Scientists think 7 is the most special number. It is also found that in the calculation, 7 divided by 1, 2, 3, 4, 5, 6, respectively, is an infinite cycle decimal, for example:
1÷7=0. 142857……
2÷7=0.2857 14……
3÷7=0.42857 1……
4÷7=0.57 1428……
5÷7=0.7 14285……
6÷7=0.857 142……
Observing the above calculation results, I found many interesting places:
1, and the cycle node of the decimal part is in the seventh place.
2. The decimal number will not change, but the position will be exchanged.
3. The multiples of adjacent 7 are not multiples of 7 and add up to multiples of 7, for example:
1+2+3+4+5+6=2 1
36+37+38+39+40+4 1=23 1
8+9+ 10+ 1 1+ 12+ 13=63
First, there are seven-legged animals or insects in nature, but there are seven-leaf plants; However, only plants with head leaves and main leaves can have odd leaves, such as 7, 9, 1 1. Aesculus chinensis is planted in the Yellow River valley, Beijing, Jiangsu and Zhejiang, and is abundant in Guangdong, Guangxi and Guizhou. The existence of a large number of seven-leaf plants shows that although "7" is asymmetrical and irreducible in mathematics, in biology, the first leaves are centered in pairs, and the odd leaves are flourishing, just like human beings have a reasonable social structure with "first leaves and leader leaves". Second: The Big Dipper consists of seven stars. People can look up at the "shifting star" of the seven stars every night, or they can find the Polaris hanging in the north forever according to the instructions of the Big Dipper. However, people see it but don't understand it, know its image but don't understand it, and feel cordial and confused; The relationship between man and Beidou can only be the unity of known and unknown, the unity of finite and infinite, and the unity of reality and mystery. Third: the white sunlight will reflect the colors of red, orange, yellow, green, blue, blue and purple through the prism; The rainbow across the sky is also these seven colors. "7" objectively shows the beauty, wonder and mystery of nature in the rainbow, and also objectively shows God's grace and peace in the wet land and foggy air after the rain. Seven colors of sunshine, colorful; Seven-color rainbow, a wonder in the sky. Red, orange, yellow, green, blue and purple have painted countless moving pictures; Seven colors make up all the scenery of the whole world. Fourthly, mathematics is an abstraction of objective existence, and "7" is a special prime number in mathematics. Originally, "7" was just a natural number, and like 1, 2, 3, 4, 5, 6, 8, 9, it seems nothing special in counting. However, in operation, "7" is an odd, mysterious, asymmetric, irreducible and indecomposable prime number. A prime number is an integer that can be expressed as the product of itself and 1, and cannot be expressed as the product of any two other integers. In other words, a prime number is an integer that can only be divisible by 1 and itself. 1, 2, 3, 5, 7 are all prime numbers, but the reciprocal of 1 is 1, the reciprocal of 2 is 1.5, the reciprocal of 5 is 0.2, and the reciprocal of other numbers is ordinary decimal, but the reciprocal of 7 is infinite cycle decimal. Fifth, in music, "7" is the god of art in the material world. Duo, Lai, Mi, Fa, Suo and La constitute a wonderful music world. From the perspective of natural science, seven tones and eight degrees express the period of the vibration wavelength of an object; In art, 7 means natural rhyme and 7 means artistic auspiciousness. Sixth: PH value is a symbol used to measure the acid-base ratio of liquid in chemistry. When the PH value is greater than 7, the substance is alkaline, and the greater the PH value, the stronger the alkalinity; When the PH value is less than 7, the substance is acidic, and the smaller the PH value, the stronger the acidity. The substance is neutral only when the PH value is equal to 7. So 7 is the midpoint of pH value, and it is also the standard number that people pursue. With 7 as the number, the food is neither acid nor alkali, neither acid nor alkali, but sweet and sour. It can also be said that 7 expresses the moderation and appropriateness of natural things and is the golden mean of nature. Seventh: In the early 1980s, Simon began to set foot in the research of artificial intelligence, trying to make computers "think" more like people, instead of resorting to inefficient exhaustive methods to solve it. His research has made many important discoveries. However, the most important thing is that discovery gives us an answer to the mystery of "7". Simon and his colleagues found that only six or seven items of data can be kept in people's short-term memory without being forgotten by studying how people are good at dealing with a large number of new data (information flow). In other words, being able to remember seven items of data has reached our memory limit.
In psychology, "7" is a number called "incredible" by scholars. Most people's short-term memory capacity is only 7 at most. If it exceeds 7, it will be forgotten, so most people divide the memory into seven units.
Many things in life are closely related to "7". Everything related to "7" makes people feel amazing: people have "seven tricks", sunshine is composed of seven colors, seven days a week, and women's physiological period is usually seven days. The abacus has seven beads, the notation has seven notes, the PH value of water is 7 (neutral value), four lines of rhyme, the seventh day of July in ancient times, the ladybug has seven points on its back, and the Big Dipper. There are seven fairies in the myth ... if these are not magic, then we can just find a piece of paper and fold it in half. We will be surprised to find that no matter how thin the paper is, the maximum number of times any paper is folded in half is 7 times! What's even more amazing is that seven numbers composed of 1 are multiplied by themselves (111111×165438 What if the number "7" is separated? We see that1/7 = 0. 1428571428 571428 ... When we see this cyclic decimal, we are in big trouble:142857. Go on ... let's divide this 7-point by 1 and multiply it from 1 by 6. 142857* 1 = 142857
142857*2 = 2857 14
142857*3 = 42857 1
142857*4 = 57 1428
142857*5 = 7 14285
142857*6 = 857 142 The same number, but in a different position, appears repeatedly. So how much is 7 times?
We will be surprised to find that it is 999999 and
142 + 857 = 999
14+28+57 = 99 Finally, we multiply 142857 by 142857.
The answer is: 20408 122449 What are the first five plus the last six?
20408 + 122449 = 142857
This number is described on the website as follows:
142857 *1=142857 (original number)
142857*2=2857 14 (rotation)
142857*3=42857 1 (rotation)

142857*7=999999 (9 classes on holidays)
1 42857 * 8 =1142856 (7 avatars) (7 is divided into1and 6, which appear at both ends of the number respectively).
142857 * 9 =1285713 (4 avatars)
142857 *10 =1428570 (1avatar)
142857 *11=1571427 (8 avatars)

After reading it, I thought for a long time and found some secrets:
142857, 1+4+2+8+5+7=27
When you divide 7 by 142857,142857/7 = 20408.14285714285765438. ......

Seeing the magic of this number, we should think that this number is not that simple!
"7" may be a round body,142857 * 7 = 999999;
Then divide the "holy number" 1366560 by 7,

Finally, there is a model. The pattern is obvious and everyone can see it. Cotero's formula of "holy number":1366560 = (144000+7200+360+260) × 9.
1366560/36/26/4=365 (days of the earth's revolution)
1366560/36/26/16 = 91.25 (number of days in each season)
1366560/26/18/5 = 584 (Venus calendar day)
1366560/36/26/20=73 (the origin of mysterious number 73)
Venus needs 584 days to orbit the sun for many years, which is almost the same as the modern calculation of 584.92 days.
The secret is being revealed step by step! According to Genesis, God created the universe in six days and rested on the seventh day. Gen 2: 1-3: "Everything in heaven and earth was created. On the seventh day, the work created by God was finished, so he stopped all his work and rest on the seventh day. God blessed the seventh day and made it holy, because on this day, God put down all his work and rested. " Proverbs 9: 1: smart construction's house was hewn into seven pillars. In Revelation 1, the Bible says in verse 17-20: As soon as I saw it, I fell at his feet as if I were dead. He pressed me with his right hand and said, "Don't be afraid! I'm the first, I'm the last, I'm alive. I was dead, and now I am alive forever and ever, and I have the keys to death and the underworld. So, write down what you see, present and future. As for the mystery of the seven stars and the seven golden lampstands you saw in my right hand, the seven stars are the messengers of seven churches, and the seven lampstands are seven churches. " Revelation 4: 5: Lightning, sound and thunder came out of the throne. In front of the throne, there were seven burning lamps, which were the seven spirits of God. Revelation 5: 6: I saw the lamb standing among the throne, the four living creatures and the elders, as if killed, with seven horns and seven eyes, the seven spirits of God, sent to the whole world. In addition, in the Bible, Daniel also used 7 as a prophecy of many mysterious times. This shows that the number "7" is closely related to God, which is really amazing!
