Mathematical Cat Fight (Happy Tau Day — June 28th)
When I went to school a zillion years ago, using Pi was a given in math class. So I was astonished to learn that some mathematicians favor using Tau instead. What’s the difference? While Pi’s value is 3.14 plus an endless bunch of post-decimal digits, Tau’s value is double Pi at 6.28 (plus its own post-decimal digits*.) And while Pi is celebrated on March 14th, math fans commemorate Tau on June 28th.
I figured that since I’ve already written Pi a limerick ode in its honor, Tau deserves the same treatment:
Mathematical Cat Fight (Limerick)
By Madeleine Begun Kane
It seems Pi has a challenger — Wow!
The name of its rival is Tau!
Its value is twice
That of Pi — oh how nice!
“2 Pi R” becomes “Tau R.” Meow!
Happy Tau Day!
