The Tau of Pi

April 14, 2011

I came across this interesting article – The Tau Manifesto.

It’s proposed that the stalwart constant of geometry – Pi (π) – be replaced by a new, more natural constant – Tau (τ) – which is simply Circumference/Radius and is so equivalent to 2π. They make quite a convincing argument as to why this should be the case.

Those multiples of 2π in equations always made me twitchy… and now I realise why!
