Physics, B.S.

The physics major at Saint Louis University provides a foundation for all the natural sciences and engineering disciplines. Physics has brought many revolutionary ideas such as relativity, quantum mechanics, and the Big Bang Theory, profoundly altering how humankind views the universe.

Physicists have made many breakthrough discoveries. The invention of the transistor by physicists has made the modern computer possible, while the development of lasers has led to diverse applications ranging from supermarket scanners to laser surgery. Physicists are versatile problem solvers and excel in many technical fields.

Training in physics leads to a broad-based understanding of natural phenomena, analytical and computer skills, experience with electronics and the operation of sophisticated equipment, an understanding of measurements and their limitations, and the ability to formulate and solve complex technical problems. Physics majors desire to understand the physical universe around them. They are interested in questions such as “Why do elementary particles behave the way they do?” “What is the nature of light?” or “How did the universe begin, and what will eventually happen to it?” Some physics students pursue double majors in mathematics, computer science or an engineering field.

Physics students who also like to explore other languages and cultures can study at SLU’s campus in Madrid, Spain. International study within the physics discipline opens your horizons and prepares you for success in an increasingly global job market. SLU-Madrid offers the required coursework for the first three semesters of the physics major, making studying abroad an exciting option for pursuing a physics degree at SLU.

Curriculum Overview

SLU's B.S. in physics focuses on both fundamentals and applications of physics. It includes many opportunities to participate in cutting-edge research.

Physics majors gain a solid foundation in analytical, computational and laboratory skills through physics coursework. The physics curriculum includes courses in classical mechanics, quantum mechanics, electricity and magnetism, thermodynamics and statistical mechanics, optics, electronics, modern and solid-state physics, as well as nanoscience and nanotechnology.

Non-Course Requirements

  • All physics majors must complete an exit interview with the department chair during their final semester. 
  • All B.S. students are required to submit an undergraduate thesis prior to graduation. 

Fieldwork and Research Opportunities

The benefits of SLU's physics program also include several internship and career opportunities. The physics department employs some of its students as teaching and research assistants during the summer. Students have held summer internships at NASA-Langley, the Argonne National Laboratory and other laboratories. Students have worked during the summer and during the year at local industries such as Boeing and Anheuser-Busch. Numerous opportunities exist for summer research in basic and applied physics in the School of Science and Engineering, national laboratories and National Science Foundation-sponsored programs at universities throughout the United States.

SLU's physics program engages students in exciting research opportunities in experimental, computational or theoretical physics. New state-of-the-art research laboratories allow students to work directly alongside faculty members on research projects.


Graduates with a bachelor’s degree in physics enter various careers that depend on the technical skills gained in college. Alumni are employed in product development and quality control in large industries such as RCA, Boeing and Lockheed-Martin. Alumni are computer specialists at Anheuser-Busch and other companies. Some are now involved in the marketing of technical products, while others are in management positions. A few graduates have entered military careers. Students frequently earn double majors, combining physics with mathematics, computer science or chemistry.

Admission Requirements

Begin Your Application

Saint Louis University also accepts the Common Application.


All applications are thoroughly reviewed with the highest degree of individual care and consideration to all credentials that are submitted. Solid academic performance in college preparatory coursework is a primary concern in reviewing a freshman applicant’s file.

To be considered for admission to any Saint Louis University undergraduate program, applicants must be graduating from an accredited high school, have an acceptable HiSET exam score or take the General Education Development (GED) test. 


Applicants must be a graduate of an accredited high school or have an acceptable score on the GED.

Students who have attempted fewer than 24 semester credits (or 30 quarter credits) of college credit must follow the above freshmen admission requirements. Students who have completed 24 or more semester credits (or 30 quarter credits) of college credit must submit transcripts from all previously attended college(s).

In reviewing a transfer applicant’s file, the Office of Admission holistically examines the student’s academic performance in college-level coursework as an indicator of the student’s ability to meet the academic rigors of Saint Louis University. Where applicable, transfer students will be evaluated on any courses outlined in the continuation standards of their preferred major.

International Applicants

All admission policies and requirements for domestic students apply to international students along with the following:

  • Demonstrate English Language Proficiency
  • Proof of financial support must include:
    • A letter of financial support from the person(s) or sponsoring agency funding the time at Saint Louis University
    • A letter from the sponsor's bank verifying that the funds are available and will be so for the duration of study at the University
  • Academic records, in English translation, of students who have undertaken postsecondary studies outside the United States must include the courses taken and/or lectures attended, practical laboratory work, the maximum and minimum grades attainable, the grades earned or the results of all end-of-term examinations, and any honors or degrees received. WES and ECE transcripts are accepted.

Additional Admission Requirements

In addition to the general admission and matriculation requirements of the University, the B.S. in physics program has the following additional requirements:

  • GPA: Minimum cumulative 3.00 high school GPA for freshmen applicants and 2.70 college GPA for transfer applicants.
  • Coursework: Fifteen total units of high school work are required: three or four units of English; four or more units of mathematics, including algebra I and II, geometry and precalculus (Algebra II with Trigonometry is not sufficient). Students should be prepared to start the first semester of freshmen year in Calculus I or higher; three or four units of science, including general science, introduction to physical science, earth science, biology, physics or chemistry; two or three units of social sciences including history, psychology or sociology; and three units of electives.

Admission requirements are based on a combination of secondary school grades, college admission test scores, co-curricular activities and attempted college coursework, as well as other indicators of the applicant’s ability, career focus and character. This process respects SLU's non-discrimination policy and is designed to select a qualified, competent and diverse student body with high standards of scholarship and character, consistent with the University's mission.
