And if you watched my previous video you Know that every time you use GPS, you're actually measuring time.

如果你看过我之前的视频，你就知道每次你使用全球定位系统，你实际上都是在测量时间。

But you're measuring a longer time than Bob is.

但是你测量的时间比 Bob 多。

We use the numbers to quantify the world around us, like measuring time; also for communication, like telling person our age.

我们用数字来量化我们周围的世界，比如测量时间；也会用它们来进行交流，比如告诉别人我们的年龄。

B. New ways of measuring time can help to control Earth systems.

B. 测量时间的新方法有助于控制地球系统。

And tracking a spacecraft as it travels through deep space is fundamentally a problem of measuring time.

当航天器穿越深空时对其进行跟踪从根本上说是一个测量时间的问题。

By then the rapid pace of industrialization in the Unites States meant that measuring time had become essential.

到那时，美国工业化的快速步伐意味着测量时间变得必不可少。

Some atoms can oscillate over nine billion times per second, giving atomic clocks an unparalleled resolution for measuring time.

一些原子每秒可以振荡超过 90 亿次，使原子钟具有无与伦比的测量时间分辨率。

And you need to stop the environment from accidentally measuring your qubits all the time and collapsing those delicate quantum states.

而且你需要阻止环境一直意外地测量你的量子比特并破坏那些脆弱的量子态。

Modern radar is highly sophisticated but it largely relies on emitting a signal. By measuring the time taken for the reflected signal to return it is possible to work out the position of an aircraft.

现代雷达极其复杂，但主要还是靠自己发出信号。通过测量被反射信号返回雷达所需的时间，就有可能计算出飞行器的位置。

They are more excited about having two independent ways of measuring time: atomic clocks, which depend solely on the electromagnetic force governing the electrons' movement; and nuclear clocks, which also obey the strong nuclear force.

令他们更为兴奋的是， 有两种独立的计时方式：原子钟，仅依赖于控制电子运动的电磁力；核钟， 也遵循​​强核力。
