Atomic clockCaesium atomic clocks operate by exposing caesium atoms to microwaves until they start to vibrate at one of their resonant frequencies. By measuring this frequency, which is an unchanging property of matter, a time measure can be established. Caesium atomic clocks are very stable, and accuracies of 1 second in 1.4 million years have been reported.
