Alex Bacon interviews Mary Corse whose paintings are on view at Lehmann Maupin, New York, through June 13, 2015.

Corse comments: "What interests me now a lot too, especially with the black and white paintings, is when I put the black and the white together: that edge. It’s so optical. It starts flashing. We’ve never seen energy. And you actually start to see energy. And in the thin ones, if I make the line thin enough, I can actually see an energy field. So, on the side, I think I’m interested in seeing energy. That’s a new concern."
