On Freethought Radio, Dan Barker and Annie Laurie Gaylor analyze the oral arguments heard this past week in the Supreme Court “Hobby Lobby” case, challenging the reproductive mandate of the Affordable Health Care Act on religious grounds, they celebrate Tom Lehrer’s birthday by listening to some of his songs, as well as Eric Idle’s “The Galaxy.” Then they speak with modern Renaissance Woman, Indre Viskontas, opera singer, scientist (Ph.D. in neuroscience), host of the Inquiring Minds podcast, co-star of “The Miracle Detective” TV series (which aired on the Oprah Winfrey Network), science/music educator, and atheist. Afterwards, infectious disease M.D. Mark Crislip plays whack-a-mole once again with the pseudoscience of acupuncture. He gives us an in-depth examination of a recent study of auricular acupuncture published in the British Medical Journal that claimed positive results. Good journal, must be a good study, right? We’ll find out. For people in our camp, the choice of what words to use to describe our beliefs, or lack of them, is a highly personal one. “Atheist,” “agnostic,” “naturalist,” and “secular humanist” and even “bright” all have their passionate advocates. (Well, maybe not “bright”.) In hour two of Skeptical Sunday, rockstar astrophysicist Neil de Grasse Tyson, host of the new Cosmos series, tells Massimo Pigliucci and Julia Galef, hosts of the Rationally Speaking podcast why he avoids the label “atheist” and an interesting conversation on labels and language ensues.
