What might words like repentance or forgiveness mean, culturally, in this moment? These are questions of the emerging church, a loosely-defined movement that crosses generations, theologies and social ideologies in the hope of reimagining Christianity. With Phyllis Tickle and Vincent Harding, an honest and sometimes politically incorrect conversation on coming to terms with racial identity in the church and in the world.

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.

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.

What happens when you bring together science and poetry on something like color or light? Arthur Zajonc is a physicist and contemplative. And he says we can all investigate life as vigorously from the inside as from the outside.

A mission scientist with NASA’s Kepler Space Telescope, Natalie Batalha hunts for exoplanets — Earth-sized planets beyond our solar system that might harbor life. She speaks about unexpected connections between things like love and dark energy, science and gratitude, and how “exploring the heavens” brings the beauty of the cosmos and the exuberance of scientific discovery closer to us all.

How can unimaginable social change happen in a world of strangers? Kwame Anthony Appiah is a philosopher who studies ethics and his parents’ marriage helped inspire the movie Guess Who’s Coming to Dinner. In a tense moment in American life, he has refreshing advice on simply living with difference.

The push and pull between religion and science has shaped advances in geology from the beginning. David Montgomery set out to debunk Noah’s Flood; instead he discovered this biblical story was the plate tectonics of its day. He tells us how the evolution of landscapes and geological processes shape ecology and humanity. And, how we should read rocks for the stories they tell about who we are and where we came from.

A kind of archeologist of the human voice, singer and composer Meredith Monk says that “the voice could be like the body” — flexible and fluid with practice. Through music as through meditation, the longtime Buddhist practitioner pushes the boundaries of what we can do without words.

Sarah Kay says that listening is the better part of speaking. A spoken word poet who’s become a role model for teenagers around the world, she shares how she works with words to make connections — inside people and between them.

Are we in the matrix? Physicist James Gates reveals why string theory stretches our imaginations about the nature of reality. Also, how failure makes us more complete, and imagination makes us more knowledgeable.

You might call Tami Simon a spiritual entrepreneur. She’s built a successful multimedia publishing company with a mission to disseminate “spiritual wisdom” by diverse teachers and thinkers like Pema Chödrön and Eckhart Tolle, Daniel Goleman and Brené Brown. She offers compelling lessons on joining inner life with life in the workplace — and advice on spiritual practice with a mobile device.

Disruption is around every corner by way of globally connected economies, inevitable superstorms, and technology’s endless reinvention. But most of us were born into a culture which aspired to solve all problems. How do we support people and create systems that know how to recover, persist, and even thrive in the face of change? Andrew Zolli introduces “resilience thinking,” a new generation’s wisdom for a world of constant change.

One of the values of science is to make us uncomfortable says Lawrence Krauss. The particle physicist explains why we should all care about dark energy and the Higgs Boson particle. Science literacy matters, and, more importantly, he suggests we should take joy in science — just as we cultivate enjoyment of arts we may not completely comprehend.
