Lawrence Berkeley National Laboratory physicist and dark energy hunter David Schlegel chats with Sabin Russell, former San Francisco Chronicle reporter turned Berkeley Lab science writer, June 22, 2011. Their conversation is the first instalment of "Sit Down With Sabin," a weekly conversation hosted by Russell. Over the course of five conversations with Berkeley Lab staff this summer, Russell will explore the ups and downs of innovative science - all without the aid of PowerPoint slides.
