a few days ago i screwed up my laptop and have had to go to the desktop to write here.  It messed up my spontaneity bad, but I’m getting used to it.  So I have been preparing a lecture about wisdom I will have to give with Mayzun in a few weeks about academic wisdom, and when I complained to Ezi that I had no good example to give of the need for general knowledge and wide vision, he reminded me of the story of Professor Hanan Harari who claimed to have done a survey of prospective students for engineering and asked them “If you had to construct a conduit for blood from ashdod to Eilat what would you have to consider?”    There were many great mechanical answers but no one asked why.
