If you should ever need to remember the first 7 numbers of pi, here's a little trick (I have been mocked for this but they'll all bow to it in the end! (...Maybe))

'How I wish I could calculate pi' -Straight, or 'How I wish I could calculate pie' -to round it up.
How- 3 I- 1 wish 4 I-1 could-5 calculate-9 pi-2/pie-3
3.141592/3

Cunning ey?! :P
clever, but to be honest my calculator does it just fine...

why is Pi called Pi?
It's the Greek version of P, short for perimeter.

i don't need to use some rhyme to memorise "pi", i already know it 115 decimal places. no joke. 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823.

don't tell me im a sado kos you watch, when all the computers are destroyed one day and people in the countries will be aksing the nearest person as to what pi is to the maximum decimal places.

Has to be e^i(pi)=-1 The best equation around and proves there is a God
I thought of that one too.
Someone in my Maths class memorised about 120 digits. Anyone got that little book with a million in? It was in our school library.

Knowing pi to 115 decimal places is all well and good (I know about 100 myself), but let's face it, when will we ever need that many digits?
I read somewhere that with just 42 decimal places of pi, you could calculate the area of the universe to within the size of a single proton.
And I once downloaded a file which had pi to a million digits. Can't remember where I got it, though.

Weebl and Bob? One of the funniest things in existence!

I seem to remember hearing that one too. Somewhere, perhaps, with the sort of article that says how may tens of billions of digits they've calculated...

how do you know this????

ln i = 1 + i(2n-1)pi

how do you know this????
ln z = ln |z| + i arg z

sorry i got that bit wrong: ln i = i (2n-1)pi

Why? Who needs to know pi to that many digits?

But is there any reason for pi to be that accurate?

Did you know that melissa joan hart - or sabrina - can recall pi to 400 decimal places?
Mostly i like mince pie! but 3.141592654 often comes in useful.

None whatsoever, but its a peculiar number, and some people are obsessed with it. And it crops up everywhere. There was one guy, I think, who basically devoted his life to designing better, faster computers... in order to better calculate pi.

I only know that pie divides into pieces of equal deliciousness that I can just munch away on! Chicken and Sweetcorn, Steak and Kidney, Shepherd's, Cottage, mmm!!! Not tried hair pie yet...

Been done before hasn't it...
