atomic clock

USA- Experts developed an atomic clock that can calculate time about 1,000 times more accurately than most clocks on ships today.

The new atomic lattice clock broke the record for accuracy by missing just one second after 39.15 billion years.

China's optical atomic clocks are designed to be accurate to one billionth of a billionth of a second on Earth, or just one second after 30 billion years.

The Deep Space atomic clock was launched in June and finally activated officially at the end of August.

According to the Los Angeles Times, scientists took a big step last week in using the time to measure sea level and above.

2016 is longer than usual because it is a leap year, but because it will be added 1 second more than usual.

According to calculations, China's latest cold atomic clock is only a second later ... 1 billion years.

Because the speed of the Earth's rotation is slowing down due to the gravitational influence of the Moon, we have to add a second to the atomic clocks to avoid time being deviated.

Time experts around the world will add one second at the last minute of June 30. Sun time is the time scale that 12 o'clock noon is when the sun is in the highest position in the

Some scientists propose to replace the atomic clock with a nuclear clock, because the nuclear clock only runs one-thirds of a second within 14 billion years - the time equivalent
