Do you know Pi?

[Richard Wallace]

pi = 3.1415926...

355/113 = 3.1415929... This easily remembered fraction differs from the correct value of pi by less than 90 parts per billion; that's close enough for any engineering activity I've ever been directly involved with.

but you still have to memorize 6 digits to get the fraction, and then you have to divide it out

to memorize to 90 parts per billion you only have to memorize 8 digits!

I have memorized Pi - I memorized the symbol - its the key on my calculator that looks like two TT 's run together, and thats all I need to know!

BTW, Akira Haraguchi has stepped over the line and caused an unforeseeable amount of grief for millions of men all over the world. I can hear it already

[wife] IF 60 year old Akira Haraguchi can remember Pi to 100,000 digits then why cant you remember my FOUR DIGIT BIRTHDAY! [/wife]

Yeah... I read about this in the news. My math teacher says that if we memorize like 50 or 100 he'll give us extra credit...what about 100,000? Hmm...

I had the same extra credit deal in my geometry class four years ago, where you can get extra credit if you memorize pi to 50 decimal spots. It's a shame all I can remember is 3.1415926535897932384626433832795028841 off the top of my head.

I think the box that you Pi people would think outside of has totally decomposed.

isnt there a program that lets you search for stuff like your birth day, phone number, or SSI number in PI, to see how far it you have to go to find the 1st instance of it?

now I wondering if (314) 159-2653 is someones phone number?

If so it's in my area (STL) ... trying now ... nope.

Guess 159 is not a valid prefix.

Yes, you can search through the first 200 million digits of Pi here.

sqrt( 6 * sum( 1/(n^2), n, 1, infinity) )

OOPS, I've said too much!

[Lil' Lavery]

Pi=C/(2r)
or
Pi=A/(r^2)

I win


Now, who can tell me Phi?

.5(1+(5)^.5) = phi

...But I prefer to truncate the .618... part so I can count, phi, e, pi as 1, 2, 3, respectively..

...come to think of it, those minor truncations and roundings I've made may be the source of most of my problems in math this semester...

Phi is the larger solution of x - 1 = 1/x, often called the Golden Mean.

So is it pronounced "fee" or "fie" ?

Next question: who can tell me "fo" ? (Too easy. It's the integer successor of three.)

Then who can tell me "fum" ?

[verbal abuse166]

still I'd have to say I like pi more (probably just because once i was board and memorized 42 digits of it) as well as board I'm too lazy to chant them off, but pi was like my symbol in my old school, so i never forgot the digits because everyone always had me recite them

Fum is solving math problems, as in "I love Math! It is a lot of Fum!"
