Point of Inquiry
Neil deGrasse Tyson: Space Chronicles — This week, Point of Inquiry is thrilled to welcome back one of our most popular guests: Neil deGrasse Tyson, the famed astrophysicist and Frederick P. Rose Director of the Hayden Planetarium in New York City. Last time we had him on, Dr. Tyson engaged in a wide ranging discussion about science communication and the place of science in America. This time, we focus in on his new book—Space Chronicles: Facing the Ultimate Frontier—and his call for revitalizing NASA and letting it play a central role in reconnecting America and science. Neil deGrasse Tyson is America’s most pre-eminent science communicator. In addition to his work at the Hayden Planetarium and his books and television appearances, he is also the host of Star Talk Radio.

Stuff You Should Know
How SETI Works — SETI stands for ‘search for extraterrestrial intelligence,’ and the term is used to describe both the SETI institute and the search for alien life in general. In this spaced-out episode, Josh and Chuck explore the origin, aims and challenges facing SETI.

Lawrence Krauss: A Universe from Nothing — Host: Chris Mooney We had Lawrence Krauss on Point of Inquiry less than a year ago, to discuss his recent book on the scientific works of Richard Feynman. But in order to keep up with him, we had to have him on again. Already. You see, Krauss has a new book out that’s causing quite a stir right now—A Universe from Nothing: Why There is Something Rather than Nothing. Here’s a hint as to why: Krauss’s answer to this age-old question isn’t God. In fact, as discussed on the program, Krauss has arguably written the book that "kicks God out of physics." And along the way, he also manages to explain a heck of a lot of science. Lawrence Krauss is an the internationally known theoretical physicist and popular author. He has published hundreds of scientific papers, as well as acclaimed books like the bestselling The Physics of Star Trek and Fear of Physics. He’s director of the Origins Project at Arizona State University.

Brian Greene: The Fabric of the Universe — Host: Chris Mooney It’s the beginning of a new year here at Point of Inquiry, and we’ve got a pretty good guest to kick it off. He needs no introduction. He’s Brian Greene—celebrity physicist, bestselling author, television star and all around science communication maestro. Officially: Greene is co-founder and director of Columbia University’s Institute for Strings, Cosmology, and Astroparticle Physics, author of the bestselling books The Elegant Universe and The Fabric of the Cosmos, and co-founder of the World Science Festival. We caught up with Greene to discuss the recently aired four part NOVA special based on The Fabric of the Cosmos, as well as, well, sciency things in general.

Big Picture Science
Cosmos: It’s Bog, It’s Weird — It’s all about you. And you, and you, and you and you… that is, if we live in parallel universes. Imagine you doing exactly what you’re doing now, but in an infinite number of universes. Discover the multiverse theory and why repeats aren’t limited to summer television. Plus, the physics of riding on a light beam, and the creative analogies a New York Times science writer uses to avoid using the word “weird” to describe dark energy and other weird physics. Also, people who concoct their own theories (some would say fringe) of the universe: is all matter made up of tiny coiled springs?
