1. Eastern countries they are afraid of the number 4. Its pronunciation is very close to the word "death". The Japanese, Koreans, and Chinese have equated it with an "unlucky" number. If you pay attention to the number of floors in buildings, you will notice that the number "4" at the end of a floor is almost never recorded.

2. Small trick (elementary explained by mathematics and logic). Take your year of birth, or rather the last 2 digits. Remember how old you were in 2011? Add the last digits from the year of birth to these years. We bet you got 111?

3. If you square 111 111 111, the result is surprising! You will get 12345678987654321. These are all the numbers in order. First they increase, then they go down.

4. Guess what happens when you add up all the numbers on the casino roulette? The number of the devil, of whom many are afraid, is 666.

5. Many people know about various lotteries "6 out of 49" (as it used to be in Sportloto). Do you know how many times the jackpot was hit during the entire existence of the game? 3 times! The real lucky ones.

6. Everyone from school remembers about the number Pi - 3.14. He even has 2 holidays. Informal, of course. In America it is March 14 (03.14) and July 22 (22/7). Ask why July? Because when you divide the number by the number of the month, you get just the number Pi. Funny idea.

7. Most big number has 600 zeros per one. It has its own name. It is a centillion.

8. Interesting Facts about numbers and figures also concern scientists. An American graduate student-mathematician once was late for class. Equations were written on the blackboard. George Danzig (that was the name of the graduate student) decided that it was asked at home. After suffering for several days, puzzling over how such a difficult task was given, George solved it. What was his surprise when he learned that this is an "unsolvable" problem in statistics. Many scientists have strained their convolutions for many years to unravel the mystery of these problems.

9. Guess which is the most common female name? Anna. 100 million women are named by him.

10. Famous people, too, with their "cockroaches" in their heads and fears. For example, Sigmund Freud was terrified of the number 62. This went so far that Freud did not stay in hotels with more than 61 rooms. What if he, the lucky one, gets 62 of them all? And the composer Arnold Schoenberg was afraid of a damn dozen. And he died on Friday the 13th at the age of 76 (do you know how much 7 + 6 is?). here it is - the magic of numbers. And he only says that thoughts are material. And you do not need to create fears for yourself so that they do not "finish off" you.

11. Another interesting fact about the devilish number. Imagine that in the USSR, architects wanted to create a microdistrict, building houses in it in such a way that the name of a great power could be read from space. However, the idea somehow fell out of favor or the finances did not allow it. But as a result, there is a 522th microdistrict in Kharkiv, where there are only 3 houses. And the satellite shows them on the map as "666".

12. In the Himalayas there is a sacred mountain with a height of 6666 m. Its name is Kailash. It is striking that its height is the distance to the center of the North Pole and at the same time to Stonehenge. Some kind of mysticism. But the mountain is actually very beautiful.

13. A centipede actually has more than 40 legs. People often call this a spider with long and thin "legs". She moves so fast that it seems 40 legs. However, some people call centipedes centipedes, in which, in fact, the number of legs reaches 400, and sometimes even higher. Those who count 100 legs should be wary of this insect. It bites painfully. But the so-called millipedes are generally harmless and harmless. Biology is an interesting science.

14. In Budapest, trolleybuses received numbers in 1949. It was in that year that Stalin celebrated his anniversary - his seventh decade. And so the very first trolleybus was assigned number 70 (although now there is no such route anymore). Since then, route numbers have been given after 70. There is neither the first nor the twentieth, nor the fifty-third.

15. Is it realistic to live a million days? Interesting. But if you count, then this is 27 centuries. Not many days have passed since the beginning of our era. So the answer is unequivocal - no, one person cannot live so many days.

Getting acquainted with the number 0, hardly anyone imagined that this is one of greatest discoveries! Have different methods There was a flaw in the designation of numbers invented by the Egyptians, Greeks and Romans: as the numbers increased, new signs were needed. The great Archimedes learned to name huge numbers, but he did not know how to designate them. The smallest thing was missing - zero! For the first time 0 was invented by the Babylonians (two thousand years ago). But they used it only to indicate the missing digits in the middle of the number. They did not guess to write zeros at the end of the number. In India, around the 19th century, zero was attached to nine digits and it became possible to designate any number with these ten digits, no matter how large it was. And most importantly, the entry became short. After this discovery, people received a powerful instrument for learning about nature. Indeed, without zero, many scientific achievements would not be possible, for example, space flights and the invention of computers. - We are from 90. ID 048 18:53, 24 October 2012 (MSD)))

• Number 42... There are not so many mystical numbers in the history of mankind. But very few people know about the number 42. And it is very mystical and unusual!

In the Egyptian Book of the Dead it comes that at the death judgment people will need to bear responsibility for their 42 mortal sins before 42 gods. Before leaving his body and staying in the astral plane forever, Buddha answered questions for forty-two years. Even our beloved Gogol, who was very fond of mysticism, did not ignore this number. In his story "The Nose", the main character had to reach the age of 42 - this is how he justified his ardent unwillingness to tie the knot. The prayer "Ana be koakh", which the worshipers of Kabbalah know, consists of seven lines, and each line contains six words (7x6 = 42). And if you add up the first letters of all these words, you get the name of God. And what is interesting is that they begin to study Kabbalah only when they are 42 years old. 42 looks like a symbol of the life and creative destiny of the poet A. Balmont, he was born 42 years after the uprising of the Decembrists, collaborating in the anti-government magazine Red Banner, published in Paris, he published 42 poems there. Balmont died in 1942.

• Why 360 degrees in a circle

The history of the development of mankind knew different systems reckoning. In Ancient Babylon, the sixagesimal number system was invented. The Babylonians counted in threes, according to the number of joints on each finger of the left hand, that is, up to 12. Then each finger right hand meant 12. Thanks to this, the counting continued until 60. The number 60 became ritual in Ancient Babylon: there were so many gods, and each of them had its own numerical designation from 1 to 60. For example, the creator of the universe was designated by the number 20; the god of the planet Jupiter - 11; the god of the moon - 30. The height of the golden idol installed in the temple of Nebuchadnezzar was 60 cubits. It is not surprising that the number 60 formed the basis of the ancient Babylonian calendar. Observing the features of the circular motion of the Moon and the Sun, the Babylonians came to the conclusion that the year consists of 360 days. Therefore, they divided the circle into 360 degrees, one degree for each day. The year was divided into 12 months, because the Sun lingers in each constellation of the Zodiac for about a month, and the Moon moves across the sky in a month - 30 days. In one of the Babylonian temples, there was a statue of a god surrounded by 360 jugs, each of which symbolized one of the days of the year. CHILDREN X IDm2012 062 22:01, 7 November 2012 (MSK)

• From the history of zero.

The word "zero" comes from the Latin word "Nulla" meaning "none" (significant digit). The Greek astronomers, who used hexadecimal fractions, introduced a special sign for the division of the digits, shaped like the letter O (omicron, the first letter in the Greek word "onden", meaning "nothing"). In the VII century. v Ancient India the decimal positional number system was already used, and together with it, zero was systematically used, which was denoted by a dot, as well as a circle. Some scholars believe that the circle for zero was introduced by the Greeks. The Indians called zero "sunya", which meant "empty", in the sense that there was no place in the number. Arabs from whom the Europeans took over decimal system reckoning, translated the Indian "sunya" into the Arabic word "as-sifr". That is why until the 17th century. zero was called a "digit". For Europeans, Indian arithmetic and, in particular, zero were initially considered some kind of secret. Therefore, they began to give the name "numbers" or "cipher" of any cryptography. Currently, zero is not just a sign for separating the digits, but a number that can be added. subtract, multiply and divide like other numbers. The only restriction is that you cannot divide by zero.

• About pi

It is known that the ratio of the circumference of a circle to the diameter cannot be accurately expressed by either an integer or common fraction, nor a finite fraction. Archimedes obtained approximate values ​​for pi with a deficiency and an excess by considering the polygons inscribed in a circle and described around it with sufficiently a large number parties. In some Asian countries, the value pi = root (10) is found, i.e. 3.162 .... Astronomer Wang Fan (229-267) argued that pi = 142/45, i.e. 3.155 ..., and Tzu Chun-chih (428-499) spoke about the "inexact" value of 22/7 and the "exact" 355/113, showing that pi is between 3.1415926 and 3.1415927. The last value was recorded in the 7th century. in the form of a named number: 3 zhang 1 chi 4 cunya 1 fen 5 li 9 hao 2 miao 7 ho.

Facts about numbers. These are prime numbers and many others. Some numbers, such as Pi and a number of others, we brought out in separate materials. So we advise you to read them too. Here are a few fun facts about numbers, which, for sure, will be of interest to you.

Facts about negative numbers

Nowadays negative numbers known to many, but this was not always the case. For the first time, negative numbers began to be used in China in the 3rd century, but they were allowed to be used only in exceptional cases, since they were considered nonsense. Somewhat later, negative numbers began to be used in India to denote debts.

So, in the work "Mathematics" in nine books, published in 179 AD. BC, during the Han dynasty and commented in 263 by Liu Hui, in the Chinese system of counting sticks, black sticks were used for negative numbers, and red ones for positive ones. Also, to indicate negative numbers, Liu Hui used oblique counting sticks.

The "-" sign, which is now used to denote negative numbers, was first seen in the ancient Bakhshali manuscript in India, but there is no consensus among scholars as to when it was compiled, the range of disagreement is from 200 to 600 AD. NS.

Negative numbers were already known in India in 630 AD. BC. They were used by the mathematician Brahmagupta (598-668).

For the first time in Europe, negative numbers began to be used around 275 AD. They were introduced into use by the Greek mathematician Diophantus of Alexandria, but in the West they were considered absurd until the appearance of the book Ars Magna (Great Art), written in 1545 by the Italian mathematician Girolamo Cardano (1501-1576).

Prime facts

The numbers 2 and 5 are the only ones in a series of primes that end in 2 and 5.

Other facts about numbers

The number 18 is the only number (except 0), the sum of the digits of which is 2 times less than itself.

2520 is the smallest number that can be evenly divided by all numbers from 1 to 10.

The number "five" in Thai is pronounced "ha". Therefore, the number made up of three fives - 555, will be pronounced like a slang phrase denoting human laughter - "Ha, ha, ha."

We all know that there are palindrome words. That is, those that can be read from left to right and from right to left and their meaning does not change. However, there are also numbers-palindromes (palindromones). They are mirrored numbers that will be read and have the same value in both directions, for example 1234321.

The word Googol (the origin of the Google brand) stands for the number 1 followed by 100 zeros.

The only number that cannot be written in Roman numerals is "Zero". Also, in modern mathematics, zero has some peculiarities of its interpretation. So, in Russian mathematics, he is not ranked among the series natural numbers, and foreign science relates.

We all know the numbers from 0 to 9. And how did they come about? Where did these familiar 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 come from, which we constantly use in Everyday life? What are they called and why do they have such a name? Let's plunge into history and find out the answers to these and many other questions.

The history of numbers

Even in ancient times, a person needed an account. Even when there were no letters and numbers yet, when ancient man did not know what two or five was, he had to perform simple actions to divide the prey, determine the number of people for hunting, and many others.

Initially, he used his hands, and sometimes even his feet, showed on his fingers. Remember the saying "I know my 5 fingers"? It is possible that it was invented in those distant times. It was the fingers that were the first instruments for counting.

Life went on as usual, everything changed, people needed some other signs besides fingers. The numbers became more and more, it was difficult to keep them in the head, it was necessary to somehow denote and write them down. This is how the numbers appeared. And different countries came up with their own. The first were the Egyptians, then the Greeks and Romans. Now we sometimes use Roman numerals. However, the most popular and used by us to this day are the numbers invented in India before the beginning of the 5th century.

Why are they called that?

Why are the usual numbers called Arabic, because they were invented in India? And all because they got widespread thanks to the Arab countries, which began to actively use them. The Arabs took Indian numbers, changed them a little and began to actively use them. Among those who helped the world to discover the well-known Arabic numerals were the Frenchman Alexander de Villiers, the British teacher John Halifax and the famous mathematician Fibonacci, who often traveled to the East and studied the works of Arab scientists.

The word "digit" itself is of Arabic origin. The consonant Arabic word "sifr" denotes the icons that we are used to using 0,1, 2 ... 9.

Let's take a closer look at the numbers

Number 1

Guess the riddle:

Sister with a sly nose
The account will be opened ... ( unit)

That's right, this is number 1. The very first number. It's easy to write. It is with her that acquaintance with numbers always begins. Any number can be made from units, for example 1 + 1 = 2, etc. In China, one is the beginning of everything. However, we also have. The beginning of the school year is September 1, and New Year- January 1st.

Number 1 symbolizes the beginning, unity, integrity, like God, sun, universe, space. It is an indivisible and unique number.

Millions of creation without a pair are not whole ... For example, two wings, two eyes, two ears and other parts of the body. Any family starts with two ...

The number two is often found in the literature. Remember Krylov's fables "Two Doves", "Two Dogs" or the tale of the Brothers Grimm "Two Brothers", Nosov's tale "Two Frosts". Two is the smallest prime number. And also the worst grade in school. In order not to get deuces, you need to study well.

Number 3

What a miracle
What a figure!
Every tomboy knows.
Even in our alphabet
She has a twin sister ... ( three)

Number 3.

The number really looks like the letters of the Russian alphabet "Z".

Number 4

I am after the number 3,
And the number five is slightly inferior.
What kind of figure am I?

Number 4. It is said that the four is the most magical of the numbers. In most states, it is a symbol of integrity. But in Asian countries they treat it with apprehension. In life we ​​meet the number 4 very often: 4 seasons, 4 cardinal points, 4 natural elements, 4 times of day, etc.

Number 5

How many fingers on the hand
And a penny in a patch,
The rays of the starfish
Five rooks have beaks,
Maple leaves
And the corners of the bastion
Tell about all this
The figure will help us ... (five)

Number 5. In most schools, this is the best grade! Although, for example, in Germany, the top five is given on the contrary to those who try badly. Where can we meet the top five? For example, there are 5 continents on Earth, and the symbol of the Olympic Games has 5 rings, and there are 5 fingers on the hands and feet.

Number 6

How many letters does the dragon have
And a million zeros
Different chess pieces
The wings of three white chickens,
Beetle legs
And the sides by the chest.
If we cannot count ourselves,
Will tell us digit ... (six)

Number 6. The most tricky number. If it stands on your head, the number 6 will become a nine. The cube has 6 faces, all insects have 6 legs, many musical instruments have 6 holes each - these are examples of where the number 6 occurs in life.

Number 7

How many colors are there in a bright rainbow?
How many wonders of the world are there?

Well this is necessary! We carry the number
On the bow, take a look, please.
This figure plus hooks -
Points are obtained ...

Number 8. Number 8 - inverted infinity sign. For many peoples, this figure is special. For example, in China, it means prosperity and wealth. The famous mathematician Pythagoras also believed that the number 8 is harmony, balance and prosperity. Do you remember what holiday we celebrate on March 8th? How many hooves do two cows have? How many legs does a spider have?

Number 9
