Physics

Physics is the study of an enormous span of natural phenomena ranging from the large scale involvement of galaxies to the the submicroscopic motion of atoms and nuclei. A major in physics at St. Mary's University prepares students with a broad based view of science, as well as the analytical tools necessary to tackle problems in many different fields. Physics is an intensive course of study that emphasizes analytical and problem solving skills. Students have the opportunity to acquire a degree either in physics or applied physics.

The Bachelor of Arts in physics is usually chosen by students who wish to teach high school physics. The applied physics degree has an option in computer science or electrical engineering. Applied physics is a Bachelor of Science degree plan that provides an instructional base in physics, engineering, mathematics and computer applications. It prepares students to enter today's high technology marketplace upon graduation. Along with technical courses, students in the program benefit from liberal arts courses in English, social science, philosophy, theology, speech, foreign language and fine arts.

All courses serving as prerequisites in the School of Science, Engineering and Technology must be completed with a “C” or better in order to advance to the next sequenced course.
