Tau is better than Pi.  Tau being equal to 2 Pi.

Examples of why include circumference of circles (using a pie) where you
can use the radius times tau...the radius being a more typical way to
specify a circle than the diameter, radians, where parts of the circle
don't involve dividing by two, and sin plots where the X axis has
simpler values, like T/2, T/3, T/4, than when you use Pi.

Counterexamples exist, but were not covered...such as the area of a
circle where Pi works better than Tau.

Other than the pie crust part of the lesson, that's about it I think.
