quadrillionth The Two Bit of π is 0!

In order to test the effectiveness of certain technologies has achieved a new record for calculating binary digits-in-the number Pi. Has been SZE, Tsz Wo (Nicholas)

This research company Yahoo has estimated 2,000 trillion digit of pi - 2.10 -. 15

Its calculation model is based on the MapReduce developed by Google, which divides the problems into smaller ones, then combining the results for solving complex mathematical problems.

Instead of calculating the full number-such as was done in the last record of August, "Sze team uses a formula that allows you to calculate" chunks "of pi. In particular, they found the 256 values \u200b\u200branging from position to the number 2,000,000,000,000,252 1,999,999,999,999,997.

(When π is Represented in decimal, hexadecimal and binary, we respectivamente have

π	=	3.1415926535 8979323846 2643383279 ...
	=	3.24 3F 6A88 85A308D3 13198A2E ...
	=	11.00100100 00111111 01101010 ...

Bit position is counted starting after the radix point. For example, the eight bits starting at the ninth bit position are 00111111 in binary or, equivalently, 3F in hexadecimal.)

computers to calculate decimal places of Pi, and also put to work in support of scientific advances, there programs scientists that allow anonymous citizens - for example you-work selflessly in providing scientific projects of the resources of your computer - when not being used or is working with an application that requires little power ( as Word) -, thereby receiving data that solve calculations are then sent to a data center. The only prerequisite: being connected to the Internet.

One is Ibercivis with more than 25,000 volunteers who have downloaded the software in www.ibercivis.es . Thanks to them streamline calculations, for now, eleven scientific research projects of drugs (for cancer, Parkinson's, Alzheimer's) fusion physics, study materials, optical research and predictions about climate change, among other subjects. Are investigations that require millions of tests and virtual simulations whose calculations require a supercomputer machine.


Ibercivis usually has the computing power of an average of between 8,000 and 10,000 volunteers . Speeding up the progress of investigations. Tens of millions of computer hours of data each year. A cheap way to build intelligent computing power that would otherwise be wasted. A union of people doing science. ! Beautiful!.
