    I know what a dipole is but it says i have to use dipole approximation to calculate potential for a point in a electric field caused by a dipole, so what's a dipole approximation?

    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13

    oh my, he doesn't even know what dipole approximation
    is.

    Yeah, well I'm gonna build my own lunar space lander! With blackjack aaaaannd Hookers! Actually, forget the space lander, and the blackjack. Ahhhh forget the whole thing!

    something more complicated than that, i need a lot more variables and stuff into it!!! I mean i know the Electric Charges the positions of them and the position where i need to calculate the potential, that's way too simplified equations at that link

    ok then.

    taking into account that the electricity is supplied by two small hampster in a wheel connected to a dynamo. and also taking into account that these hampster's are feeling rather hungry and that there is a piece of lettuce dangling in front of them, I would say the answer to you question is 42.

    42 makes sense

    yeah that sounds reasonable, since 7*6=42

    that's not quite how i got the awnser I got it by

    h*((a*b)/c)+d)) = 42

    where

    a = 7
    b = 6
    c = 2
    d = 21
    and h is how hungry the hamsters are feeling.

    Sorry mate, I won't ruin your thread any more, just a little fun. I did do this all at school many a year ago, but that was many beers ago.

    42: possily a little bit too "Hitchhiker's Guide" for such a sensible thread.
