With this feat, Emma became the third woman to enter the Guinness World Record for calculating Pi up to large numbers.
Emma Haruka Iwao, a Google employee, just smashed the world record of calculating pi.
Emma spent four months working on the project in which she calculated pi to 31.4 trillion digits. She said Google Compute Engine helped reach the record-breaking number because it allowed the application to run without interruption from "hardware failures or underlying software maintenance". She told CNN that it was her childhood dream to create such a record. This is the first time the Pi calculation world record was ever broken in the cloud, and it breaks the most recent world record breakage, that of Peter Trueb in November of 2016.
According to Google, Iwao has been fascinated by pi since she was 12. Google and Yee broke Trueb's record by almost 9 trillion digits.
Pi, for people who've been out of school for long enough to forget, is the number given when you divide a circle's circumference (length around the outside) by its diameter (length across the middle).
Pi was first estimated thousands of years ago, and by the mid-20th century, mathematicians had calculated about 1,000 digits of the number, using a gear-driven calculator.
If there's a more exciting math concept than pi, then we've not heard of it.
Even with Google's infrastructure on her side, determining trillions of digits was no simple task. And for her and her colleagues at her Tokyo office, she adds, it was worth celebrating with "an actual pie".
