Introductory Courses for the Major
Students who major in physics usually start by taking an introductory physics course: PHYS 131 and PHYS 151 in the fall, or PHYS 143 or 144 in winter, or PHYS 142 in spring, and two or three terms of calculus. PHYS 131 deals with Newtonian mechanics, and PHYS 151 concentrates on special relativity and particles. PHYS 144 looks at physics on an astronomical scale, and is suitable for students with a strong background in calculus and/or AP physics. PHYS 142 and 143 are the ten-week courses that we recommend for students who have no previous experience with high school physics, and who are just starting their math sequence. PHYS 142 in the spring course includes an extra day with a problem-solving component.
Every spring term, both prospective and declared majors are encouraged to take PHYS 123 (What Physicists Do). This one-credit course brings to campus alums and others who are making active use of their background in physics or astronomy. Each visitor gives a talk on his or her work and students have ample opportunity for more personal interaction, over snacks after the talk.
Most prospective majors take an introductory course their first year at Carleton and PHYS 228 and PHYS 231 as sophomores. If they do declare a physics major, it will be while continuing in PHYS 235 in spring term. Some students enter the major having delayed an intro course until as late as winter term sophomore year. It is still easily possible to complete the major after a late start, though most students in this situation will not be able to take some of the upper-level elective courses.
