# The Most unusual holiday of the year

An outstanding day for lovers of mathematics and one of the most unusual holidays of the year is March 14. After this day that part of mankind who is not indifferent to mathematics, celebrates the international day of “PI”.

The most remarkable thing in this festival what it is celebrated at certain times, namely on March 14 at 1:59 of the day, i.e. at 13:59, if you stick to the 24-hour time system. Although some fans of this holiday you prefer to celebrate it at night. “Why at this time?” you ask. It’s very simple, because Π = 3,14159, which is March 14 – it 14.03 or 3/14, as this date is indicated in different countries and 1:59 – this time on 12-hour system of time measurement.

Universal number

In the mathematical world, the number of “PI” is a constant that expresses the ratio of the perimeter of a circle to its diameter. The most interesting thing in this number what the numbers are after the decimal point, did not Express any cyclical or logical sequence – 3,141592653589793238462643… and to infinity. The uniqueness of the number “PI” is that in decimal decomposition can be written in any sequence. Thus, “PI” you can encode any information until all written and unwritten books. In addition using the number “PI” you can define any constant, which is why Π can be considered a universal number that can be used both in geometry and in the theory of relativity, nuclear physics and quantum mechanics. But recent DNA research has shocked scientists new discovery. It turns out that the number of “PI” is responsible for the structure of DNA! In addition some scientists have long been whispering that Π – this is a reasonable number that controls all the processes of the universe, while remaining unchanged.

History of the number of “PI”

The number of “PI” people have become interested in ancient times. To be more precise, it is worth noting that our ancestors became interested by the ratio of a circle’s circumference and its diameter, but they took too imprecise pattern by which it was believed that the number of “PI” is set to 3 (three). In the era of the development of the exact Sciences, our ancestors realized how deeply wrong they were. At this time the value of the number “PI” was the ratio of 22 to 7, which brought Archimedes. Moreover, he became the author of the well-known Π, which we know today as 3,1415926. As many scientists say, for home use it is enough that value. But anyone interested in domestic use number “PI”, when it comes to precise calculations, for example, the orbit of the satellite. In this case, the more decimal places we have, the more accurate will be our computations. Therefore, many scientists still “improve” Π, trying to look into that infinity is striving for that number. To date, the world record for calculating the number of “PI” is owned by a Japanese math Professor at the University of Tokyo Yasumasa Canada, who was able to calculate it 12411-trillion mark! Agree, for the average man is a surreal number, and if we take into account the fact that the computation of the number of “PI” is not a trivial division on the calculator, and use of a variety of formulas and calculations.

Proceeding from the fact that among the “PI” no sequences or repetitions, scientists came to the conclusion that it is subject to chaos Theory or is a numeric value of the chaos. And most importantly, that this chaos can be represented graphically in the image, the number of “PI” could do an American mathematician Stanislaw M. Ulam, who at a conference began drawing on a piece of graph paper figures that are among the “PI”. As a result, he received an image that was very similar to something reasonable. Thus giving your drawing some colour to the algorithm, and Ulam received a colorful picture, which resembles the human brain or a stellar nebula.

Thus, in 1965, the year the first time scientists were able to face one of the most reasonable numbers in the universe.

Interesting facts about the number “PI”

It is interesting that true fans of mathematics and in particular in the number of “PI” is celebrated on the 14th of March the international day for the number of “PI”, and on 22 July, Day of the approximate number of “PI”. This tradition is primarily associated with the initial ratio, which is expressed in the number of “PI” as the ratio of twenty-two to seven.

Today, fans Π club organized a number of “PI” and organize different events like: “The best verse on the number of “PI” or “the Best greetings on the Day the number “PI” and so on. While ardent fans of the Π defend each digit of its value as an important link. However, not all share a similar point of view. For example, in 1897, the year in Indiana was an attempt to round the value “PI” from 3,14 to 3.2, however, this law has not been approved only thanks to the efforts of Professor of mathematics at Purdue University.

Of course, there are people who are very sensitive to the number of “PI”, and many more of the inhabitants are indifferent to his fate, but every year brilliant minds of mathematicians, sitting in a cafe, chanting poems and toasts devoted to this unique number, which is only slightly opened to us their secrets. But let’s hope that our descendants will reveal all points above the “PI”!
