Blue Gene/P Reaches Sixty-Trillionth of Pi Squared

Reader Dr.Who notes that an Australian research team using IBM's Blue Gene/P supercomputer has calculated the sixty-trillionth binary digit of Pi-squared, a task which took several months of processing. Snipping from the article, the Dr. writes: "'A value of Pi to 40 digits would be more than enough to compute the circumference of the Milky Way galaxy to an error less than the size of a proton.' The article goes on to cite use of computationally complex algorithms to detect errors in computer hardware. The article references a blog which has more background. Disclaimers: I attended graduate school at U.C. Berkeley. I am presently employed by a software company that sells an infrastructure product named PI."

    From the blurb:

    Oh, I expected the sentence to end with, "...and I still don't know why the fuck anyone cares about a number this long."

    I'm going to the bar. Who's with me?

    Well, it's a quantum supercomputer, so...yes.

    I know all of them. I just don't know which order they go in.

    "How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics!" There you go, Pi to 14 digits in an easy to remember package. Count the letters in each word to get the right digits.
