In the College of Arts and Sciences .
The concepts and methods of physics have an impact on nearly all areas of human endeavor. Thus, the Department of Physics offers courses in physics for the entire Cornell community. There are general education courses for nonscientists, well-designed introductory sequences for science and engineering majors, more advanced courses for physics majors, and rigorous programs of graduate study, up to doctoral-level independent research.
Undergraduate and graduate students benefit from an outstanding faculty and world-class research facilities in the Laboratory of Atomic and Solid State Physics (LASSP) and the Laboratory of Elementary Particle Physics (LEPP). Physics faculty members and students conduct research in condensed-matter physics, nanophysics, biophysics, atomic physics, X-ray physics, high-energy particle physics, accelerator physics, and astrophysics. Students are invited to attend weekly research seminars and colloquia that showcase the work of the national and international physics communities. Undergraduates are encouraged to participate in research, and many find summer employment within the department.

Courses for Non-Physics Majors:
Students may obtain advanced placement and credit, as outlined in “Advanced Placement of Freshmen,” and transfer credit for physics courses taken elsewhere. Students seeking transfer credit should read the instructions at www.physics.cornell.edu/undergraduate/obtaining-transfer. Students seeking advice on the use of AP credit should consult with the director of undergraduate studies.
The Physics Major: Two Routes to a Promising Future:
The analytical and problem-solving skills and the fundamental conceptual and practical understanding of how the world works provided by an education in physics have allowed physics majors to pursue careers—and have major impacts—not just in physics, but in engineering, education, medicine and the life sciences, the military services, computer and information sciences, earth and environmental sciences, law, finance and economics, management consulting, philosophy of science, forensics, and public policy. Reflecting this breadth of opportunity, the Physics Department offers two approaches to the major:
- The concentration within physics is the principal path to professional or graduate work in physics and closely related fields, and is also the best choice for students who wish to obtain maximum benefit from rigorous studies in physics. The inside concentration consists of the core physics courses plus electives taken within the Physics Department.
- The concentration outside physics provides more flexibility for those want to develop skills in physics but whose career interests lie elsewhere. For example, a premedical or biophysics student may concentrate in biology; a pre-law student may concentrate in business, history, or public policy; and a student planning graduate work in econometrics or on pursuing an M.B.A. may concentrate in economics. Students interested in education careers (and in capitalizing on the critical national shortage of high school physics teachers) may concentrate in education, allowing them to complete a master’s degree in physics education with New York State Teacher certification in one additional year at Cornell.
Physics majors—especially those concentrating within physics—are advised to start the introductory physics sequence in the first semester of their freshman year, as a delayed start reduces flexibility in future course scheduling. Students who switch to the physics major after taking introductory physics in their sophomore year can usually still complete an outside concentration. Students may apply to join the physics major after completing two full semesters of physics courses at Cornell, together with the appropriate mathematics prerequisites. In order to join the major, students must have at least a grade of B- in two of their Cornell physics courses, and have no physics grades lower than C-. Propsective physics majors with any physics grades lower than B- should as soon as possible meet with the director of undergraduate studies to discuss their preparation. Grades of at least C- (or S for S-U only courses) are required in all courses counting toward the physics major.
Prospective majors are urged to meet with the Physics director of undergraduate studies for advice on advanced placement credit and on program planning. Based on their specific interests, students will be matched with a major advisor by the director of undergraduate studies. The student and major advisor will then work out the details of the major course program.
Courses for Physics Majors:
The Physics Core—All physics majors must complete a core of physics and mathematics courses, as follows:
A three-semester introductory physics sequence:
Or its more analytic “honors” version:
PHYS 2207 students with life/chemical/health science interests who decide to switch to the physics major may complete:
A transition from PHYS 2208 to PHYS 2214 is also possible for students with very strong math backgrounds.
Mathematics courses covering single and multivariable calculus, linear algebra, series representations, and complex analysis:
Inside concentrators should complete at least one additional year of applicable mathematics such as AEP 4210 and AEP 4220 .
Five upper-level courses beyond the three-semester introductory sequence, consisting of:
(1) The two-course sequence in modern physics:
(2) At least three semester hours of laboratory work selected from:
(3) An intermediate course in classical mechanics:
(4) An intermediate course in electromagnetism:
In addition to the core, each physics major must complete at least 15 semester hours of credit in an area of concentration that has been agreed upon by the student and major faculty advisor consistent with the following guidelines.
Concentration within Physics:
Students planning professional or graduate work in physics are encouraged to take the more advanced and analytically rigorous versions of the core courses—PHYS 1116 , PHYS 2217 , PHYS 2218 , PHYS 3318 , and PHYS 3327 . Students with weaker high school preparation may start in PHYS 1112 and then switch to the advanced sequence in later semesters. The best-prepared students, who may qualify for advanced placement credit for PHYS 1112 and/or PHYS 2213 , are still strongly encouraged to start with PHYS 1116 .
For a concentration within physics, the minimum 15 hours beyond the core must be composed of physics courses with numbers greater than 3000 or other courses approved by the director of undergraduate studies (for example, ASTRO 3332 , ASTRO 4431 –ASTRO 4432 , or AEP 4340 ). These 15 hours must include the senior laboratory course PHYS 4410 in addition to one of the lab courses listed for the core, so that a physics concentration requires a minimum of 7 credit hours of laboratory work. The accompanying table shows some typical course sequences that fulfill the major requirements. The sequence followed by each student will depend upon his or her interests and precollege preparation, and will be determined in consultation with the major advisor. Students are advised to strongly consider taking PHYS 3341 and PHYS 4443 . Majors are strongly encouraged to participate in the department’s research activities. If this activity is done as an independent project, PHYS 4490 , up to 8 credit hours can be applied toward the concentration.
Concentration outside of Physics:
For outside concentrations, the courses to be counted in the minimum 15 credit hours beyond the core must have internal coherence and lead to mastery in the area of concentration. The course sequence must be worked out with and approved by the major faculty advisor. At least 8 of the 15 credit hours must be in courses numbered above 3000. Past areas of concentration include astronomy, business, chemical physics, computer science, econometrics, education, geophysics, history, and philosophy of science, law, meteorology, and public policy. A combined biology/chemistry concentration is common for premedical students or those who wish to prepare for work in biophysics.
The department particularly wishes to encourage students with an interest in science education. Physics majors can obtain teaching certification by concentrating in education and then completing a one-year master of arts in teaching (M.A.T.) degree. Information about the education concentration and M.A.T. can be obtained from the Department of Education’s Cornell Teacher Education Program, from the physics department’s Teacher in Residence, or from the Physics director of undergraduate studies.
The core for students with outside concentrations may follow either PHYS 1112 –PHYS 2213 –PHYS 2214 , PHYS 3314 , and PHYS 3323 or the advanced PHYS 1116 –PHYS 2217 –PHYS 2218 , PHYS 3318 , and PHYS 3327 . Students concentrating in astronomy who might continue on to graduate school in that field are encouraged to include ASTRO 4410 , ASTRO 4431 , and ASTRO 4432 within the concentration.
A student may be granted honors in physics upon the recommendation of the Physics Advisors Committee of the physics faculty. There is no particular course structure or thesis requirement for honors.
Students are welcome to pursue a physics major concurrently with another major; either in the college of Arts and Sciences or in another college through the dual-degree program. Any course used to satisfy a requirement of another major may be used in satisfaction of physics major requirements only if the student’s concentration is within physics.
