The Physics Department offers a program consisting of course studies in broad areas of classical and modern physics, and research studies in both experimental and theoretical physics.

The research activities of the faculty are focused primarily in high energy, elementary particle physics and related fields. The advanced classes are small, so there is ample opportunity for students to work closely with the Physics faculty, particularly in the advanced laboratories where students become familiar with state-of-the-art equipment. Undergraduate physics majors are strongly encouraged to participate in research activities. A majority of majors go on to pursue advanced degrees upon graduation from SMU.

Bachelor of Science Degree. This degree program is designed for students who plan careers in physics in industry, laboratories, or academia. A candidate for the B.S. degree must complete a minimum of 38 term hours in physics, including PHYS 1105*, 1106*, 1303, 1304 (or 1407 and 1408), 3305, 3344, 3345, 3374, 4211, 4392, 5382 and 5383. (PHYS 4321 may be substituted for 3345.) An additional laboratory course, PHYS 4112, is strongly recommended. Additional courses may be chosen from a variety of physics electives or in related fields with departmental permission. A candidate for the B.S. degree must also complete 15 term hours of courses in mathematics, including MATH 1337, 1338, 2339, 2343 and one advanced mathematics course. Students planning to pursue graduate studies are encouraged to complete more than the minimum 38 credit hours in physics and 15 credit hours in mathematics.

Bachelor of Arts Degree. This degree program is appropriate for students who wish to combine a physics curriculum with a broad liberal arts program with the aim of pursuing careers in medicine, teaching, business, and government. A candidate for the B.A. degree must complete a minimum of 30 term hours in physics, including PHYS 1105*, 1106*, 1303, 1304 (or 1407 and 1408), 3305, 3344, 4211, 4392, and 5382. Additional courses may be chosen from the available physics electives or in related fields with departmental permission. Additionally, a candidate for the B.A. degree must complete 15 term hours of courses in mathematics, including MATH 1337, 1338, 2339, 2343 and one advanced mathematics course.

Minor in Physics. A minor in physics is particularly appropriate for majors in the natural sciences, including pre-med, mathematics, and engineering. The departmental requirement for a minor in physics is 17 term hours in physics, including PHYS 1105*, 1106*, 1303, 1304, or 1407 and 1408, and nine hours of advanced course work.

The Departmental Distinction Program. A physics major achieving a B.S. degree may graduate "with departmental distinction" by successfully completing a special program of study in addition to the requirements stated above, while maintaining a minimum G.P.A. of 3.50. The special program consists of independent reading, research and senior thesis under the direction of a departmental faculty member. The student must apply to the Department for this designation during his or her junior year. The student will enroll in either PHYS 4375 or 4390 during the program, and a senior thesis is to be written and presented to the faculty.

Simultaneous Degree Programs. It is also possible to earn simultaneously a B.S. degree in physics from Dedman College and a degree in engineering from the School of Engineering. The undergraduate adviser of the Department of Physics should be consulted for detailed information on the simultaneous degree programs.

Students with a strong high school preparation in physics may take a departmental placement examination to acquire credit for either PHYS 1303 or 1304; the placement exam must be taken during the student's first semester at SMU.
