## No closer to the end of pi?

yesterday, March 14, was Pi Day, a day that I neglected. So I'm trying to catch up by posting this:

Even After 31 Trillion Digits, We’re Still No Closer To The End Of Pi | FiveThirtyEight
On Thursday, Google announced that one of its employees, Emma Haruka Iwao, had found nearly 9 trillion new digits of pi, setting a new record. Humans have now calculated the never-ending number to 31,415,926,535,897 (get it?) — about 31.4 trillion — decimal places. It’s a Pi Day miracle!

Previously, we published a story about humans’ pursuit of pi’s infinite string of digits. To celebrate Pi Day, and the extra 9 trillion known digits, we’ve updated that story below.
That announcement: How Emma Haruka Iwao broke the Guinness World Records title for the most accurate value of pi
While I’ve been busy thinking about which flavor of pie I’m going to enjoy later today, Googler Emma Haruka Iwao has been busy using Google Compute Engine, powered by Google Cloud, to calculate the most accurate value of pi—ever. That’s 31,415,926,535,897 digits, to be exact. Emma used the power of the cloud for the task, making this the first time the cloud has been used for a pi calculation of this magnitude.

Here’s Emma’s recipe for what started out as a pie-in-the-sky idea to break a Guinness World Records title:

Step 1: Find inspiration for your calculation.
When Emma was 12 years old, she became fascinated with pi. ...

Step 2: Combine your ingredients.
To calculate pi, Emma used an application called y-cruncher on 25 Google Cloud virtual machines. ...

Step 3: Bake for four months.
Emma’s calculation took the virtual machines about 121 days to complete. ...

Step 4: Share a slice of your achievement.
Emma thinks there are a lot of mathematical problems out there to solve, and we’re just at the beginning of exploring how cloud computing can play a role. ...

It is mathematically impossible to find every digit, but it is still an interesting exercise in computing to see how many digits one can find.
