# Appreciating pi (not the edible variety)

7 Steps
Those who fear rows and rows of numbers, I recommend you to leave. Those who wonder what pi is so fascinating about, I recommend you to join me on this epic journey through pi.

EDIT: After having left this to rot for a few years, I have decided to correct some glaring typos. :D

## Step 1: Grab your slice of pi (and please don't eat it 'till we're done)

Now to get some pi to appreciate. There are a lot of websites offering up to 2 million digits of pi. Don't worry, as we are not going that deep. We are stopping at the 100th digit or so.

Here is a website you can go to get pi :

Here is a site to search pi digits :

Here are the 1st hundred decimal digits:

3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679

apparently of which (some) I have memorized. In the recent years after not actively revising I have forgotten some off the far end.

Just saying, pi is kinda incorrect. It's half of the real constant, 2pi, or tau. Look at tauday.com and see a whole manifesto on it.

Sorry for being such a party pooper. Pi is still cool, but not cool enough.

The string 12345678 occurs at position 186,557,266 counting from the first digit after the decimal point. The 3. is not counted.

Like my profile picture?   (the rating is 3.14 thats funny!)

just wishing you a happy π Day

Is it coincidence that the rating is 3.14? LOL!
dark sponge in reply to toothlesskillerMar 13, 2010. 8:22 PM
I'm not going to rate it simply so it can stay that way!

That is hilarious!

Hey, Pi is Einstein's Birthday too... Spooky huh?
Happens to be mine too... :-)
I know what I wan't my cake to look like now... Thanks!

I love pi =D

memorized pi to 61 decimal plaaces in pre-algebra one day.  i was *really* bored, but i still remember the digits!  the pi song helped.  it's on ytmnd.com or something.

YES, THIS IS VERY POINTLESS!!!!

Glad to see another pi-head. I memorized PI to 100 decimals in 1976 but never went any further. It's enough to count myself as a pi-head. Adrian
i got it to 37, and i thot *I* knew a lot...

i absolutely commend you dude

"8164" 8 squared is 64 and 16x4=64
rippinblaise in reply to SwishercutterMar 10, 2009. 6:28 PM
good observation in 6th grade i memorized the most digits of pi in my grade and won a banana cream pie i memorized 75 or something im in 8th grade now and i still remember 45 digits
yourcat says: Mar 10, 2009. 4:17 PM
I've memorized the Fibonacci series through 1597: 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 and powers of two through 262,144: 1 2 4 8 16 32 64 128 256 512 1,024 2,048 4,096 8,192 16,384 32,768 65,536 131,072 262,144

It always amazed me that the theoretical lift that is generated by a flat plate at any angle alpha is

L = 2*pi*alpha

Why 2*pi? where did that come from?
CameronSS in reply to trialexOct 31, 2007. 3:48 PM
I'm curious--what is the lift measured in? And is there an equally simple formula for the induced drag of said plate?
whatsisface in reply to CameronSSJul 12, 2008. 4:09 PM
Newtons I think, it's just an upward force.
trialex in reply to whatsisfaceJul 13, 2008. 2:56 PM
No, it's a co-efficient, it's non-dimensional
samv in reply to trialexDec 23, 2006. 4:26 PM
I'm not really sure what formula you refer to, but your calculating the surface between alpha and zero. 2*Pi (in radians) is actually 360°, so one circle. When you take a circle with radius 1, you measure the arc of 180° degrees, which is 3.1415...
trialex in reply to samvDec 23, 2006. 7:38 PM
Sorry I was being rhetorical... In aeronautics the first thing that you calculate the lift of is a flat plate, and the coefficient of lift genereated by a flat plate at an angle theta in radians is 2*pi*theta I just always found it amazing that pi works in all these different ways
