- inactive, on 10/12/2007, -59/+174PI IS EXACTLY THREE!
I'm sorry it had to come to that, but now that I have your attention... - S1ngular1ty1, on 10/12/2007, -7/+81I prefer visualizing pi as π = circumference / diameter
- doom.md, on 10/12/2007, -5/+76Math is magic
- MioTheGreat, on 10/12/2007, -4/+61The top ln(e^10) reasons why e pwns pi:
http://www.pen.k12.va.us/Div/Winchester/jhhs/math/humor/epi.html
10) e is easier to spell than pi.
9) pi ~= 3.14 while e ~=2.718281828459045.
8) The character for e can be found on a keyboard, but pi sure can't.
7) Everybody fights for their piece of the pie.
6) ln(pi^1) is a really nasty number, but ln(e^1) = 1.
5) e is used in calculus while pi is used in baby geometry.
4) 'e' is the most commonly picked vowel in Wheel of Fortune.
3) e stands for Euler's Number, pi doesn't stand for squat.
2) You don't need to know Greek to be able to use e.
1) You can't confuse e with a food product. - NanoStuff, on 10/12/2007, -9/+60"PI IS EXACTLY THREE!

Did noone else catch this obscure Simpsons reference? - inactive, on 10/12/2007, -4/+48What do you mean we can't imagine it. The very fact that we have a word to conceptualize it means that we can.
- d00ley, on 10/12/2007, -2/+45Infinity isn't a quantity.
- inactive, on 10/12/2007, -11/+53Burn the math teachers!
- inactive, on 10/12/2007, -4/+42Very cool animation, but didn't everyone learn this in their geometry class?
- error792, on 10/12/2007, -1/+39Why does π get all the attention? What about e? In my opinion, Euler's Formula makes e pwn π.
- kingkilr, on 10/12/2007, -1/+38e is cool, but pi has this sorta aura, you learn it as a kid and you still don't really know what it is . . . i dunno it also tastes good
- SundayTrain, on 10/12/2007, -5/+39If you don’t eat your meat, you can’t have any pudding (Or Pie)
- TinFoil209, on 10/12/2007, -1/+34Sorry to rob the top but here is the best way to use the power of pi in your benefit, A BAR BET!!!! Check this video from college humor!

No dark sarcasm in the classroom
Teachers leave them kids alone - MioTheGreat, on 10/12/2007, -1/+27"phi * 1/phi = 1 "
NO WAY! A number divided by itself is 1?! I can't believe it! Where's my calculator? - chrisxkelley, on 10/12/2007, -18/+44@strain:
"We don't need no education [...]"
yes you do... you just used a double negative :) - MinaSulo, on 10/12/2007, -2/+25I busted out a ruler and found the graphic to be ~0.0145552 off. Buried as inaccurate.

"5) e is used in calculus while pi is used in baby geometry."
Someone's never heard of trigonometry.
Radians > Degrees - manixrock, on 10/12/2007, -0/+17The Absurdity of Calculating Pi to Trillions of Digits:
"If one were to find the circumference of a circle the size of the known universe, requiring that the circumference be accurate to within the radius of one proton only 39 decimal places of Pi would be necessary."
Think about that the next time you visit a site boasting 5 trillion decimals for PI :) - inactive, on 10/12/2007, -5/+22As a 4th year mathematics student I don't understand the obsession with all these constants to be honest.

http://www.digg.com/videos_educational/Insane_80_s_tv_show_about_PI - randovaro, on 10/12/2007, -0/+17Someone showed me a good approximation to Pi of 355/113. They liked it because only three integers in the numerator and denominator yielded an approximation to Pi to several decimal places. Certainly accurate enough for most practical purposes...
- Caleb83, on 10/12/2007, -1/+16Phi is pretty interesting too
http://en.wikipedia.org/wiki/Golden_ratio - grumpyrain, on 10/12/2007, -0/+15"Here is a better approximation:"
Why not just say: 31415926535897932384626433832795/1000000000000000000000000000000
The point was that 355 and 113 gives 6 dp. btw, this was discovered by Zu Chongzhi in the 5th Century. - 5thWall, on 10/12/2007, -0/+14But Euler's formula has e and Pi. e ^ ( i * Pi ) = -1
- Takteek, on 10/12/2007, -0/+14"6) ln(pi^1) is a really nasty number, but ln(e^1) = 1"... Is it just me or is that really dumb?
That's like saying "log base pi (e^1) is a really nasty number, but log base pi (pi^1) = 1".... - KillerJ59J, on 10/12/2007, -0/+13No, we don't care.
- luckytalisman, on 10/12/2007, -1/+13Ever want to visualize and HEAR what prime numbers look and would sound like if placed on a chromatic scale? Check it out:

Pretty cool if you ask me. - inactive, on 10/12/2007, -1/+12http://pi.ytmnd.com
- spinningobo, on 10/12/2007, -1/+12They did that to show that the diameter * 3.14 = the circumference .

- DeFex, on 10/12/2007, -0/+9They should have made the wheel an actual pie instead.

Pi to one MILLION decimal places - opiniastrous, on 10/12/2007, -0/+8@D3Koy.
On a related note, no-one here cares about myspace. It's just about as close as you can get to physically recreating faeces in digital form.
Secondly, you clearly just stole that animation from the guy who made it (http://en.wikipedia.org/wiki/User:John_Reid) and then made out as if you'd had it on your myspace page before that. WHAT A ***** HACK! I couldn't have believed it if I hadn't seen it with my own eyes... - inactive, on 10/12/2007, -1/+9These rational approximations you guys have listed above are just convergents of the continued fraction expansion of pi.
The good thing about the convergents is that they provide the "best" approximation. What exactly does "best" mean? This is essentially saying that to get closer to the irrational than the given convergent, we need to make the denominator larger than the denominator of the convergent, i.e. the rational needs to be more complex than the convergent. In other words, the convergents p_n/q_n give the best possible approximation to an irrational number out of all the rationals
whose complexity does not exceed q_n.
The convergents also converge to the irrational quite rapidly. Here are the first few convergents of pi.
3, 22/7, 333/106, 355/113, 103993/33012, etc.
you can show that if A is the irrational number. and p_n/q_n the nth convergent. Then |A- (p_n/q_n)| < 1/(q_n)^2.
you can also show a stronger result that for any two consecutive convergents at least one satisfies |A-p_n/q_n| < 1/[2(q_n)^2]. - inactive, on 10/12/2007, -6/+13@Software2
Nice quote. Looks like it went over most people's heads.
edit.. beat - Bleeblaow, on 10/12/2007, -3/+10I got an idea guys:
Take a class in abstract algebra or topology or any other proof-based mathematics topic and you'll probably stop getting into pissing contests on the internet over how smart you are for taking calculus, because you'll realize that a retarded monkey can pass a calculus class. - marcan, on 10/12/2007, -0/+6@chrisxkelley
The IT Crowd is awesome :) - HotGore, on 10/12/2007, -3/+9He's a witch! Burn him!
- viperman5000, on 10/12/2007, -0/+6Pretty cool, but I learned this from watching Donald in Mathmagic Land.

I wish there was a way to digg the people down who dugg you down. - avatarpalin, on 10/12/2007, -0/+5You know what, for a moment there i thought i was going to be the first to unlock the code to finding a patter in this...
but.... then I started drinking.... and well now I am looking at porn. - fyre2012, on 10/12/2007, -0/+5agreed, it is arcane!
I found this thing very helpful. I could never grasp certain math concepts, but having a visualization like this for other 'special' math quirks really would have helped in high school. - FluffyArmada, on 10/12/2007, -0/+5not if your math teachers sucked
- TheYellowMole, on 10/12/2007, -0/+5@5th Wall: I prefer the version "e^πi+1=0", which arguably relates the five most important numbers in mathematics.
- dopplerdog, on 10/12/2007, -1/+5@Managore
Not true that Pi has no simple way of being calculated. There are plenty of ways of expanding Pi as infinite series, each more wonderful than the next. And some of these are fairly simple expansions, e.g. those found by Gregory and Leibniz. See http://mathworld.wolfram.com/PiFormulas.html - daofma, on 10/12/2007, -1/+5pie is 8.53973423
