About Physics and Astronomy

We place great emphasis on maintaining a department atmosphere that invites the active engagement of students like you. Our small classes and ability to create one-on-one working and researching relationships with students succeed in achieving just such an atmosphere.

The average class size in our department is around 15, and we graduate an average of 17 majors per year. These small numbers allow individualized development and direct access to our faculty members, but without sacrificing access to world-class research opportunities or facilities.

Physics or astronomy majors are a diverse group, and the flexibility of the majors allows them to pursue their varied academic interests. In addition to the information in the course catalogue, there is a wealth of information and advice regarding how to tailor your schedule to your particular interests.
