Chinese researchers have built the most precise portable atomic clock ever, and it’s small enough to move around easily. 

 

It's about the size of a refrigerator and is made to handle rough conditions while staying super accurate—within one-fifth of a quadrillionth of a second!

This cutting-edge clock is a game-changer for military operations like radar coordination and electronic warfare. 

 

It works on its own with very little maintenance, showing a big leap in China's tech power.
