Measuring time, the origin of the body clock

Door San Daniel gepubliceerd in Verhalen en Poëzie

Time controls man, who is guided by it. Two parties make an appointment and meet each other on time. They are on time. Time passes and does not return, we can only have the time pass again in our memory. Time is a measurement of the passing of moments. Yet it is not entirely an agreement between people. In the beginning, time as a biological and external instrument guided our lives to protect us. This is how the body clock works, which also causes "jet lag" until the body gets into pace again.


Ticking away the moments that make up a dull day

Fritter and waste the hours in an offhand way

The sun is the same in a relative way but we are older

shorter of breath, one day closer to death

Pink Floyd "time" (dark side of the moon)



Why does a bird lay an egg?
Birds nest from instinct, it is not a process that originates in planning. In May all birds lay an egg is a well-known saying. How come? Eggs are laid and hatched in each individual country without being in contact with other bird species. The bird's body clock responds to a gland that is situated behind the eye and extends into the pituitary gland, in the brain. If more or stronger light comes through the eye, the body clock converts a switch via the gland in the pituitary gland. The activated part is responsible for the production of a hormone that makes a bird brood. The body is then prepared by the hormone to produce an egg. The bird then follows a series of instinctive steps, a nest is made in a safe place and when that is ready an egg is laid. The dish is calcareous and works as a heat container. The bird likes to sit on the warm egg. The egg hatches after 21 days. Not on the 20th or 22nd day but after 21 days.

Man as the god of abstraction in the animal kingdom

Since the beginning of time there have been concepts that have been recorded by everyone. There has always been a day and a night. The sun came up or there was a moon with stars. Men had a father and mother and brothers or sisters. In comparative linguistics you will find these concepts in any original language. People are the gods of abstraction in the animal kingdom. They want to control or classify what they see or indicate shape or describe or count. The ten-fold system was probably created because people have 10 fingers. If there were also a way to record the number of sunrises or sunsets, an appointment could be made in time. For example, I will see you after the 6th sunrise, but miscounting is done quickly. The first known time recorder makes its appearance.



What have you got on your notchstick

You are prosperous and have many sheep. You also have many shepherds who go out with their herds, you agree: "in 7 days we will meet again at the old well". From there we move on together, as not to be an easy prey for raiders, to the next place You have devised a system that brings everyone together on the same day. Everyone gets a cut branch or stick or a piece of wood. 'This is a notch stick', you say while you hold it up. Every time the sun rises you carve a groove in this wood. If there are 6 then you have to be at the well the next day. It works fine, the first tool to keep track of time has been invented. Everyone is at the well on the 7 th day. If you do not keep track of time, the days slip.

A clock told the time whether it was exact or not

If an Egyptian priest was charged with religious acts that had to take place exactly at the same time every day, there must have been an instrument to help him with that. That instrument existed it was called the water clock.




The water clock let through a quantity of water within a certain time. You filled a reservoir and slowly it emptied. Now you could start your worship service, incantations or whatever at the same time each day. Later there was refinement that no longer needed to be refilled, the sundial. It was dependent on the sun again and it didn't help you at night. If you can measure days and time, then you are well on your way to an organized society. After a while the priest caste notices that there is a regularity in the rising and waning of the moon. They know after a few notch sticks that it is a full moon every 28 days.



Now full moons could be predicted. That gave them respect. Now if they could also "predict" which meteorite will be visible on a certain day with the same regularity, because everything orbits around the sun and therefore also passes us, then they have become astronomers as well. You can take advantage of that. If you ask for a favor with Pharaoh, for example a new temple, knowing that tomorrow a meteorite spectacle will take place that takes place once every 5 years and as a condition you state that the Pharaoh should judge favorably if the Gods give a sign tomorrow , then you are a sure winner if the night after is filled with fiery stripes. How could the Pharaoh ignore such a sign and the priesercaste rises enormously.
Math is Math and a circle has 360 degrees

The Babylonian civilization in Mesopotamia was founded 1800 years before Christ. They had a priestly caste who was very adept at making astronomical calculations and orbiting speeds of the moon or earth. Mathematics is more a philosophical than an arithmetic study. You can measure objects that are difficult to measure with mathematics. You can provide "proof" by formulating theorems. Calculate unknowns. 3 degree comparisons.




The Babylonians calculated the circumference of the earth and the orbit of the earth returned to the same position, compared to constellations that were then seen in the same place. So they managed to calculate a year. They did very well with their limited resources. They believed that a solar rotation or a year lasted 360 days. They found that a circle was a form of perfection, not a beginning or an end, but also the cyclical aspect of a snake that bites its own tail, the alpha and the omega.

Yup they were out unfortunately. There we are, we know that a year has more days. Emperor Augustus corrected that later and with the introduction of a leap the quarter day difference in circulation per four years was corrected in the month of February. We are left with something geometric that says that a circle has 360 degrees by analogy with the Earth's orbit. That really ought to confuse you as a child? You learn the metric system at school, everything multiples of 10: centimeter, decimeter, meter. 100% is everything from something, there is no more, but a circle has 360 degrees thanks to the cyclical aspect of the Babylonians. that had quite a few consequences in geometry ..



If a circle had been metric, which is just an agreement, a circle would have been 100 degrees instead of 360 and a rectangle, a quarter of a circle, 25 degrees instead of 90 degrees. It would have made everything so much more logical for junior highschool students.

Back to time

The division of 12 hours into a part of the day was established by analogy with the 12 months. If you multiply 12 by 2, you will have the 24-hour period. If you multiply it by 5 then you have the hour with its 60 minutes. if you take half, the half hour that corresponds to 5 X 6 = 30 minutes, you multiply 30 by 12, then you come back to 360 and the circle is round again. Everything is based on an agreements. We could have agreed just as well that we would maintain a decimal clock. A whole day 10 long hours, half a day 5 long hours. It is about time measurement and not about methodology.



 Body clock and time measurement

Scientists at Cambridge think that the mechanism that controls the duration of our sleep and that causes jet lag when changing location, stems from a time prior to our time schedules and measurements. The scientists have identified an enzyme that is responsible for our sense of time and that occurs in humans, mice, fruit flies, plants up to 1 cell life. A sequence analysis based on genetic research shows that the enzyme first appeared 2 and half billion years ago. That coincides with the oxygen-forming process from that time that finally created our atmosphere. A process where photosynthesis converts carbon dioxide into oxygen, through plants. The enzyme is known as peroxiredoxin. Just as the bird reacted to more light and therefore switched to egg production, this enzyme reacts to too much oxygen accumulation.  




The formation of the atmosphere went in stages and until there was a unity in atmosphere composition, there were peaks where oxygen accumulated. Too much oxygen damages organisms. Photosynthesis works through the daytime as the conversion process needs sunlight. In those times the peaks of oxygen fell. Today, the enzyme works as an integrated body clock, on a 24-hour basis. Even if you are completely isolated or in the dark.

It was a protection mechanism that led to inactivity during oxygen peaks. The species that was blessed with the PRX enzyme was better adapted and therefore had better survival chances. Better chances than the organisms where it did not register that oxygen was too saturated.

The enzyme worked 2 and half billion years ago on a different format than the current 24-hour format. That's because the earth then had a faster rotation speed and a day "only" lasted 11 hours. The clock then and our body clock now adjusts quickly. It is a survival mechanism. If one travels far away to a different time zone, then that clock needs to be adjusted. The body is tired out of habit, but it is still day because of the distance traveled: "Jetlag" After a few days the clock adjusts itself again and the traveler is again in tune with his or her body.

What does San Daniel think of all of this? Heaven forbid, a day of 11 o'clock! Then I'd get absolutely nothing done anymore.
