Finding the right element

Before timekeeping could go fully atomic, countries had to decide which atom would work best. 

At the Thirteenth General Conference of the International Committee for Weights and Measures in 1967, researchers decided on Cesium-133.

  • It maintained a reliably measurable quantum spin 
  • It could easily vaporise.
