Majors & Minors

Physics Major | Physics Minor

General Distribution Requirement

All courses in the physics and astronomy department except some topics courses and those numbered PHYS 614, PHYS 624, PHYS 634 and PHYS 644 count toward the general distribution requirement in mathematics and natural science.

General Education Requirements

Courses that meet the general education requirements in writing, quantitative thinking, internationalism and U.S. identities and differences will be posted on the Registrar's web page in advance of registration for each semester.

Additional information regarding the general distribution requirement and the general education requirements can be found in the graduation requirements section of this catalog.

Honors Program

The physics and astronomy department participates in the honors program. Eligibility requirements, application procedures and specific project expectations for the department are available from either the department office or the Academic Programs and Advising Office.

Topics Courses

PHYS 194, PHYS 294, PHYS 394, PHYS 494 

These temporary courses are offered by instructors at their own initiative or in response to student requests. The following are examples of recent offerings: Computational Physics, and Research in Astrophysics. To be announced at registration. (2-4 credits)

Independent Study

The department offers independent study options in the form of independent projects, internships, preceptorships and Honors independent projects. For more information contact the department and review the Curriculum section of the catalog.

Physics Major

Major Requirements

The Physics department offers two majors: Physics and Physics with Astronomy Emphasis. All majors will take a common core of physics courses and additional supporting math courses. Under supervision of one or more physics faculty, majors are also required to complete a capstone (or honors) project during their senior year A major in physics provides a rigorous study of many topics in the field that are fundamental for every scientific and technological discipline. The physics major is particularly appropriate for students wishing to pursue graduate study in physics, astronomy, engineering, medicine and related areas, as well as for those seeking positions in technology-oriented business and industry. For example, a double major in physics and computer science would be excellent preparation for graduate study in computer engineering.

Majors must take a minimum of 39 credits in physics (9 core physics/astronomy courses, plus 3 terms of Physics Seminar), as well as 4 supporting math courses.

Supporting Math Courses

MATH 135 - Applied Multivariable Calculus I

MATH 137 - Applied Multivariable Calculus II

MATH 236 - Linear Algebra

MATH 237 - Applied Multivariable Calculus III

Capstone

Physics majors are also required to engage in an original research project which will meet Macalester's Capstone requirement. This consists of a written paper and talk presented during physics seminar during senior year.

Sequence of Courses

Many physics courses require prerequisites or co-requisites, and some classes are only taught once per year. The Course Dependency Charts and Sample Schedules pages are helpful resources for planning.
Department faculty can also provide guidance.

Additional Course Recommendations

Information and guidance around course selection for sub-disciplines (astronomy, astrophysics, engineering, etc.), choosing electives, and planning for graduate work or employment in the field is
available from the faculty in the physics and astronomy department.

For Physics with Astronomy Emphasis majors with little or no astronomy background we strongly recommend starting with PHYS 113 - Modern Astronomy I.

Students intending to pursue graduate study in physics, astronomy, engineering or other closely related disciplines should consult with a department faculty advisor to consider which advanced elective
courses would be most appropriate for their career goals. For example, preparation for graduate study in physics should include MATH 312 - Differential Equations, PHYS 444 - Electromagnetic Theory II, and PHYS 482 - Advanced Quantum Mechanics. Students considering graduate work in astronomy or astrophysics should strongly consider taking PHYS 481 - Quantum Mechanics.

Pre-Engineering

While Macalester does not offer engineering courses, students considering graduate work in engineering should consult the pre-engineering webpage.

Physics Plus Program

The Physics Plus program was created based on feedback from alumni enrolled in premier graduate physics programs. Its purpose is to provide further preparation to those majors who intend to enroll in graduate school after graduation. The program requires majors to complete at least two out of three second semester courses in Quantum Mechanics (PHYS 482), Electrodynamics (PHYS 444), and Astrophysics (PHYS 460), and at least one additional special topics course or elective, numbered above 331, beyond the core physics curriculum. The department provides majors who complete the Physics Plus program with an official letter, explaining the program and confirming that the student has met its requirements.

Sequence of Courses

Engineering

Macalester does not offer engineering courses. However, students who desire to pursue engineering as a career may earn a graduate degree in an engineering field after graduation from Macalester.

Physics Major with Astronomy Emphasis

This option is designed for students with a strong interest in astronomy and astrophysics who may be contemplating post-graduate work in these areas. The physics major with astronomy emphasis includes the following courses required for the physics major:

PHYS 226 - Principles of Physics I
PHYS 227 - Principles of Physics II
PHYS 331 - Modern Physics
PHYS 370 - Computational Physics
PHYS 443 - Electromagnetic Theory I
PHYS 461 - Mechanics
PHYS 468 - Statistical Mechanics
PHYS 489 - Physics Seminar (1 credit)

In addition, students must take

PHYS 460 - Astrophysics
PHYS 440 - Observational Astronomy

The capstone requirements for a physics major with astronomy emphasis are identical to those for a physics major. The department allows AP or transfer credits for PHYS226 and/or PHYS227 to apply to the major and to the minor. Credits awarded for these classes satisfy the major/minor requirements and also count toward the total number of credits required to satisfy the major/minor.

For students with little or no astronomy background we strongly recommend starting with PHYS 113 - Modern Astronomy I and PHYS 120 - Astronomical Techniques. Students considering graduate work in astronomy or astrophysics should also consider taking PHYS 481 - Quantum Mechanics.

Those students choosing a major with an astronomy emphasis will have this noted on their transcripts (e.g. Physics Major with Astronomy Emphasis).

Physics Minor

Minor Requirements

The department also offers a minor consisting of 5 courses:

• PHYS 226 - Principles of Physics I*
• PHYS 227 - Principles of Physics II*
• PHYS 331 - Modern Physics
• Any two physics and astronomy courses numbered above 331.

*Note that MATH 135 - Applied Multivariable Calculus I, and MATH 137 - Applied Multivariable Calculus II are pre/co-requisites for PHYS 226/227.
