Unfortunately, the Tao Manifesto is full of selective bias in order to convince readers of the benefits of τ over π. They pinpoint formulas that contain 2π while ignoring other formulas that do not.
If you happen to be in the St Louis area and like pie, my aunt is selling Pi day pies today. Fresh made and delivered.
I can attest to the deliciousness of her pies. ;)
Are There Things-in-Themselves
Dr. Paul Carus
Title: The Surd of Metaphysics
without heirs to her fathers was gathered,
Here at the auctioneer's
"things-in-themselves" will be sold.
The relation between the circumference and the diameter of
the circle is quite definite and concrete, but if expressed of a
numerical fraction its value can only be approximated, admitting
of an infinite progress in accuracy. So the world is determinable
and science is reliable in spite of the fact that her work can never
be finished, and however much we progress and advance in the
solution of life's problem, we can never reach the end. But this
condition of things is not depressive to a healthy mind. On the
contrary, it is an elevating idea that the source of knowledge will
never run dry, and that the waters of life are inexhaustible.

Well, I'll just imagine one.
Even if the date's not ISO 8601 it's still 03/14/2013? And how does the 159265359.... work 15:92:65 ?
I guess this is semi relevant http://www.xkcd.com/397/
I have a friend we nicknamed Pi. His "hobby" at school used to be memorizing the digits after the decimal point in Pi. I remember at some point in time he could recite a few thousand. Never got the point though.
It is about a guy that can recite pi to incredible lengths. Very good documentary.
Mathematical constants, great food and sexual pleasure, not to mention presents. I am truly blessed!
