Pi: Reciting Pi

Tom Morton attempts to recite over 20,000 digits of Pi, a mathematical constant representing the ratio of a circle's circumference to its diameter. Pi is an irrational number, meaning it cannot be exactly expressed as a fraction and is infinitely long. Archimedes first calculated Pi using geometry, and modern computers have extended this to 5 trillion digits. Despite this, only 38 decimal places are needed for precise calculations in the observable universe. Morton recited Pi to 12,850 digits, while the world record stands at 60,000 digits, highlighting the memory challenge Pi presents.
