Southwestern University President Edward B. Burger likes to think. He likes to get students thinking. And he likes puzzles. Hence, his new course: “Effective Thinking and Creative Puzzle-Solving.” He calls it the “Seinfeld” of classes because the course “was about nothing,” as he put it during an interview.
As part of the class, students were given three puzzles a week. I asked for an example.
“I really shouldn’t,” Burger said. “They had to sign a confidentiality agreement so I could use them next year. I don’t want all the answers out. I’ll give you one. It’s the first easy one they got. It’s called ‘Who’s Who:’
“One afternoon on a college campus over a hundred miles from Georgetown, two students — a math major and a philosophy major — were talking. ‘I am a math major,’ said the one with black hair. ‘I am a philosophy major,’ said the one with red hair. Given that at least one of these students is lying, what color hair does the math major have?”
