Physics
Smith College physics provides integrated, hands-on learning, supportive professors and fellow physics majors, real research projects and great physics toys.
The physics department offers a rigorous curriculum that pairs innovative teaching techniques with a supportive and close-knit community of faculty, staff and students. Students often double major with astronomy, computer science, math, engineering, chemistry and architecture. You can carry out leading-edge research on your own or in collaboration with faculty starting your first year. Faculty research interests include nonlinear optics, experimental and computational condensed matter physics, complex fluids, molecular materials, low-dimensional systems, cold atom physics and cosmology.
Requirements & Courses
Goals for Majors in Physics
Smith College physics majors graduate with a combination of disciplinary knowledge and skills that prepares them for graduate work in physics or other STEM fields, medical school, teaching, science policy and a variety of other career options.
The primary areas of knowledge covered by our major are mechanics, electricity and magnetism, quantum mechanics and thermal physics. Students will gain a good introductory knowledge of electronics, special relativity, optics, fluids and error analysis. In addition to these physical topics, our students need to master a variety of mathematical topics required in these fields.
At least as important as disciplinary knowledge are the skills required for a degree in physics. These include (but are not limited to) the following:
- Good problem-solving technique, including identification of physical principles, good use of diagrams, clear mathematical derivations, proper use of units, and physical analysis and assessment of results.
- Ability to convey knowledge and observations in both oral and written forms.
- Use of computer-based numerical and analytical methods to solve complex physical problems.
- Gain insight through the use of experimental design, instrumentation and methods that reveal signal and reduce noise in messy data.
- Reproducible data analysis, including the use of software for graphing, curve fitting, and basic statistical analysis to draw conclusions and infer significance.
The Education Track
Students who choose the education track in the physics major may learn some topics at a more introductory level in some areas than it would be for a regular major, but they should still gain facility with all of the topics listed above, except, in some cases, thermal physics. They should also get a good working knowledge of the main ideas to emerge from physics education research. They should become proficient in all the skills listed above as well as tutoring and providing in-class help to students.
Entering students planning to major in physics should take either PHY 117 or PHY 119 in the first year along with one or more courses in the Calculus I, Calculus II, Calculus III mathematics sequence, as appropriate. Students entering with a particularly strong background in physics should confer with a member of the department about the most appropriate course for them in this sequence.

Additional Programmatic Information
Director: Gary Felder
gfelder@smith.edu
Students can apply to complete honors, which involves working on an independent thesis project with one of the faculty members of the department. The completion of the thesis work will lead to a bachelor of arts degree with a notation of "Honors," "High Honors" or "Highest Honors." Look for information about how to apply, the timelines, dates and eligibility on the class deans website.
For the physics department, the eligibility criterion are as follows: GPA: π outside the major and 1.1π in the major
Honors in Your Senior Year
If you would like to do a thesis project in your senior year, talk to the faculty in the department to find out about their research and get an early start. Although not absolutely essential, it helps to get a head start with semester/summer projects with the faculty. Once you and your faculty project adviser have discussed and agreed to this, you have to wait to apply to enter departmental honors at the start of your senior year. The application deadline is within the first week of classes. Give the proposal and application priority when you return to campus. Once your proposal is approved by your department or program and the Subcommittee on Honors and Independent Programs (SHIP), you will get automatically officially registered in the course. This usually happens during the third week of the semester in which you start your thesis.
Students with a 4 or 5 on the AP Physics C mechanics exam are eligible to place out of PHY 117 Introductory Physics I. Students with a 4 or 5 on the AP Physics C electricity and magnetism exam are eligible to place out of PHY 118 Introductory Physics II. Students with a 5, 6, or 7 on the International Baccalaureate (IB) Higher Level Exam or a score of A or B on the International Cambridge A-level exam are strongly encouraged to take PHY 119 Advanced Introductory Physics, which replaces both PHY 117 and PHY 118 for the physics major and also satisfies the PHY 117 requirement for Engineering. Students coming into Smith who have successfully completed a year or more of AP high school physics or equivalent but have not taken the AP, IB, or Cambridge exam should choose between PHY 117 or PHY 119 following a consultation with the instructors of PHY 117 and/or PHY 119. Members of the department are happy to discuss your particular situation further; students are encouraged to stop by with their questions during Conversations.
