    I'd rather remember today as Einstein's birth anniversary, and wait till April 31st for pi-day. :rolleyes:

    The only problem is, how to decide if it's celebrated at 3:14 am or 3:14 pm.
  14. Mar 14, 2007 #13
    3.14 is taken care of by the date. So you celebrate it at 1:59:26(.5) in the morning (or in the afternoon if you don't use a 24-hour clock).
  15. Mar 14, 2007 #14
    I don't see it as a problem. We can precisely define pi's birth in this scheme, minutes second and everything, can't we ?

    I mean :
    month day hour minute sec...
    3 14 15 9 27

    now, maybe I see your objection :smile:
    why not :
    month day hour minute sec...
    3 1 1 9 2
    or :
    month day hour minute sec...
    3 14 1 59 27

    indeed, I assumed that one fills as much decimal places as possible at each step. Thus for instance I took 9 minutes, because 92 minutes exceeds 60=1h... This might be a little simplistic, or even unesthetical. But eh, why not celebrating on the first of march otherwise ?

    A more esthetical solution, would be to write down everthing in a decimal basis.

    I do use a 24-hour clock, but I would have thought we need to pick up 15:9:26

    this is highly debatable...

    Now you see it indeed is a sophisticated issue, gentlemen. :smile:

    Oh yes, and there's another issue. In my country, we write the day first, and then the month, so we have no pi day! Which proves that the pi day is a those-who-write-the-month-first-o-centric product. Down with it! :tongue2:

    Pi day at last! Can't wait to get up to campus at lunch time. Usually the math department sells yummy pie slices for a buck.

    And that's why I said that I would rather wait will April 31st. This is strictly a US-centric Pi-day. :biggrin:

    I know the first 120 digits of pi:



    thats all I know off the top of my head.
