Google broke Pi world record, requests 31.4-trillion works of art

World Record 31.4 Trillion Digits of Pi Calculated By Google Scientist

Today is 14 March, also known as Pi Day (due to being written as 3/14 in the United States).

Emma spent four months working on the project in which she calculated pi to 31.4 trillion digits.

A Google employee has broken the world record for calculating Pi to the highest number of digits - at 31 trillion. This is nearly 9 trillion digits more than the previous world record, which was set in November 2016 by Peter Trueb. That's when she first downloaded software to calculate pi on her PC. Pi is an irrational and transcendental number and it continues infinitely without repetition or pattern.

The value of pi was calculated using the y-cruncher application on 25 Google Cloud virtual machines and required a whopping 170 terabytes of data to complete.

But the value of Pi, the ratio of a circle's circumference to its diameter, has new meaning on this Pi Day. Iwao said in the announcement that's she's been fascinated with pi since she was 12- and never imagined breaking the Guinness World Record. The semi-official holiday for the unique number is celebrated by eating actual pies.

Most people will be familiar with the first few digits of pi from geometry class (3.14.).

"It was my childhood dream, a longtime dream, to break the world record for pi", Iwao said.

This feat was achieved by Emma Haruka Iwao, a Cloud Developer Advocate at Google. Emma further explains that this was possible using a Pi-benchmark, y-cruncher which was developed by Alexander J. Yee on Google Compute Engine virtual machine cluster. "At the time, the world record holders were Yasumasa Kanada and Daisuke Takahashi, who are Japanese, so it was really relatable for me growing up in Japan". Researchers who wanted to peer into a data set that large used to have to ship physical hard drives to one another, but now they can access the company's results remotely. During the entire time it took for calculations, the Google Cloud server were kept switched on to avoid any interruptions. "Hopefully we can do an even bigger computation in the future".
