>What’s striking is that the professor and A/Chairman doesn’t know that he doesn’t know. I’m struck by his ignorance of his ignorance, his willingness to think that he knows what he’s talking about when he doesn’t.

Does this make sense to anybody? The author is "struck" that somebody is "willing" to talk about something they believe they understand? The only annoying thing about academia is that it seems to attract smug, selfish people like this.
