Jaipur resident Sunil Kumar Sharma (21) received the Square Root of Two World Ranking certificate on Monday for creating world record of memorising maximum post-decimal digits of the value of square root two on June 3 this year. Square Root of Two World Ranking is part of Pi World Ranking List, a body which registers records of memorizing highest number of values of Pi and square root of two.
Sharma, who hails from village Mansharampura, spoke 5,710 digits of the value of square root two in an hour and 42 minutes. In pulling off the feat, he bettered his own May-19 record when he had spoken 5,632 digits in an hour and 31 minutes. Earlier to his May-19 record, Mark Umile of USA had held the record for almost a decade by speaking 5,544 digits of the value in two hours and seven minutes.
In addition, Sharma has also made the world record by saying 243 digits of square root two in one minute at an event organized by India Book of records on June 24 this year. The previous record was by a European who had spoken 222 digits in three minutes and eight seconds on March 22, 2015.
Sharma, who is doing Shiksha Shastri (BEd) from Jagadguru Ramanadacharya Rajasthan Sanskrit University, says he was very forgetful in his childhood and his friends would make fun of him for this. He left studies because of depression but later started with Sanskrit which greatly helped him improve his memory.
Sharma claims that he was able to do so because he used to memorise the digits through visualisation.
Currently he is writing a motivational book and hopes to write a book on memory techniques later in life.
