Ytterbium atomic clocks set record for stability
A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology has set a new record for stability. The clocks act like 21st-century pendulums or metronomes that could swing back and forth with perfect timing for a period comparable to the age of the universe.
