Forget about Pi Day, Have a Happy Tau Day!


ViHart continues her crusade of adorable internet videos espousing the virtues of using Tau as a constant to define and derive the dimensions of a circle rather than Pi, because it just makes things more simple and clear. At least, it seem like it makes it more clear.

Well, I suppose either way, it’s an excuse to eat twice as much pie as on Pi Day.

    So. This video is not only entertaining and enlightening, but it is also a simple musical math trick. As she recites digits from the tao string, she’s singing the corresponding note in the scale in which she wrote the song.

    Let’s assume it’s a C major scale, she sings a “D” note every time she says the numeral “2,” an “A” every time she says the numeral “6,” and a high “C” every time she says the numeral “8.” So when she says “6.28″ she sings the 6th, 2nd, and 8th notes in the major scale.

    There are probably more layers to it, but that’s all I am able to share!

    Well more from the point of Pi, but this nice interactive demonstration shows how these number Tau are PI are formed.  http://www.visnos.com/demos/pi#launch in terms of the area and circumference of a circle. Enjoy!
