Tau Day

One of the major
contributions Archimedes made to mathematics was his method for
approximating the value of Pi, the ratio of the
circumference of
a circle to its diameter. There is now an online movement to
celebrate Tau, the number you get when you use a circle's
radius instead. Tau is approximately 6.28, instead of the familiar
constant Pi, which is 3.14. There is much opinion and
controversy surrounding this new movement. Nevertheless, Tau Day is celebrated on June 28.
Here are some Tau resources for you to explore.
