One of the most important skills of any physicist, second only to the ability to do research itself, is to communicate both the results and the methods of that research to a variety of audiences: students, peers, senior researchers, and to a lesser extent, the general public. All of these groups require their own unique approach, and it is to the first two that the student seminars in the theoretical physics department at Imperial are aimed. The speakers are PhD students, the audience consists of PhD and MSc students in comparable proportions. This is a pedagogical experience for all involved, albeit in different ways.
