Physics Major | LSU


You are interested in learning about the universe around us, as well as within us.

About Our Physics Major

Whether it’s discovering a new particle or blasting a rocket into space, physics is at the root of everything. While pursuing a physics major at LSU, you will learn about energy and matter, electromagnetism, quantum mechanics, the birth of the universe, and Einstein’s special theory of relativity. Our program will prepare you for graduate school in physics, leading to careers as a college professor, as a scientist at a government agency (like NASA), or in high-tech industry. 

Concentrations Available:

  • Astronomy: Astronomers challenge the way we look at the universe and our role in it. While the casual observer may think it’s all about stargazing, astronomy is heavily rooted in physics and math. As a physics-major student, you will take elective courses in stellar and galactic astrophysics and modern optics, and carry out an observational astronomy project at the Highland Road Park Observatory.
  • Medical Physics: This is for students interested in careers in medical physics and health physics or those intending to pursue a physics degree as a pre-med student. In this concentration you will take courses in chemistry, biology, and kinesiology, as well as core physics and specialized medical physics courses.
  • Physics and a Second Discipline: This area of focus is for students who wish to combine the study of physics with another subject, either a minor or a double-major, in order to tailor their degree to their interests and career goals.
  • Secondary Education: This concentration allows you to pursue an undergraduate degree in physics and earn a secondary teaching certificate at the same time though the LSU GeauxTeach Math & Science program.
