The department seeks to train students to think analytically in terms of the fundamental principles of physics. We provide meaningful and welcoming courses to a diverse group of students who are majors in physics and astronomy, majors in other sciences, and majors in departments outside the sciences. Subject matter in introductory courses is selected to illustrate basic phenomena of nature, their regularity, and their technological applications. The Physics 141, 145 (previously 142) course sequence provides a solid basis for further work in physics as well as preparation for medical school and advanced study in other sciences. These courses also provide excellent preparation for students who plan to enter professions such as law, teaching, and business. Advanced course offerings in the department provide a strong background for graduate study in physics, astronomy, engineering, and interdisciplinary fields such as biophysics, environmental science, medical physics, and bioengineering.

Emphasis is placed upon independent work and cooperative research with the faculty in atomic, molecular, and optical physics, condensed-matter physics, theoretical physics, and infrared astronomy. All faculty members have active research programs that thrive on undergraduate contributions. Research projects make use of the department's well-equipped laboratories, computer workstations, and supporting machine, electronic, and technical shops.

Students seeking a career in engineering may consider applying to an exchange program in which both a bachelor of arts and a bachelor of engineering can be earned upon successful completion of three years at Colby and two years at Dartmouth College. This program is coordinated by the Physics Department but does not require that the participating student be a physics major at Colby. Students should consult with the engineering advisor before selecting their first-semester courses.

Physics 141, 145 (or 142), 241, and 242 form a full introduction to classical and 20th-century physics. For students with a previous background in physics and calculus from high school, Physics 143 may be taken instead of Physics 141.

 
Requirements for the Physics Major
Physics majors have a lot of flexibility in choosing the courses that are most appropriate for them. Students should work closely with their advisors in selecting courses to fulfill the requirements for the major. Not all upper-level elective courses are offered every year.  Physics 415, taken in the fall of the senior year, involves completing an independent project, internship, or research in physics or a related field. All students are invited to attend the colloquia presented by faculty, senior students, and visiting scientists; senior physics majors are required to participate by enrolling in Physics 401, 402. The point scale for retention of the major applies to all courses taken that can satisfy the requirements listed below. No requirements for the major may be taken satisfactory/unsatisfactory.

Honors Program in Physics
In the junior year, physics majors may apply for admission to the honors program. A 3.25 grade point average in physics and mathematics courses is normally required. Successful completion of the honors program will result in the degree being awarded “With Honors in Physics.” A thesis completed as part of the Senior Scholars Program may be substituted for the honors thesis.
 
Requirements for the Honors Major
In addition to fulfilling the requirements for the basic physics major, students must take three additional 300-level or higher physics courses and one additional 200-level or higher mathematics course. In fulfilling these requirements, students must take at least one upper-level experimental course (Astronomy 231, Physics 254, 333, or 334). In their senior year, they must also take Physics 483-484 Independent Honors Project in the place of Physics 415. A written honors thesis is required.

Students considering graduate school in physics or astronomy are strongly encouraged to take all of the following courses: Mathematics 253, 302, 311, 352, Physics 254, 311, 321, 332, and 431.
 
Requirements for the Minor in Physics
Physics 141 (or 143), 145 (or 142), 241, 242 (or a physics course numbered 300 or above), Mathematics 121 (or 161), 122 (or 162). 

Effective for the graduating class of 2012, no requirements for the physics minor may be taken satisfactory/unsatisfactory.
