The mysterious number PI is a mathematical constant that is the ratio of the circumference of a circle to its diameter. For many centuries, it has occupied the minds of mathematicians around the world. He is considered even mystical, not amenable to rational explanation. This is especially surprising because mathematics is the most exact of all sciences. But she only has assumptions about patterns in the chaotic sequence of the mathematical constant PI.
In 1794, scientists proved that PI is an infinite irrational number. Its generally accepted designation is the Greek letter "π". The mystery of PI goes far beyond pure mathematics, this number can be found in formulas and phenomena inherent in other sciences - astronomy, physics, relativity theory, genetics, statistics. The ubiquitous number PI, with its bewitching sequence of numbers going to infinity, is something of a work of art for people who are not indifferent to mathematics.
Fans of the exact sciences in many countries of the world even celebrate PI Day. Of course, this holiday is not official. It was invented in 1987 by the American physicist Larry Shaw. The date chosen for the celebration is not accidental, it is, as it were,encoded in the constant itself. Knowing what the number PI is equal to, you can guess the date of the holiday in his honor.
From the school curriculum, we know at least 7 decimal places that were memorized as a rhyme - "3-14-15-92 and 6". The third month, the 14th … So it turns out that on March 14, exactly at 1.59.26, the number of PI comes into play. Celebrating mathematicians give speeches in honor of the constant, eat a cake with the Greek letter "π" or the first digits of this number depicted on it, play various games, solve puzzles - in a word, have fun in the manner appropriate for mathematicians. A funny coincidence - on March 14, the great Albert Einstein, the creator of the theory of relativity, was born.
PI fans compete to learn as many digits of the constant as possible. The record so far belongs to Colombian resident Jaime Garcia. It took the Colombian three days to voice 150,000 characters. The human-computer record was confirmed by professors of mathematics and listed in the Guinness book.
The number of PI cannot be completely reproduced, it is infinite. There is not a single cyclic sequence in it, and, according to mathematicians, one will never be found, no matter how many more signs are calculated.
American mathematician David Bailey and his Canadian colleagues created a special computer program, calculations on which showed that the sequence of digits of the number PI is really random, as if illustrating chaos theory.
Throughout the centuries-old history of the number PIthere is a kind of pursuit for the number of its digits. The latest data was deduced by Japanese scientists from the University of Tsukuba - the accuracy of their calculations is more than 2.5 trillion decimal places. The calculations were made on a supercomputer equipped with 640 quad-core processors and took 73 and a half hours.
In conclusion, I would like to quote an excerpt from a children's poem by Sergei Bobrov. What do you think is encrypted here?
22 owls missed big dry bitches.
22 owls dreamed
about seven big mice"
(When you divide 22 by 7, you get…pi number).
