Oh, and I suppose I should make my contribution to this thread not entirely off-topic, so let me add another +1 for Alex.
]]>On top of that, being okay feeling liking an idiot is one of the most important skills to develop.
Couldn't agree more! I do my level best to ensure that my students get every opportunity to learn this.
(I suspect that I ought to qualify that to ensure that it's not taken the wrong way, but I'm not sure whether to say that it's the students who feel like idiots or me who feels like an idiot - I suspect that I'll get keelhauled for Encouraging Bad Teaching Again either way.)
Whatever, I'm adding my support to the "don't delete old questions just because you don't like 'em anymore" party.
]]>Besides, as Doron Zeilberger is wont to say: "there are no trivial mathematical questions, only trivial mathematicians." So don't be ashamed at the questions you asked: if you feel more enlightened now then you were before, you should be happy that you've grown mathematically.
