The mainstream rap and hip hop communities are known not only for a way with words and penchant for controversy, but also for occasional drama. Rapper Greydon Square is no exception.  On this week's episode of Skepticality, Derek and Swoopy hang loose with Greydon and talk about his musical influences, being embraced by the atheist community — and why this Compton native (raised as a legal orphan by the Department of Children & Family Services of California) refuses to be a product of the system.

Continuing from last week's interviews recorded at the "Amazing Meeting 6" conference, Derek & Swoopy talk with secular lobbyist Lori Lipman Brown and her father Mel Lipman (both secular humanists with backgrounds in law and government).  They also speak with mentalist Banachek, who has been responsible for putting more magic and mentalism on American television than any other magic consultant in the world. While the paths of these skeptics seem widely divergent, Derek & Swoopy learn that their common decision to further skepticism within their chosen professions illuminates many similar truths…

This week on Skepticality, Derek and Swoopy return from the desert with highlights from "The Amazing Meeting 6" conference in Las Vegas (hosted by the James Randi Educational Foundation). Joining them are two skeptics who are changing the face of popular science: astrophysicist Dr. Neil deGrasse Tyson, and MythBuster Adam Savage.   The incomparable Neil deGrasse Tyson (Director of the Hayden Planetarium at the American Museum of Natural History, current host of Nova Science Now, and the only astrophysicist to be named one of People magazine's "Sexiest Men Alive") talks with Swoopy about getting the United States back on track as science innovators. (He also sets the record straight about Pluto.) and in his third appearance on Skepticality, Adam discusses his evolution from artist and model maker to skeptic and television scientist—as well as thoughts about his life after MythBusters.
