Read’em & weep… or laugh? You know, according to your mood today.

Thanks Rick, Greg & Kat.

Quote of the Day:

“You have got the power to deflect [an asteroid] , you now have the power to not greet the same fate that the dinosaurs did 65 million years ago when an asteroid came and took them out leaving them extinct. Because I don’t want to be the laughing stock of the galaxy when they find out that a species that had a space program and the intelligence to stop an asteroid impact just simply went extinct. That’d just be embarrassing.”

Neil deGrasse Tyson

  1. Blackboards and chalk…..
    You know,

    We went to the moon using slide rules, blackboards, chalk, pencils and paper. The Apollo space craft used a computer on board that wasn’t much more powerful than the one in my microwave oven. The advantage of a blackboard is that it makes you think things through as you write them out, because it is a bit slower than typing. Plus, it forces you to stand in front of the class and, supposedly, your peers while you do it. The mind is the best computer, after all, and working things out in this manner can, at times, be a better method than computer modeling.

    It’s not the tools that you use that are important. It is the ability to use them that counts. It is the ability to understand the capabilities of your tools, and the medium you intend to work with, that trumps the tool itself. It’s like we say when teaching marksmanship: “The most important part of the weapon is the nut behind the butt plate.”

    1. Well…
      I was gonna disagree with you… but then I realized you have the skills to shoot me from a distance of 500 yards or larger, so I’ll refrain! 😉

      No, I know what you mean. It’s interesting the way we shape our tools and the way WE are shaped by them. Google and the Internet has for example changed the way I read and absorb information, and you tend to see that more among the younger generations who grew up with this technology and don’t know a world without it.

      Having said that, any self-respected music lover knows that it’s not wise to give your back to ALL ‘analog’ technology. Likewise, there are certain things we should preserve about the old teaching methods. Changing a chalk blackboard for an interactive electronic whiteboard IMO still preserves the best of the teaching technique of portraying abstract ideas into intelligible symbols.

      Of course, nothing is free and for every gain there’s a loss. Perhaps with the disappearance of the grand lecture format, students will tend to have less respect (or fear?) toward their teachers, or something different. But maybe the same thing happened with the introduction of the blackboard 2 or 3 centuries ago, when classes were completely oral and you had to pay attention to what the teacher was saying 100% of the time.

      1. Agreed..
        Especially the part about shaping our tools the way WE are shaped by them…

        I do a lot of model making and have found that dental tools make excellent sculpting tools. However, on occasion, I’ve been forced to modify some of them to do just what I want. Because i am a strong believer in recycling, I also never throw away anything that might be valuable, and make tools to do things from recycled materials. Sometimes even whole models, or significant parts are made from them. But I digress…

        There is also the fact that sometimes you can’t really improve on certain tools, more than in a cosmetic way. For example, if you were to unroll a 1st century Roman surgeons instrument set alongside a modern surgical set, you’d be astonished at how alike they remain. The only significant change (for some instruments) was post-1870, when Lister’s work was incorporated and sterilization of instruments became mandatory. Many instruments had wood or bone handles, and these had to be replaced by all-metal in order to withstand the heat of the autoclave, as well as keep infectious agents from becoming trapped in crevices and openings. Otherwsie, however, a tenaculum is a tenaculum, and a bistoury a bistoury, regardless of the era.

        1. Oh yeah!
          As an Industrial Designer, I’m only too aware of the futility of trying to improve a time-tested design.

          You would only have a major re-design in things like chairs or hammers, the moment that we either a)move everything with our minds, or b)do a serious modification to our bodies.
