Why study physics at Gettysburg College?

Society needs individuals who are willing to solve complex problems through logical reasoning. The Gettysburg College physics major prepares students to face various challenges, from analyzing large swaths of data for a government agency to creating processes to streamline production or educating others on how to solve difficult problems.

The Physics Department at Gettysburg College offers majors in physics toward the B.A. and B.S. degrees, as well as a minor and a dual degree in engineering. Each component of the bachelor’s in physics degree program prepares you to branch out into the diverse sectors of business, education, engineering, government, research, or technology.

Through the Gettysburg Approach, physics majors receive A Consequential Education that imparts a breadth and depth of knowledge through a rigorous liberal arts and sciences curriculum. Meaningful experiences in coursework and co-curricular activities obtained through the Guided Pathways enable students to build enduring skills such as critical thinking and problem solving to serve them in all their endeavors beyond Gettysburg.

Major in physics

The physics program is highly flexible, allowing you to curate your upper-level courses around your scientific interests. Both the B.A. and B.S. in physics require you to enroll in labs, foundational physics courses, upper-level physics courses, and participate in a research experience either during a summer experience or in a senior capstone course. Students in the Bachelor of Science in physics degree program take additional physics and math courses and are well prepared for industry or graduate school in physics, astronomy, or engineering. Due to the close overlap between physics and engineering, the physics major provides an excellent preparation for dual-degree engineering programs as well as engineering graduate programs.

The integration of a liberal arts and sciences curriculum encourages physics majors to actively engage with their peers and the world around them to solve problems.

Dual degree in engineering

Physics majors seeking two bachelor’s degrees have the unique opportunity to enroll in the dual-degree engineering program. This program combines the communication skills and creativity of a liberal arts education of the B.A. in physics degree program with the rigor of a highly regarded engineering program through one of four affiliated universities:

  • Columbia University
  • Rensselaer Polytechnic Institute
  • Washington University
  • University of Pittsburgh

Successful completion of the dual degree in engineering degree program awards students with a Bachelor of Arts in physics and a Bachelor of Science in an engineering discipline from one of the four affiliated universities listed above. Below are several of the engineering degrees offered:

  • Biomedical engineering
  • Chemical engineering
  • Civil engineering
  • Computer engineering
  • Electrical engineering
  • Environmental engineering
  • Materials engineering
  • Mechanical engineering
  • Systems engineering

What makes Gettysburg’s Physics Department different?

The Gettysburg College Physics Department emphasizes experiential learning in our classrooms, in our laboratories, and during research experiences. We emphasize theoretical and experimental experiences through several upper-level theoretical and experimental courses. Through the Physics Department, physics majors and physics minors have opportunities to participate in Gettysburg College’s premier research program, the Cross-Disciplinary Science Institute (X-SIG), which aims to make students Research Ready, Research Active, and Research Connected.

Students have access to unique facilities, such as the newly renovated Hatter Planetarium, CPU and GPU clusters, a plasma lab, a biophysics lab, a quantum-optics lab, a nuclear lab, a plasma lab, an observatory, and an in-house proton accelerator.

Through our course design and strong community, the Physics Department welcomes all interested students and is dedicated to ensuring their success.

Undergraduate research

The physics major at Gettysburg places a significant focus on research. You can participate in independent research, off-campus research, and student-faculty research. If you do not participate in a mentored research experience during the summer, you will have the opportunity to do hands-on research in your senior capstone course.

Physics majors may also gain valuable, real-world experience as a student assistant within the Physics Department through the following roles:

  • Laboratory assistants
  • Laboratory equipment setup
  • Research assistants
  • Special services
  • Student checkers

Students interested in becoming a student assistant are encouraged to speak with a physics faculty member at the start of each academic semester.
