  1. Unless I'm mistaken...

    There are standard envelope sizes used for
    postage. And these vary between the US and
    "rest of world." Envelope size in turn dictates
    the size of the enclosed paper. [I may have
    causality backwards, but the effect is the same.]

    Anyway, if one is preparing a mass mailing (say,
    tens or hundreds of thousands of letters) then
    one might do well to consult the postal rates
    and regulations when choosing the size of
    the original.

    Not because of the polizei but to save serious $$.

    I remember when I was young there was a
    standard "Par Avion" form that one could buy
    at the post office for international air mail. It was
    a super-lightweight blue-tinted sheet that formed
    its own envelope.

    You'd take it home, write or type your letter
    onto it, fold it up and drop in the mailbox.

    You mean like this one ?


    Gag !!! But I have to admit I really like some SUV's for their
    incredibly bad aerodynamics. You see I ride a motorcycle and drafting
    a RAV4 is easy. You just have to be within 100 feet of the rear door.
    I mean there is almost no way that thing could ever spin out of
    control given the drag on the rear end ! And my fuel economy increases
    about 10mpg when I'm behind one.

    years ago when some old-age issues came up.

    Here's to you!

    That gives me a chuckle.
    Everybody I know has always called it "math paper",
    because that was the size of the buff-coloured sheets of paper
    we were given in grade school on which to do math problems.

    Nope. It's the engineers and machinists that are slowing down the
    I don't see any basis for saying that the US system of measures is
    "loosely a base 8" system, any more than it's a base 4 system or base 16

    I can only agree that measures based on things like the size of kernel
    of corn
    (however one happens to define corn), the width of somebody's finger, etc
    is pretty arbitrary.

    OTOH, the distance from the equator to the pole seems like a pretty
    way to define a meter. (or is that "urban" legend?)

    Anyway, while counting and dividing and multiplying things by 10 seems
    (unless, of course, you happen to be one of those people with a
    different number
    of "fingers" (in which definition we arbitrarily include thumbs, for
    some reason)),
    I would think that multiplying and dividing and ... yes ... counting by
    2 is natural, too.
    Most people I know are reasonably adept at cutting a piece of paper (or
    wood) in half.
    I don't know many people, though, who are very successful
    at cutting a piece of paper (or wood) into 5 equal parts.

    While we're at it, what's with this thing with 60 seconds per minute,
    60 minutes per hour, and 24 hours o'clock?
    Why not divide the day into 10 hours of 10 minutes apiece, each 10
    seconds long, etc?
    Oh, but then again, that's pretty arbitrary too ...
    Maybe we should divide the *year* into a hundred (or maybe 1000?) equal
    Oh, except our planet doesn't turn around 100 or 1000 times
    in the time it takes it to go around our star --
    oh, dear, how *arbitrary* of the them not to behave in a metric fashion.

    This started out as a question about the size of paper used by photo labs
    in different parts of the world, or something like that, did it not? <o_O>

    QUICK: What's the next standard drill size down from 13/64" ?

    The next one down the line in my box of drill bits.

    The nice thing about killometer is that it sounds so much grawnder than
    having four times as many syllables and all.
    Now if the EU's (or is that ewes) could just come up with a
    *ten*-syllable word
    that meant the same thing, that would be even better.

    In the meantime, we can condole ourselves with the fact
    that it's so much easier to write poetry in the metric system --
    all the sizes and distances end in meter and rhyme with Peter,
    and all the weights end in gram and rhyme with d--n.

    However, the picture (remember pictures, and photography, and stuff?)
    of automobiles wearing metric bathing suits boggles my mind.

    Get used to it. Actually, don't.
    Eventually, all those English (well, Amurricane) units will disappear
    from your equipment,
    to be replaced by everything written in *six* languages,
    as they do in the civilized parts of the world.

    Hurrah! On that last point, I'm with you.

    (I considered posting that metric seems to me to be more natural
    (what with 10 "fingers" (well, digits) on the "average" human being),
    but not as precise.
    A 10.375mm, or even a 10.5mm, or even a 10.1mm, socket wrench is a rare

    Do you mean the next actual drill bit, or the next empty hole where there's
    _supposed_ to be a drill bit?! (Where the hell is that 3/16" bit?!)

    BTW, in a 1/64" bit set (which I assume because the question asks the next
    size expressed as X/64"), the next size down from 13/64" would be 12/64".
    However, we do the math, and find that 12/64" equals 6/32" which equals

    Now where the hell is that chuck key?!

    Funny, but when manufacturers here were told they had to have
    directions/content lists in two languages, one English, they chose French.
    There is a political message there.
    j, Nov 5, 2006
  14. Since you did not specify where "here" is, I'll assume that you were
    speaking about the U.S. The reason for choosing French as a second language
    is that a large portion of the Canadian population speaks French. Most
    of them speak English too, but they would be more inclined to buy
    something with French on it too.

    Based on my perception of the current politcal climate in the U.S., far
    more inclined than your average U.S. shopper would be if it were English
    and Spanish.

    You could also note that French was the language of international commerce
    for several hundered years.

    Nope. That's not the case. It is political. When told that they had to have
    a second language, they chose something other than Spanish/Mexican. It's a
    Big Deal here, this second language political thing.

    FWIW, the largest part of family is Canuck; they all speak English. No need
    for French with commerce. (My greatest grandfather was on Champlain's ship,

  17. You mean the ones that got Intel back into a competitive stance
    with AMD? Yup, it's impressive what the Intel Israel team did,
    and I saw it coming with the previous Pentium M designs from
    which Core and Core 2 sprang. Without Core 2, it was a one-horse
    race among x64 CPUs; now, 1- and 2-socket systems have real
    competition again, which is healthy for everyone.

    Larger systems, anything over 2 sockets, are still dominated
    by a single option, though, and it'll be a while before Intel
    can effectively play there.

    Er, no, where bit is supposed to be. Some people put there bits back in
    the organizer.
    OTOH, there are plenty of people who don't need organizers,
    and would just say "Oh, the next size smaller? It's under the red rag,
    next to the 11/16" box-open-end wrench."
    Well, *some* of us do the math. I'm one of those that has to,
    because I don't use those tools often enough these days.
    But when I did (when I worked on my own car (an original Beetle)),
    I just *knew* what wrench was smaller or larger and would fit.
    Interestingly, my relatively small collection of "English" wrenches
    would fit
    not only the "English" (well, they *were* English, then) nuts and bolts
    but the metric ones as well -- but very few of the metric wrenches
    were good for anything but the exact size they were.

    On it's tether to the drill cord! :)

    Well, that's one way to do it.
    Or have a complete set and just be awake when using it.
    It's not rocket science.
    It requires a miniscule portion of my brain to keep track of these things.
    If I *need* to figure it out, say for a pop quiz, I can figure it out,
    because I learned how to multiply and divide by two in 3rd and 4th grade,
    and learned how to add and subtract in 1st and 2nd grade.

    Why were mfrs told to use English at all?
    And why only two languages, when there are so many others?
    And what was the political message in choosing French over, say, Italian
    or German?
