11-year-old Siddharth Arya Ravulaparthi broke Singapore’s most challenged personal record – the pi digits. He recited 2,856 digits in his home on 1 Nov 2022. The United World College student started memorising some pi digits when he was 9. And in the last one-and-half years he started working to break the national record. His parents are Ravi Ravulaparthi and Tejaswini.
