Some of the biggest philosophical and ethical questions of this century may be raised on scientific frontiers — as we gain a better understanding of the deep structure of space and time and the wilder “microworld.” Astrophysicist Martin Rees paints a fascinating picture of how we might be changed by what we do not yet know: “If science teaches me anything, it teaches me that even simple things like an atom are fairly hard to understand. And that makes me skeptical of anyone who claims to have the last word or complete understanding of any deep aspect of reality.” This is On Being’s complete, unedited interview with Lord Rees.

Parallel realities and the deep structure of space-time sound like science fiction. These are matters of real scientific inquiry. Lord Martin Rees is an astrophysicist and self-professed atheist who paints a fascinating picture of how we might be changed by what we do not yet know.

What if we understand death as a developmental stage — like adolescence or mid-life? Dr. Ira Byock is a leading figure in palliative care and hospice in the United States. He says we lose sight of “the remarkable value” of the time of life we call dying if we forget that it’s always a personal and human event, and not just a medical one. From his place on this medical frontier, he shares how we can understand dying as a time of learning, repair, and completion of our lives.

The light and smells in places like hospitals can often depress us. And, our favorite room at home keeps us sane. But why? Immunologist Esther Sternberg explains the scientific research revealing how physical spaces create stress and make us sick — and how good design can trigger our “brain’s internal pharmacies” and help heal us.

David Sloan Wilson believes that evolution is not just a description of how we got here. He says it can also be a tool kit for improving how we live together. He’s taken what he’s learned in studying evolution in animals and is now applying it to the behavior of groups in his hometown of Binghamton, New York. His goal is to help people behave pro-socially — at their best, and for the good of the whole. This is Krista Tippett’s complete, unabridged conversation with David Sloan Wilson that’s included in the show “Evolving a City.” See more at onbeing.org/program/evolving-city/4720

Keith Devlin is a mathematician and executive director of H-STAR at Stanford University in Palo Alto, California. Krista Tippett spoke with him on July 11, 2013. This interview is included in our show “The Joy of Math.” Download the mp3 of the produced show at onbeing.org.

Mathematical equations are like sonnets says Keith Devlin. What most of us learn in school, he says, doesn’t begin to convey what mathematics is. And technology may free more of us to discover the wonder of mathematical thinking — as a reflection of the inner world of our minds.
