The goal of physics and astronomy is a unified description of the properties of matter and energy. The study of matter and energy encompasses a range of phenomena, from the subnuclear to the cosmological. Physics seeks to understand the way the universe “works,” from the very small scale (quarks and neutrinos) to the human scale (materials encountered in daily life) to the very large (the structure of the cosmos). Different approaches and technologies are used in these different regimes.

## Sample Plan of Study

Sample plans can be used as a guide to identify the courses required to complete the major and other requirements needed for degree completion within the expected eight semesters. The actual degree plan may differ depending on the course of study selected (second major, minor, etc.). Students should meet with their academic advisor to create a degree plan that is specific and unique to their interests. The sample plans represented in this catalog are intended for first-year students entering UNC–Chapel Hill in the fall term. Some courses may not be offered every term.

## Special Opportunities in Physics and Astronomy

### Honors in Physics and Astronomy

The honors program offers exceptionally well-qualified students an opportunity to perform original research with a faculty member and graduate with honors or highest honors. It requires an overall grade point average of at least 3.3 and a grade point average of at least 3.4 for physics courses at the end of the junior year.

Students who wish to enter the honors program should consult with the departmental coordinator for the program no later than the preregistration period in the spring semester of their junior year.

### Departmental Involvement

The Society of Physics Students, open to anyone interested in physics, builds connections between undergraduates, graduate students, faculty, and alumni. The society invites visitors to give talks and sponsors a number of events for students each year. Women in Physics at UNC–Chapel Hill, an organization that aims to provide resources, advice, and an encouraging social atmosphere for women in the field of physics, welcomes physics majors and all women interested in physics.

### UNC–BEST

The UNC Baccalaureate Education in Science and Teaching (UNC–BEST) Program is a collaboration between the School of Education and the College of Arts and Sciences and is designed to allow undergraduate science majors interested in teaching high school science the opportunity to earn their science degree and obtain licensure as a North Carolina high school science teacher in four years. UNC–BEST students meet all the degree requirements for their degree using PHYS 410 as one of their upper-level physics courses.

Code | Title | Hours |

PHYS 410 | Teaching and Learning Physics | 4 |

EDUC 689 | Foundations of Special Education (may substitute EDUC 516) | 3 |

EDUC 532 | Introduction to Development and Learning (may substitute EDUC 403) | 3 |

EDUC 593 | Internship/Student Teaching | 12 |

EDUC 601 | Education Workshops | 1 |

For more details on admission requirements, application deadlines, and submitting an online application, visit the School of Education Web site.

### Undergraduate Awards

The department gives awards each year to the senior (Shearin Award) and junior (Johnson Award) who demonstrate the greatest achievement. In addition, the department awards the major with the most research achievement the Robert Sheldon Award for Undergraduate Research.

### Undergraduate Research

All majors conduct at least one semester of research under the supervision of a faculty member. Many enjoy the experience so much that they continue for several semesters. An approved learning contract is required prior to registering for PHYS 295 and PHYS 395, and students must be registered within the first week of classes.
