 | This page in a nutshell: It's obvious. Right? |
A lecturer writes a statement on the board, turns to the audience, and starts: "It's obvious...." He pauses, turns back to the board, studies what he has written, scratches his head, pulls out an iPad and fiddles a bit. He then runs back to his office, where he looks through several books. Running back to the hall he resumes: "Yes, it's obvious."
