Happy Pi day

[interested_learner]

All of you have a happy international Pi day.

 

[Ki Man]

pi=3.13? may wanna check those calculations again =]

 

[d_leet]

It's not pi day yet..

 

[dontdisturbmycircles]

woohoo, pi day is finally here!! :uhh: :tongue: Can't wait til pi+0.01 day

 

[d_leet]

woohoo, pi day is finally here!! :uhh: :tongue: Can't wait til pi+0.01 day

Another hour and a half for me..

 

[dontdisturbmycircles]

Lol, I feel your pain.

 

[mattmns]

Hmmmm, $\pi$

 

[neutrino]

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

 

[hypatia]

pi day again already? Just where has the year gone? I didn't even get my pi day shopping done.

 

[radou]

Are there e and i days, too? :tongue2:

 

[neutrino]

Are there e and i days, too? :tongue2:

e-day: 27th January
i-day: e^(i*pi/2) = 27th Jan^(i*31st April/2) = :uhh:

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
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...

 

[radou]

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

 

[radou]

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:

 

[Math Is Hard]

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.

 

[MotolovCocktail]

I know the first 120 digits of pi:

3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651


whew!

thats all I know off the top of my head.

 

[humanino]

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 ?

Did you have a pi-digit-listing contest today? :tongue:

 

[Physics is Phun]

haha, our math building had free pie for all starting at 1:59 this afternoon.
and you can also buy pi day t-shirts for pi^2 dollars ($9.87)

 

[radou]

Did someone actually buy one of these? :rofl:

 

[SticksandStones]

Wow, 120 digits eh?
I know:
3.141592653597932384626

22 digits...
