# Introductory Courses

Introductory physics courses for premedical, predental, and other preprofessional students may be chosen from CAS PY 105, 106, or 211, 212, or 241, 242. CAS PY 105, 106 and 241, 242 cover all of classical and modern physics in two semesters. CAS PY 211, 212 cover classical physics only. CAS PY 212 may be followed by CAS PY 313, which includes modern physics. Physics and other science concentrators or engineers with an interest in physics may elect the more intensive CAS PY 251, 252, which is usually followed by CAS PY 351. The four introductory sequences differ primarily in the level of mathematics employed. CAS PY 105, 106 assume a knowledge of algebra and trigonometry only. The other sequences require knowledge of calculus, which is used most extensively in CAS PY 251, 252. Many of these courses include demonstrations supplied by the Physics Department Lecture Demonstration Facility.
