hi! I was curious as to what the "Gordian knot principle" meant, so here is the info! "Untying the Gordian Knot One day, according to ancient Greek legend, a poor peasant called Gordius arrived with his wife in a public square of Phrygia in an ox cart. As chance would have it, so the legend continues, an oracle had previously informed the populace that their future king would come into town riding in a wagon. Seeing Gordius, therefore, the people made him king. In gratitude, Gordius dedicated his ox cart to Zeus, tying it up with a highly intricate knot - - the Gordian knot. Another oracle -- or maybe the same one, the legend is not specific, but oracles are plentiful in Greek mythology -- foretold that the person who untied the knot would rule all of Asia." http://www.maa.org/devlin/devlin_9_01.html there is quite a bit more about it if you would like to go to the URL to read it. What's really funny about this is that I am very good at untying difficult knots! weird! thanks! Jules
