In this century, with more and more extensive observation and research activities on flying saucers, some people even associate the mysterious pyramids with the aliens on the unpredictable flying saucers. They believe that thousands of years ago, humans could not have the ability to build pyramids, and only aliens could have them. After calculation, they also found that the earth is divided into two hemispheres by the meridian of pyramid of khufu, a suburb of Cairo, the eastern hemisphere and the western hemisphere, and their land areas are equal. This "coincidence" is probably the intention of aliens to choose the site of pyramid construction.

However, a French chemist named David Duvis put forward a brand-new view on the construction of the pyramids. He thinks that the huge stones for building pyramids are not natural, but artificially poured. He got five small stones from the Egyptian pyramid of khufu from an archaeologist and tested them one by one. Unexpectedly, the test results prove that these stones are made of shell-like limestone. Although archaeology has proved that human beings have mastered the technology of making concrete thousands of years ago, it is hard to believe that these shells and limestone are so difficult to distinguish from granite.

David Dewey speculated that the ancient Egyptians used the method of "breaking the whole into parts" when building the pyramids, that is, putting the mixed concrete into a basket and carrying it on or on the back of the pyramid being built. In this way, as long as you master certain skills, you can pour out the huge stones piece by piece and add towers layer by layer. This is "labor-saving" and labor-saving. According to his estimation, there were only 1 500 people working on the construction site at that time, not 65,438+10,000 people in each batch as Herodotus said.

More unexpectedly, the French scientist also found an inch-long human hair in the stone. This strand of hair may be a testimony to their hard work and brilliant wisdom. But these statements are still some guesses.

But in any case, the construction of the pyramids must have concentrated all the wisdom of the ancient Egyptians at that time, because there must be many problems to be solved. But all these problems have been solved. The pyramids have been built and stood for more than 4000 years, which is a miracle in itself. Therefore, it can be said that the pyramids are the crystallization of the wisdom of the ancient Egyptian people and the symbol of ancient Egyptian civilization.

Some people don't believe that simple cooperation can create miracles. They don't believe that humans on earth will create miracles like pyramids themselves, saying that they are the creation of whispers. This is obviously incorrect and does not help people to explore their own history and know their own abilities.

According to legend, before the third dynasty in ancient Egypt, both princes and ministers and ordinary people were buried in a rectangular tomb made of mud bricks, which the ancient Egyptians called "Mastaba". Later, a clever young man named Imhotep invented a new building method when designing a mausoleum for the Egyptian Pharaoh Zuosai. He replaced mud bricks with square stones picked from the mountains, constantly revised the design scheme of building a mausoleum, and finally built a six-level trapezoidal pyramid-this is

The prototype of the pyramid we see now.

In ancient Egypt, the pyramids were trapezoidal and layered, so they were also called hierarchical pyramids. This is a tall pyramid building with a square base and a triangle on each side, which looks like the Chinese character "gold", so we call it "pyramid". The tower mausoleum designed by Imhotep is the first stone mausoleum in Egyptian history.

After King Zuo Sai, the Egyptian Pharaoh followed his example and built a mausoleum for himself before he died. Since then, ancient Egypt has set off a wind to build pyramids. Because the pyramids originated in the ancient kingdom period, and the largest pyramids were built in this period, the ancient kingdom period of Egypt is also called the pyramid age.

Why did the pharaohs of ancient Egypt build the mausoleum into the shape of a pyramid, which is the golden shape in Chinese characters? It turns out that at the earliest time, the pharaohs in Egypt prepared to use Mastaba as their permanent residence after death. Later, during the second and third dynasties, the Egyptians came up with the idea that the king would become a god and his soul would ascend to heaven after his death. In the later discovery of the pyramid inscription, there are such words:

You should build him a ladder so that he can go up there.

The pyramid is such a ladder. At the same time, the pyramid form also expresses the worship of the sun god, because the symbol of the ancient Egyptian sun god "La" is the light of the sun. The pyramid symbolizes the sunlight penetrating the blue sky. Because, when you stand on the road to Kize and look west from the perspective of the pyramid ridge, you can see that the pyramid shines on the earth like the sun.

There is a sentence in the inscription of the pyramid: "The sky extends its own light to you, so that you can climb into the sky, just like pulling your eyes." Later, the worship of the obelisk by ancient Egyptians also had such significance, because the obelisk also represented the light of the sun.

The largest of all the pyramids in ancient Egypt is the pyramid of the fourth dynasty Pharaoh Khufu.

The original height of the Great Pyramid was 146.59 meters. After thousands of years of wind and rain, the top has been eroded by nearly 10 meter. But before the Eiffel Tower was built in Paris in 1888, it was the tallest building in the world. The bottom of this pyramid is square, each side is more than 230 meters long, and it takes almost one kilometer to walk around the pyramid.

The pyramid of Khufu is not only amazing in scale, but also famous for its superb architectural skills.

There is no cement or other adhesive between the stones of the tower, but one stone is stacked on another. Every stone has been ground down for thousands of years. It is also difficult for people to insert sharp blades into cracks in stones, so they can persist for thousands of years. This is a miracle in the history of architecture.

In addition, on the north side of the Great Pyramid, there is a triangular entrance composed of four huge stones, and the height from the ground is 13 meters. This triangle is cleverly used, because if a quadrilateral is used instead of a triangle, then the huge pressure of the pyramid with a height of 100 meters will collapse the entrance. With the triangle, the great pressure is evenly dispersed. It is really remarkable to have such an understanding and application of mechanical principles more than 4,000 years ago and to have such a structure.
