1. The Mystery of Mathematics
A British man named John Taylor was an amateur in astronomy and mathematics, and also a pyramid enthusiast. He had many amazing things about the pyramids. discovery. He studied the pyramids based on data provided in literature. After calculation, he found that the Great Pyramid of Khufu contained many mathematical principles.
First of all, he noticed that the base corner of the Great Pyramid of Khufu was not 60′ but 51′. It is thus found that the area of ??each wall triangle is equal to the square of its height. In addition, the ratio of the height of the tower to the circumference of the tower base is the ratio of the radius of the earth to the circumference. Therefore, dividing the height of the tower by twice the base can calculate the pi ratio. Taylor believes this ratio is no accident.
He proved that the ancient Egyptians already knew that the earth was round and knew the ratio of the earth's radius to its circumference. Taylor's ideas were supported by the British mathematician Professor Charles Peachsmith.
In 1864, Smith visited the Pyramid of Khufu on the spot. Claims he has discovered more mysteries of the Great Pyramid of Khufu. For example, the height of the tower multiplied by 10 to the 9th power is equal to the distance between the earth and the sun; the circumference of the tower base calculated in a certain unit is exactly the number of days in a year, etc. In other words, the Great Pyramid contains more than just units of length.
Also contains the unit for calculating time. Smith's fieldwork was praised by the Royal Society, and he was awarded the Society's Gold Medal. Later, another Englishman, Ferendzi Petrie, took the measuring instruments that his father had carefully improved over 20 years of hard work to survey and map the Great Pyramid.
During the surveying and mapping, he was surprised to find that the errors in lines, angles, etc. of the Great Pyramid were almost zero. In the length of 350 feet, the deviation was less than 0.25 inches.
But the book written by Petrie after the investigation denied Smith's statement that the circumference of the tower base was equal to the number of days in a year. Petrie's book caused an uproar among scientists. How much knowledge and wisdom the ancient Egyptians embodied in the pyramids remains a mystery.
2. I don’t know who built it
Some people say that the construction of the tower was the work of slaves, but according to archaeologists, there are some Egyptian tombs near the pyramid. According to their tombs, It is inferred from the structure that this is not the tomb of a slave but an ordinary Egyptian, believed to be a worker who died during the construction of the tower. This overturned the theory that towers were built by slaves, and towers were usually built during slack periods and were a general matter.
The Egyptian Ministry of Culture issued a statement on January 10, 2010, saying that an Egyptian archaeological team discovered a group of tombs of pyramid construction workers in the Giza Pyramids area on the outskirts of Cairo, proving that the pyramids were built by workers rather than slaves. . Zahi Hawass, secretary-general of Egypt's Supreme Council of Antiquities, said the tombs were built during the Fourth Dynasty of ancient Egypt, from 2575 BC to 2467 BC.
Similar to the tombs of pyramid builders previously discovered in the area, the distribution of these tombs proves that the pyramids were built by hired workers rather than slaves. "These tombs were built next to the Pharaoh's (i.e. king's) pyramid, indicating that the people buried in the tombs were definitely not slaves," Hawass said, "because it is impossible for slaves' tombs to be built directly next to the Pharaoh's tomb."
To think about this, we need to find the reason from the mother river on which the Egyptians depended for survival: the Nile River. The Nile River is a seasonal river, and its fertility is restored every year due to the silt brought by the floods scouring the river banks. In this way, the water level rises every time the flood comes. During the high season, people had to rest at home. The idle labor force was hired by the state to earn extra money. Building pyramids for the royal family was an extremely glorious thing.

The development and evolution of the pyramids:
The pyramids were the tombs of ancient Egyptian kings. These rulers are known historically as "Pharaohs." The ancient Egyptians' devout belief in gods led them to form a deep-rooted "concept of the afterlife" very early. They even believed that "life is just a short stay, and after death is permanent enjoyment."
Therefore, the Egyptians regarded the underworld as a continuation of earthly life.
Influenced by this "concept of the afterlife", the ancient Egyptians prepared for their afterlife with sincerity and confidence while they were alive. Every wealthy Egyptian was busy preparing tombs for themselves and decorating them with various items in order to obtain eternal life after death.
As for a pharaoh or a noble, he will spend several years, or even decades, building tombs, and also orders craftsmen to continue their boating, hunting, and feasting with tomb murals and wooden models. activities, as well as the tasks that servants should do, etc., so that he can live as comfortably and contentedly after death as he did during life.
According to legend, before the Third Dynasty of ancient Egypt, both princes, ministers and common people were buried in a rectangular tomb made of mud bricks. The ancient Egyptians called it "mastaba". . In ancient Egypt, it was called Piremus, which means high. Later, a smart young man named Imhotep invented a new construction method when designing a tomb for the Egyptian Pharaoh King Djoser.
He used square stones quarried from the mountain instead of mud bricks, and constantly revised the design plan for building the mausoleum, building a six-level trapezoidal pyramid - this is the structure of the pyramid we see. prototype.
In ancient Egyptian literature, the pyramid was layered in a trapezoidal shape, so it was also called a hierarchical pyramid. This is a tall pyramidal building with a square base and a triangle on each side. It looks like the Chinese character "金", so we call it "pyramid". The tower-style mausoleum designed by Imhotep was the first stone mausoleum in Egyptian history.
The Zoser Pyramid at Saqqara is a typical representative of this type of pyramid. It was built in 2750 BC and was the first huge building made entirely of stone in Egyptian history.
