Eg., yesterday, a friend who's used his exotic 220 volt welder at many industrial sites was pulling his hair out trying to wire it up in his house. Various electricians have shown him over the years how to connect the different wire colours in other settings. His basic problem is that nobody taught him an abstract model for basic wiring circuits. Once he gets it working, assuming his house is unburnt, the connections will have no intrinsic understanding of the theory used to make them. But the circuit model is the mental view he must have in order to see that he must connect connect a white wire to a "red" or "black" prong instead of to a "white" prong. Without that, he might as switch to xml programming. Received on Wed Dec 03 2008 - 15:48:46 CET
