Host: Chris Mooney

Our guest this week is Lisa Randall, the Harvard theoretical physicist and one of the most heavily cited and influential researchers in her field. She's a member of a number of distinguished scientific societies, including the National Academy of Sciences—but she's also a very popular science author, behind the bestselling Warped Passages: Unraveling the Universe's Hidden Dimensions, and more recently Knocking on Heaven's Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World, which is just out in paperback.

Between the hardback and paperback release of Knocking on Heaven's Door, a subject much discussed in the book—the quest for the discovery of the Higgs boson—was actually completed. Or at least, scientists at the Large Hadron Collider found a particle that sure looks like the Higgs.

Randall has a new e-book about this entitled Higgs Discovery: The Power of Empty Space. So we were thrilled to speak with her about the Higgs, and what the discovery means about the ability of physics to continually peel back new layers of the universe.
