Fact 1: In the Greek alphabet, ‘œpi’ was introduced by an English Mathematician in the year 1706. In the year 1737, the symbol pi was used by Euler to represent the value of it. Â Pi was taken from the Greek word called ‘œpiwas.’ Pi is the 16th Â letter in the Greek alphabet.

Fact 2: The value determined for pi Â is described as the number of times a diameter of the circle fits into the circumference.

Fact 3: The value of pi is written as 22/7 and is also represented as 3.14.

Fact 4: The pi value does not have a zero after the decimal point.

Fact 5: The value of pi is used in several geometrical calculations and scientific calculations involved in many the subjects including: genetic engineering, super strings, normal distribution, and measuring ripples.

Fact 6: A professor at the University of Tokyo called Yasumasa Kanada took nearly 116 hours to evaluate 6,442,450,000 decimal places of pi.

Fact 7: Another fraction that is considered to be an approximation for pi is 355/113. A still more accurate fraction for pi is 104348/33215.

Fact 8: An irrational number is the one that is not expressed in the form of a/b, while ‘œa’ and ‘œb’ are integers. Pi is grouped under irrational numbers.

Fact 9: The first person to use pi was the Welshman William Jones in the year 1706. The circle periphery is described by the unit’s diameter.

Fact 10: A memory champion called Hideaki Tomoyori recalled pi’s value by memory to about 40,000 places in the period of 17 hours 21 minutes. This time includes the breaking period of 4 hours 15 minutes. He has performed this event on March 9-10, 1987. The event happened at the Tsukuba University Club House.

Fact 11: Another memory champion who has memorized pi was Hiroyoki Gotu. He remembered 42,000 decimal digits.

Fact 12: Â Feynman point is reached when there are six 9s Â seen at the 763rd position after the decimal.

Fact 13: One billion decimals of pi when printed will extend from New York City to the middle of Kansas.
