Not even slightly sewing related -- but it's Tau Day!!!
my contribution to this festive occasion: key lime* and pecan
"What?" you ask, "what could this be?" Ever heard of Pi Day? March 14th (3.14) when all the math enthusiasts go out for pie? Well, Tau is 2Pi -- and thus June 28th. However, it is more than just a day to eat two pies (although that is an important part of the celebration) its actually a much more sensible constant that makes geometry make a LOT more sense. To find the circumference of a circle one multiples pi by the diameter .... but no one ever uses diameters, we use the radius ... which makes it 2*pi*r. Not the biggest deal, but if you've ever tried to map the sine wave of a unit circle, you know the insanity that is pi. But tau... tau*radius = circumference, and BAM geometry works in the clean, simple and elegant way it is supposed to. Check out the video for a really good explanation of just whats going on here. Amaze your friends! Astound you enemies! Overwhelm random passer-by! ('Cause its 2 * Pi!) (I crack me up.)
*made with key-limes and decorated with persian ones. Don't worry. I know what's what :)
