'Near the beginning of the semester he invited all dozen or so of us accelerated students to his house for refreshments and a little "welcome to chemistry" speech, followed by a lengthy hi-fi rendition of recorded whale sounds. Judging from the perplexity on my classmates' faces, this was a brilliant pedagogical intervention, sending the message, "You are completely out of your depth." You don't know shit and you probably never will.' -Barbara Ehrenreich, Living with a Wild God
