    i don't see why it's so special - to make the next A size up, you just stick two of the previous sizes together, along the long edges. Thus the ratio is maintained (im only doing A-level maths - it doesn't take a genius). That the ratio is so simple is a little interesting.

    little trivia: A10 is the smallest size (26 x 37 mm) - what on earth would you use that for??

    it's bloody difficult to convey irony and sarcasm on text. i was trying to be a little mocking to the thread, but failed pretty badly. subtlety is perhaps not my strong point...

    lol, i'm think i'm beggining to like you crazy, not to sure about silence though, lol, paint it on ya frton garden, means basically be in your face with it, bombard you with it, which was tru (fair do's silence)

    aston's a good place, if i was gonna stay in brum for uni, i would prob wanna go aston, but brum is a LOT different to "tiny boring village called Llangynin" as we have people and shops and electricity, lol, just joking, but seriously, dont be scared by a major culture shock, a mate of mine came from Brecon to brum for uni last year, and she was like woh!, the one thing she said which shocked her, was that at night the amount of rats in town, which i spose, us brummies get used to now, and few rats in town in the mid of the square, but she was scared. but you'll be fine

    right.

    today i actually witnessed the sheer wonder of this phenomenon. by folding a piece of A4 paper in a certain way (so that the longer side of 297mm is folded back to have one end of the length as the origin for the folding point, and the other end touching the parallel opposite length). an isosceles triangle is then formed, resultantly being one half of a square (which would be 210x210mm), with the base being √2 in arbitrary units, relative to the sides having a length of 1.

    isn't this cool

    the ratio of side lengths for standard paper (i.e. A4, A5... A3.. A1..) is 1:√2

    i.e. 210:297mm for A4 :cool:
    is it the divine ratio? 1.618 etc?
