Enjoy a piece of the Pi Pie.  ;D

If you ask a scientist what pi equals he'll tell you it equals 3.14159....
If you ask a mathematician what pi equals and he'll tell you pi equals the circumference of a circle divided by its diameter....
If you ask an Engineer what pi equals he'll say "Pi? Well, it's about 3, but we'll call it 4 just to be safe."...

And if you ask a kid what pi is, he'll ask if he can have ice cream with it!...

...I'm here all week.....g'nite!

Here's a link to Pi to the 10,000th digit.  ;D

I'm certain that it is a fascinating read...........BUT, I think I will wait for the movie to come out...

LOL!  ;D

I don't blame ya' HH.  Perhaps it's only fascinating to me and other math/technical sorts.  I think I pointed this out once upon a time somewhere else, but it seems that the fascination with calculating pi out to so many digits is just something we humans are interested in doing.  It really serves no purpose to any sort of scientific or engineering topics.  From Wikipedia:

For example, the decimal representation of π truncated to 11 decimal places is good enough to estimate the circumference of any circle that fits inside the earth with an error of less than one millimetre, and the decimal representation of π truncated to 39 decimal places is sufficient to estimate the circumference of any circle that fits in the observable universe with precision comparable to the radius of a hydrogen atom.

So you can calculate the circumference of the earth to within one millimeter using pi to 11 digits, and the circumference of any circle in the observable universe to the radius of a hydrogen atom using 39 digits.  So calculating from 40 ---> infinity is simply an academic exercise.  :yes:

Probably TMI for some.  ;D

I have a niece who has a PI tattoo!


Guess it runs in the family!

:biggrin:

Wow!  That's interesting.  Any idea what prompted her to get the Pi tattoo?

But to answer the question, she was a math major at St. Johns.

Ah!  That explains it.  I have a degree in math as well.  :biggrin:
