# International day number "PI"

On March 14, have a celebration of one of the most amazing celebrations – the International day for the number "PI". On this day known to all people concerned about the mathematics. It is generally accepted that the idea of this holiday belongs to physics Larr Show that noticed that in American writing, this date will appear as the number of "PI" – 3.14.

This is highly unusual, we found already in the early grades, ranging study circle. "PI" has infinite mathematical expectancy. At the present time, this mathematical constant numbers after the decimal point 12411 trillion digits. And repetitions of the sequence is not found. According to the authoritative opinion of some eminent mathematicians and physicists not find anyone. Scientists see this as a hidden mystic, believing that "PI" hidden infinite primordial chaos that after reborn in harmony, and maybe some other, no less mysterious information.

In everyday calculations, it is customary to use simplified this number (3,14).

According to the experts, "PI" was opened by the Babylonian Magi. During the construction of the tower of Babel was used this mathematical constant. But, the error in the account led to the collapse of the project. The symbol "PI" was first used in 1706 by William Jones, but the true popularity he received after use in the works of the mathematician Leonhard Euler.

Mnemonist love to remember the number of "PI". They actively compete in the number of digits that they can remember. Champions can be found in the book of records. Hideaki Tomoyori from Japan can tell the number of "PI" to 40 000 characters. To remember is the number of digits he spent 10 years. The Chelyabinsk Alexander Belyaev able to reproduce 2500 characters. Ukrainian neurosurgeon, Professor Andriy Slyusarchuk in 2009 set a record with thirty million marks "PI" occupied 20 volumes of text.

This number is everywhere. In a glass, plate, any star, in all that round. The funny thing is that in certain combinations of character "PI", you can find any digital sequence. Congratulations to you, the fans mathematics!
