Summary
[edit]| Description |
Deutsch: Für die einheitliche Definition der Sekunde galt früher die Bahnbewegung der Erde um die Sonne als Grundlage. Ab 1967 wurde die Sekunde mithilfe der Cäsium-Atomuhr definiert.
English: The orbital movement of the earth around the sun used to be the basis for the uniform definition of the second. From 1967, the second was defined using the cesium atomic clock. |
