Physicists unveil the most accurate atomic clock ever ‪—‬ and it could literally redefine the second
Physicists have used radioactive lutetium to create what they say is the most accurate atomic clock ever, keeping time perfectly up to 19 decimal places.
As the world considers redefining the precise length of a second, Singapore’s Centre for Quantum Technologies has delivered a ...
