Sagan on the 4th Dimension

In honor of the return of "Cosmos," which we covered here on Big Think, check out classic footage from the original show. A lot has changed since "Cosmos" first aired. We know more now than we did back then, and science today is strangely debated between, well, scientists and creationists. Watch our interview with Bill Nye explaining why creationism is not appropriate for children.

Neil deGrasse Tyson, everybody's favorite astrophysicist and the new host of "Cosmos," explained that part of his inspiration for doing the show is that he does not want tomorrow's leaders to not know or care about science. 

We look forward to watching his show. "Cosmos" airs this Sunday on FOX and The National Geographic Channel.
