Clockmakers at the National Institute of Standards and Technology (NIST) have developed a more accurate atomic clock, one based on strontium, that ticks 430 trillion times per second. This new clock is 40000 times more accurate than the current-gen cesium clocks which lose a totally unacceptable 1 second in 20 million years.
Good work – but what the world needs right now are more and better atomic clock jokes.
