The number Pi, as you know, is the ratio of the circumference of a circle to its diameter. Pi is an irrational number, that is, as a simple fraction it can not be represented. Pi expressed as infinite, non-repeating decimal (3.14159 …) fractions, or in the form of such a fraction: 22/7.
Here are some interesting facts about this irrational number.
Pi number opening
Ancient Babylonians knew about the existence of Pi for more than 4000 years back. The Babylonians got the value of Pi as 3.125. A little bit later (in 1650 BC), based on data from ancient Egyptian mathematicians, the Pi number is being specified and has its value – 3.1605. Greek mathematician Archimedes (287-212 BC) for the first time based on a constant Pi deduced the dependence of the circumference and geometric polygon parameters (perimeter, bisector, median and etc.).
The “language” of Pi
Literary scholars invented a dialect known as Pilish, in which the number of letters in consecutive words corresponds to a number Pi numbers. For example, Mike Kate wrote his book “Not Wake” in its entirety. in the language of this unique number.
How to remember the number Pi
In order to remember this complex number, many people use mnemonic techniques known as piphilology. For example, to remember the meaning of Pi, they use poems, written in the Pilish dialect (in each word the number of letters corresponds to Pi). Guinness World Record Memorized by the digits of the number Pi, belongs to the Chinese Chao Lu. Chao memorized about 7,000 thousand consecutive digits of this numbers.
Giza Pyramid
Writer John Taylor first suggested that the Great project the pyramids of Egypt in Giza, built in 2589 – 2566 BC era, was developed based on the Pi number. Taylor found that the division of the perimeter of the base of the pyramid by its height is approximately equal a number close to 2 * Pi. Other specialists also often see the mathematical relationship between Pi and the Great Pyramid of Egypt.
Calculations using Pi
Today, mathematicians with the help of the Pi number can easily calculate circle measurements, the distance along the edge of a round or curved object, diameter of circles, etc. Today with computer technology has made it possible to produce even more accurate calculations, since according to the data for December 2013 it is known about 12 trillion. digits after the decimal point in the number Pi.
