# BA in Physics & Computer Science

The joint Physics & Computer Science major at Boston University allows students to develop a fundamental knowledge of physics and computer science that they can apply in many fields. A curriculum that carefully combines courses in the two disciplines provides the students with an integrated view of the application of basic physics concepts to computer science and of computer science ideas to the study of physical phenomena. This integration is becoming ever more important as topics such as quantum computing and machine learning are the focus of major industrial developments. The student’s learning takes place in two departments that maintain a rigorous research program in their respective disciplines and will prepare them for a successful career. Physics & Computer Science majors should have advisors in both the Physics department and the Computer Science department.

## Learning Outcomes

Students completing the BA in Physics & Computer Science will have:

- Knowledge of fundamental concepts in physics and computer science.
- Knowledge of the application of advanced mathematical and computational methods to problems in physics and other fields.
- Programming and software engineering skills.
- Combined theoretical and technical skills to use on real-world applications.

## Requirements

All BU undergraduate students, including both entering first-year and transfer students, will pursue coursework in the BU Hub, the University’s general education program that is integrated into the entire undergraduate experience. BU Hub requirements can be satisfied in a number of ways, including coursework in and beyond the major as well as through cocurricular activities. Students majoring in Physics & Computer Science will ordinarily, through coursework in the major, satisfy BU Hub requirements in Quantitative Reasoning 1 and 2, Scientific Inquiry 1 and 2, two units of Critical Thinking, two units of Teamwork and Collaboration, and one unit of Digital Literacy. Remaining BU Hub requirements will be satisfied by selecting from a wide range of available courses outside the major or, in some cases, cocurricular experiences.

Unless otherwise noted, all required courses are 4 credit hours.
