The only problem is, how to decide if it's celebrated at 3:14 am or 3:14 pm.

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).

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...

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:

so, what is the accuracy with which you can calculate the circumference of the galaxy, supposing you know it's diameter with a precision equivalent to that of the size of the proton ? :rolleyes:

:wink:
