Pi or Tau ?
Apparently ,Pi is ( not wrong ), but less efficient and useful than Mathematicians have thought for thousands of years .
I , personally , did NOT celebrate Tau day --6/28--I DO remember telling Pythagorus that it seemed silly to use 1/2 of a function -but the prick refused to listen ...he was as stubborn as Leonitus-I TOLD Leonitus to kill that hunchback as his existence was against all the spartans believed ..I prefer using an Abacus myself .

"When measuring angles, mathematicians don't use degrees, they use radians," Houston enthusiastically told Life's Little Mysteries, a sister site to LiveScience. "There are 2pi radians in a circle. This means one quarter of a circle corresponds to half of pi. That is, one quarter corresponds to a half. That's crazy. Similarly, three quarters of a circle is three halves of pi. Three quarters corresponds to three halves!" [A Real Pie Chart: America's Favorite Pies]
"Let's now use tau," he continued. "One quarter of a circle is one quarter of tau. One quarter corresponds to one quarter! Isn't that sensible and easy to remember? Similarly, three quarters of a circle is three quarters of tau." Making tau equal to the full angular turn through a circle, he said, is "so easy and would prevent math, physics and engineering students from making silly errors."
A better teaching tool
Aside from preventing errors, as Palais

That went so far over my head that I couldn't even hear the whoosh!

Quote:

"I know it will be called blasphemy by some, but I believe that pi is wrong."

That's the opening line of a watershed essay written in 2001 by mathematician Bob Palais of the University of Utah. In "Pi is Wrong!" Palais argued that, for thousands of years, humans have been focusing their attention and adulation on the wrong mathematical constant.

Two times pi, not pi itself, is the truly sacred number of the circle, Palais contended. We should be celebrating and symbolizing the value that is equal to approximately 6.28 ? the ratio of a circle's circumference to its radius ? and not to the 3.14'ish ratio of its circumference to its diameter (a largely irrelevant property in geometry).

You think I memorized 250k digits of pi just so they could double it for kicks? Helllllllll no.
