    Project Guidelines


    The project is worth 40% of the grade. You should work in teams of 3-4. We encourage cross-disciplinary teams, since ideally a project should address both CS and Physics aspects of the question being studied. At the end of the semester each team will submit a project report, as well as give a 15-20 minute oral presentation.

    Here are a few suggestions of broad topics for projects. We will add to this list, and you should feel free to suggest any topic that you are interested in. When you are ready, please email the course instructors the composition of your team, the topic, and a brief description. You are also encouraged to discuss your topic in person with any of the faculty.
