The ticking of the clock. Wherever we turn , we all see - on the right! But have you ever wondered why you turn right ? Turning to the left or what is the problem ? If not , what exactly causes the clock to turn to the right ? The oldest clocks , however, did not have a spinning wheel. Yes , the sundial is the oldest clock in the world. But this sundial was also of many kinds. The oldest sundial is said to be the Egyptian obelisk. It is believed that the Egyptians learned to make this watch three and a half thousand years before the birth of Christ. Another such watch is called 'Shadow Clock'. It was built by the Babylonians a thousand and a half years before the birth of Christ . Now , in these sundials, time was seen by looking at the shadow of the sun. That is , the time-indicating thorn or bar would be fixed. The time was calculated by seeing the change of the shadow of the thorn in the light of the sun. And again , these would mean that you have to spend for these processes. There is no harm in seeing shadows. This type of clock , which means that the hands of the clock tell the time , the clock was first made in the 13th century. But then these watches did not become so popular. What will happen , there is still no need to look at the time of the people. Seeing the sun, people would understand that now it is morning or noon , afternoon or evening. There was no need to worry more about time. About 400 years later , in the 18th century, when factories began to settle down , people began to need to look at specific times. You have to go to the factory at a certain time , have lunch at a certain time and go to work again , there will be a holiday at a certain time , that is the rule of the factory! Then everyone needed that forked watch , so that everyone could do everything on time. As a result, watches became very popular. Now let's make an account. The region in which the old clocks were made , Egypt and Babylon — these are all in the same region. Other sundials, however, were made in close proximity to that area. That is , the region between Asia and Europe, what is now called the Middle East in Western terms. Egypt-Iraq-Iran-Turkey in that region. Most of the famous ancient civilizations of the world were formed in this region. Such as the Egyptian civilization of Egypt , the Mesopotamian civilization of Iraq , the Persian civilization of Iran , the Greek and Troy civilization of Turkey. Mesopotamian civilization again has four divisions — Sumerian civilization , Babylonian civilization , Assyrian civilization, and Chaldean civilization. Due to the geographical location of the region, the shadow of the sundial would move continuously from west to east with the passage of time. That is to say , as the day rolled towards night , the shadow also moved from west to east. From there came the matter of the clockwise direction. Accordingly, the hands of the clock go from west to east. Now the question is , what is the relationship between left and right with west-east ? Now let's sit down with a map. There is a directional mark at the top of the map. Next to it is written N or North. I mean , the top of the map is North , which is called North in Bengali. And the lower side is south. Then fall west on the left and east on the right. This is why the hands of the clock go from left to right. I mean , in fact, it doesn't go from left to right , it should go from west to east.
