It is not used in applied mathematics and is used by scientists to calculate the probability of the emergence of a new Universe from an atom
Logic trick: How old were you in 2011? To this number add the last two digits of your year of birth? It turned out to be 111, right?
Interesting facts about numbers also apply to modern technology. Thus, Google is one of the most popular search engines. It was invented by Sergey Brin and Larry Page.

Fibonacci numbers
These numbers were named after the Italian mathematician Leonardo of Pisa, known as Fibonacci, who introduced the decimal number system and Arabic numerals to Europe.
Fibonacci numbers are numbers in the following order:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, …
In this case, each next number is equal to the sum of the two previous numbers.

1. Eastern countries They are afraid of the number 4. Its pronunciation is very close to the word “death”. The Japanese, Koreans and Chinese 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 the floor is almost never recorded.
2. A small trick (elementarily explained by mathematics and logic). Take your year of birth, or rather the last 2 numbers. Do you remember how old you were in 2011? To these years add the last digits from the year of birth. Bet you got 111?
3. If you square 111 111 111, the result will be surprising! You will receive 12345678987654321. These are all numbers in order. First they increase, then they decrease.
4. Guess what happens when you add up all the numbers on a casino roulette? The number of the devil, which many are afraid of, 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 has been hit during the entire existence of the game? 3 times! Real lucky ones.
6. Everyone from school remembers the number Pi - 3.14. He even has 2 holidays. Unofficial, of course. In America it is March 14 (03.14) and July 22 (22/7). Why July, you ask? Because when you divide a number by the digit of the month, you get exactly the number Pi. It's a funny idea.
7. The largest number has 600 zeros behind the one. It has its own name. It is a centillion.
8. Interesting facts about numbers and figures also concern scientists. An American mathematics graduate student was late for class one day. Equations were written on the board. George Dantzig (that was the name of the graduate student) decided that this was a homework assignment. After tormenting himself for several days, racking his brains about how such a difficult task was given, George solved it. Imagine his surprise when he learned that this was an “unsolvable” problem in statistics. Many scientists have strained their brains 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 also with my “cockroaches” in my head 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 out of everyone? And the composer Schoenberg Arnold was afraid of the devil's dozen. And he died on Friday the 13th at the age of 76 (you know how much 7+6 is?). This is the magic of numbers. And he only says that thoughts are material. And you don’t need to create fears for yourself so that they don’t “finish” you off.
11. Another interesting fact about the devil's number. Imagine that in the USSR, architects wanted to create a microdistrict by building houses in it in such a way that the name of a great power could be read from space. However, I somehow didn’t like the idea or finances didn’t allow it. But as a result, in Kharkov there is the 522nd microdistrict, 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. The amazing thing is 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. The centipede actually has far from 40 legs. People often call this a spider with long, thin “legs.” She moves so fast that she seems to have 40 legs. However, some people call centipedes centipedes, which in fact have up to 400 legs, and sometimes even more. 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 that year that Stalin celebrated his anniversary - his seventh decade. And so the very first trolleybus was assigned No. 70 (although now such a route no longer exists). Since then, route numbers have been given after 70. There is no first, no twentieth, no fifty-third.
15. Is it possible to live a million days? Interesting. But if you count, it’s 27 centuries. Not many days have passed since the beginning of our era. So the answer is clear - no, one person cannot live that many days.

In the Mathematical Kingdom there lived the number Three. And she liked everything. But then one day she decided that she was tired of living in the Mathematical Kingdom, and she decided to move to the Poetic Kingdom. “I’ll try to compose poems in which my name will sound,” she decided. First of all, number 3 decided to look for a rhyme with the word “three”. And this is what she came up with: “Wipe, erase, look, sharpen up.” “Yes,” thought Number Three, “no good poem, no worthwhile poetic work will come from these words.” Number Three thought and thought and decided: “Since I was born a number, I will remain a number. I won't be a poet. Where they count, I feel confident and comfortable. And in the Poetic Kingdom let letters rule.”
Who is number 3 friends with?
Once upon a time there was a cheerful traffic light. He stood at the intersection and flashed three lights: green, yellow and red. But one day all three lights went out.
What started here! The cars couldn't get through because they were all driving at once. Pedestrians could not cross the street because they were afraid of getting hit by cars. Luckily, there was a little girl in the crowd of pedestrians. She knew that the traffic light was friendly with the number 3, and rather called her:
– Hello, your friend the traffic light is sick and he urgently needs help!
Number 3 immediately came running and brought him three delicious triangular cookies. She treated
a traffic light with cookies, and it immediately lit up.
It turns out that the traffic light was very hungry, and therefore could not work anymore.
Since then, the number 3 comes to visit the traffic light every day. When the traffic light shows cars with its red eye and traffic stops, the number 3 feeds it three triangular...
Fairytale meaning numbers 3.
Number 3- you must have noticed how often it is mentioned in fairy tales? “The father had three sons,” “he rode for three days and three nights,” “it’s a piece of cake.” “Clap your hands three times,” “turn around your axis three times,” “say something three times.”
Digit 3 in Russian folk tales is simply decisive. I don’t know where the common people gained so much wisdom... But from an esoteric point of view and from the position of spiritual numerology number 3 used in Russian fairy tales incredibly accurately and appropriately.
In folklorenumber 3 very often reflects precisely the turning points in a person’s life. This is especially visible in the “three roads”, which are usually laid out in front of the main characters at the moment of the inevitable choice . And not just “inevitable”, but a fateful choice, which is actually a matter of life and death.
It’s enough for the main character to fail to guess the right direction - and that’s it, “goodbye, dear.” Choke on Baba Yaga's bones! The curtain falls. Frustrated spectators dejectedly trudge towards the exit, barely discerning the road in the fog of uninvited tears.
