As a dancer and choreographer I’ve spent a tremendous amount of my life defending something that’s very hard to see. I mean, people see dance, they see the dancers, but they have trouble understanding why it’s valuable, what you are trying to say. And in some ways I feel that’s reflected in what I learned initially from the physicists. It’s very abstract, it’s hard to see, people have trouble trying to understand it. It has tremendous value to us as a civilization but it’s not easy to explain.
