Grave of Werner Braunbek, Bergfriedhof Tübingen

MAR 28 2011

The grave of the physicist Werner Braunbek in the Bergfriedhof in Tübingen. Braunbek proved in 1939 that Earnshaw's theorem does not forbid stable levitation if a material with permeability below one - a diamagnet - is involved, which is the theoretical licence for every levitation image later in this story.
