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!

    14.3.2011, just a day like every else.

  3. I think I have about 500 million digits loaded, but I think IPKall cuts off calls after 2 hours. (At least based on the 2 calls coming in for almost exactly 2 hours)

    I listened to it for about 16 minutes (Google voice FTW…)

    I think I can see a pattern…just another 35 minutes to go…

    Free SIP DID number… Color me uninformed, but where do I get one of those??

  9. Lenny says:

    nvm.. before anyone says it I’ll say it to myself: RTFA

    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.

    Thank you for the video. I am at 2000 and have a good grasp of how to count in Japanese. Is that Japanese or Chinese?

  13. Renee says:

    All the cool people use tau!

  14. Trollicus says:

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

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

    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.

    @l0l:

    Good god. Over an hour of that? I would go insane 15 minutes in.

  16. RP says:

    Interestingly, if you call back it asks if you’d like to resume or start over.

    Maybe it’s using caller ID to recognize and remember callers?

    It was also Steak and Blowjob day… my personal favorite holiday :)

    Let it run for a good 10 minutes..

    In my world Pi is calculated with this formula: Pi=4/sqrt(Phi) where Phi is the golden ration, therefore
    4/sqrt(1.61803399..)=3.1446055098149202857483080831971635640926971699773107943065…

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

  21. The Pi Phone has a different number this year. (253)785-0990
