Pi day

[RecycleMichael]

Today is Pi day.

The mathmatical number for calculating the area of a circle is 3.14159.

On 3-14 (today) at 1:59 pm...everybody eat some pie.

3.1407?  []

My favorite palindrome of the day, "I prefer pi."

[sgrizzle]

Ahh.. my old college fraternity.. I Aituh Pi

[TheArtist]

An old Okie saying.    Pie are round, cornbread are square. []

Sounds good to me.

my favorite types of pi are hot, cold and more.

Aah yes... But can you tell me how the numerical value was discovered.....?

Good for one slice of Buttermilk Pie...!

Why yes, yes  I can.  Archimedes used ever more complex geometric shapes to approximate pie starting with an octagon.  After that the methods turned to calculus to get more precise and I get lost in the strange symbols that are somewhere beyond the +-*/= on my keyboard.

Now, behold, PI in all its glory!  (well, 1mil places of its glory);

its 1:59 on my watch.

dangit, Im downtown with no pi at 1:59!!!


argh!

[cannon_fodder]

I have a donut.  1:59 server time.

Damn flood control, if I miss 1:59!

Oh man... it wouldn't let me post because I hurried here after posting elsewhere.  Made me and I missed it.  

/me goes off to cry.

As early as the 19th century BC, Babylonian mathematicians were using pi = 25/8, which is almost within 0.5% of the exact value.

An Egyptian scribe named Ahmes wrote the oldest known text to give an approximate value for pi;. The Rhind Mathematical Papyrus dates from the Egyptian Second Intermediate Period — though Ahmes stated that he copied a Middle Kingdom papyrus (i.e. from before 1650 BC) — and describes the value in such a way that the result obtained comes out to 256/81, which is approximately 3.16.

The Indian astronomer Yajnavalkya gave astronomical calculations in the Shatapatha Brahmana (c. 9th century BC) that led to a fractional approximation of pi = 339/108 (which equals 3.13888..., which is correct to two decimal places when rounded).

In the third century BC, Archimedes proved the sharp inequalities 3 + 10/71 < pi < 3 + 1/7, by means of regular 96-gons. (Differentiating the arctangent function leads to a simple modern proof that indeed 3 + 1/7 exceeds pi.)

The Chinese mathematician Liu Hui in AD 263 computed pi to 3.141014, which is correct to 3 decimal places, though he suggested that 3.14 was a good enough approximation.

Pretty much the same version I was taught......

It has been many years ago.... Seems there was a Teacher, that I had, that threw in something regarding the distance around the base of the pyramids and the height and mass etc..

My brother was the Math fanatic.

One "Buttermilk Moon Pie" for the Moonenite...!
