[关键句]Even advanced physics can't decisively tell us what time is, because the answer depends on the question you're asking.(第一段最后一句) 译文:即使是高等物理也不能明确地告诉我们时间是什么,因为答案取决于你提出的 问题。 【解题思路】根据第一段内容尤其是关键句可知,第一段主要介绍了每个人...
Today’s most accurate atomic clock would take around 30 billion years to lose even one second.
An atomic clock is the clock which uses atomic frequencies of atoms ( particularly caesium -133) as its resonator. They are the most precise time measuring instruments so far. Show More | ShareSaveClass 11PHYSICSDIMENSION AND MEASUREMENT
An atomic clock is a precise timekeeping device that relies on the known frequency standard of an element to keep time. Atomic...

so UT1 deviates increasingly from International Atomic Time (TAI), the second fundament of UTC, which is measured by highly preciseatomic clocks. Before the difference between the UT1 and UTC reaches 0.9 seconds, aleap secondis added to UTC, so our clocks reflect the speed of the Earth's ...

根据第一段“Today’s state-of-the-art atomic (原子的) clocks have proven Einstein right. Even advanced physics can’t decisively tell us what time is, because the answer depends on the question you’re asking.(如今最先进的原子钟已经证明爱因斯坦是对的。即使是高级物理学也不能明确地告诉我们...
Today, though there are different types of atomic clocks, the principle behind all of them remains the same. The major difference is associated with the element used and the means of detecting when the energy level changes. The various types of atomic clocks include: Cesium atomic clocks employ...
