How Do We Measure Seconds at Bernadette Preusser blog

How Do We Measure Seconds. The earth's rotation around itself (one rotation around earth's own axis) doesn't take exactly 24 hours. A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. These clocks produce electromagnetic radiation, such as microwaves, that atoms in the clock absorb. We can measure time intervals — the duration between two events — most accurately with atomic clocks. So the original definition of a “second” is 1/86400th of a day. The second is currently defined using cesium atoms, which absorb and emit microwave radiation with a specific frequency. With 24 hours in a day, 60 minutes per hour, and 60 seconds per minute, there are 86,400 seconds in a day. Atomic clocks count 9,192,631,770 of those microwave oscillations,. Then again to get 60 seconds. Accurately determining what that means and how. It off by some seconds which becomes. So… we know that the si system measures a second in terms of the oscillations of a cesium 133 atom, but researchers in germany. A second is 1/86,400 of the time that it takes the earth to rotate once on its axis. The base unit of time in the international system.

Here’s why we measure time in seconds (and why seconds are the length
