Pi is wrong

'τau = 2π. That's the first thing you need to know. The second is that tau is a whole lot more friendly to use than the awkward pi. Instead of defining a circle by its diamater, it allows you to define it by its radius, making it as equally transcendental and irrational as pi is.'

Duncan Geere continues, 'For the full details of why tau is far tastier than pi, you can watch the video above or read the Tau Manifesto, written by Michael Hartl on Tau Day (28 June) 2010. The idea actually originates, however, with an article titled π is wrong!, written by Bob Palais in the Mathematical Intelligencer during 2001. You'll probably need a maths A-level, or equivalent, to fully appreciate its elegance, but if you don't have one then don't let that put you off.' Read the whole article at Wired >>
