General Theory of Relativity on the Computer - An Interactive Lecture — •Matthias Hanauske — Institut für Theoretische Physik, Max-von-Laue-Straße 1 — Frankfurt Institute for Advanced Studies, Ruth-Moufang-Straße 1, Frankfurt, Germany

The concept, the content and the implementation of an interactive lecture held at the Goethe University in SS2016 will be discussed in this talk. The main focus of the course is general relativity theory as well as the imparting of special programming knowledge, whereby the lecture took place in the PC pool of the institute and the students should apply the learned concepts directly during the lecture. In the first part of the course, students learn the use of computer algebra systems (Maple and Mathematica). Various applications of the Einstein and geodetic equations were implemented in Maple, quasi-analytic calculations were carried out and corresponding solutions were calculated and visualized. The second part of the course focused on the numerical calculation of neutron stars and white dwarfs using a C/C++ program. In addition, the basic concepts of parallel programming were introduced and an MPI and OpenMP version of these programs where created. In the third part of the course, time-dependent numerical simulations of GR were carried out using the Einstein Toolkit. (For more information, see http://fias.uni-frankfurt.de/~hanauske/VARTC/ )
