Our majors find the Senior These to be one of the most challenging experiences at Haverford, but also the most satisfying. With guidance from their faculty mentors, students write a paper, typically 25-50 pages long including figures and references, aimed at a general audience of physicists. Frequently, this leads to a publication in a peer-reviewed journal.
