David Kwong writes crossword puzzles for the New York Times. And he's a magician. Sounds like my kind of guy. He spoke at TED about why we like puzzles. Remember, we are all natural scientists. We want to figure out what's going on. We want to solve puzzles. And we all want to know how the magician did that amazing trick. Kwong performs such a feat on the stage that leaves you wondering about how he could possibly pull it off.
