    what does it mean that

    5 divided by 2 = 2.5 and
    6 divided by 2 = 3 and
    both square umm.. stems end with the number you're multiplying by itself.

    posTMOd whispered in my ear that it means Jesus is coming.

    But he's probably just joking, that rat-bastard.

    Keith? Sunny? Beaker?

    Any answers?

    nothing much.
    just a quirk of those particular sets you've chosen.

    for example, try 4x4, 7x7...

    no - always wanted to though.

    You have discovered the secret of the universe.

    Be careful not to tell anyone.

    (haven't you seen the radiohead video?)

    I have one too:


    How can you take stuff, and make it into nothing? Some sort of magic I suppose....

    Actually, something I do find interesting is that any number with an infinite series of nines anywhere past the decimal place is... ah, lemme show you:

    1.343567999999999999... = 1.34568

    1.999999999999999... = 2

    Prove it.

    1/9 = .11111111111111111111111111...
    2/9 = .22222222222222222222222222...
    3/9 = .33333333333333333333333333...
    4/9 = .44444444444444444444444444...
    5/9 = .55555555555555555555555555...
    6/9 = .66666666666666666666666666...
    7/9 = .77777777777777777777777777...
    8/9 = .88888888888888888888888888...
    9/9 = .99999999999999999999999999...

    what an insane and crazy world

    exp(pi*i) = -1... << know as the unifying equation because it eloquently links geometry, algebra, and complex analysis.. it is also interesting because it is the backbone in some ways of wave theory mathematics... weeeiirrd (i = squareroot of -1 a number which exists only in theory in case you dont know)

    but even more f******* is Picard's Theorem:

    "in each neighborhood (area surounding a critical point) of an essential singular point (a position at which a contour becomes infinite in an irriversable fashion), a function assumes every finite value, with one possible exception, an infinite number of times"

    so, lets say our contour is a gravitational field, our essential singular point is some kind of black hole or some other fuck'd up shit, then the gravitational intensity of each around that position will assume every known value in existance except for ONE.. (ooohhh).. even more interesting is the fact that that value will be unique to the design of the singularity..

    its like identification numbers for black holes

    I'm sorry, but last time I checked, I though 9/9 = 1

    Kinda like 4/4 = 1, 3/3 = 1

    yes, but .99999999999... is a 'convention' only.
    its just an axiom.

    like in euclidean geometry, "two parallel lines never intersect" (or they intersect only at infinite distance away)
    you can't prove it; its a definition.

    i could likewise simply define *&#%& = 2 and that'd be fine.

    say... that makes a lot of sense. because, some day, someone might want to pull stuff out of a black hole, so they have to have an id for each one so they know where to go.

    pffft.....I could prove it.... if I had enough tortoises.

    Were you paying attention? 0.9999999.... = 1

  24. PosTMOd

    Look at it this way:

    1/9 = 0.11111111111111....

    8/9= 0.888888888888888...

    1/9 + 8/9 = 9/9

    OR 0.11111111.... + 0.88888888.... = 0.9999999999....

    hardly - it's also better known as i in the mathie circles and j in engineering circles (specifically electrical). it's extensively used in electromagnetics and controls to accurately model systems. without them there wouldn't be a hell of a lot of technology as we know it today.

    i personally prefer my complex numbers in polar form.
