There’ll be various educational and public celebrations around the world, and you can find details on the IDM website. ![]() So it’s a special day indeed for mathematicians, and late last year UNESCO voted to declare it the official International Day of Mathematics (IDM). Einstein’s mathematical insight led to a revolution in our understanding of reality, and ultimately to one of the greatest recent discoveries in science: gravity waves. Infinity is an awesome concept that we can never quite grasp, so it’s no wonder that π has such a tantalising imaginative pull.īut there’s even more to the significance of March 14, because it is also Albert Einstein’s birthday. The idea that you need a seemingly random infinite string of digits to “calculate” a tangible, finite circumference or area is strange, to say the least! That’s because π is an irrational number: it cannot be expressed as a fraction – as a ratio of whole numbers – and this means it doesn’t have a finite decimal form, or even an infinitely repeating one such as 0.33333… (= 1/3). Computers offer much more precision, with trillions more decimal places, but even these are approximations. My basic scientific calculator has 3.141592653 as its inbuilt value for π. Pi is famous as the mysterious number that relates the radius of a circle to its circumference and area, even though π itself slips through our fingers as soon as we try to pin it down. ![]() That’s because writing this date as 3/14 brings to mind the first three digits of π (pronounced pi). You’ve probably heard of “pi day”, informally celebrated in several countries on March 14. Ukrainian mathematician becomes the second female Fields Medal recipient.Pi Approximation Day – what’s behind the magic? (Hint maths not apples).Honouring forgotten women scientists, mathematicians, programmers and palaeontologists.Unfolding the secrets of origami structures.In reaching such lengths, the firm proves the flexibility and reliability of its infrastructure, which will help even more scientists continue pushing the envelope of scientific experimentation and discovery. Google Cloud’s accomplishment of calculating the first 100 trillion digits in the irrational number pi is about more than just the number. The entire calculation took 157 days, 23 hours, 31 minutes, and 7.651 seconds, and required 515 TB of the available 663 TB to store. The calculation began last year on Thursday, October 14th, at 12:45 am EDT, and ended on Monday, March 21st at 12:16 am in 2022. Yee created the program that calculated the 100 trillion digits of pi, called y-cruncher v0.8.8. ![]() How did Google Cloud calculate Pi to 100 trillion digits?Īccording to Google Cloud’s press release, “the underlying technology that made this possible is Compute Engine, Google Cloud’s secure and customizable compute service, and its several recent additions and improvements: the Compute Ending N2 machine family, 100 Gbps egress bandwidth, Google Virtual NIC, and balanced Persistent Disks.”Īlexander J. However, Google Cloud was not to be upstaged! This year, Google Cloud smashed last year’s record by adding a tremendous 100 trillion digits. Then, last year scientists from the University of Applied Sciences of the Grisons broke that incredible record by tacking on another 31.4 trillion digits, boosting the record to 62.8 trillion decimal places. Back in 2019, Google Cloud calculated pi out to an impressive 31.4 trillion digits, setting the world record. Thousands of years ago, the irrational number pi, with infinite digits, was discovered.
