Season 2, Episode 4

In this episode, we look at the tension between ?slow food? ? a return to the past ? and the food future. You?ll hear from slow-food champion Alice Waters and uber-modernist Nathan Myhrvold, who advocates bringing more science into the kitchen ? including, perhaps, a centrifuge, a pharmaceutical freeze drier and ? a food printer?

Also in this episode: we delve into the social mores of Twitter. Is it a two-way street? Do you have to follow someone on Twitter to garner a large following yourself? Or are the mores of a digital friendship different from those in real life? Hear about the Twitter give-and-take from sociologist Duncan Watts. Also, Justin Halpern parleyed his hit Twitter feed ?Shit My Dad Says? into a best-selling book and a TV show; we learn about the one guy he follows. And Steve Levitt weighs in on just how important (or not) Twitter is in his life.
