聽演講時的心態

費瑪最後定理 書中有一段是 Nick Katz 提到關於聽演講時的兩種態度，我覺得很微妙，所以節錄於此。

我想答案是當你聽講時確實有一種緊張心理， 不知該弄懂每一件事還是讓演講者繼續講下去。 如果你不斷地插話 -- 我這兒不懂，我那兒不懂 -- 那麼演講者就無法闡明任何東西，而你也不會有所得。 另一方面，如果你從不插話，你就會有幾分迷惘， 你有禮貌地點著頭，但是你實際上沒有核對過任何東西。 提問得太多與提問得太少之間的分寸確實很難把握， 到了那些報告結束的時候 (那正是這個問題滑過去的地方)， 很明顯我犯了問得太少的錯誤。 Nick Katz, p. 252

以下是原文：

I think the answer is that there's a real tension when you are listening to a lecture between understanding everything and letting the lecturer get on with it. If you interrupt every second -- I don't understand this or I don't understand that -- then the guy never gets to explain anything and you don't get anywhere. On the other hand, if you never interrupt you just sort of get lost and you're nodding your head politely, but you are not really checking anything. There's a real tension between asking too many questions and asking too few, and obviously by the end of those lectures, which is where this problem slipped through, I had erred on the side of too few questions.
