Google sets new Guinness World Record on Pi Day

Pi dream: Googler sets record for most digits calculated

Google had the craziest way to celebrate Pi Day by making the most accurate Pi calculation till date. Rather than contenting herself with a slice of fruit in pastry, Google employee Emma Haruka Iwao has used the company's cloud computing technology to set a new record for calculating the value of pi.

Emma Haruka Iwao, a developer advocate at Google Cloud, has celebrated Pi Day (3/14) by setting a new Guinness World Record for calculations of the attractive mathematical constant, reaching a number with more than 31.4 trillion (ha!) digits. This is nearly 9 trillion digits more than the previous world record, which was set in November 2016 by Peter Trueb.

Since she was 12, Haruka Iwao has been fascinated by pi, the enigmatic mathematical constant defined as the ratio of a circle's circumference to its diameter.

Why it matters: This is the first time the Pi record has been set using a commercial cloud service and the first achieved using solid state drives.

One former British soldier will face charges over Bloody Sunday

She calculated it to 31,415,926,535,897 digits, which also happens to be the value of pi - 3.1415926535897.

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. This is the first time the cloud has been used to calculate Pi to this magnitude.

The world record for manually calculating pi is held by British mathematician William Shanks, who managed 527 digits without a computer. "But even if you don't work for Google, you can apply for various scholarships and programs to access computing resources", Iwao added. I would list it here but I suspect that many digits may break the website.

Previously, China was home to the world's two fastest supercomputers.
