"The value of the number pi has been calculated to a new world record length of 31 trillion digits, far past the previous record of 22 trillion.
Emma Haruka Iwao, a Google employee from Japan, found the new digits with the help of the company's cloud computing service.

Pi is the number you get when you divide a circle's circumference by its diameter.

The first digits, 3.14, are well known but the number is infinitely long.
Extending the known sequence of digits in pi is very difficult because the number follows no set pattern."

What a great achievement for women!

I read this earlier, and I wasn't really sure whether I was impressed as the article didn't have any detail. She used a computer which means most of the credit needs to go to whoever designed it unless she came up with a new way to calculate pi (in which case that's what she should be famous for). The BBC have (understandably?) not explained what the calculation used was, but if her method was one of the usual infinite sums just with more memory and processing power, that's not at all impressive on her part. It would be like giving the driver credit for breaking the land speed record when all they did was stomp the accelerator. Then again perhaps she was the one who rigged it all together and that is impressive, but not in the mathematical way as implied.
