Rare Element Makes A Good Atomic Clock
A neglected element called lutetium is ideal for making accurate atomic clocks due to its low sensitivity to changes in temperature, scientists say.
For Precision, Two Clocks Are Better Than One
The optical lattice clocks use lasers to create "egg box" structures that contain single atoms, leading to unprecedented precision.
Fixing A Million Year Clock
A new, more accurate value for the half life of 60Fe could be used to fix an atomic clock that measures galactic history.
High-Precision Spectroscopy Paves The Way For Atomic Clocks
Scientists have developed a method of trapping atoms in an optical lattice that could lead to the miniaturization of atomic clocks.
Proposed Ion Clock May Be 100x More Accurate Than Atomic Clock
Scientists are proposing a single-ion clock that would be accurate to 19 decimal places, and 100 times more accurate than than the best atomic clocks available.
