I hope it can fly with us to Canary Islands.
Recently I was reading a novel describing the encounter of Humboldt and Gauss. La medición del Mundo of Daniel Kelhmann "Die Vermessung der Welt".
The coin has travelled much more than Gauss in his real life. But he measures a lot of things without go out home.
Gracias y Saludos.
