This is way off topic, but we can’t resist. At the website of CBS News we read: Pi calculated to its ten trillionth digit.
The headline pretty much tells the story, but here are a few excerpts, with bold font added by us:
It took more than a year but a Japanese math enthusiast has used a a home PC to calculate the ten trillionth digit of pi, breaking a record set a couple of years ago by a supercomputer. … Shigeru Kondo was assisted in the feat by Northwestern University grad school student Alexander Yee, who wrote the software.
But why? According to Wikipedia’s article on Pi:
[T]he decimal representation of π truncated to 11 decimal places is good enough to estimate the circumference of any circle that fits inside the Earth with an error of less than one millimetre, and the decimal representation of π truncated to 39 decimal places is sufficient to estimate the circumference of any circle that fits in the observable universe with precision comparable to the radius of a hydrogen atom.
Well, it doesn’t have to be useful. It’s a quest, worthy for its own sake. One more excerpt:
During the course of the project, the temperature of the computer room climbed to nearly 104 Fahrenheit, or 40 Celsius. “We could dry the laundry immediately, but we had to pay 30,000 yen ($390) a month for electricity,” Kyodo News quoted Kondo’s wife, Yukiko, as saying.
See there? The project had a practical application after all — drying the laundry.
In case you’re those — shall we say — irrational types who is pi obsessed, we remind you that we’ve posted about pi before: Pi Day is Coming! That was in anticipation of 14 March, or 3-14 as some would write it. And don’t forget to mark your calendar, because the greatest Pi Day of the century is coming on 14 March of 2015 — that date will be 3-14-15.
For other crucial pi information, read about the Indiana Pi Bill. Yes, the legislators of that state almost enacted legislation to change the value of pi. And of course you know all about The Scriptural Value Of Pi.
When there’s more pi news, your Curmudgeon will bring it to you.
