π = 6.2831… ? Have we got it wrong?


Recently reading a book by Steve mould “The Element In the Room”, he proposes that our definition of pi was a mistake, and instead it should have been double it’s value.

How can this be?, surely someone would have noticed. Well, it all comes down to definition. Pi is defined as the ratio between the diameter of a circle to the circumference. However, it could have just as easily be defined as the ratio of the radius of a circle divided by the diameter, and when that happens, many mathematical formulas become simplified.

Here’s a great video of Steve Mould arguing his case for Tau, or the double pi constant.
