Later computers calculated pi to extraordinary numbers of digits (2.7 trillion as of August 2010), [4] and people began memorizing more and more of the output. The world record for the number of digits memorized has exploded since the mid-1990s, and it stood at 100,000 as of October 2006. [ 6 ]
Haraguchi uses a system he developed, which assigns kana symbols to numbers, allowing for the memorization of pi as a collection of stories. The same system was developed by Lewis Carroll to assign letters from the alphabet to numbers, and creating stories to memorize numbers. This system preceded the system above which developed.
A sequence of six consecutive nines occurs in the decimal representation of the number pi (π), starting at the 762nd decimal place. [1] [2] It has become famous because of the mathematical coincidence, and because of the idea that one could memorize the digits of π up to that point, and then suggest that π is rational.
Pi Day is celebrated each year on March 14 because the date's numbers, 3-1-4 match the first three digits of pi, the never-ending mathematical number. "I love that it is so nerdy.
In 1977, after losing interest in engineering, Mahadevan set to memorize substantial parts of pi. On 5 July 1981, he recited from memory the first 31,811 digits of pi. [1] This secured him a place in the 1984 Guinness Book of World Records, and he has been featured on Larry King Live and Reader's Digest. [2]
The last 100 decimal digits of the latest world record computation are: [1] 7034341087 5351110672 0525610978 1945263024 9604509887 5683914937 4658179610 2004394122 9823988073 3622511852 Graph showing how the record precision of numerical approximations to pi measured in decimal places (depicted on a logarithmic scale), evolved in human history.
Reversing the digits to modern-day usage of descending order of decimal places, we get 314159265358979324 which is the value of pi (π) to 17 decimal places, except the last digit might be rounded off to 4. This verse encrypts the value of pi (π) up to 31 decimal places.
It was used in the world record calculations of 2.7 trillion digits of π in December 2009, [3] 10 trillion digits in October 2011, [4] [5] 22.4 trillion digits in November 2016, [6] 31.4 trillion digits in September 2018–January 2019, [7] 50 trillion digits on January 29, 2020, [8] 62.8 trillion digits on August 14, 2021, [9] 100 trillion ...
