Vi Hart - A Song About A Circle Constant lyrics

When you want to make a circle, how is it done? Well, you probably will start with the radius 1 Then use a compa**, or a string, and use a paper or the ground And if the radius is 1, how far did it go around? It's tau! 6.28 It's tau! 6.28318530717958 If you pick a certain distance, and you pick a certain spot And you put the two together, then what have you got? It makes a very special shape, and now you are the inventor If you take all of the points a certain distance from your center And you've got a great collection, and it is a great invention And it makes a lovely circle, well depending on dimension Cause there's 1, 2, 3, then there's 4 and even more But for a circle, how much circle's there if you take the distance and compare? It's tau! 6.28 It's tau! 6.28318530717958 647692528 I know what you are thinking, what about that other guy? The one that's sometimes pronounced pee, and sometimes pronounced pie? I mean it's fine if you are building, but does not belong in math All the equations make more sense when you use taw, you use taff! And while you get the same answer no matter which way We get further from truth when we obscure what we say You know that math makes sense when it's beautiful and pure So please don't make it ugly with your bad notation and awful curriculum Use tau! 6.28 Use tau! 6.28318530717958 647692528 667665590 05768 394338 7 [987] 550211
