Lisa Randall: Do you believe in absolute truth?
Lisa Randall studies theoretical particle physics and cosmology at Harvard University. Her research connects theoretical insights to puzzles in our current understanding of the properties and interactions of matter. She has developed and studied a wide variety of models to address these questions, the most prominent involving extra dimensions of space. Her work has involved improving our under-standing of the Standard Model of particle physics, supersymmetry, baryogenesis, cosmological inflation, and dark matter. Randall’s research also explores ways to experimentally test and verify ideas and her current research focuses in large part on the Large Hadron Collider and dark matter searches and models.
Randall has also had a public presence through her writing, lectures, and radio and TV appearances. Randall’s books, Warped Passages: Unraveling the Mysteries of the Universe’s Hidden Dimensions and Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World were both on the New York Times’ list of 100 Notable Books of the Year. Higgs Discovery: The Power of Empty Space was released as a Kindle Single in the summer of 2012 as an update with recent particle physics developments.
Randall’s studies have made her among the most cited and influential theoretical physicists and she has received numerous awards and honors for her scientific endeavors. She is a member of the National Academy of Sciences, the American Philosophical Society, the American Academy of Arts and Sciences, was a fellow of the American Physical Society, and is a past winner of an Alfred P. Sloan Foundation Research Fellowship, a National Science Foundation Young Investigator Award, a DOE Outstanding Junior Investigator Award, and the Westinghouse Science Talent Search. Randall is an Honorary Member of the Royal Irish Academy and an Honorary Fellow of the British Institute of Physics. In 2003, she received the Premio Caterina Tomassoni e Felice Pietro Chisesi Award, from the University of Rome, La Sapienza. In 2006, she received the Klopsteg Award from the American Society of Physics Teachers (AAPT) for her lectures and in 2007 she received the Julius Lilienfeld Prize from the American Physical Society for her work on elementary particle physics and cosmology and for communicating this work to the public.
Randall has also pursued art-science connections, writing a libretto for Hypermusic: A Projective Opera in Seven Planes that premiered in the Pompidou Center in Paris and co-curating an art exhibit for the Los Angeles Arts Association, Measure for Measure, which was presented in Gallery 825 in Los Angeles, at the Guggenheim Gallery at Chapman University, and at Harvard’s Carpenter Center. In 2012, she was the recipient of the Andrew Gemant Award from the American Institute of Physics, which is given annually for significant contributions to the cultural, artistic, or humanistic dimension of physics.
Professor Randall was on the list of Time Magazine's "100 Most Influential People" of 2007 and was one of 40 people featured in The Rolling Stone 40th Anniversary issue that year. Prof. Randall was featured in Newsweek's "Who's Next in 2006" as "one of the most promising theoretical physicists of her generation" and in Seed Magazine's "2005 Year in Science Icons". In 2008, Prof. Randall was among Esquire Magazine's “75 Most Influential People.”
Professor Randall earned her PhD from Harvard University and held professorships at MIT and Princeton University before returning to Harvard in 2001. She is also the recipient of honorary degrees from Brown University, Duke University, Bard College, and the University of Antwerp.
Lisa Randall: Do I believe in absolute truth? I believe in effective theories, so let me tell you what an effective theory is. An effective theory says basically that I can . . . If I can’t measure something, I don’t have to worry about it in the sense that, for example . . . Let’s take Newton’s laws. Newton’s laws work just fine. But we know that eventually we have to take into account relativity, if things were going really fast where we have to take into account quantum mechanics when we’re looking at really tiny scales. But for the scales we observe, you don’t have to worry about the fact that a ball is made up of atoms. It’s perfectly fine to think of it as a ball with some mass because you would never be able to measure the effects of the atoms on the ball when you’re just throwing the ball. So I guess I believe that we . . . There’s a truth that we know because it applies to the world as we’ve seen it, as we’ve measured it. That’s not to say that there can’t be other underlying truths you could see if you could understand . . . if you could really see things better; if you could test them better; if you could measure them better. So I think anything we know could be upset if you look at regimes outside the regime of which we studied them. So . . . But that’s not to say the truth isn’t absolute. It’s absolute in the scales that we’ve seen it; but it’s just not absolute in the sense of applying the most fundamental skills. Recorded On: 11/2/07

- Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
- Wrong! Neither Venus nor Mars is the right answer.
