Recalling 70,000 digits in the mathematical value of Pi

Mathematics is a difficult subject for many students, while a mathematics examination is a nightmare for many, but not for 25-year-old Rajveer Meena, an alumnus of VIT University, Vellore.

He seemed to enjoy his attempt at breaking a Guinness Record by recalling from memory 70,000 digits, which is the mathematical value of ‘Pi’ in the shortest time, which he made at a hall on the VIT campus here on Saturday.

Sitting blindfolded, Meena recalled 70,000 digits in 9 hours and seven minutes, breaking the earlier record of recalling the highest number of digits (67,890) in the shortest time (24 hours 8 minutes), set by Chao Lo of Shanxi Province in China in 2005. His feat, which was recorded and documented in the presence of 13 witnesses (comprising representatives from the media, NGOs and social organisations, and professionals) and 20 professors from the VIT and other colleges, has been sent to the Guinness Book of Records, London, U.K. for adjudication.

A native of Morchala village in Sawaimadhopur district in Rajasthan, Meena first got interested in memory feats when he was not able to perform well in studies in school.

He developed his own method by remembering mathematical number sequences by associating an imaginary colour, an event or an object with those sequences. This helped him in his school exams.

As a student of VIT in 2011, Meena had made a record in the Limca Book of Records by recalling 1,125 random mobile numbers from his memory, breaking an earlier record set by Nishant of Andhra Pradesh who recalled 840 random digits from memory.
