Pi Day: Google calculates most accurate value of Pi

Enlarge this image

By using its cloud infrastructure, Google set a new record for the most accurate value of pi.

"It was my childhood dream, a longtime dream, to break the world record for pi", the Osaka, Japan-based developer and Google Cloud advocate tells CNN Business. The new record was announced on March 14, or 3.14, which is known as Pi day because the first three digits of the number are 3,1, and 4.

The previous record was 22.4 trillion set by Peter Trueb in 2016.

J&J hit with $29M verdict in California talc case
The plaintiff, Terry Leavitt , said she regularly used two J&J products in the 1960s and '70s containing talc. J&J attorneys asserted in court that there's no conclusive evidence talc caused Leavitt's mesothelioma .


Running the calculation on the cloud gives the mathematically curious a major upgrade in convenience, Google said.

Her former professor and one time world record holder for pi, Daisuke Takahashi, helped her with advice and technical strategies. "And I learned some people use computers to calculate millions and billions of digits of pi".

Iwao's calculation took 121 days to finish and needed 25 virtual machines. And Ms Iwao said she had been fascinated by the number since she had been a child. In less than an hour and for as little as $40/day, you can copy the snapshots, work on the results, and dispose of the computation resources. While you are Googling for sweet deals on actual pies, let's not forget that pi, or π, is a mathematical number to begin with, one that describes the ratio of a circle's circumference to its diameter, no matter the circle's size.

If you'd like to participate in the Pi Day fun, there's a Google Cloud Showcase Pi Day art-maker up for the tapping right this minute. Pi is used in engineering, physics, supercomputing and space exploration - because its value can be used in calculations for waves, circles and cylinders. It's an irrational number that continues infinitely without repetition. It is significantly used in geometrical calculations.

Android Q Beta 1 officially announced
If you are on your Pixel smartphone, it is still possible to activate this mode, but of course it won't be optimal. Instead of releasing the first beta only for developers, Google is letting anyone sign up and install the beta .
