Topic	Einstein's theory of relativity/ first steps to ART
	Albert Einstein's theory of relativity has been on my list for many years and is one of the subjects I would like to understand better. The demanding mathematical approaches have been a hurdle to gain a better understanding of this part of physics for years. This Corona winter I followed a lecture at the University of Heidelberg as a guest auditor in the Faculty of Physics and Astronomy. Dr. Markus Pössel made it easier for me to get started with this topic based on his presentation.
Presentation	Based on the lecture documents, a 35-page description of the special and general theory of relativity was created. In view of the complexity, these can only be the first introductory steps.
Data	No further files are necessary here - the theory is presented in detail in the report above. A small list of further literature can be found in the appendix to the report.
Notes	Sorry - this documentation is only available in German language. April 2021
