This is because among the seven wonders of the world, the pyramid is the only one that has not been deciphered by time. It was built more than 2000 years earlier than other miracles. After thousands of years of weathering, it is still intact and has become a symbol of standing.
The pyramid is a pyramid-shaped building with a square base. When we look from the side, we see a triangle on each side, which is very similar to the triangle in our Chinese characters? Kim. Word, so we call it the pyramid. The pyramid was built in the shape of a pyramid because the Egyptians thought that Pharaoh would become a god and his soul would go to heaven after his death, so the pyramid was a ladder for Pharaoh's soul to go to heaven.
This view is confirmed in the inscription on the pyramid, which reads? Build a ladder to heaven for Pharaoh so that he can go to heaven from there? .
The highest pyramid in the world is the pyramid of khufu, which consists of more than 2 million boulders, which were mined from the east bank of the Nile. Each boulder weighs more than 2,000 kilograms, and the largest stone weighs more than 50 tons.
Because there were no explosives at that time, the Egyptians used bronze chisels to drill holes in stones, and then inserted wood to water them. When wood foams, stones diffuse through the expansion force of wood, thus forming stones. It seems nothing now, but it was a great technology at that time. But the mined stone is so heavy, how can it be transported from Hedong to its destination?
French scientist Davis speculated that it was probably the Egyptians who carried the mixed concrete to the pyramids in baskets and then poured it into the stones. This layer-by-layer production is theoretically possible. Later, Davis also found human hair in stones, which further illustrated the feasibility of this conjecture.
Clever ancient Egyptians not only built such a huge pyramid with clever buildings, but also made it stand for more than 4000 years. How did this happen?
It turned out that the ancient Egyptians built the pyramids on the line of 30 degrees 29 degrees 58 minutes 5 1 second north latitude, so that the pyramids could bear the slight amplitude of rotation with the earth, which is why the pyramids can stand still.
With the development of modern science and technology and the continuous research of scientists, the mystery of the pyramid has been gradually solved, but a series of numbers 142857 found in the pyramid have not been reasonably explained so far.
So what's the magic of 142857?
Let's take a look. First, multiply the serial number of 142857 from 1 by 7, and the results obtained by multiplying 1 by 6 are all composed of 1, 4, 2, 8, 5 and 7, but the order of numbers has changed, and multiplying 7 is 9999.
Let's move on. When we multiply it by 14, the result will be the same as that of multiplying it by 1 to 7. ?
If this goes on, we get a rule that when 142857 is multiplied by a number other than 7, the last six digits and the first digits of the result must be the combination of the numbers 1/4/2/8/5/7, and it is a regular cycle, and the result after multiplying by 7 must be 9999.
After calculation, the magic is not only multiplication and addition, we multiply 142857 by 1 to 6 and then divide it by 7, and we get the decimal cycle of 142857.
Many mathematicians are puzzled by this question, so 142857 has become a magic number.
In the pyramids, there are still many mysteries that cannot be explained so far, such as 142857. After the continuous excavation of archaeologists and the progress of human science and technology, a reasonable explanation will eventually be given. The ancient Egyptians had such high mathematical wisdom 5000 years ago, which really deserves our applause.
