Haraguchi holds the current unofficial world record for reciting 100,000 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.
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 ]
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 .
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 ...
[117] [118] The record, always relying on an arctan series, was broken repeatedly (3089 digits in 1955, [119] 7,480 digits in 1957; 10,000 digits in 1958; 100,000 digits in 1961) until 1 million digits were reached in 1973. [117] Two additional developments around 1980 once again accelerated the ability to compute π.
YouTube Kids has faced criticism from advocacy groups, particularly the Fairplay Organization, for concerns surrounding the app's use of commercial advertising, as well as algorithmic suggestions of videos that may be inappropriate for the app's target audience, as the app has been associated with a controversy surrounding disturbing or violent ...
