Pi – the circumference of a circle over diameter – is a number that, while being functionally infinite, also happens to be a constant in every circle ever. The first digits, 3.14, are well known but the number is infinitely long, and Pi day celebrates the long history of this fantastic number, and the long journey science has taken (and is still on) to seek it’s end.
Today, Emma Haruka Iwao, a Google employee from Japan, found the new digits with the help of the company’s cloud computing service, and calculated the value of the number pi to a new world record length of 31 trillion digits, far past the previous record of 22 trillion – to put that into context, it would take 332,064 years to read that number of digits out loud! That’s quite an achievement, Emma – you certainly deserve a piece of Pi to celebrate!
