How did you know which one was mine? I thought it was anonymous.

You're the only one with Star Trek notebook paper.

I'm Greta Johnson. I'm Tricia Bobita.

And from W.B.E.E.Z in Chicago, this is Nerdette.

This week, Stephen Dubner, host of Freakonomics Radio and co-author of the Freakonomics books. The newest book by the duo, Think Like a Freak, just came out. Dubner tells us about how he and University of Chicago economist Steve Levitt made Freakonomics, which kind of sounds a lot like our origin story, too, Tricia. Wait, what? He's brilliant and fun to work with, and I'm of average intelligence and relatively fun to work with.

We'll also get to know a great lady nerd of history, astronaut Sally Ride. Then some news freaks and geeks can rejoice over right here on Nerdette.

In a few minutes, we'll talk with Stephen Dubner, host of Freakonomics Radio and co-author of the books that made economics cool.

But first, let's get to know Great Lady Nerd of History, Sally Ride.

31 years ago, she became the first American woman to go to space.

We have to say, first American woman, because two Russian ladies went into space about 20 years before Sally did.

Seven, six, we go for main engine start.

We have main engine start.

And ignition.
