Improvements in clocks are setting the stage for a redefinition of the second. This is an Inside Science story. (Inside Science) -- Earlier this year, in a nondescript lab at the National Institute of ...

Researchers at the U.S. National Institute of Standards & Technology (NIST) say they have created the most accurate atomic clock to date — one that can measure time down to the 19th decimal place.

This particular clock is technically an ion clock, which is different from the more common atomic clocks that are based on measuring the resonant frequencies of a single cesium atom to regulate time ...

Considering that 90% of American adults own mobile phones, the practice of interrupting strangers to inquire about the time has almost completely disappeared. Since these devices are so prolific in ...
