Overview

    The physics curriculum is designed to provide a broad foundation in the physical sciences, as well as specialized training in classical and modern physics, and it may lead to either a B.S. or a B.A. An honors student may also qualify for a five-year program leading to both the B.S. and M.S. Experimental opportunities are available in such fields as fundamental particle physics, nuclear physics, condensed matter physics, laser optics, radio astronomy, and multimedia teaching demonstrations. Superior students are encouraged to participate with faculty members in undergraduate research projects. Computers are available for use by all physics majors.

    Liberal emphases in the physics curriculum permit students to give special attention to those aspects of the discipline they prefer and enable them either to pursue a traditional course of study as preparation for joining the technical staffs of industries or government laboratories, or for graduate studies in physics (B.S.); or to pursue an interdisciplinary course of study with a strong background in physics (B.A.).

    A handbook that includes sample curricula for emphases in astrophysics, chemistry, computer science, education, electrical engineering, finance; geophysics, materials science, and mathematics is available from the department on request.

    The requirements for the B.S. are, in addition to the college curriculum and the Curriculum for Liberal Education: Phys 2305, 2306, 3304 (or 3455 and 3504), 3314, 3355, 3356, 3405, 3406, 3704, (or 4504 or 4554), 4315, 4316, 4455, 4456; Math 1114, 1205, 1206, 1224, 2214, 2224, 2984 (Linear Algebra-2 cr.), 4564 (or 4425), and Chem 1035, 1036, 1045, 1046. Outstanding students may also elect to complete the requirements for a B.S. "in honors." A description of this honors program in physics is included in the handbook indicated above. The requirements for the B.A. are, in addition to the college curriculum and the Curriculum for Liberal Education: Phys 2305, 2306, 3304, 3314, 3355, 3356 (or 3405), 3655 (or 3656), 3704, 4315; Math 1114, 1205, 1206, 1224, 2214, 2224; 14 specific credits of Biology or Chemistry or Geology; and Hist 3705, 3706. The department also offers the M.S. and Ph.D. in physics (see the Graduate Catalog).

    Transfer students should contact the department early, preferably one full semester prior to entrance. This procedure will allow a thorough evaluation of transfer credits and correct placement.

    A student may obtain a minor in physics by registering with the department and successfully completing 2305, 2306, (or 2175, 2176, and two physics laboratory credits), 3304, 3355 (or 3405), 3704, plus three more physics credits at or above the 3000 level.

    A minor in astronomy is also available and may be obtained by registering with the department and successfully completing 1055, 1056, 1155, 1156, 3154, 3655, 3656, and one more course from an approved list (see J. H. Simonetti).

    The department participates in the Cooperative Education Program in which a student may alternate through two successive years a semester of study with a semester of professional employment in his/her discipline; these two years normally replace the student's sophomore year. Additional information on the program is included in the "Academics" chapter in this catalog and in the handbook indicated above.

    Any student who completes for credit Physics 2004 or 2014 while having already passed (with a grade of D or better in the A-F option or P in the P/F option) Physics 2175, 2205, or 2305, will have such credit in 2004 or 2014 converted to "audit" before his/her graduation.

    University policy requires that students who are making satisfactory progress toward a degree meet minimum criteria toward the Curriculum for Liberal Education (see Academics chapter in this catalog), toward the College of Science Core (see first part of this chapter), and toward the degree in physics.
