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 holds the current unofficial world record for reciting 10,000 digits of pi in 16 hours, starting at 9:00 a.m. (16:28 GMT) on October 3, 2006. He equaled his previous record of 83,500 digits by nightfall and then continued until stopping with digit number 100,000 at 1:28 a.m. on October 4, 2006.
On 7 March 2020, he recalled 24,063 digits of pi, setting a new personal, Swedish, and European record. [5] His aim was to recall the first 100,000 digits but he made a mistake on the 24,064th. Three days later he became the first person to pass the "Olympus Mons of Memory Tests", being tested on samples from the first 100,000 digits.
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.
Verification of the binary digits: 64 hours (Bellard formula), 66 hours (BBP formula) Verification of the binary digits were done simultaneously on two separate computers during the main computation. Both computed 32 hexadecimal digits ending with the 4,152,410,118,610th. [51] 90 days 5,000,000,000,000 = 5 × 10 12: 17 October 2011 Shigeru ...
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.
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 .
The 2002 record for digits of π, 1,241,100,000,000, was obtained by Yasumasa Kanada of Tokyo University. The calculation was performed on a 64-node Hitachi supercomputer with 1 terabyte of main memory, performing 2 trillion operations per second. The following two equations were both used:
