  1. Nothing on the box at all about weight. I don't have a scale that's
    accurate enough to give even an estimate.
     
  2. they are slowly getting more common but even then the bunnings near me has
    three imperial screws for every Metric.
    I remember a couple of years back wanting a countersunk 6mm Bolt for a
    speaker could I got one locally ??? nope I ended up having to go to a
    specialist Bolt place (Mason & Amson) to get one.

    Of course I love all the metricised Measurements we still have like Ply sold
    in multiples of a foot, Sorry multiples of 300mm
    and the old 2 by 4, sorry 50 by 100mm (well actually this one almost makes
    sense)
     
  3. But the old saying "Chubby, tubby, two-by-four, couldn't get thru the
    kitchen door" won't make sense to the kids anymore..

    And then there's the definition of A LART: beat over the head with a
    clue by four. How will they understand that??

    :-O

  4. Years ago, my son (now 23) was at my mother's house and she asked him to
    dial a phone number for her. He came back holding the phone, puzzled- "how
    do you work this?"
    It was a dial telephone.

    Cheers!

  5. Yeah, same here. One of the Pacific Telephone technicians said his kids
    had never seen a rotary dial telephone(!) They didn't know how it worked.

    I repaired a strowger switch once. :)
     
  7. So did I. But it was in the Comm Room of the U.S.S. Ticonderoga, the
    aircraft carrier. That thing's a floating city!

    Do you know the difference between a lockwasher and a split washer?

    Well, a lockwasher has those little tabs around its perimeter, or
    inside, depending on if it's internal or external, and a split
    washer, that's a douche bag.

    People might or might not find this amusing - I reserve judgement, because
    when I was in about fourth grade (about age 9, I guess, about 1958-ish),
    they had somebody come in to the classroom with a big telephone mock-up.
    It had a dial almost a foot in diameter, and even had a reasonable
    simulation of the contacts in a real telephone dial - the rep showed
    us that if you don't release the dial and let it run back at its own
    pace, (it's got a governor. True!) the contact bounce will cause a misdial.

    We had classes on how to read a clock.

    We had a segment on how to write a check, and balance a checkbook.

    Any other nostalgic thoughts of the days when they actually taught
    kids stuff?

    Cheers!

  11. Years ago a friend's parents lived in a hillside house that had a finished room
    on the downslope but only accessible from outside. His mother was sewing in
    the basement room and had the doors open. She had the radio on at the time.
    The neighbor 4 or 5 year old wandered over.

    He kept looking puzzled and seemed to be searching for something as she
    continued sewing.

    She finally asked him what he was looking for.

    "Where's the picture?" he asked.

    Even then. ... perhaps 1970s??? ... Many kids didn't know what a radio was.

    We had a class in school on "Communism Theory and Practice" Where
    the seductive nature of the Enemies of civilization were shown and
    why theoretical Communism was so enticing, and completely
    unworkable. The link to a Socialists paradise and the quest for
    total control of all human life was included, with several
    hypothetical outcomes. Very impressive! Never forget the images
    of mass starvation and murder the totalitarian control might use
    ___ again!

  13. Where and when was this?

    The point is, of course, quite compelling -- if communism were a good thing,
    it would coexist with freedom, and it doesn't.

    It was in 1954, Phoenix Arizona. Several schools in my area had a
    special visiting teaching staff for this class, the entire
    presentation took 4 hours. Don't remember who put it together,
    but there was an National Guard Captain as one of the teachers.
    (Not in Uniform) There was no test but we talked about it in
    assembly a lot!

    We had the usual Civil Defense courses taught the same way! You
    know the ones, about surviving an atomic bomb attack. We only
    used the drill when a hail storm broke nearly all the windows in
    the school. Back then we had a lot of windows, to provide a lot of
    natural light! No more. The size and placement is rigidly
    controlled.... 'For Safety"

    They taught us some stuff about Communism too - one of the things I
    vividly remember is the segment on propaganda tactics. And I see
    fanatics off all sorts using the exact same tactics, and getting away
    with it.

    One little event that I also vividly remember was an item in "The
    Weekly Reader" called "The Little [hammer-and-sickle]ed Schoolhouse";
    it talked about those poor kids in the communist regime: they only
    get told what they want them to hear, their lives are planned out
    for them, they only get to take what courses they're told, everything
    the communists say is a lie, etc, etc, etc. So I asked, "So, what's
    to guarantee that they're not doing this exact same thing to us?
    How do we know that _this_ is true, and not just some propaganda,
    just like they say they're doing to the poor Russian kids?" The
    teacher got very nervous and changed the subject. Turns out it was
    during the days of Joe McCarthy and HUAC - almost as insidious as
    the current "Homeland Security" evil.

    And the Big Lie works a lot better these days because people are

    *SO* *FUCKING* *STUPID*!!!!!

    Thanks for letting me share,
    Rich

  17. ----------------------
    Sure it does, the rich have simply redefined it so you don't call it
    freedom.

    ----------------
    Yes, sure, they made you forever deeply reluctant to believe anything
    someone who said they were a communist might say to you, no matter how
    reasonable, for fear that you are somehow being duped.

    This, paradoxically is the exact tactic used by those who wish to
    control you, because it makes you doubt anyone who could rescue you
    and your credulty from their clutches. This is the method used by
    religion, and by antisexuals to convince you that you're a pervert
    and that you need to deny your sexuality at all costs lest you be
    discovered.

    This is McCarthy-ism, this is the same old witch-hunt tactic.

    --
    The only truth that can rescue you from this imposed self-doubt is
    being persuaded that what is reasonable must still be true!!
    Require that things make sense or you ARE LOST!!

    As an Englishman who goes to the US a lot one of the things I have noticed
    is the gaps in the education and the things that US children are not taught
    or told about. For example when I went to primary school (7 to 11 years) we
    were taught all the American Indian tribes, where they came from
    geographically, who was friends with whom and generally about their
    lifestyle. I haven't met a single American who was taught it at school
    which, to me, seems absurd. It seems that all americans know about the
    pilgrim fathers which in terms of the whole picture was a fairly
    insignificant event.

    This is not a dig at American education because I am sure the same applies
    to me, it's just that I can't see my gaps unless someone points them out to
    me.
     
  19. I remember knowing the names and locations of numerous tribes. This was
    standard in elementary school in Georgia in the 1960s. I didn't retain much
    of the knowledge, but it was good to know the information was available.
    That is Massachusetts chauvinism. Much of American history can be read as
    an attempt of Massachusetts to run the entire country. The Mayflower
    Pilgrims (Massachusetts, 1620) were in my opinion much less historically
    important than the first successful English settlement (Jamestown, 1607,
    commonly glossed over because it happened in the South).

    We are also taught that the Mayflower Pilgrims invented Thanksgiving, which
    sounds silly once you've encountered an English Harvest Festival. The
    Mayflower gang may have had something to do with setting the date of
    Thanksgiving in the U.S.; I'm not sure.

    To what do you base this on?

    I was taught all of that stuff in depth when I was in grade school, some
    40 years ago. My son is currently in elementary school, and that is
    what they are doing right now.
