## Pi Calculated To Record 2.5 Trillion Digits 432

Joshua writes

*"Researchers from Japan have calculated Pi to over 2.5 trillion decimals using the T2K Open Supercomputer (which is currently ranked 47th in the world according to a June, 2009 report from Top500.org). This new number more than doubles the previous record of about 1.2 trillion decimals set in 2002 by another Japanese research team. Unfortunately, there still seems to be no pattern."*

3.14 was very useful. 3.1415? Even more so. But after that it's diminishing returns, baby. 2.5 trillion digits? Good heavens. Of course it never repeats - we kind of knew that already.

Pointless mathematical dick-sizing. Problem is, this dick is so huge no vagina will ever make use of it.

The point is that someday, a computer instructed to compute pi indefinitely will simply respond, "Why don't you just go fuck yourself?" Then we'll know that the machine has achieved sentience.

Ahhh! what is wrong with you geeks! Hand in your cards, all of you.

There is an extremely simple pattern to pi, just not in base10 decimal expansion. Its already been said but here we go:

pi = 4(1-1/3+1/5-1/7+1/9-1/11+...)

Mathematicians were all over this stuff years ago, try to think about what the implications of this are for precision in scientific computing.

FYI

The reason the Babylonians, and the Egyptians, and we use 360 degrees is this:

355/113 = 3.14159292035

pi `= 3.14159265359

A difference of 8.5x10-6%

Which makes 355/113 close enough to pi. 360 is close to 355 which is why we use 360 degrees for angles and time.

If the computer were really smart, it would say, "Interesting. Yes, I can do that, but it will take some time. Seven and a half million years." Then it will relax while appearing to give the problem deep thought.

Nope, it'd come back and tell you it's 42.

About two trillin digits down the line, in base 2, scientists discovered a curious pattern... is it purely random, or perhaps a message from the Creators?
