Hello ATS Folks,
Imagine this scenario.....
You are living tens of thousands of years ago, at the dawn of human 'scientific awareness'. There are no clocks/timing devices (mechanical or
otherwise) and very little understanding of Earth time (hours, minutes, seconds) or, indeed, how to measure and record Earth time. All you can see is
that the sun rises in the morning on one horizon and, through the passage of time, it sets on another horizon. And so it goes on. Through continued
observations you may even notice that over a longer passage of time the sun rises and sets slightly further around the horizon. Other than these
observations, you have no real concept of a 'day' as we would understand it.
How then do we measure a 'day' and then divide it in the hour, minute and second based on the sexagesimal (base 60) system? How do we create a
clock based on 1 solar day, i.e. one complete revolution of the Earth? Furthermore, how can we divide the 'solar day' in such a way that the method
can be replicated over time should the knowledge become lost and we have to start all over again?
In consideration of the above challenge, I came up with the following possibility and I would welcome other ideas/solutions.
It is intersting to note that the Ancient Egyptians used a Standard Cubit of 24 digits and also a Royal Cubit of 28 digits. The difference of 4
digits may have been the result of the absence/inclusion of the phalanges of the 2 thumbs - 4 digits in total.
I welcome all constructive comments.
