Completion of a minimum of 20 units in physics courses, including not more than one first course or more than one second course, constitutes a minor in physics. (First courses are PHYS 100, PHYS 210A, and PHYS 114, and their equivalents taught elsewhere. Second courses are PHYS 210B, PHYS 214, and their equivalents.) Interested students should consult with the academic advisor in the Department of Physics and Astronomy.
