Pi you say?

I just did a comic talking about pi and it makes me wonder, how many digits of pi do you guys know? This is how far I know pi (as stated in the comic blurb): 3.14159265358979323. At one point in time, I knew more digits of pi, but eventually parts of my social security number started working their way in and replacing the once correct digits.  That’s when I abandoned those extra digits. This may not be the coolest topic, but who cares! It’s pi! Pi is cool!

    I was actually surprised to find that I know exactly the same number of digits. I used to know two more but I could never remember if it was 62 or 26 or something completely different.

    • josh(new 2 this webs says:

      It was probobly 62 beacuase i tried and ended up with 62 as an extra numba!

      PS:sorry about my dumb spelling!

      PSS:have u ever seen the dumb dinosaur clip on funnygames.biz? its soooo funny! bye!

    Here's by far one of the best PI sites I've ever seen … not only do they go really long but there's a song!

    I know all of them.

  4. Alex says:

    I got to the big 100 :D

    It started off as a challenge between me and my friend. I got to 50. Then we got more and more until I got to 100, I think he got to about 110 or so.

    Quite sadly, I am not making this up. And just in case you're wondering, yes, I do happen to have a very beautiful girlfriend.

    For anyone who wants to know…

    well i only know my sweet apple pie bake at 180C

  7. geoffrey says:

    Ahh I have this awesome shirt with hundreds of digits of Pi over the symbol. You pick it up when people start reading it to you every other minute: 3.1415926535897932.

    and now '3".

  8. retsoksirhc says:

    I go almost as far. 3.14159265358979

    I'm probably going to be in a race next month, and I'm planning on being number pi.

    • retsoksirhc says:

      Oh, and I almost forgot. Some nerdy guy I used to work with taught me this.

      Pi = 4 ( 1/3 + 1/5 – 1/7 + 1/9 – 1/11 + 1/13…)

      I, however, prefer to find the perimeter of an n sided polygon while n approaches infinity.

      • josh(new 2 this webs says:

        U R VERY CONFUSING!!!!!! the n shape of a polygon=???? blah blah blah!!! man i h8 my life im gonna go kill myself!

      • Che Guevara says:

        hahahahaha

        go that is soo funny to a mathematical student…..

      • hirschmj says:

        Um, no it isn’t. The formula as you wrote it is 3.820535, and it only gets worse as you continue.

        • Mr. Saturn says:

          You all fail. Pi is obviously pie divided by ~2.718281828459045. More exactly: pi = pie/lim[n–>infinity](1 + 1/n)^n

  9. Uh...I have no name. says:

    Pi = 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 (edit: truncated due to ridiculous length)

  10. zoë says:

    Smart people reading and writing here…

    i go as far as 3.14

  11. Fiona says:

    I know a guy who claims to know up to 50000 digits (he's probably lying). Personally, I prefer the pastry to the number.

  12. Patrick says:

    My Nintendo Wii is named Pii. And although there is an extra "I," I find this relevant because it is still just an obtuse of a word as pi. I only remember 3.1415926535 because my address is 535 and I would always get excited about and distracted by that.

    • Pedro says:

      how do you pronounce your wii's name then? I cant imagine it would rhyme with nintendo's name for it…

  13. Alex says:

    I swear on all that is holy that I actually memorized about 240-250 digits of Pi. We were having this contest at my school; whoever memorized the most digits of Pi got a $20 gift certificate to Chapters. Needless to say, I won by a long shot. True story!

    i win

  15. MennoW says:

    hahaha i only know 3.1415 :')

    but i did found this:

    Theorem: All numbers are equal.

    Proof: Choose arbitrary a and b, and let t = a + b. Then

    a + b = t

    (a + b)(a – b) = t(a – b)

    a^2 – b^2 = ta – tb

    a^2 – ta = b^2 – tb

    a^2 – ta + (t^2)/4 = b^2 – tb + (t^2)/4

    (a – t/2)^2 = (b – t/2)^2

    a – t/2 = b – t/2

    a = b

    So all numbers are the same, and math is pointless.

    which i found very funny :P using math to prove math is useless

    • Che Guevara says:

      thats great…. im putting that on the start of my math hsc test! (then proceeding to finish the test)

    • retsoksirhc says:

      Hmm.

      4+6=10, so far so good

      (4+6)(4-6)=10(4-6), -20=-20, still good

      4^2 – 6^2 = 4(10)-6(10), again yes -20=-20

      4^2-10(4)=6^2-10(6), and -24=-24

      4^2-10(4)+(10^2)/4=6^2-10(6)+(10^2)/4, 1=1. Yep.

      (4-10/2)^2=(6-10/2)^2, 1=1 again. Yeah.

      Now for the mistaken step. 4-10/2=6-10/2. The squares of these are equal, but not the roots. sqrt(y^2) can actually be (y) or (-y).

    • JW says:

      > a^2 – ta + (t^2)/4 = b^2 – tb + (t^2)/4

      > (a – t/2)^2 = (b – t/2)^2

      This is completely incorrect.

    • Erik says:

      amazing.

      girls=time*money

      time= money

      girls= money*money or (money)^2

      and because money is the root of all evil

      money= {square root of evil}

      therefore:

      girls= {square root of evil}^2

      so: Girls=evil

      math cant lie people.

      math cant lie.

        rolf totaly also

        video games = fun

        video games^2 = nerds

        video games^3 = fat loser in there moms basement

        video games^4 = death

    That's all.

  17. Sian says:

    … isn’t there a 3 in pi? that’s about as much as i kno… well not really
    it’s like… 3.14159 (and i got that off of a song on an exemplar problem… it’s kinda lame :P)

  18. MennoW says:

    retsoksirhc

    damn you, you won =( now i have to fiend something else to not do my math ;)
    smart… =)

    LOL@ drew’s new cartoon, hahahahah

  19. Amber says:

    I know this girl who can recite something like, the first 300 digits– it’s ridiculous. She rattles them off so fast I can barely process them, let alone remember them! As for me, I only know 3.1415926.

  20. Che Guevara says:

    hahahaha pi out of 5 what would ever posses you to do that?

  21. dietJESUS says:

    Ha, I epic fail at math

    I know….

    3.14159?

    is that right?

    let's just say 3.14.

  22. Bernard says:

    pi to ONE MILLION PLACES.

    I think Bernard wins.

  23. Graham says:

    At my school, we have pi day on 3/14 (March 14), and a small competition, usually for extra pie…

    I knew 254 on 3/14/07. I’m back down to a very-memorized 116, but I will start training for 500+ now >:D

    (It did take extra effort)

    • Patrick says:

      Wow. We had Pi day too. It was especially nice for the Math Team because sometimes Math Man would bring us pie.

      …I'm so awesome.

  24. mai says:

    My school's math honor society (which I'm in XD) is having a competition on Pi day to see who can recite the most digits of Pi. I think the prize is a TI calculator.

  25. Che Guevara says:

    whats a TI calculator?

    • Mai says:

      TI = Texas Instruments.

      As in a graphing calculator.

      have you heard of the TI Inspire? It does algebra! It's only $80 I think, but my dad won't buy it for me. I think I'll buy it for myself before I take calculus next year.

  26. Sean says:

    Actually my freshman year of college, I had about 3 hours inbetween 2 of my classes a few days a week. Needless to say I got a little bored, and decided to learn Pi. It was originally just to see how far I could take it. I ended up getting up to around 160, fairly fluently. Now I'm only about 80 digits, but hey that ain't bad.

  27. RocketSci says:

    I think you meant

    4*(1-1/3+1/5-1/7+1/9…)

    You forgot the leading 1 and you flipped the sign on the 1/3 term.

  28. Che Guevara says:

    And I refer to the link i previously posted out of common sense as to not clog the server!
