Joan Snyder paints her way through pain and pleasure. Last year, her 40-year career as an abstract painter was recognized by the MacArthur Foundation with a $500,000 fellowship. But Joan didn't always want to be a painter. Also in this episode, for Maggie Turnbull, the search for extra-terrestrial life is a personal mission, ever since she saw the movie "Contact" years ago. She talks to Dick about how scientists try to look for signs of life 'out there', and what drives her to do so.
