Earth rotation lecture for pupils

On 5 October 2012, Johannes Böhm gave a presentation at the Gymnasium Zwettl about Earth rotation and how it can be observed. He also provided information about studying "Vermessung und Geoinformation" at the Vienna University of Technology. It was a "home game" for him because he went there to school from 1982 to 1990. Also on the picture are Manuela (his wife), a pupil, and his brother Reinhard who teaches Mathematics and Geometry at the Gymnasium Zwettl.
