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:


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

Step 2: Getting Started...

Here are the first 20 digits. Don't they look pretty?


I got a little too carried away and had to remove an extra 8 digits.

Step 3: Warmed Up?

I actually forgot a little something :

pi digits 15 to 25

32384626433 (look at the 1st picture)

Ok, lets carry on...

pi digits 21 to 30

2643383279 (2nd pic)

Step 4: Getting Hungry for More?

the next 20:


I decided to show more at one go because there are some patterns spread out here.

Step 5: Feel a Little Twitchy?

pi digits 51-70


Is your stomach growling for more?

Step 6: You Are Quite Done...

The last 30 :


Whoa! What a big bite!

Step 7: Reflections

What were those for? For fun. Don't take them too seriously. Enjoy life. Takeaway a pi-zza (haha). Sit and eat. Forget all these. You will find it difficult at first.

Then come back to this instructable and repeat. Hopefully this has made your day.

Returning a few years later to look at your own Instructable is always fun :D
Just saying, pi is kinda incorrect. It's half of the real constant, 2pi, or tau. Look at <a href="http://tauday.com" rel="nofollow">tauday.com</a> and see a whole manifesto on it.<br> <br> 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.<br><br>The string and surrounding digits:<br><br>72269200957811705289 12345678 05029135885957638876
Its&nbsp;a Palindrome not a Pandrilome :)
thats wat he said palindrome
pi tastes good
Like my profile picture?&nbsp;&nbsp; (the rating is 3.14 thats funny!)
just wishing you a happy &pi; Day<br />
Is it coincidence that the rating is 3.14? LOL!
I'm not going to rate it simply so it can stay that way!
&nbsp;OMFGWTFBBQ!<br /> <br /> That is hilarious!<br />
Hey, Pi is Einstein's Birthday too... Spooky huh?<br /> Happens to be mine too... :-)<br /> I know what I wan't my cake to look like now... Thanks!
&nbsp;dude, that's my sister's b-day
I love pi =D<br />
memorized pi to 61 decimal plaaces in pre-algebra one day.&nbsp; i was *really* bored, but i still remember the digits!&nbsp; the pi song helped.&nbsp; it's on ytmnd.com or something.
this is all i know: 3.14159265358979323846323846264332643383279502884197169399375105820974944592307816406286208998. my momwill give me ten dollars if i remember all one hundred
I only memorized 3.1415926535897 ...so far
hehehe... Still have a ways to go xD 3.14159265358979323846264338327950288419716939937510582097494459230781640862089986280348253421170679. The other comment si posted are wrong. Lol.
i got<br /> 3.141592653589793238426433&nbsp;
Now I know 3.14159265358979323846264338327950 OMG! I CAN'T RECITE WITH 8TH GRADERS SINGING! :O I will do this later....
doh ! i thought it was: 3.14159265441 ! i was wrong so ill start again :) when im on the throne ;)
<strong>YOU FROGOT TO USE BOLD!!!!!</strong><br/>
<strong>YOU FORGOT TO USE SPELL CHECK!!!!</strong><br/>
<strong>WHO CARES?!?!?!?!?!?!?</strong><br/><br/><sup>On the other hand, could this get any more pointless?</sup><br/>
I do!!!!<br/><br/><em>lol, jk<em><strong></strong></em></em><br/>
'<em><strong>EVERYONE THAT HAS A LIFE CARES!</strong></em><br/>
<strong>I HAZ NOT GOT ONE OF THOSE WHAT IS IT?</strong><br/><br/> but in all seriousness... this is a pretty pointless conversation...<br/>
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...<br/><br/>i absolutely commend you dude<br/>
&quot;8164&quot; 8 squared is 64 and 16x4=64<br/>
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
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<br/><br/>L = 2*pi*alpha<br/><br/>Why 2*pi? where did that come from?<br/>
I'm curious--what is the lift measured in? And is there an equally simple formula for the induced drag of said plate?
Newtons I think, it's just an upward force.
No, it's a co-efficient, it's non-dimensional
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...
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
I didn't expect such an overwhelming response.<br/><br/>I may do <em>e</em> or phi soon...I may even try <em>i</em> (haha).<br/><br/>I chose pi because I have memorised 110+ digits of it.<br/>
curious question: how old are you? it takes a really good memory to do that
Currently 14. The 100 digits was done at around 12.
isn't phi like 1.58 or something?
P.S. I won a memory contest with pi... 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679
phi = square root of 5 - 0.5 :-)<br/><br/>Do e, its the only one that you can't do on a basic scientific calculator :-)<br/>
I was under the impression that you press: 1, INV, Ln
o cool, we just had pi day a few days ago, umm i wasnt plannign on entering the contest, but i did a few, just by listening to a bunch of people saying em, so here goes 3.14159265358979323846264338 i think i had a lil more but i guess i forgot pi PIE/PI FTW!
Are you like one of those freaks that can actually remeber past 3.14159?
i'm not a freak, nut i know this far: 3.14159265358979323846323846264332643383279502884197169399375105820974944592307816406286208998. not sure how many digiits it is though
