It’s Pi Day - 3/14! There’s an article on the BBC website celebrating the mathematical ratio: > **[BBC News - 3.14 and the rest](http://news.bbc.co.uk/2/hi/uk_news/magazine/7296224.stm)** > > It's Pi Day, a celebration of the mathematical ratio man has been trying to unlock for millennia. But why are we driven? The article also says: Pi shows up everywhere. In mathematics, pi appears in many fundamental equations that have nothing to do with circles. In science, pi is inextricable from measuring everything from ocean waves to economic statistics. Pi is found in the very measurements of the Great Pyramid at Giza. And if you divide the length of a river from source to mouth across a gently sloping plane by its direct length “as the crow flies”, you’ll find pi. Does anyone have any more details on these non-circular applications of pi? ---

Well, anything with pi in it is related to circles since pi is related to circles. But in a lot of places the connection to circles is non-obvious. My favorite is the Euler identity, which is e[sup]pi\*i[/sup] = -1 I don’t quite understand what the article is trying to say about rivers. I think they’re talking about viewing a river as the hypotenuse of a right triangle. In that case, the ratio of the height of the river to the length can be found by trigonometry, and the trig functions are all functions of pi (and each other.) ---

Never heard of “Pi Day”. More importantly, it’s [Steak And BJ Day](http://www.steakandbjday.com/)! The male equivalent of Valentine’s Day! Yeeehaw! ---

Every October 23rd, my high school would celebrate Mole Day. My chemistry teacher’s preferred festivity was igniting small balloons filled with exactly one mole of H[sub]2[/sub]. ---

[QUOTE=Least Original User Name Ever] Nope. It’s Steak and Blowjob Day. Get the memo, dammit. [/QUOTE] The Steak and a Blow Job people should find another day, so as to not sully pi, in all it’s beautiful irrationality. To celebrate pi day, I’ve serving pie to everyone that works here during the afternoon break today. Steak and a Blow Job Day may or may not be celebrated tonight, depending on how full and sluggish **Z.R. Test** and I are from eating the leftover pie. ---

Since there’s already an existing Pi day thread [here](http://boards.straightdope.com/sdmb/showthread.php?t=459711), I’ll go ahead and close this one.
