Prof. König was a student of the brilliant scientist Schumann. Prof. Schumann was the namesake of the Schumann frequency, the frequency at which the Earth has its rhythm, which exactly corresponds to the frequency of the human heart. The work of the Munich professor "Invisible Environment" was a standard reference for thousands of students. Today's insights of modern physics would not have been possible without his contributions. The large-format work, which sold tens of thousands of copies during its 10 years of availability, is now being released in an edition that is affordable for anyone interested. Prof. König stands in the direct tradition of such brilliant minds as Nikola Tesla and Winfried Otto Schumann. In his experiments on wireless energy transmission without energy loss, Tesla generated enormous electrical voltages with his experimental setups.
