FRIDAY IS PI  DAY:
March 14th (3.14), is  day. It's an occasion to _celebrate_
(http://www.teachpi.org/)  one of the most compelling and  mysterious 
constants of Nature.
_Pi_ (http://en.wikipedia.org/wiki/Pi)  appears in equations  describing the
orbits of planets, the colors of auroras, the structure of DNA.  The value
of  is woven into the fabric of life, the universe and  ... _everything_
(http://en.wikipedia.org/wiki/File:Life,_The_Universe_and_Everything_cover.jpg)
.
Humans have _struggled_
(http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Pi_chronology.html) 
to  calculate  for thousands of years. Divide the
circumference of a  circle by its diameter; the ratio is .  Sounds simple,
but the devil is in the digits. While the value of  is finite (a smidgen 
more
than 3), the decimal number is  infinitely long:

Supercomputers have succeeded in calculating more than  2700 billion digits
and they're still crunching. The weirdest  way to compute : throw_needles_
(http://www.angelfire.com/wa/hurben/buff.html)  at a table  or _frozen  hot
dogs_ (http://www.wikihow.com/Calculate-Pi-by-Throwing-Frozen-Hot-Dogs)  on
the floor. Party  time!
