Mathematicians are naturally more authoritative about numbers. Mathematicians think that the results of multiplying 142857 by 1 ~ 6 are 142857, 2857 14, 42857 1 57 1428, 7/kloc, respectively. A wise man can understand the result at a glance. The same six numbers have not changed, but their positions have changed. 142857 times 7 to get 99999. Continue down, and when you reach 14, the result is 199998. The result obtained by adding the first number 1 and the following numbers is the same as that obtained by multiplying 142857 by 7.
In this way, if we continue to multiply, we can get a rule: when 142857 is multiplied by a number other than a multiple of 7, the result is the combination of the first few digits and the last six digits of 1/4/2/8/5/7, and it is a regular cycle, and the result after multiplying by a multiple of 7 must be 9999.
In addition, if 142857 is divided by addition,142+857 = 999; 14 + 28 + 57 = 99。 142857 ? =20408 122449, divide by 20408+122449 =142857, and you will return to the original number. What's even more amazing is that not only multiplication and addition have rules to follow, but even division has rules to follow! 142857 is multiplied by 1 to 6 and then divided by 7 to get the decimal cycle of 142857. I really should say: Heaven is reincarnation, 99 is one? .
Even if mathematicians like the above repeatedly study the demonstration algorithm, they have not solved the cleverness of this series of numbers. So who left such a magical number coincidence in which era? What is the real mystery? The answer is unknown. However, the number mystery of the Egyptian pyramids goes far beyond this set of numbers.
For example, in the largest pyramid of khufu, the error rate of four sides is less than 1% on the base with a side length of 9063 inches, and the error of artificial construction is amazing. Its corner structure is also suitable for modern architectural problems? Right angle technology? , reaching an error of 2 seconds.
Besides, many people want to know why the pyramids have stood for more than four thousand years.
In fact, it is because the clever ancient Egyptians deliberately set the pyramid position on the earth, which is 30 north latitude? Only a slight error of 29 degrees 58 minutes 5 1 second north latitude can make the pyramid bear its tiny amplitude when the earth rotates.
It is because of the mystery of these pyramids that some people think that aliens helped the ancient Egyptians. But in fact, these real things were created by human beings, the great ancient Egyptians. And we believe that with the development of science and technology, the mystery about the pyramids will be solved one by one.
