An employee of Google has set a new record for calculating the number of Pi

Google employee Emma Haruko Iwao calculated the value of Pi to 31 trillion decimal places. Previously, the number "Pi" was known only to the 22 trillionth digit.

Now mankind knows more. Ivao used one of the Google services. The calculations required 20 terabytes of memory, 25 virtual machines and 121 day.

Pi is the ratio of the diameter of a circle to its length. The first few digits - 3,142 - are known to everyone, but the number "pi" is infinite, and the sequence of numbers is completely unpredictable.

Pi is used in many sciences, engineering, and supercomputer construction. It can be used to calculate wave ranges, circumferences and volumes of cylindrical figures.

Calculating Pi is a popular activity among mathematicians. Iwao became fascinated by this number even when she was a child.

“I’m very surprised,” Iwao comments on her achievement. “I’m still trying to get used to it. Breaking the world record was very difficult,” she says.

She hopes that she will be able to beat her own record.

“Pi has no end.” I would really like to try to add numbers,” she said.

The space agency NASA on Thursday explained how pi is used in calculations. With it you can:

• Calculate the parachute area for the descent of the rover to Mars;
• Calculate how many rectangular photos you need to create a complete map of the planet;
• Calculate the moment of deceleration of the spacecraft in such a way as to bring it into orbit.

“Pi is important for more than just measuring circles. This number is used in a variety of calculations - from the period of a pendulum to the flexibility of a rod,” comments mathematician Matt Parker.

“Modern mathematics, physics, engineering and technology would not work without Pi,” he says.

In 2010, Nicholas Sze calculated that the twenty-quadrillionth digit after the decimal point would be zero. He used Yahoo's cloud service - a calculation that would have taken 500 years on a regular computer.
