Experts All Every adult is an expert. Shown here (clockwise from top left): a Borek (a Turkish delicacy) baker at the market, a connoisseur evaluating the bouquet of a costly red wine, a musician playing the didgeridoo, and a professor in her biology lab. Most of us would be inept and bewildered in those roles. Students likely also know a great deal about some things that are unfamiliar to others—electronic music, artistic makeup, Italian cuisine, professional baseball, and more.
