; biological physics.
2. Experimental Physics
   High-energy experimental physics; condensed matter physics; astrophysics; and biological physics.

Every graduate teaching assistant (TA) is supervised by a member of the faculty, who serves as a mentor to improve the quality of the TA's teaching. In recognition of this objective, each year the physics department awards the David Falkoff Prize to an outstanding teaching assistant. An additional goal of the department is to enable graduate students to be able to present their research findings in a clear and effective manner. Each spring the department organizes the Stephan Berko Symposium, where students give short presentations of their research. These talks are prepared with the assistance of faculty research advisers. The best graduate student research project and the best undergraduate research project are recognized with Stephan Berko Prizes.

Undergraduate Major

The Brandeis physics major offers students a unique opportunity to prepare for graduate school or employment in a variety of technical fields. Our undergraduate program is strongly based on a first-rate research program by our faculty, which gives students the opportunity to participate in cutting-edge research in areas including astrophysics and cosmology, biological physics, condensed matter physics, high-energy particle physics, and theoretical physics, and topics such as string theory, liquid crystals, DNA, polymers, elementary particles, distant quasars, and the early universe.

Core Skills

After completing the major, students will:

1. Be able to formulate hypotheses for the physical principles behind observed phenomena. Be able to construct mathematical models embodying these hypotheses, such that the models are consistent with existing data and make testable predictions for further experiments.

2. Be able to evaluate measurement errors in scientific data sets and the effects of these errors on the interpretation of the data; and be able to calculate levels of confidence in conclusions drawn from the data.

3. Be able to explain to a general audience the physical principles that underlie our understanding of nature.

4. Know how to design experiments, computer simulations, and/or theory to test a scientific hypothesis.

5. Have developed their skills in applied mathematics, in laboratory techniques, and in oral and written presentation.

Knowledge

After completing this major, students will have learned at an advanced undergraduate level: Newton’s laws (mechanics), Maxwell's equations (electricity and magnetism), special relativity, statistical mechanics, thermodynamics, quantum mechanics, optics, statistics, and error analysis.

Upon Graduation

Most of our graduates go on to graduate school, while some go into high-tech employment, medical school, or other professional studies. Our students have an excellent record of entering the best graduate programs.

Because the sequence in which physics courses should be taken is tightly structured, and in most cases requires at least three years to complete, students contemplating a major in physics should consult the physics undergraduate advising coordinator at the first opportunity. For most students, such consultation should take place before enrolling in courses at the beginning of the first year. PHYS 11a or 15a and 19a should normally be part of the first-semester program. Midyear students entering Brandeis in January need to consult the physics undergraduate advising head the summer before they enroll at Brandeis.

The general requirements for admission to the Graduate School, given in an earlier section of this Bulletin, apply to candidates for admission to the graduate area in physics. Admission to advanced courses in physics will be granted following a conference with the student at entrance.

Six semester courses in physics at the level of PHYS 10 or above. Note that PHYS 18a,b and PHYS 19a,b count as one semester courses.

No grade below a C- will be given credit toward the minor and no course taken pass/fail may count toward the minor requirements.

Degree of Bachelor of Arts

The Bachelor of Arts degree is intended for students who are not intending to pursue graduate studies in physics. For example, the student might desire to pursue science journalism, the history or philosophy of science, patent law, economics, business, pre-medical studies, or K-12 science education. Thus, the B.A. degree combines a solid grounding in physics combined with a topical focus designed by the student in conjunction with the student's major advisor. There are 12 total courses required for the major:

1. PHYS 10a,b, 11a,b or 15a,b (11a,b or 15a,b being strongly recommended).
2. PHYS 20a.
3. PHYS 31a.
4. PHYS 40a.
5. PHYS 30a OR PHYS 100a.
6. Two semesters of laboratory courses in Physics; a year of PHYS 18a,b or 19a,b counts as one semester towards this requirement.
7. One semester of mathematics numbered higher than first-year calculus (MATH 10a b).
8. Three additional courses, at least one of which is a physics course numbered higher than 20, designed around some topical focus, chosen in consultation with (and subject to approval by) the student's major advisor.
9. Foundational Literacies: As part of completing the Physics major, students must:

   • Fulfill the writing intensive requirement by successfully completing one of the following: PHYS 39a or PHYS 99d.

   • Fulfill the oral communication requirement by successfully completing one of the following: PHYS 99d.

   • Fulfill the digital literacy requirement by successfully completing one of the following: PHYS 19a or PHYS 19b.

10. No course with a grade of below C- can be used to satisfy the requirements of the major.
11. No course taken pass/fail may count toward the major requirements.
    
    A few examples of some possible topical groupings are:

    1. Philosophy of science: PHYS 102a (General Relativity); PHIL 35a (Philosophy of Science); PHIL 144a (Philosophical Problems of Space and Time).

    2. Science Policy: whichever of PHYS 30a and 100a the student has not already taken to satisfy requirement (E) above; POL 174b (Problems of National Security). An alternate set of courses might be: PHYS 31b (quantum mechanics), POL 174b, ECON 141b (Economics of Innovation).

    3. Science journalism: PHYS 107b (Particle Physics) or 108b (Astrophysics); JOUR 130b (Science and Journalism in Society); JOUR 109b (Digital and Multimedia Journalism).

Degree of Bachelor of Science

This degree provides the rigorous training needed for students intending to pursue graduate work in physics or engineering. There are 17 total courses required for the major:

1. PHYS 11a,b or PHYS 15a,b.

2. PHYS 20a.

3. PHYS 31a,b.

4. PHYS 30a.

5. PHYS 40a.

6. Three semesters of laboratory courses in Physics; a year of PHYS 19a,b counts as one semester towards this requirement.

7. Three additional courses in Physics, two of which must be numbered 20 or above.

8. Either MATH 15a and 20a, or MATH 22a,b.

9. Two additional upper-level courses in the School of Science excluding Physics courses: Math courses numbered above 22; Computer Science courses numbered above 20; or any other courses approved by the department. Physics courses may not be used to fulfill this requirement, even those that are cross-listed in another department. Courses from other departments that are cross-listed with Physics are eligible.

10. Foundational Literacies: As part of completing the Physics major, students must:

    • Fulfill the writing intensive requirement by successfully completing one of the following: PHYS 39a or PHYS 99d.

    • Fulfill the oral communication requirement by successfully completing one of the following: PHYS 39a or PHYS 99d.

    • Fulfill the digital literacy requirement by successfully completing one of the following: PHYS 19a or PHYS 19b.

11. No course with a grade of below C- can be used to satisfy the requirements of the major.

12. No course taken pass/fail may count toward the major requirements.

There are several natural tracks through the undergraduate physics courses. The first is: Year 1—PHYS 11a,b or 15a,b, PHYS 19a,b, MATH 10a,b or Math 15a and Math20a, or Math 22ab; Year 2—PHYS 20a, PHYS 31a, PHYS 29a, or MATH 15a and 20a, or MATH 22a,b; Year 3—PHYS 30a, 31b, PHYS 39a, PHYS 40a; Year 4—Electives; PHYS 100a is strongly recommended for all majors.

The second, a premedical track, is: Year 1—PHYS 11a,b or 15a,b, PHYS 19a,b, MATH 10a,b; Year 2—PHYS 20a, PHYS 31a, CHEM 11a,b, 18a,b; Year 3—BIOL 22ab, BIOL 18a,b, CHEM 25a,b, 29a; Year 4—PHYS 29a, PHYS 30a, 31b. Note that while the requirements for the BA and BS degrees in physics are not changed for pre-medical students, as many as two suitable upper-level science courses outside of physics may be substituted for physics courses with the permission of the undergraduate advising coordinator. Students should consult the premedical advisors before deciding on a program.

Students are encouraged to construct other tracks that might better suit their needs in consultation with their advisers.

Students considering a career in engineering should consult the description of the Columbia University School of Engineering Combined Degree Program in the special academic opportunities section of this Bulletin.

A student intending to pursue graduate work in physics will normally add to the tracks above courses selected from elective such as PHYS 39a, 100a, 102a, 103a, 104a, 105a, 108b and 110a, or graduate courses dealing with previously treated subjects at a more advanced level, such as PHYS 161a,b and 162a,b. Normally only some of the physics elective courses will be offered in a given year; the others will normally be offered in the following year. Undergraduates are not permitted to enroll in physics courses numbered above 160 without the explicit approval of their appropriate major advisers.

A student who has attained a grade of 4 or 5 on the Advanced Placement Examination Physics B may obtain credit for PHYS 10a,b; a student who has attained a grade of 4 or 5 on the Advanced Placement Examination C: Mechanical may obtain credit for PHYS 11a while a grade of 4 or 5 on Advanced Placement Examination Physics C: Electrical may earn credit for PHYS 11b. A student who claims any of these advanced placement credits may not take the same or equivalent courses for credit: PHYS 10a,b, or PHYS 11a,b. If a student wishes to claim AP credit AND take PHYS 15a,b, (recommended for many students with AP credit) then the AP credit earns course credit (towards the 128 total credits degree requirement) but does not count towards the physics major. PHYS 15 earns both course credit and counts toward the physics major.

In order to be a candidate for a degree with distinction in physics, majors must successfully complete and receive a grade of B- or higher in a departmentally approved honors program of either PHYS 99d or two semester courses in physics numbered 161, 162, or 163. Students must have their honors programs approved by the departmental advising coordinator before the beginning of their penultimate semester.

Normally, first-year graduate students will elect courses from the 100 series, with at least four courses numbered above 160. The required first-year courses are PHYS 161a, 162a,b, and 163a. Students are required to take either 161b or 163b in the first or second year. A laboratory course, PHYS 169b or QBIO 120b, and CONT 300b (Responsible Conduct of Science) or the comparable Division of Science Responsible Conduct of Research (RCR) workshop are also required, in the first or second year. To obtain credit toward residence for a graduate course taken at Brandeis, a student must achieve a final grade of B- or better in that course. Students may obtain credit for advanced courses taken at another institution, provided their level corresponds to the level of graduate courses at Brandeis and that an honor grade in those courses was obtained. To place out of any of the PHYS 161, 162, or 163 sequences, a student must pass an exemption exam before the end of the second week of the course.

Residence Requirement

For those accepted for full-time study, there is a one-year residency requirement. No transfer residence credit will be allowed toward the fulfillment of the Master's requirements. The program may take an additional one or two semesters to complete as an Extended Master's student. Part-time students have no residency requirement.

Course Requirements

Eight semester courses in physics numbered above 160. A Master's thesis on an approved topic may be accepted in place of a semester course. The Master's thesis must be deposited electronically to the Robert D. Farber University Archives at Brandeis.

Language Requirement

There is no foreign language requirement for advanced degrees in physics.

Qualifying Examination

Satisfactory performance in the qualifying examination is required. The qualifying examination consists of a written and an oral part and both parts are administered during the first year of the program. The written part of the qualifying examination is the final examinations in PHYS 161a, 162a,b, and 163a, unless these courses have been exempted by separate examination, or credit has been given for equivalent courses taken elsewhere. There are two oral exams on general physics; the first at college physics level, the second at the first-year graduate level.

All of the requirements for the master's degree as well as the following:

Residence Requirement

The minimum residence requirement is three years. A student may obtain up to one year's residence credit toward the PhD requirements for graduate studies taken at another institution.

Teaching Requirement

It is required that all PhD candidates participate in undergraduate teaching during the course of their studies.

Course Requirements

In addition to the general requirements for advanced degree candidates, each student must also take two elective advanced physics courses, one of which is outside the student’s intended area of research. These must be chosen in consultation and with the approval of the graduate advisor. A total of at least nine semester courses in physics numbered above 160 are required for the doctoral degree.

Each summer, full-time PhD students are required to do work related to their research area under the supervision of a faculty member. The work can take the form of dissertation research, or can involve an industrial internship. Students doing dissertation research over the summer should register for CONT 250. Students doing an industrial internship must have the consent of their advisor and should register for PHYS 393g.

Qualifying Examination

PHYS 161a, 162a,b and 163a with grades of B or above, in addition to the requirements listed for the master's degree.

Advanced Examinations

Advanced examinations are in topics partitioned in the several areas of research interest of the faculty. Faculty members working in each general area function as a committee for this purpose and provide information about their work through informal discussions and seminars. The advanced examination requirement consists of a written paper and an oral examination. Although no original research by the student is required, it is hoped that a proposal for a possible thesis topic will emerge. It is expected that the candidates will take the advanced examination in the field they wish to pursue for the PhD thesis by the beginning of the fourth term in order to qualify for continued departmental support beyond the second year.

Thesis Research

After passing the advanced examination, the student begins work with an adviser, who guides his or her research program. The adviser should be a member of the Brandeis faculty but in special circumstances may be a scientist associated with another research institution. The graduate committee of the physics faculty will appoint a dissertation committee to supervise the student's research. The student's dissertation adviser will be the chair of the dissertation committee.

Dissertation and Final Oral Examination

The doctoral dissertation must represent research of a standard acceptable to the faculty committee appointed for each PhD candidate. The final oral examination, or defense, is an examination in which the student will be asked questions pertaining to the dissertation research.

Requirements for the Degree of Doctor of Philosophy in Physics with Specialization in Quantitative Biology

Program of Study

Students wishing to obtain the specialization must first gain approval of the graduate program chair. This should be done as early as possible, ideally during the first year of graduate studies. In order to receive the PhD in physics with additional specialization in quantitative biology, candidates must complete (a) the requirements for the PhD described above and (b) the course requirements for the quantitative biology specialization that are described in the quantitative biology section of this Bulletin.

Any alteration to the quantitative biology course requirements must be approved by the graduate program chair and by the quantitative biology program faculty advisory committee.
