## Minors Offered

**Physics**

*Matter, energy, space and time* obey a few general but precise laws, which are fundamental to the structure and behavior we see in our universe. The evolving understanding of this over the centuries has changed our minds, our lives, and our world profoundly.

The Physics Department helps students understand and explore these natural relationships, their meaning, interconnectedness, and their use. The study of physics includes mastering very broad fundamentals which apply to everything from atoms to galaxies, as well as specific studies in topical specializations such as computational and astrophysics. Students are also encouraged to participate in undergraduate research projects both here at Pacific and at other institutions during the summer break.

## Degrees in Physics

The degree programs in Physics prepare students to think deeply through questions, to find and connect abstract relationships to new situations, and to be academically confident and broadly knowledgeable scientists and teachers. Bachelor of Science degrees are offered in Physics and Engineering. A Bachelor of Arts degree is also offered in Physics, which is combined with the credential program for secondary school teaching. The department also offers a Physics Minor, intended for students majoring in other disciplines, who have a strong interest in Physics and the underlying principles of science.

## Facilities

The Physics Department occupies Olson Hall. Labs are equipped with modern facilities for advanced experiments in quantum optics and condensed matter physics, astrophysics, particle physics, ultra-high vacuum and thin film fabrication, and a 2.3 meter radio telescope for student use. The department has three computer-equipped labs for introductory physics, musical acoustics, and astronomy courses, a scientific computing lab, a machine shop and an electronics shop. Additionally there is ample space for student research projects. Olson Hall features room 120 with 90 seats and state-of-the-art computer displays for large lectures, as well as a number of smaller classrooms.

## Recommended High School Preparation

Physics majors should be prepared to take calculus in their first semester at Pacific, and it is highly recommended that they take high school physics and chemistry. Some experience with computer programming in a language such as C++ or Python is also useful.

## Bachelor of Arts - Physics

The Bachelor of Arts degree program requires fewer advanced courses in Physics and Mathematics than are required for the three Bachelor of Science programs. Students complete six courses in Physics and four in Mathematics, which allows time for a student to develop greater breadth in other areas as is appropriate for a high school physical science teaching credential. Thus, this degree is at present limited to students in the secondary school teaching track. (Students interested in teaching credential programs with a physics or physical sciences emphasis can obtain the Teaching Credential Major sheet from the Office of Admissions.)

## Bachelor of Science - Physics

The Bachelor of Science in Physics degree program is the standard preparation for professional careers in physics and related physical sciences. Graduates may enter industrial and government positions directly at the BS level or may proceed to graduate study in preparation for higher level research positions.

In addition to the *Standard Track* for the Bachelor of Science in Physics described above, students may choose a focused concentration for their studies, and follow one of the three concentrations below. These concentrations engage the student further in areas where our department has particular expertise and resources.

### Computational Physics Concentration

This concentration enhances the student’s understanding and experience in using computers to solve physics problems and build simulations of complex phenomena, that use the department’s high performance computing resources. Students in this concentration are required to take PHYS 127 and one other applied Math or Physics course, and their Senior Thesis (PHYS 199) is a computationally intensive project.

### Astrophysics Concentration

Through coursework and projects that uses the department’s astronomical telescopes (optical and radio) and other equipment, students in the Astrophysics Concentration enhance their understanding of the Universe beyond the Earth. Students in this concentration are required to take PHYS 041 and PHYS 141, and their Senior Thesis (PHYS 199) involves either an experimental or theoretical astrophysics project.

### Mathematical Physics Concentration

This concentration is for students who are mathematically gifted or might be considering a dual major in Math. Students in the Mathematical Physics Concentration are exposed to more advanced techniques and aspects of theoretical physics. The requirements of this concentration are PHYS 137 and another upper division MATH elective, and the Senior Thesis (PHYS 199) involves a theoretical investigation.

## Bachelor of Science – Engineering Physics

The Bachelor of Science in Engineering Physics is offered in cooperation with the School of Engineering. The proportions of courses taken in these two areas are roughly equal.

Today’s engineer must be able to understand and apply new and changing technologies which arise from advances in fundamental science. Pacific engineering physics graduates have a firm understanding of the fundamental physics upon which modern technologies are based. He or she is able to use advanced mathematical methods and problem solving techniques to relate new ideas and scientific developments to practical problems in engineering. By acquiring skills applicable for lifelong learning, the Pacific engineering physics graduate is well prepared for a competitive career.

Students who pursue a Bachelor of Science in Engineering Physics degree are subject to all of the requirements of an engineering degree student. Among these requirements is a work experience component called the Cooperative Education Program. Students must complete 32 units of full-time work experience in order to graduate. See the Engineering and Computer Science, Cooperative Education for Engineering Programs section of this catalog for more details.

## The Physics Minor

A minor in Physics provides the student of any discipline with a very strong understanding of the foundations of science and the workings of the physical world. The study of physics teaches abstract problem solving skills which are both of great benefit to the student, and impressive to prospective employers.
