Gary asked: >how do we make electric lights work etc.? Flip the switch up. Unless it is a light controlled by two switches then flip it in the other direction. In Bill Gate' new home you simply walk into a dark room and the lights turn on automatically. Ten years ago I worked with an Electrical Engineer that was paralyzed from his waist down. Karl Hansen used a wheel chair and had hooks on his arm that could barely hold a pencil or peck at a keyboard one key at a time. So Boeing had motion sensors installed in his office, Karl was one of the very few engineers at Boeing with a private office, so if anyone(including Karl) entered or moved in the room the lights were on. Karl knew how his lights worked but he did not have to. Just trying to be cute Gary. I know what you mean but the fact is in the information age we can either know more about how things work http://www.howstuffworks.com/ or less: http://www.imx.nl/photosite/comments/comment1098.html <snip>The loss of reality. That result is increasingly an 'image' and not a 'picture'. Imaging is part of the advertising world and the graphic arts world. An image can be a drawing or it can be a persons perceived identity. A supermodel is an image, an illusion as is an illustration. Culturally the disappearance of the word 'picture' means a detachment from reality. War photography showed a grim reality and we knew it to be true. The recording instrument (the Leica-camera as example) and the film used (Kodak Tri-X as example) guaranteed by their technology a true image of the world in front of the cameraman. Now we have images of war-scenes. Digitally recorded, digitally transmitted and digitally enhanced or manipulated. The source image is the flash card or the hard disc. Once erased we have no chance to go back to the source . Of course I know that pictures could and have been manipulated. But is an exception and not part of the technique. Now it is inherent in the techniques used. <snip> There is so much wealth, free time, safety-nets(insurance, social security, etc.), that most people most of the time can just kinda kick back, lift a cool one( and other drugs), veg out in front of the entertainment center(Stereo, TV, Feelies,…) and expect a doctor to repair the damage to their bad hearts and hurting knees when they eat too much of the wrong sort of foods and do not get enough exercise to their bodies and minds. We can, if we want to, leave the dealing with reality to the experts and professionals. So Logo fanatics? Which is it? Does constructivist philosophy or "Piagetian learning" or whatever you want to call it, encourage you to lead a life based on the truth determined via your own senses and experiences integrated and analyzed and remembered with your individual mind in your lifelong search for reality(reference the last few pages of Brave New World)? Do you tell your students they must hurt(suffer reality) here on earth to earn a place in heaven? Or is there other/better reasons for learning about how things work? That the purpose of Logo is to better understand the real world or to escape from the real world for a couple hours? Kinda getting into religion aren't we? That is why libertarians want to Separate School and State.
