Yahoo! researcher breaks Pi record in finding the two-quadrillionth digit
A new record has been broken in the field of mathematics by a team of researchers and a super computer working on creating a very long version of Pi. The team, led by Nicholas Sze of Yahoo!, used the company's Hadoop cloud computing tech to break the previous record by more than double, creating the longest Pi yet. Back in January, the record was set at 2.7 trillion digits using a standard, full mathematical calculation of the problem, but the Hadoop route was different. It set different parts of the computer to work on different sections of the problem, cutting up the problem into manageable-sized pieces (as shown in the formula in the image above). We're sure this record won't survive long enough for anyone to write a song about it, but it's quite an achievement all the same.
