In advance of President Obama's speech, The Takeaway is asking the difficult questions the President will likely ignore on Tuesday. In 2013, what should weigh on American minds?

Lisa Randall, Professor of Physics at Harvard University, and author of Knocking on Heaven's Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World and Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions, talks about the new discoveries in field of physics, including new evidence for the existence of the Higgs boson. She’ll explain what it is and why it matters. Her most recent book is the Kindle Single Higgs Discovery: The Power of Empty Space.

Friday on The Takeaway means a chance to look back at this week’s big stories. Talking about the new employment numbers, Anderson Cooper, the Higgs Boson particle and more are Jeff Yang, Charlie Herman, and Lisa Randall.

Harvard physicist Lisa Randall is at the forefront of the search for new theories about how the universe works.  She’s especially interested in dark matter and is involved in work at the Large Hadron Collider at CERN.  And although her work requires complex math and work on the theoretical ...

Bonus Track: Kurt's extended conversation with Lisa Randall

Lisa Randall is a professor of physics at Harvard University and the author of Knocking on Heaven's Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World. Randall will discuss the latest news about the recently discovered particle that is consistent with the Higgs boson, the final major component of the Standard Model.

Lisa Randall, professor of science at Harvard University and author of Knocking on Heaven's Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World, reviews an announcement from the CERN physics lab in Europe that scientists may have glimpsed the Higgs boson, also known as the "God Particle."

Near Geneva, Switzerland scientists from the European Center for Nuclear Research are scheduled to present preliminary evidence in their search to find the Higgs boson particle, commonly known as the "God particle." Proving its existence would validate the leading theory of particle physics.

Lisa Randall explains the latest developments in physics that have the potential to radically change our understanding of the world—its makeup, its evolution, and the fundamental forces that drive it. In Knocking on Heaven's Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World she explores the role of risk, creativity, uncertainty, beauty, and truth in scientific thinking through conversations with leading figures in other fields (such as the chef David Chang, the forecaster Nate Silver, and the screenwriter Scott Derrickson). She also explains the latest ideas in physics and cosmology.

Please Explain is all about matter, anti-matter, and dark matter. Lisa Randall, Professor of Theoretical Physics at Harvard University; Michael Tuts, Professor of Physics at Columbia University and Mordecai Mark Mac-Low, Chair of the Department of Physics at the American Museum of Natural History tell us all about what it is and what it means.

In the 1920s, developments in physics from relativity to quantum mechanics were front page news stories. Only today have scientists been able to build machines able to test theories thought up decades ago that predict what matter and energy look like in extreme states. Scientists in Switzerland came a small step closer to testing some of those theories, as the Large Hadron Collider started smashing particles yestserday.

It's not only artists who rebel against time, many physicists too take issue with our standard notion of clock time. Some even deny time exists at all. Blame Einstein. We peer into Pandora's box of post-Einsteinian physics with Brian Greene, Michio Kaku and Lisa ...

Theoretical physicist Lisa Randall believes there are more dimensions to space - possibly 13 more -- than the three we experience. She's faced the challenge of describing a world that no one can see. Produced by Sarah Lilley.
