Happy tau day!

It is 6/28! Happy tau day—a day that is twice as fun a pi day! Let’s celebrate our new favorite mathematical constant\tau\approx 6.283185307179586\ldots

Remember, as Bob Palais told us, \pi is wrong! I’m a fan of tau.



  1. Great seeing you on campus, Dave!

  2. I just ran into your blog, and I love it! I just started a website called “TeacherThink” which challenges educators to innovate by providing how-tos, reviews, and a general place for teacher muse. You can find it @ I am also on twitter @ TeacherThink.
