Mysterious number pi - the mathematical constant that is the ratio of the circumference and its diameter.For centuries, it has occupied the minds of mathematicians all over the world.He is considered, even mystical, defy rational explanation.This is particularly surprising because the math - the most accurate of all the sciences.But she has only assumptions about patterns in chaotic sequence of the mathematical constant pi.

In 1794 scientists proved that PI - infinite irrational number.Universally recognized symbol of it is the Greek letter "π".Mystery PI goes well beyond pure mathematics, this number can be found in the formulas and phenomena inherent in other sciences - astronomy, physics, relativity, genetics, statistics.Omnipresent number PI with its fascinating sequence of numbers, going to infinity, for people who are not indifferent to mathematics, is something of a work of art.

Fans of the exact sciences in many countries even celebrate Pi Day.Of course, this is not an official holiday.It c

from the curriculum, we know at least 7 decimal places, which have been memorized as a poem - "3-14-15-92 and 6".The third month, 14 day ... So it turns out that on March 14 at exactly 1.59.26 enters into the rights of pi.Celebrating lovers of mathematics speeches in honor of constant eating cake with a picture on it by the Greek letter "π" or the first digits of the number, play various games, solve puzzles - in a word, fun way for mathematicians properly.Funny coincidence - 14 March was born the great Albert Einstein, creator of the theory of relativity.

Fans of Pi compete in trying to learn as much as possible the number of digits of constants.Record is owned by Colombian citizen Jaime Garcia.It took three days to Colombian scoring 150 thousand characters.The record of human-computer confirmed by professors of mathematics and is listed in the Guinness Book.

Pi completely impossible to reproduce, it is infinite.There is not a single cyclic sequence, and, according to mathematicians such never show up, no matter how much more calculated signs.

American mathematician David Bailey with their Canadian colleagues created a special computer program, on which the calculation showed that the sequence of digits of pi truly random, as if illustrating the theory of chaos.

Throughout the long history of being a kind of PI pursuit of the number of its digits.Recent data managed to bring Japanese scientists from the University of Tsukuba - the accuracy of the calculation is more than 2.5 trillion decimal places.The calculations were performed on a supercomputer equipped with 640 quad-core processors, and took 73 and a half hours.

In conclusion I would like to quote from a children's poem by Sergei Bobrov.Do you think that there is encrypted?

«22 owl missed out on the big dry bitches.

22 owls dreamed

seven large mice »

(When you divide 22 by 7 turns ... Pi).
