Just in case you weren't convinced that Silicon Valley is the geekiest place in the United States, this should seal the deal. A group of skywriters took to the skies over the San Francisco Bay Area yesterday, and spelled out the value of Pi to 1,000 places.
For anyone who skipped out on sixth grade math, Pi is the ratio of a circle's diameter to its circumference, and is most often simply quoted as 3.14. That's just an approximation, and the true figure can be calculated to an endless number of decimal places. Last year, someone calculated Pi out to 10 trillion places, which is probably more accuracy than most people need. Still, it's good to know that someone has done it.
The "Pi In The Sky" skywriting event required five planes flying in sync in a loop over 100 miles long to fit it all in. The piece was created by an artist called "Ishky," working with Stamen Design, for the 2012 Zero1 Biennial.
The real bummer is that, like all skywriting, Pi In The Sky was a very temporary creation. In fact, by the time the crew had finished the 1,000th digit, the 3.14 at the start was already long gone to the winds.
Check out the video below, where a bunch of office workers in Fremont try to figure out what all the numbers mean. At first they think it's a phone number, but then it keeps going and going. (The video is mildly NSFW — there's some swearing.)
