Swiss researchers at the University of Applied Sciences Graubünden this week claimed a new world record for calculating the number of digits of pi – a staggering 62.8 trillion figures. By my estimate, if these digits were printed out they would fill every book in the British Library ten times over. The researchers’ feat of arithmetic took 108 days and 9 hours to complete, and dwarfs the previous record of 50 trillion figures set in January 2020. But why do we care? The mathematical constant pi (π) is the ratio of a circle’s circumference to its diameter, and is approximately…
