| Title: |
Time & Frequency; Atomic Clocks; NIST F1 (2008) |
| Description: |
The clock uses a fountain-like movement of cesium atoms to determine the length of the second so accurately that--if it were to run continuously--it would neither lose nor gain one second in 80 million years.
Learn more about how the clock works and view an animation of the clock in action.
