It is Pi Day in the United States tomorrow; everywhere else it is 14.3.2015. It is a particularly strange bit of American exceptionalism, especially since you call your national holiday the 4th of July. Tomorrow is the 14th of March. that’s day first, then month. And all the nerds out there who love Pi Day should know that their beloved computers and iPhones are even more sensible and go year month day and that it’s really 20150314. People are making a big deal about this year being a one in a hundred chance because it is 2015 so that tomorrow morning for a second it will be 3.141592653 but remember Y2K? Billions were spent to change computers from the last two numbers to all four numbers so even if you go month day year tomorrow is 314201592653 or all the planes will fall out of the sky. And that ain’t pi.
But I like Pi, I like anything that promotes math and education, and I like pie, even if it is illegal in my local Toronto St. Clair West subway station. Insane traffic to a post on 20 Awesome Projects for Raspberry Pi Microcomputers pays my salary. So I am not going to diss pi. I am going to celebrate Pi Day in absentia from 14032015-land to the north and eat a good french cheese quiche pi at precisely 9:26:53 Saturday morning in honor of math and science and nerds.
In the meantime, here is a roundup of past Pi stories on TreeHugger.
So why is Pi Day green? We have justified it by noting that "As Bucky Fuller would remind you, a circle encloses the maximum area per unit of perimeter, a sphere the maximum volume. It is theoretically the most efficient form," and we are all about efficiency. That's why we start with the Picycle, created by Tang Yau Hoong; it combines the efficiency (and round-ness) of the bike with Pi.
Last year our roundup included this important Pi Chart, among other stories.
