Typical Programs of Study
In the programs suggested below, the courses in parentheses are optional; the others are required for the major. Keep in mind that these programs are flexible and are intended only as guidelines for planning a sequence of courses for the physics major.
PROGRAM A: The most common sequence.
Fall Term  Winter Term  Spring Term

Junior  PHYS/ASTR Elective 
PHYS 335:Quantum Mechanics  PHYS 342: Contemporary Experimental Physics PHYS/ASTR Elective 
The senior year is open except for comps, which normally demand work equivalent to a sixcredit course. For students planning on graduate work in physics, a typical senior year is as follows:
Fall Term  Winter Term  Spring Term  
Senior  [PHYS 355: Advanced Mechanics] 
PHYS 400: Comps  PHYS/ASTR Elective 
* Note that 131 may be skipped upon successfully passing the departmental placement exam, with 141 strongly suggested as a replacement for 131.

Integrative Exercise (Comps)
Passing an integrative exercise, or "comps," is part of the requirement for completion of the baccalaureate degree at Carleton. Comps is usually taken during the senior year, although in some cases (double majors, 32 program) comps may be taken during the junior year.
We conceive of comps as a learning and sharing experience for both students and faculty. The integrative exercise in physics consists of an extensive study by each student in some field and/or topic in physics, culminating in a 70minute presentation during the winter or spring term. In addition two papers are required: a short introduction before the presentation and a longer summary after it. Each year the final papers will be bound and made available to the public in the library and at the departmental office; students also have the option of storing their comps electronically in the library. The topic chosen may involve a currently active field of research, a significant development in the history of physics, or an integrative theme from the physics curriculum. It must be sufficiently broad to allow the student to synthesize material from the various courses required for the major. Past topics have included solar satellite power systems, the aurora borealis, gravitational waves, optical fibers, universality in chaos, controlled nuclear fusion, atmospheric tides, scanning tunneling electron microscopy, residential application of solar power, and superfluid helium and its vortices. Comps represents a stringent test of a student's integration of knowledge, research and independent study skills, and writing and speaking ability. It also involves group interaction, with students listening to, questioning, and offering written criticism of each other's presentations. Seniors are required to attend ten comps talks in the department and write reflection papers on two of the comps talks.
