Pi Phone Lulls You To Sleep With The Digits Of Pi

As you well know, today is March 14th – aka “Pi Day”.

Celebrated in math classrooms around the country, this truly is a celebration that belongs to the geeks. Here at Hack-a-Day, we too love Pi day, though we might not outwardly celebrate it with as much gusto as expressed by some of our readers.

[Chris Poole] is one Hack-a-Day fan who knows how to make the most of this mathematical holiday. He has put together a neat SIP-based phone service that reads Pi aloud to anyone who calls. He is running Asterisk in combination with Perl to read off the numbers, and is using a free SIP DID number to accept the calls. We gave it a shot earlier today, and were greeted by a gentle synthesized voice reading off the numbers of Pi. We’re not sure how many digits it is programmed to handle, as we stopped after about 20, so give him a call and let us know how many digits you make it through.

As a parting note, no Pi Day would be complete without a few obligatory Pi-related (albeit old) web comics and pastry concoctions, so here you go!

  1. There was an ad in the local paper about a restaurant (a steak house, IIRC) giving away free key lime pie today in celebration. I was surprised that anybody other than mathematicians and geeks celebrated. Alas, I did not go and get any.

  2. Hmm… so where is the vicious Tau Vs Pi debate?

    I expected the Mathematicians version of the Israeli Palestinian conflict to erupt.

    In this corner weighing ~ 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067982148086513282306647093844609550582231725359408128481117450284102701938521105559644622948954930381964428810975665933446128475648233786783165271201909145648566923460348610454326648213393607260249141273724587006606315588174881520920962829254091715364367892590360011330530548820466521384146951941511609 etc etc is the reigning champ Pi

    The challenger weighing twice as much: Tau

    Let’s get ready to number!

    Come out and shake and remember to stay in the bounded set of geometric points. and no hitting below the posulate.

  3. In my world Pi is calculated with this formula: Pi=4/sqrt(Phi) where Phi is the golden ration, therefore

    the result “new Pi” will change the last digits every time you add more digits to the phi in the formula.
