We learn in school that matter comes in three states: solid, liquid, and gas. Later on we may learn about plasma as being a fourth state.

What does this new type of matter do? And what new and surprising applications will this bring about? Michael Robinson talks with Professor Ketterle about his breakthrough discovery.
