You don’t need to be a mathematician to appreciate Pi: Children everywhere can tell you it’s 3.14. But now experts are arguing that Pi, which references the ratio of a circle’s circumference to its diameter, be replaced with a new constant known as Tau. Not because pi is wrong, per se – its value is still correct – but because it is the wrong figure to associate with a circle’s properties.
Pi simply isn’t the most natural number that we should associate with a circle. The proper number is 2Pi, or Tau which is approximately 6.28.
The number 2Pi is an important part of many formulas and equations, meaning that using Tau as the main circle constant would simplify things and could even make subjects like calculus easier to understand.
Mathematicians are campaigning for textbooks to be changed.
