The Process Of Identifying Time
Why and how did we get to a process for identifying “time” ??
As a civilisation in the 21st Century we still have a problem with our understanding of “time”. In order to help me to get my mind around the problem of “time” I set about putting my thoughts down on paper. OK, in an electronic file. I hope these thoughts may help you.
Before life on earth there was no eyes to translate the suns reflected radio waves into light and dark. However, as the earth rotated, one half of the earth was bathed in radio waves and one half was not. On the half of the earth that was bathed with radio waves there were obstacles, in the way of radio waves, which caused a reduction in the density of the radio waves and caused a radio wave shadow. This scenario was maintained for billions of years.
With each rotation of the World around its own axis and, also, its rotation around the Suns axis, life, as we understand it, began to take hold. But it would take billions of revolutions of the earth around the Suns axis and even more billions of revolutions around its own axis before the first eye developed in nature and the first eye was to develop in primitive life. We can say that these two rotational movements were made and could be measured as total radians completed, relative to each other, but without any other yardstick the “time” elapsed to make the total radians relative to each other could not be determined. There was no intelligent life and the relevance of “time” meant nothing at that moment.
However, the first “seeing eye”, by a miracle of evolution, developed in a very primitive life form, in the seas, and very much later, the primitive life form developed and, in time, left the sea and developed into mankind and, of course, with a continuous development of eye site. Accordingly, the first humans were able to appreciate darkness and light as the World revolved around its own axis. They could also appreciate that shadows were formed which changed with the angle that the sun made with the earth.
Over thousands of years the recording of day and night as a way of measuring our position in a day and, then, the use of Sun dials soon became inadequate and this led to Egyptian scholars, of the day, breaking the earth’s rotation into 24 sectors. The same scholars had worked out that the earth rotated +/-365 times in one cycle around the sun, to basically arrive at the same position. The scholars then broke the 24 sectors into much small fractions. Accordingly, the scholars introduced the hour, the minute; and the second into our understanding. These basic elements were named units of “time”.
With the continued development of man’s understanding of the World, civilisation became used to using the terms “distance”, “height” and “width”. This introduced the understanding of 2 dimensional and then 3 dimensional configurations of matter on the earth and in space. Also, tied into the use of 2 and 3 dimensions, a fourth dimension, of “time”, was introduced through the work of the scholars. Taking a simple example a bus going from the bottom of a valley to the top will move through a horizontal distance x, through a depth distance z and through a height distance Y. This movement does not take place instantaneously but over the course of a period we understand as “time”. We understand it in hours, minutes and seconds but it could be equally understood as radians through which the earth has rotated whilst the bus did the journey. Also in the same period is could be understood as the fraction of a radian that has been made of the earth around the sun. There two measured radians would be completely different but a valid means of measuring the period elapsed.
This would infer that we are measuring a change (of position, of energy) by reference to a distance travelled not as a position relative to the Sun (To Part 6)
