During the speakers' seminar, which is organized biweekly at the Institute for Theoretical Physics, international experts will present contemporary research. The colloquium has to be attended at least 18 times in order to pass. Even though the colloquium speakers are well aware that master students make up a considerable fraction of their audience, the level of the colloquium is often unavoidably high. In order to optimise the student's benefit and understanding of the colloquia, a preparatory presentation by an ITP staff member will (often) be organised in which background information, history of the subject, or other relevant material will be informally discussed with the students. Attending this meeting, which will be scheduled at 15.00h just prior to the colloquium in room MG 401, is highly recommended but not compulsory. More details will be announced by email in due time.
