Episode: Mathematik, die letzte Freiheit der Gedanken

Die Knotentheorie gehört zur Hohen Schule der theoretischen Mathematik. Die Kunst besteht darin, zu beweisen, dass bestimmte Knoten auf ewig unlösbar sind. Diese Fälle unterscheiden sich von komplizierten Verwicklungen, die nur unlösbar aussehen. Ein solcher Beweis benötigt einen Tag oder hundert Jahre. Einen Vorteil hat derjenige, der den Quoten-Zoo respektiert. Ein Zerhauen von Gordischen Knoten ist in der Mathematik verboten und im Nahen Osten vergeblich. Der Mathematiker Priv.-Doz. Dr. Peter Schauenburg berichtet.
