In Masters of Science I, Daan Tamminga, a master student myself, talk to master students at the Faculty of Science about their study program and their master thesis from a personal, student-framed, perspective. In this episode I will talk to Geoff Allen, student History and Philosophy of Science. Among other things we will discuss the broadness of the program, how to deal with this broadness, how to find a thesis and how Geoff planned and did his thesis on the philosophy of perception.
