It's PI Day...Everyone Celebrate The Greatest Mathematical Number

PI is the most recognizable number to non-mathematicians. It is ratio of any circle's circumference to its diameter and has been calculated to 5 trillion digits.

PI is easy to remember. Here it is to 50 digits. Memorize just 3 to 5 digits at a time and you'll get it.

The Guinness-recognized record for remembered digits of PI is 67,890 digits, held by Lu Chao, a 24-year-old graduate student from China. It took him 24 hours and 4 minutes to recite to the 67,890th decimal place without an error.

Damn! That's awesome!

Nobel prize winning poet Wisława Szymborska wrote a poem about PI:

The caravan of digits that is pi
does not stop at the edge of the page,
but runs off the table and into the air,
over the wall, a leaf, a bird's nest, the clouds, straight into the sky,
through all the bloatedness and bottomlessness.
Oh how short, all but mouse-like is the comet's tail!

Here's another one:
Just for fun...

Consider humble pi. It is a number never ending.
It never repeats itself as its value keeps ascending.
Based upon a circle, many men have tried
to calculate the ratio of its width to its outside.
It is called irrational because it can not be made a fraction.
The challenge of its nature has been a call to action.
The number pi has played a role in every life on earth.
From physics to statistics, its always proved its worth.
The tires that you ride on, the table where you dine,
little pi was there throughout its concept and design.
Humble pi is constant - its been a great addition
and quietly serves us each day without recognition.
If you can not appreciate why I hold this number high,
then shame! It is you that should be eating humble pie.

-- Ken Johnson



So everyone celebrate PI Day. At 3:14 pm start reciting numbers and amaze your friends, family and co-workers.
