Google employee calculates pi to record 31 trillion digits The Verge

A Google employee from Japan has set a brand new international record for the number of digits of pi calculated. Emma Haruka Iwao, who works as a cloud developer propose at Google, calculated pi to 31,415,926,535,897 digits, smashing the previous file of twenty-two,459,157,718,361 digits set lower back in2019.

Although Iwao turned into using the same y-cruncher application to calculate pi because the previous report holder, her gain lay in the use of Google’s cloud-primarily based compute engine. The 31 trillion digits of pi took 25 digital machines 121 days to calculate. In contrast, the previous document holder, Peter Trueb, used only a unmarried speedy pc, albeit one prepared with two dozen 6TB difficult drives to handle the big dataset that became produced. His calculation simplest took 105 days to complete.

Outside of bragging rights, the 9 trillion more digits are not likely to have too many actual-world uses. NASA only makes use of around 15 digits of pi to send rockets into space, and measuring the seen Universe’s circumference to the precision of a single atom could take simply 40 digits.

At any charge, if my colleague Chaim is to be believed, then pi sucks besides, and we ought to all be using tau as a substitute. Thankfully, tau is simply double pi, so it should be quite easy for Google to spin up its cloud servers yet again and get to work doubling its new 31 trillion-digit number.

Google has produced a more in-depth blog post explaining how the mathematics of the calculation worked. Meanwhile, in case you need to apply the entire period of pi for your self, then Google has posted the digits as disk snapshots to allow anybody to get entry to them. (Details of the way to do so are contained within the equal submit.)

Let's block commercials! (Why?)
