Purpose Statement

Physics seeks to explain everything from the structure, evolution, and formation of the universe to the nature of matter and energy. Astrophysics is the application of physics to celestial bodies and seeks to understand the formation, structure, and evolution of stars, planets, galaxies, and the universe. At its heart, physics aims to provide fundamental and predictive explanations to observed phenomena, establishing relationships between measurable quantities, and developing mathematical models to interpret, leverage and understand these phenomena. The physics and astrophysics major emphasizes foundational skills for understanding key physical phenomena in astrophysics, including matter, motion, energy, electricity and magnetism, quantum theory, and gravity, including Einstein´s theory of general relativity. Students will acquire the skills to understand the observed abundance of the elements, the age of the universe, the nature of gravitational waves, and the cosmic microwave background. Through a mastery of physics and astrophysics, students will develop advanced mathematical, computational, and experimental skills. Major work is completed through classroom and laboratory exercises. The critical thinking, scientific analysis, and communications skills obtained through the completion of a physics and astrophysics degree will prepare graduates for entry to graduate and professional schools, industry careers, and research laboratory work.

Major Requirements
  • This major requires 72 - 74 units.

    Take the following 72 - 74 units:

    • *PHY 171 and PHY 172 are recommended in consultation with your advisor.

  • Students enrolled in this plan may not enroll in or pursue the following due to the number of overlapping units:

General Electives
  • Additional coursework is required if, after you have met the previously described requirements, you have not yet completed a total of 120 units of credit.

    You may take these remaining courses from any of the academic areas, using these courses to pursue your specific interests and goals. You may also use prerequisites or transfer credits as electives if they weren't used to meet major, minor, or liberal studies requirements.

    We encourage you to consult with your advisor to select the courses that will be most advantageous to you.

Additional Information
  • Please note that you may not count more than one grade of "D" in a physics or astronomy course toward the major requirements for this degree.

  • Be aware that some courses may have prerequisites that you must also successfully complete. For prerequisite information, click on the course or see your advisor.
