# Department of Physics

Department website: http://physics.ncsu.edu/

Physics is the fundamental science of observation, measurement and description of the natural world. Physicists seek to establish a mathematical description of all physical phenomena, ranging from the interactions of quarks in nuclei to the collisions of galaxies in the universe. Together with scientists in engineering and other physical, biological, and mathematical sciences, physicists collaborate to develop new materials and new insights in all areas of modern science and technology.

## Curricula

The Physics undergraduate curricula provide a strong background in the fundamentals, and offer course options for deeper studies in areas of interest. Undergraduates have the opportunity to work in research laboratories with faculty in: astrophysics, atomic physics, biological physics, physics education, nuclear and particle physics, near-field optics, and materials physics, solid-state and condensed-matter physics. Undergraduates are frequently co-authors on scientific papers. Physics majors are part of a close-knit community- a small highly motivated group of people who have wide-ranging interests and a passion for solving problems.

Specific curriculum requirements are available online.

## Bachelor of Science in Physics

This degree equips students with a broad technical background, providing a solid basis for graduate study in physics or related sciences, enrollment in professional schools such as law or medicine, and employment in government or industrial laboratories.

## Bachelor of Arts in Physics

This degree offers a flexible course of study for students who may not plan to become professional physicists but who desire an interdisciplinary program with a strong emphasis on physics. The proper choice of electives will help to prepare the graduate for professional careers in education, law, business, journalism, or graduate school in an allied science. It is especially suitable as part of a double major or as preparation for high-school teaching.

## Honors Programs

The Department of Physics Honors Program offers students the opportunity to develop their academic potential by increased involvement and participation in physics study and research. To graduate with physics honors, students must complete the equivalent of three (3) hours of PY 499 Independent Research in Physics with a written scientific report based on their results. Students must also complete an additional nine (9) hours of 500-level physics courses. One 400 level physics course (excluding PY 407) taken with the honors contract may be substituted for a 500 level course.
