The World Science Festival: Making science sexy

The four-day World Science Festival kicks off today in New York City, promising to attract leading scientists, performers, and thousands of attendees.

Actor Alan Alda and physicist Brian Greene join the AM crew this morning to discuss the importance of making science accessible and exciting to a broad audience. Author of the bestseller "The Elegant Universe," Greene co-founded the festival where Alda's play on Marie Curie will be featured in tonight's opening gala.
