In the world of memory world records and mental ability achievements, few accomplishments capture global attention as powerfully as extraordinary feats performed at a young age. Hero Vietson, an 11-year-old prodigy from El Centro, California, USA, has earned international recognition by setting a remarkable world record for memorizing digits of pi, demonstrating exceptional cognitive strength, focus, and discipline.
World Record Achievement: 7,700 Digits of Pi Recited Blindfolded
On 15 December 2025, Hero Vietson successfully memorized and orally recited 7,700 digits of pi (π) while blindfolded, establishing a distinguished world record in memory and mental ability. This achievement positions him among the youngest individuals in the world to accomplish such a high-volume pi recitation under controlled conditions.
The record attempt was conducted with strict adherence to global verification standards. Hero remained blindfolded throughout the performance, and the entire attempt was recorded on video with a verified 360-degree view, ensuring transparency, accuracy, and the absence of external assistance.
Verified Evidence and Record Authentication
A defining strength of this world record lies in its comprehensive documentation. In addition to the primary record video, Hero’s preparation journey is supported by an exceptional archive of over 110 sequential videos, each capturing incremental progress in memorizing pi digits.
This methodical documentation confirms that the achievement was the result of long-term discipline, consistency, and structured training, not a one-time performance. Such detailed evidence is a key requirement in world record certification and strengthens the credibility of the claim.
