Pi day is celebrated each year on 14th March and to mark its importance, Emma Haruka Iwao from Japan has broken a Guinness World Record after she computed the value of Pi up to 31.4 trillion decimal places, 31,415,926,535,897 places to be exact.

The most difficult question teachers ask is, “define Pi”. Most of the students are startled by this question but it has a simple answer. Pie is ratio a circle’s circumference to its diameter. We usually use the value 3.14 or 22/7 as the value of Pi. People like us usually forget the next digit but people have managed to learn up to 70,000 digits which was done by Rajeev Meena from India.

Well, Indians are known for that, isn’t it? After all Aryabhatta, the founder of zero is from that nation only.

The record of computing digits was last under the name Peter Trueb who had computed up to almost 9 trillion digits.

It took 121 days, 170 terabytes of data, and 25 virtual machines for Google employee to calculate such a big number. Emma used Chudnovsky’s formula, an algorithm for calculating the digits of Pi at an incredibly fast rate.

While talking about completing it successfully, she said, “I feel very surprised, I am still trying to adjust to the reality. The world record has been really hard. There is no end with Pi, I would love to try with more digits.”

She even calculated the number of days it will take to say 31.4 trillion number and its answer is 332,064 days. She took the help of Google’s Compute engine to do the massive amount of calculation without any interruption.

If you plan to break this world record, you need to know it will take hundreds of days and an amount of data that you haven’t thought of before. It is not going to be such a biggie but whatever!
