Do you know Pi?

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.

When I got really bored in math class back in 7th grade I memorised 100 digits. Wish I got extra credit for that!

Ha ha ha... yeah, if you have enough time (or willpower, or focus) to memorize 25+ digits of Pi, the box doesn't exist for you to think outside of.

My friends phone number is (excluding area code so you don't all call him) 223-1419. It's realy funny because any time any of us need to call anyone it's like... hmm i can't remeber anyones number. Wait a sec call dave everyone knows daves number it's 22 pi.

There was an attempt to legislate the value of Pi in Indiana in 1897. Bill #246 would have legally established Pi to be equal to 3.2! The Bill, was introduced by Edwin Goodwin, M.D., with a provision that the State of Indiana could use his copyrighted solution free of charge, but outsiders would have to pay him a royalty! With the backing of the Indiana House Committee on Education, the Bill passed the Indiana House 67-0. Fortunately, a math professor from Purdue (Professor Waldo) was able to convince the State Senators that the bill should be killed. Further consideration of the Bill was postponed indefinitely, and it never appeared in the Indiana Assembly again.

Full details (with a link to the text of the Bill) can be found at: Indiana Pi

P.S. Try working through the "proof" offered in Section 1 and 2 of the bill. It's convoluted and (of course) wrong...

1897 was the beginnings of the industrial revolution. It would have been interesting if every circular object made in Indiana did not match measurements from the rest of the world, for example, if 1" diameter bearings were actually 1.05" diameter, because they had to make the circumference match the legal definition of Pi in that state?

And how many universities would there be in the state, if they were required to teach incorrect mathematics?

Don't those AndyMark traction wheels seem a little oversized? Could it be???

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

OOPS, I've said too much!

[Lil' Lavery]

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

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

[KenWittlief]

given how we memorize everything else, is there a PI song ?

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