She writes in Psychology Today that those who were better at clock-checking were therefore “less reliant on their potentially flawed internal timekeeper”.
These are the timekeepers of the universe, the clocks of the cosmos, mechanistically ticking away with such certainty that we can use them to measure time across vast stretches of the universe.
It was found that the earliest ancient timekeepers were mainly invented and used in Mesopotamia, where the water clock was introduced from, as well as in North Africa, especially in the area of ancient Egypt.
So, now I'd like to introduce you to some of the most well-known ancient timekeepers, as well as the disadvantages of them, for which they were replaced by various new forms of clocks that were used afterwards.
