Der Regenwald des Amazonas, Energienetze und Zellen im menschlichen Körper teilen alle eine beunruhigende Eigenschaft: Sie haben mehrere stabile Zustände. Wenn der weltgrößte tropische Wald bei fortgesetztem Klimawandel plötzlich schrumpft, die Energieversorgung kurzfristig zusammenbricht, oder wenn gesunde Zellen zu Krebszellen werden, so ist das ein Übergang von einem stabilen Zustand in einen anderen - und offenkundig unerwünschten. So erfasst es die Wissenschaft komplexer Systeme. Weil diese Übergänge typischerweise Ergebnis einer äußeren Störung sind, ist es wichtig zu wissen, wie stabil der erwünschte Zustand ist. Überraschenderweise hat diese Frage bislang wenig Aufmerksamkeit erhalten.
