During the Summer School Particles, Strings & Cosmology at Universität Hamburg, participating students had the opportunity to learn from leading scientists in a unique research environment. Participants examined theoretical concepts to deepen their knowledge in the above named fields and discussed advanced research questions with different peer groups. The physics program was complemented by sessions on German culture and history - topics were discussed and taught on field trips and during excursions. A language course and extracurricular activities, such as a day trip to Berlin, have complemented the program.
