## PHYSICS 205: Senior Thesis Research

Long-term experimental or theoretical project and thesis in Physics under supervision of a faculty member. Planning of the thesis project is recommended to begin as early as middle of the junior year. Successful completion of a senior thesis requires a minimum of 3 units for a letter grade completed during the senior year, along with the other formal thesis and physics major requirements. Students doing research for credit prior to senior year should sign up for
Physics 190. Prerequisites: superior work as an undergraduate Physics major and approval of the thesis application.
