The Guinness-recognized number of remembered digits of π is 70,000 digits, held by Rajveer Meena, a 21-year-old BTech holder from India, at the VIT University, Vellore, India, on 21 March 2015. Rajveer wore a blindfold throughout the entire recall, which took nearly 10 hours. Earlier, the record was held by Lu Chao. He had recited post decimal Pi values up to 67,890 digits in 24 hours and 7 minutes in 2005. Haraguchi views the memorization of pi as the religion of the universe, and as an expression of his lifelong quest for eternal truth.
