Conclusion Introduction Yes, it's the day after Tau Day, and I'm already back at it. Last summer, I had a two-day posting stretch around Tau Day in order to cover another book, and I'm doing the same this year. I want to get through as much of Peterik's book as possible this summer. My Tweets I finally got back on Twitter yesterday, and I actually participated in a mini-conversation. (I kept on tweeting less when I realized that many of my tweets were not being read.) It was Tau Day, of course. But someone tweeted that a better Tau Day would be July 44th. To me, this would be more in analogy with Pi Approximation Day on July 22nd (22/7), as opposed to Pi Day itself on March 14th. So I tweeted that July 44th would be Tau Approximation Day. And here's his response -- he l

It is not defined in the U of Chicago text -- if it were, it would have appeared in Section 8-8, as follows: Definition: tau =  C / r , where  C  is the circumference and  r  the radius of a circle. Now the text tells us that  C  = 2pi *  r , so that  C / r  = 2pi. Therefore, we conclude that tau = 2pi. The decimal value of this constant is approximately 6.283185307..., or 6.28 to two decimal places. Thu
