New Pi Record
Apparently Shigeru Kondo accomplished this feat using a home-built computer that worked non-stop for 90 days. Apart from this dramatic triumph for mathematical hobbyists (Kondo is a systems analyst for a food company), the article contains the following two excellent lines:
“Calculating a more accurate pi, which is believed to go on forever, has been a challenge for scholars for thousands of years.” Believed to go on forever? Is the reporter some kind of mathematical agnostic?
And this, from Kondo himself: “I really want to praise my computer, which calculated continuously for three months without complaint.” Credit where credit is due, I suppose.
It is interesting to note that, while 5 trillion is indeed the new record for consecutive digits of pi, researchers at Yahoo were able to compute digits that are much farther out than that; they just don’t know all the digits that lead up to it!
