Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability.
A proposed new time-keeping system could make atomic clocks look positively erratic, staying accurate to one twentieth of a second over 14 billion years - the age of the universe.
A caesium fountain clock that keeps the United Kingdom's atomic time is now the most accurate long-term timekeeper in the world, according to a new evaluation - twice as accurate as was previously believed.
Well, it's certainly annoying when your wristwatch doesn't keep perfect time. But there's a solution - yes, the world's smallest atomic clock is now available commercially, for only $1,500.
