I think these were posted in the Science is Cool thread, but thought it would be cool to post a couple of videos that show the coolness of how pi pops out of seemingly nowhere, in the oddest, yet easiest to comprehend, places.

This one is amazing

Science makes the world go round... or was that math? Headache in 3..2..1..

Today is Pi Day, perhaps the most popular of geeky holidays. Hooray. But I’m here to tell you that Pi Day is wrong — or rather, the entire idea of pi as a mathematical concept is wrong.

It’s easy enough to see why people like Pi Day: the whole thing starts with a mathematical pun of sorts (The date is written as 3/14 in American notation. Pi starts with the digits 3.14. You get it.) It’s an easy, fun ritual to see how many digits you can pointlessly memorize of the famously never-ending, never-repeating number (even though 39 digits is more than sufficient for almost any calculations you’ll ever need). Plus pi sounds like pie, and who doesn’t like pie?

But here’s the thing: π as a number is bad, and therefore, so is the entire misguided day dedicated to its celebration. It’s a lot to take in, and I, too, was once like you: I was taught the virtues of pi for years, going back to Pi Day parties in middle school. But instead of pi, we should celebrate tau, an alternative circle constant referred to by the Greek letter τ that equals 2π, or approximately 6.28.

I’m not just making this up out of nowhere: the terribleness of pi as a constant was first proposed by mathematician Bob Palais in his article “π Is Wrong!” and later expounded upon in The Tau Manifesto by Michael Hartl, which serves as the basis for modern tauism. (Internet-famed mathemusician Vi Hart is also a major proponent of tau over pi, if you prefer your mathematical arguments in a more entertaining video form.)

But Palais and Hartl’s arguments both boil down to some basic math. Step back in time to when you first learned geometry and recall the simple origins: no matter what circle you’re using, if you divide the circumference of the circle by the diameter, you’ll get the same answer: an endless number, starting with the digits 3.14159265... (aka pi).

And right there is the fundamental flaw.
