Stock Photo - 22 April 2020, Saxony-Anhalt, Magdeburg: Mathias Magdowski, research associate of the Faculty of Electrical Engineering and Information Technology at Otto-von-Guericke University, sits alone in a laboratory of the institute and records a teaching video for the master course ""Analysis and Calculation of Electrical Systems"". Due to the spread of the corona virus, students are currently not allowed to attend classroom lectures. Therefore the lessons are now recorded and published on the internet. The summer semester 2020 will be mostly online. Presence lectures in laboratories or practical courses are not permitted again until 4 May at the earliest, but then they are linked to distance and hygiene requirements.
