Australian researchers have done the impossible -- theyve found the sixty-trillionth binary digit of Pi-squared! The calculation would have taken a single computer processor unit (CPU) 1,500 years to calculate, but scientists from IBM and the University of Newcastle managed to complete this work in just a few months on IBM's "BlueGene/P" supercomputer, which is designed to run continuously at one quadrillion calculations per second.
Their work was based on a mathematical formula discovered a decade ago in part by the Department of Energy's David H. Bailey, the Chief Technologist of the Computational Research Department at the Lawrence Berkeley National Laboratory. The Australian team took Baileys program, which ran on a single PC processor, and made it run faster and in parallel on thousands of independent processors.
"What is interesting in these computations is that until just a few years ago, it was widely believed that such mathematical objects were forever beyond the reach of human reasoning or machine computation," Bailey said.
"Once again we see the utter futility in placing limits on human ingenuity and technology."

I’ve only calculated PI to 1 million places using an old program and a 486 computer. It took a while.
Thank goodness! I have been up half the night with insomnia worrying about Pi squared. Now I can go back to sleep :-)
/s
You should double check your math. That millionth place is a bitch.
Base 13. God has 13 fingers.
Start over? :)
Pi are too squared
These are the same type of folks who believe they can predict “CLIMATE”.....aka useless information.
I believe Pi is only an approximate to start with...so this means nothing.
Ken & Brad got smoked.
Tell me that this bad boy runs entirely on green energy and I'll be impressed...If it uses more carbon energy than my ice maker we have a problem.
They should give up on this. It won’t get Obama removed from office.
WOW. The suspense is killing me. Hello, ZERØ, no?

You might not like hearing this very much, but it might not be the most savvy political move to say that you live in *ahem* Germany while choosing as your screen name, the founder of the KKK.
And yes, I was the one who wrote you about that long ago, after having read your 'About' page: you modified it slightly to put more emphasis on his late-in-life conversion to Christianity; but even that won't allay lefties' suspicions.
As for Google? They have ways of making you talk.
And your Wi-Fi sings like a canary.
Cheers!
That is an awesome answer. lol.
Does anyone know why they are seeking the digits of pi squared instead of just the digits for pi itself???
Does pi squared have some signifigance more so then pi.
Once I get past fingers and toes, I don’t see much point in continuing......
There are exact formulas. They do not have closed forms, and they converge very slowly.
As I recall, one of them is [4 - 4/3 + 4/5 - 4/7......]
After 10000 terms, MS Works gives 3.141492654, good to only 3 digits.
I will agree that on cheap computers, the least significant digits cannot be trusted.
