Scientists take an atomic clock on the road and use it to measure the height of a mountain

Most of us think of time as a way to measure things like the length of our days and the span of our lives. But if you had access to a pair of extremely high-precision clocks, you could use time in a ...

Gravity measured for first time using a portable ‘atomic clock’

Scientists have used a portable “atomic clock” to measure gravity for the first time. The device makes use of small changes in the flow of time at different altitudes to measure the Earth’s gravity.
