Bill Nye is one of America's leading popularizers of the scientific outlook. As a scientist, engineer, comedian, author, and inventor, he hosted Bill Nye The Science Guy, which earned 28 Emmys during its six year run. He is the author of a number of children's books about science and regularly lectures at Cornell University as part of the Frank H.T. Rhodes Visiting Professorship. He is also a Fellow of CSICOP, the Committee for the Scientific Investigation of Claims of the Paranormal. His acclaimed new show The Eyes of Nye currently airs on PBS stations across the United States.

In this discussion with DJ Grothe, Bill Nye talks about the importance of science literacy, and how science best equips us to face the pressing challenges that threaten our future.
