Barack Obama's candidacy has raised a host of issues surrounding race in America. To help address some of those issues we have Dr. Camille Charles on the show this week. Camille is the Director of the Center for Africana Studies at the University of Pennsylvania. She'll talk with us about how race has played a role this political season.

While Dr. Charles is studying the language we use around race, Lindsay Zaltman has written a book about the language we use to describe what we buy. He's the co-author of the book about the use of language and how a powerful metaphor can be used to change perceptions: perceptions of a candidate or a city.

Plus our producer Scotty Iseri brings us a conversation with the creator of the books Hack. Dmitry Samarov is an artist whose day job provides him with unique inspiration for his art.
