The string of numbers "142857" was discovered by experts during archaeological work in the pyramids of Egypt, and is called "Liushui". It is called "the most magical number in the world" because it is a circular cross section on the decimal place of the quotient of a number that is not divisible by 7. Some people even associate it with the cosmic code and the Wenchuan earthquake that occurred in 2008 14: 28: 57.
In fact, the number 142857 is amazing, but it is not as fantastic as people advertised. After all, Arabic numerals are just counting symbols invented by human beings. It originated 500 years ago, was invented by ancient Indians, then spread to Europe by Arabs, and finally modernized by Europeans. Therefore, in the long run, this counting symbol originally invented by ancient Indians has been handed down as "Arabic numerals".

Generally speaking, when people explore the mysteries of some numbers, they will always think of some natural phenomena, which will actually affect our correct understanding of the laws of nature.

However, the "weekly system" was established by Babylonians in Cuba. It was founded by observing the changing law of the moon round by round, and then the lunar calendar was calculated, without such complicated operations of addition, subtraction, multiplication and division.
