Time and Navigation from the National Air and Space Museum explores the surprising connection between time and place—if you want to know where you are, you need an accurate clock. And the Cooper ...

Seventy-eight years ago, scientists created a unique sort of timepiece — named the Doomsday Clock — as a symbolic attempt to gauge how close humanity is to destroying the world. On Tuesday ...

These optical clocks are still being assessed, but already now, some are 100 times more accurate than cesium clocks. They will therefore become the future basis for the worldwide definition of the ...

IN these days of accurate clocks and watches no one thinks of using a sun dial to tell the time of day. At best such an instrument can be right but four times a year, and in many places it can ...

These optical clocks are still in the testing phase, but some of them are already a hundred times more accurate. This is why they are to become the basis for the global definition of seconds in the ...
