Physics is the most fundamental of sciences. Taking as its domain all forms of matter and energy, it seeks to discover the laws that govern the behavior of material objects and waves, and the interactions between particles. Application of these universal laws to systems ranging from atoms and molecules to clusters of galaxies gives rise to challenging problems whose solution requires creative insight alongside logical rigor and mathematical reasoning.

 

Study of physics helps the student understand the scientific method and its implications—how to make rational inferences from data and how to test hypotheses critically. It also leads to an appreciation of the aesthetic dimensions of a scientists work and the interrelationship of physics with other areas of knowledge and its technological applications. This aspect is particularly emphasized in courses intended for distribution.

 

Courses in the department are designed to develop the student’s competence in those fundamental areas of classical and modern physics that have played an important role in the evolution of physics. Familiarity with the art of scientific experimentation is provided through laboratory work that complements the study of theoretical principles. Computation—the third mode of “doing physics”—is emphasized at all levels.

 

The Physics Department prepares the major student in any career where problem-solving skills are required. Popular career options include graduate study in physics, industrial research, secondary school teaching, and professional careers in engineering and medicine. Some of our recent graduates have gone on to graduate studies in the physical sciences. Others have chosen to work in government or industrial laboratories or used their computer skills in the private sector.

 

Physics 100 and 110 are designed to serve the needs of students wishing to take a science course to meet distribution requirements. They do not assume any special mathematics or science preparation.

 

The Physics Major

The major in physics requires the following courses in physics and six auxiliary courses in  related fields.

PHY 111. General Physics I

PHY 112. General Physics II

PHY 201. Electronics

PHY 204. Fundamentals of Modern Physics

PHY 301. Electromagnetism

PHY 304. Classical Mechanics

PHY 401. Selected Experiments

PHY 403. Quantum Physics

CHE 111. General Chemistry I

CHE 112. General Chemistry II

MAT 201. Differential Calculus

MAT 202. Integral Calculus

MAT 203. Multivariable Calculus

MAT 345. Differential Equations

CSI 201. Computer Science I

 

In their junior and senior years, physics majors are required to participate in a weekly seminar (Physics 391/392/491/492).

 

Students planning to major in physics should ideally take Physics 111, 112, and Mathematics 201, 202 in their freshman year. These courses constitute the foundation of the major and should be taken early to ensure timely progress towards graduation. In addition, the student is urged to complete the requirements in chemistry (Chemistry 111, 112) during the first two years. A score of four or better on an Advanced Placement examination may, with the approval of the appropriate academic department, earn course credit toward graduation and make the student eligible to take upper-level courses in the department. Physics majors intending to become certified high school teachers should inform the Education Department as early in their college careers as possible to assure proper scheduling.

 

Senior Capstone Experience

In addition to the required courses listed above, all students must fulfill the Senior Capstone Experience. This is a year-long research project on a theoretical or experimental topic that the student wishes to investigate.

 

The Minor In Physics

The minor in physics requires a total of six semester courses in physics—Physics 111, 112, 201, 204, and two additional ones from among the courses required for the major.
