Barbie makes it to computer class just before the bell rings. As soon as class begins, Barbie raises her hand. "Yes, Barbie?" asks Dr. Smith, the professor. "I tried to automatically prove the Riemann hypothesis last night," says Barbie, "but my tool couldn't do it. I was thinking maybe research just isn't for me?" Dr. Smith laughed. "Barbie, you're doing just great. Why don't you start with a theorem for which there already exists a paper proof?"
